ObjectiveTo investigate the relationship between the mannose-binding lectin 2 (MBL2) codon 52 A/D gene polymorphism and tuberculosis risk by meta-analysis. MethodsThe Embase, PubMed, China National Knowledg Infrastructure, Wanfang databases were searched to identify domestic and foreign case-control studies involving the association between MBL2 codon 52 A/D gene polymorphism and tuberculosis risk from establishment of these database till May 20, 2015. Two reviewers collected data according to the inclusion and exclusion criteria, and extracted data and assessed quality of the literature. Meta analysis was performed by RevMan 5.2 software and Stata 10.0 software. ResultsIn total, 1 282 cases and 1 483 controls from nine case-control studies were included in this meta-analysis. According to the test of heterogeneity, there was statistical heterogeneity among these studies (P < 0.1). Thus, we conducted the analysis by the random effect model on the basis of heterogeneity test. The results indicated that MBL2 codon 52 A/D gene polymorphism might not be associated with risk of tuberculosis [DD+AD versus AA: OR=1.46, 95% CI (0.87, 2.43), P=0.15] in total analysis by random effect model. However, when stratifying separately according to ethnicity, a significant association between MBL2 codon 52 A/D gene polymorphism and tuberculosis risk was found in Asians [OR=1.96, 95% CI (1.27, 3.03), P=0.003 for DD+AD versus AA], but not among Caucasians [OR=1.36, 95% CI (0.52, 3.56), P=0.53 for DD+AD versus AA]. Conclusions The present meta-analysis indicates that the polymorphism of MBL2 codon 52 A/D may be a risk factor for TB in Asians. But the MBL2 codon 52 A/D gene polymorphism may not contribute to the risk of tuberculosis in Caucasians.

2010 年世界卫生组织( WHO) 年度报告指出, 中国2009 年有110 万至150 万名结核患者, 并且每 10 万人口中即有新增病例50 至99 人。报告中也提到, 近年吸毒人数增多, 世界范围内有11% ～ 13% 的结核患者呈HIV 阳性。而在中国, 虽然仅有 1. 5% 的新增结核患者显示HIV 阳性, 比2007 年的 1. 9% 略有下降, 但中国结核病群体巨大, 其形势仍不容忽视[ 1, 2 ] 。
目的:比较4种选药方案治疗复治后耐多药结核病的治疗疗效。方法:回顾性分析152例复治后耐多药结核病例,按治疗方案分为4组。Ⅰ组采用标准化疗方案HSRZE;Ⅱ组根据过去的治疗史组成个体化方案;Ⅲ组根据药敏试验组成个体化方案;Ⅳ组采用力克肺疾、左氧氟沙星、卷曲霉素、阿奇霉素、阿莫西林克拉维酸方案。结果:4组病灶吸收有效率分别为20.00%、47.37%、52.38%、81.48%;4组12个月疾菌阴转率分别为22.22%、57.89%、50.00%、81.48%。结论:对于所有复治肺结核患者均采用统一的标准复治方案有效率低,由力克肺疾、左氧氟沙星、卷曲霉素、阿奇霉素、阿莫西林克拉维酸联合组成的化疗方案是治疗复治后耐多药结核病的有效方案。
ObjectivesTo systematically review the disease burden and epidemiological characteristics of tuberculosis in the Chinese population, and to provide reference for health resources allocation and health policy making.MethodsDatabases such as PubMed, EMbase, CNKI, VIP and WanFang Data were searched for studies investigating disease burden of tuberculosis in Chinese population from inception to August 1st, 2017. Two researchers independently screened literature, exacted data and assessed methodological quality of included studies. Statistical analysis was performed on data of tuberculosis associated population, mortality and disease burden.ResultsA total of 40 studies were included. The results of qualitative analysis showed that, since 1990, the prevalence of tuberculosis and its disease burden in China decreased year by year. However, the disease burden per patient and the total economic burden in China showed an increasing trend, and the economical disease burden increased 1.6 times from 1993 to 2003. The disease burden of men was higher than that of women, and it was higher in the countryside than in the city. In 2004, the ratio of YLL per thousand people in rural and urban areas was 2.18, and the ratio was 1.29 in 2014. Additionally, the disease burden decreased gradually in western, central and eastern regions. In 2014, compared with 2004, YLL decreased by 1.11, while the central and eastern regions were 0.48 and 0.25, respectively. The gap between the gender, the urban and rural areas and the regions was not as significant as in previous.ConclusionsThe disease burden of tuberculosis in China is seriously high and the tuberculosis prevention and control work should take into consideration the epidemiological characteristics of tuberculosis and the trends of the disease burden. It is necessary to rationally and effectively implement health intervention programs and allocate health resources based on different health demands in different regions and age groups to reduce the morbidity and mortality, and to pay more attention to drug-resistant tuberculosis. Besides, the emphasis of prevention should be placed on reducing disease burden in the elderly and strengthening prevention in the young population.
