Objectives The aims of this study were to establish delay times from articular symptoms onset to first rheumatologist consultation, rheumatoid arthritis (RA) diagnosis, and treatment initiation with disease-modifying antirheumatic drug (DMARD) therapy and to assess the impact of delayed diagnosis on structural damage. Methods This was an observational cohort study. Rheumatoid arthritis adult patients treated in a private health system between January 1, 1996, and December 31, 2016, were included. Electronic medical records were reviewed to obtain clinical and demographic data, dates of first disease symptom, diagnosis, and date of first treatment with DMARDs. Physical function (Health Assessment Questionnaire) and structural damage (Sharp score modified by van der Heijde) were also assessed. Results Two hundred forty-six patients (81% female), with a mean age of 67.25 (standard deviation [SD], 14.53) years, were included. At the end of follow-up period, median Health Assessment Questionnaire (n = 145) and radiological scores (n = 171) were 0.125 (interquartile range, 0-0.87) and 15 (interquartile range, 6-33), respectively. A mean of 9.2 (SD, 20) months (median, 3 months) elapsed from the first disease symptom to rheumatologist consultation, 14.2 (SD, 24) months (median, 4.8 months) to RA diagnosis, and 16.9 (SD, 25.4) months (median, 7 months) to treatment initiation with DMARDs. Significantly greater structural damage was found in patients with a diagnosis delay of more than 12 months (n = 70) (p = 0.0325). Conclusions Despite good access to medical consultation in a private health system, there is still a delay to RA diagnosis and to start pharmacological therapy. A delay of more than 12 months was significantly associated with greater radiological damage after 5 years of follow-up.

Objectives The aims of this study were to compare learned helplessness (LH) and perceived self-efficacy (SE) in patients with fibromyalgia (FM) and rheumatoid arthritis (RA) and to assess their correlation with functional disability, level of perceived pain, and fatigue. Methods This multicenter, cross-sectional study included consecutive patients (aged ≥18 years) with RA, according to the 2010 American College of Rheumatology/European League Against Rheumatism criteria, and FM, according to 2010 American College of Rheumatology criteria. Learned helplessness was measured by the Rheumatology Attitude Index, Spanish version; SE with the Arthritis Self-efficacy Scale, Spanish version; functional capacity with the Health Assessment Questionnaire (HAQ), Argentine version; depression with Center for Epidemiological Studies-Depression Scale 7-item version and perceived pain and fatigue by the visual analog scale. Disease activity was measured by the Clinical Disease Activity Index (CDAI) and disease impact with the Fibromyalgia Impact Questionnaire (FIQ). Results A total of 215 patients, 100 with FM and 115 with RA, were included. Mean age was 59 (SD, 14) years and 58 (SD, 13) years for FM and RA, patients respectively. Whereas LH and depression were significantly higher, SE was significantly lower in FM patients. We found a positive correlation between LH and HAQ, pain, depression, fatigue, FIQ, and CDAI in FM and RA patients. We observed a negative correlation between SE and HAQ, pain, depression, fatigue, FIQ (FM), and CDAI (RA) in both groups. Conclusions Both LH and SE correlate significantly with functional capacity, perceived pain, disease activity, and disease impact in RA and FM patients. Learned helplessness was higher in patients with active disease or high disease impact, as opposed to those in remission or with low disease impact, and the reverse was true for SE. Patients with FM had significantly more LH, pain, fatigue, and depression and less SE compared with those with RA.

Objectives The level of detail included when describing nailfold videocapillaroscopy (NVC) methods varies among research studies, making interpretation and comparison of results challenging. The overarching objective of the present study was to seek consensus on the reporting standards in NVC methodology for clinical research in rheumatic diseases and to propose a pragmatic reporting checklist. Methods Based on the items derived from a systematic review focused on this topic, a three-step web-based Delphi consensus on minimum reporting standards in NVC was performed among members of the European League against Rheumatism (EULAR) Study Group on Microcirculation in Rheumatic Diseases and the Scleroderma Clinical Trials Consortium. Results A total of 319 articles were selected by the systematic review, and 46 items were proposed in the Delphi process. This Delphi exercise was completed by 80 participants from 31 countries, including Australia and countries within Asia, Europe, North America and South America. Agreement was reached on items covering three main areas: patient preparation before NVC (15 items), device description (5 items) and examination details (13 items). Conclusion Based on the available evidence, the description of NVC methods was highly heterogeneous in the identified studies and differed markedly on several items. A reporting checklist of 33 items, based on practical suggestions made (using a Delphi process) by international participants, has been developed to provide guidance to improve and standardize the NVC methodology to be applied in future clinical research studies.

