OBJECTIVE: Although HIV RNA can be suppressed with antiretroviral therapy (ART), chronic inflammation may persist in people living with HIV (PLWH). Because a low CD4+/CD8+ ratio is associated with morbidity and mortality, this study aimed to evaluate factors associated with CD4+/CD8+ ratio normalization, defined as a CD4+/CD8+ ratio ≥1.
MATERIALS AND METHODS: This retrospective cohort study included PLWH aged ≥18 years who were diagnosed between 2010 and 2017 and achieved viral suppression within the first year after starting ART. Data were retrospectively obtained from a tertiary care infectious diseases clinic.
RESULTS: Among 217 patients who received ART for at least 5 years, 187 (86.2%) had a CD4+ T-cell count >500 cells/μL at year 5, and 87 (40.1%) achieved a CD4+/CD8+ ratio ≥1. In multivariable logistic regression, higher baseline CD4+ T-cell count and a higher baseline CD4+/CD8+ ratio were independently associated with CD4+/CD8+ ratio normalization.
CONCLUSION: Including immunological markers alongside viral suppression may better reflect treatment success. Baseline immunological status appears to be associated with long-term CD4+/CD8+ ratio normalization in PLWH receiving suppressive ART. Monitoring these markers may help inform long-term follow-up strategies.
