We performed a nested case-control study (ratio of 1:4) on the emergence of tigecycline-resistant multidrug-resistant Klebsiella pneumoniae (TR-MDRKP) isolates among patients who initially presented with a tigecycline-susceptible MDRKP isolate. Out of 260 patients, 24 (9%) had a subsequent clinical culture positive for a TR-MDRKP isolate within the 90-day follow-up period. On logistic regression analyses, receipt of tigecycline (adjusted odds ratio [OR], 5.06; 95% confidence interval [CI], 1.80 to 14.23; P = 0.002) was the only independent predictor of subsequent isolation of a TR strain.
我们对最初表现为替加环素敏感的多药耐药肺炎克雷伯菌(MDRKP)分离株的患者中出现替加环素耐药的多药耐药肺炎克雷伯菌(TR-MDRKP)分离株的情况进行了巢式病例对照研究(1:4 的比例)。在 260 名患者中,有 24 名(9%)在 90 天随访期间随后的临床培养呈 TR-MDRKP 分离株阳性。在逻辑回归分析中,替加环素的使用(调整后的优势比 [OR],5.06;95%置信区间 [CI],1.80 至 14.23;P = 0.002)是随后分离出 TR 株的唯一独立预测因子。
