Vitamin D plays a major role in bone health and probably also in multiple extraskeletal acute and chronic diseases. Although supplementation with calcifediol, a vitamin D metabolite, has demonstrated efficacy and safety in short-term clinical trials, its effects after long-term monthly administration have been studied less extensively. This report describes the results of a 1-year, phase III-IV, double-blind, randomized, controlled, parallel, multicenter superiority clinical trial to assess the efficacy and safety of monthly calcifediol 0.266 mg versus cholecalciferol 25,000 IU (0.625 mg) in postmenopausal women with vitamin D deficiency (25(OH)D

Vitamin D has shown to play a role in multiple diseases due to its skeletal and extraskeletal actions. Furthermore, vitamin D deficiency has become a worldwide health issue. Few supplementation guidelines mention calcifediol treatment, despite being the direct precursor of calcitriol and the biomarker of vitamin D status. This 1-year, phase III-IV, double-blind, randomized, controlled, multicenter clinical trial assessed the efficacy and safety of calcifediol 0.266 mg soft capsules in vitamin D-deficient postmenopausal women, compared to cholecalciferol. Results reported here are from a prespecified interim analysis, for the evaluation of the study's primary endpoint: the percentage of patients with serum 25-hydroxyvitamin D (25(OH)D) levels above 30 ng/ml after 4 months. A total of 303 patients were enrolled, of whom 298 were included in the intention-to-treat (ITT) population. Patients with baseline levels of serum 25(OH)D

Mutations in SQSTM1 are strongly associated with Paget's disease of bone (PDB), but little is known about the clinical characteristics of those with early disease. Radionuclide bone scans, biochemical markers of bone turnover, and clinical characteristics were analyzed in SQSTM1 mutation carriers who took part in the Zoledronic acid in the Prevention of Paget's disease (ZiPP) study. We studied 222 individuals, of whom 54.9% were female, with mean ± SE age of 50.1 ± 0.6 years. Twelve SQSTM1 mutations were observed, including p.Pro392Leu, which was present in 141 of 222 (63.5%) subjects. Bone scan examination revealed evidence of PDB in 20 subjects (9.0%), ten of whom (50%) had a single affected site. Participants with lesions were older than those without lesions but the difference was not significant (53.6 ± 9.1 versus 49.8 ± 8.9; p = .07). The mean age of participants with lesions was not significantly different from the age at which their parents were diagnosed with PDB (55 years versus 59 years, p = .17). All individuals with lesions were asymptomatic. Serum concentrations of total alkaline phosphatase (ALP) normalized to the upper limit of normal in each center were higher in those with lesions (0.75 ± 0.69 versus 0.42 ± 0.29 arbitary units; p

To describe the clinical and therapeutic management of rheumatoid arthritis (RA) patients with biological disease-modifying antirheumatic drugs (bDMARDs), alone or in combination with conventional synthetic DMARDs (csDMARDs), as well as analysing changes over time in bDMARD use. An observational, retrospective, multicentre study was conducted in the rheumatology departments of 10 public Spanish hospitals. Patients with RA treated with bDMARDs at baseline who had medical records available in the data collection period 2013-2016 were included. All visits to rheumatology departments recording any type of bDMARD modification (dose, etc.) were collected. Clinical characteristics, concomitant treatment, resource use, work productivity and quality of life (QoL) were recorded. 128 patients were included: 81 received first-line bDMARD treatment, 28 second-line bDMARD treatment and 19 received third or later lines. Mean study follow-up was 4.1 years. Assessment of DAS28 was available in 54.6% of visits. At baseline, 48.7% of patients had moderate-high disease activity. At final observation, 69.5% of patients continued with the first bDMARD. Tumour necrosis factor blockers were administered to 85.2% of patients in first line, 45.7% in second line and 18.1% in third or later lines. At final observation, 80.2% of patients still felt pain/discomfort. As expected, those with higher disease activity had higher loss of work productivity and lower QoL, as assessed by DAS28, than patients with lower disease activity. Drugs represented 82.6% of the total cost. In this Spanish cohort of 128 patients, most patients remained on the first prescribed bDMARD, despite remaining signs and symptoms.

The different sets of criteria for diagnosis or classification of anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) lead to numerous overlapping and reclassified diagnoses in clinical practice. We designed this study to assess the difficulties in classifying patients with AAV. As a secondary objective, different variables were tested to predict prognosis. We conducted a retrospective chart review in a Western Spain multicentre survey. A total of 115 adult patients diagnosed with AAV from 2002 to 2013 and followed for at least 3 years were included. They were classified according to (1) Chapel Hill Consensus Conference (CHCC), (2) European Medicines Agency algorithm and (3) French Vasculitis Study Group/European Vasculitis Society phenotypes. Fifty-three patients (46%) had neither distinctive histopathological data of a single AAV definition nor any surrogate markers for granulomatous inflammation and thus did not fulfill any diagnostic criteria. Ocular, ear, nose, throat, skin, and lung involvement were more frequent with proteinase 3 (PR3) antibodies, whereas peripheral neuropathy was more frequent with myeloperoxidase (MPO) antibodies. When the disease was severe at diagnosis, the HR for mortality was 10.44. When induction treatment was not given in accordance with the guidelines, the HR for mortality was 4.00. For maintenance treatment, the HR was 5.49 for mortality and 2.48 for relapse. AAV classification is difficult because many patients had neither specific clinical data nor distinctive histological features of a single CHCC definition. A structured clinical assessment of patient severity is the best tool to guide the management of AAV.

Objective Describe the objectives, methods and results of the first year of the new version of the Spanish registry of adverse events involving biological therapies and synthetic drugs with an identifiable target in rheumatic diseases (BIOBADASER III). Methodology Multicenter prospective registry of patients with rheumatic inflammatory diseases being treated with biological drugs or synthetic drugs with an identifiable target in rheumatology departments in Spain. The main objective of BIOBADASER phase III is the registry and analysis of adverse events; moreover, a secondary objective was added consisting of assessing the effectiveness by means of the registry of activity indexes. Patients in the registry are evaluated at least once every year and whenever they experience an adverse event or a change in treatment. The collection of data for phase III began on 17 December 2015. Results During the first year, 35 centres participated. The number of patients included in this new phase in December 2016 was 2664. The mean age was 53.7 years and the median duration of treatment was 8.1 years. In all, 40.4% of the patients were diagnosed with rheumatoid arthritis. The most frequent adverse events were infections and infestations. Conclusions BIOBADASER phase III has been launched to adapt to a changing pharmacological environment, with the introduction of biosimilars and small molecules in the treatment of rheumatic diseases. This new stage is adapted to the changes in the reporting of adverse events and now includes information related to activity scores.

