ABSTRACT
BACKGROUND: Intraperitoneal(IP) vancomycin has been widely used for the treatment of peritonitis or exit-site infection associated with continuous ambulatory peritoneal dialysis(CAPD). However, some previous reports in the literature have suggested that IP administration of certain vancomycin may be associated with chemical peritonitis in CAPD patients. METHODS: Between 1 February 1994 and 1 February 1997, 35 consecutive CAPD patients requiring treatment with intraperitoneal vancomycin for either exit-site infection or peritonitis in the Yeungnam University Hospital were recruited retrospectively into the study. We compared retrospectively the incidence of chemical peritonitis after using two different preparations of vancomycin from different pharmaceutical companies, namely vancocin CP(R) and vancomycin(R). RESULTS: Thirty-three cases(all 26 cases given vancocin CP(R) and 7 out of the 9 cases given vancomycin(R)) showed improvement. None of them developed fever, abdominal pain or cloudy dialysate. Out of the 9 cases given IP vancomycin(R), two who currently did not have abdominal pain and cloudy dialysis effluent develolped these symptom and sign at 5 and 6 hours after administration of IP vancomycin. The chemical peritonitis may be secondary to prolonged contact of the peritoneal membrane with one or more of the impurities present in vancomycin preparation. CONCLUSION: In summary, it is necessary for the nephrologists to be aware of the possible chemical peritonitis which can be caused by the impurities of certain brand of vancomycin.
