Researchers found that gut barrier dysfunction may increase the risk of skeletal-related events (SREs) in people living with HIV (PWH) who are on antiretroviral therapy (ART). Specifically, they discovered that higher levels of a biomarker called zonulin-1 were linked to a greater risk of SREs, but this was only true for individuals with lower immune function. For those with a CD4+ T-cell count below 500 cells/mm³, elevated zonulin-1 levels were associated with more than a fivefold increase in the risk of SREs.

This finding is particularly important for individuals with HIV who want to maintain their bone health as they age. Chronic inflammation and gut barrier dysfunction are known to contribute to various health issues, including bone fragility. By understanding the relationship between gut health and immune status, people can take steps to monitor their health more effectively. If you are living with HIV and have concerns about bone health, being aware of your immune status and discussing these findings with your healthcare provider could be crucial.

The research was conducted within the Spanish CoRIS cohort and involved a detailed analysis of plasma biomarkers in 65 individuals who experienced SREs and a larger group of 263 PWH. While the study provides valuable insights, it is still in the early stages. The results show a significant association between gut barrier dysfunction and SREs, but more research is needed to confirm these findings and explore potential interventions.

For those looking to improve their gut health and overall well-being, focusing on a balanced diet rich in fiber, probiotics, and nutrients may support gut integrity, though specific recommendations should be discussed with a healthcare professional.