Paget¿s disease of bone (PDB) is characterized by increased bone resorption followed by an excessive compensatory bone formation, with an abnormal bone structure with altered mechanical properties. Pagetic bone also has a higher vascularization and marrow fibrosis. Despite of pagetic bone being a highly vascularized tissue, there are no studies on the plasma levels of angiogenic mediators in the different states of the disease; moreover, the effect of PDB treatment on plasma levels of these angiogenic mediators is not very well known. The aim of this study was to analyse plasma levels of cytokines implicated in the increased bone turnover (OPG, RANKL, sclerostin) and hypervascularization (VEGF, PGF, ENG) observed in PDB and their evolution and response to zoledronic acid treatment in 70 PDB patients, 29 with an active disease measured by plasma alkaline phosphatase (ALP). Plasma ALP concentration was higher in active PDB than in inactive PDB patients, whereas there were no differences in OPG, RANKL, sclerostin, VEGF, PGF and ENG plasma levels between active and inactive PDB patients. ALP decreased at 3 and 12 months after zoledronic acid treatment. RANKL levels were reduced and sclerostin levels were increased after 12 months of treatment. PGF levels were lower 12 months after zoledronic acid treatment, whereas there were no differences in plasma VEGF and ENG after zoledronic acid treatment. Summarizing, zoledronic acid treatment is associated to decreases in plasma levels of ALP, RANKL, sclerostin and P1GF in active PDB patients. This treatment may reduce bone turnover and might reduce the pathological vascularisation typical of pagetic bone., This work was supported by grants from Instituto de Salud Carlos III (Ministry of Economy and Competitiveness, PI12/00959, PI13/01741, PI15/01055, Kidney Research Network REDINREN RD012/0021/0032 and RD016/0009/0025, co-funded by FEDER) and Junta de Castilla y León (Ministry of Health, GRS 969/A/14).

Schizophrenia is a clinically heterogeneous syndrome affecting multiple dimensions of patients’ life. Therefore, its treatment might require a multidimensional approach that should take into account the efficacy (the ability of an intervention to get the desired result under ideal conditions), the effectiveness (the degree to which the intended effect is obtained under routine clinical practice conditions or settings) and the efficiency (value of the intervention as relative to its cost to the individual or society) of any therapeutic intervention. In a first step of the process, a group of 90 national experts from different areas of health-care and with a multidimensional and multidisciplinary perspective of the disease, defined the concepts of efficacy, effectiveness and efficiency of established therapeutic interventions within 7 key dimensions of the illness: symptomatology; comorbidity; relapse and adherence; insight and subjective experience; cognition; quality of life, autonomy and functional capacity; and social inclusion and associated factors. The main conclusions and recommendations of this stage of the work are presented herein.

Introduction Paget’s disease of bone (PDB) is characterised by increased and disorganised bone remodelling affecting one or more skeletal sites. Complications include bone pain, deformity, deafness and pathological fractures. Mutations in sequestosome-1 (SQSTM1) are strongly associated with the development of PDB. Bisphosphonate therapy can improve bone pain in PDB, but there is no evidence that treatment alters the natural history of PDB or prevents complications. The Zoledronate in the Prevention of Paget’s disease trial (ZiPP) will determine if prophylactic therapy with the bisphosphonate zoledronic acid (ZA) can delay or prevent the development of PDB in people who carry SQSTM1 mutations. Methods and analysis People with a family history of PDB aged >30 years who test positive for SQSTM1 mutations are eligible to take part. At the baseline visit, participants will be screened for the presence of bone lesions by radionuclide bone scan. Biochemical markers of bone turnover will be measured and questionnaires completed to assess pain, health-related quality of life (HRQoL), anxiety and depression. Participants will be randomised to receive a single intravenous infusion of 5 mg ZA or placebo and followed up annually for between 4 and 8 years at which point baseline assessments will be repeated. The primary endpoint will be new bone lesions assessed by radionuclide bone scan. Secondary endpoints will include changes in biochemical markers of bone turnover, pain, HRQoL, anxiety, depression and PDB-related skeletal events. Ethics and dissemination The study was approved by the Fife and Forth Valley Research Ethics Committee on 22 December 2008 (08/S0501/84). Following completion of the trial, a manuscript will be submitted to a peer-reviewed journal. The results of this trial will inform clinical practice by determining if early intervention with ZA in presymptomatic individuals with SQSTM1 mutations can prevent or slow the development of bone lesions with an adverse event profile that is acceptable. Trial registration number ISRCTN11616770

Paget's disease of bone (PDB) is a bone disorder characterized by an increase in bone turnover in a disorganized way with a large increase in bone resorption followed by bone formation. The most important known genetic factor predisposing to PDB is mutation in Sequestosome1 (SQSTM1) gene. We have studied the prevalence of SQSTM1 mutations and examined genotype-phenotype correlations in a Spanish cohort of PDB patients. Also, we have characterized three PDB patients that carry the c.961C>T SQSTM1 gene mutation that it is localized in exon 6 of SQSTM1 gene and it causes the p. R321C mutation. This mutation has been reported in patients with amyotrophic lateral sclerosis and frontotemporal dementia but in our knowledge this is the first time that p62 p. R321C mutation is associated to PDB. We show that p62 p.R321C mutation could induce blockage of autophagy and cell proliferation through NF-kB pathway. These results reinforce the hypothesis of autophagy involvement in Paget's disease of bone., This work was supported by grants from Instituto de Salud Carlos III (Ministry of Economy and Competitiveness) (ISC IIII-FEDER: PI10/00219 and PI13/01741).

