Despite scientific evidence originating from two patients published to date that CCR5Δ32/Δ32 hematopoietic stem cell transplantation (HSCT) can cure human immunodeficiency virus type 1 (HIV-1), the knowledge of immunological and virological correlates of cure is limited. Here we characterize a case of long-term HIV-1 remission of a 53-year-old male who was carefully monitored for more than 9 years after allogeneic CCR5Δ32/Δ32 HSCT performed for acute myeloid leukemia. Despite sporadic traces of HIV-1 DNA detected by droplet digital PCR and in situ hybridization assays in peripheral T cell subsets and tissue-derived samples, repeated ex vivo quantitative and in vivo outgrowth assays in humanized mice did not reveal replication-competent virus.

After the Berlin Patient, and the London Patient. There appears to be a third patient cured of HIV through stem cell transplantation.

The recipient of an allogeneic stem cell transplant from a CCR5Δ32/Δ32 donor shows evidence of HIV type 1 cure, including the absence of a viral rebound over 4 years after stopping antiretroviral treatment.
