Abstract

Mitochondrial DNA (mtDNA) haplogroup has been associated with disease risk and longevity. Among persons with HIV (PWH), mtDNA haplogroup has been associated with AIDS progression, neuropathy, cognitive impairment, and gait speed decline. We sought to determine whether haplogroup is associated with frailty and its components among older PWH. A cross-sectional analysis was performed of AIDS Clinical Trials Group A5322 (HAILO) participants with available genome-wide genotype and frailty assessments. Multivariable logistic regression models adjusted for age, gender, education, smoking, hepatitis C, and prior use of didanosine/stavudine. Among 634 participants, 81% were male, 49% non-Hispanic white, 31% non-Hispanic black, and 20% Hispanic. Mean age was 51.0 (standard deviation 7.5) years and median nadir CD4 count was 212 (interquartile range 72, 324) cells/μL; 6% were frail, 7% had slow gait, and 21% weak grip. H haplogroup participants were more likely to be frail/prefrail (p = .064), have slow gait (p = .09), or weak grip (p = .017) compared with non-H haplogroup participants (not all comparisons reached statistical significance). In adjusted analyses, PWH with haplogroup H had a greater odds of being frail versus nonfrail [odds ratio (OR) 4.0 (95% confidence interval 1.0-15.4)] and having weak grip [OR 2.1 (1.1, 4.1)], but not slow gait [OR 1.6 (0.5, 5.0)] compared with non-H haplogroup. Among black and Hispanic participants, haplogroup was not significantly associated with frailty, grip, or gait. Among antiretroviral therapy (ART)-treated PWH, mtDNA haplogroup H was independently associated with weak grip and frailty. This association could represent a mechanism of weakness and frailty in the setting of HIV and ART.
