Serum zinc and copper levels were studied in relation to in vitro and in vivo drug metabolism in 25 alcoholics, in whom various diseases of the liver had been diagnosed by histology. Serum zinc was elevated in alcoholics with normal or fatty liver and was low in those with alcoholic hepatitis or cirrhosis. There was a significant positive correlation between serum zinc and cytochrome P-450 content of liver biopsies. The relationship between zinc and antipyrine half-life was significant and non-linear. Serum copper level was elevated in all the alcoholics and no significant relationship could be found between copper and drug metabolism in alcoholics. The findings suggest parallelism between changes in serum zinc and indices of drug metabolism in alcoholics.

Acute alcoholic hepatitis is an anatomical (fatty liver with sclerosing hyaline necrosis) and a clinical (hepatomegaly with a variety of symptoms of hepatic failure) entity arising out of chronic alcoholism, and of a typically 'pre-cirrhotic' state. Although fatal in 25% of acute cases due to failure of homeostasis, it often leaves a centrilobular scarring necrosis which in more than 60% of cases progresses to nodular cirrhosis. Continued alcoholism worsens the prognosis. Alcoholic hepatitis may be confused with acute abdominal catastrophes or with a hepatoma. The characteristic Mallory bodies found on liver biopsy are found rarely in non-alcoholic hepatitis. There is no effective treatment for this disease except reduction of alcohol intake; indeed, the disease may become self-perpetuating.

"Cures" embrace by definition a broad spectrum starting from taking waters in health resorts to hospital treatment in modern rehabilitation centers. The effectiveness of traditional cure procedures is discussed. Effectiveness of drinking cures, baths and mud packs in liver disease has not yet been proven. Controlled trials are necessary. Clinical treatment is indicated in alcoholic liver damage, viral hepatitis with a protracted course, chronic aggressive hepatitis and compensated cirrhosis of the liver; such treatment, however, is questionable in fatty liver and in chronic persistent hepatitis. Data concerning the effectiveness of treatment of chronic liver diseases are given. The following conclusions are drawn: patients with liver disease ought to be hospitalized when undergoing cures, indications have to be precised, collaboration of patients has to be stimulated, hospital discipline has to be tight, therapy of alcoholism has to include several psychosocial aspects, treatment after leaving hospital has to be improved.

Oxphenisatin is known to induce liver damage and is suspected to cause or perpetuate chronic liver disease. In order to evaluate the hepatotoxic effect of long-term therapy with oxyphenisatin 26 consecutive patients with rheumatoid arthritis were investigated for the presence of liver disease. In all cases, liver biopsy, biochemical liver function tests and determination of Hepatitis-B antigen were performed. Ten patients showed no pathological changes in the liver biopsy and a further 2 had only non-specific changes. Seven patients had fatty liver, 5 passive congestion, one haemosiderosis and only one had cirrhosis of the liver. No correlation was found between the activity of rheumatoid arthritis, and duration of the disease, the drug therapy given, and the liver damage.

A model has been developed for the administration to rats and baboons of ethanol as part of a nutritionally adequate liquid diet. With this regimen, ethanol intake was much higher than with conventional procedures. All animals gained or maintained their body weight, and liver morphology was normal in the controls. Isocaloric substitution of carbohydrate by ethanol (36% of total calories in rats and 50% in baboons) resulted in the production of fatty liver in all animals, while the baboons also developed alcoholic hepatitis and cirrhosis with increased activities of serum glutamic oxaloacetic transaminase. Inebriation and manifestation of dependence on withdrawal of the diet were observed in baboons and quantitated in the rat. Chemical alterations produced by ethanol at the fatty liver stage were characterized by hyperlipemia, striking triglyceride accumulation in the liver, and enhanced activities of microsomal drug metabolizing enzymes, including the microsomal ethanol oxidizing system (MEOS). In showing that all aspects of liver injury observed in alcoholics can be reproduced in animals by the feeding of pure ethanol with an adequate diet, this study incriminates ethanol itself as a cause for the hepatic complications. This new experimental model is proposed as a tool for the study of the pathogenesis and treatment of alcoholic liver injury and dependence.

