To identify recommendations on the diagnosis and management of rheumatoid arthritis (RA) supported by low recommendation grades, to study the causes of this low grading, and to propose solutions. A group of six rheumatologists, with extensive experience in the development of systematic reviews, reviewed national and international RA recommendations and practice guidelines. They identified all recommendations with a low level of evidence or recommendation grade (levels equivalent to 4, 5, or grades C or D of the Oxford Levels of Evidence), classified them by areas (diagnosis, follow-up, treatment, others), and analyzed plausible causes of low graduation. A Delphi was used to select 10 recommendations where it was most important to obtain quality evidence to support them. Subsequently, actions were proposed to improve evidence and recommendation grading. Fourteen documents were analyzed, in which 192 recommendations with low evidence/grade of recommendation were identified, most of which were on treatment. The two most frequent causes of this low level are the absence of studies and the discrepancy between the wording of the recommendation and the evidence used. Finally, the proposed solution to the critical recommendations is a list of unanswered research questions and possible designs to answer them. We propose to design and promote research that truly supports or rectifies clinical practice and, thus, bridges the gap between existing evidence and critical recommendations.

Objective The difficulty in diagnosis and the spectrum of clinical manifestations that can determine the choice of treatment for primary antiphospholipid syndrome (APS) has fostered the development of recommendations by the Spanish Society of Rheumatology (SER), based on the best possible evidence. These recommendations can serve as a reference for rheumatologists and other specialists involved in the management of APS. Methods A panel of four rheumatologists, a gynaecologist and a haematologist with expertise in APS was created, previously selected by the SER through an open call or based on professional merits. The stages of the work were: identification of the key areas for drafting the document, analysis and synthesis of the scientific evidence (using the Scottish Intercollegiate Guidelines Network [SIGN] levels of evidence) and formulation of recommendations based on this evidence and formal assessment or reasoned judgement techniques (consensus techniques). Results 46 recommendations were drawn up, addressing five main areas: diagnosis and evaluation, measurement of primary thromboprophylaxis, treatment for APS or secondary thromboprophylaxis, treatment for obstetric APS and special situations. These recommendations also include the role of novel oral anticoagulants, the problem of recurrences or the key risk factors identified in these subjects. This document reflects the first 21, referring to the areas of: diagnosis, evaluation and treatment of primary APS. The document provides a table of recommendations and treatment algorithms. Conclusions An update of the SER recommendations on APS is presented. This document corresponds to part I, related to diagnosis, evaluation and treatment. These recommendations are considered tools for decision-making for clinicians, taking into consideration both the decision of the physician experienced in APS and the patient. A part II has also been prepared, which addresses aspects related to obstetric SAF and special situations.

Los resultados permitiran comparar los datos con estudios de otros paises y con el EPISER 2000.

Objectives To develop recommendations for the prevention of infection in adult patients with systemic autoimmune rheumatic diseases (SARD). Methods Clinical research questions relevant to the objective of the document were identified by a panel of experts selected based on their experience in the field. Systematic reviews of the available evidence were conducted, and evidence was graded according to the Scottish Intercollegiate Guidelines Network criteria. Specific recommendations were made. Results Five questions were selected, referring to prevention of infection by Pneumocystis jirovecii with trimethoprim/sulfamethoxazole, primary and secondary prophylactic measures against hepatitis B virus, vaccination against human papillomavirus, vaccination against Streptococcus pneumoniae and vaccination against influenza virus, making a total of 18 recommendations, structured by question, based on the evidence found for the different SARD and/or expert consensus. Conclusions There is enough evidence on the safety and efficacy of vaccinations and other prophylactic measures against the microorganisms reviewed in this document to specifically recommend them for patients with SARD.

Aims Interstitial lung disease (ILD) is frequent in patients with rheumatoid arthritis (RA) and is associated with significant morbidity and mortality. The aim of this review was to identify the different screening methods for ILD in patients with RA. Methods We ran a systematic search in Pubmed, Embase and Cochrane Library up to April 2020 and did a hand search of the references of the retrieved articles. The search was limited to humans and articles published in English, Spanish or French. We selected studies with any design where: (a) the population included adult patients with RA; (b) the intervention was any screening method for ILD; and (c) validity or reliability of the screening method were evaluated, or a screening method was described. Two reviewers independently screened the articles by title and abstract and subsequently extracted the information using a specific data extraction form. Results 25 studies were included with a total of 2593 patients. The most frequently used tool for ILD screening was high resolution computed tomography (HRCT) of the lung. Electronic auscultation, biochemical markers, bronchoalveolar lavage (BAL), pulmonary function tests (PFTs) and lung ultrasonography were also evaluated. Across the different studies, electronic auscultation and lung ultrasonography achieved higher accuracy than PFTs, BAL and biochemical markers. Conclusions HRCT resulted as the most sensitive tool for ILD screening in patients with RA. Given its harmlessness and high sensitivity, lung ultrasonography may become the first-choice tool in the future.

