    Abstract:
    Although the adverse effect of admission hyperglycemia in cerebral infarction on prognosis is well known, studies generally have not questioned the effect of hyperglycemia in the early subacute period on prognosis after a stroke. Forty-six patients with acute ischemic stroke were seperated into 3 groups: Group 1) Known diabetes or admission blood glucose (ABG) > or = 140 mg/dl and HbA1c > or = 8,0%); Group 2) ABG > or = 140 mg/dl and HbA1c < 8,0%; and Group 3) ABG < 140 mg/dl and HbA1c < 8,0%. Blood glucose was followed-up 4 times a day for 10 days after the stroke and the mean of these measurements was calculated as the mean of glycemic regulation (MGR). Neurological evaluation was done at presentation and on day 10 and 30 with the National Institute of Health (NIH) scale. Oedema, lesion size and presence of hemorrhagic transformation were evaluated using CT. The MGR was significantly higher in group 1 compared to the other two groups (p < 0,001 and p < 0,01) and in group 2 compared to group 3 (p < 0,001). Patients with clinical worsening had a significantly higher MGR (p < 0,05). Patients with marked cerebral edema had a significantly higher MGR (p < 0,01) compared to patients with lesser edema. No correlation was found between MGR and lesion size or hemorrhagic transformation. Our results show that hyperglycemia in the early subacute period after cerebral infarction is associated with more pronounced cerebral edema and has an adverse effect on short term prognosis. We suggest that studies investigating the effect of insulin infusion on stroke prognosis should also consider infusions for a longer period than 24 hours.
