Objective. To determine the influence of socioeconomic factors on disease activity in a Latin American (LA) early rheumatoid arthritis (RA) multinational inception cohort at baseline. Methods. Clinical evaluation, ethnicity, socioeconomic status (SES), 4-variable Disease Activity Score in 28 joints using the erythrocyte sedimentation rate (DAS28-ESR), Health Assessment Questionnaire (HAQ) disability index (DI), and erosions were recorded in 1,093 patients with early RA (<1 year from onset). Multivariate analyses evaluated influences of sex, age, marital status, education, medical coverage, SES, and ethnicity on HAQ DI, DAS28-ESR, and presence of erosions. Results. Ethnicities included 43% Mestizo, 31% Caucasian, 19% African LA, 4% Amerindian, and 3% other. Fifty-eight percent were of low/low-middle SES, 42% had <8 years of education, 21% had no medical coverage, median disease duration was 6 months (25th, 75th percentiles 4, 9 months), median HAQ DI score was 1.25 (25th, 75th percentiles 0.63, 2.00), median DAS28-ESR score was 6.2 (25th, 75th percentiles 4.9, 7.2), and 25% had erosions. Women and Mestizos, African LA, and Amerindians had earlier onset than men or Caucasians (P < 0.01). When adjusted by country, the analysis of covariance model showed that low/low-middle SES, female sex, partial coverage, and older age were associated with worse HAQ DI scores; only low/low-middle SES was associated with higher DAS28 scores. Statistically significant differences were found in HAQ DI and DAS28 scores between countries. When excluding country, low/lowmiddle SES, female sex, and no coverage were associated with worse HAQ DI and DAS28 scores, whereas separated/ divorced/widowed status was associated with worse HAQ DI scores and age was associated with worse DAS28 scores. Logistic regression showed that older age, no coverage, and the Amerindian and other ethnic groups were associated with erosions. Conclusion. We compared early RA patients from the main LA ethnic groups. Our findings suggest that low/low-middle SES is important in determining disease activity. A more genetic-related background for erosions is possible.

Fibromyalgia (FM) is a syndrome that can be associated with several rheumatic diseases. However, no study has evaluated its frequency in patients with primary antiphospholipid syndrome (PAPS). The objective of this study was to analyze the frequency of FM in PAPS patients compared with healthy controls, to determine the possible associations between FM and PAPS features, and also to evaluate quality of life and depression in these patients. This case-control study included 30 PAPS patients (by the Sapporo criteria) and 40 healthy subjects. Demographic and clinical data, drug use, and antiphospholipid antibodies were analyzed. FM was diagnosed based on international criteria (ACR). Questionnaires on quality of life, including the Short Form 36 Health Survey (SF-36), Beck Depression Inventory (BDI), Fibromyalgia Impact Questionnaire (FIQ), and Visual Analog Scale (VAS), were also applied. PAPS patients and controls were similar in mean age as well as in distributions of gender and Caucasian race. Mean disease duration was 5.4 ± 4.2 years. A diagnosis of fibromyalgia was made in five (16.7%) PAPS patients and no controls (p = 0.012). PAPS patients had more diffuse pain (53% vs. 0%, respectively, p < 0.0001), ≥11 tender points (23% vs. 5%, respectively, p = 0.032), and a greater total number (175 vs. 57, respectively, p < 0.0001) as well as median number of tender points per patient than controls (5 [0-18] vs. 0 [0-11], respectively, p< 0.0001). PAPS patients had lower values in all dimensions of the SF-36, as well as higher FIQ scores, higher BDI scores, more depression diagnoses according to BDI results, and increased VAS in comparison with controls. Analysis of PAPS patients with FM compared with those subjects without FM revealed no significant differences regarding demographic features or thrombotic or clinical events; however, PAPS patients who also had FM had lower values in SF-36 dimensions as well as higher FIQ (82.6 ± 9.6 vs. 33.6 ± 29.8, respectively, p < 0.0001) and VAS scores (6.6 ± 2.97 vs. 3.25 ± 3.11, respectively, p = 0.03). BDI scores, in contrast, were similar in both groups. In conclusion, one-fifth of PAPS patients had fibromyalgia and a low quality of life when compared with healthy subjects.

Background Concerns have been raised that the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, or more severe or critical coronavirus disease (COVID-19), may be higher in immunocompromised individuals receiving immunomodulatory therapies, compared with immunocompetent individuals. Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA), psoriatic arthritis (PsA), ulcerative colitis (UC), and polyarticular course juvenile idiopathic arthritis. To date, data on tofacitinib treatment during the COVID-19 pandemic are limited. Objectives To summarize current understanding of the use of tofacitinib in adults during the COVID-19 pandemic, and discuss research questions that are yet to be addressed, in order to further inform the safe and effective use of tofacitinib in clinical practice. Methods We conducted a review of the literature (as of February 2021), in order to summarize the expert recommendations for the management of RA, PsA, and UC in the context of COVID-19, and to assess the current data regarding the use of tofacitinib in adult patients during the pandemic. Results Current recommendations for RA, PsA, and UC state that tofacitinib treatment should be continued during the pandemic, except in cases of positive or presumed SARS-CoV-2 infection. However, limited data are available; analyses of data from international rheumatology and gastroenterology registries have suggested that tofacitinib may not be associated with an increased risk of hospitalization or treatment switching in adults with COVID-19. Conclusions Further assessment of tofacitinib use in patients with RA, PsA, or UC will be required to elucidate and establish the benefit:risk profile of tofacitinib during the current COVID-19 pandemic.
