abstract = {The association between F2-isoprostanes and Alzheimer's
disease (AD) has been controversially discussed in the
literature since the 1990s. However, no systematic review
has been performed so far.A systematic review of
observational studies on the associations of F2-isoprostanes
and the specific biomarker 8-iso-prostaglandin F2α with AD
were conducted. Random-effects model meta-analyses were
performed.29 studies were included in the systematic review,
including four longitudinal studies. In an overall
meta-analysis of the 25 cross-sectional studies,
F2-isoprostane levels were statistically significantly
associated with AD (Hedge's g $[95\%$ confidence interval]:
1.00 [0.69-1.32]). When studies were grouped by biomarker
and sample specimen, F2-isoprostane and 8-iso-prostaglandin
F2α levels were statistically significantly elevated in
tissue samples of the frontal lobe of AD patients. Moreover,
F2-isoprostane levels in cerebrospinal fluid and
8-iso-prostaglandin F2α levels in blood samples of AD
patients were significantly increased. Meta-analyses of the
few longitudinal studies did not reach statistical
significance.Increased concentrations of F2-isoprostanes
were found in AD patients. However, due to the lack of
adjustment in most cross-sectional case-control studies,
results must be interpreted carefully. In addition, the
causality of the association is uncertain because evidence
from well-conducted longitudinal studies was conflicting,
and further longitudinal studies are required to reinforce
the results.},
