A case of high tibial osteotomy in a patient with psoriatic arthritis.

Traditionally, patients with rheumatic diseases, such as rheumatoid arthritis (RA), were considered off-limits for joint-sparing surgery. In the present study, we report bilateral knee joints of psoriatic arthritis coexisting with osteoarthritis, with good, albeit short-term, results. 62-year-old woman was treated for psoriatic arthritis with a biologic (adalimumab).

Cluster analysis identifies the differential impact of disease activity and severity on functional status and patient satisfaction in rheumatoid arthritis: the FRANK registry.

Objectives: The purpose of the present study was to investigate the differential impact of disease activity and severity on functional status and patient satisfaction in rheumatoid arthritis (RA) using cluster analysis on data from the FRANK registry.

Methods: Data from 3,619 RA patients in the FRANK registry were analysed. Patients were grouped using hierarchical and k-means cluster analyses based on age, physician's global assessment (PhGA), patient's pain assessment (PtPA), and Steinbrocker stage.

Efficacy and safety of baricitinib in rheumatoid arthritis patients with moderate renal impairment: a multicenter propensity score matching study.

Background: This study aimed to compare the efficacy and safety of baricitinib in patients with rheumatoid arthritis (RA) receiving different doses based on renal function.

Methods: We conducted a retrospective study within the JAK Study Group, involving 23 facilities in Fukuoka Prefecture, examining patients treated with baricitinib for RA. Patients were categorized into two dose groups: 4 mg with normal/mild renal dysfunction and 2 mg with moderate renal dysfunction.

Bilateral Snapping Knee in a Patient with Rheumatoid Arthritis Accompanied by Sjögren's Syndrome - A Case Report.

Introduction: We experienced a rare case in which a bilateral snapping knee was caused by rheumatoid arthritis accompanied by Sjögren's syndrome (SS), and the symptoms were resolved by arthroscopic surgery.

Case Report: A 43-year-old Asian male presented at another hospital with finger, shoulder, and knee pain and was diagnosed with rheumatoid arthritis accompanied by SS. Two months later, he developed the snapping phenomenon in both knees and presented at our hospital.

Usefulness of Sarilumab in Patients with Rheumatoid Arthritis after Regression of Lymphoproliferative Disorders.

Lymphoproliferative disorders (LPDs) are serious complications associated with rheumatoid arthritis (RA) treatment that mostly occur during methotrexate (MTX) treatment. Cessation of MTX may induce regression of LPDs but is often followed by a flare of RA. Here, we describe two patients with RA flares after the discontinuation of MTX due to LPDs and sarilumab was useful for the treatment of RA without a relapse of LPDs.
