22 páginas.- 6 figuras.- 6 tablas.- 41 referencias.- (This article belongs to the Special Issue Future of Irrigation in Agriculture), The tomato cultivated surface is one of the most important surfaces in the world. This crop needs a sufficient and continuous supply of water during vegetative growth. Therefore, production may be at risk in warm and water-scarce areas. Therefore, the implementation of irrigation alternatives such as regulated deficit irrigation (RDI) is of great importance to reduce the use of water and improve the production of the quality of tomatoes. The objective of this work was to evaluate the deficit irrigation scheduling using plant water status as a tool in deficit irrigation. Experimental design was a randomized design with four replications per treatment. Two irrigation treatments were applied: Control (125% of crop evapotranspiration (ETc)) and Regulated Deficit Irrigation (RDI). This latter treatment considered different threshold values of midday leaf water depending on crop phenological stage. No differences were observed in yield, with RDI treatment being more efficient in the use of irrigation water than the control. Besides, RDI tomatoes presented, in general, greater weight, size, Total soluble solids (TSS), sugars, antioxidant activity, lycopene, β-Carotene, and redder color with more intense tomatoes flavor. Finally, it might be said that RDI strategy helped to reduce 53% of irrigation water and to improve the nutritional, functional, and sensory quality of tomatoes.

Objective To investigate the barriers and facilitators of adherence to methotrexate (MTX) in people with rheumatic diseases and to explore the experience of shared decision-making. Methods A qualitative study was carried out. People diagnosed with inflammatory arthritides or systemic autoimmune diseases and who were treated with MTX were invited to participate in focus groups. The discourse was coded and synthesised with a content analysis approach. Results The groups included 12 representative patients (rheumatoid arthritis, spondylarthritis, and systemic lupus erythematosus, taking either oral or subcutaneous MTX). Four main themes were identified: (1) drug-related aspects (package insert, adverse events, administration, and difficulties with treatment); (2) patient-physician relationship; (3) social environment (lack of visibility of rheumatic diseases and the support of patient associations); and (4) medication and medical care practicalities (information, reliable sources, and expanding knowledge in other health areas). Conclusions Aspects identified might help improve adherence, including quality information, especially on adverse events, the role of the setting, and shared decision-making.

The main objective of this research was to carry out an experimental study, triple-blind, on the possible immunophysiological effects of a nutritional supplement (synbiotic, Gasteel Plus®, Heel España S.A.U.), containing a mixture of probiotic strains, such as Bifidobacterium lactis CBP-001010, Lactobacillus rhamnosus CNCM I-4036, and Bifidobacterium longum ES1, as well as the prebiotic fructooligosaccharides, on both professional athletes and sedentary people. The effects on some inflammatory/immune (IL-1β, IL-10, and immunoglobulin A) and stress (epinephrine, norepinephrine, dopamine, serotonin, corticotropin-releasing hormone (CRH), Adrenocorticotropic hormone (ACTH), and cortisol) biomarkers were evaluated, determined by flow cytometer and ELISA. The effects on metabolic profile and physical activity, as well as on various parameters that could affect physical and mental health, were also evaluated via the use of accelerometry and validated questionnaires. The participants were professional soccer players in the Second Division B of the Spanish League and sedentary students of the same sex and age range. Both study groups were randomly divided into two groups: a control group—administered with placebo, and an experimental group—administered with the synbiotic. Each participant was evaluated at baseline, as well as after the intervention, which lasted one month. Only in the athlete group did the synbiotic intervention clearly improve objective physical activity and sleep quality, as well as perceived general health, stress, and anxiety levels. Furthermore, the synbiotic induced an immunophysiological bioregulatory effect, depending on the basal situation of each experimental group, particularly in the systemic levels of IL-1β (increased significantly only in the sedentary group), CRH (decreased significantly only in the sedentary group), and dopamine (increased significantly only in the athlete group). There were no significant differences between groups in the levels of immunoglobulin A or in the metabolic profile as a result of the intervention. It is concluded that synbiotic nutritional supplements can improve anxiety, stress, and sleep quality, particularly in sportspeople, which appears to be linked to an improved immuno-neuroendocrine response in which IL-1β, CRH, and dopamine are clearly involved.

Highlights • Endurance foot races increase the levels of markers for heart damage, which persist at high levels for a 24-h minimum period. • Gender, body mass index, and intensity of the race exert a moderating effect on the acute increase of troponin T and troponin I. • It is recommended that individuals should be adequately prepared for foot-race competition, particularly races that combine long duration and moderate intensity (i.e., marathons). Men and less experienced or young participants with high fat percentages or high body mass indexes should be especially adequately prepared., Background To finish an endurance race, athletes perform a vigorous effort that induces the release of cardiac damage markers. There are several factors that can affect the total number of these markers, so the aim of this review was to analyze the effect of endurance running races on cardiac damage markers and to identify the factors that modify the levels of segregation of these cardiac damage markers. Methods A systematic search of PubMed, Web of Science, and the Cochrane Library databases was performed. This analysis included studies where the acute effects of running races on cardiac damage markers (troponin I and troponin T) were analyzed, assessing the levels of these markers before and after the races. Results The effects of running races on troponin I (mean difference = 0.0381 ng/mL) and troponin T (mean difference = 0.0256 ng/mL) levels were significant. The ages (R2 = 14.4%, p = 0.033) and body mass indexes (R2 = 14.5%, p = 0.045) of the athletes had a significant interaction with troponin I. In addition, gender, mean speed, time to finish the race, and type of race can affect the level of cardiac damage markers. Conclusion Endurance running races induce the release of cardiac-damage markers that remain elevated for at least 24 h after the races. In addition, young male athletes with high body mass indexes who perform races combining long duration and moderate intensity (i.e., marathons) release the highest levels of cardiac damage markers. Physicians should take into consideration these results in the diagnosis and treatment of patients admitted to the hospital days after finishing endurance running races., Graphical Abstract Image, graphical abstract

BACKGROUND: Low sleep quality, cardiac autonomic dysfunction and poor quality of life are some of the most prevalent symptoms in people with Multiple Sclerosis (MS). In addition to the progression of the disease, these symptoms are aggravated by physical inactivity. Therefore, home confinement due to COVID-19 pandemic restrictions could further worsen these symptoms. This study aims to analyze the effect of home confinement on objective and subjective sleep quality, cardiac autonomic control based on heart rate variability (HRV), and health-related quality of life in people with MS. METHODS: Actigraphic and subjective sleep quality (Karolinska Sleep Diary, KSD), HRV (Polar-H7), and quality of life (Multiple Sclerosis Quality of Life-54) were measured before and after 2 months of home confinement in 17 people with MS (7:10 men/women; age: 43.41±10.88 years; body mass index: 24.87±3.31 kg/m2; Expanded Disability Status Scale: 2.85±1.34 a.u.). RESULTS: Actigraphic sleep quality (sleep efficiency: ES=1.27, p = 0.01, sleep time: ES=0.81, p = 0.01) and subjective sleep quality (sleep quality: ES=-0.34, p = 0.05), sleep comfort: ES=0.60; p = 0.03, ease of falling asleep: ES=0.70; p = 0.01, ease of waking up: ES=0.87, p

Introduction Nerve conduction studies (NCS) have been considered as the gold standard in carpal tunnel syndrome (CTS) diagnosis, despite correlation between clinical symptomatology and NCS severity has shown to be poor. In fact, clinical symptoms precede NCS changes in months or years. Few papers have been published about the clinical response to treatment of clinically typical CTS, but with normal NCS (NNCS). Objective To compare the clinical response to local corticosteroid injections (LCI) in clinically typical CTS, with NNCS and abnormal NCS (ANCS). Method We included patients older than 18, with typical CTS symptoms (ongoing daily nocturnal pain/paresthesias in hand, at least during 3 months). Follow-up was done at 3, 6 and 12 months. Primary outcome was the visual analog scale for pain (p-VAS), comparing NNCS CTS wrists with ANCS CTS wrists. Statistic signification was established by the Student's t test, Mann–Whitney's “U”, χ2 test and Yates’ correction. Results We included 44 wrists in the NNCS group, and 83 in the ANCS group. There was no statistical significance between data in both groups, except in the 12-month follow-up, where the NNCS group achieved better results than the ANCS group in the 20% response (p = 0.006). There was a trend toward a better 50% response in the 12-month follow-up. Conclusions Our data suggest that LCI are similarly effective in both CTS with NNCS and ANCS. Nonetheless, there is a mild better effect in NNCS than in ANCS at 12-month follow-up.

Objectives To assess the effects of whole-body vibration training (WBVT) on body composition, metabolic and cardiovascular risk variables, and lower limb strength in participants who are overweight/obese. Data Sources A systematic review with meta-analysis was conducted in 3 databases (PubMed-MEDLINE, Web of Science, and Cochrane Library) from inception through to January 26, 2020. Study Selection : Studies analyzing the effect of WBVT on body composition variables, metabolic profile, blood pressure, heart rate, and lower limb strength in the population who are overweight/obese, with interventions of a minimum length of 2 weeks were included. Data Extraction After applying the inclusion and exclusion criteria, 23 studies involving 884 participants who were obese/overweight (experimental group: 543; weight=79.9 kg; body mass index (BMI) =31.3 kg/m2, obesity class I according to World Health Organization) were used in the quantitative analysis. The sex of the participants involved in the studies were as follows: (1) 17 studies included only female participants; (2) 1 study included only boys, and (3) 5 studies included both sexes. Meta-analysis, subgroup analysis, and meta-regression methods were used to calculate the mean difference and standardized mean difference (SMD; ± 95% confidence intervals [CIs]) as well as to analyze the effects of pre-post intervention WBVT and differences from control groups. Data Synthesis WBVT led to a significant decrease in fat mass (−1.07 kg, not clinically significant). In addition, WBVT reduced systolic blood pressure (−7.01 mmHg, clinically significant), diastolic blood pressure (−1.83 mmHg), and heart rate (−2.23 bpm), as well as increased the lower extremity strength (SMD=0.63; range, 0.40-0.86). On the other hand, WBVT did not modify the weight, BMI, muscle mass, cholesterol, triglycerides, or glucose. Conclusions WBVT could be an effective training modality to reduce blood pressure (clinically relevant) and resting heart rate. In addition, WBVT led to improved lower limb strength. However, these findings were not consistent with significant improvements on other variables associated with metabolic syndrome (body composition, cholesterol, triglycerides, glucose).