Rheumatoid arthritis (RA) prevalence is believed to be around 1% worldwide, although it varies considerably among different populations. The aim of EPISER2016 study was to estimate the prevalence of RA in the general adult population in Spain. We designed a population-based cross-sectional study. A national survey was conducted between November 2016 and October 2017 involving a probabilistic sample from the general population aged 20 years or older. Subjects were randomly selected for phone screening using a computer-assisted telephone interviewer system. Positive RA screening results were evaluated by a rheumatologist. Cases fulfilled the 1987 ACR and/or the 2010 ACR/EULAR criteria; previous diagnosis established by a rheumatologist and clearly identified in medical records were also accepted regardless of the criteria used. Prevalence estimates with 95% CI were calculated taking into account the design of the sample (weighting based on age, sex, and geographic origin using as a reference the distribution of the population in Spain). 4916 subjects participated in the study and 39 RA cases were confirmed. RA estimated prevalence was 0.82% (95% CI 0.59–1.15). Mean age of RA cases was 60.48 (14.85) years, they were more frequently women (61.5%), from urban areas (74.4%), non-smokers (43.6%), and with a high body mass index (53.8% with overweight). Extrapolating to the population in Spain (approximately 37 million are ≥ 20 years old), it was estimated that there were between 220,000 and 430,000 people aged 20 years or older with RA. No undiagnosed cases were detected, which could be related to the establishment of early arthritis clinics around the country, increasing the rates of diagnosis during early phases of RA.

Objectives Prevalence of SLE varies among studies, being influenced by study design, geographical area and ethnicity. Data about the prevalence of SLE in Spain are scarce. In the EPISER2016 study, promoted by the Spanish Society of Rheumatology, the prevalence estimate of SLE in the general adult population in Spain has been updated and its association with sociodemographic, anthropometric and lifestyle variables has been explored. Methods Population-based multicentre cross-sectional study, with multistage stratified and cluster random sampling. Participants were contacted by telephone to carry out a questionnaire for the screening of SLE. Investigating rheumatologists evaluated positive results (review of medical records and/or telephone interview, with medical visit if needed) to confirm the diagnosis. To calculate the prevalence and its 95% CI, the sample design was taken into account and weighing was calculated considering age, sex and geographic origin. Multivariate logistic regression models were defined to analyse which sociodemographic, anthropometric and lifestyle variables included in the telephone questionnaire were associated with the presence of SLE. Results 4916 subjects aged 20 years or over were included. 16.52% (812/4916) had a positive screening result for SLE. 12 cases of SLE were detected. The estimated prevalence was 0.21% (95% CI: 0.11, 0.40). SLE was more prevalent in the rural municipalities, with an odds ratio (OR) = 4.041 (95% CI: 1.216, 13.424). Conclusion The estimated prevalence of SLE in Spain is higher than that described in most international epidemiological studies, but lower than that observed in ethnic minorities in the United States or the United Kingdom.

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.

