In an ART interruption study of 2 PLWH who underwent HSCT for hematologic malignancies from CCR5 wild-type donors and had undetectable HIV RNA for years post-transplant while on ART, both participants developed detectable viremia after ART interruption: patient A at day 84 and patient B at day 225 (149). This evidence concerns the gene CCR5 and hematologic disorder.
