An unusual case of tuberculous peritonitis complicating continuous ambulatory peritoneal dialysis

We describe a case of tuberculous peritonitis with unusual manifestations i n a continuous ambulatory peritoneal dialysis (CAPD) patient. In such patie nts, tuberculous peritonitis typically produces a neutrophil predominance i n dialysate differential counts. In the presented patient, dialysate analys is revealed only lymphocyte predominance. Additionally, his condition impro ved, with no white blood cells found in dialysate samples after empirical c efazolin and gentamycin antimicrobial therapy. Nevertheless, dialysate samp les did yield Mycobacterium tuberculosis during the sixth week of hospitali zation, and a diagnosis of of tuberculous peritonitis was made. This case s hows that tuberculous peritonitis should not be excluded in a CAPD patient, even when showing a satisfactory clinical response to empirical antibiotic s.
