Mandatory Biological/Targeted Synthetic Disease-Modifying Antirheumatic Drugs Dose Reduction on Risk of Serious Infections in Patients with Rheumatoid Arthritis: A Nationwide Nested Case-Control Study.

ABSTRACT: Background: We aimed to investigate the risk for a serious infection in rheumatoid arthritis (RA) patients after tapering the dose of biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Methods: This nested case-control study investigated the risk for a serious infection in RA patients who underwent mandatory b/tsDMARDs dose reduction 2.5 years after starting therapy with a single b/tsDMARD in the National Health Insurance Research Database (NHIRD). Cases were those patients who developed a serious infection afterwards. Matched controls were selected from those patients who did not develop a serious infection. We used unconditional logistic regression to analyze the odds ratios (ORs) of b/tsDMARDs dose reduction and discontinuation between cases
