Role of Cytokines in Hepatitis E Virus Infection During Pregnancy

The study will include pregnant women with acute viral hepatitis and fulminant hepatic failure (jaundice). The women with FHF will be recruited from the medical wards and antenatal wards as all such patients are routinely admitted in the hospital.

The pregnant women with acute viral hepatitis will be recruited either from antenatal clinic and medical outpatient, or from the medical and antenatal wards because pregnant women with AVH are admitted if they have serum bilirubin levels > 15- 20 mg / dl, persistently high bilirubin levels for more than 2-3 weeks, abnormal prothrombin time, evidence of progression of the disease, need parenteral therapy (because of excessive vomiting).

The enrolled subjects will be evaluated on the basis of a pre-designed and pre-tested proforma with respect to history and clinical examination, obstetrics examination and ultrasonography. Ten ml venous blood sample will be drawn from the patient at the time of enrollment detection of hepatotropic viruses (Various serological markers of hepatitis will be done which includes: IgM anti-HAV, HBsAg, IgM anti-HBc, HBeAg, anti-HCV Ab and IgM anti-HEV would be done using commercially available ELISA kits and Extraction of HEV-RNA from serum will be done) & levels of cytokines (IL-6, TGF-beta, IFN-g and TNF-α). All the subjects will be followed- up till delivery. The promoter region of cytokine gene will be amplified by PCR in appropriate reaction conditions using suitable sets of primers. PCR product will be used for studying the polymorphisms by restriction fragment length polymorphism.

The control group would comprise of age and POG matched healthy asymptomatic pregnant women

Follow up

All participants will be followed up till delivery for obstetrical complications, medical complications and pregnancy outcome.
