PG - 003981 LID - 10.12890/2023_003981 [doi] LID - 003981 AB - Long-acting (LA) cabotegravir/rilpivirine (CAB/RPV) is a complete regimen for the management of human immunodeficiency virus type 1 (HIV-1) infection to replace their oral antiretroviral therapy (ART) when they have been virologically suppressed. We present a case of successful achievement of undetectable HIV RNA viral load levels in an acquired immunodeficiency syndrome (AIDS) patient with long-standing virologic failure within two months of CAB/RPV LA initiation. This was later complicated by immune reconstitution inflammatory syndrome (IRIS) due to Mycobacterium avium-intracellulare (MAI) infection and hepatitis B virus (HBV) reactivation. LEARNING POINTS: This case highlights the efficacy of monthly CAB/RPV LA in rapidly reducing the HIV viral load level in a poorly controlled patient who lacked significant resistance to the two drugs.This is the first case of IRIS reported in the literature while using CAB/RPV LA. IRIS in the setting of occult MAI is well recognised. It would have occurred with good adherence to any regimen which rapidly suppressed the viral load and is unlikely to be due to CAB/RPV. CAB/RPV has no activity against HBV, which may have contributed to its reactivation.The patient had serologic evidence of resolution of prior HBV. However, some patients have covalently closed circular DNA (cccDNA) that may remain long term in hepatocyte nuclei. CI - (c) EFIM 2023.
