The effect of extra-articular manifestations on tumor necrosis factor-α inhibitor treatment duration in patients with ankylosing spondylitis: nationwide data from the Korean College of Rheumatology BIOlogics (KOBIO) registry.

Tumor necrosis factor-α inhibitor (TNFi) therapy has shown to be remarkably effective for treating ankylosing spondylitis (AS); however, nearly 30% of AS patients every year either stop TNFi therapy or switch to a different TNFi due to inefficacy or adverse effects. The goal of this study was to identify predictors of TNFi treatment duration, including extra-articular manifestations, using a nationwide registry in Korea. Data obtained from the Korean College of Rheumatology Biologics (KOBIO) registry, a nationwide, multi-center database representing 58 tertiary care hospitals in Korea.

Cardiac arrest caused by nafamostat mesilate.

A 65-year-old man was transferred from the Department of Vascular Surgery to Nephrology because of cardiac arrest during hemodialysis. He underwent incision and drainage for treatment of a buttock abscess. Nafamostat mesilate was used as an anticoagulant for hemodialysis to address bleeding from the incision and drainage site.

Genetic analysis of ABCG2 and SLC2A9 gene polymorphisms in gouty arthritis in a Korean population.

Background/aims: Gout is a common inf lammatory arthritis triggered by the crystallization of uric acid in the joints. Serum uric acid levels are highly heritable, suggesting a strong genetic component. Independent studies to confirm the genetic associations with gout in various ethnic populations are warranted.
