  • Peritonitis is a common and potentially serious infection in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). The most common organisms usually associated with CAPD peritonitis are Staphylococcus aureus and Staphylococcus epidermidis. Rarely, aerobic gram negative bacilli have been the causative agents of CAPD peritonitis. The treatment of CAPD peritonitis requires removal of the peritoneal catheter and treatment with parenteral antibiotics active against the causative pathogen. While hospitalized for CAPD peritonitis, a 55-year-old man on CAPD had nosocomial peritonitis secondary to infection by ESBL–producing E. coli, that was sensitive to imipenem and meropenem. He was treated successfully with a 4-week course of intraperitoneal meropenem therapy without subsequent relapse, loss of peritoneal catheter, ultrafiltration failure, or dialysis inadequacy.
