Hepatitis E virus (HEV) is responsible for major outbreaks of acute hepatitis in developing countries where it was first described as a waterborne disease, transmitted by drinking water contaminated with feces. Attention was focused on HEV in developed countries and its associated diseases in recent years as a result of increasing reports of autochthonous(More)
Hepatitis E virus (HEV) strains from rabbits indicate that these mammals may be a reservoir for HEVs that cause infection in humans. To determine HEV prevalence in rabbits and the strains' genetic characteristics, we tested bile, liver, and additional samples from farmed and wild rabbits in France. We detected HEV RNA in 7% (14/200) of bile samples from(More)
We screened plasma samples (minipools of 96 samples, corresponding to 53,234 blood donations) from France that had been processed with solvent-detergent for hepatitis E virus RNA. The detection rate was 1 HEV-positive sample/2,218 blood donations. Most samples (22/24) from viremic donors were negative for IgG and IgM against HEV.
BACKGROUND & AIMS Hepatitis E virus (HEV) infection can evolve to chronic hepatitis in immunocompromised patients. Pegylated α-interferon can effectively treat chronic HEV infection after liver transplantation but is contraindicated for kidney transplantation. We assessed the antiviral effect of ribavirin monotherapy in patients with chronic HEV infection(More)
Hepatitis E virus is an emerging concern in immunocompromised patients, who may become chronically infected. This prompted us to assess the performance of two anti-HEV IgG and IgM assays for diagnosing acute HEV infections. The specificities of the assays were estimated by testing samples from 2 to 3 year-old French children and blood donors and their(More)
Infections with hepatitis E virus (HEV) in solid-organ transplant recipients can lead to chronic hepatitis. However, the incidence of de novo HEV infections after transplantation and risk for reactivation in patients with antibodies against HEV before transplantation are unknown. Pretransplant prevalence of these antibodies in 700 solid-organ transplant(More)
BACKGROUND On 11 December 2013, 3 clustered cases of hepatitis E were reported on a French coastal island. Individuals had taken part in a wedding meal that included a spit-roasted piglet. The piglet had been stuffed with a raw stuffing partly made from the liver. Investigations were carried out to identify the vehicle of contamination and evaluate the(More)
Southwest France is a highly endemic region for hepatitis E virus (HEV). This study examined the circulation of HEV strains between 2003 and 2014 in the Midi-Pyrénées, and compared these data with those from the rest of France. The polyproline region (PPR) of the ORF1 region of the HEV genome was also analyzed. HEV genotype was determined by sequencing a(More)
Genotype 3 hepatitis E viruses (HEVs) are distributed across the world and are now considered to be an emerging public health concern in industrialized countries. At least 10 genotype 3 subtypes have been identified in humans and animals worldwide. It was recently reported that the sensitivities of HEV RNA assays differ greatly. We have assessed the(More)
We assessed the performance of the Ceeram and Altona assays, the first two commercially available hepatitis E virus (HEV) RNA assays, using serial dilutions of 4 HEV-positive reference samples (genotypes 3a, 3c, 3e, and 3f). Both assays provided good analytical sensitivity and high reproducibility for detecting genotype 3 HEV RNA.