Background:Although ideally Recommendations for the management of rheumatoid arthritis (RA) should be supported by the highest level of evidence, many of which are based on “expert opinion”. This means that there are knowledge gaps to which a part of the research efforts in this disease should be directed.Objectives:1.- Analyze the causes of the low level of evidence in some of the recommendations on diagnosis and management of RA in the main published documents2.- Identify the knowledge gaps that justify said low level of evidence3.- Design actions to respond to the knowledge gaps identified.Methods:Qualitative study. A group of six experts in systematic review of the literature was selected. Fourteen documents of national and international recommendations on RA (EULAR, ACR and SER) of the last 5 years were analyzed by a peer review. They selected recommendations with low level of evidence (Oxford 4 and 5) / grade of recommendation (C and D), and classified by areas (diagnosis, monitoring, treatment, others) and then possible causes of low level of evidence were analyzed. These were submitted to a Delphi to select the 10 recommendations in which participants considered it more critical to obtain quality evidence. Subsequently, actions were proposed to improve the levels of evidence in general and, through the PICOS structure (population, intervention, comparator, study design) specific studies were proposed to respond to the issues raised in these 10 recommendationsResults:185 recommendations were found that had a low level of evidence / grade of recommendation, most related to the treatment of RA. The two most frequent causes of this low level of evidence and / or the degree of recommendation were the absence of studies and an incorrect classification of the level of evidence and / or degree of recommendation. In addition, other reasons and methodological barriers were found for which nine critical recommendations were finally selected for which new PICOs were developed with which to propose targeted research projectsConclusion:It is necessary to improve the methodological approach in the RA recommendations guidelines to correct errors and fill gaps with appropriate studies.Table 1.Actions to increase the level of evidence / recommendation.#Action1Prioritization of research towards knowledge gaps with the design and development of specific studies2Increase knowledge of experts in the methodology of consensus documents (including RSL, formulation of recommendations, etc.)3Supervision of the entire process by expert methodologists, to ensure a correct allocation of the levels of evidence and degree of recommendation4Review and select those topics that are really of interest and should be reviewed and can be answered5Expert opinion should never become a recommendation, but will be included in the text that accompanies that recommendation.6Clear syntax will be used and short recommendations will be made7Establishment and application of homogeneous criteria to formulate recommendationsKey words: Rheumatoid arthritis, recommendations, data gapsDisclosure of Interests:gloria candelas: None declared, Lucía Silva-Fernández: None declared, Maria Montoro Employee of: Pfizer employee, Abad Hernández: None declared, Jose Ramón Maneiro: None declared, Virginia Villaverde: None declared, Loreto Carmona Grant/research support from: Novartis Farmaceutica, SA, Pfizer, S.L.U., Merck Sharp & Dohme España, S.A., Roche Farma, S.A, Sanofi Aventis, AbbVie Spain, S.L.U., and Laboratorios Gebro Pharma, SA (All trhough institution), Estíbaliz Loza Grant/research support from: Roche, Pfizer, Abbvie, MSD, Novartis, Gebro, Adacap, Astellas, BMS, Lylly, Sanofi, Eisai, Leo, Sobi, Susana Gómez Employee of: Pfizer employee, Monica Valderrama Consultant of: Pfizer employee, Ana Ortiz: None declared

ObjectivesSince the 2007 recommendations for the management of early arthritis have been presented, considerable research has been published in the field of early arthritis, mandating an update of the 2007 European League Against Rheumatism (EULAR) recommendations for management of early arthritis.MethodsIn accordance with the 2014 EULAR Standardised Operating Procedures, the expert committee pursued an approach that was based on evidence in the literature and on expert opinion. The committee involved 20 rheumatologists, 2 patients and 1 healthcare professional representing 12 European countries. The group defined the focus of the expert committee and target population, formulated a definition of ‘management’ and selected the research questions. A systematic literature research (SLR) was performed by two fellows with the help of a skilled librarian. A set of draft recommendations was proposed on the basis of the research questions and the results of the SLR. For each recommendation, the categories of evidence were identified, the strength of recommendations was derived and the level of agreement was determined through a voting process.ResultsThe updated recommendations comprise 3 overarching principles and 12 recommendations for managing early arthritis. The selected statements involve the recognition of arthritis, referral, diagnosis, prognostication, treatment (information, education, pharmacological and non-pharmacological interventions), monitoring and strategy. Eighteen items were identified as relevant for future research.ConclusionsThese recommendations provide rheumatologists, general practitioners, healthcare professionals, patients and other stakeholders with an updated EULAR consensus on the entire management of early arthritis.

Objective Relapses and failure are frequent in systemic vasculitis (SV) patients. Biological agents have been prescribed as rescue therapies. The aim of this systematic review is to analyze the current evidence on the therapeutic use of biological agents for SV. Methods MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched up to the end of April 2013. Systematic reviews and meta-analysis, clinical trials, cohort studies, and case series with >3 patients were included. Independent article review and study quality assessment was done by 2 investigators with consensus resolution of discrepancies. Results Of 3447 citations, abstracts, and hand-searched studies screened, 90 were included. Most of the studies included ANCA-associated vasculitis (AAV) patients and only a few included large vessel vasculitis (LVV) patients. Rituximab was the most used agent, having demonstrated efficacy for remission induction in patients with AAV. A number of studies used different anti-TNFα agents with contrasting results. A few uncontrolled studies on the use of abatacept, alemtuzumab, mepolizumab, and tocilizumab were found. Conclusion Current evidence on the use of biological therapies for SV is mainly based on uncontrolled, observational data. Rituximab is not inferior to cyclophosphamide for remission induction in AAV and might be superior in relapsing disease. Infliximab and adalimumab are effective as steroid-sparing agents. Etanercept is not effective to maintain remission in patients with granulomatosis with polyangiitis, and serious adverse events have been reported. For LVV, both infliximab and etanercept had a role as steroid-sparing agents, and tocilizumab might be effective also for remission induction in LVV.

