Reye's syndrome. An epidemiologic analysis of mild disease
American Journal of Diseases of Children (1960)
|December 1, 1986
Summary
This study compared Reye's syndrome (RS) patients at stage 0 (alert) with those at stage 1 or greater. Laboratory findings like serum ammonia and bilirubin increased with RS severity, indicating disease progression.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Toxicology
Background:
- Reye's syndrome (RS) is a serious condition affecting children and adolescents.
- Accurate staging is crucial for understanding disease progression and patient outcomes.
Purpose of the Study:
- To compare demographic, clinical, and laboratory features of Reye's syndrome patients classified as stage 0 versus stage 1 or greater.
- To identify laboratory markers that correlate with Reye's syndrome severity.
Main Methods:
- Utilized the Centers for Disease Control case definition and staging criteria.
- Investigated 227 Reye's syndrome patients from Ohio Department of Health data (1978-1980).
- Compared 67 stage 0 patients with 160 patients classified as stage 1 or greater.
Main Results:
- Stage 0 and stage 1+ Reye's syndrome patients showed similarities in demographics, preceding illnesses, and medications.
- Liver function tests were comparable between the two severity groups.
- Serum ammonia, creatine phosphokinase, prothrombin time, and bilirubin levels significantly increased with Reye's syndrome severity (stage 1 or greater).
Conclusions:
- Early-stage Reye's syndrome (stage 0) shares characteristics with more severe stages.
- Specific laboratory values, including ammonia and bilirubin, serve as indicators of Reye's syndrome progression.
