title: Determinants of survival in AIDS patients on antiretroviral therapy in a rural centre in the Far-North Province, Cameroon.
abstract: OBJECTIVE
  To analyse the outcomes of antiretroviral therapy (ART) in routine conditions in a rural hospital in the Far-North province of Cameroon.
  
  
  METHODS
  Retrospective cohort study of 1187 patients >15 years who started ART between July 2001 and December 2006. The survival time was estimated by Kaplan-Meier analysis and Cox proportional hazard models were fitted to explain survival.
  
  
  RESULTS
  Upon enrollment, 90.4% patients were in WHO stage III or IV and 56.1% had a BMI <18.5. Median CD4 count was 105 cells/mm(3) (IQR 40-173). At the end of the study period, 338/1187 had died and 59/1187 were lost to follow-up. The survival probability was 77% at 1 year [95% CI: 75-80] and 47% at 5 years [95% CI: 40-55]. The median survival time was 58 months. CD4 count, haemoglobin, BMI, sex and clinical stage at enrollment were independent predictors of mortality.
  
  
  CONCLUSIONS
  This study confirms the clinical benefit of ART programs in a remote and resource-constrained setting operating in routine conditions. The challenge ahead is to secure earlier access to ART and to maintain its longer-term benefit.
