Abstract

Human viral hepatitis results from a wide range of pathogens beyond the classic primary hepatotropic viruses such as hepatitis A-E. Neglected secondary hepatotropic viruses (HVs) such as human herpes viruses 6/7 (HHV-6, HHV-7), parvovirus B19 (B19V), bocavirus (HBoV) may cause hepatic injury ranging from mild to fulminant hepatitis. In the impaired immunological setting, such as in patients after solid-organ transplantation (SOT) or after hematopoietic stem cell transplantation (HSCT), they may have particular effects and result in prolonged and disseminated disease. Several candidate viruses remain to be investigated as possible liver pathogens, including torque-teno virus (TTV), SEN virus (SENV), human pegivirus (HPgV), and non-primate hepaciviruses (NPHV).

Given that Croatia has a high HSCT activity and one of the highest liver (32.20 pmp) and kidney (43.40 pmp) transplantation rates in the world, it would be of particular importance to investigate the impact of HVs in the context of transplantation outcomes.

This prospective study will include SOT (liver/kidney) and HSCT candidates in order to identify the prevalence of nine emerging and neglected hepatotropic viruses (HEV, HHV-6, HHV-7, B19V, HBoV, TTV, SENV, HPgV, NPHV) before and within the first year after transplantation by detection of viral DNA/RNA and specific antibodies. The explanted liver samples after LT will also be tested. It is important to note that secondary HVs are not included in routine diagnostic testing; therefore, no or scarce data exist regarding the epidemiology in the region. The study will define the epidemiology, clinical characteristics, and impact of hepatotropic viruses in the pre-and post-transplant setting to improve transplant outcomes. Detection and genetic characterization of new HVs will enable a better understanding of the epidemiology of viral hepatitis in Croatia and South-East Europe, which will set a platform to improve public health measures and post-transplant management and outcomes.
