Clinical Characteristics of Young-Onset Versus Elderly-Onset Rheumatoid Arthritis: A Systematic Review and Meta-Analysis.

Rheumatoid arthritis (RA) is a chronic inflammatory disease with a prevalence of 1%, mainly affecting women aged 25-45. It is classified by the age of onset into young-onset rheumatoid arthritis (YORA, 16-65 years) and elderly-onset rheumatoid arthritis (EORA, over 65 years), with EORA often presenting suddenly with systemic symptoms and large joint involvement due to age-related immune changes. This systematic review and meta-analysis compare the clinical and epidemiological characteristics of EORA and YORA.

Impact of intimate partner violence on quality of life and disease activity in women with systemic lupus erythematosus.

Objective: Stress and trauma are psychosocial factors with an impact on the course of systemic lupus erythematosus (SLE). The influence of violence on SLE has not been entirely explored, even though women (including patients with rheumatic diseases) are a vulnerable population to any form of violence. This study aims to assess the prevalence and impact of intimate partner violence (IPV) on health-related quality of life in women with SLE.

Bone erosions by MRI in first-degree relatives of patients with RA: an exploratory study.

Introduction/objectives: First-degree relatives (FDR) of patients with rheumatoid arthritis (RA) are at increased risk of RA diagnosis. Magnetic resonance imaging (MRI) has been proposed as a useful tool to detect subclinical synovitis and bone abnormalities as predictors of progression to RA. The presence of grade ≥ 2 bone erosions in RA MRI scoring system (RAMRIS) was reported to be RA-specific.

Vaccination in rheumatic disease patients: results of a pilot quality improvement program.

Objectives: Patients with rheumatic diseases (RD) are at increased risk of infections. Vaccination is recognized as a successful public health measure and is recommended for RD patients. The aim of this study was to describe the strategies implemented in an academic rheumatology outpatient clinic as part of a fellow-in-training-led vaccination quality improvement (QI) program and to explore the vaccination uptake before and one year after the implementation.

Comorbidity burden in terms of disability in patients with osteoarthritis in Mexico. The IMPACTAR registry.

Objective: To determine the comorbidities associated with disability in patients with OA in Mexico (2013-2015).

Material And Methods: A cross-sectional, retrospective and multicentre IMPACTAR study (n=7703) in Mexican patients (2013-2015). Comorbidities associated with disability were identified in 4971 patients diagnosed with OA from the IMPACTAR registry (n=7073).

Adverse events of six COVID-19 vaccines in patients with autoimmune rheumatic diseases: a cross-sectional study.

Data regarding COVID-19 vaccine efficacy and adverse events (AE) in patients with autoimmune and inflammatory rheumatic diseases (AIIRD) have been published recently although these mostly include the mRNA vaccines (Pfizer-BioNTech and Moderna) and the ChAdOx1 nCoV-19/AZD1222 (Oxford-AstraZeneca). This research aimed to study the prevalence of AE presented with six different SARS-CoV-2 vaccines {ChadOX1 nCoV-19 (AZD1222), Ad5-nCoV2, Ad26.COV2.

Mycophenolate mofetil and mycophenolic acid for the treatment of eosinophilic fasciitis: report of two cases and literature review.

Eosinophilic fasciitis (EF) is an uncommon autoimmune connective tissue disorder characterized by edema, erythema, and subsequent induration of the extremities. It is commonly treated with corticosteroids but there is no treatment ladder for immunosuppressants or steroid-sparing agents. We report two EF cases treated effectively with mycophenolate mofetil (MMF) or mycophenolic acid (MPA) and present a literature review.

Efficacy and safety of weekly vitamin D in patients with fibromyalgia: 12-week, double-blind, randomized, controlled placebo trial.

Introduction: FM is a chronic musculoskeletal disorder characterized by the presence of generalized pain. There are contradictory results regarding the prevalence and supplementation effect of vitamin D deficiency on FM patients. We aim to determine the safety and efficacy of a 12-week vitamin D supplementation on FM patients.

A longitudinal multiethnic study of biomarkers in systemic lupus erythematosus: Launching the GLADEL 2.0 Study Group.

After more than 20 years of sustained work, the Latin American Group for the Study of Lupus (GLADEL) has made a significant number of contributions to the field of lupus, not only in the differential role that race/ethnicity plays in its course and outcome but also in several other studies including the beneficial effects of using antimalarials in lupus patients and the development of consensus guidelines for the treatment of lupus in our region. A new generation of "Lupus Investigators" in more than 40 centers throughout Latin America has been constituted in order to continue the legacy of the investigators of the original cohort and to launch a novel study of serum and urinary biomarkers in patients with systemic lupus erythematosus. So far, we have recruited 807 patients and 631 controls from 42 Latin-American centers including 339 patients with SLE without renal involvement, 202 patients with SLE with prevalent but inactive renal disease, 176 patients with prevalent and active renal disease and 90 patients with incident lupus nephritis.

Knowledge and attitudes about influenza vaccination in rheumatic diseases patients.
