Girls with HIV expertise accelerated DNA ageing, examine exhibits

Girls with HIV expertise accelerated DNA ageing, a phenomenon that may result in poor bodily operate, in line with a examine led by Stephanie Shiau, an assistant professor within the Division of Biostatistics and Epidemiology on the Rutgers College of Public Well being.

Printed in The Journal of Infectious Illnesses, the examine sheds mild on the distinctive challenges confronted by ladies with HIV as they age and opens avenues for tailor-made interventions to boost well being outcomes. Globally, over 50 p.c of people residing with HIV are ladies, and ladies accounted for an estimated 46 p.c of all new infections in 2022.

Girls with HIV expertise greater charges of bone loss in comparison with ladies with out the virus, which may place them at elevated danger of fracture as they age, in line with outcomes from the Girls’s Interagency HIV Examine.

Understanding the molecular mechanisms behind accelerated ageing in individuals with HIV is essential for creating focused interventions and bettering the standard of life for these residing with the virus.”

Shiau mentioned whereas accelerated ageing has been reported in individuals with HIV, these research have been primarily performed amongst males and never ladies.

The examine targeted on a pattern of 195 ladies with HIV ages 40 to 60, evaluating them to a cohort of ladies with out the virus, and performed varied analyses to discover how markers of ageing measured in blood had been associated to bone mineral density and measurements of bodily operate, comparable to muscle energy, strolling velocity, stability and endurance.

Girls with HIV had been ageing sooner than their chronological age, in line with the examine findings.

In each teams, ladies who could not maintain a single leg stand for 30 seconds displayed elevated ageing, suggesting potential hyperlinks between accelerated ageing and sure points of bodily operate and emphasizing the necessity for additional analysis to verify and comprehend these associations over time.

“The work demonstrates that girls residing with HIV expertise an accelerated ageing course of on the DNA degree, and that this ageing course of could also be linked to purposeful outcomes,” mentioned Shiau. “Future research might want to see whether or not these findings are noticed longitudinally.”

The analysis not solely contributes insights into the challenges confronted by ladies with HIV however supplies a foundation for additional examination of long-term outcomes for these residing with the virus.

Co-authors of the examine embrace researchers from collaborating establishments in New York, Illinois and California.
