Serum pancreatic enzymes in patients with coma due to head injury or acute stroke.
Serum amylase and lipase were measured in 32 patients with cerebral ischemia, 19 with spontaneous cerebral hemorrhage, 15 with head injury and intracranial bleeding, and 22 with head injury without intracranial bleeding; 20 healthy subjects were also studied as controls. Serum pancreatic isoamylase concentrations were assayed in hyperamylasemic sera. The overall incidence of hyperamylasemia was 14% (12 of 88 patients: 4 with cerebral ischemia, 4 with spontaneous cerebral hemorrhage, 1 with head injury and intracranial bleeding, and 3 with head injury without intracranial bleeding). In 4 of the 12 patients the hyperamylasemia was of pancreatic origin: 1 patient with cerebral ischemia, 1 patient with spontaneous cerebral hemorrhage, 1 patient with head injury and intracranial bleeding, and 1 patient with head injury without intracranial bleeding. The incidence of hyperlipasemia was 7% (6 of the 88 patients: 1 patient with cerebral ischemia, 2 with spontaneous cerebral hemorrhage, and 3 with head injury without intracranial bleeding). We conclude that hyperamylasemia is more frequent than hyperlipasemia in patients with an altered state of consciousness due to head injury or stroke and is usually of non-pancreatic origin. This knowledge may save these patients from invasive and costly examinations.
