RESUMO
Background and objectives: Diffuse idiopathic skeletal hyperostosis (DISH) is a bone formation disease in which only skeletal signs are considered in classification criteria. The aim of the study was to describe different phenotypes in DISH patients based on clinicoradiological features. Materials and Methods: We evaluated 97 patients who met the Resnick or modified Utsinger classification criteria for DISH and were diagnosed at our hospital from 2004 to 2015. Patients were stratified into: (a) peripheral pattern (PP)-Resnick criteria not met but presenting ≥3 peripheral enthesopathies; (b) axial pattern (AP)-Resnick criteria met but <3 enthesopathies; and (c) mixed pattern (MP)-Resnick criteria met with ≥3 enthesopathies. Statistical analysis was carried out to identify variables that might predict classification in a given group. Results: Fifty-six of the 97 patients included (57.7%) were male and 72.2% fulfilled the Resnick criteria. Applying our classification, 39.7% were stratified as MP, 30.9% as AP and 29.4% as PP. Clinical enthesopathy was reported in 40.2% of patients during the course of the disease. Sixty-eight patients were included in a comparative analysis of variables between DISH patterns. The results showed a predominance of women (p < 0.004), early onset (p < 0.03), hip involvement (p < 0.003) and enthesitis (p < 0.001) as hallmarks of PP. Asymptomatic patients were most frequently observed in AP (28.6%, MP 3.8%, PP 5.0%) while MP was characterized by a more extensive disease. Conclusions: We believe DISH has distinct phenotypes and describe a PP phenotype that is not usually considered. Extravertebral manifestations should be included in the new classification criteria in order to cover the entire spectrum of the disease.

OBJECTIVES: The aim of this study was to assess the clinical and genetic characteristics associated with the presence of peripheral arthritis (PA) at disease onset in patients with ankylosing spondylitis (AS). METHODS: 456 Spanish AS patients, diagnosed according to the modified New York Criteria, who had at least ten years of follow-up since initial disease onset were selected from the National Spondyloarthropathies Registry (REGISPONSER). 18.9% of AS patients initially presented PA. Clinical variables and 384 single nucleotide polymorphisms (SNPs) distributed in 190 genes were analysed. SNP genotyping was performed using the Illumina GoldenGate genotyping platform. Association tests for allele frequencies and for categorical clinical variables were performed by the χ2 test and with the unpaired t-test for continuous variables. p-values of <0.05 were considered statistically significant. RESULTS: AS patients with PA showed an earlier age of disease onset (p=0.021), longer disease duration (p=0.020) and longer duration of AS symptoms from onset (p=0.034) than AS patients without PA. We found significant associations with the presence of PA at disease onset in 14 SNPs located in 10 genes: HLA-DQB2 (rs2857210 and rs9276615), HLA-DOB (rs2857151, rs2621332 and rs1383261), JAK2 (rs7857730), IL-23R (rs11209008 and rs10489630), CYP1B1 (rs1056836), NELL1 (rs8176786), KL (rs564481), and MEFV (rs224204), IL-2RB (rs743777) and IL-1A (rs1800587). CONCLUSIONS: Both clinical and genetic factors are associated with the presence of PA at disease onset in Spanish AS patients. The results suggest that this subset of AS patients with PA at disease onset might have differentiation factors involved in disease pathogenesis.

OBJECTIVES: To study whether disease status at treatment initiation has changed after the issue of the ASAS classification criteria. METHODS: REGISPONSERBIO registers patients with axial spondyloarthritis (axSpA) on biological treatment since 2013. It includes patients starting biological treatment (incident) or already on biological therapies (prevalent). Patients in both groups were compared in terms of: age at disease onset and at treatment start, disease duration, gender, HLA-B27, body mass index (BMI), BASDAI, BASFI, C-reactive protein, ESR, metrological data, ASQoL, WAPAI, extra-articular manifestations, comorbidities, radiological study, type of biological treatment and concomitant treatments. RESULTS: 256 patients were included, of whom 174 (65%) were already on biologic therapy. Compared to incident patients, prevalent patients started treatment with longer disease duration (15 vs. 8.6 years; p<0.001), a higher proportion of them were men (83% vs. 67%; p=0.01), a smaller proportion of them showed non-radiographic axial spondylarthritis (nr-axSpA)(17% vs. 32%; p<0.01), and a higher proportion had HLAB27 (85% vs. 73%; p=0.02). There were no statistically significant differences in terms of disease activity, degree of disability, quality of life, or prevalence of extra-articular manifestations. CONCLUSIONS: Data suggest that, after the issue of the new classification criteria for SpA, biological therapy is being administered earlier than previously in SpA patients and in a higher proportion of patients with nr-axSpA. However, this change in prescribing profile, apparently, has not caused an over-treatment, as patients do not seem to have a lower disease burden than prior to the issue of the criteria.

