Viral Hepatitis in Pregnancy--A study of its Effect on Maternal and Foetal Outcome.

BACKGROUND AND AIMS: The outcome of Hepatitis during pregnancy has been observed to be widely different by various authors, ranging from the benign to fatal. A poor outcome has increasingly been observed in pregnant women suffering from Hepatitis in Central India. Hence, this study was undertaken to study the incidence, causative organisms and chief prognostic factors affecting the outcome of viral hepatitis in pregnant women. METHODS: Sixty-eight pregnant women reporting to the hospital with jaundice were enrolled as cases and their Haematological, Biochemical and Viral profiles were studied. Sixteen non- pregnant women were enrolled as controls and a similar workup was done. A comparison was done between the two groups We also divided the cases into two groups--survivors and non- survivors and tried to find out the factors predicting mortality. The unpaired student t test and chi square test were used to find out whether the differences were statistically significant. RESULTS: Viral Hepatitis in pregnancy caused a very high maternal mortality (19.1%) and foetal wastage (42.6%). Hepatitis E virus was the commonest causative organism (77.9%) responsible for viral hepatitis during pregnancy. It also caused the highest maternal mortality due to fulminant hepatic failure. Maternal mortality was significantly higher in those women presenting with features of encephalopathy, SIRS, high bilirubin levels and prolonged prothrombin time. Vertical transmission was noted in Hepatitis B and E. CONCLUSIONS: Hepatitis E is the chief causative organism causing fulminant hepatic failure in pregnant women in Central India. It lead to very high rates of maternal mortality and foetal wastage.

Acute liver failure in pregnancy: causative and prognostic factors.

BACKGROUND/AIMS: Acute liver failure (ALF) in pregnancy is often associated with a poor prognosis. In this single-center observational study we aim to study the incidence, causes, and factors affecting mortality in pregnant women with ALF. PATIENTS AND METHODS: Sixty-eight pregnant women reporting with clinical features of liver dysfunction were enrolled as "cases." Their clinical course was followed and laboratory studies were performed. The presence of ALF was defined as the appearance of encephalopathy. The results were compared with a "control" group of 16 nonpregnant women presenting with similar complaints. The cases were further subdivided into two groups of "survivors" and "nonsurvivors" and were compared to find out the factors that contribute to mortality. RESULTS: ALF was seen in significantly more number of pregnant women than the controls (P = 0.0019). The mortality rate was also significantly higher (P = 0.0287). Hepatitis E virus (HEV) caused jaundice in a higher number of pregnant women (P < 0.001). It also caused ALF in majority (70.3%) of pregnant women, but HEV infection was comparable between the survivors and nonsurvivors (P = 0.0668), hence could not be correlated with mortality. CONCLUSIONS: Pregnant women appear to be more susceptible for HEV infection and development of ALF. The mortality of jaundiced pregnant women increased significantly with appearance of ALF, higher bilirubin, lower platelet count, higher international normalized ratio, and spontaneous delivery.
