Acute viral hepatitis in pregnancy

To describe the clinical outcome of pregnancy and vertical transmission of acute viral hepatitis in pregnancy. Forty-eight pregnant patients with acute viral hepatitis were evaluated clinically and by abdominal ultrasonography. Serological studies for hepatitis markers were performed using radioimmunoassay. The results were evaluated using Student's t-test and tests of proportion. Thirty-five (72.9%) delivered live birth babies at term, while 13 (27.1%) had fetal complications and/or losses. The percentage of fetal complications and/or losses was higher in patients who had non-A, non-B hepatitis (30.8%) than those who had type B hepatitis (25%). The most common fetal complication was premature delivery (14.9%) followed by stillbirth and abortion (8.3%) for each. The overall percentage of vertical transmission of hepatitis B virus was 2 out of 27 (7.4%). Acute viral hepatitis carries a high risk for both mother and fetus. Routine vaccination of all susceptible women and babies against hepatitis B is recommended in endemic areas.

Aetiology and outcome of acute viral hepatitis in pregnancy

The aetiologic types of sporadic acute viral hepatitis in 169 pregnant women were compared with those of 70 non-pregnant women and 287 adult men. The majority of pregnant women (87.6%) came with acute hepatitis in the last trimester of pregnancy. Non-A, non-B (NANB) hepatitis accounted for 81.6% of hepatitis during pregnancy in comparison with 48.6% in non-pregnant women and 57.1% in adult men. Hepatitis A was extremely uncommon during pregnancy. Hepatitis B infection accounted for 17% of all cases in pregnant women compared with 45% in controls. Acute viral hepatitis in pregnancy had a poor outcome as assessed by maternal and/or fetal mortality (28.5%). The outcome was equally bad in hepatitis NANB and hepatitis B. Pregnant women generally had significantly lower immunoglobulin levels in comparison with non-pregnant women. In acute NANB hepatitis during pregnancy, serum IgG and IgM levels were lower and higher, respectively, compared with those in non-pregnant women and pregnant women with acute hepatitis B. It is suggested that an immune suppression during pregnancy might be responsible for increased susceptibility to acute NANB viral hepatitis, which, by itself, seems to induce only a transient acute phase IgM response.

Viral hepatitis and pregnancy in Kuwait

The frequency and severity of viral hepatitis among pregnant and non-pregnant women in Kuwait was studied from 1980 to 1984. 542 female hepatitis patients were investigated, of whom 52 (9·6%) were pregnant. 35 of the 52 (67·3%) cases of viral hepatitis in pregnancy were due to hepatitis B virus while 11 of 52 (21·2%) and 6 of 52 (11·5%) had acute hepatitis non-A, non-B (NANB) and hepatitis A virus infections, respectively. The frequency and severity of viral hepatitis among the pregnant women was similar to that among non-pregnant women. Hepatitis did not have a deleterious effect on pregnancy and no death was recorded. Fulminant acute NANB hepatitis was seen in only one patient, who recovered completely.

Incidence and severity of viral hepatitis in pregnancy

A prospective field study was carried out during an epidemic of non-A non-B hepatitis for determining the incidence and severity of hepatitis in pregnant women, nonpregnant women of child bearing age and men (15 to 45 years old). In 36 (17.3 percent) of 208 pregnant women viral hepatitis developed, as compared to 71 (2.1 percent) of 3,350 nonpregnant women and 107 (2.8 percent) of 3,822 men. The incidence of disease in pregnant women was higher than in the two control groups. The incidence of viral hepatitis in the first, second and third trimesters was 8.8 percent, 19.4 percent, and 18.6 percent, respectively. The incidence in all three trimesters was higher, when compared to that in nonpregnant women. In eight pregnant women (22.2 percent) with viral hepatitis, fulminant hepatic failure developed, as compared to its occurrence in three men (2.8 percent) and in no nonpregnant women. This significantly increased incidence of fulminant hepatitis in pregnancy was indicative of a greater severity of hepatitis during pregnancy. Increased susceptibility to fulminant hepatitis was observed exclusively in the last trimester. Nonfulminant viral hepatitis did not influence the course of pregnancy or fetal well-being. Fetal loss in fatal fulminant hepatitis was a consequence of maternal death and could not be ascribed to direct effect on the fetus or pregnancy.

Viral Hepatitis in Pregnancy: Problems for the Clinician Dealing with the Infant

Stokes and colleagues first described transmission of hepatitis B virus (HBV) infection from a mother who was an HBV carrier to an infant born by cesarean section in 1954. Evidence of clinical hepatitis with jaundice, detected at 2 months of age, was later complicated by chronic active hepatitis. The infant died at 18 months of age with advanced cirrhosis of the liver. In the past decade tests have been developed that are specific for hepatitis B antigens and antibodies and they have enabled physicians to identify acute hepatitis B infection during pregnancy, as well as the presence of a chronic carrier state. Thus it has been possible to assess the effect of maternal HBV infection on the newborn infant. The attack rate of HBV infection in infants has been reported to range between 10% and 70%. Infection is usually detectable by 1 to 3 months of age. Although most infections are asymptomatic, fulminant hepatitis is seen on rare occasions. Of major significance is the tendency for the infected infants to become chronic HBV carriers with possible progression to chronic active hepatitis, cirrhosis, and rarely hepatoma. Hepatitis A virus (HAV) infection has not been a problem in the newborn. Hepatitis A is now an uncommon infection among adults in Western countries while in developing areas it is primarily a disease of childhood.
