Relationship of serum prealbumin level with the severity of acute ischemic stroke in 2522 patients

Abstract

Objective To assess the relationship of serum prealbumin level with the severity of acute ischemic stroke (AIS).Methods The clinical data of 2522 AIS patients who were admitted in Peking Union Medical College Hospital from 2000 to 2008 were retrospectively analyzed.The serum prealbumin and hypersensitive C-reactive protein (hs-CRP) levels were evaluated by immunoturbidimetric assay within 24 hours after admission.The AIS severity was evaluated at admission using modified Rankin Scale (mRS).Patients were divided into mild AIS group (mRS score ≤ 3 ) and severe AIS group (mRS score ＞ 3 ).The levels of serum prealbumin and hs-CRP were compared between these two groups,and the relationship between praalbumin and hs-CRP was also analyzed.Results There were 1697 patients in the mild group (average mRS score:1.67) and 825 patients in the severe group ( average mRS score:4.53 ).The severe group had significantly lower prealbumin level [ ( 191.20,82.00)versus (219.18,72.00) mg/L,P =0.000] and higher hs-CRP level [ (6.01,8.22) versus (4.15,6.93) mg/L,P =0.000 ] than the mild group,respectively.Partial regression analysis showed that the stroke severity was negatively correlated with serum prealbumin level (r =-0.115,P =0.000) and positively correlated with hs-CRP level (r =0.098,P =0.000).Serum prealbumin level was inversely correlated with hs-CRP level ( r =- 0.396,P =0.000).Conclusion The prealbumin level is relevant with the severity of AIS and inflammation.
