摘要:

目的: 分析甘肃省传染病医院2022—2024年结核分枝杆菌(Mycobacterium tuberculosis,MTB)临床分离株的耐药情况,为甘肃省耐药结核病的精准防控、治疗提供科学依据。方法: 选取甘肃省传染病医院2022—2024年从痰液或者肺泡灌洗液中培养鉴定的2941株MTB临床分离株,收集菌株对9种抗结核药物[包括异烟肼(INH)、利福平(RFP)、乙胺丁醇(EMB)、左氧氟沙星(Lfx)、丙硫异烟胺(Pto)、对氨基水杨酸钠(PAS)、莫西沙星(Mfx)、卷曲霉素(Cm)、阿米卡星(Am)]的药物敏感性试验(简称“药敏试验”)结果并进行分析。结果: 2941株MTB中敏感株占62.39%(1835/2941),耐药株占37.61%(1106/2941)。菌株的单耐药率为7.14%(210/2941),多耐药率为12.58%(370/2941),耐多药率为11.39%(335/2941),广泛耐药率为6.49%(191/2941)。9种抗结核药物的耐药顺位依次为:INH(28.66%,843/2941)、RFP(20.50%,603/2941)、Lfx(10.34%,304/2941)、Mfx(9.49%,279/2941)、EMB(8.06%,237/2941)、PAS(1.73%,51/2941)、Pto(1.67%,49/2941)、Cm(0.92%,27/2941)、Am(0.78%,23/2941)。耐药谱共计71种,包括单耐药谱8种,多耐药谱26种,耐多药谱15种,广泛耐药谱22种。结论: 甘肃省传染病医院肺结核患者MTB临床分离株耐药率较高,以多耐药和耐多药为主,耐药谱呈现复杂性和多样性,应重视肺结核患者的耐药筛查,强化耐药患者的监测。

Abstract:

Objective: To analyze the drug resistance of clinical isolates of Mycobacterium tuberculosis (MTB) in Gansu Provincial Infectious Diseases Hospital from 2022 to 2024, so as to provide scientific basis for precise prevention, control and treatment of drug-resistant tuberculosis in Gansu Province. Methods: A total of 2941 clinical isolates of MTB cultured and identified from sputum or bronchoalveolar lavage fluid in Gansu Provincial Infectious Disease Hospital from 2022 to 2024 were selected. The results of drug sensitivity tests on 9 anti-tuberculosis drugs, including isoniazid (INH), rifampicin (RFP), ethambutol (EMB), levofloxacin (Lfx), propiconazole (Pto), sodium aminosalicylate (PAS), moxifloxacin (Mfx), capreomycin (Cm), and amikacin (Am), were collected and analyzed. Results: Among 2941 clinical isolates of MTB, drug sensitive strains accounted for 62.39% (1835/2941) and drug-resistant strains accounted for 37.61% (1106/2941). The single drug resistance rate of the strain was 7.14% (210/2941), the poly-drug resistance rate was 12.58% (370/2941), the multi-drug resistance rate was 11.39% (335/2941), and the extensive-drug resistance rate was 6.49% (191/2941). The resistance sequence of the 9 anti-tuberculosis drugs as follows: INH (28.66%, 843/2941), RFP (20.50%, 603/2941), Lfx (10.34%, 304/2941), Mfx (9.49%, 279/2941), EMB (8.06%, 237/2941), PAS (1.73%, 51/2941), Pto (1.67%, 49/2941), Cm (0.92%, 27/2941), Am (0.78%, 23/2941). There were a total of 71 drug resistance spectra, including 8 single drug resistance spectra, 26 poly-drug resistance spectra, 15 multi-drug resistance spectra, and 22 extensive-drug resistance spectra. Conclusion: The clinical isolates of MTB from tuberculosis patients in Gansu Provincial Infectious Diseases Hospital have a high resistance rate, mainly poly-drug resistance and multi-drug resistance. The resistance spectrum presents complexity and diversity, and drug resistance screening of tuberculosis patients should be emphasized, and monitoring of drug-resistant patients should be strengthened.
