Bone Status in Patients with Monoclonal Gammopathy of Undetermined Significance: A Case-Control Study.

Objective: The objective of the study was to assess the prevalence of osteoporosis in patients with monoclonal gammopathy of undetermined significance (MGUS) and to determine the associated factors.

Materials And Methods: We conducted a case-control study, between January 2019 and April 2019, including patients with MGUS and age- and sex-matched healthy controls (one patient/three controls). For all participants, demographic and clinical data were collected as results of bone mineral density by two-photon X-ray absorptiometry at the lumbar spine and femoral neck.

Cachexia Prevalence in a Population of Moroccan Women with Rheumatoid Arthritis.

Objective: To assess body composition in women with rheumatoid arthritis (RA) compared to healthy controls, to calculate the prevalence of rheumatoid Cachexia (RC), and to identify the associated factors.

Methods: We conducted a case-control study on 112 female patients with RA according to the 2010 American College of Rheumatology/European League Against Rheumatism classification criteria for RA; and 224 age-matched healthy women. Body composition (BC) and bone mineral density (BMD) scans were obtained using Dual-energy X-ray absorptiometry (DXA).

Extra-Articular Manifestations in Patients with Ankylosing Spondylitis: Baseline Characteristics from the RBSMR Study.

Objectives: To describe and analyse the prevalence of extra-articular manifestations (EAMs) including acute anterior uveitis (AAU), psoriasis and inflammatory bowel disease (IBD) in patients with ankylosing spondylitis (AS) in the Moroccan registry of biological therapies in rheumatic diseases RBSMR (Registre des Biothérapies de la Société Marocaine de Rhumatologie).

Methods: A cross-sectional, multicentre and analytical study based on the RBSMR database, which included 170 AS. Incidence rates for the development of AAU, psoriasis and IBD were calculated, and risk factors were analysed.

Discontinuation of biologic therapy in patients with rheumatoid arthritis and ankylosing spondylitis: analysis from multicenter cohort study.

Despite of the availability of several effective bDMARDs, a significant proportion of rheumatoid arthritis (RA) and ankylosing spondylitis (AS) patients discontinued bDMARDs. The aims of this study were to analyze causes of bDMARDs discontinuation in RA and AS included in the Moroccan registry RBSMR. A historical prospective multicenter cohort study based on the RBSMR database at 12 months of follow-up, which included 225 RA and 170 AS.

Reproducibility of total and regional body composition using dual-energy X-ray absorptiometry in rheumatoid arthritis and ankylosing spondylitis.

Unlabelled: Several studies have reported changes in body composition in rheumatoid arthritis (RA) and ankylosing spondylitis (AS). Our study showed that body composition measurements obtained by absorptiometry were highly reproducible in patients suffering from these diseases. This study justifies the use of absorptiometry measurements in longitudinal studies in this population.
