    目的 探讨医院获得性耐万古霉素肠球菌(VRE)尿路感染的临床特征及其危险因素,为临床防控提供依据。方法 选取2021年1月—2023年10月广东省某三级甲等医院医院获得性VRE尿路感染患者作为VRE组,采用1 ∶2 病例-对照研究方法,选取万古霉素敏感肠球菌(VSE)尿路感染患者作为VSE组。比较分析两组患者的临床特征,并采用单因素、logistic多因素回归分析医院获得性VRE尿路感染的危险因素。结果 共纳入VRE组患者32例、VSE组患者64例。VRE组患者以女性(68.75%),年龄≥60岁(71.88%),重症监护病房(ICU,占56.25%)来源为主,病原菌以耐万古霉素屎肠球菌(VREfm,占96.87%)为主。VRE组患者发热、腰痛临床症状比例及降钙素原(PCT)、C反应蛋白(CRP)水平均高于VSE组(均P<0.05)。logistic回归分析结果显示,合并肺部感染(OR=6.890, 95%CI:1.098~43.218,P=0.039)、高血压病史(OR=4.240,95%CI:1.084~16.581, P=0.038)和感染前头孢菌素类抗生素暴露(OR=4.642,95%CI:1.270~16.967,P=0.020)是医院获得性VRE尿路感染的独立危险因素。VRE组检出肠球菌32株,VSE组检出肠球菌64株,VRE对环丙沙星、阿莫西林、氨苄西林、青霉素G、四环素、高浓度庆大霉素及左氧氟沙星的耐药率高于VSE(均P<0.05)。结论 医院获得性VRE尿路感染者常合并多种基础疾病且营养状况不佳,对多种抗菌药物高度耐药,临床应重点关注合并肺部感染、高血压病史和头孢菌素类抗生素暴露的患者。

    Abstract:

    Objective To evaluate the clinical characteristics and risk factors of healthcare-associated urinary tract infection (HA-UTI) due to vancomycin-resistant Enterococcus (VRE), and provide basis for clinical prevention and control. Methods Patients with VRE HA-UTI in a tertiary first-class hospital in Guangdong Province from January 2021 to October 2023 were selected as the VRE group. A 1 ∶2 case-control study method was conducted to select patients with vancomycin-sensitive Enterococcus (VSE) UTI as the VSE group. Clinical characteristics of two groups of patients were compared and analyzed. Risk factors for VRE HA-UTI were analyzed using univariate regression and logistic multivariate regression. Results A total of 32 patients in the VRE group and 64 patients in the VSE group were included in the analysis. In VRE group, most patients were female (68.75%), aged ≥60 years (71.88%), and from intensive care unit (ICU, 56.25%). The main detected pathogen was vancomycin-resistant Enterococcus faecium (VREfm, 96.87%). The proportion of clinical symptoms such as fever and lumbago as well as the levels of procalcitonin (PCT) and C-reactive protein (CRP) in patients in the VRE group were all higher than those in the VSE group (all P<0.05). Logistic regression analysis results showed that concomitant pulmonary infection (OR=6.890, 95%CI: 1.098-43.218, P=0.039), history of hypertension (OR=4.240, 95%CI: 1.084-16.581, P=0.038), and cephalosporin antibiotic exposure before infection (OR=4.642, 95%CI: 1.270-16.967, P=0.020) were independent risk factors for VRE HA-UTI. There were 32 and 64 strains of Enterococcus detected from VRE group and VSE group, respectively. VRE had higher resistance rates to ciprofloxacin, amoxicillin, ampicillin, penicillin G, tetracycline, high concentration gentamicin, and levofloxacin than VSE (all P<0.05). Conclusion Patients with VRE HA-UTI often have multiple underlying diseases and poor nutritional status, and are highly resis-tant to multiple antimicrobial agents. Clinical attention should be focused on patients with concomitant pulmonary infection, history of hypertension, and exposure to cephalosporin antibiotics.
