Objective: To investigate the relationship between plasma heat shock proteins 90α(Hsp90α) levels and the white matter hyperintensity(WMH) in patients with cerebral small vessel disease(SVD). Methods: Patients admitted to the Department of Neurology, the First Affiliated Hospital of Zhengzhou University from March to August 2021 and diagnosed with WMH by magnetic resonance examination (MRI) were selected as the case group, matched with physical examination patients who visited the Department of Medical Examination during the same period and showed no WMH on MRI and no history of neurological diseases as the control group, and the level of plasma Hsp90α was quantitatively detected by enzyme-linked immunosorbent assay. Mann-Whitney U test was used to compare whether there was a difference in plasma Hsp90α levels between the control group and the case group.Multivariate logistic regression analysis was used to explore the related factors of WMH in patients with SVD. Results: Of the 183 subjects, the control group (n=73) consisted of 28 males and 45 females, aged (54±10) years, while the case group (n=110) consisted of 71 males and 39 females, aged (64±10) years old. Plasma Hsp90α level was higher in the case group than that of the control group [53.33(35.33, 70.09) ng/ml vs 35.02(18.51, 54.95) ng/ml, P<0.001]. After adjusting for confounding factors by multivariate analysis, the results showed that plasma Hsp90α levels greater than 58.34 ng/ml was associated with WMH (P=0.002, OR=5.931, 95%CI:1.955-17.995). Conclusion: Higher level of plasma Hsp90α is associated with WMH in patients with SVD.
