Non-antiretroviral drugs uses among HIV-infected persons receiving antiretroviral therapy in Senegal: Costs and factors associated with prescription

In addition to antiretroviral therapy, non-antiretroviral drugs are necessary for the appropriate care of people living with HIV. The costs of such drugs are totally or partially supported by the people living with HIV. We aimed to evaluate the overall costs, the costs supported by the people living with HIV and factors associated with the prescription of non-antiretroviral drugs in people living with HIV on antiretroviral therapy in Senegal. METHODS: We conducted a retrospective cohort study on 331 people living with HIV who initiated antiretroviral therapy between 2009 and 2011 and followed until March 2012. The costs of non-antiretroviral drugs were those of the national pharmacy for essential drugs; otherwise they were the lowest costs in the private pharmacies. Associated factors were identified through a logistic regression model. RESULTS: The study population was 61 % female. At baseline, 39 % of patients were classified at WHO clinical stage 3 and 40 % at WHO clinical stage 4. Median age, body mass index and CD4 cells count were 41 years, 18kg/m2 and 93 cells/?L, respectively. After a mean duration of 11.4 months of antiretroviral therapy, 85 % of patients received at least one prescription for a non-antiretroviral drug. Over the entire study period, the most frequently prescribed non-antiretroviral drugs were cotrimoxazole (78.9 % of patients), iron (33.2 %), vitamins (21.1 %) and antibiotics (19.6 %). The mean cost per patient was 34 Euros and the mean cost supported per patient was 14 Euros. The most expensive drugs per treated patient were antihypertensives (168 Euros), anti-ulcer agents (12 Euros), vitamins (8.5 Euros) and antihistamines (7 Euros). The prescription for a non-antiretroviral drug was associated with advanced clinical stage (WHO clinical stage 3/4 versus stage 1/2): OR=2.25; 95 % CI=1.11-4.57 and viral type (HIV-2 versus HIV-1/HIV-1+HIV-2): OR=0.36; 95 % CI=0.14-0.89. CONCLUSION: Non-antiretroviral drugs are frequently prescribed to people living with HIV in developing countries; mainly those infected with HIV-1 and those at an advanced clinical stage. Their costs can be a barrier to appropriate care and necessary efforts must made to make them available. However, early initiation of antiretroviral therapy and the registration of some non-antiretroviral drugs on the list of essential drugs, as well as social protection systems, should reduce their use and costs
