概括
在哥伦比亚尿路感染 (UTI) 中,不建议使用Tumbarello评分系统来识别扩展光谱β-乳糖酶 (ESBL) 引起的感染. 高ESBL患病率使得这种工具无效,可能导致过度使用广谱抗生素.
科学领域:
- 传染性疾病 传染性疾病
- 临床微生物学 临床微生物学
- 抗微生物耐药性 抗微生物耐药性
背景情况:
- 由扩展谱β-乳糖酶 (ESBL) 引起的尿路感染 (UTIs) 肠道细菌是一个越来越令人担忧的问题.
- 开发有效的策略来识别患有ESBL产生感染风险的患者对于适当的抗生素选择至关重要.
- 风险评估工具的本地验证是必要的,特别是在ESBL流行率高的地区.
研究的目的:
- 验证Tumbarello评分系统,用于识别哥伦比亚住院尿路感染患者的ESBL生产者.
- 在ESBL产生大肠杆菌的高发病率环境中评估修改后的Tumbarello评分的诊断性能.
主要方法:
- 在哥伦比亚波哥大 (Bogotá,哥伦比亚,2013-2020年) 住院患有炎炎的817名患者进行了回顾性队列研究.
- 对修改的Tumbarello评分 (不包括设施间转移) 的评估,以预测ESBL的存在.
- 使用曲线下面面积 (AUC) 分析ESBL和头素耐药性的诊断性能.
主要成果:
- 修改后的Tumbarello评分 (切断值≥6) 显示了低灵敏度 (18%) 和中等特异性 (83%).
- 预测ESBL存在的AUC为0.47,表明预测能力差.
- 该得分未能有效预测对第三代 (AUC = 0.49) 和第二代 (AUC = 0.51) 类素的耐药性.
结论:
- 由于ESBL * E. coli* 的高流行率,不建议使用Tumbarello指数来管理哥伦比亚的尿路感染.
- 它的使用可能会导致不必要的广泛抗生素利用.
- 需要进一步的研究,为ESBL生产者在高流行环境中开发准确的风险评估工具.

Urine Studies II: Urine Culture and Sensitivity Test
860
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