To investigate the prevalence, associated factors, and effects of primary overt renal disease on morbidity in patients with primary Sjögren's syndrome (pSS).All patients in the Sjögrenser (registry of adult pSS patients of the Spanish Society of Rheumatology) cohort were retrospectively investigated for the presence of clinically significant renal involvement directly related to pSS activity.Of the 437 patients investigated, 39 (9%) presented overt renal involvement during follow-up. Severe renal disease necessitating kidney biopsy was relatively rare (2%). Renal involvement may complicate pSS at any time during the disease course and is associated with severe disease (indicated by higher scores of involvement, activity, and damage), systemic multiorgan involvement, and a higher frequency of lymphoma. Multivariate analysis showed that older age (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.00-1.07), higher European League Against Rheumatism Sjögren's Syndrome Disease Activity Index scores (OR 1.1, CI 1.03-1.18), serum anti-La/SSB positivity (OR 6.65, CI 1.41-31.372), and non-vasculitic cutaneous involvement (OR 5.47, 1.03-29.02) were independently associated with this complication. Chronic renal failure developed in 23 of 39 patients (59%); only 1 of them progressed to end-stage renal disease necessitating renal replacement therapy. Patients with overt renal disease showed higher Sjögren's syndrome disease damage index scores, higher rates of hospitalisation due to disease activity and higher rates of clinically relevant comorbidities.Overt renal involvement in pSS is not uncommon. Although it usually shows a favourable prognosis, is associated with significant morbidity.

Objectives: This study aims to analyse the validity (agreement between two methods) of the movement propulsive velocity (MPV) as an indicator of relative load in leg press (LP) and bench press (BP) exercises in persons with multiple sclerosis (MS). Methods: 18 persons with MS (sex = 55% male, age (mean SD) = 44.88 10.62 years, body mass = 67.19 10.63 kg, height = 1.66 0.07 m, Expanded Disability Status Scale (EDSS) = 3.12 1.73) performed an incremental loading test in BP and LP exercises in two separate sessions. Individual determination of the one-repetition maximum (1RM) and full load-velocity profile were obtained for each participant. Results: a significant linear relationship was observed between the %1RM load and the MPV in LP (%1RM = &minus, 133.58 &times, MPV + 117.44, r2 = 0.84, standard error of the estimate (SEE) = 9.38%1RM) and BP (%1RM = &minus, 95.66 &times, MPV + 115.26, r2 = 0.86, SEE = 9.82%1RM). In addition, no significant differences were found between the %1RM achieved directly and the %1RM obtained by the equation calculated from the linear regression (LP, p = 0,996, BP, p = 0,749). Conclusions: these results indicate that movement velocity can estimate the relative load in bench press and leg press exercises in persons MS.

Patients with renal disease showed higher Sjögren’s syndrome disease damage index scores, higher rates of hospitalization due to disease activity and higher rates of clinically relevant comorbidities.Conclusion Renal involvement is an uncommon complication in pSS that was observed in 9% of patients. Although categorized as a non-negligible comorbidity, this condition shows a favorable prognosis.

Objective To describe the progress of the attractiveness of rheumatology at successive MIR calls, from 1983 to 2014. Methods Candidates in the Spanish training system for medical doctors choose their specialties sequentially, ordered by their ranking in the qualifying exam (MIR). The highest, median and lowest rank of candidates choosing rheumatology training positions in every MIR call from 1983 to 2014 was requested from the Department of Management of Specialized Medical Training (General Department of Professional Regulation; Spanish Ministry of Health). To compare, the same data was requested for other specialties. In order to define and analyze the attractiveness of each specialty we introduce an ‘index of attractiveness’, based on the normalized difference of the actual median rank reported for each year and the average median obtained in 1000 simulations in which candidates choose specialties at random. Results Regarding the median of the election of rheumatology, the range went from 244th in 1983 to 3394th in 2008, showing a progressive increase over the years in absolute figures. A mathematical simulation allowed quantifying the difference between the observed median and what would have happened if specialties had been chosen by pure chance. Results show a tendency to recover the attractiveness of rheumatology in recent years. Conclusions After a sharp decline in the attractiveness of rheumatology during the last years of the 20th century, there seems to be a recovery.

Objective To develop evidence-based recommendations on the use of ultrasound (US) and magnetic resonance imaging in patients with spondyloarthritis, including psoriatic arthritis, and juvenile idiopathic arthritis. Methods Recommendations were generated following a nominal group technique. A panel of experts (15 rheumatologists and 3 radiologists) was established in the first panel meeting to define the scope and purpose of the consensus document, as well as chapters, potential recommendations and systematic literature reviews (we used and updated those from previous EULAR documents). A first draft of recommendations and text was generated. Then, an electronic Delphi process (2 rounds) was carried out. Recommendations were voted from 1 (total disagreement) to 10 (total agreement). We defined agreement if at least 70% of participants voted ≥7. The level of evidence and grade or recommendation was assessed using the Oxford Centre for Evidence Based Medicine levels of evidence. The full text was circulated and reviewed by the panel. The consensus was coordinated by an expert methodologist. Results A total of 12 recommendations were proposed for each disease. They include, along with explanations of the validity of US and magnetic resonance imaging regarding inflammation and damage detection, diagnosis, prediction (structural damage progression, flare, treatment response, etc.), monitoring and the use of US guided injections/biopsies. Conclusions These recommendations will help clinicians use US and magnetic resonance imaging in patients with spondyloarthritis and juvenile idiopathic arthritis.

Resumen Objetivo Establecer recomendaciones, basadas en la evidencia, sobre el uso de la ecografia (US) y la resonancia magnetica en pacientes con espondiloartritis, incluyendo la artritis psoriasica, y en la artritis idiopatica juvenil. Metodos Las recomendaciones se consensuaron mediante metodologia basada en grupos nominales. Un grupo de expertos (15 reumatologos y 3 radiologos) definio el alcance, los usuarios, los apartados, las posibles recomendaciones y las revisiones sistematicas a realizar (se utilizaron y actualizaron las revisiones de documentos de consenso de EULAR), y se asignaron tareas. Los expertos delimitaron los apartados y redactaron las recomendaciones. El nivel de evidencia y el grado de recomendacion se establecieron utilizando el sistema del Centre for Evidence Based Medicine de Oxford, y el grado de acuerdo mediante Delphi a 2 rondas. Las recomendaciones se votaron segun una escala de 1 (total desacuerdo) a 10 (total acuerdo), definiendose el acuerdo como una puntuacion ≥ 7 por al menos el 70% de los participantes. El documento fue revisado por los expertos y el proyecto estuvo coordinado por un metodologo experto. Resultados Se emitieron 12 recomendaciones sobre la validez de la US y la resonancia magnetica para la deteccion de actividad y dano estructural, capacidad diagnostica, predictora (de progresion de dano estructural, brote de la enfermedad, respuesta al tratamiento, etc.), utilidad en la evaluacion y monitorizacion del tratamiento, y uso de la US como guia (para infiltraciones, biopsias, etc.) en pacientes con espondiloartritis y artritis idiopatica juvenil. Conclusiones Se presentan unas recomendaciones utiles para el manejo de la US y la resonancia magnetica por los clinicos en pacientes con espondiloartritis y artritis idiopatica juvenil.

Background The COVID-19 pandemic caused a global confinement of more than 2 months in Spain. As a result, the general population has significantly decreased their physical activity levels. The consequences of this abrupt, sedentary lifestyle in Spanish people with Multiple Sclerosis (pwMS) were unknown. Our aim was to examine the impact of COVID-19 home confinement on neuromuscular performance, functional capacity, physical self-perception, and anxiety in pwMS. Methods Eighteen pwMS (8:10 men/women, age: 43.41±10.88 years, Expanded Disability Status Scale: 2.85±1.34) participated in the study. Rate of force development (RFD) and maximal voluntary isometric contraction during knee extension in both legs, Timed-Up and Go test (TUG), sit-to-stand test, 6 min walk test, 10 m walk test, Physical-Self Perception Questionnaire (PSPQ) and State-Train Anxiety Inventory (STAI) were performed just before and after home confinement. Results A non-significant moderate effect (p = 0.07; ES = -0.48) was observed in the time in the sit-to-stand test compared to pre-home confinement. There was a significant increase in the time in TUG (p = 0.02; ES = -0.67). The PSQP score decreased (p = 0.01; ES = 0.79) and STAI-state increased (p = 0.01; ES = -0.65) following home confinement. Conclusion Home confinement had an impact on functional capacity, physical self-perception and state anxiety. However, neuromuscular performance was not altered after home confinement.