The aim of this study was to assess nailfold capillaroscopic (NC) findings in patients with primary Sjögren's syndrome (PSS) with and without Raynaud's phenomenon (RP) as well as in the presence of positive anti-SSA/Ro and anti-SSB/La antibodies. Videocapillaroscopy was performed in 150 patients with PSS. Data collected included demographics, presence of RP, PSS symptoms, antinuclear antibodies, rheumatoid factor, anti-Ro, anti-La, anti-CCP, salivary scintigraphy, labial biopsy, and NC findings. RP was present in 32% of PSS, keratoconjunctivitis sicca in 91%, oral xerosis in 93%, and skin or genital xerosis in 53%. In patients with positive anti-SSA/Ro (75%) and positive anti-SSB/La (40%), NC showed normal findings in 53% of cases and non-specific in 36%. In patients with PSS, NC was normal in 51% of cases and non-specific in 34%. Scleroderma pattern was found in 14 patients. RP associated with PSS had non-specific capillaroscopy in 40% of cases (p = 0.1). Pericapillary haemorrhages (p = 0.06) and capillary thrombosis (p = 0.2) were not increased, but more dilated capillaries were detected in 48% of cases. Patients with positive anti-Ro and/or anti-La have not a distinct NC profile. Patients with RP associated with PSS had more dilated capillaries, but neither pericapillary haemorrhages nor capillary thrombosis was observed.

OBJECTIVE: The aim of this study was to develop a genetic prognostic tool to predict radiographic progression towards severe disease in primary knee OA (KOA) patients. METHODS: This investigation was a cross-sectional, retrospective, multicentric association study in 595 Spanish KOA patients. Caucasian patients aged ≥40 years at the time of diagnosis of primary KOA of Kellgren-Lawrence grade 2 or 3 were included. Patients who progressed to Kellgren-Lawrence score 4 or who were referred for total knee replacement within 8 years after diagnosis were classified as progressors to severe disease. Clinical variables of the initial stages of the disease (gender, BMI, age at diagnosis, OA in the contralateral knee, and OA in other joints) were registered as potential predictors. Single nucleotide polymorphisms and clinical variables with an association of P < 0.05 were included in the multivariate analysis using forward logistic regression. RESULTS: A total of 23 single nucleotide polymorphisms and the time of primary KOA diagnosis were significantly associated with KOA severe progression in the exploratory cohort (n = 220; P < 0.05). The predictive accuracy of the clinical variables was limited: area under the curve (AUC) = 0.66. When genetic variables were added to the clinical model (full model), the prediction of KOA progression was significantly improved (AUC = 0.82). Combining only genetic variables (rs2073508, rs10845493, rs2206593, rs10519263, rs874692, rs7342880, rs780094 and rs12009), a predictive model with good accuracy was also obtained (AUC = 0.78). The predictive ability for KOA progression of the full model was confirmed on the replication cohort (two-sample Z-test; n = 62; P = 0.190). CONCLUSION: An accurate prognostic tool to predict primary KOA progression has been developed based on genetic and clinical information from OA patients.

Dactylitis is a clinical concept that corresponds to the swelling of the whole finger or toe giving a sausage appearance. Although it can be observed in different diseases, it is a distinctive clinical feature of psoriatic arthritis and is associated with a poor prognosis. Ultrasound has made it possible to improve our understanding of the pathogenesis of psoriatic arthritis dactylitis, identifying associated structural alterations, namely, flexor tenosynovitis, subcutaneous tissue edema, pulley inflammation with thickening and intra-pulley Doppler signals, extensor paratenonitis, synovitis, pericapsular bone formation, and flexor enthesitis. Given its complexity, a consensus has yet to be reached on an ultrasound-based definition of dactylitis. In addition, enthesitis is one of the characteristic features of spondyloartritis. Enthesitis, like dactylitis, is among the clinical manifestations in the Assessment of SpondyloArthritis international Society classification criteria for both axial and peripheral spondyloartritis and is a key feature for classifying psoriatic arthritis with the Classification criteria for Psoriatic Arthritis criteria. Ultrasonography is a very useful tool for exploring the enthesis. We have a good sonographic definition, although ultrasound findings do not always allow us to differentiate between mechanical or inflammatory lesions. Elementary lesions that characterize enthesopathy are hypoechogenicity at the enthesis, thickened enthesis, calcification/enthesophyte at enthesis, erosion at enthesis, and Doppler signal at enthesis. Different composite indices have been proposed in order to classify spond yloarthropathies. This article reviews the evaluation of dactylitis and enthesitis from the sonographic perspective.
RESUMO
Diffuse idiopathic skeletal hyperostosis is a bone disease characterized by ossification of spinal ligaments and peripheral entheses. Currently, we still use the classic classification criteria that do not include extraspinal manifestations. A number of authors agree on the need to revise them. We present 3 patients in which a diagnosis of diffuse idiopathic skeletal hyperostosis could not be established if we apply those criteria, but they have fully compatible clinical and radiological manifestations of hyperostotic disease.

