摘要: 目的 了解河南省濮阳市涂阳肺结核耐药结核病的流行现状和特点,为今后结核病防治工作提供参考依据。方法 收集2010年3月1日至2013年2月28日全市结核病防治机构发现的1291例涂阳肺结核患者的痰标本,进行分枝杆菌培养,用比例法进行6种抗结核药物(H、R、E、S、Ofx、Km)敏感性试验。经培养阳性、菌型鉴定为结核分枝杆菌且药敏试验成功的1119例为研究对象,其中,初治患者1017例,复治患者102例,并对1119株结核分枝杆菌的药敏试验结果进行分析。计数资料组间比较采用χ2检验,P<0.05为差异有统计学意义。结果  1119株结核分枝杆菌对6种抗结核药物的总耐药率、单耐药率、多耐药率、耐多药率分别为37.2%(416/1119)、24.3%(272/1119)、8.2%(92/1119)、4.5%(50/1119)。在总耐药方面,其中初治患者耐药率35.1%(357/1017),复治患者耐药率57.8%(59/102);复治患者耐药率明显高于初治患者,两者间差异有统计学意义(χ2=20.525,P<0.05)。对6种抗结核药物的耐药率由高到低的顺序是:H(19.9%,223/1119)、S(19.5%,218/1119)、R(10.8%,121/1119)、Ofx(3.7%,14/1119)、E(3.6%,40/1119)、Km(1.4%,16/1119)。初治患者单耐药率为24.3%(247/1017),复治患者单耐药率为24.5%(25/102),两者之间差异无统计学意义(χ2=0.002,P>0.05)。初治患者多耐药率为7.9%(80/1017),复治患者多耐药率为11.8%(12/102),两者间差异无统计学意义(χ2=1.867,P>0.05)。初治患者耐多药率为2.9%(30/1017);复治患者耐多药率为19.6%(20/102);两者间差异具有统计学意义(χ2=56.423,P=0.000)。结论 濮阳市1119例涂阳肺结核患者的耐药结果,反映了本地区耐药结核病的实际水平,为今后结核病防治、特别是耐药结核病防治,及时采取干预措施、更有效地控制疫情奠定了基础。

Abstract: Objective  To understand the epidemic situation and features of drug resistance of smear positive pulmonary tuberculosis (TB) in Puyang city of He’nan province, and to provide reference for TB control and prevention. Methods  The sputum samples of 1291 smear positive PTB patients detected in TB control institutes in Puyang from 1 March 2010 to 28 February 2013 were collected and cultured, proportion method of tubercle bacillus drug sensitivity test (DST) was conducted to 6 anti-TB drugs (H, R, E, S, Ofx, Km). One thonsand one hundred and nineteen Mycobacterium tuberculosis strains (of 1017 new patients and 102 retreated cases) with culture positive results and DST results were treated as the study object, and the DST results were analyzed. Chi-square test was used for categorical data comparison, P<0.05 was considered as statistically significant. Results The overall drug resistant rate, monoresistance rate, polyresistance rate and multidrug-resistance (MDR) rate were 37.2% (416/1119), 24.3% (272/1119), 8.2% (92/1119) and 4.5% (50/1119) respectively. The overall drug resistance rate was 35.1% (357/1017) among new cases and 57.8% (59/102) among previously treated cases. There was significant difference between the two groups (χ2=20.525, P<0.05). The drug resistance rates to 6 anti-TB drugs arranged in descending order were H (19.9%, 223/1119), S (19.5%, 218/1119), R (10.8%, 121/1119), Ofx (3.7%,14/1119), E (3.6%, 40/1119) and Km (1.4%, 16/1119). The monoresistance rate was 24.3% (247/1017) among new cases and 24.5% (25/102) among previously treated cases, and the difference was not statistical significant (χ2=0.002, P>0.05). The polyresistance rate was 7.9% (80/1017) among new cases and 11.8% (12/102) among previously treated cases, there was no significant difference between the two groups (χ2=1.867, P>0.05). MDR rate was 2.9% (30/1017) among new cases, which was significantly lower than that among previously treated cases (19.6%, 20/102) (χ2=56.423, P=0.000). Conclusion  The drug resistance results of 1119 smear positive TB cases reflect the actual level of drug resistance in Puyang, which lay the foundation for TB control and prevention, especially drug resistant TB control and prevention, taking interventions in time and controlling the epidemic more effectively in future.