El diagnóstico y tratamiento de las enfermedades autoinmunes sistémicas (EAS) constituye un reto. Aunque infrecuentes, afectan a cientos de miles de pacientes en España. El médico de familia (MF) se enfrenta a síntomas o signos inespecíficos que hacen sospechar EAS al inicio del proceso, y tiene que decidir a quiénes debería derivar. Para facilitar su reconocimiento y mejorar su derivación, expertos de la Sociedad Española de Medicina de Familia y Comunitaria y de la Sociedad Española de Reumatología seleccionaron 26 síntomas/signos-guía y alteraciones analíticas. Se escogieron parejas de MF y reumatólogo para elaborar algoritmos diagnósticos y de derivación. Posteriormente se revisaron y adaptaron al formato de aplicación para móviles (app) descargable. El resultado es el presente documento de derivación de EAS para MF en formato de papel y app. Contiene algoritmos de fácil manejo utilizando datos de la anamnesis, exploración física y pruebas analíticas accesibles en atención primaria para orientar el diagnóstico y facilitar la derivación a reumatología o a otras especialidades. Management of systemic autoimmune diseases is challenging for physicians in their clinical practice. Although not common, they affect thousands of patients in Spain. The family doctor faces patients with symptoms and non-specific cutaneous, mucous, joint, vascular signs or abnormal laboratory findings at the start of the disease process and has to determine when to refer patients to the specialist. To aid in disease detection and better referral, the Spanish Society of Rheumatology and the Spanish Society of Family Medicine has created a group of experts who selected 26 symptoms, key signs and abnormal laboratory findings which were organized by organ and apparatus. Family doctors and rheumatologists with an interest in autoimmune systemic diseases were selected and formed mixed groups of two that then elaborated algorithms for diagnostic guidelines and referral. The algorithms were then reviewed, homogenized and adapted to the algorithm format and application for cell phone (apps) download. The result is the current Referral document of systemic autoimmune diseases for the family doctor in paper format and app (download). It contains easy-to-use algorithms using data from anamnesis, physical examination and laboratory results usually available to primary care, that help diagnose and refer patients to rheumatology or other specialties if needed.

OBJECTIVES: To explore the remission concept in rheumatoid arthritis (RA) and the implications of the existing definitions when applied to clinical practice among rheumatologists with different profiles. METHODS: A qualitative study through focus groups was conducted. Three focus groups were organised from February to March 2016. Each group was composed of rheumatologists with extensive clinical experience with different profiles; experts in basic research (RBR), experts in imaging techniques research (RIR), and experts in clinical research (RCR). The data was collected with audio recording. Verbatim transcriptions of the audio files were made, and a subsequent reflexive thematic analysis assisted by ATLAS.ti (GmbH, Berlin, v. 7) software was performed. RESULTS: From the reflexive thematic analysis, three main themes were generated: (1) remission limitations, (2) instruments or measures to assess remission, and (3) a new definition of remission. Rheumatologists mentioned frequently that the following variables should be considered when developing a new remission definition: inflammatory activity, calprotectin, psychological variables, sex, disease stage, and sociocultural factors. Contrary to what could be expected, all groups acknowledged that their research field could contribute with domains for a gold standard remission instrument, but not in a hierarchical arrangement of importance. The dissonance existing in the entire remission evaluation process was outlined: remission in clinical practice versus remission in clinical trials, remission following the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) Boolean versus Musculoskeletal Ultrasound (US) remission, and remission from the rheumatologist's point of view versus the patient's point of view. CONCLUSIONS: Currently, rheumatologists would not accept a domain as more important than others in remission. Our suggestion is, not to generate a universal definition of remission - one that could cover all aspects - but rather to develop definitions of remission for the different settings that could be pondered by the patient's perspective.

The aim of this study was to investigate the acute effects of vibration training (WBVT) under hypoxic and normoxic conditions on the voluntary rate of force development (RFD), balance and muscle oxygen saturation (SMO2) in persons with Multiple Sclerosis (MS). 10 participants completed the study (30% males, 44.4±7.7 years, 164.3±8.9 cm, 65.2±11.1 kg, 2.5±1.3 Expanded Disability Status Scale, 24.1±4.0 kg.m−2 BMI). Maximal force, RFD during isometric knee extension, static balance with eyes open and closed and sit-to-stand test were evaluated before and immediately after one session of WBVT (12 60-s bout of vibration; frequency 35 Hz; amplitude 4 mm; 1-min rest intervals) under both normoxic and hypoxic conditions. In addition, SMO2 of the gastrocnemius lateralis was assessed during each condition. No changes were found in force, static balance and sit-to-stand test. Time-to-peak RFD increased in the left leg (p=0.02) and tended to increase in the right leg (p=0.06) after the hypoxic session. SMO2 resulted in significant increases from the initial to final intervals of the WBVT under both hypoxic and normoxic conditions (p

This study aimed at determining socio-demographic and clinical factors of primary Sjögren syndrome (pSS) associated with osteoporosis (OP) and fragility fracture. SJOGRENSER is a cross-sectional study of patients with pSS, classified according to American European consensus criteria developed in 33 Spanish rheumatology departments. Epidemiological, clinical, serological and treatment data were collected and a descriptive analysis was conducted. Bivariate and multivariate analyses were performed using a binomial logistic regression to study the factors associated with OP and fragility fracture in pSS. 437 patients were included (95% women, with a median age of 58.6 years). 300 women were menopausal (76.4%). Prevalence of OP was 18.5% [in men (N = 21) this measured 19%]. A total of 37 fragility fractures were recorded. In the multivariate analysis, there was an association between OP and age: in the 51-64 age range (menopausal women), the OR measured 9.993 (95% CI 2301-43,399, p = 0.002); In the age 64 years group, OR was 20.610 (4.679-90.774, p 0.001); between OP and disease duration, OR was 1.046 (1.008-1085, p = 0.017); past treatment with corticosteroids, OR 2.548 (1.271-5.105, p = 0.008). Similarly, an association was found between fragility fractures and age: in the 51-64 age group, OR measured 5.068 (1.117-22,995, p = 0.035), age 64 years, OR was 7.674 (1.675-35,151, p 0.009); disease duration, OR 1.049 (CI 1.003-1097, p 0.036) and the ESSDAI index, OR 1.080 (1.029-1134, p = 0.002). Patients with pSS can develop osteoporosis and fragility fractures over the course of the disease. Age, corticosteroids treatment and disease duration were associated with the development of OP. Disease duration and ESSDAI were associated with the development of fractures in patients with pSS.

Objective: To describe the incidence of bacteremia in a large multicentric cohort of patients with systemic lupus erythematosus (SLE) and their clinical characteristics and to identify risk factors. Methods: All bacteremic episodes from the Spanish RELESSER registry were included. Clinical and laboratory characteristics concerning bacteremia and SLE status, as well as comorbidities at the time of infection, were retrospectively collected. A comparison with sex- and age-matched SLE controls without bacteremia was made. A logistic regression was conducted. Results: The study included 114 episodes of bacteremia in 83 patients. The incidence rate was 2.7/1000 patient-years. At the time of bacteremia, the median age was 40.5 (range: 8-90) years, and 88.6% of patients were female. The Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index was 4 [interquartile range (IQR) 8]; 41% had an SLE flare (66% severe); Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index was 3 (IQR 4). A comorbidity was recorded in 64% of cases. At the time of bacteremia, 88.6% received corticosteroids (68.6% > 10 mg/day) and 57% immunosuppressors. Gram-negative bacilli, most frequently Escherichia coli (29.8%), caused 52.6% of the episodes. The bacteremia-related mortality was 14% and bacteremia was recurrent in 27.2% of cases. A dose-response relationship was found between corticosteroids and bacteremia risk. In the multivariate analysis, these factors were associated with bacteremia: elevated creatinine (OR 1.31, 95% CI 1.01-1.70; p = 0.045), diabetes (OR 6.01, 95% CI 2.26-15.95; p < 0.001), cancer (OR 5.32, 95% CI 2.23-12.70; p < 0.001), immunosuppressors (OR 6.35, 95% CI 3.42-11.77; p < 0.001), and damage (OR 1.65, 95% CI 1.31-2.09; p < 0.001). Conclusion: Bacteremia occurred mostly in patients with active SLE and was frequently associated with severe flares and corticosteroid use. Recurrence and mortality were high. Immunosuppressors, comorbidities, and disease-related damage were associated with bacteremia. This work was supported by the Spanish Foundation of Rheumatology.

18 páginas.- 9 figuras.- 3 tablas.- 46 referencias, Deficit irrigation scheduling is becoming increasingly important under commercial conditions. Water status measurement is a useful tool in these conditions. However, the information about water stress levels for olive trees is scarce. The aim of this experiment was to evaluate the effect on yield of a moderate controlled water stress level at the end of the irrigation season. The experiment was conducted in the experimental farm of La Hampa (Coria del Río, Seville, Spain) during three years. A completely randomized block design was performed using three different irrigation treatments. Deficit irrigation was applied several (4 or 2) weeks before harvest. Irrigation was controlled using the midday stem water potential, with a threshold value of −2 MPa and compared with a full irrigated treatment. This water stress did not reduced gas exchange during the deficit period. The effect on yield was not significant in any of the three seasons. In the high-fruit load season, fruit volume was slightly affected (around 10%), but this was not significant at harvest. Results suggest an early affection of fruit growth with water stress, but with a slow rate of decrease. Moderate water stress could be useful for the management of deficit irrigation in table olive trees., This research was supported by the Agencia Española de Investigación (AEI) and the Fondo Europeo de Desarrollo (FEDER) projects AGL2013-45922-C2-1-R and AGL2016-75794-C4-4-R.

