dc.description.abstractEnBACKGROUND: People living with HIV-2 are mainly found in West Africa and their identification and treatment have been impaired by diagnostic challenges and availability of effective antiretroviral treatment (ART). With the roll out of first line dolutegravir (DTG)-based regimen, the situation may have improved, emphasizing the need for data on long-term treatment outcomes and advanced HIV disease among ART-experienced people living with HIV-2. METHOD: A prospective cohort was initiated in 2012 in Côte d'Ivoire and Burkina Faso. All adult patients from Côte d'Ivoire with an undetectable viral load, were included and followed up. HIV-2 viral load and CD4 counts were done during the routine follow-up visits and a detailed clinical assessment was done during the last follow up visit of the year 2018 corresponding to the censor date of the cohort. Outcomes were described as follow: in care (known alive and present during the last ART follow up visit), loss to follow-up (absent for more than 90 days and not reported dead), and dead (reported dead with a date of event). Advanced HIV disease followed WHO definition and virologic failure was define as viral load > 50 copies/mm3. The Kaplan-Meier curve was used to estimate mortality and Loss to follow-up probability. RESULTS: Among the 108 HIV-2 patients in virologic success in 2012, 95 agreed to participate and were enrolled in the "success cohort". Their median age was 53 [47-60] years and all of them were receiving boosted-lopinavir-based ART regimen. Of the 95 participants, 65 (68.4%) remained in care, 20 (21.1%) were loss to follow-up and 10 (10.5%) were reported dead. The survival analysis retrieved a decreasing probability of remaining alive and in care over the time, moving from 90% to 80.7% and to 73.0% after 24, 48 and 72 months respectively. Overall, 36 (37.9%) patients presented with advanced HIV disease at their last visit, higher among those dead/ loss to follow-up compared to those remaining in care (60.0% vs 27.7%; p-0.003). CONCLUSION: High advanced HIV disease rate was found in HIV-2 patients, six years after an initial virologic success. This emphasizes the need to enable the one-stop-shop model that allow an early management of opportunistic infections while integrating non-communicable diseases services in HIV-2 care.
