Abstract:
Objective To investigate serum levels of lipoprotein-associated phospholipase A2 (Lp-PLA2),high-sensitivity C-reactive protein (hs-CRP),complement component C1q (C1q) and homocysteine(HCY) in patients with Alzheimer's disease(AD),in order to provide a basis for establishing laboratory markers in AD patients.Methods One hundred AD patients and one hundred healthy controls from Beijing Hospital were selected.Serum levels of Lp-PLA2,C1q,hs-CRP and HCY were determined using a biochemistry analyzer.Serum levels of amyloid β-protein 40(Aβ40)and Aβ42 were measured using enzyme-linked immunosorbent assays.Results Serum levels of Aβ40,Aβ42,Lp-PLA2,hs-CRP,C1 q and HCY were higher in AD patients than in the control group[(66.0±14.0) pmol/L vs.(7.1±8.2) pmol/L,(7.2±1.4) pmol/L vs.(1.9±1.7) pmol/L,(510.6±140.1)U/L vs.(419.0±91.8) U/L,(2.8±3.4) mg/L vs.(1.2±0.7) mg/L,(218.0±58.4) mg/L vs.(194.8 ± 27.7) mg/L and (18.8 ± 9.3) μmol/L vs.(14.9 ± 5.2) μmol/L,all P ＜ 0.01],and the differences were greater in female subjects than in male subjectss.Conclusions High serum levels of Lp-PLA2,C1q,hs-CRP and HCY may be associated with Alzheimer's disease,while the exact relationships need to be further investigated.
