Insights
Men with HIV on highly active antiretroviral therapy (HAART) experience more neurologic disorders at younger ages than HIV-negative men. This study highlights increased risks for infections, dementia, seizures, and peripheral nerve issues.
Area of Science:
- Neurology
- Infectious Diseases
- Public Health
Background:
- The advent of highly active antiretroviral therapy (HAART) has transformed HIV management.
- Understanding the long-term impact of HIV on the nervous system in the HAART era is crucial.
Purpose of the Study:
- To investigate the incidence and patterns of neurologic disorders in HIV-positive men compared to HIV-negative men.
- To analyze these differences within the context of HAART treatment.
Main Methods:
- A prospective study of men who have sex with men (MSM) was conducted.
- Comparison of neurologic diagnoses incidence and categories between HIV-positive and HIV-negative participants during the HAART era (1996-2011).
Main Results:
- HIV-positive men on HAART developed neurologic diagnoses at a significantly younger median age (48 years) than HIV-negative men (57 years).
- Higher incidence rates of neurologic disorders were observed across all age groups in HIV-positive men.
- Specific conditions like nervous system infections, dementia, seizures/epilepsy, and peripheral nervous system disorders were more prevalent in the HIV-positive group.
Conclusions:
- HIV-positive men on HAART exhibit a greater burden of neurologic disease compared to their HIV-negative counterparts.
- Neurologic conditions manifest at earlier ages in HIV-positive individuals undergoing HAART.
- These findings underscore the need for continued surveillance and management of neurologic complications in the HIV-positive population.
Objective:
To study the incidence and pattern of neurologic disorders in a large cohort of HIV-positive men, compared with HIV-negative men, in the era of highly active antiretroviral therapy (HAART).
Methods:
The Multicenter AIDS Cohort Study is a prospective study of men who have sex with men enrolled in 4 cities in the United States. We compared HIV-positive vs HIV-negative men for incidence and category of neurologic diagnoses in the HAART era (July 1, 1996, to last known follow-up or death, on or before July 1, 2011).
Results:
There were 3,945 participants alive during the HAART era (2,083 HIV negative, 1,776 HIV positive, and 86 who became infected with HIV during the study period) including 3,427 who were older than 40 years of age. Median age at first neurologic diagnosis among all participants alive in the HAART era was lower in HAART-treated HIV-positive vs HIV-negative men (48 vs 57 years of age, p < 0.001). Incidence of neurologic diagnoses was higher in HAART-treated HIV-positive vs HIV-negative men (younger than 40 years: 11.4 vs 0 diagnoses per 1,000 person-years [p < 0.001]; 40-49 years: 11.6 vs 2.0 [p < 0.001]; 50-60 years: 15.1 vs 3.0 [p < 0.001]; older than 60 years: 17.0 vs 5.7 [p < 0.01]). Excess neurologic disease was found in the categories of nervous system infections (p < 0.001), dementia (p < 0.001), seizures/epilepsy (p < 0.01), and peripheral nervous system disorders (p < 0.001), but not stroke (p = 0.60).
Conclusions:
HIV-positive men receiving HAART have a higher burden of neurologic disease than HIV-negative men and develop neurologic disease at younger ages.
