Filter by:The main objective of this study is to evaluate the prevalence and the clinical impact of Orthohepevirus C infection in different human populations, and to determine its zoonotic origin comparing the sequences obtained in both human and animal populations. This is an ambispective study where Orthohepevirus C infection will be evaluated in four high risk human population: i) patients with acute hepatitis, ii) patients with positive IgM antibody against Hepatitis E virus infection with undetectable viral load, iii) HIV infected individuals, and iv) solid organ transplant recipients. Furthermore, we will analyze three animal populations: i) suburban rodents, ii) domestic rodents, iii) wild carnivores. Viral sequences identified in both human and animal populations will be compared to evaluate the zoonotic origin of the infections.
Adult patients with chronic hepatitis B and cirrhosis of any etiology who are found to have suspected liver cancer are potentially eligible for the study. All enrolled patients will undergo two MRI scans using two different contrast agents. The type of contrast agent for the 1st MRI will be performed using hepatocyte-specific contrast agent. The participant will undergo the 2nd MRI using extracellular contrast agent. The MRI examinations will be independently interpreted by two different radiologists. The radiologists will evaluate focal hepatic lesions and categorize them according to the LI-RADS v2018 and EASL 2018. Once the diagnosis is made, the participants will be provided with the standard of care. After the initial treatment, the participants will be followed up with multi-phasic dynamic contrast-enhanced CT every 3 or 6 months for at least 2 years. Based on the prospectively written radiology reports, the diagnostic performances will be calculated and compared between MRI with hepatocyte-specific contrast agent and MRI with extracellular contrast agent, using the pathology and clinical criteria as the reference standard.
