Biologic therapies increase risk for infection in patients with rheumatoid arthritis (RA). Because tumor necrosis factor (TNF) is involved in development of sepsis, anti-TNF agents and interleukin (IL)-1 receptor antagonists were first studied in patients with sepsis (rather than as anti-RA medications) but showed little efficacy. However, in animal models, treatment with these agents before sepsis development did improve survival. In this observational study from Germany, investigators examined outcomes of serious infections in 12,000 RA patients who were being treated with biologic or conventional disease-modifying antirheumatic drugs (DMARDs).
During follow-up of 5 to 10 years, 1017 serious infections (most commonly pneumonia and bone and…
