Abstract

Peritonitis is one of the most serious complications of continuous ambulatory peritoneal dialysis (CAPD). Approximately 20% of peritonitis infections have been reported to be resistant to initial therapy, either failing to resolve with appropriate antibiotics or relapsing within 2 weeks of antibiotic discontinuation. To investigate the current situation with regard to resistant peritonitis, we retrospectively examined the incidence and the organisms of resistant peritonitis in our unit over a period of 9 years. From January 1, 1994, to January 1, 2003, we introduced 325 patients onto CAPD. At January 1, 2003, we followed up 172 patients who were receiving CAPD in our unit. During 1994-1996, 12 cases of peritonitis and 3 cases of resistant peritonitis (25%) occurred among our patients. Microbiologic examination revealed that the organisms involved in peritonitis were alpha-streptococcus (17%), coagulase-negative staphylococcus [CNS (17%)], and methicillin-sensitive Staphylococcus aureus [MSSA (17%)]. The organisms of resistant peritonitis were methicillin-resistant S. aureus [MRSA (67%)] and methicillin-resistant CNS (33%). During 1997-1999, 39 cases of peritonitis and 13 cases of resistant peritonitis (33%) occurred among our p...Continue Reading
