摘要:

抗微生物药物耐药性的出现, 特别是由耐碳青霉烯类革兰氏阴性菌引起的医院感染, 是全球性重大公共卫生问题。碳青霉烯类抗菌药物的广泛使用, 使细菌对此类药物的耐药性逐渐增强。本研究旨在分析碳青霉烯类抗菌药物的消耗量与四种革兰氏阴性菌耐药率之间的关系, 包括大肠埃希菌(Escherichia coli, EC)、肺炎克雷伯菌(Klebsiella pneumoniae, KP)、鲍曼不动杆菌(Acinetobacter baumannii, AB)和铜绿假单胞菌(Pseudomonas aeruginosa, PA)。本研究纳入了郑州大学第一附属医院2010年1月至2022年12月的回顾性数据。通过Mann-Kendall趋势检验和Sen’s斜率估计法分析碳青霉烯类药物消耗量和耐药率的变化趋势和幅度, Spearman相关性分析两者相关性。美罗培南、亚胺培南、比阿培南和碳青霉烯类药物的消耗量均显著增加(|Z| > 1.96, SS > 0); EC和KP对美罗培南或亚胺培南的耐药率显著增加(|Z| > 1.96, SS > 0); EC对美罗培南的耐药率与美罗培南的用药频度(DDDs)呈显著性正相关(r = 0.732, P < 0.05); EC对亚胺培南的耐药率与亚胺培南的DDDs间存在显著性正相关(r = 0.49, P < 0.05); KP对美罗培南和亚胺培南的耐药率与两种药物的DDDs间也呈显著性正相关; 耐碳青霉烯类AB或PA与碳青霉烯的消耗量之间没有显著相关性。亚胺培南和美罗培南的DDDs与EC和KP耐药率呈显著性正相关, 临床应严格控制和管理碳青霉烯类药物的使用, 以遏制或延缓细菌耐药性的出现。

Abstract:

The rise of antimicrobial resistance, particularly in healthcare-associated infections caused by carbapenem-resistant Gram-negative pathogens, poses a critical global challenge. The extensive use of carbapenems has exacerbated this issue by increasing selective pressure within bacterial populations. This study aimed to investigate the association between carbapenem consumption and resistance rates in four priority Gram-negative bacteria: Escherichia coli (EC), Klebsiella pneumoniae (KP), Acinetobacter baumannii (AB), and Pseudomonas aeruginosa (PA). Retrospective data were collected from the First Affiliated Hospital of Zhengzhou University, covering the period from January 2010 to December 2022. Trends in carbapenem consumption and resistance were analyzed using the Mann-Kendall test to assess statistical significance and the Sen’s slope (SS) estimator to determine the magnitude of change. Correlations between carbapenem use and bacterial resistance rates were evaluated via Spearman correlation analysis. Over the study period, the consumption of meropenem, imipenem, biapenem, and total carbapenems exhibited a significant upward trend (|Z| > 1.96, SS > 0). Correspondingly, the resistance rates of EC and KP to meropenem and imipenem also increased significantly (|Z| > 1.96, SS > 0). A strong positive correlation was observed between the resistance rate of EC to meropenem and the defined daily doses (DDDs) of meropenem (r = 0.732, P < 0.05) and between EC resistance to imipenem and its DDDs (r = 0.49, P < 0.05). Similar significant correlations were identified for KP. However, no significant associations were found between carbapenem resistance in AB or PA and carbapenem consumption. These findings underscored the strong correlation between carbapenem use and the resistance rates of EC and KP, highlighting the urgent need for stringent control and stewardship of carbapenem use in clinical settings to mitigate or delay the development of bacterial drug resistance.
