Background: Cataracts contribute 12% of visual loss among HIV-infected adults (HIV-positive) in Uganda. Immuno-pathogenesis of cataracts may differ among HIV-negative and HIV-positive individuals; thus the need for innovative therapeutic interventions for cataracts among HIV-positive adults. We compared the regulatory T-cell (Treg) dysfunction among HIV-positive-with-cataracts, HIV-negative-with-cataracts and respectively age-matched HIV-healthy-volunteers.
Methods: In a laboratory based case-control study, nested within a clinical/surgical community outreach camp, within the Rakai Health Sciences Program (RHSP) rural cohort, 50 adults with cataracts eligible for surgery were selected consecutively. Routine provider-initiated HIV testing was done for individuals with unknown HIV sero-status. Peripheral Blood Mononuclear Cells (PBMC) were colle.. View More»
