The presence of antibodies to hepatitis E virus (HEV) was studied among hemophiliacs, blood donors, and hepatitis patients. Four of 296 (1.4%) hemophiliacs and 5 of 1,275 (0.4%) donors were confirmed as positive for HEV antibodies (difference was not significant: P = 0.07). Parenteral transmission of HEV to hemophiliacs was thus rare or nonexistent. Seven of 187 hepatitis patients were found with HEV antibodies (IgG and IgM). Six persons fell ill shortly after arriving from HEV-endemic countries. The seventh patient, without a history of travel, represents a case of nontropical hepatitis E. Consequently, hepatitis E should be considered in patients suffering from acute non-ABC hepatitis, even in industrialized countries.

Infection with an identified hepatotrophic virus accounts for 13-50% of acute liver failure (ALF) in Europe, and an additional 16-17% of cases have non-A non-B or indeterminate hepatitis in whom a viral aetiology is presumed. Hepatitis C is rarely responsible for acute liver failure in Europe and North America but accounts for a higher proportion of cases in Japan, and hepatitis E may lead to ALF, particularly in pregnant women. The survival in cases of acute liver failure associated with hepatitis A is 70%, whereas less than 30% of those with non-A non-B hepatitis survive without a transplant. Management depends on intensive care support and careful selection of patients likely to benefit from transplantation. Recurrence of hepatitis A and non-A non-B hepatitis has been reported following transplantation for ALF, and hepatitis B recurs less frequently in these circumstances than after transplantation for chronic infection.

Sera from 1274 patients were tested for IgG antibodies to hepatitis E using the newly developed Abbott Enzyme immunoassay (EIA). All tested patients had previously proved to be negative for hepatitis A, B, and C. 180 suffered from hepatitis, in the remaining 1094 the hepatitis tests were done for other reasons (presurgical, pregnancy etc.). No clear-cut distinction was found between positive and negative sera in the Abbott ELISA: Therefore the cut-off value was set somewhat higher than as stated by the producer. Thus, 15 (8.3%) of the hepatitis patients and 25 (2.3%) of the remaining patients were positive. Epidemiological data were available from 12 positive patients. Seven had been in countries endemic for hepatitis E, however 5-all Austrian citizens-had never visited such an area. These data can be explained either by unspecific (false) positive tests or by endemic occurrence of hepatitis E in Austria, which, however, seems unlikely.

Sera from two groups of patients in Nepal with acute hepatitis were examined for the presence of antibodies to the hepatitis A, B, C, and E viruses to determine the etiology of viral hepatitis. The first group consisted of 43 consecutive acute hepatitis patients presenting at a clinic for tourists and foreign residents in Kathmandu from January 1987 to June 1988. The other group consisted of 95 consecutive acute hepatitis patients admitted during the same period at a hospital used predominantly by adult Nepalese residents of Kathmandu. Hepatitis A was diagnosed in 39 (91%) of the foreign patients and in one of the 95 Nepalese patients, whereas hepatitis E was diagnosed in four of the 43 foreign patients and in 90 (95%) of the Nepalese patients. No cases of hepatitis B or C were identified in either group, nor were any cases of dual infection with the hepatitis A virus (HAV) and hepatitis E virus (HEV) identified. These results suggest that in the Kathmandu Valley, hepatitis A is the predominant form of hepatitis among foreigners, hepatitis E is the predominant form of hepatitis among adult Nepalese, and both HAV and HEV are endemic to the Kathmandu Valley.

Israel is endemic for hepatitis E virus (HEV), the causative agent of enteric non-A, non-B hepatitis. Transmission is via the feco-oral route but the possibility of transmission through blood transfusion has been raised. This question was addressed by examining sera from 188 hemophilic patients in Israel, screening was performed with an enzyme immunoassay (EIA) for antibody against hepatitis E virus (anti-HEV) and confirmed with a neutralization test. Sixteen patients (9%) were seropositive for anti-HEV. A statistically significant difference was not found between the seroprevalence in this group and that of a healthy Israeli control population, matched for sex and age. The anti-HEV-seropositive hemophiliacs had the same seroprevalence of antibodies to hepatitis B and C virus and to HIV and the same number of cases with chronic hepatitis as among the anti-HEV-seronegative patients. The seroprevalence of antibodies to hepatitis A virus (anti-HAV) was, on the other hand, higher in the anti-HEV-seropositive group. This study indicates that HEV is not transmitted by cryoprecipitate or lyophilized factor concentrates. High prevalence of coinfection with hepatitis A supports our conclusion that HEV infection in Israeli hemophiliacs was due mainly to feco-oral transmission.

