|Abstract:||Female sex workers (FSW) remain highly affected by HIV and play a critical roleinits spread towards the general population, however, antiretroviral treatment coverage in this group still remains very low in west and central African countries. In line with the UNAIDS recommendations extending antiretroviral treatment to all HIV-infected individuals regardless their CD4 count, we carried out this demonstration project of early HIV treatment as prevention (TasP) aiming to assess the acceptability, feasibility, and utility of adding this strategy to the current prevention and treatment packageamong FSW in Cotonou, Benin. While assessing both acceptability and feasibility, we focused on treatment response including CD4 count restoration, adherence to treatment and viral suppression, and emergence of drug resistance. The study included 107 FSW who were followed between 12 and 24 months. At the end of the follow-up 64 remained in the study giving a retention rate of 59.8%. CD4 count recovery above 500 cells/μl was reached in more than 70% of participants. The geometric mean viral load decreased from 12372 copies/ml at baseline, to 105.1 copies/ml (<.0001) at 12 months; 95.1 copies/ml (p <.0001) at 24 months and 187.3 copies/ml at all final visits (p = 0.003). In addition, both suppressed (<1000 copies/ml) and undetectable (<40 copies/ml) viral loads were strongly associated with increasing levels of adherence to treatment (p for trend =0.048 and 0.004 respectively). Resistance mutations were detected in several participants at baseline, but none of those who had a final visit showed clinical resistance. Given the mobility in this group of population, efforts on retention and adherence to treatment, and regional collaboration between FSW-dedicated clinics could facilitate the implementation and positive impact of early treatment as prevention in this population.|
