ABSTRACT
Objective To explore the changes of serum lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) and the level of lipids in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).Methods A total of 94 candidates with sleep disorders between January-July 2011 at outpatient department were monitored with polysomnography.According to apnea-hypopnea index (AHI),they were divided into mild-to-moderate OSAHS (5 ≤ AHI ≤ 30) (n =27),severe OSAHS (AHI > 30) (n =37) and normal control groups (AHI < 5) (n =30).After polysomnography,their blood samples were obtained to measure the levels of serum LOX-1,triglycerides (TG),cholesterol (TC),high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C).Results The serum level of LOX-1 in severe OSAHS group was significantly higher than that in the mild-to-moderate and control groups (P < 0.01).The serum level of LOX-1 in OSAHS patients was positively correlated with AHI and longest apnea time (LAT)(r =0.645 & 0.501 respectively,both P < 0.01) and was negatively correlated with SaO2 (r =-0.647,P <0.01).No significant difference existed in serum lipids in all groups (P > 0.05).Conclusions Intermittent hypoxia caused by OSAHS increases the level of LOX-1 to further promote the formation and development of atherosclerotic in patients with OSAHS.The levels of lipid can not effectively predict the severity of lipid metabolism disorder in patients with OSAHS.
