A 49-year-old man was admitted with peritonitis nine months after starting continuous ambulatory peritoneal dialysis (CAPD) for kidney failure. Ceftazidime and cefazolin were started. Peritoneal dialysate culture was negative for bacteria, but antibiotic treatment was continued because peritonitis improved. Twenty days later, the patient was discharged with no signs of peritonitis. However, 40-day culture of the original peritoneal dialysate detected Mycobacterium tuberculosis, and peritonitis recurred, leading to readmission. A T-SPOT test was performed and was positive in 4 days. Anti-tuberculosis therapy was started, which cured the peritonitis. The T-SPOT test may enable early diagnosis of tuberculosis.
