AbstractBackgroundThe association between subclinical CMV replication and HIV persistence has not been investigated in cis-gender women with HIV.MethodsFifty virologically suppressed female participants with HIV were prospectively enrolled and provided oral, vaginal, urine samples and peripheral blood mononuclear cells (PBMCs) at one cross-sectional time-point. Cytomegalovirus (CMV) DNA was quantified in each specimen by real-time PCR. Cellular HIV DNA and HIV RNA transcripts (unspliced and multiply spliced [ms] encoding tat-rev) were quantified by droplet digital (dd)PCR. Historical data from 49 male individuals with HIV and CMV were used as controls.ResultsLevels of cellular HIV DNA and unspliced HIV RNA were not different between sexes, but female participants had less detectable msHIV RNA and CMV DNA compared to males (both P<0.01). Unlike previously described for males, the presence of CMV DNA was not associated with increased HIV DNA in females. Among female participants, pre-menopausal status was independently associated with lower HIV DNA compared to post-menopause, after adjusting for nadir CD4 count (P<0.01).ConclusionsFemale participants with HIV have reduced cellular HIV RNA and less subclinical CMV DNA compared to males, but overall similar HIV DNA levels in our study. Post-menopausal status was independently associated with higher HIV DNA levels among female participants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
