Objective To investigate the relationship between biomarkers of renal function and cerebral microbleeds (CMBs) in cerebral hemorrhage patients.Methods This is a cross-sectional study including a total of 129 patients with cerebral hemorrhage.All patients underwent susceptibility weighted 3.0 T MRI.The presence and number of CMBs on susceptibility weighted MRI were independently interpreted.We calculated the urinary albumin/creatinine ratio (UACR) from morning spot urine and the estimated glomerular filtration rate (eGFR) in serum samples.Serum cystatin C (CysC) was measured using the automated particle-enhanced turbidimetric immunoassay.Results Among 129 patients with cerebral hemorrhage,86 (66.7%) had CMBs on susceptibility-weighted imaging.UACR (mg/g;20.47 ± 9.03 vs 35.24±14.83,t=3.823,P<0.01)andCysC (mg/L;0.98±0.09vs 1.31 ±0.13,t=4.739,P<0.01) levels were higher in the patients with CMBs than those without,and the eGFR (ml · min-1 · 1.73 m 2) was lower in the patients with CMBs than those without (78.07 ± 18.69 vs 61.59 ± 17.08,t =3.672,P <0.01).A Logistic regression analysis indicated that the levels of kidney impairment biomarkers were significantly associated with the prevalence of CMBs in cerebral hemorrhage patients after an adjustment for age,sex and other risk factors.The odds ratio (OR) and 95% CI of each kidney biomarkers (eGFR,UACR,and CysC) for the CMBs status were 2.573 (1.172-5.315),2.735 (1.247-6.246)and 2.976 (1.764-6.968),respectively.CysC exhibited fair diagnostic value for CMBs,with an area under the curve of 0.835 (95% CI 0.791-0.878).Furthermore,there were negative correlations between eGFR and the the number of CMBs (P =0.038,R2 total =0.216).There was a positive correlation between UACR,CysC and number of CMBs (P =0.024,R2 total =0.312;P =0.013,R2 total =0.375).Conclusions Elevated levels of kidney biomarkers are associated with the presence of CMBs in cerebral hemorrhage patients,independent of conventional risk factors.CysC may be a potential diagnostic biomarker for CMBs in cerebral hemorrhage patients.

Diabetes mellitus is an independent predictor of high platelet reactivity after antiplatelet therapy in patients with ischemic stroke,and the latter is closely related to the increased risk of recurrence of stroke.The mechanisms of high platelet reactivity in patients with diabetes or insulin resistance are associated with a variety of factors.Some circulating molecules can be used as markers for predicting the reactivity of platelets.Monitoring of platelet reactivity after treatment with new antiplatelet agents may provide basis for individualized antithrombotic therapy in ischemic stroke patients with diabetes or insulin resistance.
