Reye syn·drome

(rī),

an acquired encephalopathy of young children that follows an acute febrile illness, usually influenza or varicella infection; characterized by recurrent vomiting, agitation, and lethargy, which may lead to coma with intracranial hypertension; ammonia and serum transaminase levels are elevated; death may result from edema of the brain and resulting cerebral herniation. May be linked to aspirin ingestion.

Reye syndrome

Neurology A potentially fatal condition characterized by acute encephalopathy and fatty degeneration of liver, with a dose-dependent relationship to use of aspirin in children with viral infections–eg, influenza, varicella-zoster Clinical Vomiting, hepatic dysfunction, variable neurologic impairment–irritable and combative behavior, loss of consciousness, stupor, seizures, coma, death, often preceded by viral URIs or varicella Lab ↑ Transaminases, glutamine and ammonia in CSF, hypoglycemia, metabolic acidosis DiffDx Drug & chemicals–Aspirin, other salicylates, acetaminophen, lead, valproic acid, methyl bromide, hydrocarbons, chlordane, ethanol, disulfiram Infectious–viral encephalitis, hepatitis Metabolic–cystic fibrosis, carnitine deficiency, hereditary fructose intolerance, isovaleric acidemia, urea cycle disorders Others–Pancreatic encephalopathy, acute encephalopathy with fatty metamorphosis of the liver due to cold agglutinin autoimmune hemolytic anemia, toxic encephalopathy Treatment None universally accepted.

The clinical symptoms of the patients infected with NII561-2000-related viruses were gastroenteritis, respiratory symptoms, rash, and flaccid paralysis in addition to Reye syndrome (Table 5), and these disease categories were similar to those of other HPeVs (2,3).

In this study, we isolated a novel HPeV (NII561-2000) from a 1-year-old girl with Reye syndrome and determined the nucleotide sequence.

The NII561-2000 virus was originally isolated from a patient with Reye syndrome, an acute noninflammatory encephalopathy characterized by an antecedent viral infection, such as influenza or varicella (10-12).

Reye syndrome patients and controls, selected from the same school classroom or neighborhood and matched for age, sex, race, and the occurrence of a similar antecedent illness (respiratory, varicella, or gastrointestinal) within 1 week of that which occurred in the case, were interviewed concerning medications taken between the time of onset of the antecedent illness and either admission to the hospital for Reye syndrome (for cases) or recovery from the illness (for controls).

The recently reported study from Michigan involved 25 patients with Reye syndrome and 44 controls selected in a manner similar to that of the Ohio study, matched for the same criteria, and interviewed 4 to 83 days (mean 6.

Editorial Note: Although the epidemiologic association between Reye syndrome and antecedent viral illnesses is well established, the etiology of this rare disease remains unclear.

The Ohio and Michigan studies reported here and the previously reported smaller study from Arizona (involving 7 cases and 16 controls) are the only controlled studies of the relationship between Reye syndrome and medications taken during the antecedent illness reported since this disease was first described.

These include 1) difficulties in obtaining comparable and accurate medication histories in patients following a significant event (Reye syndrome) when compared to controls who have had a relatively minor illness, and the difficulty of accurate recall of events several weeks later, 2) the possibility that cases had a more severe antecedent illness and/or a pre-encephalopathic illness that included severe vomiting and headaches -- both of which may have predisposed them to take more medications than controls -- and 3) the presumed need to select cases and controls with the same viral infections, including influenza B, influenza A (H1N1), and varicella, since Reye syndrome is thought to be more strongly associated with these infections.