BACKGROUND AND OBJECTIVE: The study is aimed at improving our knowledge about the functional impairment of the psoriatic arthritis through a multicentral series. PATIENTS AND METHOD: We have designed a transversal and multicentral study (centers of the same geographical area), including 343 patients with psoriatic arthritis. Eight medical centers have participated. Patients have been divided depending on the assistential level where they are visited. We have collected the following data: sex, age, assistential level, duration of psoriasis and arthritis, age at onset of psoriasis and arthritis, clinical form, ARA functional impairment, number of tender and swollen joints, presence of dactylitis, distal interphalangeal affection, axial involvement, ostheolisis or nail lesions, erithrocyte sedimentation rate (ESR), C-reactive protein, hemoglobine, leucocites, platelets, HLA-B27 and rheumatoid factor. RESULTS: 7.14% of the patients were significatly disabled (ARA functional class III and IV). 30.32% were patients visited in a primary assistential level, 30.90% in a secondary assistential level and 38.78% a tertiary and universitary hospital. We found statistically significant correlation between III and IV functional classes and age, assistential level, ostheolisis, corticoid treatment, ESR, leucocites, platelets and number of tender joints. CONCLUSIONS: We find a better functional capacity in our patients than in other studies. The inclusion of patients from different assistential levels instead of just patients visited in a tertiary hospital might be the cause of this difference.

OBJECTIVE: to compare the short-term efficacy and safety of rituximab (RTX) therapy versus anti-TNF in rheumatoid arthritis (RA) patients after discontinuation of a first anti-TNF agent. METHODS: prospective observational multicenter study in the clinical practice setting, involving patients with severe RA refractory to a first anti-TNF agent, who received either RTX or a second anti-TNF (2TNF), comparing the efficacy endpoints, EULAR response (Good/Moderate) and safety at 6 months. RESULTS: 103 patients enrolled, 82 completed 6-month follow-up, 73.7% women. Baseline data for RTX and 2TNF groups, respectively: TJC, 8.6 and 6.6; SJC, 8.8 and 7.5; DAS28 score, 5.45 (±1.28) and 5.18 (±1.21) (p=0.048), ESR, 41 and 38.7mmHg; and HAQ, 1.2 and 1.0. Improvement was observed in all parameters, with no significant differences (except for a more marked reduction in ESR with RTX). There were no serious adverse events. CONCLUSIONS: RTX use as second-line therapy after anti-TNF failure led to improvements in the efficacy and functional variables at 6 months, with no serious adverse events. These results were comparable to those observed in patients who used a second anti-TNF agent in the same clinical scenario.

OBJECTIVE: Diagnosis and therapy of patients with early onset rheumatoid arthritis (RA) is influenced by accessibility to specialized care devices. We attempted to analyze the impact of their availability. METHODS: We analyzed time related to diagnosis delay measuring: 1) Time from first clinical symptoms to the first visit with the Rheumatologist; 2) Time from referral to the first visit of Rheumatology; 3) Time between first symptom until final diagnosis; 4) time between first symptom until the initiation of the first disease-modifying antirheumatic drug (DMARD). The presence of these 6 rheumatology devices was defined: 1) early arthritis monographic clinics, 2) RA monographic clinics, 3) Mechanisms for fast programming, 4) Algorithms for referral from primary care (PC), 5) rheumatology consultation services in PC and 6) consulting services in PC. RESULTS: The mean time from onset of symptoms to diagnosis or the establishment of a DMARD in RA patients in Catalonia is very long (11 months). Patients seen in rheumatology devices such as RA monographic clinics, rheumatology consultation in PC and specially in early arthritis clinics are treated early with DMARDs. CONCLUSION: the existence of monographic clinics or consulting in primary care centers is essential to improve early care of RA patients.

OBJECTIVE: To describe a large series of patients with mutilans/resorptive arthritis (AM) of a representative population of patients with psoriatic arthritis (PsA) and analyze the associated variables. METHODS: Multicenter cross-sectional study of consecutive patients affected by PsA in 8 centers. In patients with swelling or deformity of the hands or feet we performed an anteroposterior rx. The patient was affected by AM if erosive disorder affecting both articular surfaces completely was present. RESULTS: Of the 360 patients studied, 24 had PsA and AM (6.7%). The duration of their disease was significantly higher, and they exhibited a worse functional capacity as well as more DIP joint affection (P<.05). 30% had radiological changes indistinguishable from nodular osteoarthritis. CONCLUSIONS: AM in PA is associated with a worse functional capacity. Its possible association with nodular hand osteoarthritis deserves further study.
