Abstract Introduction: Continuous infusion (CI) of high-dose vancomycin is often used to treat life-threatening infections caused by less-susceptible Gram-positive bacteria. However, this approach has not been well studied in patients on continuous renal replacement therapy (CRRT). The aim of this study was to evaluate the adequacy of a new CI vancomycin regimen in septic patients undergoing CRRT. Methods: In this prospective study we measured vancomycin concentrations obtained with a new CI regimen for CRRT, which included a loading dose of 35 mg/kg given over a 4 h period followed by a daily dose of 14 mg/kg. Vancomycin concentrations were measured: at the end of the loading dose (T1); 12 h after the onset of therapy (T2); and 24 h after the onset of therapy (T3). Drug concentrations (at T2 and T3) were considered adequate if between 20 and 30 mg/L. CRRT intensity was calculated as: dialysate rate (mL/kg/h)+ultrafiltration rate (mL/kg/h). Vancomycin population pharmacokinetics were calculated using non-linear mixed-effects modelling. Results: We studied 32 patients who received median (IQR) loading and daily vancomycin doses of 2750 mg (2250-3150) and 1100 mg (975-1270), respectively. Drug concentrations were: T1, 44 mg/L (38-58); T2, 27 mg/L (24-31); and T3, 23 mg/L (19-31). Vancomycin concentrations were adequate in 22/32 patients (69%) at T2 and in 20/32 (63%) at T3. The two relevant covariates that significantly affected drug concentrations were body weight and CRRT intensity. Conclusions: This new vancomycin regimen allowed the rapid achievement of target drug concentrations in the majority of patients. CRRT intensity had an influence on vancomycin clearance.