Ramos-Campo, DJ, Martínez-Guardado, I, Rubio-Arias, JA, Freitas, TT, Othalawa, S, Andreu, L, Timón, R, and Alcaraz, PE. Muscle architecture and neuromuscular changes after high-resistance circuit training in hypoxia. J Strength Cond Res 35(11): 3035-3040, 2021-This study aimed to analyze the effect of 8 weeks of high-resistance circuit (HRC) training in hypoxia on muscle architecture, strength, and neuromuscular variables. Twenty-eight resistance-trained subjects were assigned to a hypoxia (FiO2 = 15%; HG: n = 15; age: 24.6 ± 6.8 years; height: 177.4 ± 5.9 cm; and mass: 74.9 ± 11.5 kg) or normoxia group (FiO2 = 20.9%; NG: n = 13; age: 23.2 ± 5.2 years; height: 173.4 ± 6.2 cm; and mass: 69.4 ± 7.4 kg). Each training session consisted of 2 blocks of 3 exercises (block 1: bench press, leg extension, and front lat pulldown; block 2: deadlift, elbow flexion, and ankle extension). Each exercise was performed with a 6 repetition maximum load. Subjects exercised twice weekly and, before and after the training program, vastus lateralis muscle thickness and pennation angle, knee extensors electromyographic activity, maximum voluntary contraction (MVC), and rate of force development (RFD) and H-Reflex (Hmax), M-wave of the soleus muscle were assessed. Both training groups showed similar improvements in muscle thickness (effect size [ES] = HG: 0.23; NG: 0.41), pennation angle (ES = HG: 0.86; NG: 0.15), MVC (ES HG: 0.63; NG: 0.61), Hmax (ES = HG: 0.96; NG: 0.40), RFD at 200 milliseconds (ES = HG: 0.31; NG: 0.61) and peak RFD (ES = HG: 0.21; NG: 0.66). No significant between-group differences were found. In conclusion, similar morphological and neuromuscular adaptations can be achieved after 8 weeks of HRC training under hypoxic or normoxic conditions.

Background Primary Sjogren’s syndrome (pSS) is characterized by lymphocytic infiltration of the exocrine glands. These patients have a higher risk than the general population of developing non-Hodgkin lymphoma (NHL). This risk also increases with the time of evolution of the disease. pSS is also associated with the development of non-hematological cancer such as thyroid, digestive or gynecological among others. Objectives The aim of the study is to explore the association between the development of neoplasia and demographic, clinical or therapeutic factors in pSS. Methods The SJOGRENSER registry is a multicenter, cross-sectional study of patients with pSS who meet the American-European consensus criteria of 2002, of 33 Spanish rheumatology units. The demographic, clinical, analytical, therapeutic and neoplastic data were collected through review of the clinical records and interviews with the patients. Previously, all the patients signed informed consent and the approval of the local ethic committees was obtained. Descriptive statistics was used for the analysis of the data. The chi-squared test was used to establish the statistical associations and it was considered a p Results Four hundred and thirty-seven patients were included in SJOGREN-SER Registry (female gender 95.19%; median age 58.3 years). We found 30 patients (6.86%) with neoplasia (3 of them with more than one neoplasia): 7 with lymphomas (23.3%) (4 MALT lymphomas, 2 Hodgkin’s lymphomas, 1 immunocytoma), 9 with gynecological neoplasia (30%), 2 with digestive malignancies, 2 with hematological, 2 with endocrine, 6 with malignancies in other locations, 3 with multiple mieloma and 2 patients with Waldenstrom macroglobulinemia. The results of the bivariate analysis are shown in the table. The factors significantly associated with the development of neoplasia were older age, glandular inflammatory involvement, lung involvement and use of rituximab. The age at diagnosis of the disease tended to be higher in the group with neoplasia (50.1 (± 12.9) vs 54.7 (± 11.7), p = 0.059). In the multivariate analysis, positive associations were found for the development of neoplasia in older patients (OR 1.045; CI95% 1.010-1.081), patients with glandular inflammation (OR 3.104; CI95% 1.396-6.906), and use of rituximab (OR 3.745; CI95% 1.386-10.118). Conclusion Thirty (6.86%) patients with pSS from the SJOGRENSER registry developed some neoplasia; the most frequent was gynecological, followed by lymphoproliferative processes. Older age, glandular inflammatory involvement and use of rituximab (presumably indication bias) were associated with the presence of neoplasia. References [1] Brito –Zeron, et al.

Background: Gastric angiodysplasia and the typical “watermelon stomach” aspect is one of the most characteristic vascular manifestations in systemic sclerosis (SS). These angiodysplasias can affect the intestine ocasionally as well as the stomach. Objectives: Description of a series of 5 patients with systemic sclerosis and presence of intestinal angiodysplasia (IA). Methods: Retrospective unicentric observational study in a tertiary hospital. Demographic data, comorbidities, manifestations of the disease, serological profile, concomitant treatments and bleeding manifestations, as well as endoscopic findings and received treatment were collected. Descriptive statistics was used to present the data. Results: We reviewed the medical records of the 88 patients with a diagnosis of SS followed up in the Rheumatology Service. Five cases (5.6%) of IA were identified (4 women and one male), with a mean age of 73 years (SD 13.71). In one case, the diagnosis of SS and IA was simultaneous. In the remaining 4 cases, the mean time from the diagnosis of ES to the diagnosis of the IA was 7.75 years (SD 2.6). Regarding the clinical presentation, 4 of the cases presented as anemia with iron deficiency. In these cases IA were found in the endoscopic studies. In one case, IA were a finding in the context of the study of diarrhea. In 4 of the cases, the IA were in the small intestine, so the diagnosis was made using an endoscopic capsule. In one case they were found in the colon, so the diagnosis was by colonoscopy. Only one of the cases of angiodysplasias in the small intestine required specific treatment with argon laser by enteroscopy. One case required a transfusion of packed red blood cells. In the remaining cases, treatment with oral or intravenous iron therapy was enough. In all 5 cases, it was a limited form of the SS with the presence of anticentromere antibodies. All cases presented Raynaud’s phenomenon, 3 of them with digital ulcers. Three of the cases associated primary biliary cholangitis, 3 cases pulmonary hypertension, 3 cases peristaltic involvement, 1 case interstitial lung disease and 1 case restrictive cardiomyopathy. As comorbidities, we identified 1 case of essential mixed cryoglobulinemia associated with hepatitis C virus, 2 cases of valvular heart disease, 2 cases of atrial fibrillation. Conclusion: The extragastric localization of the angiodysplasias should be taken into account in the patient with SS and iron deficiency, especially in those with a limited form of the illness and positive anticentromere antibodies Disclosure of interests: Carolina Merino argumanez: None declared, Olga Rusinovich: None declared, Maria Espinosa: None declared, Consuelo Ramos Giraldez Speakers bureau: Sanofi, Carmen Barbadillo Mateos: None declared, Jose Luis andreu Sanchez: None declared, Hilda Godoy: None declared

Background: The time of rheumatoid arthritis (RA) evolution until treatment begins is key to controlling the disease. Many studies have shown that a prolonged duration of symptoms at the onset of treatment is associated with a more severe course of RA. The time from symptoms onset to first DMARD prescription is >12 weeks in Spain, because of diagnostic delay due to either patient-related factors (delay in consultation), Primary Care Physician (PCP) (delay in citation/referral) or rheumatologist (delay in citation). Objectives: To evaluate the usefulness of teleconsulting as a preferred referral tool from PCP to Rheumatology for early detection, diagnosis and treatment of inflammatory joint disease in adults, in the health area of a tertiary hospital. Methods: A preferential referral circuit was established between the PCP and the Rheumatology Service of a tertiary hospital, defining the referral criteria as “patient suspected of recent onset arthritis (ROA)”: arthritis or inflammatory arthralgia in >1 peripheral joint for >2 weeks with neither traumatic cause nor previous diagnosis of rheumatic disease. PCP performed first assessment, the request for initial tests (blood test including acute phase reactants, rheumatoid factor ± ANA, elemental urine and hands radiography) as well as the referral to Rheumatology with “ROA suspicion” motive. These consultation requests were cited from the Rheumatology Service within Before the protocol was established, its functioning was communicated as a face-to-face clinical session: by 2 rheumatologists in a Health Centre (HC) and by 1 PCP in the rest of the HC in the area. A poster was edited and published, exposing criteria and referral method for PCP‘s offices. Results: During the first 6 months 33 patients were correctly referred. 78.8% were women and the average age was 49 years old. 48.8% (16 patients) were diagnosed with some inflammatory arthropathy: 31.5% were RA (5 cases); other diagnoses were arthropathy due to microcrystals deposit (2), overlap SLE/RA (1), MCTD(1), psoriatic arthritis (1), spondyloarthritis associated with IBD (1) or inflammatory arthralgia associated with retroperitoneal fibrosis (1). 12% (4 patients) were diagnosed with hands incipient osteoarthritis and 33.8% (12 patients) with arthralgias without data on inflammatory pathology. One patient missed her follow-up. The median time from symptom onset to Rheumatology assessment was 90 days in all patients; in the inflammatory pathologies subgroup, 68.8% was assessed in Conclusion: In our experience, the establishment of a specific protocol in collaboration with Primary Care for the preferential referral of patients with suspected recent onset arthritis, obtained diagnoses not only for patients with rheumatoid arthritis, but also for other systemic autoimmune diseases in early stages, as well as early treatment initiation ( Disclosure of Interests: Consuelo Ramos Giraldez Speakers bureau: Sanofi, Maria Espinosa: None declared, Carolina Merino Argumanez: None declared, Patricia Fernandez Crespo: None declared, Olga Rusinovich: None declared, Fernando Leon Vazquez: None declared, Jose Luis Andreu Sanchez: None declared, Carmen Barbadillo Mateos: None declared

