Construct validity, reliability, response rate, and association with disease activity of the quick disabilities of the arm, shoulder and hand questionnaire in the assessment of rheumatoid arthritis.
First objective is to validate the Disabilities of the Arm, Shoulder and Hand (DASH) and Quick DASH (QuickDASH) questionnaire in rheumatoid arthritis (RA) patients with functional upper extremity impairment. Next is to clarify which clinical factor is associating with QuickDASH using a large cohort of RA. ⋯ QuickDASH seems suitable for evaluating upper extremity impairment, disability index, and disease control in a large cohort of RA patients including elderly patients.

Drug retention rates of second biologic agents after switching from tumor necrosis factor inhibitors for rheumatoid arthritis in Japanese patients on low-dose methotrexate or without methotrexate.
The purpose of this study was to explore drug retention rates of second biologic agents after switching from tumor necrosis factor inhibitors (TNFi) in clinical practice in patients with rheumatoid arthritis (RA) on low-dose methotrexate (MTX) or without MTX. ⋯ Drug retention rates of IFX and ADA after switching from the first TNFi were significantly lower compared to those of ETN and TCZ in patients on low-dose MTX or without MTX.

Clinicopathologic characteristics of IgG4-related retroperitoneal fibrosis among patients initially diagnosed as having idiopathic retroperitoneal fibrosis.
Abstract Objective. The purpose of our study was to determine the number of IgG4-related retroperitoneal fibrosis (RPF) cases that were initially diagnosed as idiopathic RPF and to investigate clinical characteristics of IgG4-related RPF. Methods. ⋯ Conclusions. We found that 47% of the patients initially diagnosed with idiopathic RPF showed IgG4-related RPF evidence according to the pathology and IgG4-related RPF patients showed higher recurrence rate than idiopathic RPF patients. We suggest that maintenance immunosuppressive therapy is required in IgG4-related RPF patients.
