Objectives To assess efficacy and safety of biologic therapy (BT) in neurobehcet's disease (NBD) refractory to glucocorticoids and at least one conventional immunosuppressive drug. Methods Open-label, national, multicentre study. NBD diagnosis was based on the International Consensus Recommendation criteria. Outcome variables were efficacy and safety. Main efficacy outcome was clinical remission. Other outcome variables analysed were glucocorticoid-sparing effect and improvement in laboratory parameters. Results We studied 41 patients [21 women; age 40.6 (10.8) years]. Neurological damage was parenchymal (n = 33, 80.5%) and non-parenchymal (n = 17, 41.5%). First BTs used were infliximab (n = 19), adalimumab (n = 14), golimumab (n = 3), tocilizumab (n = 3) and etanercept (n = 2). After 6 months of BT, neurological remission was complete (n = 23, 56.1%), partial (n = 15, 37.6%) and no response (n = 3, 7.3%). In addition, median (IQR) dose of oral prednisone decreased from 60 (30-60) mg/day at the initial visit to 5 (3.8-10) mg/day after 6 months (P < 0.001). It was also the case for mean erythrocyte sedimentation rate [31.5 (25.6)-15.3 (11.9) mm/1st h, P = 0.011] and median (IQR) C-reactive protein [1.4 (0.2-12.8) to 0.3 (0.1-3) mg/dl, P = 0.001]. After a mean follow-up of 57.5 months, partial or complete neurological remission persisted in 37 patients (90.2%). BT was switched in 22 cases (53.6%) due to inefficacy (n = 16) or adverse events (AEs) (n = 6) and discontinued due to complete prolonged remission (n = 3) or severe AE (n = 1). Serious AEs were observed in two patients under infliximab treatment. Conclusions BT appears to be effective and relatively safe in refractory NBD.

Objectives: To analyse current status, control and impact of RA on patients' lives as well as the management of RA symptoms. Methods: A structured anonymous online questionnaire was designed and sent to patients with RA, aged 18 years or above living in Spain. Participants were invited though different strategies: 1) ConArtritis and related patients associations; 2) Patients participating in the platform www.in-pacient.es; 3) Links from ConArtritis website and open social networks. Sociodemographic and clinical variables, as well as others related to the objectives were collected. A descriptive analysis was performed. Results: We analysed 882 RA patients, 89% women, with a median age of 52 years, 31.9% disease duration < 5 years. They reported a mean pain and patient global disease score (0-10) of 5.1 and 4.9 respectively. The rate of patients with many difficulties or inability to perform daily tasks varied from 6.4% to 49.2%. Based on the activity index 56.8% of patients reported high activity. We found a great or severe impact on the emotional well-being in 31.5% of patients, and of 29.2% in the workplace or academic setting. A total of 87.9% are taking some medication for RA, and 17.3% are little/not satisfied with them. In addition, 67.1% take conventional synthetic disease modifying drugs (DMARDs), and 45.9% biological therapies including biosimilars and small molecules. Conclusions: The current impact of RA on patients' daily lives remains very high. A significant number of patients are not taking DMARDs (conventional synthetic and/or biologics) despite high activity.(c) 2020 Elsevier Espan tilde a, S.L.U. and Sociedad Espan tilde ola de Reumatologi acute accent a y Colegio Mexicano de Reumatologi acute accent a.

Gout is characterized by monosodium urate (MSU) crystal deposits in and within joints. These deposits result from persistent hyperuricaemia and most typically lead to recurrent acute inflammatory episodes (gout flares). Even though some aspects of gout are well characterized, uncertainties remain; this upcoming decade should provide further insights into many of these uncertainties. Synovial fluid analysis allows for the identification of MSU crystals and unequivocal diagnosis. Non-invasive methods for diagnosis are being explored, such as Raman spectroscopy and imaging modalities. Both ultrasound and dual-energy computed tomography (DECT) allow the detection of MSU crystals; this not only provides a mean of diagnosis, but also has furthered gout knowledge defining the presence of a preclinical deposition in asymptomatic hyperuricaemia. Scientific consensus establishes the beginning of gout as the beginning of symptoms (usually the first flare), but the concept is currently under review. For effective long-term gout management, the main goal is to promote crystal dissolution treatment by reducing serum urate below 6 mg/dL (or 5 mg/dL if faster crystal dissolution is required). Current urate-lowering therapies' (ULTs) options are limited, with allopurinol and febuxostat being widely available, and probenecid, benzbromarone, and pegloticase available in some regions. New xanthine oxidase inhibitors and, especially, uricosurics inhibiting urate transporter URAT1 are under development; it is probable that the new decade will see a welcomed increase in the gout therapeutic armamentarium. Cardiovascular and renal comorbidities are common in gout patients. Studies determining whether optimal treatment of gout will positively impact these comorbidities are currently lacking, but will hopefully be forthcoming. Overall, the single change that will most impact gout management is greater uptake of international rheumatology society recommendations. Innovative strategies, such as nurse-led interventions based on these recommendations have recently demonstrated treatment success for people with gout.