Background Primary Sjogren’s syndrome (pSS) is a systemic autoimmune disease characterized by lymphocytic infiltration of the exocrine glands. Among the extraglandular manifestations, digestive involvement (DI) is frequent, and may condition the quality of life of these patients. There are few studies that systematically analyze gastrointestinal involvement in pSS. Objectives To describe the prevalence of DI in patients with pSS included in SJOGRENSER Spanish registry and the phenotype of these patients, and to analyze their association with other clinical manifestations, serological markers, activity index and treatments used. Methods Transversal multicenter study that includes all patients of SJOGRENSER registry (patients who meet 2002 pSS classification criteria), a study conducted in 33 units of rheumatology in Spain between 2014-2016, which collected demographic and clinical and serological data (1). Patients were classified according to the presence of DI (that included esophagus, stomach, intestine, liver and pancreas). A descriptive analysis was done, with means and standard deviations, frequencies and proportions. Student t for quantitative variables and Chi2 for qualitative ones were performed to evaluate differences between groups. The association of DI with other variables was analyzed by bivariate and multivariate binomial logistic regression analysis. In the multivariate model all variables with p Results From 437 patients included (95% women, median age of 58 years), 59 (13.5%) had some DI (21 (36%) chronic atrophic gastritis, 12 (20%) esophageal dismotility, 3 (5%) lymphocytic colitis, 23 (39%) other). 54% of patients developed DI at the time of pSS diagnosis or later, and 45% before the diagnosis, with a mean age of 49 years at the onset of pSS symptoms. Patients with DI were older, both at diagnosis, onset of pSS symptoms and inclusion in the cohort, than those without it. There were no differences in the ESSDAI index between both groups. Comparison regarding clinical and serological characteristics is shown in Table 1. Patients with DI had more thyroid involvement and C3 hypocomplementemia. In addition, patients with DI had been treated more frequently with glucocorticoids and immunosuppressants. In the multivariate analysis, DI was significantly associated with older age at diagnosis (OR 1.03 (1.00-1.05); p=.005), more C3 hypocomplementemia (OR 2.40 (1.10-5.26) p=.027) and absence of anti-Ro antibodies (OR 0.33 (0.12-0.87) p=.025). Conclusion In patients with pSS from the SJOGRENSER cohort, the prevalence of digestive involvement is 13.5%. These patients are older at diagnosis, have more C3 hypocomplementemia and negative anti-Ro antibodies. These patients need more frequently glucocorticoids and immunosuppressants, suggesting a more severe disease phenotype.

Background Primary Sjogren’s syndrome (pSS) is a systemic autoimmune disease characterized by the involvement of the exocrine glands, mainly salivary and lacrimal glands. Approximately half of patients will experience extraglandular complications throughout their evolution. Objectives To characterize the involvement of the nervous system (NS) in patients with pSS. Methods Multicenter cross-sectional study of a cohort of patients with pSS, constructed by random selection of pSS patients fulfilling the 2002 American-European Consensus Criteria for pSS1 from 33 rheumatology units. Through review of clinical records and interview with patients, demographic, clinical, analytical, therapeutic data and disease activity indexes were collected. Univariate analysis was done by Chi square test, Mann-Whitney U test and Student’s t test. Multivariate analysis was done by linear logistic regression. A p Results 437 patients were included (95% women, median age of 58 years). 65 patients developed NS involvement: 26 patients central NS, 31 peripheral NS and 8 both. Multivariate analysis showed association between NS involvement and atherosclerotic stroke (OR 10.4, 95% CI 2.8-38.5), ear disease (OR 2.1, 95% CI 1.1-4.2) and myopathy (OR 6.5, 95% CI 1.3-31,6). Patients with NS involvement had higher probability of being treated with glucocorticoids (OR 3.3, 95%CI 1.5-7.2) and cyclophosphamide (OR 6.8, 95% CI 1.5-31). Conclusion 15% of patients with pSS develope NS involvement that is associated with atherosclerotic stroke, ear disease and myopathy. Reference [1] Vitali C. et al.

Background: Belimumab is a human IgG1l monoclonal antibody directed against BAFF, a B lymphocyte survival factor. It is indicated as adjuvant treatment in adult patients with active systemic lupus erythematosus (SLE), with positive autoantibodies and with a high degree of activity of the disease despite standard treatment. Objectives: This study aims to describe a sample of patients diagnosed with SLE who received treatment with belimumab in a tertiary hospital. Methods: Retrospective longitudinal unicentric observational study. Clinical records of all patients diagnosed with SLE who had received treatment with belimumab were reviewed. Demographic characteristics, clinical manifestations and reason for belimumab indicaton were collected. Results: The twelve patients included in the sample were women. Median age was 48.5 years (31-70). The most frequent reason for indication of belimumab was uncontrolled arthritis. The average time of treatment with belimumab in the total sample was 27.5 (+/- 26.24) months, with a median of 12 months (4-78). Mean treatment time (cases in which belimumab was discontinued excluded) was 31.25 (+/- 26.98) months with a median of 25 (5-78). The average dose reduction of prednisone after initiation of treatment with belimumab (in patients in which it was considered effective) was 5 mg per day (+/- 5). It should be noted that of the 14 cases, treatment was only discontinued in 4 patients, 2 of which were withdrawn due to ineffectiveness. There were 2 adverse events that required drug withdrawal: neutropenia and urothelial carcinoma. (Table). Conclusion: BLM is a well tolerated drug and effective in clinical practice. Adverse effects leading to drug withdrawal are infrequent.

Objectives: To estimate the incidence of cancer in systemic lupus erythematosus (SLE) patients and to analyze factors associated with cancer differentiating between hormone-sensitive (HS) and non-HS cancers. Methods: Multicenter retrospective study of a cohort of patients included in Spanish Society of Rheumatology Lupus Registry (RELESSER). The first cancer after the diagnosis of SLE, sociodemographic, clinical, activity, cumulative damage, severity, comorbidity, treatments, and refractory disease data were collected. Cancers were classified into HS (prostate, breast, endometrial and ovarian) and non-HS (the rest). Standardized incidence ratio (SIR) was calculated and logistics regression models were constructed to identify factors associated with cancer. Results: We included 3539 patients (90.4% women) with SLE (ACR-97 criteria), of whom 154 had cancer (91% women), and 44 were HS (100% women). The SIR for cancer was 1.37 (95% CI: 1.15-1.59), reaching higher values in women under 65 years [2.38 (95% CI: 1.84-2.91)]. The SIR in women with cancer HS vs. non-HS was 1.02 (95% CI: 0.13-1.91) and 1.93 (95% CI: 0.98-2.89)], respectively. In HS vs. non-HS cancers, age at diagnosis of SLE [Odds ratio (OR) 1.04 (p = 0.002) vs. 1.04 (p = 0.019), respectively] and the evolution time [OR 1.01 (p Conclusion: The incidence of cancer in patients with SLE is increased compared to the Spanish population, specially in younger women. This increase might be due to non-HS cancers. SLE with more cumulative damage and more prescription of ACE inhibitors might associate with non-HS cancers.

Background Systemic sclerosis (SE) is a serious disease of the connective tissue characterized by dysfunction of the microcirculation. Angiogenesis is a complex process regulated by both angiogenic and angiostatic factors. Normally the functions of these factors are under an adequate balance, however, under certain conditions these factors can be induced initiating disorganized angiogenic phenomena. Objectives For the first time, the levels of intraplatelet growth and angiogenic factors (normalized by platelet number and volumen) are described in patients with systemic sclerosis. Methods We included 23 patients with systemic sclerosis (ACR/EULAR) and 16 controls. Patients underwent a platelet-apheresis to obtain platelet-rich plasma (PRP) and platelet-poor plasma (PPP). The samples were subjected to a freeze-thaw process to break the cell membranes and release the platelet content. Subsequently the various factors were measured (VEGF-α, PDGF ββ, HGF, FGF2, G-CSF, MCP-1, IL-1α, IL-1β, IL-8, IL-6, IL-13). Finally, the results were normalized according to the value of the plaquetocrit (number and volumen of platelets). We compared the levels in platelet-rich plasma and in platelet-poor plasma. A cut-off value p Results The mean age of the patients was 52 years ± 9.71, with a duration of the disease of 8 years, 74% were patients with limited SE, 70% of the patients had pulmonary involvement. Both patientes and controls, the TFG-β was 12 times more concentrated in PRP than in PPP (p Conclusion The levels of VEGF-α (intraplatelet) are lower in patients with SE vrs controls (p Reference [1] Choi JJ, et al.

