摘要
目的 探究慢性肾小球肾炎血液透析患者导管相关性感染影响因素及与血清miRNA-15a、miRNA-21表达.方法 以2021年6月-2023年6月于浙江大学附属邵逸夫医院就诊的97例慢性肾小球肾炎血液透析患者为研究对象,检测导管相关性感染患者病原菌分布,分析血清miRNA-15a、miRNA-21表达对感染的评估价值及慢性肾小球肾炎血液透析出现导管相关感染的影响因素.结果 慢性肾小球肾炎患者导管相关性感染率为19.59％,其中包括血流感染14例、局部感染5例.19例导管相关性感染患者共检出病原菌19株,其中革兰阳性菌检出率最高.感染组血清miRNA-15a水平低于未感染组,miRNA-21水平高于未感染组(P＜0.05).受试者工作特性(ROC)曲线分析显示,血清指标联合检测诊断血液透析患者导管相关性感染的曲线下面积(AUC)大于血清miRNA-15a水平单独检测(P＜0.05).置管部位为股内静脉、miRNA-21≥0.82为血液透析患者导管相关性感染的影响因素(P＜0.05).结论 血清miRNA-21表达异常变化及置管部位为股内静脉是慢性肾小球肾炎血液透析患者导管相关性感染的影响因素,且血清miRNA-15a、、miRNA-21水平联合检测对感染具诊断价值.
Abstract
OBJECTIVE To explore the influencing factors for catheter-related infection in the chronic glomerulone-phritis patients undergoing hemodialysis and analyze the expressions of serum miRNA-15a and miRNA-21.METHODS A total of 97 patients with chronic glomerulonephritis who underwent hemodialysis in Sir Run Run Shaw Hospital Affiliated to Zhejiang University from Jun 2021 to Jun 2023 were recruited as the research subjects.The distribution of pathogens isolated from the patients with catheter-related infection was observed.The value of serum miRNA-15a and miRNA-21 in assessment of the infection and the influencing factors for the catheter-relat-ed infection were analyzed.RESULTS The incidence rate of catheter-related infection was 19.59％among the chro-nic glomerulonephritis patients,and there were 14 cases of bloodstream infection and 5 cases of local infection.To-tally 19 strains of pathogens were isolated from the 19 patients with catheter-related infection,and the isolation rate of gram-positive bacteria was the highest.The serum miRNA-15a level of the infection group was significantly lower than that of the no infection group,while the miRNA-21 of the infection group was significantly higher than that of the no infection group(P＜0.05).The receiver operating characteristic(ROC)curve showed that the area under curve(AUC)of the joint detection of the serum indexes was significantly higher than that of the single de-tection of serum miRNA-15a in diagnosis of the catheter-related infection in the hemodialysis patients(P＜0.05).Femoral venous catheterization and miRNA-21 no less than 0.82 were the influencing factors for the catheter-relat-ed infection(P＜0.05).CONCLUSION The abnormal expression of serum miRNA-21 and femoral venous catheteriza-tion are the influencing factors for the catheterrelated infection in the chronic glomerulonephritis patients undergoing he-modialysis.The joint detection of serum miRNA-15a and miRNA-21 has value in diagnosis of the infection.
