Clinical Report: The Relationship of Betaine, Insulin Resistance, and Cognitive Decline
Overview
This study investigates the associations between metabolic markers and cognitive performance in individuals with and without HIV. Findings indicate that insulin resistance significantly impacts cognitive health in people with HIV, while higher levels of betaine are associated with better cognitive performance.
Background
Metabolic dysfunction and neurocognitive decline are critical issues, particularly in individuals with HIV, who may experience heightened vulnerability due to persistent immune activation and ART-related effects. This study aims to clarify how metabolic markers relate to cognitive outcomes in people with and without HIV.
Data Highlights
Metric
Findings
Mean Age
55.7 years
Higher GlycA in Diabetes
p = 0.001
DRI and Global T-scores
β = -0.27, p = 0.009
LP-IR in PWH
Interaction p = 0.007
Betaine and Global T-scores
β = 0.24, p = 0.02
Betaine and LP-IR in PWH
β = -0.47, p < 0.01
Key Findings
Higher DRI levels correlate with worse cognitive performance (β = -0.27, p = 0.009).
LP-IR is linked to cognitive performance in PWH but not in PWoH (interaction p = 0.007).
Betaine is associated with better cognitive performance in PWH (β = 0.24, p = 0.02).
Betaine levels correlate with lower LP-IR in PWH (β = -0.47, p < 0.01).
Higher GlycA levels are observed in individuals with diabetes (p = 0.001).
Clinical Implications
The findings indicate the importance of understanding the relationship between insulin resistance and cognitive health in individuals with HIV.
Conclusion
This study highlights the role of insulin resistance in cognitive health among individuals with HIV. Further research is needed to explore these associations.
