Reye
Area of Science:
- Pediatrics
- Neurology
- Hepatology
Background:
- Reye's syndrome in infants is not well-defined or frequently diagnosed.
- Infants under six months with a viral illness may rapidly develop Reye's syndrome.
Observation:
- Eight infants under six months experienced lethargy, seizures, and coma after a viral illness.
- Abnormal liver function tests, including high blood ammonia, were noted in all patients.
- Pathological studies confirmed fatty visceral infiltration in three infants.
Findings:
- Prominent clinical findings in infantile Reye's syndrome include significant respiratory issues (tachypnea, apnea), early-stage seizures, and frequent hypoglycemia.
- A socioeconomic bias was observed, with affected infants primarily from lower socioeconomic, urban backgrounds.
- This contrasts with older children with Reye's syndrome, who are typically middle-class and from suburban/rural areas.
Implications:
- This study highlights key clinical features and demographic patterns of Reye's syndrome in infants.
- Understanding these characteristics is crucial for early diagnosis and management of this rare condition.
- Further research may elucidate the underlying mechanisms and contributing factors, especially the observed socioeconomic disparities.
Abstract:
Reye's syndrome in infancy is not a well-defined entity and is infrequently diagnosed. Eight infants 6 months of age or younger had a prodromal viral illness followed by the rapid onset of lethargy, seizures, and coma, resulting in the diagnosis of Reye's syndrome. All had abnormal results of liver function tests including elevations of blood ammonia level. Three patients had pathological studies that confirmed fatty visceral infiltration. The data on these patients, as well as a review of the literature, indicate that the most prominent clinical findings in Reye's syndrome in infancy include marked respiratory abnormalities with tachypnea and apneic episodes; frequent occurrence of seizures in the early stages of the illness; and hypoglycemia in most cases. A strong socioeconomic bias was noted in these patients, with the infants coming primarily from lower socioeconomic, urban environments, while older children with Reye's syndrome have been observed to be predominantly middle-class and from suburban or rural areas.
