Background Various observations have suggested that the course of COVID-19 might be less favourable in patients with inflammatory rheumatic and musculoskeletal diseases receiving rituximab compared with those not receiving rituximab. We aimed to investigate whether treatment with rituximab is associated with severe COVID-19 outcomes in patients with inflammatory rheumatic and musculoskeletal diseases.Methods In this cohort study, we analysed data from the French RMD COVID-19 cohort, which included patients aged 18 years or older with inflammatory rheumatic and musculoskeletal diseases and highly suspected or confirmed COVID-19. The primary endpoint was the severity of COVID-19 in patients treated with rituximab (rituximab group) compared with patients who did not receive rituximab (no rituximab group). Severe disease was defined as that requiring admission to an intensive care unit or leading to death. Secondary objectives were to analyse deaths and duration of hospital stay. The inverse probability of treatment weighting propensity score method was used to adjust for potential confounding factors (age, sex, arterial hypertension, diabetes, smoking status, body-mass index, interstitial lung disease, cardiovascular diseases, cancer, corticosteroid use, chronic renal failure, and the underlying disease [rheumatoid arthritis vs others]). Odds ratios and hazard ratios and their 95% CIs were calculated as effect size, by dividing the two population mean differences by their SD. This study is registered with ClinicalTrials.gov, NCT04353609.

BackgroundPersistent symptoms, mainly joint and muscular pain and depression, have been reported several months after Chikungunya virus (CHIKV) infection. Their frequency and their impact on quality of life have not been compared with those of an unexposed population. In the present study, we aimed to describe the frequency of prolonged clinical manifestations of CHIKV infection and to measure the impact on quality of life and health care consumption in comparison with that of an unexposed population, more than one year after infection.Methodology/Principal FindingsIn a retrospective cohort study, 199 subjects who had serologically confirmed CHIKV infection (CHIK+) were compared with 199 sero-negative subjects (CHIK–) matched for age, gender and area of residence in La Réunion Island. Following an average time of 17 months from the acute phase of infection, participants were interviewed by telephone about current symptoms, medical consumption during the last 12 months and quality of life assessed by the 12-items Short-Form Health Survey (SF-12) scale. At the time of study, 112 (56%) CHIK+ persons reported they were fully recovered. CHIK+ complained more frequently than CHIK– of arthralgia (relative risk = 1.9; 95% confidence interval: 1.6–2.2), myalgia (1.9; 1.5–2.3), fatigue (2.3; 1.8–3), depression (2.5; 1.5–4.1) and hair loss (3.8; 1.9–7.6). There was no significant difference between CHIK+ and CHIK– subjects regarding medical consumption in the past year. The mean (SD) score of the SF-12 Physical Component Summary was 46.4 (10.8) in CHIK+ versus 49.1 (9.3) in CHIK– (p = 0.04). There was no significant difference between the two groups for the Mental Component Summary.Conclusions/SignificanceMore than one year following the acute phase of infection, CHIK+ subjects reported more disabilities than those who were CHIK–. These persistent disabilities, however, have no significant influence on medical consumption, and the impact on quality of life is moderate.

J Clin Hypertens (Greenwich). 2012; 14:429–434. © 2012 Wiley Periodicals, Inc. The aim of this study was to validate a French translation of the structured self‐report 8‐item Morisky Medication Adherence Scale (MMAS‐8) and determine its psychometric properties in patients taking antihypertensive medication. An observational cross‐sectional study was conducted in the hypertensive unit of a French university hospital. The MMAS‐8 was translated according to international guidelines. Internal consistency was assessed using Cronbach α coefficient, construct validity using principal component and confirmatory factor analyses, and the test‐retest reliability at 1‐month interval using the intraclass correlation coefficient (ICC). Three levels of adherence were considered (low: scores of 0 to <6; medium: 6 to <8; high: 8) and risk factors were explored in ordinal logistic regression models. A total of 199 patients were included: mean age, 55.7±14.6 years, 57.3% men (114 of 199), and 39.5% (66 of 167) had uncontrolled blood pressure. The French MMAS was moderately reliable (α=0.54), one‐dimensional, and reproducible (ICC=0.68). The mean score was 6.96 (standard deviation 1.25) and 17.6% (35 of 199), 37.7% (75 of 199), and 43.7% (87 of 199) of patients had low, medium, and high adherence, respectively. The only factor significantly associated with adherence was age. The French MMAS has acceptable psychometric effects to measure medication adherence in hypertensive patients and may be useful in detecting nonadherent hypertensive patients.