To formulate SER recommendations for the use of biological agents in primary Sjögren's syndrome (pSS).Relevant clinical research questions were identified on the use of biological agents in pSS. The clinical questions were reformulated into 4PICO questions. A search strategy was designed and a review of the scientific evidence of studies published until May 2017 was carried out. The scientific evidence available was systematically reviewed. The overall level of scientific evidence was assessed using the SIGN evidence levels. After that, specific recommendations were made.Rituximab is recommended as the biological agent of choice for extraglandular manifestations refractory to conventional treatment. The use of anti-TNF agents is discouraged. The scientific evidence with belimumab and abatacept is scarce, so they should be considered only in cases refractory to rituximab.Rituximab is the biological agent of choice in severe extraglandular manifestations of pSS. Belimumab or abatacept may be useful in selected cases.

[Objectives]: To identify genetic determinants of susceptibility to clinical vertebral fractures, which is an important complication of osteoporosis., [Methods]: Here we conduct a genome-wide association study in 1553 postmenopausal women with clinical vertebral fractures and 4340 controls, with a two-stage replication involving 1028 cases and 3762 controls. Potentially causal variants were identified using expression quantitative trait loci (eQTL) data from transiliac bone biopsies and bioinformatic studies., [Results]: A locus tagged by rs10190845 was identified on chromosome 2q13, which was significantly associated with clinical vertebral fracture (P=1.04×10−9) with a large effect size (OR 1.74, 95% CI 1.06 to 2.6). Bioinformatic analysis of this locus identified several potentially functional SNPs that are associated with expression of the positional candidate genes TTL (tubulin tyrosine ligase) and SLC20A1 (solute carrier family 20 member 1). Three other suggestive loci were identified on chromosomes 1p31, 11q12 and 15q11. All these loci were novel and had not previously been associated with bone mineral density or clinical fractures., [Conclusion]: We have identified a novel genetic variant that is associated with clinical vertebral fractures by mechanisms that are independent of BMD. Further studies are now in progress to validate this association and evaluate the underlying mechanism., ORCADES was supported by the Chief Scientist Office of the Scottish Government (CZB/4/276, CZB/4/710), the Royal Society, the MRC Human Genetics Unit, Arthritis Research UK and the European Union framework programme 6 EUROSPAN project (contract no.

BACKGROUND: Bisphosphonates are considered to be the treatment of choice for people with Paget's disease of bone. However, the effects of bisphosphonates on patient‐centred outcomes have not been extensively studied. There are insufficient data to determine whether reducing and maintaining biochemical markers of bone turnover to within the normal range improves quality of life and reduces the risk of complications. OBJECTIVES: To assess the benefits and harms of bisphosphonates for adult patients with Paget's disease of bone. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, ISI Web of Knowledge and trials registers up to March 2017. We searched regulatory agency published information for rare adverse events. SELECTION CRITERIA: Randomised controlled trials (RCTs) of bisphosphonates as treatment for Paget's disease in adults. DATA COLLECTION AND ANALYSIS: Two review authors independently screened search results, extracted data and assessed studies for risk of bias. We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: We included 20 trials (25 reports, 3168 participants). Of these, 10 trials (801 participants) compared bisphosphonates (etidronate, tiludronate, ibandronate, pamidronate, olpadronate, alendronate, risedronate, zoledronate) versus placebo, seven compared two bisphosphonates (992 participants), one trial compared a bisphosphonates with a bisphosphonate plus calcitonin (44 participants), and two studies, the largest trial (1331 participants) and its interventional extension study (502 participants), compared symptomatic treatment and intensive treatment where the goal was to normalise alkaline phosphatase. Most studies were assessed at low or unclear risk of bias. Six of 10 studies comparing bisphosphonates versus placebo were assessed at high risk of bias, mainly around incomplete outcome data and selective outcome reporting. Participant populations were reasonably homogeneous in terms of age (mean age 66 to 74 years) and sex (51% to 74% male). Most studies included participants who had elevated alkaline phosphatase levels whether or not bone pain was present. Mean follow‐up was six months. Bisphosphonates versus placebo Bisphosphonates tripled the proportion (31% versus 9%) of participants whose bone pain disappeared (RR 3.42, 95% confidence interval (CI) 1.31 to 8.90; 2 studies, 205 participants; NNT 5, 95% CI 1 to 31; moderate‐quality evidence). This result is clinically important. Data were consistent when pain change was measured as any reduction (RR 1.97, 95% CI 1.29 to 3.01; 7 studies, 481 participants). There was uncertainty about differences in incident fractures: 1.4% fractures occurred in the bisphosphonates group and none in the placebo group (RR 0.89, 95% CI 0.18 to 4.31; 4 studies, 356 participants; very low‐quality evidence). None of the studies reported data on orthopaedic surgery, quality of life or hearing thresholds. Results regarding adverse effects and treatment discontinuation were uncertain. There was a 64% risk of mild gastrointestinal adverse events in intervention group participants and 48% in the control group (RR 1.32, 95% CI 0.91 to 1.92; 6 studies, 376 participants; low‐quality evidence). The likelihood of study participants discontinuing due to adverse effects was slightly higher in intervention group participants (4.4%) than the control group (4.1%) (RR 1.01, 95% CI 0.41 to 2.52; 6 studies, 517 participants; low‐quality evidence). Zoledronate was associated with an increased risk of transient fever or fatigue (RR 2.57, 95% CI 1.21 to 5.44; 1 study, 176 participants; moderate‐quality evidence). Bisphosphonates versus active comparator More participants reported pain relief with zoledronate than pamidronate (RR 1.30, 95% CI 1.10 to 1.53; 1 study, 89 participants; NNT 5, 95% CI 3 to 11) or risedronate (RR 1.36, 95% CI 1.06 to 1.74; 1 study, 347 participants; NNT 7, 95% CI 4 to 24; very low quality evidence). This result is clinically important. There was insufficient evidence to confirm or exclude differences in adverse effects of bisphosphonates (RR 1.05, 95% CI 0.95 to 1.76; 2 studies, 437 participants; low‐quality evidence) and treatment discontinuation (2 studies, 437 participants) (RR 2.04, 95% CI 0.43 to 9.59; 2 studies, 437 participants; very low‐quality evidence). Intensive versus symptomatic treatment There was no consistent evidence of difference to response in bone pain, bodily pain or quality of life in participants who received intensive versus symptomatic treatment. Inconclusive results were observed regarding fractures and orthopaedic procedures for intensive versus symptomatic treatment (intensive treatment for fracture: RR 1.84, 95% CI 0.76 to 4.44; absolute risk 8.1% versus 5.2%; orthopaedic procedures: RR 1.58, 95% CI 0.80 to 3.11; absolute risk 5.6% versus 3.0%; 1 study, 502 participants; low‐quality evidence). There was insufficient evidence to confirm or exclude an important difference in adverse effects between intensive and symptomatic treatment (RR 1.05, 95% CI 0.79 to 1.41; low‐quality evidence). There was insufficient evidence to confirm or exclude an important difference of risk of rare adverse events (including osteonecrosis of the jaw) from the regulatory agencies databases. AUTHORS' CONCLUSIONS: We found moderate‐quality evidence that bisphosphonates improved pain in people with Paget's disease of bone when compared with placebo. We are uncertain about the results of head‐to‐head studies investigating bisphosphonates. We found insufficient evidence of benefit in terms of pain or quality of life from intensive treatment. Information about adverse effects was limited, but serious side effects were rare, and rate of withdrawals due to side effects was low.

SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome is a cluster of osteo-cutaneous manifestations that can lead to serious complications such as thrombosis of the subclavian vein or superior vena cava, mainly in patients with significant inflammatory involvement of the anterior chest wall. The objective of this study was to review the cases published in the medical literature related with the presence of thrombotic complications in patients diagnosed with SAPHO syndrome and to try to determine their possible pathogenic mechanism and risk factors. We analyzed 11 published reports of isolated clinical cases or case series, a total of 144 patients, which described a total of 15 cases of venous thrombosis. The clinical characteristics of these patients, evaluated to determine whether they meet the ASAS criteria for axial and peripheral spondyloarthritis, are analyzed and the need for early diagnosis and treatment is highlighted.

Resumen El sindrome SAPHO (sinovitis, acne, pustulosis, hiperostosis y osteitis) comprende un conjunto de manifestaciones cutaneo-osteoarticulares. Se han descrito algunas complicaciones graves que pueden aparecer durante la evolucion de la enfermedad, como la trombosis venosa, principalmente en pacientes que desarrollan afectacion inflamatoria grave de la pared toracica anterior. El objetivo de la presente revision fue analizar los casos descritos en la literatura medica relacionados con la presencia de complicaciones tromboticas en pacientes diagnosticados de sindrome SAPHO e intentar establecer los probables factores de riesgo y su posible mecanismo patogenico. Se analizaron 11 articulos publicados de casos clinicos aislados o series de casos, con un total de 144 pacientes, que describen en total 15 casos de trombosis venosa. Se exponen las caracteristicas clinicas de estos pacientes, se evalua si cumplen los criterios de clasificacion ASAS para espondiloatritis axial y periferica, y se resalta la necesidad de realizar un diagnostico y tratamiento precoces.

Describe the objectives, methods and results of the first year of the new version of the Spanish registry of adverse events involving biological therapies and synthetic drugs with an identifiable target in rheumatic diseases (BIOBADASER III).Multicenter prospective registry of patients with rheumatic inflammatory diseases being treated with biological drugs or synthetic drugs with an identifiable target in rheumatology departments in Spain. The main objective of BIOBADASER Phase III is the registry and analysis of adverse events; moreover, a secondary objective was added consisting of assessing the effectiveness by means of the registry of activity indexes. Patients in the registry are evaluated at least once every year and whenever they experience an adverse event or a change in treatment. The collection of data for phase iii began on 17 December 2015.During the first year, 35 centers participated. The number of patients included in this new phase in December 2016 was 2,664. The mean age was 53.7 years and the median duration of treatment was 8.1 years. In all, 40.4% of the patients were diagnosed with rheumatoid arthritis. The most frequent adverse events were infections and infestations.BIOBADASER Phase III has been launched to adapt to a changing pharmacological environment, with the introduction of biosimilars and small molecules in the treatment of rheumatic diseases. This new stage is adapted to the changes in the reporting of adverse events and now includes information related to activity scores.

Hyperprolactinemia is an underappreciated/unknown adverse effects of antipsychotics. The consequences of hyperprolactinemia compromise therapeutic adherence and can be serious. We present the consensus recommendations made by a group of experts regarding the management of antipsychotic-induced hyperprolactinemia. The current consensus was developed in 3 phases: 1, review of the scientific literature; 2, subsequent round table discussion to attempt to reach a consensus among the experts; and 3, review by all of the authors of the final conclusions until reaching a complete consensus. We include recommendations on the appropriate time to act after hyperprolactinemia detection and discuss the evidence on available options: decreasing the dose of the antipsychotic drug, switching antipsychotics, adding aripiprazole, adding dopaminergic agonists, and other type of treatment. The consensus also included recommendations for some specific populations such as patients with a first psychotic episode and the pediatric-youth population, bipolar disorder, personality disorders and the elderly population.

La Enfermedad Ósea de Paget (EOP) es la enfermedad metabólica ósea más frecuente después de la osteoporosis. Aunque suele cursar de manera asintomática, es importante pensar en ella en pacientes que consultan por dolor óseo, deformidad ósea, o en pacientes con elevación de Fosfatasa Alcalina sin hepatopatía. Presentamos el caso de una pacientes con EOP afectando al radio, una localización extremadamente infrecuente de esta enfermedad.