Objectives: To explore the influence of tumour necrosis factor inhibitors (TNFi) therapy and rituximab upon the incidence of cancer in patients with rheumatoid arthritis (RA) and prior malignancy.Methods: The study population comprised RA subjects with a prior malignancy reported to the UK national cancer registers, recruited to the British Society for Rheumatology Biologics Register from 2001 to 2013. We compared rates of first incident malignancy in a TNFi-cohort, rituximab-cohort and synthetic disease-modifying antirheumatic drugs (sDMARD) cohort. Results: We identified 425 patients with a prior malignancy from 18,000 RA patients in the study. Of these, 101 patients developed a new malignancy. The rates of incident malignancy were 33.3 events/1,000 person-years in the TNFi cohort, 24.7 events/1,000 person-years in the rituximab cohort and 53.8 events/1,000 person-years in the sDMARD cohort. The age- and gender-adjusted hazard ratio was 0.55 (95% confidence interval 0.35-0.86) for the TNFi cohort and 0.43 (95% confidence interval 0.10 – 1.80)) for the rituximab cohort in comparison with the sDMARDs cohort. The 17.0% of patients in the sDMARDs cohort had a recurrence of the same cancer in comparison with the 12.8% and the 4.3% in the TNFi and rituximab cohorts respectively.Conclusions: Although numbers are still low, it seems that patients with RA and prior malignancy selected to receive either a TNFi or rituximab in the UK do not have an increased risk of future incident malignancy.

Objective To provide a reference to rheumatologists and other physicians involved in the treatment of systemic lupus erythematosus (SLE) who are using, or about to use biologic therapies. Methods Recommendations were developed following a nominal group methodology and based on systematic reviews. The level of evidence and degree of recommendation were classified according to a model proposed by the Center for Evidence Based Medicine at Oxford. The level of agreement was established through a Delphi technique. Results We have produced recommendations on the use of belimumab, the only biological agent with approved indications for SLE, and other biological agents without an indication for SLE. The objective of treatment is to achieve a complete clinical response, taken as the absence of perceived or evident disease activity. Nuances regarding the use of biologic therapies in SLE were reviewed as well, such as the evaluation that should be performed prior to administration and the follow up of patients undergoing these therapies. Conclusions We present the SER recommendations for the use of biological therapies in patients with SLE.

Objetivo Elaborar unas recomendaciones que sirvan de referencia a los reumatologos y otros profesionales implicados en el tratamiento del lupus eritematoso sistemico (LES) que vayan a utilizar o consideren la utilizacion de terapias biologicas en su manejo. Metodos Las recomendaciones se emitieron siguiendo la metodologia de grupos nominales y basadas en revisiones sistematicas. El nivel de evidencia y el grado de recomendacion se clasificaron segun el modelo del Center for Evidence Based Medicine de Oxford y el grado de acuerdo se extrajo por tecnica Delphi. Resultados Se realizan recomendaciones sobre el uso de belimumab, actualmente unica terapia biologica con aprobacion para el tratamiento del LES, y otras terapias biologicas sin indicacion aprobada en LES. El objetivo del tratamiento es la respuesta clinica completa, entendida como la ausencia de actividad clinica percibida o constatable. Se matiza el uso de terapias biologicas en LES y cual debe ser la evaluacion previa y la vigilancia del paciente que recibe estos farmacos. Conclusiones Se presentan las recomendaciones SER sobre el uso de terapias biologicas en el LES.

Corticosteroids are a mainstay in the therapy of rheumatoid arthritis (RA). In recent years, a number of high-quality controlled clinical trials have shown their effect as a disease-modifying anti-rheumatic drug (DMARD) and a favorable safety profile in recent-onset RA. Despite this, they are more frequently used as bridge therapy while other DMARDs initiate their action than as true disease-modifying agents. Low-dose corticosteroid use during the first two years of disease slows radiologic damage and reduces the need of biologic therapy aimed at reaching a state of clinical remission in recent-onset RA. Thus, their systematic use in this clinical scenario should be considered.

