Abstract
The association between Alzheimer’s disease and uric acid levels had gained great interest in recent years, but there was still lack of definite evidence. A systematic review and meta-analysis of relevant studies was performed to comprehensively estimate the association. Relevant studies published before October 26, 2014, were searched in PubMed, Embase, and China Biology Medicine (CBM) databases. Study-specific data were combined using random-effects or fixed-effects models of meta-analysis according to between-study heterogeneity. Twenty-four studies (21 case-control and 3 cohort studies) were finally included into the meta-analysis. Those 21 case-control studies included a total of 1128 cases of Alzheimer’s disease and 2498 controls without Alzheimer’s disease. Those 3 cohort studies included a total of 7327 participants. Meta-analysis showed that patients with Alzheimer’s disease had lower levels of uric acid than healthy controls (weighted mean difference (WMD) = −0.77 mg/dl, 95 % CI −2.28 to −0.36, P = 0.0002). High serum uric acid levels were significantly associated with decreased risk of Alzheimer’s disease (risk ratio (RR) = 0.66, 95 % CI 0.52–0.85, P = 0.001). There was low risk of publication bias in the meta-analysis. There is an inverse association between serum uric acid levels and Alzheimer’s disease. High serum uric acid level is a protective factor of Alzheimer’s disease.
