Can Monocyte to HDL Ratio be a new Marker for Severity of Obstructive Sleep Apnea Syndrome?

Abstract

Background: This study aimed to investigate the relation of serum monocyte to serum HDL cholesterol ratio (MHR) with obstructive sleep apnea syndrome (OSAS). A total of 62 patients with an apnea hypopnea index (AHI > 5) and excessive daytime sleepiness were included in this study as OSAS group. The individuals with (AHI) < 5/h were included in the study as controls. OSAS patients were compared with the control group for high density lipoprotein (HDL) levels, serum monocyte count, and monocyte to HDL ratio (MHR). Mild, moderate and severe OSAS subgroups were compared for the same parameters. Results: MHR was 11.93 ± 6.52 in the control group while it was 14.87 ± 6.98 in OSAS group, with a statistically significant difference in between them (p= 0.016). The MHR were positively correlated with AHI and the minimum oxygen saturation (p = 0.003 and p = 0.012, respectively). Conclusion: serum monocyte to serum HDL cholesterol ratio increased as OSAS severity increased. MHR is an easy and available biomarker. It can be used as a new marker for severity of OSAS
