Multidrug resistant tuberculosis (MDR-TB), is an emerging public health problem in sub-Saharan Africa (SSA). This study aims to determine the trends in prevalence of MDR-TB among new TB cases in sub-Saharan Africa over two decades.
We searched electronic data bases and accessed all prevalence studies of MDR-TB within SSA between 2007 and 2017. We determined pooled prevalence estimates using random effects models and determined trends using meta-regression.
Results: We identified 915 studies satisfying inclusion criteria. Cumulatively, studies reported on MDR-TB culture of 34,652 persons. The pooled prevalence of MDR-TB in new cases was 2.1% (95% CI; 1.7-2.5%). There was a non-significant decline in prevalence by 0.12% per year.
We found a low prevalence estimate of MDR-TB, and a slight temporal decline over the study period. There is a need for continuous MDR-TB surveillance among patients with TB.
耐多药结核病(MDR-TB)是撒哈拉以南非洲(SSA)一个新出现的公共卫生问题。本研究旨在确定二十多年来撒哈拉以南非洲新结核病病例中耐多药结核病的流行趋势。
我们检索了电子数据库,并获取了2007年至2017年期间撒哈拉以南非洲地区所有耐多药结核病的患病率研究。我们使用随机效应模型确定合并患病率估计值,并使用元回归确定趋势。
我们确定了915项符合纳入标准的研究。累计有34652人的耐多药结核病培养结果被报道。新病例中耐多药结核病的合并患病率为2.1%(95%CI;1.7-2.5%)。患病率每年下降0.12%,差异无统计学意义。
我们发现耐多药结核病的患病率估计值较低,且在研究期间略有下降。有必要对结核病患者进行持续的耐多药结核病监测。