Paget's disease of bone (PDB) has a strong genetic component. Here, we investigated possible associations between genetic variants that predispose to PDB and disease severity. Allelic variants identified as predictors of PDB from genome-wide association studies were analyzed in 1940 PDB patients from the United Kingdom, Italy, Western Australia, and Spain. A cumulative risk allele score was constructed by adding the variants together and relating this to markers of disease severity, alone and in combination with SQSTM1 mutations. In SQSTM1-negative patients, risk allele scores in the highest tertile were associated with a 27% increase in disease extent compared with the lowest tertile (p

Context Several studies have suggested that the prevalence and severity of PDB have fallen in recent years. The magnitude of this trend and its globalization have not been well established. Objective The objective of this study is to estimate the pooled magnitude of the changes in the prevalence of PDB and as a secondary objective, to make up a world atlas of PDB prevalence. Methods A systematic review of English and non-English articles using MEDLINE (1946 to 2013) and EMBASE (1980 to 2013) was the method used. Search terms included epidemiology, incidence, prevalence, cohort studies, osteitis deformans or Paget's disease of bone. Studies with incidence and/or prevalence rate for PDB were included. Two authors independently extracted the data using predefined data fields and quality assessment. A pooled analysis based on random-effects models was carried out for secular trends. Results Twenty-eight articles documented the prevalence of PDB; four articles the incidence and two articles the rate of new referrals. The prevalence of PDB varied greatly between the different countries, from 0.00028% in Japan to 5.4% in the UK. There were available data on changes in prevalence from two different surveys over two different time frames in Europe and New Zealand. In all but one city (Turin), a drop in the prevalence of PDB was recorded (pooled OR 0.64; 95% CI 0.45–0.91). Conclusion The incidence and prevalence rates of PDB vary widely between populations but both have decreased in most regions over recent years. The changes are heterogeneous however and within countries, the largest changes have been in areas that previously had a high prevalence. The reasons for these changes remain unclear at present but are likely to be due to an interaction between genetic factors and environmental triggers which may differ in different regions.

Background: Cases of renal tubular dysfunction have been reported in patients with hepatitis B and in patients with human immunodeficiency virus who are undergoing tenofovir treatment. However, little is known about the impact on tubular function in patients with chronic hepatitis B (CHB) under long-term use of entecavir (ETV) and tenofovir disoproxil fumarate (TDF). We evaluated markers of renal tubular function and bone turnover in patients with CHB treated with ETV or TDF. Patients and Methods: A multicenter, cross-sectional study was performed on markers of renal tubular function and bone turnover in hepatitis B virus-monoinfected patients on long-term treatment with Entecavir or Tenofovir (the MENTE study). The analyzed parameters were: retinol-binding protein/creatinine, neutrophil gelatinase-associated lipocalin/creatinine, excretion of phosphates, uric acid excretion, glomerular filtrate, protein/creatinine, albumin/ creatinine, serum creatinine, phosphate, CTX, P1NP, vitamin D, and parathormone. Results: A total of 280 patients (ETV: 89, TDF: 69, control: 122) were included in this study. The TDF group was associated with altered levels of retinol-binding protein (RBP)/creatinine (TDF 25% vs. 7% ETV and control; P < 0.001). Protein/creatinine, uric acid excretion, P1NP1, and parathormone were higher in the TDF group. The proportion of patients with serum phosphate < 2.5 mg/dL was higher in both the ETV and the TDF groups compared with the control. The multivariate analysis showed that the use of TDF was independently associated with a higher risk of altered excretion of RBP/creatinine (4.4; interquartile range: 1.4 to 14; P = 0.013). Conclusions: We found an independent association between TDF use and altered RBP excretion. This finding indicates subclinical tubular damage. Because tubular dysfunction can precede the decline of renal function, close monitoring of RBP levels in patients with CHB on nucleos(t)ide analog treatment must be performed for early detection of TDF-related renal toxicity. In this study, these differences in tubular function were not associated with concomitant changes in markers of bone turnover.

Schizophrenia is a clinically heterogeneous syndrome affecting multiple dimensions of patients' life. Therefore, its treatment might require a multidimensional approach that should take into account the efficacy (the ability of an intervention to get the desired result under ideal conditions), the effectiveness (the degree to which the intended effect is obtained under routine clinical practice conditions or settings) and the efficiency (value of the intervention as relative to its cost to the individual or society) of any therapeutic intervention. In a first step of the process, a group of 90 national experts from different areas of health-care and with a multidimensional and multidisciplinary perspective of the disease, defined the concepts of efficacy, effectiveness and efficiency of established therapeutic interventions within 7 key dimensions of the illness: symptomatology; comorbidity; relapse and adherence; insight and subjective experience; cognition; quality of life, autonomy and functional capacity; and social inclusion and associated factors. The main conclusions and recommendations of this stage of the work are presented herein.

The management of postmenopausal osteoporosis (PMO) in routine clinical practice differs considerably from guideline recommendations. The objective of our study was to reach a consensus on the management of PMO, considering prevention, diagnosis, treatment and follow-up, according to expert opinion in Spain.A two-round Delphi technique was conducted, including 38 experts. The questionnaire contained 35 sections, each one including 1-10 questions (n = 308) based on a literature review and contributions from the scientific steering committee. Each question was scored by experts from the current (1 = no occurrence, 9 = occurrence in all cases), wish (1 = total rejection; 9 = wish) and prediction (1 = no occurrence at all; 9 = occurs with maximum probability) perspectives. Consensus (wish and prediction perspectives) was considered when ≥75% of experts scored 7-9 (agreement) or 1-3 (disagreement).Overall, consensus was achieved on 75% of questions. While protocols of clinical management and consultation/referral should be followed, their implementation is unlikely. Furthermore, the medical specialties currently involved in PMO management are poorly defined. PMO patients without fracture should be managed (prevention, diagnosis, treatment and follow-up) in both primary care and rheumatology settings; however, experts predicted that only treatment and follow-up will be assumed by these specialties. A multidisciplinary team should be involved in patients with fracture. No assessment tools are usually applied, and prediction indicated that they will not be used.Efforts should be focused on questions with high divergence between wishes and predictions, defining actions that will improve PMO management. Collaboration between scientific societies and health authorities to address the identified opportunities of improvement is proposed.Amgen S.A.

