Background/aims: It is still controversial whether the human GB virus-C can cause liver injury, as in situ demonstration of the virus is still inconclusive.
Methods: Here we describe the case report of a patient with two episodes of severe acute hepatitis, who had a meticulous clinical, immunological and microbiological work-up, including human GB virus-C RNA detection by in situ hybridization and electron microscopy.
Results: Human GB virus-C viraemia was found as the only potential cause of hepatitis in this patient. Furthermore, virus-like particles could be demonstrated in the cytoplasm of single hepatocytes by electron microscopy and human GB virus-C RNA was detected in the liver by in situ hybridization.
Conclusion: The presence of human GB virus-C RNA in serum together with the demonstration of human GB virus-C RNA in the liver, favour acute human GB virus-C infection as the cause of liver injury in this patient. Thus virus-like particles and hepatic human GB virus-C RNA should be specifically looked for by electron microscopy and in situ hybridization, especially during the diagnostic work-up of patients with unexplained hepatitis.

Human pegivirus (HPgV) is transmitted through sexual or parenteral exposure and is common among patients receiving blood products. HPgV is associated with lower levels of human immunodeficiency virus (HIV) RNA and better survival among HIV-infected patients. This study aimed to investigate the prevalence of HPgV and determine its subtypes in HIV-infected individuals living in Istanbul, which has the highest rate of HIV infection in Türkiye.

Background: Hendra virus is an emerging virus with a geographically broad host reservoir. In humans, Hendra virus causes excessive inflammatory disease of the lung and nervous system. Our current understanding as to how Hendra virus or what factors induce inflammation is limited and as such, there are currently no therapeutic options available for patients who contract Hendra virus.
