Clinical Manifestations of Hepatitis E

Area of Science:

• Hepatology
• Infectious Diseases
• Virology

Background:

• Clinical manifestations of Hepatitis E (HEV) resemble other viral hepatitis types.
• While typically self-limited, HEV can cause severe illness, including fulminant hepatic failure, in pregnant women and those with chronic liver disease.
• Chronic HEV infection predominantly affects organ transplant recipients; most cases are asymptomatic.

Purpose of the Study:

• To summarize the diverse clinical presentations of Hepatitis E infection.
• To highlight the varying severity and outcomes across different patient populations.
• To identify areas requiring further investigation, such as extrahepatic manifestations.

Main Methods:

• Literature review of clinical presentations of Hepatitis E.
• Analysis of HEV infection outcomes in specific demographics (pregnant women, transplant patients, neonates).
• Identification of common and uncommon symptoms, including jaundice, fatigue, abdominal pain, fever, and ascites.

Main Results:

• Acute HEV is usually self-limiting but can be severe in certain groups.
• Neonatal HEV infection shows diverse clinical signs and biomarkers.
• Chronic HEV is rare outside of organ transplant recipients; asymptomatic cases are common.

Conclusions:

• Hepatitis E exhibits a wide spectrum of clinical manifestations.
• Specific populations like pregnant women and transplant recipients are at higher risk for severe HEV.
• Extrahepatic manifestations and complications of HEV warrant additional research.
