ObjectiveTo overview the systematic reviews on the timing of different surgical interventions for severe multidrug-resistant pulmonary tuberculosis patients.MethodsPubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases were searched for systematic reviews about the timing of different surgical interventions for severe multidrug-resistant pulmonary tuberculosis patients from inception to December, 2018. Two reviewers independently screened literature, extracted data, evaluated the reporting and methodological qualities using the PRISMA checklist and the AMSTAR tool. After re-extraction of individual RCT data from included systematic reviews, meta-analysis was performed by Stata10.0 software.ResultsA total of 11 systematic reviews were included. The average methodological quality score was 8.13 in AMSTAR , the reporting quality score was from 19.5 to 25 in PRISMA. Re-performed meta-analysis showed that, the total success rate of operation was 93.3% (95%CI 92.9 to 93.8), the failure rate was 3.7% (95%CI 3.3 to 4.0), the mortality rate was 2.0% (95%CI 1.8 to 2.2), and the loss rate was 1.0% (95%CI 0.8 to 1.2). The cure rates of different surgical methods were all over 80%, among which single lobectomy (98.47%) and compound lobectomy (98.94%) had the higher cure rates than others. For the time of different surgical interventions, cure rate could be improved obviously in patients receiving surgery treatment after 1 months (OR=1.58, 95%CI 1.29 to 1.94, P=0.000 12), 1-8months (OR=1.66, 95%CI 1.30 to 2.12, P=0.000 05) and 9-24 months (OR=1.48, 95%CI 1.15 to 1.90, P=0.002) of anti-tuberculosis therapy compared with 0 month.There were significant differences between two groups.ConclusionCurrent evidence shows that operation is an effective way for severe multidrug-resistant pulmonary tuberculosis. Operative opportunity should be selected after 1-24 months of anti-tuberculosis drug treatment when the operation time depending on whether the tuberculosis has turned negative or not. Operative mode should be decided by the location and the scope of the lesion, which ensures the maximum excision of lesions and retention of lung function.
ObjectiveTo systematically review the unfavorable treatment outcome of multidrug-resistant tuberculosis in China. MethodsCNKI, WanFang Data, CBM, PubMed, EMbase, and Web of Science databases were electronically searched to collect studies that reported unfavorable treatment outcomes of multidrug-resistant tuberculosis in China from inception to April 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed by using Stata 12.0 software. ResultsA total of 11 studies involving 4 465 patients were included. The results of meta-analysis showed that the overall rate of treatment success was 62% (95%CI 55% to 70%), the rate of treatment failure was 19% (95%CI 12% to 26%), the rate of default was 7% (95%CI 4% to 10%), the rate of mortality was 6% (95%CI 4% to 8%) and the rate of unfavorable treatment outcome was 25% (95%CI 19% to 32%). ConclusionsCurrent evidence shows that the treatment failure rate of multidrug-resistant tuberculosis in China is slightly high. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
Objective To systematically review the treatment outcomes of multidrug-resistant tuberculosis (MDR-TB) patients, and to provide evidence for treatment. Methods Databases including PubMed, Web of Science, ScienceDirect, CNKI, WanFang Data and VIP were electronically searched to collect literature related to MDR-TB from inception to April 28th, 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using R 4.0.5 software, subgroup and meta-regression analyses were performed based on sample size, survey time, etc. Results A total of 36 studies involving 7 981 patients were included. The results of meta-analysis showed that the overall treatment success rate of MDR-TB patients was 60% (95%CI 56% to 63%). The subgroup analysis showed that the treatment success rates of MDR-TB were 49% (95%CI 41% to 58%) from 1992 to 2010, 62% (95%CI 58% to 65%) from 2011 to 2015, and 62% (95%CI 55% to 68%) from 2016 to 2020; those with sample size above 100 and less than 100 were 60% (95%CI 55% to 65%) and 59% (95%CI 54% to 63%), respectively; those with average age above 45 and less than 45 were 58% (95%CI 51% to 65%) and 56% (95%CI 53% to 59%); those of MDR-TB were 63% (95%CI 57% to 68%) in central China, 63% (95%CI 52% to 73%) in the Northwest, 60% (95%CI 55% to 65%) in the Southeast, and 53% (95%CI 48% to 58%) in the Northeast. Conclusions The overall success rate of treatment for MDR-TB patients in China is low. Due to the limited quantity and quality of included studies, more high-quality studies are required to verify the above conclusions.
