    Virtual ICE-HBV Workshop On Serum Biomarkers Session 2

    12:00 pmZoom

    ICE-HBV is organizing an virtual and interactive workshop on HBV biomarkers endorsed by the International HBV Meeting. The event is aimed at scientists, clinicians, pharmaceutical and diagnostic industry representatives.  The workshop, chaired by Anna Kramvis and Peter Revill, is put together by the ICE-HBV serum biomarkers working group. Both classic and future biomarkers will be discussed. The workshop will lead to a consensus statement on promising serum biomarkers. 

    The workshop will be divided in two sessions, held on Monday Oct 5 and Monday Oct 12, 2020, via Zoom. Both sessions will start at 12PM GMT, go for approximately 2.5 hours each, and will be recorded. More information here.

    Free registration is open here.

    Biomarkers of HBV cccDNA expression + Q&As

    See Abstract

    Title: Biomarkers of HBV cccDNA expression  Date of presentation: October 12th, 2020  Authors: Maura Dandri  Affiliation: Research Group Viral Hepatitis, Center for Internal Medicine, University Medical Center Hamburg-Eppendorf (UKE), Hamburg, Germany  Abstract Body:  Chronic hepatitis B virus infection cannot be completed eliminated due to the persistence of the covalently closed circular (cccDNA), the template of HBV transcription in infected hepatocytes. Since assessment of cccDNA amounts and activity requires an invasive procedure, there is an urgent need for serum biomarkers that can accurately correlate with cccDNA expression in the liver. Different types of HBV serum biomarkers have been proposed, which include classical markers, such as HBsAg, and newer markers such as HBV RNA and core related antigen. However, their function, events that may affect their production and clinical relevance in chronic HBV infection is not fully understood. This presentation will focus on the cccDNA as producer of HBV serological biomarkers, giving emphasis on how distinct therapeutic approaches may affect the levels of virological markers, in particularly HBV RNA in serum, and to which extent such changes can provide information about the amounts and activity of intrahepatic cccDNA. Current gaps of knowledge, caveats and open questions will be discussed.

    Biomarkers of Occult HBV infection  + Q&As

    See Abstract

    Title: Biomarkers of Occult HBV infection  Date of presentation: Oct 12, 2020  Authors: Teresa Pollicino  Affiliation: University Hospital of Messina, Italy  Abstract Body:  Occult HBV infection (OBI) is defined as the presence of replication-competent HBV DNA (cccDNA) in the liver and/or HBV DNA in the blood of people who test negative for HBsAg. Intrahepatic HBV DNA is the gold standard diagnostic biomarker for OBI. However, liver tissue is not always available, and there is no standardized assay. A more common (but less sensitive) approach to diagnose OBI is the detection of HBV DNA in the blood. Because serum HBV DNA is usually present in low concentrations and may only be intermittently detected in OBI, analyzing serially collected blood samples, and testing DNA extracts from no less than 1 ml of serum/plasma is recommended for OBI diagnosis. Anti-HBc may be used as a surrogate marker to identify OBI in blood/organ donors and people who will receive immunosuppressive therapies.  However, the absence of anti-HBc does not rule out OBI.

    Biomarkers of liver cancer  +Q&As

    Title: Biomarkers of Liver Cancer

    Date of presentation: October 12, 2020

    Author: Patrizia Farci, MD

    Affiliation: Hepatic Pathogenesis Section, Laboratory of Infectious Diseases, NIAID, NIH

    Abstract Body:

    HCC is the seventh most common human cancer and the second leading cause of cancer-related death globally. HBV is the leading cause of HCC worldwide. The prognosis of HCC is poor and, as a result, the incidence and mortality rates are roughly equivalent. The complexity of HCC is rarely seen in other cancers, and the lack of early diagnostics and effective treatments has made this cancer one of the most challenging. Patients with cirrhosis are at highest risk for developing HCC. The current surveillance strategies in high-risk populations using ultrasound imaging with or without serum alpha-fetoprotein (AFP) are suboptimal for the early detection of HCC, which is critical for a better prognosis. Although a series of HCC biomarkers are under clinical evaluation, including novel biomarkers derived from Omic technologies, their clinical validation is still in the early phases. Only AFP has completed the 5 phases required for routine clinical use, but there are limitations with its sensitivity and specificity. In my presentation, I will discuss the current state of HCC surveillance, the present challenges, and the areas of future research.

    Point of Care Testing - an unmet and urgent need + Q&As

    See Abstract

    Title: Point of Care Testing- an unmet and urgent need Date of presentation: October 12, 2020 Authors: Daryl Lau, MD, MPH Affiliation: Harvard Medical School Abstract Body: Current access to HBV care is suboptimal in the resources limited settings. The inaccessibility of diagnostic tests poses an obstacle for effective HBV screening and treatment programs. There is an urgent need for reliable and affordable point-of-care (POC) tests that can be applied to provide the best quality of care within available resources.  A comprehensive and practical HBV management guidance applying such POC tests to meet the acceptable health standards and prepare the health systems to adapt to the evolving hepatitis B treatment advances is essential in the resources limited settings.

    Major Research Interest: The overall aim of his research is focused on understanding the evolutionary background and molecular mechanism involved in infectivity, persistence and neutralization of hepatitis B and D viruses. In the past, he discovered and characterized a new species of hepatitis delta-like viruses and various hepadnaviruses from mammals, including hepadnaviruses from primates, bats and shrews that could serve as animal models for HBV and HDV. He is also interested in HBV vaccines and analysed efficiency of neutralising antibodies against HBV surface proteins. During the last years, D. Glebe has devoted substantial parts of his research to the understanding of processes that constitute current genetic diversity, infectivity and pathogenicity of hepatitis B viruses, hepatitis D viruses and related animal viruses.
