A 10-year survey on prevalence and occurrence rate of multi-drug resistant Mycobacterium tuberculosis in Latin American and Mediterranean Families: A Systematic review and meta-analysis

Latin American and Mediterranean (LAM) is a family of Mycobacterium tuberculosis (M. tuberculosis). Drug resistant in M. tuberculosis LAM family is a major problem in the world population. Our objective of this study was to determine the prevalence of M. tuberculosis LAM family with multi-drug resistant (MDR) in the worldwide by a meta-analysis and systematic review.

Data sources of this study were 68 original articles (2001-2012) which were published in different databases. Research articles with full text in English were selected. Review articles, congress abstracts, studies that were reported in languages other than English and also studies that were not available for us in abstract or full text were excluded. Data that were obtained from prevalence and occurrence rate of MDR M. tuberculosis LAM family were analyzed using meta-analysis random effects models with software package Meta R, Version 2.13 (P < 0.10).

During 10 years, lowest rate of prevalence was observed in 2010 and 2006 (95% CI: 5.91%-6.95%) and highest prevalence rate was in 2006 (95% CI: 17.48%- 24.05%). prevalence of MDR- M. tuberculosis analysis showed positive MDR between them (95% CI: 10.30%-11.23%). Prevalence for negative MDR was 9.22% (95% CI: 8.3%- 10.2%).

Our study showed that M. tuberculosis LAM family is prevalent in Europian countries. LAM sub lineage was a major focus of studies that carried out in different countries. The proper technique for prevention of transmission of M. tuberculosis is necessary.
