abstract = {Increasing evidence supports the role of cardiovascular
risk factors in the development of Alzheimer’s disease
(AD).Objective:In the present pilot study, we investigated
plasma concentrations of myeloperoxidase (MPO) and its
possible association with plasma amyloid-β (Aβ)1-42/1-40
ratio in AD patients and elderly healthy
controls.Methods:The study sample included 28 AD patients
and 27 elderly individuals with a normal cognitive status as
a control group. The Mini-Mental Status Examination was used
to determine the global cognition. MPO, Aβ1-40, and Aβ1-42
plasma concentrations were measured by enzyme linked
immunoabsorbent assays.Results:AD patients showed
significantly higher plasma concentrations of MPO in
comparison to healthy elderly controls (AD versus healthy
elderly controls (mean ± SD): 132.8 ± 114.8 ng/mL versus
55.0 ± 42.6 ng/mL; p = 0.002). MPO plasma concentrations
showed a significant positive correlation in the whole
sample with the presence of AD (ρ = 0.428, p < 0.001) and
its stage (ρ = 0.331; p = 0.013) as well as with plasma
concentrations of Aβ1-42 (ρ = 0.406; p = 0.004) and
Aβ1-42/1-40 ratio (ρ = 0.354; p = 0.013). In a binary
logistic regression model, plasma MPO concentrations were
independently associated with the presence of AD (p =
0.014).Conclusion:AD patients showed significantly increased
plasma levels of MPO, which could be an important molecular
link between atherosclerosis and AD. Further studies should
evaluate whether MPO may also be a useful biomarker and
potential new treatment target in AD.},
