Abstract

Objective

We analyse the effectiveness of short courses of adequate treatment in patients with episodes of carbapenemase-producing Enterobacterales bloodstream-infections (CPE-BSI).

Methods

Patients with first monomicrobial CPE-BSI episodes who received ≥72 h of appropriate treatment from 2014–2022 were selected. Detection of CPE was established on the basis of phenotypic antibiogram and confirmation by PCR and/or immunochromatographic methods. Patients were classified in short treatment group (STG) those who received 3–10 days of appropriate treatment, and long treatment (LTG) those receiving >10 days. Unfavourable outcome consisted in a composite of global 30-day mortality and/or persistent bacteremia and/or recurrent bacteremia. Inverse probability of treatment weighting (IPTW) analysis was performed to compare the outcome between the two study groups.

Results

We included 105 CPE-BSI episodes: 99 were caused by OXA-48-like, 4 VIM and 2 KPC carbapenemases. Thirty-nine patients (37.1%) were included in the STG and 66 (62.9%) in LTG. The STG group presented frequent treatment with ceftazidime-avibactam (43.6% vs. 24.2%, P = 0.03) and lower in-hospital stay (21 days vs. 32 days, P = 0.02). Overall, 28 patients (26.7%) presented unfavourable outcome: IPTW analysis showed no differences in the outcome between STG to LTG groups (24.2% vs. 30.8%, weighted-risk difference 6.6%, P = 0.44). Patients with unfavourable outcome presented more frequently source other than urinary-biliary (46.4% vs. 23.4%, P = 0.02), received less frequently ceftazidime-avibactam (14.3% vs. 37.7%, P = 0.02) and presented frequently with absence of source control when indicated (28.6% vs. 13.0%, P = 0.06).

Conclusions

Short treatment durations for CPE-BSI episodes may be effective, as long as they are appropriate and source control is performed.

短期治疗血流感染中产碳青霉烯酶肠杆菌的有效性：一项回顾性队列研究。

目的我们分析了短期适当治疗对产碳青霉烯酶肠杆菌血流感染（CPE-BSI）患者的疗效：方法：选取2014-2022年间首次发生单微生物CPE-BSI且接受适当治疗≥72小时的患者。CPE 的检测以表型抗生素图为基础，并通过 PCR 和/或免疫层析方法进行确认。接受 3-10 天适当治疗的患者被分为短期治疗组（STG），接受 10 天以上治疗的患者被分为长期治疗组（LTG）。不良结局包括 30 天内的总死亡率和/或持续菌血症和/或复发性菌血症。为了比较两个研究组之间的结果，我们进行了逆概率治疗加权（IPTW）分析：我们共纳入了 105 例 CPE-BSI：99 例由 OXA-48 类、4 例 VIM 和 2 例 KPC 碳青霉烯酶引起。39名患者（37.1%）被纳入STG组，66名患者（62.9%）被纳入LTG组。STG组经常使用头孢他啶-阿维菌素治疗（43.6% 对 24.2%，P=0.03），住院时间较短（21 天对 32 天，P=0.02）。总体而言，28 名患者（26.7%）出现了不良预后：IPTW分析显示，STG组与LTG组的预后无差异（24.2% vs. 30.8%，加权风险差异为6.6%，P=0.44）。疗效不佳的患者更多地出现尿胆以外的感染源（46.4% vs. 23.4%，p=0.02），接受头孢他啶-阿维菌素治疗的比例较低（14.3% vs. 37.7%，p=0.02），在有指征的情况下经常出现未进行感染源控制的情况（28.6% vs. 13.0%，p=0.06）：结论：对 CPE-BSI 病例进行短期治疗可能是有效的，只要治疗得当并进行了病源控制。
