Blood glucose levels during the initial 72 h and 3-month functional outcomes in acute intracerebral hemorrhage: The SAMURAI-ICH study

Purpose: Prognostic values of blood glucose levels following admission remain unclear. We investigated associations between blood glucose levels during the initial 72 h and outcomes of acute ICH. Methods: Participants comprised hyperacute ICH patients who received intravenous antihypertensive treatment Blood glucose levels were measured on admission and at 24 and 72 h after starting treatment, along with hemoglobin (Hb)A1c level on admission. Associations with clinical outcomes of hematoma expansion (>33% increase), none to minimal disability (3-month modified Ranldn Scale [mRS] 0-1) and bedridden or death (3-month mRS 5-6) were analyzed. Results: Of the 176 patients (70 women; 65 +/- 12 years), 30 (18%) showed hematoma expansion, and 33 (19%) had none to minimal disability and 15 (10%) were bedridden or died. On multivariate regression analysis, blood glucose at 24 h (per 10 mg/dl odds ratio [OR], 0.84; 95% confidence interval [CI], 0.69-0.98) and blood glucose at 72 h (OR, 0.75; 95%CI, 0.59-0.92) were inversely associated with none to minimal disability, and blood glucose at 24 h (OR, 1.14; 95%CI, 1.00-1.30) was positively associated with bedridden or death. No parameters were associated with hematoma expansion. Conclusions: High blood glucose levels at 24 and 72 h were independently associated with poor functional outcomes 3 months after ICH. We need to investigate whether blood glucose control during the acute period ameliorates clinical outcomes. (C) 2015 Elsevier B.V. All rights reserved.
