OBJECTIVE: The aim of this study was to quantify HIV-specific immunological and virological changes in people with HIV (PWH) on antiretroviral therapy (ART) with malignancy who received immune checkpoint blockade (ICB). DESIGN: An observational cohort study. METHODS: Blood samples were collected before and after four cycles of ICB in HIV-positive adults on ART. Virological assessments performed on CD4+ T cells included cell-associated unspliced HIV RNA, cell-associated HIV DNA, Tat/rev-induced limiting dilution assay (TILDA) and plasma HIV RNA using a single copy assay (SCA). Flow cytometry was used to assess the frequency of precursor exhausted T cells (Tpex) and exhausted T cells (Tex), an..
