Study Links Obstructive Sleep Apnea to Increased Oxidative Stress

A new study reveals that obstructive sleep apnea syndrome (OSAS) may cause increased levels of oxidative stress biomarkers such as lactate and vitamin E. Genetic data analysis shows a modest increase in lactate levels with OSAS, indicated by an odds ratio (OR) of 1.06 in initial findings and 1.16 in multivariable analysis. Conversely, lower levels of superoxide dismutase and matrix metalloproteinase 9 are also associated with OSAS, suggesting these biomarkers might contribute to the disease. The research implies that oxidative stress could both result from and contribute to OSAS, potentially due to disrupted glucose metabolism and heightened antioxidant responses to stress. Further studies with a broader range of markers are needed to confirm these findings.

This discovery underscores a closer connection between OSAS and oxidative stress than previously recognized, highlighting the need for comprehensive research on this link.
