Hepatitis E autochthonous infection in chronic liver disease.Eur J Gastroenterol Hepatol. 2008 Aug; 20(8):800-3.EJ
Hepatitis E virus is endemic in many parts of the developing world and causes a self-limiting hepatitis in young adults, except in pregnant women and patients with chronic liver disease, where the mortality is high. Locally acquired hepatitis E is increasingly recognized in the developed world. It is caused by hepatitis E virus genotype 3, affects the middle-aged and the elderly, and may be a zoonotic infection from pigs. We present a case of locally acquired hepatitis E infection in a patient with previously undiagnosed cirrhosis, which resulted in subacute liver failure and death. We describe our attempt to trace this infection to a free-range pig farm adjacent to the patient's place of employment. Hepatitis E infection should be considered in the differential diagnosis in patients with decompensated chronic liver disease whatever their age or travel history. When found, the prognosis may be poor.
