摘要:

目的: 分析腹膜透析相关性腹膜炎(peritoneal dialysis-related peritonitis,PDRP)患者腹腔内注射万古霉素后血药浓度的影响因素及与临床疗效的相关性。方法: 回顾性收集2021年1月至2024年8月苏州大学附属第一医院37例接受腹腔1 g万古霉素给药并监测血药浓度的PDRP患者临床资料,于第2次给药前0.5 h采血,测定首次血药浓度(谷浓度)。结果: 17例既往有腹膜炎感染史的PDRP患者首次血药浓度为11.22(9.46,11.93)μg/mL,显著高于20例无感染史的PDRP患者首次血药浓度[8.66(7.84,9.51)μg/mL(P<0.01)];Logistic回归分析提示腹膜炎感染史及给药间隔时长是首次血药浓度的独立影响因素(P<0.01);腹膜炎感染史在任何给药间隔下均能提高浓度,而给药间隔时间仅在无感染史患者中起明显作用;万古霉素治疗前、后,腹透液细胞成分及转阴天数在高浓度组与低浓度组差异无统计学意义(P>0.05);两组治疗后腹透液细胞成分和C反应蛋白(C-reactive protein,CRP)水平均较治疗前下降(P<0.05);高浓度组患者治疗后CRP水平较低浓度组患者高(P<0.05)。结论: 既往腹膜炎感染史和给药间隔时长可显著影响万古霉素首次血药浓度,但首次浓度水平对PDRP患者的临床疗效和转阴天数无显著影响。

Abstract:

AIM: To investigate the factors influencing the first serum concentration of vancomycin and its relationship to clinical efficacy in patients with peritoneal dialysis-related peritonitis (PDRP) receiving intraperitoneal administration. METHODS: We collected clinical data from 37 PDRP patients treated at The First Affiliated Hospital Of Soochow University between January 2021 and August 2024. All patients received 1 g intraperitoneal vancomycin and underwent serum concentration monitoring. Blood samples were drawn 0.5 h before the second dose to determine the first serum concentration. RESULTS: Seventeen patients with a prior history of peritonitis had a significantly higher first serum concentration [11.22(9.46,11.93) μg/mL] than 20 patients without such history [8.66(7.84,9.51) μg/mL; P<0.01]. Logistic regression identified that both prior peritonitis history and dosing interval duration were independent factors affecting the first serum concentration (P<0.01). A history of peritonitis elevates the first serum concentration at any dosing interval, whereas dosing interval significantly impacts concentrations only in patients without such a history. Before and after vancomycin treatment, there was no significant difference between the high-concentration group and the low-concentration group in the cell components of peritoneal fluid or time to negative culture conversion (P>0.05). Both groups showed significant reductions in the cell components of peritoneal fluid and C-reactive protein (CRP) levels post-treatment compared to baseline (P<0.05). Post-treatment CRP levels were significantly lower in the low-concentration group than in the high-concentration group (P<0.05). CONCLUSION: A history of prior peritonitis and the length of the dosing interval significantly affect the first serum concentration of intraperitoneal vancomycin in PDRP patients; However, the absolute first serum concentration level does not appear to influence clinical efficacy or time to culture negativity.
