Features of sarcopenic obesity in rheumatoid arthritis patients.

Aim: The present study aimed to determine the proportion of rheumatoid arthritis (RA) patients with sarcopenic obesity and to identify associated factors through assessments of physical function and patient-reported outcomes (PROs).

Methods: A prospective cohort study of 321 RA patients aged 40-79 years was conducted. Participants were classified into four groups-Normal, Obesity, Sarcopenia, and Sarcopenic obesity-based on sarcopenia criteria, which included skeletal muscle mass index, grip strength, and physical function, as well as obesity criteria defined by body fat percentage.

Methods: This cross-sectional study included 34 patients with AS and 73 patients without AS who underwent spinal CT between 2004 and 2022. HU values were measured from C3 to L5 in patients with AS and from L1 to L5 in patients without AS.

Protocol: Filgotinib in addition to methotrexate versus filgotinib monotherapy in patients with rheumatoid arthritis with an inadequate response to methotrexate: A multicenter, prospective, open-label, randomized controlled trial (FAITHFUL Study).

Background: Filgotinib (FIL), a Janus kinase-1 preferential inhibitor, has been studied for its efficacy and safety in rheumatoid arthritis. The FINCH3 trial compared FIL monotherapy, FIL plus methotrexate (MTX) combination therapy, and MTX monotherapy in MTX-naïve patients. However, comparisons in patients with an inadequate response to MTX remain unclear.

Objective: The present non-inferiority study was designed to compare the effect of discontinuing versus continuing methotrexate (MTX) alongside certolizumab pegol (CZP) on maintaining low disease activity (LDA) in rheumatoid arthritis (RA) patients already stable on combination therapy.

Methods: This multicentre, open-label, randomised, controlled trial included RA patients with sustained LDA (Clinical Disease Activity Index [CDAI] ≤ 10) for ≥ 12 weeks with CZP + MTX. Patients were randomised 1:1 by computer to either continue MTX (CZP + MTX group) or discontinue MTX after a 12-week reduction period (CZP group) using a dynamic allocation strategy with the minimisation method.

Increased sputum peripheral helper T cells are associated with the severity of rheumatoid arthritis but not with the severity of airway disease.

Objective: Peripheral helper T (Tph) cells, together with plasma cells, are the major pathogenic lymphocytes in the synovium in rheumatoid arthritis (RA). However, whether these cells are involved in RA-associated lung and/or airway disease is unknown.

Methods: Tph cells in sputum were analyzed by flow cytometry and compared with those in synovial fluid and synovial tissue.

Association of spinal ankylosis with spinal mobility and functional impairment in radiographic axial spondyloarthritis: A computed tomography study.

Objective: This study aimed to examine relationships of the degree and level of spinal ankylosis with spinal mobility and functional impairment in patients with radiographic axial spondyloarthritis (r-axSpA) using computed tomography (CT).

Methods: This retrospective study involving 27 patients examined the number of fused intervertebral segments in the whole, cervical, thoracic, and lumbar spine using CT as a measure of spinal ankylosis, Bath Ankylosing Spondylitis Metrology Index (BASMI) as a measure of spinal mobility, and Bath Ankylosing Spondylitis Functional Index (BASFI) as a measure of functional impairment.

Results: Significant positive correlations were found between both BASMI and BASFI and the number of fused intervertebral segments in the whole, cervical, thoracic, and lumbar spine.