Background: In the last years multiple genetic variants have been associated with autoimmune disease (AD) risk. However, much less is known on the association with important environmental factors like diet. Objectives: The objective of the present study is to characterize the dietary patterns of six prevalent ADs, including rheumatoid arthritis (RA), psoriatic arthritis (PsA) and systemic lupus erythematosus (SLE). Methods: A cross-sectional cohort of 11,621 individuals from Spain encompassing 1,949 RA, 2,186 psoriasis (PS), 1,437 PsA, 699 SLE, 1,415 ulcerative colitis (UC), 1,952 Crohn’s disease (CD) and 1,983 healthy controls, was recruited by the IMID-Consortium. The weekly consumption frequency of main food categories was recorded, together with drinking habits and smoking status. Multivariate linear models were used to test for association while adjusting for confounders. Results: Patients with AD targeting the digestive system showed the largest differences in comparison to controls. In the rheumatic ADs several food categories were also found to be consumed differently compared to controls. SLE had a high consumption of sweets and pastries, and RA ate more fruit and bread/wholegrain foods and less meat and cold cuts compared to controls. In PsA the dietary pattern differences with controls where milder, and non-overlapping with psoriasis. Disease activity was significantly associated with specific food categories in CD, UC and PS, mildly in RA and SLE, and PsA showed no association. High smoking cessation rates were observed in UC, CD and SLE, but not in Ps, RA and PsA. Tea/coffee and alcohol consumption was low in all ADs compared to controls. Conclusion: Our results show previously unreported associations with dietary habits in rheumatic ADs.

Objectives. This article estimates the frequency of polyautoimmunity and associated factors in a large retrospective cohort of patients with SLE. Methods. RELESSER (Spanish Society of Rheumatology Lupus Registry) is a nationwide multicentre, hospital-based registry of SLE patients. This is a cross-sectional study. The main variable was polyautoimmunity, which was defined as the co-occurrence of SLE and another autoimmune disease, such as autoimmune thyroiditis, RA, scleroderma, inflammatory myopathy and MCTD. We also recorded the presence of multiple autoimmune syndrome, secondary SS, secondary APS and a family history of autoimmune disease. Multiple logistic regression analysis was performed to investigate possible risk factors for polyautoimmunity. Results. Of the 3679 patients who fulfilled the criteria for SLE, 502 (13.6%) had polyautoimmunity. The most frequent types were autoimmune thyroiditis (7.9%), other systemic autoimmune diseases (6.2%), secondary SS (14.1%) and secondary APS (13.7%). Multiple autoimmune syndrome accounted for 10.2% of all cases of polyautoimmunity. A family history was recorded in 11.8%. According to the multivariate analysis, the factors associated with polyautoimmunity were female sex [odds ratio (95% CI), 1.72 (1.07, 2.72)], RP [1.63 (1.29, 2.05)], interstitial lung disease [3.35 (1.84, 6.01)], Jaccoud arthropathy [1.92 (1.40, 2.63)], anti-Ro/SSA and/or anti-La/SSB autoantibodies [2.03 (1.55, 2.67)], anti-RNP antibodies [1.48 (1.16, 1.90)], MTX [1.67 (1.26, 2.18)] and antimalarial drugs [0.50 (0.38, 0.67)]. Conclusion. Patients with SLE frequently present polyautoimmunity. We observed clinical and analytical characteristics associated with polyautoimmunity. Our finding that antimalarial drugs protected against polyautoimmunity should be verified in future studies., The RELESSER Registry was partially funded by GlaxoSmithKline (GSK), Roche, Union Chimique Belge (UCB), Lilly and Novartis.

Background The clinical coexistence of Systemic Lupus Erythematosus (SLE) and Sjogrens Syndrome (SS) was recognized in 1959. The prevalence of SS among patients with SLE varies considerably among the published studies (10%–30%). There is still controversy as to whether or not SLE patients with overlapping SS have a distinct and significantly milder lupus. To address the clinical and serologic features of SLE and differences from SLE that occurs in overlap with SS. Methods This is a multicenter, descriptive, cross-sectional study of 3575 patients from the Spanish Society for Rheumatology Lupus Registry (RELESSER). Unselected SLE patients from 45 Rheumatology Departments across Spain were evaluated for the presence of overlapping SS using the American-European consensus criteria. Cumulative clinical data were collected at the moment of the last assessment. Clinical and laboratory parameters in SLE patients with SS (SLEwSS) were compared with those in SLE patients without SS (SLEwoSS). Results SS was identified in 516 SLE patients (14.4%). Compared with the SLEwoSS group, patients with SLEwSS were significantly older, had a higher frequency of mucocutaneous manifestations, Raynauds phenomenon, peripheral neuropathy, anti-Ro/SSA, anti-La/SSB, neoplasia, and older age at death, but had a significantly lower frequency of renal involvement, thrombocytopenia, anti-dsDNA, anti-2-GPI IgM and complement consumption. Both groups displayed a clinically similar presentation of lymphadenopathy, systemic vasculitis, serositis, damage accrual, mortality, musculoskeletal and CNS manifestations. Conclusions SLEwSS appears to constitute a subgroup of SLE patients with distinct clinical and serologic features, in whom SS is expressed as an overlapping entity. A particular cluster of clinical variables, namely, mucocutaneous manifestations, Raynauds phenomenon, peripheral neuropathy, renal involvement and thrombocytopenia, was found to be important overall for discriminating SLE patients with or without SS. SLEwSS patients constitute a subgroup of patients with SLE characterized by milder lupus: older age at death, similar rates of mortality and SLICC-ACR damage index, less renal and immunological manifestations.

Continuous monitoring of the tree water status will enhance irrigation performance, particularly when applying deficit schedules. The olive tree is a highly drought-resistant species and management of the water stress could increase water savings. Trunk diameter fluctuations can be displayed as daily curves representing the shrinkage and swelling, and can provide information about tree water status. In olive trees, trunk growth rate (TGR) is the most useful indicator, but the daily variability reduced the commercial applications. Recently, weekly frequencies of TGR values were associated to the water status in one seasonal experiment. The aim of this work is to study the seasonal pattern and the interannual variations of these parameters in order to integrate them in an irrigation scheduling tool. The experiment was performed during two consecutive seasons (2018 and 2019) in a superhigh density mature olive orchard at Carmona (Seville, Spain). Three different irrigation scheduling treatments were considered in a randomized complete block design. The control treatment was fully irrigated with 150–175% crop evapotranspiration (ETc) in order to ensure an optimum water status. Regulated deficit irrigation-1 (RDI-1) was scheduled using only TGR data provided through the continuous measurements from a dendrometer. In this treatment, water stress conditions were controlled during the pit hardening period. RDI-2 was similar to RDI-1, but with a more severe water stress conditions during pit hardening and a maximum seasonal amount of water that limited rehydration. Water stress was greater during the 2019 season than the 2018 season, according to the midday stem water potential (SWP). Weekly frequencies of TGR values lower than − 0.3 mm day− 1 (Severe FR) and values between − 0.1 and 0.3 mm day− 1 (Good FR) described the water status pattern in the three treatments for both seasons. Only under severe water stress conditions (SWP more negative than − 4 MPa) the values of these frequencies did not identify accurately the water status. However, the use of weekly frequencies of values greater than 0.3 mm day− 1 (Alert FR) and the pattern of these Severe FR and Good FR themselves identified such conditions. The use of these three weekly frequencies (Severe, Good and Alert (SGA) approach) are suggested for continuous deficit irrigation scheduling in olive trees.

Objective To validate the 2013 ACR/EULAR classification criteria for systemic sclerosis (SSc) in patients from a capillaroscopy clinic. Methods All patients attended in a capillaroscopy clinic were included. Sociodemographic and SSc-related variables were collected. Using as gold standard for SSc the clinical judgement, the performance (sensitivity, specificity, predictive values, and likelihood ratios) of the 2013 ACR/EULAR criteria were analyzed. Receiver operating characteristic (ROC) curve and the area under the curve (AUC) were calculated for the global score and individual items, and the best cutoffs were obtained. Results We included 327 patients (84% women, mean age at capillaroscopy 48 years). Main reasons for capillaroscopy referral were Raynaud's phenomenon (39%) and SSc evaluation (27%). The most frequent final clinical diagnosis were SSc (32.4%) and primary Raynaud's phenomenon (25.7%). The 2013 ACR/EULAR SSc classification criteria were met by 116 patients (35.5%). Sensitivity and specificity of the new criteria were 98.1% and 94.6%, respectively, and positive and negative predictive values were 89.7% and 99.1%. The individual variables with the best sensitivity were Raynaud's phenomenon (99.1%) and abnormal nailfold capillaries (81.1%). All the individual variables, except Raynaud's phenomenon, puffy fingers and sclerodactily showed high specificity values, over 90%. The best cutoffs of the total score were ≥8, ≥9, and ≥10, and the AUC=0.993. Conclusions We validated the new ACR/EULAR classification criteria for SSc in unselected patients from a capillaroscopy clinic. Global score and individual items included in the new criteria show high diagnostic accuracy and discriminatory capacity.

Objective To describe the objectives and methods of the Spanish Society of Rheumatology primary Sjogren syndrome (pSS) registry (SJOGREN-SER). Methods This is a multicenter descriptive transversal study of a cohort of pSS patients fulfilling European/American consensus criteria collected from Rheumatology clinics all over Spain. Patients were included by randomisation from an anonymised list provided by every department. Data were collected by reviewing clinical records and an interviewing the patients. Two hundred and ninety eight variables were investigated: epidemiological, clinical, serological characteristics, treatments and complications. Informed consent was obtained and local ethics committees approved the study. Variables were analyzed by descriptive statistical methods, using means, medians, and rates, with their deviations and interquartile ranges (p25–p75). Results A total of 3 rheumatology departments participated in the registry. A total of 437 patients were included. And 95% of them were women, with a median age of 58. Median age at pSS's diagnosis was 50 years. Dryness symptoms (95%) were the most frequent complaint and anti-Ro/SS-A were present in 94% of the cases. Only 27% of the patients fulfilled the new 2012 SICCA-ACR classification criteria. Conclusions SJOGREN-SER has been designed in order to characterize a representative pSS Spanish cohort, in clinical daily practice, to analyze the magnitude and distribution of its manifestations, activity, accumulated damage and therapeutic management of the disease. This will allow broadening the knowledge of this disease and plan strategies of action in pSS.

