A clinical, biochemical, and pathological study was performed in 38 chronic HBsAg carriers. The study group is a part of 393 carriers found among 117 705 voluntary blood donors at the National Blood Bank, Hospital del Salvador, Santiago, Chile. None of the 38 carriers had a past history of illicit drug abuse, hepatitis, or work involving a high risk of hepatitis B virus infection. Ten individuals had a normal liver biopsy, 17 reactive non-specific hepatitis, one fatty changes, four chr onic persistent hepatitis, one aggressive hepatitis, two post-necrotic cirrhosis, and three alcoholic cirrhosis. There was not a close correlation between liver function test and liver histology. The most significant laboratory finding was the postivity of alpha fetoprotein in two cases. During the follow-up the two alpha fetoprotein patients presented a hepatocarcinoma 12 and 14 months after admission to the study.

Alcoholism is the most common form of drug abuse and alcoholic liver disease is a major health problem which in terms of increasing incidence is only rivaled by viral hepatitis. Cirrhosis of the liver, most of which is probably alcoholic, is among the leading causes of morbidity and mortality between the ages of 25 to 65 in Western countries. Alcoholic liver disease includes adaptive and toxic ultrastructural alterations, alcoholic fatty liver, alcoholic hepatitis and alcoholic cirrhosis, later accompanied by hepatoma.

The epidemiology of HDV infection in Italy was assessed in a retrospective study involving 1556 HBsAg chronic carriers on their first presentation at one of the 35 Liver Units in 1987. Total anti-HD was detected in 23.4% of HBsAg carriers and was significantly more frequent in southern than in northern Italy (26.6% vs. 19.1%, p less than 0.01). Age distribution showed that 73% of the anti-HD-positive subjects, but only 56% of the anti-HD-negative subjects, were under 40 years of age (p less than 0.01). Anti-HD prevalence increased with the severity of the liver disease from 3.8% in healthy carriers to 42.5% in cirrhosis. No geographical statistical difference was found among HBsAg healthy carriers or subjects with chronic persistent hepatitis (CPH), while among patients with chronic active hepatitis (CAH) or cirrhosis anti-HD prevalence was much higher in the south (p less than 0.01). The various potential risk factors were evaluated by multiple logistic regression analysis. HDV infection was independently related to young age, residence in the south, i.v. drug abuse, a large family and household contact with an anti-HD-positive carrier. No association was found with blood transfusion or male homosexuality. These findings confirm that HDV infection is endemic in Italy, particularly in some southern areas, where intrafamily contact probably at a young age may favour the spread of the infection.

A historical cohort study was carried out in Rome to examine overall and cause-specific mortality among intravenous drug users (IVDUs). A total of 4200 IVDUs (3411 men and 789 women) enrolled in methadone treatment centers between 1980 and 1988 were studied. There were 239 deaths during the follow-up period. The overall SMR was 10.10 in the entire cohort (95% confidence interval, 8.86-11.47), 9.30 in males and 18.07 in females. A large excess of mortality in both sexes was found for infectious, circulatory, respiratory, and digestive diseases as well as for violence, overdose, AIDS, and unknown or ill-defined causes. Tumors and suicide were excessive only in males. Deaths due to drug overdose, violence or trauma, and cirrhosis accounted for 63.6%, AIDS for 7.1%, endocarditis and other bacterial infections for 7.1%, and neoplasms for 3.8% of total mortality. These findings document serious health consequences of drug abuse in Italy.

The abuse by injection of heroin or other drugs has long been associated with liver disease caused by hepatitis B virus (HBV) and other viruses. Increasingly severe hepatic and virological complications of parenteral drug abuse have been reported due to infection with new viruses or concomitant alcohol abuse. The hepatitis delta virus (HDV) can replicate and cause liver infection only in the presence of HBV; such infection in HBV carriers may cause rapidly progressive and clinically significant liver disease. Liver cirrhosis is frequently detected in parenteral drug abusers who have chronic infection with both HBV and HDV or who also abuse alcohol. More than one quarter of those persons with acquired immunodeficiency syndrome (AIDS) in the United States of America are homosexual or heterosexual males who are parenteral drug abusers. Existing evidence implicates parenteral drug abusers in the spread of hepatitis viruses and the retrovirus associated with AIDS to the general population. To cope with these serious problems the authors suggest that more intensive international co-operation is needed, particularly with a view to promoting data collection, research and the exchange of knowledge and experience on measures that have been effective in dealing with parenteral drug abuse and its complications.

