Clinical Studies of the Inflammatory Markers in Patients with Obstructive Sleep Apnea-Hypopnea Syndrom Complicated by Cerebral Infarction / 现代检验医学杂志

ABSTRACT

Objective To investigate the change of homocysteine (Hcy),high sensitive C-reactive protein (hs-CRP)and Inter-leukin 6 (IL-6)in patients with Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS)complicated by Cerebral Infarction (CI).Methods Chose 55 patients with OSAHS and 56 patients with CI.All patients with OSAHS were divided into mild group,moderate group and severe group by polysomnography,and all patients were divided into simple OSAHS group,sim-ple CI group and OSAHS complicated by CI group.All the patients’sleep apnea hypoventilation index (AHI),the lowest oxygen saturation (LSpO2 ),average blood oxygen saturation (MSpO2 ),sleep apnea the longest (LAT)and the level of Hcy,hs-CRP,IL-6 were determined,and compared with 30 cases of control group.Results The AHI,LAT,Hcy,hs-CRP and IL-6 of simple OSAHS group and simple CI group were obviously higher than that in control group,LSpO2 ,MSpO2 were obviously lower,the differences were statistical significant (P<0.05).The AHI,LAT,Hcy,hs-CRP and IL-6 of OS-AHS complicated by CI group were obviously higher than that in simple groups,but LSpO2 and MSpO2 were obviously low-er,and the differences were statistical significant (P<0.05).With the aggravation of OSAHS,Hcy,hs-CRP and IL-6 were gradually increased.Hcy,hs-CRP and IL-6 were positively correlated with AHI in patients with OSAHS,correlation coeffi-cient were 0.751,0.678 and 0.635,respectively (P<0.001).Conclusion OSAHS was closely related to the occurrence and development of CI,the dynamic monitoring of Hcy,hs-CRP and IL-6 levels has a certain reference value for evaluation of therapeutic effect.