OBJECTIVE: To estimate the prevalence of gout in Spain. METHODS: Cross-sectional, population-based study of people aged 20 years or older. First, randomly selected individuals were contacted by telephone and rheumatic disease screening questionnaires were conducted. If the first screening was positive, medical records were then reviewed and/or a phone questionnaire was conducted by a rheumatologist, followed by an appointment if necessary. Newly diagnosed cases had to fulfil the ACR/EULAR 2015 criteria. To calculate the prevalence and its 95% CI, the sample design was taken into account and weighing was calculated according to age, sex and geographic origin. RESULTS: In all, 4916 individuals were included, 1361 had a positive screening result for gout (59 of them reported a prior diagnosis). Of these, 51 were classified as missing and 95 were classified as gout cases. An additional case was detected through a positive screening for fibromyalgia and Sjögren's syndrome, although a previous gout diagnosis was confirmed by a review of the medical records. Of the 96 gout cases, 31 (32%) were de novo diagnoses. The estimated weighted prevalence of gout was 2.4% (95% CI 1.95-2.95), with a higher prevalence in men (4.55% [95%CI 3.65-5.65]) than women (0.38% [95%CI 0.19-0.76]). CONCLUSION: EPISER2016 is the first population-based study to estimate the prevalence of gout in Spain. Undiagnosed patients accounted for a substantial proportion of cases, highlighting the need for population-approaches when estimating the prevalence of infra-diagnosed diseases. Reliable national approaches are key to obtaining accurate estimates of diseases to better aid healthcare and workforce planning.

Objective: To compare the efficacy and safety of TCZ in monotherapy (TCZ(MONO)) vs. combined with conventional immunosuppressive drugs (TCZ(COMBO)) in Giant Cell Arteritis (GCA) in a clinical practice scenario. Methods: Multicenter study of 134 patients with refractory GCA. Patients on TCZ(MONO) (n = 82) were compared with those on TCZ(COMBO) (n = 52). Drugs were methotrexate (MTX) (n = 48), azathioprine (n = 3), and lefluno-mide (n = 1). The main outcomes were: prolonged remission (normalization of clinical and laboratory parameters for at least 6 months) and the number of relapses. Results: Patients on TCZ(COMBO) were younger (68.8 +/- 8.0 vs 71.2 +/- 9.0 years; p = 0.04), with a trend to a longer GCA duration (median [IQR],18.5 [6.25-34.0] vs. 13.0 [7.75-33.5] months; p = 0.333), higher C-reactive protein (CRP) levels (2.1[1-4.7] vs 1.2 [0.2-2.4] mg/dL; p = 0.003), and more prevalence of extra-cranial large vessel vasculitis (LVV) (57% vs. 34.1%; p = 0.007). In both groups, rapid and sustained improvement was observed. Despite the longer GCA duration, and the higher CRP levels and prevalence of LVV in the TCZ(COMBO), the improvement was similar in both groups at 12 months. Moreover, in the TCZ(COMBO) group, prolonged remission was significantly higher at 12-month. Relapses and serious adverse events were similar in both groups. Conclusion: In clinical practice, TCZ in monotherapy or combined with conventional immunosuppressive agents is effective and safe in patients with GCA. Nevertheless, the addition of immunosuppressive drugs, usually MTX, seems to allow a higher rate of prolonged remission, even in patients with a longer GCA duration, more extra-cranial LVV involvement, and higher acute-phase reactants.

