摘要:

目的 探究2014-2020年广东省期间各年龄段结核病患者的耐药特征与应对防治策略。 方法 以2014-2020年广东省32个结核病耐药监测点中,确诊结核病患者的39 048株结核分枝杆菌(mycobacterium tuberculosis, MTB)临床分离株为研究对象,回顾性分析耐药结核病患者及实验室相关资料,并以年龄、地区进行分组,探讨MTB临床分离株对药物的耐药性趋势、耐药结核病(包括单耐药结核病(monodrug?resistant tuberculosis, MR-TB)、多耐药结核病(poly-resistant tuberculosis, PDR-TB)、耐多药结核病(multidrug?resistant tuberculosis, MDR-TB)和广泛耐药结核病(extensively drug-resistant tuberculosis, XDR-TB)的发病率差异,以及MTB临床分离株对重点药物(利福平和氧氟沙星)的耐药情况。 结果 2014-2020年广东省32个结核病耐药监测点患者MTB临床分离株对9种抗结核药物在不同年度间、不同年龄段间的耐药率差异均无统计学意义(均P > 0.05)。MTB临床分离株的单耐药率、多耐药率、耐多药率、广泛耐药率和总耐药率分别为14.46%、5.16%、4.58%、1.29%。儿童组患者MTB临床分离株单耐药率(15.4%)高于青壮年组及老年组;青壮年组(5.0%)和老年组(5.0%)患者MTB临床分离株耐多药率高于儿童组患者;老年组患者MTB临床分离株广泛耐药率(2.1%)高于儿童组及青壮年组,差异均有统计学意义(P < 0.001)。来自珠三角地区的患者MTB临床分离株的单耐药率(14.8%)、多耐药率(5.3%)、耐多药率(4.7%)、广泛耐药率(1.4%)、耐氧氟沙星率(11.33%)和耐利福平率(6.92%)明显高于非珠三角地区,差异均有统计学意义(P < 0.001)。 结论 根据监测点数据,2014-2020年间,广东省耐药结核病的流行趋势平缓。但在特定人群(如儿童和老年人)中,耐药结核病的发病率较高,且珠三角地区的耐药结核病发病率和重点药物耐药率均高于广东省其他地区,值得进一步关注和采取防控策略。

Abstract:

Objective To evalute the drug resistance characteristics of tuberculosis(TB) patients of all ages in Guangdong Province during 2014-2020, and provide prevention and treatment strategies of tuberculosis. Method We used 39,048 clinical isolates of Mycobacterium tuberculosis (MTB) belonging to patients with confirmed TB from 2014 to 2020, from 32 TB drug?resistant surveillance sites in Guangdong Province, and we retrospectively analyzed the laboratories data of patients with drug?resistant TB, and grouped patients by age and region, to explore the trend of drug?resistance of MTB clinical isolates, the trend and incidence differences of multi?resistant TB (including monodrug?resistant TB (MR?TB), polydrug?resistant TB (PDR?TB), multidrug?resistant TB (MDR?TB) and extensively drug?resistant TB (XDR?TB)), and resistance characteristics of MTB clinical isolates to drugs in focus (rifampicin and ofloxacin). Result The differences in the resistance rates of MTB clinical isolates to nine antituberculosis drugs among patients at 32 TB drug resistance surveillance sites in Guangdong Province from 2014 to 2020 were not statistically significant (P > 0.05). The rates of MR?TB, PDR?TB, MDR?TB, XDR?TB, and total resistance isolates of MTB clinical isolates were 14.46%, 5.16%, 5.16%, 4.58%, and 1.29%, respectively. he pediatric group had a higher MR rate (15.4%) than the adult and geriatric groups, while the adult and geriatric groups had higher MDR rates (5.0% and 5.0%, respectively). The geriatric group also had a higher XDR rate (2.1%), with statistically significant differences (P < 0.001). The rates of MR?TB (14.8%), PDR?TB (5.3%), MDR?TB (4.7%), XDR?TB (1.4%), ofloxacin resistance (11.33%) and rifampicin resistance (6.92%) of MTB clinical isolates were higher in patients from the Pearl River Delta than in other regions of Guangdong Province, with statistically significant differences (P < 0.001). Conclusion According to the data from the surveillance sites, the epidemiological trend of drug?resistant TB in Guangdong Province is leveling off during the period 2014?2020. However, the incidence of drug?resistant TB is higher in specific populations (e.g. children and the elderly), and the incidence of drug?resistant TB and the rate of drug resistance to drugs in focus are higher in the Pearl River Delta than in other regions of Guangdong Province, necessitating further investigation and the development of novel prevention and control strategies.