Los glucocorticoides son un componente fundamental en el tratamiento de la artritis reumatoide (AR). En los ultimos anos, numerosos ensayos clinicos controlados de alta calidad metodologica han demostrado su accion como farmaco antirreumatico modificador de enfermedad (FAME) y un favorable perfil de seguridad en la AR de reciente comienzo. No obstante, es frecuente que se utilicen mas como terapia puente hasta que otros FAME comienzan a actuar que como autenticos agentes modificadores de enfermedad. Los glucocorticoides a dosis bajas durante los 2 primeros anos de la enfermedad frenan el deterioro radiologico y reducen la necesidad de usar agentes biologicos para conseguir la remision clinica en la AR de inicio por lo que se deberia valorar su utilizacion sistematica en este contexto clinico

a b s t r a c t Purpose: To determine the efficacy and safety of denosumab in osteoporosis. Methods: A systematic search was performed in MEDLINE, EMBASE, and The Cochrane Central Register of Controlled Trials (1950 to July 2010), meeting abstracts (2009-2010), trial registries, and reference lists. The selection criteria were as follows: (population) osteoporosis patients of any age; (intervention) treatment with denosumab; (outcome) efficacy and safety; (study design) randomized clinical trials (RCTs); no language restrictions. Two reviewers independently screened titles and abstracts and subse- quently extracted data from the selected studies including quality items, and on outcomes of interest. A meta-analysis was performed for safety issues. Results: A total of 25 studies were included. Denosumab reduces the risk of new radiographic vertebral fracture in a 68% compared with placebo (p < 0.001) and increases bone mineral density (BMD) at lumbar spine, total hip, and one-third radius more than alendronate and placebo. A single subcutaneous dose of denosumab resulted in a dose-dependent, rapid, profound, and sustained decrease bone turnover markers (BTMs). Denosumab was in general well tolerated. A meta-analysis has shown an increase in the incidence of urinary infections (p = 0.012) and eczema (p < 0.001) in the patients treated with denosumab. Meta-analysis of efficacy was complicated due to the study features. Conclusions: Denosumab given subcutaneously twice yearly is associated with a reduction in the risk of vertebral, nonvertebral, and hip fractures in women with osteoporosis. Denosumab is associated with greater and sustained increases in BMD and reductions in BTMs compared with placebo and/or alendronate and with a risk of urinary infections and eczema.

The aim of this work was to assess the variability in the use of health-care resources, based on the number of visits to rheumatology departments by rheumatoid arthritis patients, in Spain, and its association with patient, physician and center characteristics. The sample consisted of patient records of men and women (aged 16 or older), with a clinical diagnosis of RA, who met the American Rheumatism Association 1987 revised criteria and who had been treated in a rheumatology department at a Spanish hospital with at least one visit to a rheumatologist during the two years preceding the date of the study. To analyze which variables were independently associated with the number of consultations, those with a statistically significant result in the bivariate analysis, or which were clinically relevant or deemed confounders, were used in the construction of a linear regression model. The records of 1188 RA patients were studied. The linear regression model explained the 26.67 % of the variability in the number of visits. The number of csDMARDs prescribed, the administration of biological therapy, corticoid prescription, the presence of nursing consultation, mean time to first visit in the department and attended population showed a positive significant association, while the presence of telephone consultation, distance from the hospital to the patient´s residence (≥20 km) and drug monitoring by rheumatology department + primary care physician or by other specialists were negatively associated with the number of consultations. We observed a high variability in the number of visits, which remains partially unexplained even after taking into account individual, physician and center characteristics.

Objectives. To identify patterns (clusters) of damage manifestations within a large cohort of SLE patients and evaluate the potential association of these clusters with a higher risk of mortality. Methods. This is a multicentre, descriptive, cross-sectional study of a cohort of 3656 SLE patients from the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics Damage Index. Using cluster analysis, groups of patients with similar patterns of damage manifestations were identified. Then, overall clusters were compared as well as the subgroup of patients within every cluster with disease duration shorter than 5 years. Results. Three damage clusters were identified. Cluster (80.6% of patients) presented a lower amount of individuals with damage (23.2 vs 10096 in clusters 2 and 3. P < 0.001). Cluster 2 (11.4% of patients) was characterized by musculoskeletal damage in all patients. Cluster 3 0.096 of patients) was the only group with cardiovascular damage, and this was present in all patients. The overall mortality rate of patients in clusters 2 and 3 was higher than that in cluster 1 (P < 0.001 for both comparisons) and in patients with disease duration shorter than 5 years as well. Conclusion. In a large cohort of SLE patients, cardiovascular and musculoskeletal damage manifestations were the two dominant forms of damage to sort patients into clinically meaningful clusters. Both in early and late stages of the disease, there was a significant association of these clusters with an increased risk of mortality. Physicians should pay special attention to the early prevention of damage in these two systems.