Objectives:Primary Sjögren´s Syndrome (pSS) is characterized by hyperactivity of the B cell, with the consequent production of autoantibodies. The presence of anti-Ro and anti-La has been associated with extraglandular manifestations and lymphoma development. The aim of this study is to evaluate the frequency of different serological profiles in patients of SJOGRENSER registry and to assess whether the combination of antibodies and serological markers are associated with the development of systemic disease and the systemic illness and/or the development of systemic disease and complications.Methods:SJOGRENSER is a transversal multicenter study with pSS patients (patients who meet 2002 pSS classification criteria); it is collected demographic, clinical, serological data and the activity index: ESSDAI and ESSPRI. It was established three serological profiles: 1. ANA/Ro+ with La/RF-; 2. ANA/Ro/La+ with RF-; 3. ANA/Ro/La/RF+. A descriptive analysis was done, with means and standard deviations, frequencies and proportions. Student t for quantitative variables and Chi2 for qualitative ones were performed to evaluate differences between groups, it was considered a p Results:Four hundred and thirty-seven patients were included, the most frequent serological patterns observed were: ANA/Ro/La/RF+ 221 patients (50.5%), ANA/Ro/La+ 61 patients (13.9%) and ANA/Ro+ 60 patients(13.7%). There were only two patients with ANA/La +. The ESSDAI score was significantly associated with the profile ANA/Ro/La/RF+ (6 vs 4, p=0.007) and the group with the ANA/Ro/La+ profile reached an ESSDAITable 1.Serological markers associated with the development of systemic diseaseInvolvementProfile 1ANA +Anti-Ro +Anti-La -RF –n=60N° (%)Profile 2ANA +Anti-Ro +Anti-La +RF –n= 61N° (%)Profile3ANA +Anti-Ro +Anti-La +RF +n= 221N°(%)pESSDAI index4460.007ESSDAI44 (73.3)48 (78.7)139 (63.2)0.043ESSPRI index6.15.35.00.007Constitutional syndrome5 (8.3)9 (14.8)51 (23.1)0.023Lymphadenopathy8 (13.3)9 (14.8)37 (16.7)0.790Glandular14 (23.3)16 (26.2)87 (39.4)0.024Articular49 (81.7)40 (65.6)187 (84.6)0.004Lung3 (5.0)4 (6.6)29 (13.2)0.100Kidney0 (0)5 (8.2)31 (14.1)0.006Peripheral nervous system5 (8.3)6 (9.8)18 (8.2)0.918Central nervous system4 (6.7)7 (11.5)13 (5.9)0.320Hematological24 (40.0)26 (42.6)147 (66.5)Biologic5 (8.3)4 (6.6)26 (11.8)0.428Lymphoma1 (1.7)2 (3.3)3 (1.4)0.598In contrast to the ESSPRI index was lower significantly associated with the profile ANA/Ro/La/RF+ and higher in the ANA/Ro+ (5 vs 6.1, p=0.007). The presence of antiLa and/or RF to the profile ANA/Ro+ rises the percentage of patients with constitutional syndrome, glandular, kidney and hematological affectation with statistically significant differences. The percentage of patients with articular involvement it was similar in the profiles ANA/Ro+ and ANA/Ro/La/RF +.The multinomial analysis showed that the profile ANA/Ro/La/RF+ was associated with higher ESSDAI values (OR=1.09 (1.01-1.17)). The hematological involvement was associated with the profiles ANA/Ro/La/FR+ (OR= 2.76 (1.46-5.22)). Higher scoring of ESSPRI was associated with the profile ANA/Ro+ (OR=0.79 (0.69-0.91)).Conclusion:The most frequent serological profile was ANA/Ro/La/RF+ and it was associated with higher ESSDAI score. The presence of antiLa and/or RF with an ANA/Ro+ increased the presence of systemic involvement. The ANA/Ro+ profile was associated with a higher level of ESSPRI.Disclosure of Interests:None declared

Objective The aim of this study was to compare the functional results of 2 different procedure types, medical or surgical used in treating native joint septic arthritis. Methods In this cohort study, we reviewed the clinical registries of patients admitted to a single third-level hospital with the diagnosis of septic arthritis during the period of January 1, 2008, to January 31, 2016. Results A total of 63 cases of septic arthritis were identified in which the initial approach for 49 patients was medical (arthrocentesis), whereas the initial approach for 14 patients was surgical (arthroscopy or arthrotomy). Of the 49 patients who received initial medical treatment (IMT), 15 patients (30%) later required surgical treatment because of poor progress. The median age of the patients was 60 (SD, 18) years. The group who received IMT were older than those who received initial surgical treatment (median, 64 years [interquartile range {IQR}, 54–76 years], vs. 48 years [IQR, 30–60 years]). There was a larger percentage of male patients in the surgical group (78% vs. 42% [p = 0.018]). Thirty percent of the medical group had been receiving corticosteroid treatment (p = 0.018). Results of complete recovery of joint functionality showed no significant differences after 1 year (68% with MT vs. 67% with ST, p = 0.91). Both groups had similar symptom duration until diagnosis, duration of antibiotic therapy (median, 30 days [IQR, 28–49 days], vs. 29.5 days [IQR, 27–49] days), and mortality rate (3 in the medical group). Conclusions The results of the study show that initial surgical treatment in patients with native joint septic arthritis is not superior to IMT. However, half of the patients with shoulder and hip infections treated with IMT eventually required surgical intervention, suggesting that perhaps this should be the preferred initial approach in these cases.

Topaz is an aluminosilicate mineral phase stable in the hydrothermally altered pegmatitic rocks and also in subducted sedimentary lithologies. In nature, topaz often exhibits solid solution between fluorine and hydrous end members. We investigated elasticity of naturally occurring single crystal topaz (Al2SiO4F1.42(OH)0.58) using Resonant Ultrasound Spectroscopy. We also explored the temperature dependence of the full elastic constant tensor. We find that among the various minerals stable in the Al2O3-SiO2-H2O ternary system, topaz exhibits moderate elastic anisotropy. As a function of temperature, the sound velocity of topaz decreases with $$\frac{{\boldsymbol{d}}{{\boldsymbol{V}}}_{{\boldsymbol{P}}}}{{\boldsymbol{d}}{\boldsymbol{T}}}$$ d V P d T and $$\frac{{\boldsymbol{d}}{{\boldsymbol{V}}}_{{\boldsymbol{S}}}}{{\boldsymbol{d}}{\boldsymbol{T}}}$$ d V S d T being −3.10 and −2.30 × 10−4 km/s/K. The elasticity and sound velocity of topaz also vary as a function of OH and F content. The effect of composition ($${{\boldsymbol{x}}}_{{\boldsymbol{O}}{\boldsymbol{H}}}$$ x O H ) on the velocity is equally important as that of the effect of temperature. We also note that the Debye temperature ($${{\boldsymbol{\Theta }}}_{{\boldsymbol{D}}}$$ Θ D ) of topaz at room temperature condition is 910 K and decreases at higher temperature. The Debye temperature shows positive correlation with density of the mineral phases in the Al2O3-SiO2-H2O ternary system.

Carpal tunnel syndrome (CTS) is the most common peripheral mononeuropathy and thus is frequently encountered by general practitioners (GPs). The aim of this study is to investigate the referral pattern of GPs with regard to electrodiagnostic (EDX) testing for suspected CTS prior to hand surgery consultation, as well as to investigate the results of EDX testing for suspected CTS when requested by GPs prior to evaluation by a hand surgeon.We retrospectively reviewed patients referred to our hand surgery clinic over a consecutive 2-year period for suspected CTS.A total of 403 patients were referred to our hand surgery clinic from January 1, 2016, to December 31, 2017. Of the 403, 295 (73.2%) were referred by GPs. GPs obtained prereferral EDX testing in 198 (67.1%) of these patients. EDX testing confirmed their diagnosis in 177 patients (89.4%). There were 21 patients (10.6%) identified with normal EDX testing and a more likely diagnosis reached based on clinical examination.GPs make up the majority of our referrals for CTS, and they obtain EDX testing prior to consultation in two-thirds of referrals. GPs appear to accurately utilize EDX testing to confirm their diagnosis prior to referral and have a low rate of normal testing where symptoms are more readily explained by an alternative diagnosis.

The aim of this study is to describe the findings of a protocolised odontological evaluation of patients with primary Sjögren's syndrome (pSS) treated in rheumatology units in the Community of Madrid.Multicentric descriptive study in which pSS patients classified according to the American-European consensus of 2002 criteria were included. We collected the demographic, clinical and serological data of each patient. A complete oral examination was performed and salivary flow and the CAOD caries index were collected. The patients completed the visual analogue scale for xerostomia, the Oral Health Impact Profile-14 questionnaire and an oral health questionnaire.Sixty-one patients were recruited. Ninety-eight percent were women and the mean age of the patients was 57 years. Pathological oral signs (unstimulated salivary flow/salivary glands sialography/scintigraphy) were present in 52.5% of the patients, anti-Ro/anti-La were positive in 90.2%. Ninety-two percent of the patients reported xerostomia and 61% of the patients suffered from hyposialia. Thirty-five patients presented oral mucosa lesions. CAOD index was 16.97±7.93 and visual analogue scale for xerostomia was 46.69±14.43. The results of the OHIP-14 questionnaire were 23.13±14.16. Patients with pathological oral signs obtained a significantly higher Oral Health Impact Profile-14 score (P=.03). We also found that patients with peripheral nervous system involvement obtained a significantly higher Oral Health Impact Profile-14 score (P=.001) CONCLUSIONS: The presence of xerostomia in this cohort of pSS patients was high and hyposialia was present in 61% of the patients. Oral lesions appeared in more than half of the subjects. Oral health had a negative impact on the quality of life of patients with pSS, being higher in those with pathological objective oral signs and in those with peripheral nervous system involvement.

