RT Journal Article SR Electronic T1 Unexplained abnormal liver function in patients with primary antibody deficiency: could it be chronic hepatitis E infection? JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 81 OP 83 DO 10.1136/jclinpath-2017-204627 VO 71 IS 1 A1 Mohamed, Omar E A1 Jones, Julie A1 Osman, Husam A1 Huissoon, Aarnoud P YR 2018 UL http://jcp.bmj.com/content/71/1/81.abstract AB Data from recent studies suggest rising incidence rate of hepatitis E virus (HEV) infection in the UK. HEV infection may take a severe and persistent course in immunocompromised patients, including transplant recipients on immunosuppressives, patients with HIV, haematological malignancies and in idiopathic CD4+ T lymphocytopenia. The prevalence of HEV in primary antibody deficiency (PAD) disorders is still unknown. The aim of this study was to investigate HEV infection in 27 patients with PAD with unexplained, persistently elevated liver enzymes. Although all the 27 patients tested negative for HEV-RNA, we would still strongly recommend that HEV should be considered in any immunodeficient patient with impaired liver function.