OBJECTIVES: To estimate the incidence of severe infection and investigate the associated factors and clinical impact in a large systemic lupus erythematosus (SLE) retrospective cohort. METHODS: All patients in the Spanish Rheumatology Society Lupus Registry (RELESSER) who meet ?4 ACR-97 SLE criteria were retrospectively investigated for severe infections. Patients with and without infections were compared in terms of SLE severity, damage, comorbidities, and demographic characteristics. A multivariable Cox regression model was built to calculate hazard ratios (HRs) for the first infection. RESULTS: A total of 3658 SLE patients were included: 90% female, median age 32.9 years (DQ 9.7), and mean follow-up (months) 120.2 (±87.6). A total of 705 (19.3%) patients suffered ?1 severe infection. Total severe infections recorded in these patients numbered 1227. The incidence rate was 29.2 (95% CI: 27.6-30.9) infections per 1000 patient years. Time from first infection to second infection was significantly shorter than time from diagnosis to first infection (p < 0.000). Although respiratory infections were the most common (35.5%), bloodstream infections were the most frequent cause of mortality by infection (42.0%). In the Cox regression analysis, the following were all associated with infection: age at diagnosis (HR = 1.016, 95% CI: 1.009-1.023), Latin-American (Amerindian-Mestizo) ethnicity (HR = 2.151, 95% CI: 1.539-3.005), corticosteroids (?10mg/day) (HR = 1.271, 95% CI: 1.034-1.561), immunosuppressors (HR = 1.348, 95% CI: 1.079-1.684), hospitalization by SLE (HR = 2.567, 95% CI: 1.905-3.459), Katz severity index (HR = 1.160, 95% CI: 1.105-1.217), SLICC/ACR damage index (HR = 1.069, 95% CI: 1.031-1.108), and smoking (HR = 1.332, 95% CI: 1.121-1.583). Duration of antimalarial use (months) proved protective (HR = 0.998, 95% CI: 0.997-0.999). CONCLUSIONS: Severe infection constitutes a predictor of poor prognosis in SLE patients, is more common in Latin-Americans and is associated with age, previous infection, and smoking. Antimalarials exerted a protective effect. Spanish Foundation of Rheumatology. FIS/ISCIII (grant number PI11/02857).

A biomarker is a biological parameter that can be measured in blood or other body fluids or tissues and used as a sign of a normal or abnormal process, or of a condition or disease. In medicine, a biomarker can be used to diagnose a disease, to establish its prognosis or as a surrogate marker of outcome in research. In recent years, there has been strong interest in discovering new biomarkers, as well as in the development of new uses for well-known biomarkers in distinct diseases. In this article, the utility of several biomarkers not routinely used in rheumatology (procalcitonin, natriuretic peptides and cardiac troponins) in the diagnosis and follow-up of patients with systemic autoimmune diseases is reviewed.

Objective. To critically appraise the validity of activity indices used in the followup of patients with undifferentiated peripheral inflammatory arthritis (UPIA). Methods. A systematic review was performed in Medline, Embase, the Cochrane Library, and abstracts presented at the 2007 and 2008 meetings of the American College of Rheumatology and European League Against Rheumatism. Selection criteria were: patients with UPIA, the assessment of instruments to evaluate disease activity, and assessment of validity of the instruments. Two reviewers screened titles and abstracts independently and collected data using ad hoc standard forms. Results. The search yielded 179 articles and 834 abstracts, of which 4 articles and 1 abstract were included. We found no study that validated Disease Activity Score (DAS), Clinical Disease Activity Index (CDAI), or Simplified Disease Activity Index (SDAI). Included studies addressed validation of 4 questionnaires: WHO Disability Assessment Schedule (WHODAS), London Handicap Scale (LHS), Disease Repercussion Profile (DRP), and the Health Assessment Questionnaire (HAQ); and 3 indexes: RA Disease Activity Index (RADAI), McGill Range of Motion Index (McROMI), and NOAR Damaged Joint Count (NOAR-DJC). Questionnaires were self-administered and feasible; RADAI was the most feasible index. Internal consistency was studied in the questionnaires (Cronbach’s α > 0.83). Responsiveness was tested in the DRP, LHS, and HAQ, but the approach to study sensitivity to change was poorly explained, with no clear intervention. Construct validity, examined by means of convergence with other instruments, was generally moderate, and slightly higher for the RADAI. Conclusion. No instrument of disease activity has been fully validated for use in UPIA. We found no direct evidence of what is the most useful index to follow up patients with UPIA.

