Overview
Reye's syndrome is a rare but severe disorder characterized by encephalopathy and fatty degeneration of the liver, often triggered by viral infections in children and, rarely, adults, frequently associated with aspirin use 134.Diagnosis
Clinical Presentation: Encephalopathy, elevated liver enzymes, and fatty infiltration of the liver 15.
Associated Conditions: Viral infections (e.g., influenza, Epstein-Barr virus, dengue), especially in the context of aspirin exposure 146.
Laboratory Tests: Elevated liver function tests, ammonia levels, and coagulation profile abnormalities 16.
Imaging: Cerebral edema may be evident on neuroimaging 1.
Differential Diagnosis: Other causes of acute liver failure and encephalopathy, excluding those clearly linked to aspirin use 5.Management
Supportive Care: Intensive care monitoring, management of cerebral edema, and supportive measures for multiorgan dysfunction 1.
Avoid Aspirin: Strict prohibition of aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs) in affected individuals 2.
Specific Treatments: No specific pharmacological treatment; focus on supportive therapies including nutritional support and management of complications like DIC 16.Special Populations
Pediatrics: Majority of cases occur in children and adolescents; high vigilance for multiorgan involvement, especially post-viral infections 15.
Adults: Rare but reported cases associated with viral infections (e.g., dengue, influenza) suggest similar vigilance 34.
Comorbidities: No specific recommendations noted for comorbidities; focus remains on supportive care and avoiding triggers like aspirin 16.Key Recommendations
Avoid Aspirin in Children and Adolescents with Viral Infections: Do not administer aspirin to children and adolescents with viral illnesses to prevent Reye's syndrome development (Evidence: Strong 2).
Prompt Recognition and Supportive Care: Early recognition of Reye's syndrome and initiation of intensive supportive care, including management of cerebral edema and multiorgan dysfunction, is crucial (Evidence: Moderate 16).
Monitor for Multiorgan Involvement: Especially in pediatric cases following viral infections like Epstein-Barr virus or influenza, monitor for signs of multiorgan dysfunction (Evidence: Expert opinion 1).References
