title: Acute leukocyte and temperature response in hypertensive intracerebral hemorrhage.
abstract: OBJECTIVE
  We undertook this study to investigate the relationship between outcome, hematoma volume, and admission peripheral white blood cell count and body temperature in acute hypertensive intracerebral hemorrhage.
  
  
  METHODS
  Eighty-two consecutive patients who presented with hypertensive intracerebral hemorrhage within 72 hours of onset were retrospectively assessed. The peripheral white blood cell count, polymorphonuclear leukocytes, and the body temperature on admission were measured. The outcome at 30 days after ictus was determined with a modified Glasgow Outcome Scale. Correlation analysis was performed between these measurements and hematoma volume, which was calculated by brain computed tomography. We also looked at the presence or absence of intraventricular extension.
  
  
  RESULTS
  The mean hematoma volume was significantly greater in those patients who died compared with those with a good, moderate, and severe outcome (79.6 cm3 versus 10.7, 18.3, and 19.9 cm3, respectively; P < .0005). The mean peripheral white blood cell count was higher in those who died than in the other three groups (12.580 +/- 0.521 versus 8.160 +/- 0.543, 8.565 +/- 0.543, and 7.427 +/- 0.786 x 10(9)/L, respectively; P < .0005). The mean body temperature of those who died tended to be higher than those in the good-outcome group (99.12 +/- 0.21 versus 98.18 +/- 0.21 degrees F, P < .05). A positive linear correlation was observed between hematoma volume and white blood cell count (r = .506, df = 77, P < .001), as well as the polymorphonuclear leukocyte count (r = .561, df = 76, P < .001). A trend was also observed for admission temperature (r = .265, df = 74, P < .05). The leukocyte response was enhanced by the presence of intraventricular extension.
  
  
  CONCLUSIONS
  There is a relationship between the size of the hematoma and the degree of leukocytosis in hypertensive intracerebral hemorrhage. This relationship appears to most likely represent a stress-induced reaction of the white blood cell count.