Objective Due to increasing improvement in the diagnosis, evaluation and management of osteoporosis and the development of new tools and drugs, the Spanish Society of Rheumatology (SER) has promoted the development of recommendations based on the best evidence available. These recommendations should be a reference to rheumatologists and other health professionals involved in the treatment of patients with osteoporosis. Methods Recommendations were developed following a nominal group methodology and based on a systematic review. The level of evidence and the degree of recommendation were classified according to the model proposed by the Center for Evidence Based Medicine at Oxford. The level of agreement was established through Delphi technique. Evidence from previous consensus and available clinical guidelines was used. Results We have produced recommendations on diagnosis, evaluation and management of osteoporosis. These recommendations include the glucocorticoid-induced osteoporosis, premenopausal and male osteoporosis. Conclusions We present the SER recommendations related to the biologic therapy risk management.

Two trials have shown that a single 5-mg infusion of zoledronic acid achieves much higher response rates in Paget disease of bone than risedronate. The duration of this effect is unknown. We have conducted an open follow-up of responders from the two trials (152 originally treated with zoledronic acid, 115 with risedronate) out to 6.5 years without further intervention. Endpoints were times to relapse (ie, return of serum total alkaline phosphatase activity to within 20% of the pretreatment value) or loss of response (response = normalization of alkaline phosphatase or 75% or greater reduction in its excess). Bone turnover markers were lower in the zoledronic acid group throughout follow-up, with mean alkaline phosphatase (ALP) remaining within the reference range in these patients, whereas the mean in the risedronate group was above normal from 1 year. Relapse rates were substantially greater in the risedronate group (23 of 115, 20%) than in those treated with zoledronic acid (1 of 152, 0.7%, p

[Background]: Cytokines, specially interleukin (IL)-6, play an important role in the differentiation and activation of osteoclasts and might be involved in osteoblast stimulation in Paget’s disease of bone (PDB). [Objectives]: The aim of this study was to investigate the association of polymorphisms in IL-6, IL-8 and tumor necrosis factors-alpha (TNFA) genes among Spanish patients with PDB. [Methods]: We studied four single nucleotide polymorphisms (−174 G > C IL-6, −251 T > A IL-8, −238 G > A TNFA and −308 G > A TNFA) in 172 PDB patients and 150 healthy controls. Distribution of alleles and pro-inflammatory genotypes were studied for association with the presence of the disease and with clinical and laboratory data, as well as the response to bisphosphonate treatment in PDB patients. [Results]: We found no statistically significant association between genotype and allele distribution of any of the cytokines polymorphism studied and PDB. No association between the clinical and therapeutic characteristics of PDB and the investigated polymorphism were found. [Conclusions]: This study does not support the hypothesis that the analyzed IL6, IL8 and TNFA polymorphism are associated with PDB., This study was partially supported by a grant from the Junta de Castilla y León, Spain (HUS5/04).

Objetivos El objetivo de este estudio ha sido comparar la eficiencia de utilizar el metotrexato subcutaneo (Metoject®) con respecto al metotrexato oral en el manejo de pacientes con AR en Espana. Metodos Se ha realizado un analisis coste-efectividad/utilidad del tratamiento de la AR temprana utilizando un modelo de Markov. El modelo ha permitido estimar la efectividad a largo plazo del tratamiento de la AR en funcion de los datos de la literatura y de la opinion de expertos y combinarlo con informacion de los costes en Espana. El analisis se ha realizado desde la perspectiva del Sistema Nacional de Salud, utilizando un horizonte temporal de 5 anos y de toda la vida del paciente. Todos los costes se expresaron en euros del ano 2009 y se ha utilizado una tasa de descuento del 3%. Resultados La razon de coste (solo costes farmacologicos) por ano de vida ajustado por calidad (AVAC) ganado con Metoject® fue de 25.173�35.807� a los 5 anos y de 19.056�25.351� para toda la vida. Al tener en cuenta los costes directos de la AR se observo que el coste-efectividad a los 5 anos fue de 29.682�42.175�/AVAC ganado y para toda la vida fue de 22.514�29.848�/AVAC ganado. Conclusiones Los costes adicionales de Metoject® respecto a metotrexato oral se verian compensados por su mejora en efectividad, expresada en terminos de AVAC, revelando que Metoject® podria ser un tratamiento costeefectivo para la AR en el Sistema Nacional de Salud segun el umbral asumido en Espana.

Paget's disease of bone (PDB) is a common disorder with a strong genetic component characterized by focal increases in bone turnover, which in some cases is caused by mutations in SQSTM1. To identify additional susceptibility genes, we performed a genome-wide association study in 750 individuals with PDB (cases) without SQSTM1 mutations and 1,002 controls and identified three candidate disease loci, which were then replicated in an independent set of 500 cases and 535 controls. The strongest signal was with rs484959 on 1p13 near the CSF1 gene (P = 5.38 x 10(-24)). Significant associations were also observed with rs1561570 on 10p13 within the OPTN gene (P = 6.09 x 10(-13)) and with rs3018362 on 18q21 near the TNFRSF11A gene (P = 5.27 x 10(-13)). These studies provide new insights into the pathogenesis of PDB and identify OPTN, CSF1 and TNFRSF11A as candidate genes for disease susceptibility.

Objectives The aim of this study was to compare the clinical and economic consequences of using subcutaneous methotrexate (Metoject®) with respect to oral methotrexate in the management of rheumatoid arthritis (RA) in Spain. Methods A cost-effectiveness analysis was performed to compare early treatment of RA using a Markov model. The model allowed us to estimate long term efficacy of RA treatment based on data from the literature and expert opinion, and to combine this data with costs of managing RA in Spain. The perspective of the study was from the National Health System point of view, using a time horizon of 5 years and patient lifetime. All costs were expressed in 2009 euros and a 3% discount rate was applied. Results The cost (only pharmacologic costs) per quality-adjusted life year (QALY) gained with Metoject® went from 25,173 to 35,807 € at 5 years and from 19,056 to 25,351 € for patient lifetime. When direct costs in RA treatment were considered, it was observed that cost-effectiveness at 5 years went from 29,682 to 42,175 €/QALY gained, and for patient lifetime from 22,514 to 29,848 €/QALY gained. Conclusions Additional costs of Metoject® with respect to oral methotrexate would be offset by their improved effectiveness, expressed in QALY, showing that Metoject® could be a cost-effective treatment option for RA in the Spanish Health System assuming a spanish threshold.