Hepatitis E virus (HEV) is the causative agent of non-A, non-B hepatitis which is transmitted by the fecal-oral route and occurs principally in the form of large epidemics and outbreaks in developing countries. Two overlapping synthetic peptides corresponding to overlapping DNA sequences of the ORF 3 of HEV genome were found to be immunoreactive with sera from patients involved in two epidemics of enterically transmitted non-A, non-B hepatitis. The results suggested the existence of two distinct epitopes. The four synthetic peptides representing these two epitopes from Burma and Mexico strains of hepatitis E virus, were used to investigate anti-HEV reactivities. HEV antibodies were detected in 84-88% of HEV-infected individuals according to the peptide used. The results suggest that a peptide-based ELISA can provide an accurate tool for the diagnosis of acute hepatitis type E.

Sporadic non-A, non-B hepatitis is the most common indication for liver transplantation in patients presenting with fulminant and subacute liver failure. This study used serological, histological, and molecular biological techniques to examine specimens from 23 consecutive patients transplanted for sporadic non-A, non-B hepatitis. No evidence was found of hepatitis C virus, hepatitis E virus, or 'cryptic' hepatitis B virus infection.

Hepatitis E virus (HEV) is the cause of enterically transmitted non-A, non-B (NANB) hepatitis. Water-borne epidemics have been reported in many developing countries primarily affecting young and middle-aged adults. To determine the role of HEV in acute sporadic NANB hepatitis, we have studied the profiles of anti-HEV IgG in the sera of patients previously diagnosed for NANB hepatitis. We tested the sera of 53 patients with acute NANB hepatitis and 100 healthy people as a control group for anti-HEV IgG. Thirty-nine of the 53 patients (73.3%) and none of the control group were positive for HEV infection, according to results shown by ELISA. This result suggests that HEV is a common cause of acute sporadic NANB hepatitis in Turkey. Further studies are needed in the other regions to determine the true prevalence of HEV infection in Turkey.

Hepatitis C virus (HCV) and hepatitis E virus (HEV) are the principal causes of non-A, non-B hepatitis worldwide, and in Turkey one-third of the cases of acute hepatitis are non-A, non-B. To explore the epidemiology of HCV in Turkey (including the association of HCV with HEV), a seroprevalence study of HCV was conducted. Sera from residents from five distinct regions of the country were tested for antibodies to HCV (anti-HCV) and HEV (anti-HEV). Anti-HCV was detected in 21 (1.5%) of 1,374 persons and was more common in residents over 54 years of age (p = 0.02), with less than primary education (p = 0.013), more than two children (p = 0.003), and who lived in the regions of Ayvalik (p = 0.046) or Trabzon (p = 0.038) compared to Istanbul. Anti-HCV was marginally associated with anti-HEV, which was found in 5.9% of residents. However, this association was lost after controlling for age and education (p = 0.225). HCV infection occurs in all regions of Turkey and is more common in persons who are older and of low socioeconomic status. As resources permit, efforts to reduce the transmission of HCV in Turkey (such as screening blood donations for anti-HCV) are indicated.

The association between viral hepatitis and pregnancy is not common, nevertheless it has been described that hepatitis is the most frequent cause of jaundice in pregnant women. In this article the current knowledge on the perinatal repercussions of the different types of viral hepatitis are reviewed. Hepatitis A is rare during pregnancy and is not associated with perinatal risk. Hepatitis B virus (HBV) can be transmitted transplacentally, 20 per cent of the children infected by this route will develop liver cirrhosis or carcinoma in the adult age, so the infants of HBsAg carrier mothers must be immunized at born. The perinatal transmission of hepatitis C virus has been proved but the repercussion in the fetus or newborn is unknown. Hepatitis D virus can only be transmitted from mother to child together with HBV. Hepatitis E has been associated with a mortality of 10 to 40 per cent in pregnant women.
