Food intake, appetite and a variety of feelings were measured pre- and post-operatively in obese patients undergoing jejuno-ileal bypass surgery. Decreased food intake correlated closely with the amount of weight loss at both 4 and 30 months after surgery. Malabsorption correlated with weight loss at 4 months but not 30 months post-operatively. The cause of the decreased food intake is unknown and cannot be completely explained by either depression, nausea, malabsorption, liver disease, an attempt to avert diarrhoea, or decreased appetite.

A 39-year-old woman was evaluated for possible liver transplantation due to rapidly developing hepatic failure 4 weeks after initiation of oral minocycline 100 mg twice a day for the treatment of acne. The patient developed a maculopapular rash, malaise, fever, nausea, and vomiting 2 weeks prior to admission to the hospital. On admission, her symptoms rapidly progressed to liver failure characterized by rapidly rising liver enzyme levels, worsening encephalopathy, and coagulopathy. Viral hepatitis serologies and blood cultures were all negative. After intensive supportive care for 2 weeks, the patient's condition gradually improved and she was discharged with mildly elevated liver enzyme levels and pruritus, without need of liver transplantation. Minocycline-induced hepatic injury is an idiosyncratic reaction with a sensitization period that appears to be 3-4 weeks in duration. The characteristic features include rash, fever, lymphadenopathy, and eosinophilia, as well as severe alterations in liver function. The high liver enzyme levels and the significant prolongation of the prothrombin time suggest massive hepatocellular damage. In light of the profound liver damage that occurs with this adverse reaction, care should be taken in administering minocycline to patients who have concomitant liver disease. It is recommended that patients should be instructed as to the possible signs and symptoms of toxicity and be monitored for evidence of idiosyncratic reaction or liver failure.

Enoximone, a new phosphodiesterase-inhibitor with positive inotropic and vasodilating activities is available for intravenous use in patients with severe heart failure. A review of the current knowledge regarding the adverse effects of this substance reveals that they are characterized by cardiovascular, central nervous, and gastrointestinal side effects. Adverse effects occurred in 20% of patients and were mostly due to the pharmacological properties of enoximone. Cardiovascular side effects (10%) were the most frequent; ventricular and supraventricular arrhythmias were most common. Two to three percent of the patients experienced hypotension due to the vasodilator activity of enoximone. Headache, insomnia, and anxiety were the most frequent adverse effects on the central nervous system. Three percent of the patients treated experienced vomiting, nausea, abdominal pain, and diarrhea. An increase of liver enzymes and serum glucose could be observed, mostly in patients with previous liver disease or diabetes. Pharmacokinetic drug interactions are not known; possible pharmacodynamic interactions result from the pharmacological properties of the drugs. Intravenous therapy with enoximone causes a few serious side effects that can only be controlled by careful observation of the patients treated.

In a 14-day multiple-dose study the pharmacokinetics of paroxetine was investigated in 12 patients with alcoholic cirrhosis and in 6 subjects without liver disease. The dose of 20-30 mg paroxetine daily was adjusted to the reduction in liver function, as assessed by the galactose elimination capacity. Accordingly, all but two of the cirrhotic patients received 20 mg, while all six control subjects received 30 mg. Dose-corrected, trough drug concentration at steady state (CSSmin) and dose-corrected AUC24h were significantly higher in the patients with liver diseases than in the control subjects [3.4 vs 1.5 ng.ml-1 per mg paroxetine and 89 vs 43 h (ng).ml-1 per mg paroxetine]. The elimination t1/2 was prolonged [83 vs 36 h], but the difference was not statistically significant, and the cirrhotic patients were still able to clear almost all the paroxetine by metabolism. All but two patients with cirrhosis experienced nausea during the first two or three days after the first dose, while none of the controls had this symptom. The study showed slower elimination of paroxetine and consequently higher plasma levels in patients with cirrhosis, suggesting that in the latter the dose of paroxetine should be in the lower end of the therapeutic range.

A phase II evaluation of UFT, a mixture of tegafur and uracil, was performed in 13 patients with non-small cell lung cancer (eight patients with adenocarcinoma and five patients with squamous cell carcinoma). UFT at a dose of 600 mg was given per os every day for more than four weeks. Among 12 evaluable patients, one patient with adenocarcinoma of the lung showed partial response. The response rate for UFT was 8.3%. Toxic effects included anorexia (31%), nausea (15%), liver disorder (15%), and pigmentation (8%).

Differential diagnosis of viral hepatitis begins with a check for darkened urine and bile in the urine. These hallmarks of conjugated hyperbilirubinemia immediately rule out prehepatic liver disease. Next, studies are done for the elevated transaminase levels that are characteristic of hepatitis infection, and a thorough history is taken to rule out drug- and toxin-induced hepatitis that may mimic acute viral hepatitis. Elevated alkaline phosphatase is a good marker of cholestasis. Ultrasonography can clarify this diagnosis. The classic presenting symptoms of viral hepatitis are jaundice, nausea, vomiting, malaise, anorexia, and dull right upper quadrant pain. However, serologic studies are needed to detect the presence of specific viral agents.

