Going Beyond Giving Antiretroviral Therapy: Multimorbidity in Older People Aging with HIV in Nigeria

摘要

“Graying of HIV epidemic” is observed globally, as people living with HIV (PLWH) are aging, due to effectiveness of antiretrovirals. The normal aging processes and HIV-induced immune dysfunction, are potential mechanisms, driving multimorbidity (MM) in PLWH. MM is the concurrent presence of two or more diseases in a single individual. Aging PLWH, are at increased risk of acute and chronic morbidities compared with counterpart without HIV. Despite increasing concern in Nigeria, research on correlates of MM in aging PLWH is lagging. This was a comparative study, of ≥60 years of age, age-matched (±5 years) HIV-positive and HIV-negative patients. Patients were recruited, from the Infectious Disease Institute and Geriatric clinics of the University College Hospital, Ibadan, Nigeria, between April and June 2018. MM was defined as the occurrence of more than two morbidities in an individual, and it was considered acute, when within 30 days and chronic, when above 3-months duration. Data analysis was done using SPSS 23. We studied 186 individuals (62 HIV-positive and 124 HIV-negative). The PLWH had lower mean age (63.9 vs. 68.1 years, p?=?.00, t?=?5.68), more chronic MM (2.0 vs. 1.3, p?=?.004, t?=?2.970), which occurred earlier (4.7 vs. 9.6 years, p?=?.003, t?=?3.05), more overall MM (3.6 vs. 2.8, p?=?.015, t?=?2.448), and lower quality of life (82.7 vs. 86.2, p?=?.002, t?=?3.130). Risk estimates for “any” MM revealed the odds are in favor of the older PLWH [69.4% vs. 46.8%, p?=?.004, odds ratio?=?0.388 (95% confidence interval?=?0.204–0.740)]. Logistic regression revealed, age >64 years, higher total body fat, lower nadir CD4 counts, and longer duration of HIV infection, were significantly associated with MM in aging PLWH (p?=?.019). Older individuals with HIV on antiretrovirals in Ibadan, had a significantly greater burden of MM compared with those without HIV. HIV treatment programs in Nigeria will need to adapt a comprehensive health care plan for aging PLWH.
