Ferritin and OSA

Ferritin and Iron are affected by many things. It makes it difficult to study its relationship to OSA.

High and low ferritin levels were associated with increased risk https://www.tandfonline.com/doi/full/10.2147/NSS.S499446
Bio-marker for Severe OSA in obesity https://pdfs.semanticscholar.org/bdb5/565c3efbd91f8360781cd5adf2da00fac611.pdf
Bio-marker for Severe OSA in healthy https://pmc.ncbi.nlm.nih.gov/articles/PMC10047524/
Chronic Intermittent Hypoxia in OSA increases ferritin https://pmc.ncbi.nlm.nih.gov/articles/PMC10764456/
Some genes upregulated and helped reduce ferroptosis and oxidative stress after 1 year of CPAP use. These changes may not be epigenetic as it can just be a physiologic response to the use of the CPAP only. https://pmc.ncbi.nlm.nih.gov/articles/PMC10764456/

C-Reactive Proteins and OSA

C-reactive Proteins reduce after adenotonsilectomy.

Although with epigenetic orthodontic therapy, enlarged adenoids and tonsils may decrease spontaneously, this study shows the reduced OSA (from the tonsillectomy) reducing the CRP levels. https://www.sciencedirect.com/science/article/abs/pii/S0385814621001863

Other Bio-markers for OSA

Various Bio-markers tell us something is going on with our health.

For OSA, markers such as IL-6, C-reactive protein (CRP), and TNF-α, 8-isoprostane, Cysteine and Homocysteine are bio-markers. https://pmc.ncbi.nlm.nih.gov/articles/PMC3418859/