Differences in the pharmacokinetics of alcohol absorption and elimination are, in part, genetically determined. There are polymorphic variants of the two main enzymes responsible for ethanol oxidation in liver, alcohol dehydrogenase and aldehyde dehydrogenase. The frequency of occurrence of these variants, which have been shown to display strikingly different catalytic properties, differs among different racial populations. Since the activity of alcohol dehydrogenase in liver is a rate-limiting factor for ethanol metabolism in experimental animals, it is likely that the type and content of the polymorphic isoenzyme subunit encoded at ADH2, beta-subunit, and at ADH3, the gamma-subunit, are contributing factors to the genetic variability in ethanol elimination rate. The recent development of methods for genotyping individuals at these loci using white cell DNA will allow us to test this hypothesis as well as any relationship between ADH genotype and the susceptibility to alcoholism or alcohol-related pathology. A polymorphic variant of human liver mitochondrial aldehyde dehydrogenase, ADLH2, which has little or no acetaldehyde oxidizing activity has been identified. Individuals with the deficient ALDH2 phenotype do not have altered ethanol elimination rates but they do exhibit high blood acetaldehyde levels and dysphoric symptoms such as facial flushing, nausea and tachycardia, after drinking alcohol. Because acetaldehyde is so reactive, it binds to free amino groups of proteins including a 37 kilodalton hepatic protein-acetaldehyde adduct and may elicit an antibody response. We would predict that individuals who have low ALDH2 activity because of liver disease or because they have the inactive ALDH2 variant isoenzyme might form more protein-acetaldehyde adducts and elicit a greater immune response. These adducts may represent good biological markers of alcohol abuse and may also play a role in liver injury due to chronic alcohol consumption.

A 39 year old woman was admitted to a maternity unit at 34 weeks' gestation with nausea, vomiting, and jaundice. Her condition deteriorated, and she was transferred to hospital, deeply unconscious and hypotensive. The diagnosis of acute fatty liver of pregnancy was initially suggested by the typical history of prodromal malaise and vomiting and the rapid onset of hepatic encephalopathy with profound hypoglycaemia and only small increases in transaminase activities. Computed tomography was performed: there was no enlargement of the liver or spleen, but the attenuation value over the liver indicated appreciable fatty infiltration of the liver, establishing the diagnosis of acute fatty liver of pregnancy. Computed tomography is of value in the diagnosis of liver disease of late pregnancy, and this technique may become the method of choice for the investigation of acute fatty liver of pregnancy.

A 68-year-old man without previous hepatobiliary or pancreatic disease was admitted after five attacks of nausea, vomiting, abdominal pain and high fever. Laboratory investigations indicated cholestatic liver disease and pancreatitis. For 1.5 years the patient had occasionally been taking a non-steroidal anti-inflammatory drug, sulindac (clinoril, MSD, New York), for osteoarthritis. On suspicion of a drug-associated disease, a rechallenge experiment was performed with sulindac. Five hours after drug administration symptoms recurred. There was a pronounced increase in serum alkaline phosphatase and amylase. A liver biopsy 3 d later showed portal tract inflammatory infiltration and abnormal interlobular bile ducts with degeneration and necrosis of the epithelium and neutrophilic infiltration of the ducts. Sulindac-induced cholangitis has not been described previously. The pathogenetic mechanism is considered to be an immunoallergic idiosyncratic reaction to the active metabolite of sulindac absorbed by the bile duct epithelium. The lesion is apparently reversible.

This study reviews liver disease in toxemia of pregnancy based on 102 cases submitted to the Armed Forces Institute of Pathology. The common clinical features were right upper quadrant and epigastric pain, nausea, vomiting, and elevation of the serum transaminases. Jaundice occasionally developed. These occurred in severe preeclampsia or eclampsia and their cause was usually recognized. However, hepatic symptoms and signs did result in inappropriate diagnoses and misdirected therapy. Such confusion occurred when these were the initial problems confronting the clinician in women presenting with advanced toxemia due to poor prenatal care. They were also likely to be misleading when other more classic parameters, such as blood pressure and proteinuria, were only midly abnormal. Central nervous system complications were the common cause of death but liver disease could be partially or wholly responsible. Extensive periportal lesions, hepatic hematomas, spontaneous rupture, and infarction all contributed to hepatic injury and to morbidity. Fibrin deposition, hemorrhage, or both in the periportal areas was characteristic of the histopathology. Scanning electron microscopy validated this spectrum of change. A toxemic vasculopathy related to severe vasospasm in the hepatic arterial circulation may be responsible.
