摘要:

目的:分析初治和复治结核分枝杆菌痰培养阳性的肺结核患者对4种一线抗结核药的耐多药(MDR)情况,了解抗结核药耐药现状和形势。方法:选取结核分枝杆菌痰培养阳性患者395例,按中国防痨协会《结核病诊断细菌学检验规程》的要求进行菌种鉴别试验。采用WHO推荐比例法对阳性分离菌株进行药物敏感性检测,计算每种一线药的耐药率及4种一线药的MDR情况。计算初、复治患者的MDR率。结果:4种一线抗结核药物耐药率顺位依次为链霉素(93/395,23.5%),异烟肼(88/395,22.3%),利福平(58/395,14.7%),乙胺丁醇(23/395,5.8%)。初治和复治组患者耐药均以耐链霉素和异烟肼为主,且耐药顺位一致,复治组患者利福平耐药率(17.4%)高于初治组(6.9%)(χ2=6.714,P=0.010)。至少同时对异烟肼和利福平耐药者33例,总MDR率为8.4%,复治患者MDR率(10.2%)高于初治患者MDR率(2.9%)(χ2=5.263,P=0.022)。初、复治组患者MDR形式均以同时耐异烟肼、利福平和链霉素为主,分别为2例(2.0%)和13例(4.4%)。结论:结核分枝菌痰培养阳性肺结核患者耐药频度顺位依次为链霉素、异烟肼、利福平和乙胺丁醇。复治组患者利福平耐药率、MDR率均高于初治组。初、复治组耐多药形式均以同时耐异烟肼、利福平和链霉素为主。

Abstract:

Objective To analyze the multidrug resistant(MDR) situation of initial and retreatment tuberculosis patients with positive sputum Mycobacterium tuberculosis culture to four frontline anti-tuberculosis (anti-tb) drugs, and to learn the resistance status and situation of anti-tb drugs. Methods A total of 395 patients with positive sputum Mycobacterium tuberculosis culture were selected.The species identification experiment was carried out according to the China Tuberculosis Association Tuberculosis Diagnostic Bacteriology Inspection Procedures.The drug sensitivities of positive isolates sputum were detected by WHO recommended ratio method.The risistant rates of each first-line drug and MDR situation of the four kinds of first-line drugs were calculated.The multi-drug resistant rate of the patients in initial and retreatment groups were detected. Results The order of resistant rates of four first-line anti-tb drugs in the 395 patients were streptomycin (93/395,23.5%),isoniazid (88/395,22.3%),rifampin (58/395,14.7%),ethambutol (23/395,5.8%).The patients in initial treatment group and retreatment group were resistant to streptomycin and isoniazid,and the resistance order was consistent;the resistant rate of rifampin(17.4%) of the patients in retreatment group was higher than that in initial group (6.9%) (χ2=6.714,P=0.010).At the same time there were at least 33 cases of isoniazid and rifampin resistance,and the total MDR rate was 8.4%;the MDR rate of the patients in retreatment group (10.2%) was higher than that in initial group (2.9%) (χ2=5.263,P=0.022). The main MDR forms of the patients in initial(2,2.0%) and retreatment(13,4.4%) groups were resistant to isomiazid,rifampin,and streptomycin. Conclusion The order of drug-resistant is streptomycin,isoniazid,rifampicin,and ethambutol.The resistant rate of rifampin and the MDR rate of the patients in retreatment group are higher than those in initial group.The main MDR forms of patients in initial and retreatment groups are resistant to isomiazid,rifampin,and streptomycin.
