A new antigen-antibody system was recently described in hepatitis B surface antigen (HBSAG(-positive sera. Despite indications of heterogeneity in specificity, the designations "e antigen" and "e antibodies" are used for the system as such in this articly. E'IGHT OF 17 long-term carriers of HBSAg with a histological picture of chronic persistent hepatitis or chronic aggressive hepatitis carried the e antigen, while none had demonstrable e antibodies in serum. Ten of 12 healthy carriers with e antibodies were blood donors who had donated 95 units of blood; none of these carriers was associeated with a reported case of posttransfusion hepatitis. In five individuals in the incubation stage of hepatitis B, e antigen appeared simultaneously with HBSAg but before the rise in transaminase levels. This finding further links e antigen to hepatitis B.

Serum alpha-fetoprotein levels were measured by radioimmunoassay in 473 patients with biopsy-proved noneoplastic hepatic disorders; 22% had values greater than 40 ng/ml, whereas only 1 of 350 patients with nonhepatic benign diseases had a value greater than this. Levels exceeded 40 ng/ml in more than 30% of patients with various types of hepatitis, and in 0% to 15% with inactive postnecrotic cirrhosis, primary biliary cirrhosis, biliary tract obstruction, and alcoholic liver disease. Values greater than 500 mg/ml were observed solely in viral subacute hepatic necrois. Only one patient had a level exceeding 3,000 ng/ml, the concentration at which alpha-fetoprotein is detectable by agar-gel diffusion. Of 75 patients with hepatoma, serum alpha-fetoprotein levels exceeded 40 ng/ml in 69%, and exceeded 3,000 ng/ml in 48%. These studies indicate that serum alpha-fetoprotein levels are elevated in several nonneoplastic hepatic disorders when a sensitive assay is used; this phenomenon may reflect hepatic regeneration.

Anicteric hepatitis, associated with fever and exfoliative dermatitis, developed in a diabetic patient two weeks after intake of a long-acting sulfonylurea, chlorpropamide (Diabinese). Granulomas showing heavy infiltration with eosinophils were found in the liver and bone marrow. These were interpreted as manifestations of an allergic reaction. The clinical signs, abnormal laboratory findings, and hepatic lesions subsided spontaneously on withdrawal of the drug. Bone marrow changes, however, persisted seven months after cessation of the drug. To our knowledge, this is the first report of a patient with liver and bone marrow inflammation characterized by granulomas with eosinophilic infiltration following intake of chlorpropamide.

Institutionalized patients with Down syndrome and matched controls with other causes of mental retardation were tested by immune adherence hemagglutination for the presence of antibody to hepatitis A antigen (anti-HA). Altogether 75.1% (175 of 233) exhibited presence of anti-HA, with no differences by sex or age. Patients reactive for hepatitis B surface antigen (HBsAg) or its antibody (anti-HBs) were reactive for anti-HA significantly more frequently than those with a negative reaction for these markers. In contrast to serologic markers of hepatitis type B, prevalence of anti-HA does not depend on the cause of mental retardation or on the age at primary infection. The rate of anti-HA positivity was found to be closely correlated with duration of institutionalization. The study confirmed that many closed institutions for the mentally retarded are hyperendemic for hepatitis type A and that formation of anti-HA is not greatly affected by either immune deficiency or immune immaturity.

Two episodes of acute viral hepatitis occurred in each of 34 patients. One episode in each patient was serologically diagnosable as type B hepatitis on the basis of tests for hepatitis B surface antigen or antibody. The other episode was classified as "non-B" on the basis of seronegativity, reinforced by seropositivity in an alternate bout. An epidemiologic background appropriate to "serum" hepatitis, either transfusion (one bout) or illicit self-injection (46 bouts), was associated just as frequently with serologically non-B episodes as with identified type B disease. The diagnosis of type B hepatitis, therefore, should be made only on the basis of serologic tests specific for hepatitis B virus infection. Other cases of sporadic diseases in adults must be labeled "viral hepatitis, type unspecifiable."

Two previously healthy adults with acute granulomatous hepatitis attributable to cytomegalovirus (CMV) monucleosis had prolonged fever, heterophil-negative lymphocytosis with numerous atypical forms, minor alterations in hepatic function, and evidence on biopsy, of a nonspecific acute hepatitis with granulomata. Infection with CMV was corroborated by a rising titer of complement-fixing antibody in case 1 and by a high titer of antibody that later fell in case 2. It is important to exclude CMV ivfection as an etiologic factor in cases of acute granulomatous hepatitis and fever of unknown origin.

A patient with primary herpes simplex virus (HSV) type 2 genital infection had dissemination in the 37th week of her first pregnancy. This was manifested by severe hepatitis, pancreatitis, and genital lesions. Temporary improvement followed the delivery of a healthy infant by cesarean section. Encephalitis became evident on the third postpartum day, and recovery was complicated by profound bradycardia, possibly due to viral myocarditis. Vidarabine was administered for seven days, and the patient survived with only mild neurologic sequellae. To our knowledge, this the fourth reported case of disseminated herpesvirus infection in pregnancy and the first due to HSV type 2. Pregnancy must be considered as a possible predisposing factor in dissemination of primary HSV infection.

Since 1961, viral hepatitis has been recognized as an occupational hazard among handlers of newly imported chimpanzees and other nonhuman primates. To determine whether previously reported cases were caused by human viral hepatitis type A, we tested paired serum samples from two outbreaks for antibody to hepatitis A antigen (anti-HA) by immune adherence hemagglutination (IAHA), recently available test. In both outbreaks, one of hepatitis transmitted from chimpanzee to man (Michigan, 1964), the second from chimpanzee to chimpanzee, man, and woolly monkey (Connecticut, 1971), serologic data documented recent hepatitis A virus infection among contacts-human and nonhuman primate-of implicated chimpanzees. This confirms serologically a previously noted epidemiologic association between nonhuman primate-associated hepatitis and human viral hepatitis, type A.

Nine episodes of a unique short-incubation form of hepatitis were observed during five years in six hemophilic children after infusion with commercial factor VIII concentrate prepared by two different manufacturers. Five patients with a single episode had no previous infusion for 14 months to 14 years. One patient with several episodes had no previous infusion for at least seven months preceding each episode. The illness was mild and self-limited. No seroconversions to cytomegalovirus, Epstein-Barr virus, toxoplasmosis, or hepatitis A virus occurred. Acute hepatitis B virus infection was also excluded. The findings suggest the presence of one or more non-A, non-B hepatitis agents associated with factor VIII concentrates.

Concomitant polymyositis diagnosed by muscle biopsy developed in a 51-year-old man with hepatitis B surface antigen (HBsAg) hepatitis. Findings from immunofluorescent studies showed deposits of gamma-globulins and complement in both muscle and liver. The HBsAg and HBsAg-antibody complexes were detected in the liver by immunofluorescence using fluorescein-labeled antibody to hepatitis Bs.
