The relationship between neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with obstructive sleep apnea syndrome

27220

Objective: There is a strong relationship between obstructive sleep apnea syndrome (OSAS) and cardiovascular disease (CVD). Chronic intermittent hypoxia, inflammation, oxidative stress, and endothelial dysfunction may create etiologic mechanisms, connection between OSAS to CVD. Inflammation play an important role in the development of CVD. Platelet- Lymphocyte Ratio (PLR) and Neutrophil-lymphocyte Ratio (NLR) are new biomarkers showing inflammation. This study was designed to investigate the association between PLR, NLR and relationship between severity of OSAS, polysomnographic parameters and PLR. Methods: This was a cohort study in which patients who had undergone a full night polysomnography for diagnosis of OSA were recruited. Patients were divided according to their apnea hypopnea index (AHI) scores into OSAS negative simple snoring (Group 1; AHI 5 times/hours), mild (Group 2; AHI: 5-15), moderate (Group 3; AHI:15-30), and severe OSAS (Group 4; AHI 30) groups. Results: A total of 111 patients were included in this study. There were 26, 22 and 63 patients in Groups 1, 2 and 3, respectively. PLR were significantly different between groups (Group 1: 87.12, Group 2: 103.6, Group 3: 112.5, p 0.05). PLR were significantly correlated with NLR, AHI, oxygen desaturation index, average and minimum O2 saturation values (p 0.05). Multiple regression analysis demonstrated that PLR is an independent predictor of CVD. PLR cut-off value for demonstrating the presence of CVD is higher than 86.03. Conclusion: In the light of these findings, PLR is strongly associated with the severity of OSAS. PLR might be used as a biomarker to predict CVD in OSAS patients.
