The epidemiologic, clinical and laboratory features of 40 adults with acute viral hepatitis type B were compared with those of 40 adults with hepatitis non-B. Overall, the clinical presentations were remarkably similar and the etiology could not be determined in individual cases. An exception to this was that all post-transfusion cases in this series were affected by hepatitis B. Men predominated in both the hepatitis B and non-B groups. There was a tendency to seasonal clustering in summer/autumn in both groups. Hepatitis B patients were significantly older and 59% of them had a history of possible parenteral exposure during the six months preceding admission. On the other hand 76% of patients with hepatitis non-B had no apparent parenteral exposure. Dental treatment, injections and contact with jaundiced patients were recorded in both groups and were therefore of no value in determining the exact etiology in individual cases. Fever was more common in hepatitis non-B, while the onset of the disease was insidious and afebrile in 80% of patients with hepatitis B. As a group, patients with hepatitis B had more extensive liver injury and a more prolonged clinical course, and the only fatality was in this group. Cholestatic features were rare and extrahepatic immune complex disease was extremely uncommon in both hepatitis B and non-B.

Thirty-five Black patients with cirrhosis of the liver were admitted to the professorial unit over a 1-year period and were included in a carefully planned prospective study. Men predominated over women in a ratio of 3:1. Alcohol consumption in the form of African beer was significantly higher in cirrhotic patients than in a control population. The clinical picture was neither predominantly that of alcoholic nor of cryptogenic cirrhosis. Hepatomegaly, porphyria cutanea tarda, ascites, splenomegaly and oesophageal varices were common. There was a complete absence of gynaecomastia, spider naevi and liver palms. Histologically, the majority of patients had macronodular cirrhosis, and only 1 patient had micronodular cirrhosis and minimal fatty change. Hepatitis B surface antigen (HbsAg) was not detected in any patient, despite a positive HbAg rate of 4% in Black African blood donors, determined by means of the same laboratory technique.

Following the clinical observation that there appeared to be an association between shigellosis and male homosexuality, the medical records of 113 patients at The New York Hospital were reviewed retrospectively. Of the 38 males studied who were between the ages 19 and 61, seventeen were homosexual (44-7 per cent.). Only one of the matched controls was homosexual. Of the men with shigellosis who had a history of foreign travel, 10 per cent. were homosexual; however, among the patients without a travel history, 57-1 per cent. were homosexual (P less than 0-05). For male patients with shigellosis who do not have an appropriate travel history, the physician should expand his epidemiological investigation to include sexual contacts. Men and women who perform rectal intercourse should be cautioned to abstain from this activity until their stool cultures are negative for shigella. If a male patient with shigellosis is homosexual, he should be screened for other sexually transmitted diseases such as syphilis, gonorrhoea, hepatitis B, and amoebiasis.

In 1983, the regulation on reporting transmissible diseases was extended. At that time, the doctors were obliged to report all cases of acute viral hepatitis to the Cantonal physician. The Federal Office of Health commissioned a statistical evaluation of the reports from the years 1984 to 1987. Of the 4543 reports analysed, 40% relate to hepatitis A, 47% to hepatitis B and 7% to non-A non-B hepatitis. Men suffered hepatitis more frequently than women, with the exception of the non-A non-B hepatitis, where the sexes are roughly equally represented. Adolescents and young adults are the most frequently affected age group for all types of hepatitis. Those dependent on drugs have a particularly high risk of infection for all types of hepatitis. The cases of hepatitis occurring after journeys abroad are even more significant in terms of numbers. The medical personnel can no longer be regarded as a high-risk group. An age-standardized comparison shows that, with regard to hepatitis B, the risk for men in medical professions is the same as the average risk for all men, while the risk for women is still slightly higher than that for the female population as a whole.

Hepatitis B immunisation has been offered to staff of Hampstead Health Authority since 1982 and is now offered to all staff with clinical contact. Three doses of 20 micrograms of vaccine are given at zero, one, and six months and the antibody response is measured three months later. Results were analysed to seek for associations with the antibody response. At the time of analysis, 2739 people had started vaccination and 1067 had completed the course and had a measurement of antibody response. Vaccine injections were initially into the buttock and later into the arm; measurement of antibody levels was initially by radioimmunoassay (RIA) and later by enzyme immunoassay (EIA). A positive antibody response was defined as a positive/negative ratio of greater than 10 for RIA or a level of greater than 10 mIU/ml for EIA. Associations between antibody response and other variables were tested by chi 2 and a multiple logistic regression analysis was undertaken to examine the effects of variables in combination. The overall antibody response rate was 95%. Men and women did not respond differently but there were significantly more positive responses with the EIA testing method and a tendency for more positive responses with arm injections. The responders were significantly younger than the non-responders and had significantly lower values of body mass index (wt/ht2).(ABSTRACT TRUNCATED AT 250 WORDS)

We examined the associations between seropositivity for hepatitis B virus (HBV) with the presence or development of antibodies to human immunodeficiency virus (HIV-1) and with HIV-1 induced T-helper lymphocyte deficiency or acquired immunodeficiency syndrome (AIDS). Serologic data on HBV and HIV-1, cytometric enumeration of CD4+ lymphocytes, clinical events (AIDS by Centers for Disease Control criteria) and hepatitis B vaccination histories were available on 4,498 homosexual participants in the Multicenter AIDS Cohort Study, Men were classified as to previous infection with HBV and prevalent or incident infection with HIV-1. Although there was an association between seropositivity for HBV infection and HIV-1 infection at enrollment (odds ratios anti-HBc 2.6; HBsAg 4.2), the relation between HBV seropositivity and subsequent seroconversion to HIV-1 was weaker (odds ratios 1.3 and 1.6). HIV-1 seroconversion was also associated with a history of certain other sexually transmitted diseases, but predisposing sexual practices did not account for the association between HBV and HIV-1 infection. Seropositivity for HBV infection at entry was not related to initially low or more rapid subsequent decline in T-helper lymphocyte counts and was not associated with an increased incidence of AIDS during 2.5 years of follow-up. History of vaccination against HBV did not appear to decrease susceptibility to HIV-1 infection or to subsequent progression of immunodeficiency. We conclude that prior HBV infection is unlikely to be specifically associated with acquisition of HIV-1 infection and is unrelated to more rapid progression of HIV-1-induced immunodeficiency.

