an idiopathic condition associated with asprin treatment during certain viral infections
Reye syndrome The cause of Reye syndrome is unknown.[2] It usually begins shortly after recovery from a viral infection, such as influenza or chickenpox.[1] About 90% of cases are associated with aspirin (salicylate) use in children.[2] Inborn errors of metabolism are also a risk factor.[3] Changes on blood tests may include a high blood ammonia level, low blood sugar level, and prolonged prothrombin time.[2] Often the liver is enlarged.[2]
