A case/control study of patients with primary hepatic carcinoma (P.H.C.) and their families was carried out in Dakar, Senegal. 28 P.H.C. cases were matched by age,sex, and ethnic group with 28 controls. Serum was collected from cases, controls, parents (28 mothers, 27 fathers) of cases, parents of controls, 71 siblings of cases, and 58 siblings of controls. Assays of their sera for hepatitis-B surface antigen (HBsAg), antibody to HBsAg (anti-HBs) and antibody to hepatitis-B core antigen (anti-HBc) produced the following results. (1) Nearly all P.H.C. cases (97%) and controls (93%) had some evidence of infection with hepatitis-B virus (H.B.V.), but the cases were more likely to be anti-HBc(+) and less likely to be anti-HBs(+) than the controls. (2) Most of the mothers of the cases were HBsAg(+) (71%), whereas only 14% of the mothers of controls were HBsAg(+). Lover titres of anti-HBs were less common in the mothers of the cases. (3) None of 27 fathers of cases had detectable anti-HBs, but 13 (48%) of the fathers of controls were anti-HBs(+). (4) Siblings of the P.H.C. cases were more likely to have anti-HBs than either their sibs with P.H.C. or the sibs of the controls. However, sibs of P.H.C. cases had lower titres of anti-HBs than the sibs of the controls. These data are consistent with the hypothesis that the P.H.C. cases were infected with H.B.V. by their mothers and that there was an environmental factor which affected the immunological response of all family members to H.B.V. Infection with H.B.V. and the mode of response to that infection among members of families appear to be major factors in the aetiology of P.H.C. in West Africa.

Infections with hepatitis A and B viruses are common in all parts of the world and constitute a major public health problem. The identification of specific antigenic markers of these viruses has led to the development of sensitive laboratory tests. These, in turn, have resulted in a better understanding of the epidemiology, pathogenesis, immunology, and the nature of these common infections. In the case of hepatitis type B, laboratory tests revealed a persistent carrier state of the surface antigen in some 120-175 million people and established the significance of hepatitis B virus in the pathogenesis of serious chronic liver disease, including a strong association with primary hepatocellular carcinoma in tropical and some subtropical regions. In addition, the specific diagnosis of hepatitis types A and B has revealed a previously unrecognized form of hepatitis which is clearly unrelated to either type. This new form of infection of the liver is now the most common type of hepatitis after the transfusion of blood and blood products in some areas of the world and it also appears to be an important cause of sporadic hepatitis, particularly among adults.

Serial determinations of HBeAg and anti-HBe were made in sera of 155 selected patients with acute hepatitis B who were followed up for one to four years. In the early phase of hepatitis, HBeAg was present in 43 cases (27.7%) and anti-HBe in 12 cases (7.7%). Evaluation of the outcome of hepatitis showed that development of chronic hepatitis occurred in 11 out of 43 HBeAg positive patients, in 10 out of 100 HBeAg negative patients (P = less than 0.05) and in 2 out of 12 patients carrying anti-HBe. Nine out of 11 HBeAg positive chronic subjects showed persistent HBe antigenemia over two months, while the remaining 32 patients, who recovered completely, lost HBeAg within two to three weeks from the onset of the disease. These data suggest that the prognostic value of HBeAg in acute hepatitis patients may be taken into account when HBeAg persists in the serum and that anti-HBe does not invariably protect from the development of chronic hepatitis.

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 study was performed to establish the value of immune adherence haemagglutination tests for antibody to hepatitis A virus in the diagnosis of non-B hepatitis. Infection with hepatitis A virus was confirmed in 14 out of 16 patients from six families and seven out of nine patients in whom the source of infection was unknown. One additional patient, who had had two episodes of jaundice, was shown to have had an attack of hepatitis A followed by an attack of hepatitis B. In patients with acute hepatitis A antibody detectable by immune adherence haemagglutination becomes detectable three or four weeks after the onset of symptoms and reaches peak levels about five weeks later.

Infection of mice with the JHM strain of mouse hepatitis virus causes demyelination as a result of a cytolytic infection of oligodendroglia. In recovery, animals show remyelination, which could result either from surviving oligodendrocytes extending their territory or by generation of new oligodendroglia. Electron microscopic autoradiographic studies with 3H-labeled thymidine demonstrate that the cells associated with remyelination are newly generated oligodendroglia.

The natural incidence of the etiologically distinct types of viral hepatitis was determined by investigating acute phase sera of symptomatic hepatitis cases occuring in the Hannover area in 1975 for the presence of hepatitis B surface antigen, antibodies to hepatitis A, hepatitis B core and surface antigens, and by measuring the IgM serum levels. Fourteen different seroepidemiologic patterns were recognized. Although there was a high prevalence of hepatitis A antibody in the population, the frequency of hepatitis A was low (n = 56) suggesting that the hepatitis A virus does not play a major role in symptomatic hepatitis in the Hannover area at present. Spread of the hepatitis A virus was mostly associated with person-to-person contact or tourist travel in southern Europe. Hepatitis B was the predominant type of hepatitis (n = 211). Hepatitis non-A, non-B was observed infrequently (n = 62). A high percentage of patients with hepatitis B and hepatitis non-A, non-B reported parenteral exposure to potentially contaminated materials. No other findings, however, suggested an infectious etiology of hepatitis non-A, non-B.

Immune serum globulin prophylaxis for foreign travellers should be reserved for those at high risk having no immunity against hepatitis A. In this study from Sweden the incidence of tourist hepatitis in different age groups was correlated to the prevalence of antibodies to hepatitis A virus (anti-HAV) in the population. 58% of individuals over 50 years had anti-HAV and travellers in these ages seldom experienced "tourist hepatitis". In younger age groups a low prevalence of anti-HAV (11%) was combined with a higher incidence of tourist hepatitis.

The etiology of 72 episodes of liver disease that developed in 62 of 162 renal-transplant recipients was evaluated. Infection with hepatitis B virus was a minor problem, and none of our patients had evidence of infection with hepatitis A. Cytomegalovirus infection was ubiquitous in the population and probably accounted for many episodes of acute liver disease. This agent's role in causing chronic hepatitis is less secure. Infections with other viruses including Epstein-Barr virus, adenovirus, and the herpes viruses were only rarely associated with hepatic disease. Azathioprine was responsible for some episodes of acute cholestasis but could not be incriminated as a direct cause of chronic disease. A cause could be identified for the majority of episodes of acute hepatic dysfunction, but the cause of most of the chronic hepatitis remains undetermined. It is likely that infection with non-A, non-B hepatitis virus accounts for much of this serious, often fatal, complication of renal transplantation.

Indications, selection of donor and recipient, medical and surgical management and complications, problems of organ procurement. Renal transplantation has become routine therapy. Organs are predominantly obtained from cadavers, transplantations from living donors are rarely indicated. Advances in preservation methods have improved organ quality and prolonged storage time. Selection of the most suitable recipient is based on histocompatibility matching. Blood transfusions before transplantation seem to improve the results. Recognition of a rejection crisis is primarily based on clinical symptoms. Persistent rejection calls for prompt explantation and the patient has to return to dialysis. Infections, serum-hepatitis and gastro-intestinal bleeding are the most common complications. Late complicatons are diabetes mellitus, cirrhosis of the liver, osteopathy, recurring glomerulonephritis, and, rarely, malignomas. Transplantation frequency in the Federal Republic of Germany could be increased by more awareness of physicians and a better knowledge of the general public about the need for cadaver donors.
