Background Hepatitis E virus (HEV) infection is a significant public health problem in many parts of the world. The virus is classified into four major genotypes, representing a single serotype. HEV genotypes 1 and 2 are restricted to humans and usually transmitted via fecally-contaminated water, resulting in large outbreaks and epidemics of acute hepatitis in developing countries. HEV genotype...
Objective To describe the characteristics of hepatitis E virus (HEV) infection in a cohort of children from Upper Egypt using data from a large multicentre prospective study of acute viral hepatitis (AVH). Methods Data from subjects aged 2-18 years with AVH or close contacts of those with AVH found to have asymptomatic AVH were included in the analysis. Information concerning medical history, c...
Hepatitis E infection is usually a self-limiting disease. In industrialized countries, sporadic cases of acute hepatitis E virus (HEV) infections have been described; their number seems to be increasing in European countries. We report the first human case of autochthonous acute hepatitis E confirmed in Portugal. Patients with acute non-A-C hepatitis should be tested for HEV in Portugal and hep...
BACKGROUND AND AIMS The adverse effect of acute hepatitis A in chronic liver disease is well known. The outcome of acute hepatitis E in chronic liver disease has not been extensively studied. The present study aimed to examine the clinical profile and outcome of patients with chronic liver disease and hepatitis E virus (HEV) superinfection, and the seroprevalence of hepatitis A and E infections...
Introduction: Hepatitis E virus (HEV) is a fecal-oral transmitting virus which causes a chronic liver disease. ORF2 is an immunogen capsid protein of HEV that has been proposed to be used for Hepatitis E vaccine design. It is a 660-amino acid protein which includes an immunogenic region (residues 112-607). This protein has been expressed in complete and truncated forms, using different expressi...
Two hepatitis B core proteins bearing the immunodominant region of the hepatitis E virus (HEV) capsid protein, one at the C terminus of hepatitis B virus core antigen (HBcAg) and the other within the HBcAg immunodominant loop, were constructed. Both chimeric proteins exhibited HEV reactivity, but only the first construct retained HBcAg reactivity. The second construct was used to develop an ant...
Hepatitis E has a world-wide distribution and causes substantial morbidity and mortality in some developing countries, particularly among pregnant women. Hepatitis E virus (HEV) has recently been cloned and sequenced, and new diagnostic tests have been developed. These tests have been used to begin to characterize the natural history and epidemiological features of HEV infection. Experimental v...
To determine whether hepatitis E virus (HEV) is a cause of hepatitis among HIV-infected persons, we evaluated 1985-2009 data for US military beneficiaries. Evidence of acute or prior HEV infection was detected for 7 (4%) and 5 (3%) of 194 HIV-infected persons, respectively. HEV might be a cause of acute hepatitis among HIV-infected persons.

conclusions elevated aminotransferases in chb patients are most commonly caused by exacerbation of chb. nevertheless, when hbv dna is not elevated, other reasons should be excluded. amongst others, superinfection with another hepatotropic virus can be the reason for decompensation of chronic hepatitis b. this case report describes an asymptomatic hev superinfection followed by a flare in hbv re...
