Are microbleeds in ischemic stroke associated with lower serum adiponectin and higher soluble E-selectin levels? Context: Cerebral microbleeds (CMBs) are the important indicators of cerebral small vessel disease. However, it is still unclear whether endothelial dysfunction is involved in CMBs. In this study, we performed a prospective study to investigate the correlation between sE-selectin (soluble E-selectin) or adiponectin and the prevalence of CMBs. We recruited 133 consecutive patients with first-ever ischemic stroke for this study. Finally, 126 patients were analyzed. The number and presence of CMBs were detected and evaluated on susceptibility-weighted magnetic resonance imaging within two weeks after symptom onset. We assessed the serum levels of adiponectin and sE-selectin for patients. CMBs were detected in 63 subjects (50%) within 126 patients and more prevalent in mixed brain regions (55.6%). In binary logistic regression analysis, each 1SD-increase in adiponectin level was significantly conversely associated with the prevalence of CMBs after adjusting for age, sex and cardiovascular risk factors (OR = 0.55; 95% CI: 0.36-0.84); but sE-selectin was significantly positively associated with the prevalence of CMBs (OR = 1.09; 95% CI: 1.02-1.15). Furthermore, partial correlation analyses showed that sE-selectin remained significantly associated with and correlated conversely to adiponectin (r = -0.452, p = 0.001).

Endothelial injury may play a role in the pathogenesis of CMBs, and serum levels of adiponectin and sE-selectin were closely related to CMBs. Adiponectin might be protective for the prevalence of CMBs. Final Decision: yes
