Aging and HIV: Recent Findings in Contributing Factors.

Background: Aging among people living with HIV (PLWH) presents multifaceted challenges influenced by antiretroviral therapy (ART), chronic inflammation, viral coinfections, stigma, multimorbidity, and immunosuppression. Methods: This review synthesizes recent research findings to outline factors contributing to aging with HIV. A comprehensive literature search was done using electronic databases including PubMed, Web of Science, Google Scholar, and CINAHL with keywords "HIV," "Aging," "Elderly," "Geriatrics," "Older Adults," "HIV Infections," and "HIV/AIDS. Results: Addressing age-related comorbidities, cognitive impairment, and non-AIDS events is imperative as older PLWH face increased morbidity and mortality rates compounded by coinfections such as HCV, HPV, TB, HSV, and bacterial infections. While ART is vital for viral suppression, it introduces challenges such as mitochondrial toxicity, metabolic disorders, and decreased CD4 cell counts, accelerating the aging process. Lifestyle factors, including smoking, substance abuse, malnutrition, sedentary behavior, and mental health conditions, further exacerbate aging in PLWH. Conclusions: This study emphasizes the necessity of holistic approaches to meet the unique healthcare needs of older PLWH, with insights into immunosenescence, coinfections, disease progression, ART exposure, and lifestyle factors. Understanding these dynamics is crucial for improving health outcomes and quality of life in aging PLWH.
