title: Tuberculous peritonitis complicating long-term peritoneal dialysis. Report of 5 cases and review of the literature.
abstract: The characteristics of 5 patients who developed tuberculous peritonitis while receiving long-term peritoneal dialysis (PD) are presented. There were 2 males and 3 females. 3 patients were on intermittent and 2 were on continuous ambulatory peritoneal dialysis when tuberculous peritonitis was first diagnosed. None of the patients had recently received immunosuppression therapy or were diabetics. The clinical presentations were similar to other forms of peritonitis complicating PD except for a more insidious onset. As extraperitoneal involvement and peritoneal lymphocytosis were rarely present, the diagnosis was mainly dependent on the direct demonstration of Mycobacterium tuberculosis with smear (1 patient) and culture (4 patients). In 1 patient with a pleuroperitoneal communication, the diagnosis was made by pleural biopsy and a positive response to antituberculous therapy. All patients responded to treatment with a combination of three antituberculous drugs which included streptomycin, isoniazid, rifampicin and pyrazinamide. Two patients were transferred to hemodialysis. In 3 patients, peritoneal dialysis was continued. Peritoneal clearance and ultrafiltration capacity were unchanged for up to 16 months after treatment in 2 patients who continued peritoneal dialysis but was reduced by 30 and 50%, respectively, in the remaining patient. Only 1 patient died, but her death was not directly related to tuberculous peritonitis. It was concluded that with a high index of suspicion and early institution of treatment, tuberculous peritonitis complicating PD can be successfully treated with low mortality and without compromising the dialysis capacity of the peritoneal membrane.
