AIM To investigate the association between alcohol use and adherence to Highly Active Antiretroviral Treatment (HAART) among HIV-infected patients in sub-Saharan Africa. DESIGN and MEASURES Cross sectional survey conducted in eight adult HIV treatment centers from Benin, Côte d’Ivoire and Mali. During a four-week period, health workers administered the Alcohol Use Disorders Identification Test to HAART-treated patients and assessed treatment adherence using the AIDS Clinical Trials Group follow-up questionnaire. RESULTS A total of 2920 patients were enrolled with a median age of 38 years (IQR 32–45 years) and a median duration on HAART of 3 years (IQR 1–4 years). Overall, 91.8% of patients were identified as adherent to HAART. Non-adherence was associated with current drinking (OR 1.4; 95% CI 1.1–2.0), hazardous drinking (OR 4.7; 95% CI 2.6–8.6) and was inversely associated with a history of counseling on adherence (OR 0.7; 95% CI 0.5–0.9). CONCLUSION Alcohol consumption and hazardous drinking is associated with non-adherence to HAART among HIV-infected patients from West Africa. thus providing a framework for developing and reinforcing the necessary prevention and intervention strategies.

The study aimed to estimate costs of provision and access to highly active antiretroviral therapy (HAART) in order to assist in planning and resource allocation regarding scaling up and sustainable access to HAART in Benin. A prospective study was carried out to collect data on costs of provision of care at the Outpatient Treatment Centre (OTC) of the National University hospital in Cotonou, Benin and on costs borne by people living with HIV/AIDS (PLWHA) and their families in accessing care. We used an Excel model, a macro costing approach and WHO guidelines for costing health services. Annual costs were subsequently extrapolated from a societal perspective over a 10-year time horizon. Sensitivity analysis was conducted on major cost categories. The study population was mostly of middle age (median age of 38, IQR 34-42), married (65%), working class (60%) with low literacy (70% primary education level or less). The main drivers of costs of HAART service provision were drugs (73%), biological monitoring (15%) and personnel (8%). Annual costs of provision of HAART and household costs borne by PLWHA and families in seeking care amounted to 1160 USD and 111 USD per PLWHA respectively. These household costs are respectively 40% and 14% of household health and education related costs and may represent catastrophic health expenditures for patients and families. The provision of drugs and biological monitoring, and household costs in accessing care, remain by far the main barriers to ensuring universal access to HAART.

Résumé Objectif Étudier entre 1996 et 2006, l’évolution des schémas thérapeutiques et du profil clinique et immunologique des patients infectés par le VIH au début du traitement antirétroviral (TARV) en Afrique de l’Ouest. Cadre et méthode Les données issues de 12 centres cliniques adultes (IeDEA West Africa réseau collaboratif de prise en charge de l’infection à VIH) de cinq pays (Bénin, Cote d’Ivoire, Sénégal, Gambie, Mali) ont été mises en commun et analysées. Les patients âgés de 16 ans et plus dont le sexe, la date de naissance et la date d’initiation du TARV étaient connus ont été inclus dans cette étude. Résultats Quatorze mille quatre-cent-quatre-vingt-seize patients avaient débuté un TARV entre 1996–2006 avec 55 % des patients l’ayant débuté entre 2005–2006. La proportion de femmes était de 46 % en 1996–2000 et de 63 % en 2005–2006. L’âge médian à la mise sous traitement était constant: 35 ans chez les femmes et 40 ans chez les hommes. La proportion de patients qui ont débuté le TARV avec un taux de CD4 inférieur à 200 cellules/µl était de 54 % en 1996–2000 et de 64 % en 2005–2006. Les combinaisons thérapeutiques les plus prescrites étaient: AZT/3TC (ou d4T/DDI)/IDV (27 %) en 1996–2000; d4T (ou AZT)/3TC/EFV (59 %) en 2003–2004; et d4T/3TC/NVP (49 %) en 2005–2006. Les traitements de première ligne recommandés par l’OMS étaient débutés dans 83 % de cas en 2005–2006. Conclusion De nouvelles approches pour débuter un TARV plus précocement doivent être développées pour améliorer la survie des patients sous TARV.

Background The incidence and risk factors for lipodystrophy and metabolic disorders among patients in Africa on first-line combined antiretroviral treatment (cART) mostly containing non-nucleoside reverse transcriptase inhibitors is poorly documented. Methods This prospective cohort study recruited 88 HIV-infected patients initiating cART between October 2004 and June 2005 in Cotonou, Benin. Patients were followed for 24 months. The main outcomes were incidence of lipodystrophy and metabolic disorders. Multivariate Cox proportional hazards regression models were used to describe factors associated with progression to lipodystrophy. Results After a median follow-up of 23.2 months (interquartile range 22.3–23.7), 24 (30%) patients developed lipodystrophy (lipoatrophy 9%, lipohypertrophy 24% and mixed pattern 2.5%). The incidence rate for lipodystrophy was estimated to 1.72 per person-month (95% confidence interval [CI] 1.15–2.56) occurring after a median time of 11 months on cART. Metabolic syndrome (International Diabetes Federation definition) appeared in 10 (13%) patients after a median of 15 months with an estimated incidence rate of 0.62 per person-month (95% CI 0.33–1.16). It was more common in women (19.2% versus 3.1% in men; P=0.043). Diabetes (8%) and hypercholesterolaemia (35%) were also observed. After adjustment, gender, young age (hazard ratio [HR] 0.45 [95% CI 0.22–0.90]; P=0.025), high BMI at inclusion (HR 1.53 [95% CI 1.28–1.83]; P<0.0001) and smoking (HR 28.0 [95% CI 2.5–307.4]; P=0.006) were significantly associated with lipohypertrophy. Conclusions Lipodystrophy and metabolic syndrome were commonly and rapidly observed in this cohort of sub-Saharan patients initiating cART.
