Clinicopathologic features and pathologic diagnosis of hepatitis E.

Area of Science:

• Hepatology
• Virology
• Pathology

Background:

• Hepatitis E virus (HEV) is a leading cause of acute hepatitis worldwide.
• HEV infection presents as endemic/epidemic waterborne disease in resource-poor settings and as a zoonosis from meat consumption globally.
• While often mild, HEV can cause severe disease in pregnant women, cirrhosis patients, and chronic infection in immunocompromised individuals.

Purpose of the Study:

• To review current knowledge on Hepatitis E virus pathology.
• To discuss the implications of HEV localization studies for diagnostics.
• To outline the spectrum of histologic changes in HEV infection.

Main Methods:

• Review of HEV localization studies.
• Analysis of histologic findings in HEV infection across different clinical scenarios.

Main Results:

• HEV infection exhibits distinct localization patterns relevant to diagnostics.
• A spectrum of histologic alterations is associated with HEV infection.
• Understanding HEV pathology remains limited despite its global health impact.

Conclusions:

• Further research into HEV pathology is crucial.
• Localization studies and histologic analysis aid in understanding and diagnosing HEV infection.
• Addressing knowledge gaps in HEV pathology is essential for managing its global health burden.