Between 1978 and 1980, 359 hepatitis B seronegative homosexual and bisexual men were recruited from the San Francisco municipal sexually transmitted disease clinic for hepatitis B vaccine trials. Of the 359 participants, 320 (89%) consented to have their stored blood samples tested for human immunodeficiency virus antibodies. The prevalence of human immunodeficiency virus infection in these 320 vaccine trial participants rose from 0.3% in 1978 to 50.9% in 1988. The annual incidence of human immunodeficiency virus infection showed that seroconversion peaked in 1980-1982, dropped significantly in 1983, and has remained low. Men less than 30 years old on entry into the study seroconverted earlier in the epidemic and had higher incidence rates than men 30 years or older (p = 0.07). No statistical difference in seroconversion rates was found for other demographic variables. Using a Kaplan-Meier survival curve of the cumulative proportion of men without acquired immunodeficiency syndrome by duration of human immunodeficiency virus infection, an estimated 39% (95% confidence interval 27%-51%) will develop acquired immunodeficiency syndrome within 9.2 years of infection. Cox proportional hazard stepwise analysis showed no correlation between age at seroconversion, race, or year of seroconversion and progression to acquired immunodeficiency syndrome.

Previous studies from this laboratory support the view that increased serum ferritin levels are associated with an increased risk of primary hepatocellular carcinoma (PHC). We have tested this hypothesis in a population of Korean patients with chronic liver disease followed for development of PHC. Serum ferritin levels were measured over time in 249 patients with liver diseases (mostly chronic) followed for 2 to 17 years in Seoul, Korea. Most of the patients were chronically infected with hepatitis B virus. During the first 8 months of follow-up, there were no cases of PHC and no deaths. During this same period, no patient had a serum ferritin level initially below 300 ng/ml and rising above 300 ng/ml, but some patients with ferritin levels above 300 ng/ml experienced decreases to below 300 ng/ml. Therefore, patients were grouped by ferritin level during the first 8 months of follow-up into 3 categories according to the above criteria. Multivariate analysis showed that consistently elevated ferritin levels (category 3) were significantly associated with the development of PHC. Men were more likely to have elevated ferritin levels than women and were at higher risk of developing PHC. Men who were chronically infected with HBV and had ferritin levels above 300 ng/ml had a 50% chance of developing PHC during the follow-up period, compared with a 20% risk of PHC for men with lower ferritin levels (categories 1 and 2). This elevated risk of PHC in men with elevated ferritin levels was confined to the first 3 years of follow-up.

A randomized, double-blind clinical trial of plasma-derived and DNA recombinant hepatitis B virus vaccines was conducted in 186 homosexual men. Nine months after the immunization series (three doses) began, the seroconversion rate in the plasma vaccine group was 88% (68/77); this was significantly higher than the 74% (60/81) response rate of the recombinant vaccine group. Men positive for antibody to the human immunodeficiency virus (HIV) had a considerably higher nonresponse rate to either vaccine than expected in non-HIV-infected homosexual men. The odds ratios of nonresponse to hepatitis B virus vaccine for HIV-seropositive vs HIV-seronegative subjects were 12.0 (95% confidence interval, 1.7 to 89.3) and 13.6 (95% confidence interval, 2.3 to 148.3) for the plasma and DNA recombinant vaccines, respectively.

In order to assess the frequency and profile of cirrhosis in the young, 169 consecutive patients with cirrhosis were studied. Sixty three (37%) patients of less than or equal to 35 years age were defined as young and the remaining 106 (63%) patients (greater than 35 years) as adult cirrhotics. Men predominated significantly (p less than 0.01) in the young cirrhotic group. The aetiology, the frequency of positive hepatitis B markers and initial clinical presentation were similar in the two groups. During the follow up period (30.6 +/- 29.7 months for the young and 25.8 +/- 21.7 months for the adult group), except for abdominal distension and pedal oedema which occurred significantly more often in the adult compared with the young cirrhotics, no difference was noted in the two groups. Twenty seven (39.7%) deaths (40% as a result of hepatic failure and 52% due to variceal bleeding) occurred in the young and 47 (44.3%) deaths (63.8% because of hepatic failure and 26% because of variceal bleeding) occurred in the adult cirrhotics during the follow up (difference NS). The five year survival (61.9% v 55.7%) and the probability of survival within the same Child's grade of liver disease were comparable. In both the groups, however, the probability of survival was significantly higher in Child's A compared with Child's B and C and in Child's B compared with Child's C grade of liver disease. Survival was not influenced by sex of the patient and aetiology of cirrhosis. Results of this prospective study indicate that cirrhosis is not uncommon in young adults. The aetiology, clinical presentation, natural history of the disease and the survival rates in young cirrhotics do not differ significantly from adult cirrhotics.
