Abstract
The peritonitis caused by gram-negative organisms is a serious complication encountered in patients undergoing peritoneal dialysis, often causing high morbidity and mortality. There has been recognition of peritonitis caused by uncommon organisms because of improved microbiological detection techniques. The healthcare providers involved in the management of these patients should be very vigilant. We report a rare case of peritonitis caused bycA 42-year-old male on peritoneal dialysis for five years presented with abdominal pain and cloudy effluent. The peritoneal fluid analysis was consistent with peritonitis, and peritoneal fluid culture grew Citrobacter freundii. The patient was treated with two courses of double antibiotic coverage with intraperitoneal ceftazidime and oral ciprofloxacin, which failed to resolve the infection and hence resulted in the removal the peritoneal dialysis catheter and dialysis modality change.
