A HIV Superinfection Diagnosed in a Patient on Intramuscular Long-acting Combination of Cabotegravir and Rilpivirine

Abstract A case of a male with human immunodeficiency virus with plasma genotyping detecting no resistance and a CRF02AG subtype had a controlled HIV RNA on antiretroviral therapy since 2010. We introduced intramuscular therapy with cabotegravir and rilpivirine. One month later, his HIV RNA was 1500 copies/mL; genotyping found a subtype B with many mutations.