Some occupational factors have been implicated in the development of disorders manifested as hand pain. The associations seem to be well documented in processes such as hand-arm vibration syndrome (HAVS) or writer's cramp. There are contradictory data in the literature about the relationships of trigger finger, De Quervain's tenosynovitis (DQT) and tenosynovitis of the wrist with occupational factors. In this article, we review current knowledge about clinical manifestations, case definition, implicated occupational factors, diagnosis and treatment of the most relevant hand pain disorders that have been associated with occupational factors, excluding carpal tunnel syndrome (CTS).

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease. Autoantibody production plays a critical role in its pathogenic pathways. Thus, B-cell directed biologic therapy is a logical option. The present article reviews the latest advances in the development of B-cell directed biological agents in the treatment of SLE. Rituximab has been studied in a number of open series of patients that suggest efficacy but two recent controlled clinical trials have failed to show efficacy versus placebo. In contrast, a recent placebo-controlled, double-blind, randomized trial has reported that belimumab has statistically significant efficacy versus placebo. Atacicept, a fusion protein that blocks cytokines that play a critical role in the differentiation and survival of B-cells and plasma cells, markedly reduces autoantibody levels but could increase the risk of infection. Further studies are needed to establish the role of B-cell directed biologic therapy in SLE.

What is the best rheumatoid arthritis therapy after failure of a first anti-TNF drug? No consensus has been reached on whether to switch to rituximab or an alternative TNF inhibitor. New observational studies suggest that either course can be effective. But are more data needed?

Shoulder pain is one of the most common presenting complaints in daily clinical practice. The assessment of patients with shoulder pain is usually complicated due to the wide variety of possible etiologies. Physical examination of the shoulder is especially important in the assessment of soft tissue disorders, since there are a number of physical examination manoeuvres specifically designed to examine particular structures. In this article, the various clinical tests and their diagnostic utility for examining subacromial impingement, supraspinatus, infraspinatus, subscapularis and biceps tendons, gleno-humeral instability and the acromioclavicular joint are reviewed and compared with procedures considered as the gold standard.

La nefritis lupica es una causa importante de morbilidad y mortalidad en los pacientes con lupus eritematoso sistemico. El tratamiento convencional de induccion de remision en la nefritis lupica grave se basa en la utilizacion de ciclofosfamida intravenosa mensual. Datos recientes han puesto de manifiesto que se consigue mantener la remision de la nefritis lupica con azatioprina o micofenolato, con un menor numero de efectos secundarios que con la administracion trimestral de ciclofosfamida intravenosa. En los ultimos anos se han publicado ensayos clinicos controlados y aleatorizados que plantean nuevas modalidades terapeuticas en la induccion de remision en nefritis lupica, como la utilizacion de pautas menos agresivas de ciclofosfamida intravenosa o el uso de micofenolato mofetilo. Son necesarios mas estudios para establecer el tratamiento optimo de los pacientes con nefritis lupica grave.

Lupus nephritis is a relevant source of morbidity and mortality in patients with systemic lupus erythematosus. The standard therapy of remission induction in severe lupus nephritis is based on the use of monthly intravenous cyclophosphamide. Recent data have established that the maintenance of remission in lupus nephritis can be achieved with azathioprine or mycophenolate mofetil, with less adverse effects than quarterly intravenous cyclophosphamide. In recent years, a number of controlled randomized clinical trials have been published, opening new therapeutic options in the induction of remission in lupus nephritis, such as less aggressive regimens of intravenous cyclophosphamide or mycophenolate mofetil. Further studies are needed for establishing the optimal therapy of lupus nephritis patients.

provide solid evidence that low-dose GC can inhibit radiographic damage in early RA, and that side effects of GC, when used in that clinical framework, are limited to hyperglycaemia, cataracts, and transient weight gain.

Interstitial lung disease (ILD) occurs frequently in patients with systemic sclerosis (SSc), with a burden of significant morbidity and mortality. SSc-ILD resembles idiopathic pulmonary fibrosis (IPF) in many respects, including a restrictive ventilatory defect that results from an active fibrosing process in the lung interstitium, a ground glass opacification on high resolution computed tomography, and inflammatory cells in bronchoalveolar lavage fluid. Differences in the classification of lung histo-pathology are noted frequently and may account for some of the differences in outcome for patients with SSc-ILD and IPF. Optimal treatment of SSc-ILD remains to be determined, but cyclophosphamide has been reported to be effective in several open observational studies. Results from the Scleroderma Lung Study are expected to add new insights into the optimal therapy for SSc-ILD.