Objective To evaluate fenebrutinib, an oral and highly selective noncovalent inhibitor of Bruton's tyrosine kinase (BTK), in patients with active rheumatoid arthritis (RA). Methods Patients with RA and an inadequate response to methotrexate (MTX) (cohort 1; n = 480) were randomized to receive fenebrutinib (50 mg once daily, 150 mg once daily, or 200 mg twice daily), adalimumab (40 mg every other week), or placebo. Patients with RA and an inadequate response to tumor necrosis factor inhibitors (cohort 2; n = 98) received fenebrutinib (200 mg twice daily) or placebo. Both cohorts continued MTX therapy. Results In cohort 1, the percentages of patients in whom American College of Rheumatology 50% improvement criteria (ACR50) was achieved at week 12 were similar in the fenebrutinib 50 mg once daily and placebo groups, and were higher in the fenebrutinib 150 mg once daily group (28%) and 200 mg twice daily group (35%) than in the placebo group (15%) (P = 0.016 and P = 0.0003, respectively). Fenebrutinib 200 mg twice daily and adalimumab (36%) were comparable (P = 0.81). In cohort 2, ACR50 was achieved in more patients receiving fenebrutinib 200 mg twice daily (25%) than placebo (12%) (P = 0.072). The most common adverse events in the fenebrutinib groups included nausea, headache, anemia, and upper respiratory tract infections. Fenebrutinib had significant effects on myeloid and B cell biomarkers (CCL4 and rheumatoid factor). Fenebrutinib and adalimumab caused overlapping as well as distinct changes in B cell and myeloid biomarkers. Conclusion Fenebrutinib demonstrates efficacy comparable to adalimumab in patients with an inadequate response to MTX, and safety consistent with existing immunomodulatory therapies for RA. These data support targeting both B and myeloid cells via this novel mechanism for potential efficacy in the treatment of RA.

Objectives. To examine the characteristics of our patients with limited systemic sclerosis (lSSc) for differences between Barnett Type 1 (sclerodactyly only) and Type 2 or intermediate (acrosclerosis-distal but may reach up to elbows and/or knees plus face) subsets.Methods. Records of patients between January 1, 2000, and December 31, 2011, with SSc or those with anti-Scl-70, anticentromere, or antinucleolar antibodies were reviewed. Only cases fulfilling ACR 1980 criteria were included and classified as diffuse or limited according to LeRoy’s criteria. Limited SSc was separated into sclerodactyly and acrosclerosis (Barnett’s Types 1 and 2).Results. 234 SSc patients (216 females) fulfilled criteria. Female/male ratio was 12 : 1; 24% had dSSc and 76% lSSC (64% Type 1 and 12% Type 2). Total follow-up was 688 patient-years. Within lSSC, the Type 2 group had significantly shorter duration of Raynaud’s and more anti-Scl-70 and less anticentromere antibodies. In particular, interstitial lung disease (ILD) was significantly more prevalent in Type 2 group and similar to Type 3.Conclusions. These results appear to confirm that extension of skin involvement within limited SSc may identify two different subsets with clinical and serologic characteristics.