Resumen Objetivo Describir las caracteristicas clinicas y epidemiologicas de los sujetos incluidos en el Registro Nacional de Paget. Sujetos y metodo Registro de pacientes con enfermedad osea de Paget (EOP), confirmada radiologicamente, de 25 centros participantes. Se recogieron datos clinicoepidemiologicos (edad, sexo, fecha y manifestaciones al diagnostico y tratamientos), calidad de vida (CV) (cuestionario EuroQol de 5 dimensiones), estado de salud, factores ambientales (profesion, antecedentes de sarampion, contacto con animales, consumo de lacteos, condiciones de la vivienda, lugar de nacimiento y domicilio) y familiares (historia de EOP, procedencia de los ascendientes y numero de hijos). Se realizo una descripcion estadistica de los datos. Resultados El registro incluyo a 602 sujetos con edad media de 62 ± 11 anos con predominio de varones (55%). El 79% de los sujetos presentaba sintomas en el momento del diagnostico, fundamentalmente dolor (83%). El 82% de los sujetos habia recibido tratamiento, principalmente bisfosfonatos, con mas de un farmaco en el 47% de los casos. A pesar del tratamiento, una proporcion importante tenia limitacion de la CV, especialmente relacionada con dolor (64%), movilidad (47%) y ansiedad junto con malestar (33%). La mayor parte de los sujetos habian estado expuestos a situaciones que se consideran factores de riesgo. El 14% de los sujetos tenia historia familiar de EOP y el 1,5% de los sujetos tenia hijos con EOP. Los ascendientes de los casos familiares procedian con mas frecuencia de Avila, Salamanca, Malaga y La Coruna. Conclusiones El dolor y la limitacion de la movilidad disminuyen la CV del sujeto con EOP a pesar del tratamiento. Son frecuentes los antecedentes de exposicion a factores de riesgo.

a b s t r a c t Objectives: To describe the clinical and epidemiological characteristics of patients included in the National Register of Paget's disease. Methods: A Register of patients with Paget disease (PD), radiologically confirmed, and pertaining to 25 hospitals was analyzed. Clinical and epidemiological data were collected, including age, sex, date, and presentations at time of diagnosis, treatment, quality of life (QL) (EuroQol 5D) and perceived health, environmental factors (profession, history of measles, contact with animals, dairy consumption, housing conditions, place of birth and address) and family history (PD history, origin of the ancestors, number of children). We conducted a statistical description of the data. Results: The register included 602 patients with an average age of 62 (11) years and a predominance of male (55%). Of the patients included, 79% showed symptoms at the time of diagnosis, mainly pain (83%); 82% had received treatment, mainly bisphosphonates (47% more than one drug). Despite treatment, a significant proportion had limitations in their QL, especially related to pain (64%), mobility (47%), and anxiety/depression (33%). Most of the patients had been exposed to situations which were considered as risk factors. Of the patients included, 14% had family history of PD and 1.5% had children with PD. The ancestors of the familial cases came more frequently from Avila, Salamanca, La Coruna, and Malaga. Conclusions: The pain and the limitation of mobility decrease the QL of patients with PD despite treatment. Frequently, patients have a history of exposure to risk factors

Fundamento y objetivo: Los estudios sobre la capacidad de los marcadores del remodelado oseo (MRO) para la prediccion de la perdida osea y sobre la correlacion de los MRO con la densidad mineral osea (DMO) han mostrado resultados dispares. Los objetivos del trabajo han sido evaluar la utilidad de los MRO para predecir la perdida de masa osea y estudiar la correlacion entre los MRO y la DMO en las mujeres posmenopausicas recientes. Sujetos y metodo: Seleccionamos al azar a 183 mujeres sanas de 50-55 anos, con menopausia natural en los ultimos 6-36 meses. En suero analizamos fosfatasa alcalina osea (FAO), osteocalcina intacta (OC) y C-telopeptido (sCTx), y en orina, calcio, deoxipiridinolina (DPD) y N-telopeptido (NTx). Realizamos una densitometria osea (L2-L4) basal y otra de control a los 2 anos. El analisis estadistico se ha hecho mediante la t de Student, ANOVA, prueba de x2 y curvas ROC. Resultados: Los MRO correlacionaron con la DMO y permitieron diferenciar entre osteoporosis, osteopenia y masa osea normal, principalmente OC y sCTx (p < 0,001). Segun las curvas ROC, la OC tuvo una sensibilidad del 77,8% y una especificidad del 80,6% para el diagnostico de osteoporosis, mientras que la de sCTx, fue del 83,3 y el 74,5%, respectivamente. En cuanto a la relacion con la perdida osea, solamente hubo diferencia entre el cuartil inferior y el superior de sCTx (p = 0,042). No encontramos asociacion entre recambio oseo alto y perdidas rapidas de masa osea. Conclusiones: Los MRO son de utilidad para la identificacion de mujeres posmenopausicas recientes con osteoporosis y osteopenia, principalmente OC y sCTx, pero respecto a la perdida osea tan solo sCTx tiene un valor predictivo debil.

We conducted the current study to characterize the clinical presentation of primary Sjögren syndrome (SS) in a large cohort of Spanish patients and to determine whether epidemiologic, clinical, and analytical features modulate disease expression. Patients were from the GEMESS Study group, which was formed in 2005 and included 12 Spanish reference centers. By March 2007, the database included 1010 consecutive patients, recruited since 1994, both incident and prevalent cases. The cohort included 937 women and 73 men (ratio, 13:1), with a mean age of 53 years at diagnosis and 59 years at inclusion in the registry. Multivariate analysis showed that male patients had a lower frequency of thyroiditis, Raynaud phenomenon, and antinuclear antibodies. Young-onset patients had a low degree of sicca involvement (xerostomia and parotid enlargement) and a high frequency of immunologic markers (anti-Ro/SS-A and low C4 levels). Patients with disease duration of more than 10 years had a higher prevalence of xerophthalmia, parotid enlargement, lung involvement, and peripheral neuropathy in comparison with incident cases. The subset of patients with anti-Ro/La antibodies had the highest prevalence of most systemic, hematologic, and immunologic alterations (higher frequency of Raynaud phenomenon, altered parotid scintigraphy, positive salivary gland biopsy, peripheral neuropathy, thrombocytopenia, and rheumatoid factor). Hypocomplementemia was associated with a higher frequency of vasculitis and lymphoma, and cryoglobulins with a higher frequency of parotid enlargement, vasculitis, and leukopenia.Epidemiologic, clinical, and analytical features have a significant impact on the clinical presentation of primary SS, influencing the results of the main diagnostic tests, the prevalence and diversity of extraglandular involvement, and the frequency of the main immunologic markers. Primary SS should be considered as a systemic autoimmune disease that can express in many guises beyond sicca involvement.

