Özet
AimsIn obstructive sleep apnea (OSA), the balance between inflammatory and anti-inflammatory responses is disrupted. This study examined the association between serum angiotensin 1 (Ang 1), angiotensin 1-7 (Ang 1-7), and Mas receptor levels and OSA severity. Material and methodsA total of 190 subjects underwent polysomnography and serum analysis for Ang 1, Ang 1-7, and Mas using ELISA. Patients were classified into control, mild, moderate, and severe OSA groups based on AHI. ResultsAng 1-7, Ang 1, and serum Mas levels were significantly lower in moderate and severe OSA groups compared to control and mild OSA (p < 0.001). Negative correlations were found between these biomarkers and AHI (e.g. Ang 1-7: R = -0.597, p < 0.001). ROC analysis showed strong diagnostic performance: AUC was 0.864 for Ang 1-7, 0.873 for Ang 1, and 0.837 for Mas, with sensitivity of 98%, 98%, and 97%, respectively. ConclusionReduced levels of Ang 1-7, Ang 1, and Mas are associated with increased OSA severity. These biomarkers demonstrated high diagnostic value and may be useful in stratifying patients with moderate-to-severe OSA.