Background Belimumab is a human monoclonal antibody that inhibits B-cell activating factor shown to be efficacious in systemic lupus erythematosus. In other B cell mediated autoinmune disease such as primary Sjogren’s syndrome(pSS) the efficacy is unclear. Objectives To evaluate the efficacy of belimumab in patients with pSS. Methods A systematic literature review was perfomed (EMBASE, MEDLINE and Cochrane) as part of the Spanish Rheumatology Society’s Recommendations for the Use of Biological Therapies in Primary Sjogren’s Syndrome. Inclusion criteria was defined as: Population: patients with pSS according to American-European Consensus Criteria 2002 Intervention: belimumab; Control: synthetic or biologic DMARDs, corticosteroids, ursodesoxicolic acid or placebo; Outcome: efficacy in dryness, glandular and extraglandular manifestations. Studies with Results 3 articles were included out of 135. All of them published results from the same study1 at different timepoints. The study design was experimental but with a small sample size and no control group or randomization. The article of Mariette et al 20151 evaluated the efficacy and safety of belimumab in 30 patients with systemic activity or early disease until week 28(W28). There was a significant decrease in mean ESSDAI (8.8 to 6.3 p=0.02), ESSPRI (6.4 to 5.6 p=0.02) and VAS for dryness (7.8 to 6.2 p=0.02). Physician’s VAS for disease systemic activity also decreased in 43% as well as parotid inflammation in 76.9% of patients. Also, B cell biomarkers decreased: IgG (21.2 to 18.2 g/L, p=0.02), IgA (3.7 to 3.3 g/L, p=0.04), IgM (1.6 to 1.3 g/L, p The study of De Vita et al 20152 compared results at week 52 (W52) and W28 in 19 patients, of whom 15 had previously responded to treatment. Of these 15 patients 13 maintained response and 3 out of the 4 patients that did not respond achieved primary outcome. The improvement at W52 continued for ESSDAI, glandular inflammation, lympadenopathy and joints. B cell biomarkers remained stable. Overall items conributing to ESSDAI descreased but only physician’s VAS for disease systemic activity was statistically significant (3.2 W28 vs 2.5 W52; p=0.04). The study of Quartuccio et al.3 compared clinical and lab variables of W52 with 12 months of follow up after interrupting belimumab. A significant decrease in ESSDAI in 9 out of 13 patients (3.5±3.7 vs 7.0±5.7; p Conclusions Published evidence to determine the efficacy of belimumab in primary Sjogren is limited and poor. Belimumab seems to be effective to reduce systemic activity, parotid enlargement, dryness, lymphadenopathies, articular manifestation, fatigue and B cell biomarkers.

Background Primary Sjogren’s syndrome (pSS) is characterised by lymphocytic infiltration of exocrine glands and other organs, resulting in dry eye, dry mouth and extraglandular systemic involvement such as pain, mialgia or polyarthralgia, among others. Objectives The aim of the present study is to explore the association of severe or very severe dry eye with extraocular involvement in patients with pSS. Methods SJOGRE-SER registry is a multicenter cross-sectional study of pSS patients fulfilling European/American consensus criteria 2002 from 33 Spanish rheumatology departments. Data were collected by reviewing clinical records and interviewing patients. For the construction of our main variable, “severe/very sever dry eye” (S/VSDE), we used those variables present in our cohort that represented a degree 3–4 of severity (S/VSDE) according to the dry eye TFOS DEWS I classification 2007 (Tear Film and Ocular Surface Society Dry Eye Work-Shop): Schirmer score (≤5 mm/5 min) and/or corneal ulcers and/or use of autologous sera and/or contact lenses and/or Stenon conduit bypass and/or palpebral cleft reduction. First, bivariate logistic regression models were used to identify the effect of each independent variable on S/VSDE. Secondly, multivariate analysis using regression model was used to establish the independent effect of patient characteristics associated with the dependent variable. Results Four hundred and thirty-seven patients were included in SJOGREN-SER registry (female gender 95%; median age 58 (50.02–67.98) years). Mean time of evolution of the disease in the cohort was 8.3 years. ESSDAI mean score was 2 (0–4, P25-P75) in the full registry. Ninety-four per cent of the patients in SJOGREN-SER cohort complained of daily, persistent, troublesome dry eyes, 92% had sensation of sand in the eyes and 16% developed corneal ulcer. In the full cohort Schirmer’s test was performed in 402 patients and was pathological (≤5 mm/5 min) in 371 patients (92%). The use of autologous sera was 14%, contact lenses 2%, Stenon conduit bypass 0.23% and palpebral cleft reduction 0.23%. Three hundred and seventy-eight patients (86.5%) presented S/VSDE; 95% were women, and the median age was years. Mean time of evolution of the disease was 8.51 and ESSDAI mean score was 5. Inflammatory articular involvement was significantly more frequent in patients with S/VSDE (82.5%) than in those without S/VSDE (69.5%) (p=0,028). Inflammatory joint affectation was associated with S/VSDE in the multivariate analysis, OR 2.079 (95% CI, 1.096–3.941). These results were adjusted by sex, age, time of evolution of the disease and ESSDAI score. Conclusions Severe or very severe ocular involvement is associated with the presence of inflammatory joint involvement in patients with pSS. These results suggest that a directed anamnesis including systemic comorbidities, such as the presence of inflammatory joint affectation and dry mouth, in patients with severe dry eye, would be useful to suspect an pSS.

Background Systemic Lupus Erythematosus (SLE) is an autoimmune disease associated with systemic inflammatory processes. Chronic inflammation alters the of the number and type of non-cellular elements, including lipoproteins and glycoproteins. Objectives Here we investigate the plasmatic lipoprotein and glycoprotein profiles associated with SLE. Methods Plasma samples were obtained from 50 healthy control individuals and 50 SLE patients. All patients fulfilled the ACR criteria for classification of SLE. 1H-NMR was used to determine the lipoprotein and glycoprotein profiles from cases and controls. For the lipoprotein profiles, VLDL, LDL, IDL and HDL concentration, lipid composition and particle properties were quantified. The glycoprotein profile was decomposed in four reproducible peak regions LMW, Glyc-B, Glyc-A, Glyc-Lipid and baseline, and quantified for concentration, position and aggregation state. Association analysis to disease was performed using logistic regression fitting for age, gender and body mass index. Classifiers were built using recursive-partition algorithm and classification accuracy was evaluated using receiver operating curves. Results We found a significant perturbation of the lipoprotein profile in SLE patients compared to controls. A statistically significant (P Conclusions SLE is characterized by perturbations of the plasmatic lipoprotein and glycoprotein profiles. The increase of triglyceride VLDL in patients compared to controls, could explain the increased risk for cardiovascular disease observed in SLE. Our results also show that SLE patients have a significantly different glycoprotein profile compared to controls. In both cases, plasmatic 1H-NMR profiling could be a valuable source of informative biomarkers for SLE. Disclosure of Interest None declared

Background Primary Sjogren’s syndrome (SSp) is a systemic autoimmune disease characterised by exocrine gland affectation and multisystem involvement. In addition to the systemic inflammatory affectation, patients with pSS have additional risk factors to develop osteoporosis (OP) and its major complication, osteoporotic fracture. Objectives The aim of the study is to determine the sociodemographic and clinical factors of pSS associated with the presence of OP and osteoporotic fracture in patients with pSS from the SJOGRENSER registry. Methods SJOGRENSER is a descriptive, cross-sectional and multicenter study of patients with pSS classified according to European-American consensus criteria. Patients attended in consultations of 33 Spanish rheumatology services were randomly included. Both the medical history and the medical interview were used to obtain the data. Epidemiological, clinical, serological and complications were collected. The continuous and categorical variables were analysed by means, medians and frequencies, with their respective deviations and interquartile ranges (p25-p75). Bivariate and multivariate analyses were carried out using a binomial logistic regression to study the factors associated with osteoporosis and osteoporotic fracture in pSS. Results In the SJOGRENSER registry, 437 patients were included (95% women, with a median age of 58.63 (50.02–67.98) years). The prevalence of OP in the cohort was 18.54% (81 patientes). The prevalence of OP in men (n=21) was 19%, 2 men in the age group of 51–64 years and 2 in the group of >64 years. Three hundred of the women in the registry were menopausal (76.4%); a total of 67/300 women with menopausia had OP (15%). A total of 37 osteoporotic fractures (8.5%) were recorded in the cohort. Factors associated with OP in women with SSp in the bivariate analysis were: age (60.5% in the group of >64 years, 28% in the group of 51–64 years and 2.6% in the group ≤50 years, p 64 years, OR 20.610 (CI 95% 4.679–90.774, p 64 years, OR 7.674 (95% CI 1.675–35.151, p Conclusions Patients with pSS have a considerable prevalence of osteoporosis and osteoporotic fracture. Age and time of evolution were factors associated with the development of OP, and similarly, age, time of evolution of the disease and ESSDAI were factors associated with the development of fracture in patients with pSS.