BACKGROUND: Dietary supplements are frequently used for the treatment of several medical conditions, both prescribed by physicians or self administered. However, evidence of benefit and safety of these supplements is usually limited or absent. OBJECTIVES: To assess the efficacy and safety of dietary supplementation for people with chronic gout. SEARCH METHODS: We performed a search in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and CINAHL on 6 June 2013. We applied no date or language restrictions. In addition, we performed a handsearch of the abstracts from the 2010 to 2013 American College of Rheumatology (ACR) and European League against Rheumatism (EULAR) conferences, checked the references of all included studies and trial registries. SELECTION CRITERIA: We considered all published randomised controlled trials (RCTs) or quasi-RCTs that compared dietary supplements with no supplements, placebo, another supplement or pharmacological agents for adults with chronic gout for inclusion. Dietary supplements included, but were not limited to, amino acids, antioxidants, essential minerals, polyunsaturated fatty acids, prebiotic agents, probiotic agents and vitamins. The main outcomes were reduction in frequency of gouty attacks and trial participant withdrawal due to adverse events. We also considered pain reduction, health-related quality of life, serum uric acid (sUA) normalisation, function (i.e. activity limitation), tophus regression and the rate of serious adverse events. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS: We identified two RCTs (160 participants) that fulfilled our inclusion criteria. As these two trials evaluated different diet supplements (enriched skim milk powder (SMP) and vitamin C) with different outcomes (gout flare prevention for enriched SMP and sUA reduction for vitamin C), we reported the results separately.One trial including 120 participants, at moderate risk of bias, compared SMP enriched with glycomacropeptides (GMP) with unenriched SMP and with lactose over three months. Participants were predominantly men aged in their 50's who had severe gout. The frequency of acute gout attacks, measured as the number of flares per month, decreased in all three groups over the study period.The effects of enriched SMP (SMP/GMP/G600) compared with the combined control groups (SMP and lactose powder) at three months in terms of mean number of gout flares per month were uncertain (mean ± standard deviation (SD) flares per month: 0.49 ± 1.52 in SMP/GMP/G60 group versus 0.70 ± 1.28 in control groups; mean difference (MD) -0.21, 95% confidence interval (CI) -0.76 to 0.34; low-quality evidence). The number of withdrawals due to adverse effects was similar in both groups although again the results were imprecise (7/40 in SMP/GMP/G600 group versus 11/80 in control groups; risk ratio (RR) 1.27, 95% CI 0.53 to 3.03; low-quality evidence). The findings for adverse events were also uncertain (2/40 in SMP/GMP/G600 group versus 3/80 in control groups; RR 1.33, 95% CI 0.23 to 7.66; low-quality evidence). Gastrointestinal events were the most commonly reported adverse effects. Pain from self reported gout flares (measured on a 10-point Likert scale) improved slightly more in the SMP/GMP/G600 group compared with controls (mean ± SD reduction -1.97 ± 2.28 points in SMP/GMP/G600 group versus -0.94 ± 2.25 in control groups; MD -1.03, 95% CI -1.96 to -0.10; low-quality evidence). This was an absolute reduction of 10% (95% CI 20% to 1% reduction), which may not be of clinical relevance. Results were imprecise for the outcome improvement in physical function (mean ± SD Health Assessment Questionnaire (HAQ)-II (scale 0 to 3, 0 = no disability): 0.08 ± 0.23 in SMP/GMP/G60 group versus 0.11 ± 0.31 in control groups; MD -0.03, 95% CI -0.14 to 0.08; low-quality evidence). Similarly, results for sUA reduction were imprecise (mean ± SD reduction: -0.025 ± 0.067 mmol/L in SMP/GMP/G60 group versus -0.010 ± 0.069 in control groups; MD -0.01, 95% CI -0.04 to 0.01; low-quality evidence). The study did not report tophus regression and health-related quality of life impact.One trial including 40 participants, at moderate to high risk of bias, compared vitamin C alone with allopurinol and with allopurinol plus vitamin C in a three-arm trial. We only compared vitamin C with allopurinol in this review. Participants were predominantly middle-aged men, and their severity of gout was representative of gout in general. The effect of vitamin C on the rate of gout attacks was not assessed. Vitamin C did not lower sUA as much as allopurinol (-0.014 mmol/L in vitamin C group versus -0.118 mmol/L in allopurinol group; MD 0.10, 95% CI 0.06 to 0.15; low-quality evidence). The study did not assess tophus regression, pain reduction or disability or health-related quality of life impact. The study reported no adverse events and no participant withdrawal due to adverse events. AUTHORS' CONCLUSIONS: While dietary supplements may be widely used for gout, this review has shown a paucity of high-quality evidence assessing dietary supplementation.

