  1. The pathogenesis of Reye syndrome, while not precisely elucidated, appears to involve mitochondrial injury resulting in dysfunction that disrupts oxidative phosphorylation and fatty-acid..
  2. The initial acid-base status of eight survivors of Reye's syndrome was characterized by acute respiratory alkalosis (Pco2=32 mm Hg; Hco3-=22.0 mEq/liter) while that of eight children who died was associated with metabolic acidosis as well (HCO3-=10.0 mEg/liter)
  3. Reye syndrome is a rare and potentially fatal pediatric illness defined as acute noninflammatory encephalopathy with fatty liver failure. Australian pathologist R.D.K. Reye first described this syndrome in 1963. National surveillance of Reye syndrome began in the United States in the early 1970s and led to strict warnings regarding aspirin use in.

Reye's syndrome most often affects children and teenagers recovering from a viral infection, most commonly the flu or chickenpox. Signs and symptoms such as confusion, seizures and loss of consciousness require emergency treatment

Disease has almost disappeared in children as aspirin use has declined for viral-like illnesses Reye syndrome, acute neurologic disease that develops primarily in children following influenza, chicken pox, or other viral infections. It may result in accumulation of fat in the liver and swelling of the brain. The disease was first reported by the Australian pathologist R.D.K. Reye in 1963 The pathophysiology of Reye's syndrome appears as follows: The pathogenesis of Reye's syndrome, while not precisely elucidated, appears to involve mitochondrial injury resulting in dysfunction that inhibits oxidative phosphorylation and fatty-acid beta-oxidation in a virus-infected, sensitized host

Reye's syndrome is a rare but serious condition that results in microvesicular hepatitic steatosis (fatty changes of the liver) and acute encephalopathy (altered mental status) primarily in children and teenagers recovering from a viral illness (such as influenza or varicella zoster virus) Reye's syndrome (RS) is primarily a children's disease, although it can occur at any age. It affects all organs of the body but is most harmful to the brain and the liver--causing an acute increase of pressure within the brain and, often, massive accumulations of fat in the liver and other organs. RS is defined as a two-phase illness because it. Reye syndrome is a rare form of acute encephalopathy and fatty infiltration of the liver that tends to occur after some acute viral infections, particularly when salicylates are used. Diagnosis is clinical. Treatment is supportive Reye's syndrome is defined by the Centers for Disease Control and Prevention as an acute, noninflammatory encephalopathy associated with altered levels of consciousness and liver dysfunction. Reye's syndrome occurs in all ages, seasons, and geographical locations, but it usually affects young children

Abstract Children with Reye's Syndrome were found to have low levels of serum selenium. Two drugs associated with Reye's Syndrome, aspirin and valproic acid, decreased serum and hepatic levels of selenium in animals. A chemical (4-pentenoic acid) previously used to produce an animal model of Reye's Syndrome, was also found to alter selenium status Reye's syndrome is usually treated in the hospital. Severe cases may be treated in the intensive care unit. The hospital staff will closely monitor your child's blood pressure and other vital signs. Specific treatment may include: Intravenous fluids. Glucose and an electrolyte solution may be given through an intravenous (IV) line
