Peritoneal clearance and total body elimination of vancomycin during chronic intermittent peritoneal dialysis.

Abstract

Vancomycin is a useful antimicrobial agent in patients undergoing chronic hemodialysis treatment; its efficacy in chronic peritoneal dialysis (CPD) has not been established. Serum (VS) and peritoneal fluid (VPF) vancomycin concentrations were measured in two CPD patients with staphylococcal peritonitis. Half-life of VS agreed with the half-life of VPF in each patient, and the VS/VPF ratio was 1.27 in both patients. Distribution volumes were 37.2 and 58.7 l, values approximating total body water in these patients. VS and VPF persisted in the therapeutic range (greater than 5 microgram/ml) for more than 16 days. In one patient, mean peritoneal clearacne was 9.8 ml/min, and overall drug clearance averaged 2.3 ml/min; in the other patient, overall clearance was 2.1 ml/min. These results indicate that therapeutic vancomycin levels can be maintained for more than 16 days with a single 1 g intravenous dose in patients receiving intermittent CPD, as is the case for hemodialysis patients. Because of this, parenteral vancomycin is useful in the treatment of staphylococcal peritonitis in CPD patients.
