BACKGROUND: The effects of the estimated glomerular filtration rate (eGFR) and cystatin C on clinical outcomes on intracerebral hemorrhage (ICH) remain unclear. We investigated the associations of eGFR and cystatin C with 3-month functional outcome and all-cause mortality in acute ICH patients. METHODS: A total of 365 patients with acute ICH were enrolled. Serum creatinine and cystatin C levels were measured within 24 h of admission. Outcomes at 3-month were evaluated by interviews with patients or their family members. Poor functional outcome was defined as a modified Rankin Scale score ≥3. RESULTS: During the 3-month follow-up, 154 patients experienced poor functional outcome, and 48 patients died from all causes. Low eGFR level was associated with poor outcome (adjusted OR 8.95; 95% CI 2.13-37.66; p-trend = 0.045) and all-cause mortality (adjusted hazards ratio (HR) 5.10; 95% CI 2.00-13.03; p-trend = 0.001). Additionally, a high cystatin C level was also found to be associated with all-cause mortality (adjusted HR 4.01; 95% CI 1.09-14.72; p-trend = 0.015). However, no significant association between cystatin C and poor functional outcome was observed (p-trend = 0.615). CONCLUSIONS: Low eGFR at baseline predicts poor functional outcome and all-cause mortality at 3-month in acute ICH patients. Also, high cystatin C was associated with increased risk of mortality but not with poor functional outcome.
