Résumé
HIV cure has been reported for five individuals who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) with cells from CCR5Δ32 homozygous donors. By contrast, viral rebound has occurred in other people living with HIV who interrupted antiretroviral treatment after undergoing allo-HSCT, with cells mostly from wild-type CCR5 donors. Here we report the case of a male individual who has achieved durable HIV remission following allo-HSCT with cells from an unrelated HLA-matched (9 of 10 matching for HLA-A, HLA-B, HLA-C, HLA-DRB1 and HLA-DQB1 alleles) wild-type CCR5 donor to treat an extramedullary myeloid tumor. To date, plasma viral load has remained undetectable for 32 months after the interruption of antiretroviral treatment. Treatment with ruxolitinib has been maintained during this period to treat chronic graft-versus-host disease. Low levels of proviral DNA were detected sporadically after allo-HSCT, including defective but not intact HIV DNA. No virus could be amplified in cultures of CD4 <sup>+</sup> T cells obtained after antiretroviral treatment interruption, while CD4 <sup>+</sup> T cells remained susceptible to HIV-1 infection in vitro. Declines in HIV antibodies and undetectable HIV-specific T cell responses further corroborate the absence of viral rebound after antiretroviral treatment interruption. These results suggest that HIV remission could be achieved in the context of allo-HSCT with wild-type CCR5.
