Özet

Background: The novel molecule endocan, which is released by endothelium and is regulated by proangiogenic and proinflammatory cytokines, may have a role in the pathophysiology of Alzheimer disease (AD). The aim of this study was to evaluate the relationship between serum endocan levels and AD. Methods: A total of 134 patients (47 AD, 42 amnestic mild cognitive impairment [aMCI], and 45 control patients) 65 years of age and older were recruited in this study. Cognitive status of the patients was evaluated by performing the Montreal Cognitive Assessment (MOCA) and the Mini-Mental State Examination (MMSE). Serum endocan levels were measured with an enzyme-linked immunosorbent assay kit. Results: Median serum endocan level was significantly higher in AD patients (380.1 ng/mL) than in both aMCI patients (247.7 ng/mL) and controls (277.6 ng/mL; p < 0.01). Serum endocan level had a weak but significant correlation with MMSE and MOCA scores (r = -0.219 and r = -0.232; p = 0.012 and p = 0.01, respectively). Serum endocan level was detected as a factor independently associated with AD. The cutoff serum level of endocan predicting AD was > 288.94 ng/mL in receiver operating characteristic curve analysis (area under the curve 0.71, 95% CI 66.7-90.9, sensitivity 80.9%, specificity 59.8%; p < 0.01). Conclusion: Higher serum endocan levels may be associated with the pathogenesis of AD. (c) 2018 S. Karger AG, Basel
