Tuberculous Peritonitis in a Patient with Rheumatoid Arthritis Treated with Infliximab

One of the severe adverse reactions to anti-tumor necrosis factor (TNF)-α therapy is the reactivation of tuberculosis. We present a case of tuberculous peritonitis in a 57-yearold woman with rheumatoid arthritis (RA) that appeared during treatment with infliximab. Confirming a diagnosis of tuberculous peritonitis is difficult and can be delayed because of the nonspecific symptoms, the rarity of the disease, and the low detection rate of mycobacteria in ascites fluid. This case illustrates that prompt anti-tuberculous therapy is needed for suspected cases of tuberculous peritonitis in RA patients treated with infliximab.
