Tuberculous peritonitis in a cohort of continuous ambulatory peritoneal dialysis patients.
Among 155 patients who were initiated on continuous ambulatory peritoneal dialysis (CAPD), 4 patients (2 men, 2 women) developed tuberculous peritonitis. They had been on PD for between 2 months and 84 months when they developed the peritonitis. The Mantoux test was negative in all of them. The diagnosis was made by a variety of means in the various cases: demonstration of Mycobacterium tuberculosis in the peritoneal cavity; presence of caseating granuloma in a peritoneal biopsy; Mycobacterium tuberculosis in a cold abscess adjacent to the peritoneal cavity; and demonstration of IS6110 and MPB64 genes of Mycobacterium tuberculosis by polymerase chain reaction (PCR) technique. Two of the patients developed ultrafiltration failure. Among 3 patients who were switched to hemodialysis, 2 died and 1 continues on maintenance dialysis. The last patient, whose catheter was removed, was reimplanted with a new catheter and continues on PD without ultrafiltration failure. Any patient with peritonitis unresponsive to conventional therapy should be investigated for tuberculous peritonitis. Institution of chemotherapy without delay will preserve peritoneal membrane integrity.