Precision medicine is a novel medical modality based on genome sequencing, bioinformatics and big data science. The studies regarding tuberculosis always concentrated on the bacteria and host in the setting of precision medicine. This review mainly introduces the application of precision medicine in the diagnosis and treatment of tuberculosis. The limits of the Chinese studies with respect to precision medicine in tuberculosis are also discussed. Moreover, the article predicates its future development.
ObjectiveTo systematically review the diagnostic value of T-SPOT.TB and QuantiFERON-TB (QFT-GIT/QFT-Plus) in active tuberculosis (ATB). MethodsThe PubMed, Web of Science, Cochrane Library, EMbase, CNKI, WanFang Data, and CBM databases were electronically searched to collect diagnostic accuracy studies comparing QFT-GIT/QFT-Plus and T-SPOT.TB for diagnosing ATB from inception to February 8, 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies, then, meta-analysis was performed by using Stata 16.0 software. ResultsA total of 20 studies were included. The results of meta-analysis showed that the pooled sensitivity of T-SPOT.TB and QFT-GIT were 0.89 (95%CI 0.85 to 0.92) and 0.84 (95%CI 0.79 to 0.89), the pooled specificity were 0.85 (95%CI 0.68 to 0.93) and 0.86 (95%CI 0.72 to 0.94), the area under the curve (AUC) of summary receiver operating characteristic (SROC) were 0.93 (95%CI 0.84 to 0.97) and 0.90 (95%CI 0.56 to 0.99), respectively. The pooled sensitivity of T-SPOT.TB and QFT-Plus were 0.93 (95%CI 0.81 to 0.97) and 0.93 (95%CI 0.89 to 0.96), specificity were 0.99 (95%CI 0.39 to 1.00) and 0.94 (95%CI 0.67 to 0.99), the AUC of SROC were 0.99 (95%CI 0.67 to 1.00) and 0.98 (95%CI 0.65 to 1.00), respectively. ConclusionBoth T-SPOT.TB and QFT have high diagnostic accuracy for ATB, and the diagnostic sensitivity of T-SPOT.TB is better than QFT-GIT. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
Objective To investigate and analyze the past and on-going pro-poor programs related to health equity, and the relevant policies, documents, interventions measures, etc. to improve the China prisoners’ accessibility and utilization of tuberculosis (TB) control services in TB control programs, then evaluate their impacts and influences to provide evidences and suggestions for the further work of TB prevention and treatment. Methods Retrieve published documents about TB prevention and treatment of transient population dating from 1998 to 2008 from MEDLINE, PubMed, CNKI, CBMdisc CDDB and VIP with computers. Simultaneously, a series of interviews was conducted after we got the agreement of the interview people by using non-probability statistics methods. Results A total of 23 documents were retrieved, and they were consonant with the criteria, among which 8 were published and 5 were policy documents. The study on the second document showed the measures that presently applied on TB patients among prisoners in China: find patients through surveys, inspect every prisons and patients going to visit doctors with symptoms; concerning differences between various groups of prisoners, the measure of “classify and instruction, enroll together and treat” was applied; carry out health education in the prisons and so on. After the implement of various measures, the knowledge awareness, discovery rate, accomplishment ratio, cure rate and so on were all improved. The results of the qualitative interviews showed: the TB patients and the doubts among prisoners could be well gotten together and isolated to receive DOTS; doctors were able to receive trainings on TB treatment and take appointment with certificate. Conclusion According to the results of qualitative interviews, the published and the secondary documents, it could be seen that DOTS are well implemented with remarkable effects.
ObjectiveTo systematically review the trend of tuberculosis among Chinese students. MethodsPubMed, Web of Science, EMbase, CBM, WanFang Data and CNKI databases were electronically searched to collect cross-sectional studies on the incidence and trend of tuberculosis among students in China from inception to August 2021. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; then, meta-analysis was performed by using Stata 15.0 software. ResultsA total of 97 cross-sectional studies were included. The results of meta-analysis showed that: the overall incidence of tuberculosis among students in China was 18.63 per 100 000 persons. The incidence in the northwest, south, northeast, north, east, central, and southwest 46.81, 11.22, 24.38, 12.77, 12.03, 18.95, and 39.26 per 100 000 persons, respectively. The incidence among university students, senior high school students, junior school students, and primary school students 38.17, 33.84, 8.85, and 1.68 per 100 000 persons, respectively. ConclusionCurrent evidence shows that the incidence of tuberculosis among students in China is high. Among them, the incidence rate of tuberculosis in the central and western regions, universities and high school students is relatively high.
