Reye's syndrome: clinical progression and evaluation of therapy.
The hospital course and therapy of 369 patients with Reye's syndrome were evaluated. Eighty-three percent of patients had deepening coma during hospitalization. Stage of coma on admission, evidence of increased intracranial pressure, and blood ammonia levels greater than 300 microgram/100 ml were all significantly associated with increasing mortality. Among survivors of Reye's syndrome, 30% of those who developed either decerebrate posturing or seizures during hospitalization had serious neurologic sequelae upon discharge. When analyzed by (1) stage of coma during admission (2) progression of coma during hospitalization, (3) degree of blood ammonia level elevation, and (4) presence of increased intracranial pressuring, no significant differences were noted between patients receiving intensive supportive care and those receiving exchange transfusions and/or peritoneal dialysis.