This study reproduces in experimental animals the sequential development of all the liver lesions seen in the human alcoholic: in 15 baboons fed ethanol, all developed fatty liver, five progressed to hepatitis, and five had cirrhosis. Maintenance of a nutritionally adequate regimen despite the intake of inebriating amounts of ethanol (50% of total calories) was achieved by incorporation of the ethanol in a totally liquid diet. Upon ethanol withdrawal, signs of physical dependence, such as seizures and tremors, developed. Ultrastructural changes of the mitochondria and the endoplasmic reticulum were already present at the fatty liver stage and persisted throughout the hepatitis and cirrhosis. The lesions were similar to those observed in alcoholics (including the inflammation and the central sclerosis) and differed from the alterations produced by choline and protein defiencies. At the fatty liver stage, some "adaptive" increases in activity of microsomal enzymes [aniline hydroxylase (EC 1.14.14.1) and the microsomal ethanol oxidizing system] were observed, but these tended to disappear with the development of hepatitis and cirrhosis. Fat accumulation was also much more pronounced in the animals with the hepatitis as compared with those with simple fatty liver (an 18-fold compared with 3- to 4-fold increase in liver triglycerides). The demonstration that these lesions can develop despite an adequate diet indicates that in addition to correction of the nutritional status, control of alcohol intake is mandatory for the management of patients with alcoholic liver injury.

Liver biopsies obtained from 100 alcoholic patient attending a clinic primarily for the management of their alcoholism, have been reviewed. The morphological appearances have been correlated with histories of alcohol consumption and with clinical and biochemical findings. There were 77 men and 23 women. Eight biopsies appeared normal, 62 showed fatty liver with or without fribrosis, 17 had alcoholic hepatitis with or without fibrosis and 13 had alcoholic hepatitis with established cirrhosis. Patients with fatty liver had drunk as long and as heavily as those with alcoholic hepatitis, suggesting that some other factor in addition to alcohol is of importance in the development of alcoholic hepatitis. Clinical and biochemical abnormalities showed no constant relationship to histological findings. Thus liver biopsy would seem to be an essential part of the full clinical assessment of the alcoholic patient.

Determination of histocompatibility antigens in 63 patients with alcoholic liver disease showed that HLA-B8 was more prevalent in patients with cirrhosis than in controls, but among those with fatty liver and minimal fibrosis the prevalence of this antigen was normal. Another noticeable difference was the absence of HLAA28 in the cirrhotic group. In the total series of 219 patients the prevalence of antinuclear and smooth muscle antibodies was raised; they were especially prevalent in patients with cirrhosis. Raised serum IgA and IgG concentrations were also common (found in 50% and 37% respectively) and were again significantly associated with cirrhosis. In contrast, serum IgM levels, which were raised in 46% of cases, were not significantly related to the presence of cirrhosis but correlated significantly with the degree of portacaval shunting. These results support recent evidence suggesting that immune responses may be implicated in alcohol-induced liver damage, particularly in its progression to cirrhosis.

Transient bacteremia associated with percutaneous liver biopsy was studied by pour-plate blood cultures, which were obtained immediately before and after the procedure and 5, 10, 15, and 30 min later in 89 patients. Part of the liver tissue was also cultured in all patients. Histological diagnoses included hepatitis, cirrhosis, cholangitis, fatty liver, granulomata, metastatic liver disease, lymphoma, and miscellaneous disorders. All blood cultures obtained before liver biopsy were sterile. Bacteremia was demonstrable in 12 patients (13.48%). In most of these patients, blood cultures were positive for as long as 15 min after liver biopsy; all cultures were negative at 30 min. Among the bacteria associated with 12 episodes of bacteremia were Escherichia coli, Klebsiella, Bacteroides, enterococci, diphtheroids, Staphylococcus aureus, alpha-hemolytic Streptococcus, and Streptococcus pneumoniae. The patients with positive liver biopsies had a higher incidence of bacteremia (83.3%) than did the patients whose liver biopsies were sterile (8.r%); this difference is stastically significant (P smaller than 0.01). Thus, liver biopsy can be associated with transient bactermia.

The influence of sex, age, and liver function on the androgenmetabolizing capacity of the liver was investigated. To that end, testosterone was administered orally to healthy men, women and prepubertal boys as well as to men with liver dysfunction. While normal men (n = 17) and men with fatty liver (n = 9) showed no rise in circulating plasma testosterone levels and only a slight increase in androstenedione, a steep increase in both steroids was observed in men with liver cirrhosis (n = 7). Unlike adult men, boys (n = 7) and women (n = 6) also showed elevated testosterone levels after oral administration of this steroid. It is concluded that the hepatic capacity to metabolize testosterone is influenced by sex, stage of development, and liver function. It seems possible that peripheral concentration of testosterone after its oral administration can serve as a clinical test for liver function.
