A five-month-old infant with Reye's syndrome developed disseminated intravascular coagulation, which was successfully controlled by heparin. A fatal outcome could not, however, be averted. The pathogenetic role of disseminated intravascular coagulation in Reye's syndrome is discussed.

Coagulation studies were performed on 13 children with clinical diagnoses of Reye syndrome. Four had abnormalities so severe that transfusion of coagulation factors and platelets were required prior to percutaneous liver biopsy. In one of these, abnormalities frequently found in association with acute hepatic failure were present. Disseminated intravascular coagulation was noted in two, while in the fourth child laboratory data were most consistent with that process. Although the coagulation defect associated with Reye syndrome is most often due to decreased production of all coagulation factors except VIII, these patients demonstrate that consumption can also occur. The severity of the coagulopathies found indicates that bleeding can become a major complication in the diagnosis and management of Reye syndrome.

Between July 1983 and February 1984, eight children with adenovirus Type 3 infection, proven by virus isolation from sputum, stool or nasopharyngeal swabs and a fourfold increase in complement fixation antibody titers against the virus, were treated in our department. All eight patients had fever lasting at least 7 days, hepatomegaly, diffuse pulmonary infiltrates and abnormal liver function tests. Seven of the patients exhibited dyspnea and pulmonary wheezing. Six of the patients developed changes in state of consciousness, and three had repeated convulsions. EEG patterns in three of the patients were compatible with encephalopathy. Other clinical manifestations included: follicular tonsillitis in two patients, diarrhea in two, pneumothorax in one, and shock with disseminated intravascular coagulation in one. The spectrum of adenovirus Type 3 infection reported here has been described previously only in the viral hemorrhagic fevers. This adenovirus Type 3 infection shares the potential for disseminated disease that has been described previously for Type 7, simulating Reye's syndrome.

Serious hepatotoxicity is uncommon with the proper therapeutic use of non-narcotic analgesics but experience with new non-steroidal anti-inflammatory drugs (NSAIDs) is limited. Drugs such as ibufenac, fenclofenac and benoxaprofen were withdrawn from the market because of hepatotoxicity, and liver damage has been reported on occasion with virtually all non-narcotic analgesics. However, a clear pattern of toxicity with characteristic clinical, biochemical and histopathological abnormalities has emerged with relatively few. With the exception of acute hepatic necrosis following overdosage of paracetamol, little is known of the mechanisms of liver injury induced by non-narcotic analgesics. Involvement of the liver in a generalised drug reaction does not imply specific hepatotoxicity. About 50% of patients given aspirin regularly in anti-inflammatory doses develop mild, dose-dependent reversible liver damage as shown by elevation of the plasma aminotransferase activity. Liver damage is more severe in a small minority and it may rarely be complicated by disseminated intravascular coagulation and encephalopathy with a fatal outcome. There have also been isolated reports of chronic active hepatitis associated with the use of salicylates. Salicylate hepatitis has been reported most often in young females with connective tissue diseases. Many patients with Reye's syndrome have been given aspirin during the prodromal phase, and this serious condition closely resembles subacute salicylate intoxication in children. Salicylate probably has a causal or contributory role in Reye's syndrome, but many refuse to accept this and the issue is the subject of heated debate. Paracetamol in overdosage causes acute hepatic necrosis, and liver damage has been attributed to its therapeutic use. However, most reports have involved chronic alcoholics who took excessive doses and in these patients the clinical, biochemical and pathological findings were typical of paracetamol overdosage. Many authors have failed to make the distinction between therapeutic use and a therapeutic dose. In other cases liver damage could have been caused by exposure to other agents, viral infection or naturally occurring liver disease. If these cases are excluded, there are very few reports of liver damage associated with the proper therapeutic use of paracetamol. In some cases, the picture resembled chronic active hepatitis but no causal relationship has been established between this condition and paracetamol use. Paracetamol does not cause deterioration in liver function in patients with chronic liver disease.(ABSTRACT TRUNCATED AT 400 WORDS)

