Enteral hyperalimentation in four patients with severe alcoholic hepatitis and anorexia increased spontaneous food intake, increased their nitrogen balance and the patients improved clinically. Seven patients with alcoholic hepatitis, who were clinically ill and able to eat only 410-1,100 calories per day, were given a 900 mosM/l. parenteral "hyperalimentation" solution by a peripheral vein (P-900). The intravenous nutrition provided daily 51.6-77.4 gm. amino acids in addition to oral intake. All patients improved. None developed detectable encephalopathy after 16-42 days of P-900 therapy. Five additional patients had ascites and alcoholic hepatitis. The daily infusion of 2,000 ml. P-900 was not associated with hyponatremia, renal failure or encephalopathy in four of these five patients who improved and continued their diuresis. P-900 therapy was discontinued in one because of progressive hyponatremia. The observations indicate that over and above the maximum tolerable oral nutrition, intravenous nutrition can be effectively utilized by clinically ill, jaundiced patients with alcoholic hepatitis without precipitating encephalopathy or interference with standard therapy of ascites.

Symptomatic viral hepatitis A usually only requires supportive therapy and the majority of cases are managed in the community. The prodromal symptoms of nausea, anorexia and lethargy tend to improve with the onset of clinical jaundice. Fulminant hepatic failure is said to be an uncommon complication, occurring in only 0.14-0.35% of hospitalized cases. However, an increasing incidence has been documented in some northern European countries where up to 20% of cases of fulminant viral hepatitis is due to hepatitis A. This trend parallels the increasingly delayed exposure to hepatitis A and the increased severity of the illness when contracted in later life. The risk of developing fulminant hepatic failure is best monitored using coagulation factor assays, with the prothrombin time and factor V levels being the most favoured. The diagnosis is established with the onset of encephalopathy. Patients progressing to grade 4 encephalopathy have a reasonably good prognosis compared to other aetiologies and survival rates of up to 67% have been obtained with medical management, despite the co-existence of such complications as cerebral oedema, renal and respiratory failure and the metabolic sequelae of acute liver failure. Nevertheless, some patients require emergency liver transplantation and 10 such patients have been reported to date. Transplantation is especially required in older patients (> 40 years) and those who are jaundiced for > 7 days before the onset of encephalopathy. The serum bilirubin and the prothrombin time complement these parameters in the decision making process.

Twenty-four cases of dengue haemorrhagic fever/dengue shock syndrome were studied in Delhi in the months of September and October, 1988. The majority of these cases were boys aged 6-10 years. Classical symptoms of dengue (fever, headache, aesthesia, myalgia) occurred in all the patients. Digestive symptoms (nausea, vomiting, anorexia, abdominal pain and hepatomegaly) were also common. Haemorrhagic manifestations were present in 41.7% of the cases. Of these, 90% had gastrointestinal haemorrhages. Shock occurred in 17 cases (70.8%). Thrombocytopenia and prolongation of coagulation profile were found in 62.5% of cases. Three patients (12.5%) who presented with encephalopathy died. The other 21 patients recovered after an average period of 2-8 days.

In Japan, acute encephalopathy with hepatic steatosis resembling Reye's syndrome has been reported to occur after treatment with the pantothenic acid antagonist, calcium hopantenate. We studied the causal relationship and the pathogenesis in dogs. The agent was administered to seven dogs at increasing doses over a period of 8 weeks. Anorexia, vomiting, and diarrhea were common clinical findings. In four dogs, coma suddenly developed after the appearance of gastrointestinal signs. Three animals died during periods when they were not under direct observation. The effects of the agent appear to be related to dose. Laboratory findings representing significant changes at the time of coma included hypoglycemia, leukocytosis, hyperammonemia, hyperlactatemia, and elevated levels of serum transaminases. Microvesicular hepatic steatosis and mitochondrial abnormalities were consistent pathological findings. The hepatic mitochondria were enlarged and characterized by an increased number of cristae and the presence of crystalloid inclusions. In a second group of four dogs, pantothenic acid was given in addition to and in the same amount as calcium hopantenate at increasing doses over a period of 8 weeks. All four dogs survived the 8 weeks and only one developed mild anorexia. No significant biochemical changes were found and neither hepatic steatosis nor mitochondrial abnormalities were observed. The addition of pantothenic acid prevented the development of the disorder in the four animals. These results show that calcium hopantenate produces acute encephalopathy with hepatic steatosis in dogs, by inducing a deficiency of pantothenic acid. The hepatic mitochondrial changes of this reaction differ from those of Reye's syndrome.

An outbreak of food poisoning resulting in 13 deaths in children occurred in Malaysia during the Chinese Festival of the Nine-Emperor Gods in 1988. The offending food was a Chinese noodle called 'Loh See Fun' (LSF). The source was traced to a factory where a banned food preservative was added to make the LSF. The food poisoning was attributable to aflatoxins and boric acid. The clinical features included vomiting, pyrexia, diarrhoea, abdominal pain, anorexia, giddiness, seizures, and eventual coma. Initially, many presented with a Reye-like syndrome. Eleven post-mortem examinations were performed. The pathological findings included extensive coagulative necrosis of the liver with proliferative 'ductal/ductular metaplasia of the hepatocytes'. Giant cell formation, central vein sclerosis, bile stasis, and steatosis were also noted. There was presence of acute tubular necrosis, superficial upper gastrointestinal erosions, and ensuing encephalopathy. The eventual cause of death is acute hepatic and renal failure.