Currently, average apparent consumption of alcohol for all persons older than 14 is 10 percent higher than 10 years ago, and is equivalent to about 2.75 gallons of ethanol per person per year. Approximately 10 million adult Americans (i.e., 7 percent of those 18 or older) can be considered problem drinkers. Youthful problem drinkers, aged 14 to 17, are estimated to number more than 3 million and comprise 19 percent of this age group. In addition to the social costs, the economic costs to society as a result of alcohol misuse are substantial--an estimated +49.4 billion in 1977. Ten percent of all deaths in the United States are alcohol-related. Cirrhosis, which is largely attributable to alcohol consumption, ranks among the 10 leading causes of death. Alcohol use also is associated with cancer of the liver, pancreas, esophagus, and mouth. Alcohol consumption during pregnancy is associated with a wide range of possible harmful effects to the fetus--among them decreased birth weight, spontaneous abortion, and physical and mental birth defects. Drug misuse is also an expanding problem. There are some 16 million current marijuana users. The popularity of cocaine continues to increase--over 10 million Americans have tried cocaine at least once and there are an estimated 1 to 2 million current users. Misuse of barbiturates remains a significant problem with at least 1 million persons believed to misuse these drugs and the 30,000 estimated to be addicted to them. In addition, heroin addiction is still considered by many to be the most serious drug problem in the United States. Drug misuse leads to a number of social and health problems. Excessive doses of depressants can result in both physical and psychological dependence. The toll from heroin includes premature death and severe disability, family disruption, and crime committed to maintain the habit. Misuse of hallucinogens often results in emergency room visits. A special problem is the relationship of marijuana to automobile accidents, especially when used in combination with alcohol. While these events are disconcerting, progress has been made. National surveys indicate no changes in peak quantity consumed by teenagers 12 to 17 or in regularity of their drinking, between 1974 and 1978. Alcoholism mortality rates and alcoholic psychosis rates have shown little overall increase between 1950 and 1975. And similar encouraging trends have occurred in drug misuse. Several drug abuse data sources simultaneously have begun to reflect a down turn in use rates. These early indicators must be monitored overtime before conclusions as to their true significance can be evaluated.Nonetheless, the daily use of marijuana by high school seniors dropped from a peak of 10. 7 percent in 1978 to 7.0 percent in 1981. Daily regular cigarette smoking among seniors also declined dramatically-from 28 percent to 10 percent in the same period. The use of the hallucinogenic drug PCP also dropped markedly. Cocaine,heroin and sedative use among high school seniors remained relatively stable in terms of annual and lifetime prevalence, although the use of stimulants rose markedly. Of the 16 categories of drug use analyzed in the recent High School Senior Drug Use Survey, drug use in 15 categories was either stable or was decreasing(the second year of decline since the survey began in 1975).

Liver sections from 273 drug addicts submitted to medicolegal autopsy at the Institute of Forensic Medicine in Copenhagen in the period 1975-1979 were studied. In 65% of the cases non-specific portal inflammation only was found. Birefringent material--identified as the mineral talc (magnesium silicate) was observed in 38% of the cases; in these cases non-specific portal inflammation was always present. Changes compatible with acute or chronic persistent hepatitis or hepatitis sequelae were observed in 8% of the cases; cirrhosis in 3%. HBs-antigens were detected in 4%. In 22% fatty infiltration was present; in 4% as the only abnormal finding. Finally no pathological changes were found in 6%. The results were related to anamnestic information of kind and duration of drug abuse and to the cause of death. Furthermore a comparison was performed between the groups with and without birefringent material. The data suggest that the birefringent material may be of importance to the pathogenesis of the non-specific portal inflammation.

