[HIV/TB co-infection in rural settings of benin: case of Djougou-Ouake-Copargo district (north-west Benin]. 
We measured the burden of HIV/tuberculosis (HIV/TB) co-infection in people infected by TB in rural settings of Benin, and assessed the outcome of TB treatment at the end of the intensive phase.  This is a retrospective, cross-sectional, descriptive study, covering January 2006 to December 2011.  A total of 256 patients were gathered, 67 (26.1%) were HIV +.  A proportion of 25% of co-infected HIV / PTB had TB bacilli high density (+++) versus 45% of mono-infected (P = 0.005).  The smear conversion was obtained in 96% of coinfected versus 93% in HIV- at the end of the intensive phase (P = 0.5).  The cure rate was 86% and 93.1% respectively in co-infected and HIV-.  A proportion of 13.5% of co-infected died versus 3% in HIV- (P = 0.005).  21% of co-infected with CD4 <200 died versus 3.6% of those with CD4> 200 (P = 0.041).  This work underlines the high prevalence of HIV / TB co-infection in this region.  Co-infected patients respond well to treatment, but their mortality is high when they are very immunocopromissed.
