摘要:

目的: 明确中国异烟肼(INH)耐药结核分枝杆菌基因突变的分子特征。方法: 在PubMed、中国知网、万方、维普数据库中检索有关中国结核分枝杆菌耐INH基因突变的研究文献,对纳入文献的突变基因的突变位点、突变类型,以及氨基酸改变数量等信息进行整合分析。结果: 共纳入69篇中英文文献,共6393株INH耐药结核分枝杆菌。95.71%(6119/6393)检测到基因突变或缺失,其中katGinhAaphC突变数量最多,分别占77.57%(4959/6393)、15.20%(972/6393)、3.69%(236/6393)。单基因单位点突变占87.80%(5613/6393),联合突变占12.20%(780/6393)。katG315突变占INH耐药菌株总数的56.22%(3594/6393),katG463突变占10.03%(641/6393),inhA15突变占10.10%(646/6393)。突变形式最常见的是C→T,占10.03%(641/6393)。结论:中国INH耐药结核分枝杆菌突变基因最多的是katGinhAahpC,突变密码子最多的是katG315katG463inhA15

Abstract:

Objective: To clarify the gene mutation characteristics of isoniazid (INH)-resistant Mycobacterium tuberculosis in China. Methods: We searched for literatures on INH-resistant gene mutations of Mycobacterium tuberculosis in China in PubMed, CNKI, Wanfang, and Weipu databases, and then conducted integrated analysis on mutation points and types of mutations, and numbers of amino acid changes reported in the literatures. Results: A total of 69 Chinese and English literatures were included with data of 6393 strains of isoniazid-resistant Mycobacterium tuberculosis within which 95.71% (6119/6393) had gene mutations or deletions. Among them, katG, inhA, and ahpC were most frequently observed mutation genes, accounting for 77.57% (4959/6393), 15.20% (972/6393), 3.69% (236/6393) of all strains respectively. Single gene single point mutations accounted for 87.80% (5613/6393), and combined mutations accounted for 12.20% (780/6393). katG315, katG463 and inhA15 mutations accounted for 56.22% (3594/6393), 10.03% (641/6393) and 10.10% (646/6393) of all strains respectively. The most common form of mutation was C→T, accounting for about 10.03% (641/6393). Conclusion: The most common mutated genes of isoniazid-resistant Mycobacterium tuberculosis were katG, inhA, ahpC, while the most mutated codons were katG315, katG463, inhA15 in China.
