Long-term outcome of hepatitis delta in different regions world-wide: Results of the Hepatitis Delta International Network.

Background And Aims: Chronic hepatitis delta represents a major global health burden. Clinical features of hepatitis D virus (HDV) infection vary largely between different regions worldwide. Treatment approaches are dependent on the approval status of distinct drugs and financial resources.

Clinical long-term outcome of hepatitis D compared to hepatitis B monoinfection.

Background And Aims: Hepatitis D virus (HDV) infection causes the most severe form of chronic viral hepatitis. However, it is still unclear to what extent the underlying cirrhosis may contribute to disease progression. The aim of this study was to compare the long-term outcome of HDV infection with HBV monoinfection in a single-center cohort of both non-cirrhotic and cirrhotic patients.

Ten-year follow-up of a randomized controlled clinical trial in chronic hepatitis delta.

Hepatitis delta virus (HDV) infection causes the most severe form of viral hepatitis. PEG-interferon alpha-2a (PEG-IFNα-2a) is the only effective treatment but its long-term clinical impact is unclear. The aim of this study was to investigate the long-term outcome after 48 weeks of pegylated interferon alpha-2a therapy.

Soluble immune markers in the different phases of chronic hepatitis B virus infection.

Chronic hepatitis B virus (HBV) infection may follow four different consecutive phases, which are defined by virology as well as biochemical markers and differ in terms of prognosis and need for antiviral treatment. Currently, host responses reflected by immune markers are not considered in this definition. We aimed to study soluble immune markers and their distribution in different phases of chronic HBV infection.

Treatment strategies for patients with decompensated liver cirrhosis due to hepatitis C virus infection eligible for liver transplantation: real-life data from five German transplant centers.

Background: Even with highly effective direct-acting antivirals (DAAs) treatment of patients with decompensated hepatitis C (HCV) cirrhosis remains challenging. Clinical deterioration and the need for liver transplantation (LT) may arise despite previous antiviral treatment. It is unclear whether in patients with high Model for End-Stage Liver Disease (MELD) antiviral treatment is too risky and should thus be deferred until after LT.

Dose-dependent impact of proton pump inhibitors on the clinical course of spontaneous bacterial peritonitis.

Background & Aims: Spontaneous bacterial peritonitis is a severe complication in patients with cirrhosis leading to acute kidney injury, hepatic encephalopathy and a high mortality. In this study, we aimed to investigate the impact of proton pump inhibitors and the potential relevance of the taken dosage on the incidence and clinical course of spontaneous bacterial peritonitis.

Methods: Overall, 613 consecutive patients with decompensated cirrhosis were included.

Clinical and virological heterogeneity of hepatitis delta in different regions world-wide: The Hepatitis Delta International Network (HDIN).

Background & Aims: Chronic hepatitis D (delta) is a major global health burden. Clinical and virological characteristics of patients with hepatitis D virus (HDV) infection and treatment approaches in different regions world-wide are poorly defined.

Methods: The Hepatitis Delta International Network (HDIN) registry was established in 2011 with centres in Europe, Asia, North- and South America.

Antiviral therapy of hepatitis delta virus infection - progress and challenges towards cure.

Hepatitis B-/D-virus co-infection causes the most severe form of viral hepatitis, frequently leading to liver cirrhosis, hepatic decompensation and consecutive liver-related mortality. Treatment options for hepatitis delta are limited. The only recommended therapy is pegylated interferon alpha which leads to virological responses in about 25-30% of patients.

Antiviral treatment and liver-related complications in hepatitis delta.

Unlabelled: Hepatitis delta virus (HDV) is the most severe form of viral hepatitis. Pegylated interferon alfa (PEG-IFNα) is effective in only 25%-30% of patients and is associated with frequent side effects. The aim of this study was to analyze the clinical long-term outcome of hepatitis delta in relation to different antiviral treatment strategies.

Non-invasive fibrosis score for hepatitis delta.

Background & Aims: Identifying advanced fibrosis in chronic hepatitis delta patients and thus in need of urgent treatment is crucial. To avoid liver biopsy, non-invasive fibrosis scores may be helpful but have not been evaluated for chronic hepatitis delta yet.

Methods: We evaluated eight non-invasive fibrosis scores in 100 HDV RNA-positive patients with available central histological reading.

Anti-HDV IgM as a marker of disease activity in hepatitis delta.

Background: Hepatitis delta frequently leads to liver cirrhosis and hepatic decompensation. As treatment options are limited, there is a need for biomarkers to determine disease activity and to predict the risk of disease progression. We hypothesized that anti-HDV IgM could represent such a marker.
