Background: The S147G mutation is associated with high-level resistance to the integrase strand transfer inhibitor (INSTI) elvitegravir. In several poorly documented cases, it was also selected in patients on dolutegravir. Given the widespread use of dolutegravir, further studies of S147G are required.

We report that, despite an initial efficacy of a LEN-containing regimen in patients with multi-drug resistant HIV-2 viruses, virological suppression was not achieved after a year and most patients selected capsid drug-resistance associated mutations.

They are recommended as first- or second-line (FL and SL) options in two- and three-drug regimens (2DR and 3DR) in international treatment guidelines. However, there are limited real-world data on emerging resistance at the time of virological failure (VF) with these regimens.
