HIV integrase strand transfer inhibitors (INSTI) are considered well tolerated with few treatment-limiting adverse effects. However, emerging data from clinical trials has identified excessive weight gain possibly due to INSTI alone or with tenofovir alafenamide as a new and possible long-term complication of combination antiretroviral therapy (cART). Identifying who is at greatest risk and whether the unintended weight gain is reversible remain unanswered questions. We report a return to baseline weight after switching back to tenofovir disoproxil/emtricitabine/efavirenz (Atripla®) in a woman who had profound weight gain due to tenofovir alafenamide/emtricitabine/cobicistat/elvitegravir (Genvoya®).