Background Glucocorticoid (GC) therapy is associated with an increased risk of fractures. The main objective of this study was to determine the prevalence of undiagnosed vertebral fractures in women chronically using GC therapy for autoimmune disorders. We also determined the prevalence of non-vertebral fractures, and investigated whether factors such as quality-of-life and future fracture risk are associated with vertebral/non-vertebral fractures. Methods This was a multicenter cross-sectional study conducted in Spain. All women had rheumatoid arthritis (RA) and/or systemic lupus erythematosus (SLE). Radiological morphometric vertebral fractures were evaluated centrally (Genant semiquantitative method), whereas non-vertebral fractures were not assessed by radiography. Before radiography, patients were asked whether they had vertebral/non-vertebral fractures, hereafter referred to as ‘self-reported’ fractures. Assessment tools included the Disease Activity Score (DAS28), the SF-36 questionnaire, and FRAX®. Results Complete data were obtained for 576 outpatients with RA and/or SLE (83.3 % had RA); mean [SD] age 59.6 [15] years. Of all patients, 6.4 % had self-reported vertebral fractures, whereas 18.9 % had morphometric vertebral fractures (RA: 7.1 % self-reported vs. 20.0 % morphometric; SLE: 3.2 % self-reported vs. 13.7 % morphometric). Non-vertebral fractures were self-reported by 9.8 % of RA and 5.3 % of SLE patients. Low physical functioning was associated with morphometric vertebral fractures (mean [SD] SF-36 score 18.8 [6.0] when present vs. 20.1 [5.9] when absent; p = 0.028) and self-reported non-vertebral fractures (16.7 [5.2] when present vs. 20.1 [5.9] when absent; p

This is an open access article distributed under the terms of the Creative Commons Attribution License., Paget disease of bone (PDB) is a focal bone disorder affecting the skeleton segmentally. The main alteration resides in osteoclasts that increase in size, number and activity. Many osteoclasts have cytoplasmic inclusions that have been associated with protein aggregates, increasing the evidences of a possible deregulation of autophagy in the development of the PDB. Autophagy starts with encapsulation of the target into a double-membrane-bound structure called an >autophagosome.> It has been reported that at least 18 ATG genes (autophagy-related genes) are involved in autophagosome formation. We have studied the distribution of genotypes of the ATG2B rs3759601, ATG16L1 rs2241880, ATG10 rs1864183 and ATG5 rs2245214 polymorphisms in a Spanish cohort of subjects with PDB and compared with healthy subjects. Our results show that being a carrier of the C allele of the ATG16L1 rs2241880 and the G allele of ATG5 rs2245214 polymorphisms were associated with an increased risk of developing PDB, whereas being a carrier of the T allele of ATG10 rs1864183 polymorphism decreased the risk of suffering the disease in our series. This is the first report that shows an association between autophagy and Paget Disease of Bone and requires further confirmation in other series., This work was supported by FIS PI 13/01741 (project belonging to Carlos III Institute, Government of Spain).

Despite the effects of BCR ABL on cell proliferation, no study has compared the proliferative rate of different haematopoietic cell compartments from chronic myeloid leukaemia (CML) with those of normal bone marrow (NBM). We comparatively analysed the cell cycle distribution and BCR/ABL expression in different compartments of BM cells from 15 CML and 11 NBM. Overall, our results showed similar proliferative indices in CML patients and NBM. However, CD34+ myeloid precursors from CML patients displayed an increased proportion of S + G2/M-phase cells (P = 0.04), while no significant differences were found between CML and NBM for other BM cell subsets analysed. In BM cells separated by fluorescence-activated cell sorting, decreasing levels of BCR/ABL mRNA were found from CD34+/CD38+ myeloid precursors to myeloblasts; BCR/ABL expression increased afterwards with a peak at the myelocyte/metamyelocyte stage, decreasing in the more mature band/neutrophil compartment. Unexpectedly, BCR/ABL gene expression showed an inverse correlation with the proportion of S + G2/M-phase cells (R = -0.33; P = 0.04). These results suggest that in CML, BCR/ABL expression is associated with an increased proliferation of CD34+ myeloid haematopoietic progenitor cells but not of other more mature myeloid precursors, as confirmed by the observation of an inverse correlation between the amount of BCR/ABL transcripts and the proportion of S + G2/M-phase cells.

The objective of this article is to evaluate different T-score cut-off points in the calcaneus in order to establish the prevalence of osteoporosis in the general population and to evaluate the clinical value of bone mineral density at the calcaneus as a tool to identify patients with spine or hip osteoporosis. A total of 1455 people (727 women and 728 men) from the Hortega cohort were studied. The densitometric studies were carried out in the calcaneal region using a Peripheral Instantaneous X-ray Imaging (PIXI) Lunar bone densitometer. We established three cut-off points (−1.6, −2.0, −2.5). One-hundred twenty-five patients (67 men with a mean age of 47 ±13 yr and 58 women with a mean age of 66 ±8 yr) from internal medicine outpatient clinics who were undergoing densitometry of the calcaneus, spine, and hip were subsequently studied. The prevalence of osteoporosis in women with a calcaneus T-score −1.6 was 12.4%, which is comparable to the 12.7% obtained with an axial densitometer in a Spanish population. The prevalence in men was 7.8%, with a calcaneus T-score of −1.0 enables the diagnosis of the disease to be excluded, whereas a calcaneus T-score of
