甘肃省初治肺结核患者耐药现状及耐多药影响因素分析

目的分析甘肃省初治肺结核患者耐药现状及其影响因素, 为精准防控提供参考依据。方法纳入2014年9月至2017年8月甘肃省30家结核病定点医疗机构(耐药监测点)初治肺结核患者, 并进行问卷调查。临床分离的结核分枝杆菌进行异烟肼、利福平、乙胺丁醇、链霉素、卡那霉素、阿米卡星、氧氟沙星、卷曲霉素、丙硫异烟胺和对氨基水杨酸钠10种抗结核药物表型药敏(比例法)鉴定。采用logistic回归模型分析耐多药结核病产生的危险因素。结果 1 815例初治患者中, 1例患者对应1株结核分枝杆菌, 其中总耐药率、单耐药、多耐药、耐多药和广泛耐药率及其95%CI分别为25.45%(23.45%～27.46%)、11.40%(9.94%～12.87%)、6.23%(5.11%～7.34%)、7.82%(6.59%～9.06%)、0.28%(0.03%～0.52%);142例耐多药患者中, 农民、20～59岁青壮年及低收入者分别占90.85%、62.68%、31.69%。单因素及多因素分析结果显示, 男性、少数民族、治疗<1个月且停药<2个月为耐多药结核病的危险因素。结论与全国平均水平相比, 甘肃省初...

Current situation on drug resistance and influencing factors of multidrug-resistance in newly treated pulmonary tuberculosis patients in Gansu province

Objective In order to provide the precise prevention and control strategy of drug resistance TB in Gansu province, we analyzed the status and risk factors of new drug resistance pulmonary tuberculosis patients. Methods New pulmonary tuberculosis patients were enrolled from 30 tuberculosis-specialized medical institutions (drug resistance monitoring stations) in Gansu province between first September 2014 to 31^th August 2017, and filled in the survey questionnaire. The isolated Mycobacterium tuberculosis (MTB) strains were implemented 10 drugs drug- susceptibility tes, including isoniazid (INH), rifampicin (RFP), ethambutol (EMB), streptomycin (Sm), kanamycin (Km), amikacin (Am), ofloxacin (Ofx), capreomycin (Cm), propithio-iso-nicotinamide (Pto).The risk factors were analyzed by logistic regression model. Results One patient was corresponding one clinical isolates among 1 815 patients. The rate (95%CI) of total drug-resistance, single drugresistance, multiple drug- resistance, multidrug-resistance and extensively drug-resistant were 25.45% (23.45%-27.46%), 11.40% (9.94%-12.87%),6.23% (5.11%-7.34%), 7.82% (6.59%-9.06%) and 0.28% (0.03%-0.52%) respectively. Among 142 multidrug-resistant TB patients, the farmers, young adults aged 20-59 and low-income group were 90.85%, 62.68% and 31.69%, respectively. The results of univariate and multivariate analysis showed that the male, non-Han, treatment less than 1 month group and treatment less than 1 month and withdrawal less than 2 month group were risk factors of new multidrug-resistant pulmonary TB. Conclusions Compared with the Chinese national baseline level of TB resistance, the total drug resistance rate of new TB patients in Gansu province was low, but the multidrug-resistance rate was high. The health assistance for rural low-income TB patients was still an important strategy to prevent and control multidrug-resistant in Gansu province. And measures must implement to stop irregular treatment and poor compliance, as the risk factors of multidrug-resistance in new PTB patients.