Polymyositis (PM) and dermatomyositis (DM) are infrequent diseases. Data on incidence and prevalence are scarce and conflicting. There are no such data in Latin America and in Argentina in particular.We undertook to examine the incidence and prevalence of PM/DM in the prepaid health maintenance organization (HMO) of our hospital, in the city of Buenos Aires.Members of the HMO between January 1999 and June 2009 were identified from medical records of patients followed up by us at the HMO. Incident cases and prevalence were calculated at the end of the period.During the study period, 146,747 persons contributed a total of 937,902.6 person-years (mean age was 46.6 [SD, 18.4] years, and 59% were female). Ten incident cases were detected, 7 women and 3 men with a global incidence rate (IR) of 1.07 per 100,000 person-years (95% confidence interval [CI], 0.5-1.84). Three subjects had DM with an IR of 0.32 per 100,000 person-years (95% CI, 0.1-0.99), and 7 had PM with an IR of 0.75 per 100,000 person-years (95% CI, 0.35-0.16). On June 1, 2009, 17 prevalent cases were detected, with a mean age of 48.9 (SD, 17.7) years; 76% were female, representing a prevalence of 17.4 per 100,000 persons (95% CI, 10.1-27.8). Among the 17 patients with idiopathic inflammatory myopathy, 10 patients had DM, with a prevalence of 10.22 per 100,000 persons (95% CI, 4.9-18.8), and 7 had PM (prevalence, 7.2 per 100,000 persons [95% CI, 2.9-14.7]).It is difficult to compare studies from different populations and using different ascertainment techniques. These first data from Latin America are in general agreement with many studies.

To evaluate the association between learned helplessness (LH) and self-efficacy (SE) with disease activity, functional capacity, and level of pain in patients with rheumatoid arthritis (RA) and to compare LH and SE between patients in remission and patients with active disease.This multicentre, cross-sectional study included consecutive patients (aged ≥ 18 years) with RA according to 2010 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria. LH was measured by the Rheumatology Attitude Index (RAI), Spanish version; SE with the Arthritis Self-efficacy Scale (ASES), Spanish version; functional capacity with the Health Assessment Questionnaire, Argentinian version (HAQ-A); and perceived pain by the visual analogue scale (VAS). Disease activity was measured by the Clinical Disease Activity Index (CDAI).A total of 115 patients (82% females) with a mean (± sd) age of 58 ± 13 years were included. We found a significantly positive correlation between LH and perceived pain (p 0.001), HAQ-A score (p 0.001), and CDAI (p 0.001) and a significantly negative correlation between SE and perceived pain (p 0.001), HAQ-A score (p 0.001), and CDAI (p 0.001). We found greater levels of SE and lower grades of LH in patients in remission compared to those with active disease (median 76 vs. 58; p 0.001 and 6 vs. 11; p 0.001, respectively).LH and SE correlated significantly with disease activity, functional capacity, and perceived pain. Levels of SE were higher in patients in remission compared to those with active disease as opposed to levels of LH, which were lower in patients in remission compared to those with active disease. These results show that cognitive factors are related to disease activity and their modifications may have importance in the management of RA.

Objective. A patient self-administered questionnaire [PsA Screening and Evaluation (PASE)] has been developed and validated in English, but has not been tried in Spanish speaking populations. This study aimed to adapt and validate PASE in Spanish to screen Spanish speaking psoriasis patients for signs and symptoms of inflammatory arthritis. Methods. Initial translation from English to Spanish (forward translation) was performed by two independent translators and the resulting versions were synthesized during a consensus meeting. The questionnaire was tried in a pilot study and resulted in a change in the agreement scale for a frequency scale with wording adaptation [Spanish PASE (PASE-S)]. Results. One hundred and eleven patients were screened with PASE-S; 25 with PsA (without previous treatments), 23 with psoriasis, 22 with psoriasis and OA and 41 with OA without psoriasis. The diagnosis of psoriasis was performed by a dermatologist, and a rheumatologist determined the diagnosis of PsA or OA. Patients with PsA had statistically significant higher symptoms, function and total PASE-S scores compared with those without PsA. Receiver operator curves showed an area under the curve of 0.79 (95% CI 0.69, 0.89) for the total score. A cut-off value 534 showed sensitivity of 76%, and specificity of 74.4% for the diagnosis of PsA. Conclusion. The validated PASE questionnaire is a self-administered tool that can be used to screen for PsA among patients with psoriasis in a Spanish speaking population. PASE was able to distinguish between symptoms of PsA and OA.
