Abstract:
OBJECTIVE：To study the effects of augmented renal clearance （ARC）on blood trough concentration of patients receiving high-dose regimen of teicoplanin. METHODS ：Patients who received high-dose regimen of teicoplanin in the ICU were prospectively collected from the Affiliated Suzhou Hospital of Nanjing Medical University/Suzhou Municipal Hospital during Jul. 2018-Jun. 2020. They were divided into ARC group and normal renal function group according to corrected creatinine clearance. The dosage regimen of teicoplanin in the two groups were loading dose of 600 mg，q12 h×3 doses，maintenance dose of 6-10 mg/kg，qd，and the dosage was adjusted in combination with creatinine clearance rate and blood trough concentration. The trough concentration of blood samples which were collected 30 min before the 4th and 8th-10th dosage of teicoplanin were determined by HPLC. Trough concentration ，clinical efficacy ，Gram-positive bacterial clearance rate and the occurrence of ADR were compared between 2 groups. RESULTS ：A total of 56 patients were included and divided into ARC group （18 cases）and normal renal function group （38 cases）. ARC group had younger age （P＜0.001）and lower serum albumin level （P＝0.025）than normal renal function group. The trough concentrations before administration of the 4th and 8th-10th dosage in ARC group were lower than normal renal function group （P＝0.034；P＝0.035）. The trough concentrations in the ARC group and normal renal function group before 8th-10th dosage were all higher than 30 min before the 4th dosage （P＝0.003；P＜0.001）. The clinical efficacy rate and the clearance rate of Gram-positive bacteria in ARC group were 77.8％ and 76.2％，which were lower than those of the normal renal function group ，but there was no statistical difference （P＝0.195；P＝0.223）. There was no liver function damage ，hemocytopenia and allergic reaction in both groups ，but in the normal renal function group ，the causal relationship between acute renal damage and teicoplanin was assessed as “very likely ”in one patient. CONCLUSIONS ：ARC patients are younger ，most of them have hypoproteinemia，and the blood trough concentrations of teicoplanin in high-dose regimen are significantly lower than those of normal renal function patients. For critical ill ARC patients ，it is advisable to increase the loading dose of teicoplanin to make the trough concentration reach the target concentration range quickly.