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: The aim of this study was to estimate the prevalence of ankylosing spondylitis (AS) in Spain.Method: This is a cross-sectional, population-based study of people aged 20 years or older in Spain. Randomly selected individuals were contacted by telephone and rheumatic disease screening was performed. If the first screening was positive, medical records were then reviewed and/or a telephone questionnaire was conducted by a rheumatologist, followed by an appointment if necessary. Cases had to fulfil the modified New York (mNY) criteria.Results: In total, 4916 individuals were included, of whom 355 had a positive screening result for AS. Of these, 11 were classified as AS. An additional individual who reported a prior diagnosis of rheumatoid arthritis had a diagnosis of AS confirmed on review of the medical records. Estimated prevalence was 0.26% (95% CI 0.14-0.49).Conclusion: EPISER2016 is the first population-based study to estimate the prevalence of AS in Spain, which has been estimated as being similar to that in other European countries.

Objective To summarise the literature on the assessment of competences in postgraduate medical training. Methods A systematic literature review was performed within a EULAR taskforce on the assessment of competences in rheumatology training and other related specialities (July 2019). Two searches were performed: one search for rheumatology and one for related medical specialities. Two reviewers independently identified eligible studies and extracted data on assessment methods. Risk of bias was assessed using the medical education research study quality instrument. Results Of 7335 articles in rheumatology and 2324 reviews in other specialities, 5 and 31 original studies were included, respectively. Studies in rheumatology were at variable risk of bias and explored only direct observation of practical skills (DOPS) and objective structured clinical examinations (OSCEs). OSCEs, including clinical, laboratory and imaging stations, performed best, with a good to very good internal consistency (Cronbach's alpha=0.83-0.92), and intrarater reliability (r=0.80-0.95). OSCEs moderately correlated with other assessment tools: r=0.48 vs rating by programme directors; r=0.2-0.44 vs multiple-choice questionnaires; r=0.48 vs DOPS. In other specialities, OSCEs on clinical skills had a good to very good inter-rater reliability and OSCEs on communication skills demonstrated a good to very good internal consistency. Multisource feedback and the mini-clinical evaluation exercise showed good feasibility and internal consistency (reliability), but other data on validity and reliability were conflicting. Conclusion Despite consistent data on competence assessment in other specialities, evidence in rheumatology is scarce and conflicting. Overall, OSCEs seem an appropriate tool to assess the competence of clinical skills and correlate well with other assessment strategies. DOPS, multisource feedback and the mini-clinical evaluation exercise are feasible alternatives.

Purpose of review Calcium pyrophosphate crystal disease (CPPD) may be considered a neglected disorder, common in clinics and wards, but not receiving enough attention since the time it was recognized as a disease entity. This review aims to highlight the advances occurred in recent years in terms of imaging of CPPD, and their potential aid in diagnosing CPPD. Recent findings The main advances in CPPD imaging have occurred with ultrasound and computed tomography. Ultrasound has been shown as more sensitive than conventional radiography in detecting chondrocalcinosis. OMERACT definitions of ultrasound signs of CPPD have been provided; validations process is still ongoing. Computed tomography has been used to assess CPPD at the spine. Some studies suggest that dual-energy scans could accurately detect chondrocalcinosis and discriminate from other calcified structures. Ultrasound and computed tomography may have a role in CPPD detection, though the specifics are still unclear. It remains necessary to have studies comparing them with synovial fluid analysis for crystals in a clinical scenario.

In the field of rheumatic and musculoskeletal diseases, no other condition has evolved so significantly since the mid-1950s as gout. In this period, the cause of gout has been firmly established; the close relationship with other conditions clarified; a rapid, unequivocal diagnostic test established; and agents effective in dissolving monosodium urate crystals and controlling inflammation made widely available. All these insights have ultimately led to deem gout as curable, an end point formerly considered out of reach. Unfortunately, diagnosis and management of gout in clinical practice have not paralleled the scientific advances and remain far from established quality standards. This paradox is the topic of the present review article, intending to increase the widespread interest of clinicians in gout.
