| Popis: | BACKGROUND: Gradient-echo T2*-weighted magnetic resonance imaging (T2*-weighted MRI) is highly sensitive for detecting cerebral microbleeds (CMBs). CMBs have been reported to be a risk factor for future cerebrovascular events and a marker of cerebral small vessel disease in the general population. Chronic kidney disease (CKD) is an independent risk factor for cardiovascular disease. The relationship between CKD and CMBs, which has not been clarified to date, is examined. METHODS: In this cross-sectional study, T2*-weighted MRI of brain was performed with a 1.5-T MRI system in 162 CKD patients (CKD stages 1-5, excluding CKD stage 5(D)) and 24 normal subjects. RESULTS: CMBs were found in 35 CKD patients (25.6%), but not in control subjects. CMBs were more prevalent in male patients, in those with higher blood pressure, advanced age and poor kidney function. There was a significant association between the prevalence of CMBs and the CKD stage, with higher prevalence of CMBs as the CKD stages advanced (P < 0.01). Estimated glomerular filtration rate was a significant factor associated with the prevalence of CMBs, independent of age, gender and hypertension. There was no significant relationship between CMBs and the presence of diabetes mellitus and dyslipidemia. CONCLUSIONS: Decreased renal function is a significant risk factor for CMBs, independent of the presence of hypertension. Poor kidney function could be associated with future cerebrovascular events. |
