| Popis: | Hepatitis E is an emerging disease in developed countries and is usually asymptomatic, particularly in children. Chronic infection is possible in immunocompromised individuals. In the context of a liver transplant, it can simulate a rejection. In this case, antiviral therapy may be considered, thus highlighting the need to diagnose hepatitis E virus (HEV) infection in this population.Given the lack of data in France, we have studied the the prevalence of antibodies to HEV in the paediatric liver transplant population.This was a retrospective study, carried out in Lyon between 1st January 2010 and 31 May 2013. HEV serology (anti-HEV IgMIgG) and HEV PCR were studied in 96 children who had undergone liver transplants (84 isolated liver and 12 combined liver and kidney transplants).Eight patients (8.3%; 62.5% girls; mean age:12.3 years) were HEV seropositive. The mean period since their transplantation was 10 years (range:2-21.8 years). Biliary atresia was the principal indication for transplantation. Seven of these eight children had received liver transplants. There were no differences between the epidemiological and clinical data concerning these patients and the remainder of the study population, particularly with respect to immunosuppression(7/8 tacrolimus; 50% dual immunosuppression). No cases of chronic hepatitis E were found, but 1/8 had chronic cytolysis(EBVadenovirus infection). In all the patients tested(4/8), seroconversion had occurred after the transplant. There was no significant differences between the age groups in this study.This study showed that in France, the prevalence of antibodies to HEV in paediatric liver and combined liver and kidney transplant patients is 8.3%, as has been found by other European authors. |