Rheumatoid arthritis (RA) is a severe disease that leads to joint destruction, loss of function and premature death. To achieve the induction of remission is a major therapeutic goal. The use of conventional disease-modifying anti-rheumatic drugs (DMARDs) as monotherapy rarely allows to achieve and maintain an adecuate clinical response over the course of the disease. This article reviews the role of the combination therapy with conventional DMARDs in the early-onset and refractory rheumatoid disease. In addition, the role that should play these combination therapies in the current therapeutic armamentarium of RA after the advent of the new biologic agents is critically discussed.

Current treatment options for systemic lupus erythematosus (SLE) fail to control all the manifestations of the disease or fully prevent flares. The most extensively studied biological therapies are directed against B cells, although other biological targets have also been explored. Biological agents against tumor necrosis factor-alfa differ in their efficacy and have been associated with the generation of antinuclear and anti-dsDNA antibodies. Anti-interleukin-10 and anti-interleukin-6 agents have also been studied, with encouraging results. Abatacept, which has been approved in rheumatoid arthritis, has not shown efficacy in placebo-controlled clinical trials.

El tratamiento con agentes contra el factor de necrosis tumoral (TNF) alfa se ha asociado a la reactivacion de la infeccion cronica por el virus de la hepatitis B. Algunos casos publicados indican la necesidad de tratamiento cronico con lamivudina cuando se utilizan los agentes anti-TNFa. Describimos el caso de un paciente con espondilitis anquilosante y antigeno de superficie positivo tratado con infliximab y lamivudina. La respuesta clinica fue excelente, pero cuando el paciente interrumpio el tratamiento con lamivudina, se observo reactivacion de la replicacion viral. Una vez reinstaurado dicho tratamiento, se controlo nuevamente la replicacion viral y se normalizaron las concentraciones de transaminasas. Esta observacion indica que en pacientes con infeccion cronica por VHB que necesitan tratamiento anti-TNFa, se requiere un tratamiento preventivo a largo plazo con lamivudina.

Anti-tumor necrosis factor-a (TNF) therapy has been associated with reactivation of hepatitis B virus infection. Case reports have suggested the concomitant need of lamivudine treatment in patients with HBV infection treated with antiTNFa agents. We describe a case of ankylosing spondylitis with positive HBV surface antigen (HBsAg) treated with infliximab and lamivudine. Clinical response was excellent but when lamivudine therapy was stopped, reactivation of replication viral occurred. After the reintroduction of lamivudine, viral replication was controlled and liver function tests were normalized. Preventive long-term lamivudine therapy is mandatory when anti-TNFa therapy is maintained in patients with chronic HBV infection.

Objective. To evaluate the diagnostic and prognostic utility of genetic testing in undifferentiated peripheral inflammatory arthritis (UPIA). Methods. A systematic literature search was performed in Medline, Embase, the Cochrane Library, and abstracts presented at the 2007 and 2008 meetings of the American College of Rheumatology and the European League Against Rheumatism. The target studies were those evaluating diagnostic or prognostic value of genetic markers specifically in UPIA. Two reviewers independently screened titles and abstracts and reviewed included articles in detail. All data were collected using ad hoc standard forms, permitting the calculation of positive and negative likelihood ratios of each genetic marker for diagnoses of different rheumatic diseases and for the development of relevant outcomes. Results. Of the 3109 articles retrieved, 26 original studies fulfilled criteria of the systematic review. The most frequent diagnosis tested was rheumatoid arthritis, followed by inflammatory polyarthritis, and spondyloarthropathies. The main prognostic outcome evaluated was development of erosions, followed by median Larsen score, remission, Health Assessment Questionnaire (HAQ) score, and persistent synovitis. In total, 122 genetic markers were tested. No genetic marker had a high likelihood ratio for the diagnosis of a specific rheumatic disease. The shared epitope was associated with poor prognosis (erosions, HAQ > 1, mortality, and persistent synovitis). Other genes did not predict outcome in undifferentiated arthritis. Other outcomes for persistent disease or disability were not studied in depth. Conclusion. In isolation, no studied genetic marker is very informative of a future diagnosis in patients with UPIA. The shared epitope has a slight association with poor prognosis of UPIA.

Glucocorticoids (GC) are a mainstay of the therapy in rheumatoid arthritis (RA). Currently, and despite their extensive use, the discussion about the benefits and adverse effects of low dose GC in the management of RA persists. In recent years, a number of clinical trials have attempted to establish the benefits of long-term GC use as a disease-modifying antirheumatic drug in RA, and to define their side effects. Results of these clinical trials provide solid evidence that low-dose GC can inhibit radiographic damage in early RA, and that side effects of GC, when used in that clinical framework, are limited to hyperglycaemia, cataracts, and transient weight gain.