Formerly the diagnosis of acute and chronic non-A, non-B hepatitis was made by the exclusion of other causes. However, in 1989 cloning of an antigenic component of the hepatitis C virus (HCV) was reported. This led to first- and second-generation tests for antibody to HCV (anti-HCV) in serum. HCV has been associated with acute and chronic posttransfusion and sporadic non-A, non-B hepatitis, and with hepatocellular carcinoma. Viral HCV RNA can be estimated with the polymerase chain reaction test, but this technically difficult test is not generally available. The entire viral genome has been sequenced. The envelope region shows considerable variation, and mutant HCV infections are being described already. There are geographic variations in the prevalence of anti-HCV, but usually about 0.5% to 1% of healthy blood donors test positive. Parenteral exposure to blood, especially by transfusion or drug abuse, remains a certain means of acquiring HCV infection. The method by which millions without parenteral risk factors acquire HCV remains uncertain. Vertical transmission and sexual and family spread occur only rarely. Body secretions are free of the virus. The mode of transmission may become clarified when tests for viral HCV as opposed to anti-HCV become generally available. Acute HCV infection usually is mild, and the chronic disease is also indolent. Carriers of hepatitis B virus or alcoholics who also test positive for HCV have more serious disease. Chronic HCV infection must be distinguished from autoimmune chronic active hepatitis. The most important difference is the response to corticosteroid therapy, which is good in autoimmune hepatitis and poor in HCV-related disease. Hepatocellular carcinoma can complicate HCV-related cirrhosis, usually about 20 years after infection with HCV. Recombinant interferon-alpha is used to treat chronic HCV disease, but selection of patients, dose, and duration of therapy are uncertain. In general, 50% of patients respond to the treatment, but 50% of these will have a relapse, with an overall response rate of 25%. Liver transplantation in patients with end-stage HCV disease usually is followed by infection of the graft.

Hepatitis C virus (HCV) has been associated with acute and chronic posttransfusion and with sporadic non-A non-B (NANB) hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). Cloning of the sequence encoding an antigenic component of HCV in 1989 led to the development of tests to detect antibody to HCV in serum. Viral HCV RNA can be detected and estimated with polymerase chain reaction (PCR) and branched-chain DNA (bDNA) signal amplification tests. The entire viral genome has been sequenced. The HCV envelope region varies considerably, and infections with mutant HCV have been described. Approximately 0.5-1.5% of healthy blood donors test positive, and HCV infection can be acquired by blood transfusion or i.v. drug abuse. Vertical and sexual transmission of the virus is rare, and the transmission mode remains obscure in a large group of patients. Acute hepatitis C is mild and often asymptomatic. Chronic hepatitis C has an indolent course but may progress to cirrhosis and HCC. Recombinant alpha interferon (IF) is used to treat chronic HCV disease, but no consensus has been reached on patient selection, dose, and duration of treatment. Approximately 50% of treated patients respond, but 50-80% of responders relapse over time. Liver transplantation in patients with end-stage, HCV-related liver disease is often followed by allograft infection. Short-term survival with reinfection is good, but the long-term consequences remain to be defined.

There is a high incidence of chronic liver disease in end-stage renal failure patients on dialysis. Hepatitis C virus appears responsible for 80% of posttransfusion hepatitis, and up to 80% of sporadic hepatitis and cryptogenic cirrhosis. Anti-HCV antibodies correlate highly with the presence of active infection. The clinical implications of HCV infection in patients undergoing renal transplantation is unknown. Part I: We undertook a descriptive cross-sectional study of all renal failure patients admitted for kidney transplant between 1/84 and 12/88. Pretransplant sera were assayed for anti-HCV using an ELISA. Patients were divided into anti-HCV-positive (study group) and anti-HCV-negative (controls). Part II: A cohort study was performed with both groups followed from the time of transplantation to the present. Comparisons were made by t tests, chi-square analysis with Yates correction, Mann Whitney test for nonparametric results and multiple regression analysis. Part I: Anti-HCV was present in 76 of 716 sera assayed. There were no differences in sex, age, number of previous transplants, and underlying renal disease. Four variables predicted the presence of anti-HCV: number of blood transfusions; duration on dialysis; i.v. drug abuse, and nonwhite race. Part II: A group of 596 patients was further analyzed. The mean duration of follow-up was not different between the two groups. There were no differences in graft survival, overall mortality, or mortality secondary to liver disease or sepsis. Based on these results, the presence of anti-HCV should not be a contraindication for kidney transplantation.