CT/MRI findings, laboratory examinations and prognoses of 42 patients with acute encephalopathy (AE) (Japan Coma Scale > or = 200) were reported. 1. Findings on CT/MRI were divided into the following 7 categories: Group 1 (normal), Group 2 (CT/MRI looked normal in acute phase, but brain atrophy developed and progressed slowly by weeks or months), Group 3 (CT/MRI looked normal within a few days after the onset of AE, but cortical laminar necrosis developed at 4-5 days after the onset), Group 4 (marked brain edema developed within 2 days after the onset of AE), Group 5 (AE with symmetric thalamic lesions), Group 6 (symmetric pallidum, lesions on MRI which appeared after brain edema disappeared), and Group 7 (the brain shrinked during acute phase, which normalized on the follow up CT/MRI). 2. Serum AST elevated in approximately 50% of the patients with AE. Sixty percent of them exhibited DIC, whose prognoses were poor. Cerebrospinal fluids (CSF) neopterin (NP) and/or interleukin (IL)-6 were elevated in all the 8 patients examined. In the two cases whose serum NP and IL-6 were measured at the same time, their values in the CSF were higher than those in the serum in one case, and almost the same in the other. In a patient with a condition mimicking hemorrhagic shock and encephalopathy, serum IL-6 concentration was very high (94,000 pg/ml). 3. Mild hypothermia (around 34 degrees C) combined with methylprednisolone pulse therapy was excellently effective on AE. A 6-year-old boy exhibited tonsillar herniation at admission recovered well to be able to run. 4. Differentiation between Reye syndrome and HSE, and the pathogenesis of AE were also discussed.

A 28-year-old male patient, treated with prednisone for bronchitis with sibilant rales, developed fever with abdominal pain and generalized vesicular rash after coming in contact with varicella-infected children. He was hospitalized after having a seizure. Laboratory values revealed hepatitis and rapidly fulminant hepatic insufficiency with disseminated intravascular coagulation. Despite acyclovir treatment, the patient died 4 days after admission. Clinical presentation could evoke a Reye's syndrome, but liver biopsy showed massive coagulative necrosis. This report demonstrates the increased risk of complicated varicella associated with the use of corticosteroids, even for a short period of time.

We report on a 23-month-old boy with a rare complication of rotavirus gastroenteritis. He was diagnosed as acute encephalopathy with DIC accompanied with high levels of cytokines. The liver pathology also revealed mild infiltration and fatty changes. He was suspected to be suffering from a cytokine storm followed by Reye syndrome.

Acute encephalopathy is the most serious complication of pediatric viral infections, such as influenza and exanthem subitum. It occurs worldwide, but is most prevalent in East Asia, and every year several hundreds of Japanese children are affected by influenza-associated encephalopathy. Mortality has recently declined, but is still high. Many survivors are left with motor and intellectual disabilities, and some with epilepsy. This article reviews various syndromes of acute encephalopathy by classifying them into three major categories. The first group caused by metabolic derangement consists of various inherited metabolic disorders and the classical Reye syndrome. Salicylate is a risk factor of the latter condition. The second group, characterized by a systemic cytokine storm and vasogenic brain edema, includes Reye-like syndrome, hemorrhagic shock and encephalopathy syndrome, and acute necrotizing encephalopathy. Non-steroidal anti-inflammatory drugs, such as diclofenac sodium and mephenamic acid, may aggravate these syndromes. Severe cases are complicated by multiple organ failure and disseminated intravascular coagulation. Mortality is high, although methylprednisolone pulse therapy may be beneficial in some cases. The third group, characterized by localized edema of the cerebral cortex, has recently been termed acute encephalopathy with febrile convulsive status epilepticus, and includes hemiconvulsion-hemiplegia syndrome and acute infantile encephalopathy predominantly affecting the frontal lobes. Theophylline is a risk factor of these syndromes. The pathogenesis is yet to be clarified, but an increasing body of evidence points to excitotoxicity and delayed neuronal death.

Children with acute encephalopathy (AEP) or acute encephalitis(AE) show variable findings in the clinical manifestations and on the neuroimaging. Patients with AE present variable symptoms: disturbance of consciousness, seizure, ataxia, dystonia, abnormal behavior, apnea, and others. This variability depends on the location of lesions including basal ganglia, brain stem, cerebellum, or cerebral gray/white matter. In AEP, MRI findings can be categorized into (1) severe brain edema, (2) acute necrotizing encephalopathy, (3) cortical necrosis that appears 4-5 days after the onset, and (4) others. Serum AST elevates in approximately 50% of AEP patients, and among them around 60% develops DIC. The high AST group includes Reye syndrome(RS), mimic RS and AEP with shock syndrome.
