|Peritoneal Dialysis-associated Peritonitis||Drug: Vancomycin||Phase 1|
Peritoneal dialysis (PD) is a form of renal replacement therapy indicated for those with acute kidney injury or end stage renal disease. Currently, two modalities of PD exist and is individualized based on patient and life-style specific factors. Continuous ambulatory peritoneal dialysis (CAPD) allows 4 - 5 exchanges performed manually whereas automated peritoneal dialysis (APD) involves continuous, automated, cyclical exchanges performed by a device at home during the night. Peritonitis is a common complication in PD and accounts for a large portion of hospital readmission and mortality. Vancomycin is the most common antibiotic recommended and has notable gram-positive coverage used empirically during suspected peritonitis.
Despite widespread use, vancomycin lacks good pharmacokinetic characterization in PD. Early pharmacokinetic studies using vancomycin were conducted predominantly in patients on CAPD on glucose-based prescriptions. Data is non-existent in PD patients administered the novel dialysate solution icodextrin, or those treated with overnight APD. The impact of residual kidney function (RKF) on vancomycin in PD is also lacking. Enhanced vancomycin clearance in RKF may result in under-dosing, while overdosing may result in nephrotoxicity and loss of clinically important RKF.
The investigators will characterize the pharmacokinetic profile of vancomycin following a single intraperitoneal dose of vancomycin in icodextrin dialysate to non-infected PD patients and examine the relationship between RKF and vancomycin clearance using serum, dialysate and urine. The goal is to use this data in non-infected subjects to generate information to guide vancomycin dosing in patients on rapid-cycling PD modalities.
