Abstract | ||||
Background: Obstructive sleep apnea (OSA) and obesity lead to a hypoxic state, increasing the hypoxia-inducible factor 1-alpha (HIF1-α) level to achieve cellular adaptation. Objectives: To clarify the correlation between HIF 1-α level with both OSA severity and obesity. Patients and methods: A case-control study was conducted on patients attending the sleep disorders unit at South Valley University Hospital from March 2022 to July 2023. 64 patients were diagnosed by a standard nocturnal polysomnography (PSG). A blood sample was taken to detect HIF 1-α level. Results: Considering the HIF 1-α level, our study disclosed no significant difference between controls and OSA patients (P = 0.92), while there was a statistically considerable difference between different OSA groups (P = 0.001). Also, there are statistically significant positive correlations between HIF 1-α serum level with all of the following, AHI (r = 0.381, P = 0.008), the number of desaturation index (ODI) (r = 0.51, P < 0.001). and waist circumference (WC) (r = 0.291, P = 0.045). Conclusion: OSA severity is associated with an increase in HIF-1α levels and neck and waist circumference reinforces the role of obesity and fat distribution in OSA pathophysiology. | ||||
