摘要:

目的 了解2016—2019年福建省结核病耐药监测点分离的MTB的耐药情况,分析耐药变化趋势,为结核病防控工作提供依据。方法 收集2016—2019年全省9个耐药监测点培养阳性的分枝杆菌临床分离株,采用对硝基苯甲酸/噻吩-2-羧酸肼(PNB/TCH)生长试验法进行菌种初步鉴定。对MTB菌株进行异烟肼(INH)、利福平(RFP)、链霉素(Sm)、乙胺丁醇(EMB)、卡那霉素(Km)、氧氟沙星(Ofx)、卷曲霉素(Cm)、丙硫异烟胺(Pto)、对氨基水杨酸(PAS)共9种抗结核药品的敏感性试验,描述耐药谱和耐药水平。 结果 1434株MTB菌株中有1261株分离自初治患者,173株分离自复治患者。总耐药率为19.04%(273/1434),单耐药率为11.65%(167/1434),多耐药率为3.56%(51/1434),耐多药率为3.84%(55/1434)。复治患者的总耐药率(28.90%,50/173)和耐多药率(12.14%,21/173)均明显高于初治患者[总耐药率为17.68%(223/1261),耐多药率为2.70%(34/1261)],差异均有统计学意义(χ2=12.419,P=0.000;χ2=36.775,P=0.000)。耐药谱有42种,耐药菌株对9种抗结核药品的任一耐药率依次为:Sm(9.90%,142/1434)>INH(8.30%,119/1434)>RFP(5.93%,85/1434)>Ofx(3.63%,52/1434)>EMB(2.30%,33/1434)>Km(0.98%,14/1434)>Cm(0.77%,11/1434)、PAS(0.77%,11/1434)>Pto(0.63%,9/1434)。2016—2019各年度的总耐药率分别为17.69%(66/373)、22.34%(63/282)、20.31%(78/384)、16.71%(66/395),差异无统计学意义(χ趋势 2=0.248,P=0.619)。结论 福建省耐药处于较低水平,耐药呈复杂性和多样性,应重视患者的耐药筛查,加强耐药患者的治疗管理。

Abstract:

Objective To understand the drug resistance of Mycobacterium tuberculosis complex isolates from the drug-resistant surveillance sites in Fujian province from 2016 to 2019, and to analyze the trend of change in drug resistance, in order to provide reference for tuberculosis control. Methods The culture positive isolates from 9 drug-resistant surveillance sites in Fujian province were identified by PNB and TCH, and the Mycobacterium tuberculosis complex (MTPC) strains were performed the drug susceptibility test by proportion method. The tested 9 drugs included INH, RFP, SM, EMB, Km, Ofx, Cm, Pto and PAS. The drug resistance spectrum and resistant level was described. Results Among the 1434 MTPC strains, 1261 strains were isolated from new cases and 173 were isolated from re-treated cases. The overall drug resistance rate was 19.04% (273/1434), the mono-resistance rate was 11.65% (167/1434), the poly-resistance rate was 3.56% (51/1434), and the MDR rate was 3.84% (55/1434). The overall drug resistance rate (28.90%, 50/173) and MDR rate (12.14%, 21/173) in the retreated cases were significantly higher than those (17.68% (223/1261), 2.70% (34/1261)) in the new cases (χ2=12.419, P=0.000;χ2=36.775, P=0.000).The spectrum consisted of 42 different typed of drug resistance. Resistance rate of 9 drugs were Sm (9.90%, 142/1434), INH (8.30%, 119/1434), RFP (5.93%, 85/1434), Ofx (3.63%, 52/1434), EMB (2.30%, 33/1434), Km (0.98%, 14/1434), Cm (0.77%, 11/1434), PAS (0.77%, 11/1434), Pto (0.63%, 9/1434). The overall drug resistance rates from 2016 to 2019 were 17.69% (66/373), 22.34% (63/282), 20.31% (78/384) and 16.71% (66/395) respectively, which showed no trend of change (χtrend 2=0.248, P=0.619). Conclusion The drug resistance in Fujian province is at a low level and shows complex and diversity. It is necessary to pay attention to the screening of drug resistance and strengthen the treatment management of drug resistant patients.
