Alcoholic liver disease presenting with marked elevation of serum alkaline phosphatase. A combined clinical and pathological study.

Twenty patients with longstanding alcoholism and biopsy-proven alcoholic liver disease presented with marked elevation of serum alkaline phosphatase (in excess of four times the upper limit of normal). None had a past or present history to suggest pancreatitis or biliary tract disease, nor had any of these patients recently taken medication which could be implicated in cholestatic jaundice. Thirteen (65%) of this group either had radiologic or post mortem confirmation of nonobstructed biliary systems. The histologic findings in this group of patients were compared with those of a group of patients with alcoholic liver disease and normal or only mild elevation of serum alkaline phosphatase. Significantly more hepatocellular necrosis (P less than 0.05), alcoholic hyaline (P less than 0.02), and cholestasis (P less than 0.002) were noted in the severely hyperphosphatasemic group. Minimal degrees of steatosis were found in both groups. These data indicate that intrahepatic cholestasis occurs in patients with alcoholic liver disease, and this may often be secondary to alcoholic hepatitis. Overemphasis has previously been given to alcoholic fatty liver as a cause of this syndrome.

Anticore antibody screening of transfused blood.

Aliquots of 130 HB8Ag negative units of blood which were administered to 26 recipients were tested under code for anti-HBc by a solid phase radioimmunoassay technqiue. 14 of the 26 recipients developed posttransfusion hepatitis (PTH), including 6 cases of hepatitis B. Anti-HBc was detected in 7 or 5.3% of 130 donor units. Of the 14 patients acquiring PTH, 6 received a unit of anti-HBc-positive blood. Type B hepatitis occurred in 4 of the 7 anti-HBc recipients, and non-type B hepatitis in 2. Only 1 of 12 recipients who failed to develop PTH had received a unit containing anti-HBc.

Non-A, non-B hepatitis transmission in chimpanzees: a project of the transfusion-transmitted viruses study group.

Experimental transmission of non-A, non-B hepatitis was apparently accomplished in 5 chimpanzees following inoculation with presumably infectious human sera. Administration of sera from implicated donors with normal alanine aminotransferase (ALT) values, as well as from those with abnormal ALT levels, resulted in the development of ALT abnormalities in the inoculated chimpanzees. Transmission from donors with normal ALT values implies that healthy carriers of non-A, non-B virus exist. Evidence is presented which indicates that a period of viremia precedes the clinical illness by at least 12 days.

Radioimmunoassay for antibody to hepatitis B surface antigen shows transmission of hepatitis B virus among household contacts.

The epidemiology of infections with hepatitis B virus was studied by measurement of serum antibodies to hepatitis B surface antigen (HBS Ag) with the radioimmuno-precipitation test. Prospective studies of household contacts of HBS Ag-positive patients with acute hepatitis demonstrated that four of 41 children and one of 60 adults experienced anicteric seroconversions. Two of the 60 adults also had mild icteric hepatitis and became chronically antigenemic. Neither HBS Ag nor antibody to HBS Ag was detected in follow-up blood samples from 85 seronegative contacts of HBS Ag-negative patients with hepatitis, although seven icteric secondary cases were identified. Household contacts of HBS Ag carriers frequently had serologic evidence of exposure to hepatitis B virus (44% of adults), but the remainder had neither detectable antigen nor antibody.

Methadone treatment: program evaluation and dose response relationships.

Data from a heterogeneous group of 155 clients in a Methadone Treatment Program were analyzed for (A) number of possible methadone administrations since S joined the program, (B) actual number of methadone administrations received, (C) spottiness (A-B), and (D) presence of illicit drugs in urine analysis reports. Data were evaluated for three separate time spans which corresponded with three programmatic changes. Results indicate that initially high blockading doses of methadone are effective in reducing illicit drug use, but as length of time in program increases, the efficacy of low doses of methadone in reducing illicit drug use increases. At least one programmatic change, a more stringent selection procedure, was demonstrated to be highly successful in reducing illicit drug use.

Epidemiology of hepatitis B virus in an institution for mentally retarded persons.

Sera from patients and employees of the Lynchburg Training School and Hospital were tested for Hepatitis B surface antigen by complement fixation test and antibody against Hepatitis B surface antigen by radioimmunoprecipitation test. Hepatitis B surface antigen was detected in 20% of the Down's syndrome patients and 7 percent of the matched other retarded patients. Antibody against Hepatitis B surface antigen was detected in 40% of the Down's syndrome and 57% of the matched other retarded patients. Hepatitis B virus infection as measured by presence of either Hepatitis B surface antigen or antibody was similar in the Down's syndrome patients (59%) and the matched other retarded patients (63%). Male patients had a higher frequency of Hepatitis B surface antigen chronic carriers and a lower frequency of antibodies to Hepatitis B surface antigen than the female patients. No relationship between age at time of first institutionalization and prevalence of Hepatitis B virus infection was demonstrated. However, it was observed that patients institutionalized at an earlier age were more likely to be housed in wards with a high frequency of Hepatitis B surface antigen. Increased length of institutionalization was associated with increased prevalence of Hepatitis B virus infection. Antibody to Hepatitis B surface antigen was detected in 33% of the employees. Employees who worked on wards with a high frequency of Hepatitis B virus infection had a high frequency of Hepatitis B surface antibody (50%) whereas those working on wards with a low frequency of infection had a low frequency of Hepatitis B surface antibody (9%).

Angiosarcoma of the liver associated with Fowler's solution (potassium arsenite).

A patient with an angiosarcoma of the liver associated with the chronic ingestion of Fowler's solution (potassium arsenite) is described. The patient's clinical course was characterized by upper gastrointestinal hemorrhage, recurrent hemoperitoneum, hepatic failure, and, subsequently, the appearance of an angiosarcoma of the skin. Selective angiography demonstrated features consistent with both hepatoma and cavernous hemangioma. The hepatic toxicity and the carcinogenicity of arsenic are reviewed, with particular reference to Fowler's solution, which previously has been widely used for the treatment of psoriasis. The long latency period for the development of the malignancies is emphasized.