While the rate of malnutrition is relatively modest in alcoholic patients without alcoholic liver disease, the rate of malnutrition is virtually 100% in patients with alcoholic hepatitis and/or alcoholic cirrhosis. The reasons for malnutrition in the alcoholic hepatitis patient include various factors such as anorexia, poor diet, malabsorption, and altered metabolic state. When the patient is hospitalized, the malnutrition frequently worsens because of fasting for tests, continued anorexia, and complications such as gastrointestinal bleeding. Patients with severe acute hepatitis appear to be both hypermetabolic and hypercatabolic, whereas data are much more conflicting concerning patients with more stable liver disease. Most studies suggest that patients with alcoholic liver disease require at least 60 g of protein per day to maintain positive nitrogen balance. Consistent alterations in plasma amino acid profiles occur in alcoholic liver disease, and specialized nutritional formulations have been devised to correct this amino acid profile with the intent of improving overall nutritional status, hepatic encephalopathy, and mortality. The effects of nutritional support (including use of specialized products) on outcome, on acute hepatic encephalopathy, and on chronic or latent portal systemic encephalopathy are reviewed.

Complications that can lead to death during shigellosis include intestinal as well as systemic manifestations. The former include intestinal perforation, toxic megacolon, and dehydration, and the latter include sepsis, hyponatremia, hypoglycemia, seizures and encephalopathy, hemolyticuremic syndrome, pneumonia, and malnutrition. Data on the frequency of these complications come primarily from hospital-based studies, in which sepsis-either with Shigella or with other Enterobacteriaceae-and hypoglycemia are the most common causes of death. Management of these two complications requires broad-spectrum empiric antibiotic treatment of all severely ill, malnourished patients with shigellosis as well as frequent feedings to prevent hypoglycemia. Unfortunately, in developing countries, access to parenteral broad-spectrum antimicrobial agents is often limited, and frequent feedings are often precluded by the severe anorexia that is characteristic of shigellosis. Realistic approaches to the reduction of mortality from shigellosis must continue to focus on prevention and early antimicrobial therapy rather than on treatment of established complications.

During a seven year period (1981-87), 53 cases of typhoid fever in children below five years were seen. This accounted for 13.5% of all typhoid admission in pediatrics during the above period. Predominant symptoms were fever (100%), vomiting (52.8%), diarrhea (30.2%) and anorexia (24.5%). Chills and rigor associated with fever was noticed in 38% of the children. Salmonella typhi was isolated from blood in 22 of 53 (41.7%) cases. A significant finding on peripheral smear was eosinopenia (86.8%). Complications like endotoxic shock, enteric encephalopathy and gastrointestinal hemorrhage were noticed in only few cases (7.6%). There were no deaths.

Calcium hopantenate (HOPA) has been widely used as an activator of cerebral metabolism in Japan. However, several cases of acute encephalopathy during HOPA administration were recently reported, which were characterized by marked metabolic acidosis and hypoglycemia. The encephalopathy in these patients was named Reye-like syndrome because of the similarity to Reye's syndrome in children. The purposes of this presentation are to report on 5 patients with acute encephalopathy developing during HOPA administration, to summarize their symptoms and clinical courses, and to discuss the pathogenesis of metabolic acidosis and hypoglycemia. Initial characteristics of the clinical course in all patients were loss of appetite, nausea and vomiting, followed by unconsciousness. Laboratory examinations revealed marked metabolic acidosis, severe hypoglycemia, hyperlactacidemia, leukocytosis, ketonuria, and increased Ht and BUN. A few days after development of the initial symptoms, mild renal and liver dysfunction, and elevation of serum amylase were observed in all patients. Hyperlactacidemia was present in 4 in the initial period. Blood concentration of HOPA was 2.131 micrograms/ml in patient 1 (8-10 hours after final administration), and 10.7 micrograms/ml in patient 5 (24 hours after final administration). These values are extremely high, because usually HOPA concentration is almost negligible 7 hours after the drug is taken. As the pathogenesis of acute encephalopathy due to HOPA administration, the failure of fatty acid beta-oxidation has been proposed by some investigators. However, the serum concentrations of CoA, pantothenic acid and carnitine during the initial stage were not reduced in our patients. Furthermore, it is very difficult to explain the severe hypoglycemia in terms of the beta-oxidation theory.(ABSTRACT TRUNCATED AT 250 WORDS)

Although the occurrence of Wernicke's encephalopathy (WE) in patients on dialysis is frequently alluded to, review of the literature reveals only 3 described cases. We describe 5 patients on dialysis who developed WE in the absence of alcoholism or other predisposing factors. The clinical diagnoses included uremic encephalopathy (2 patients), dysequilibrium syndrome (1), dialysis dementia (1), and brainstem hemorrhage (1). At postmortem examination, classic findings of WE were evident. The rarity of WE in patients on dialysis may in part be explained by studies indicating a genetic defect in transketolase activity. Patients on dialysis are also potentially at risk for thiamine deficiency because of anorexia, vomiting, and intravenous alimentation. Other factors altering thiamine requirements, such as glucose load or infections, may also contribute. Preventable and potentially curable, WE should be suspected in all patients on dialysis who have an unexplained neurological picture.
