Abstract
Abstract Background Continuous ambulatory peritoneal dialysis is a cost effective and efficient modality of renal replacement therapy. However, infectious processes such as peritonitis may lead to peritoneal membrane failure necessitating shift to hemodialysis. Tuberculous peritonitis is an unusual cause of peritonitis, which may lead to risk of hospitalization and significant morbidity and mortality. Aims To determine the prevalence and outcomes of tuberculous peritonitis among patients on continuous ambulatory peritoneal dialysis Method A retrospective, descriptive study of patients on continuous ambulatory peritoneal dialysis with tuberculous peritonitis from January 2016 to January 2023 in National Kidney and Transplant Institute. Demographic, clinical and laboratory data of patients with TB peritonitis were collected via chart review. Results Among 1182 patients on continuous ambulatory peritoneal dialysis, 2.03% had tuberculous peritonitis. Average length of time from development of symptoms to diagnosis is 24.5 days. Majority of presenting symptoms were hazy drain and abdominal pain. 66.7% retained their peritoneal dialysis catheter. PD catheter was removed in 33% of TB peritonitis due to peritoneal dialysis failure and unresolving peritonitis. Mortality was 37.5% after diagnosis of tuberculous peritonitis. Only significant factor associated with mortality was length of time on continuous ambulatory peritoneal dialysis to development of TB peritonitis (p = 0.0332). Conclusion Relative high prevalence of tuberculous peritonitis could be related to high background occurrence of tuberculosis in the country. Majority of cases had resolution of symptoms and effective dialysis during course of anti-tuberculous treatment and did not warrant peritoneal dialysis catheter removal.
