HDV Infection clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT04038372 Completed - HBV Infection Clinical Trials

Hepatitis D Virus Infection Among Hepatitis B Virus Surface Antigen Positive Individuals

Start date: November 2015
Phase:
Study type: Observational

Globally, about 248 million people are chronic HBV surface antigen carriers, and about 5% of them also had hepatitis delta virus (HDV) infection as well. The prevalence of HBsAg in Egypt is intermediate (2-7%) . Hepatitis D virus (HDV) is an incomplete RNA virus that needs hepatitis B surface antigen (HBsAg) to help its replication. HDV is considered a subviral particle because it depends on HBV for its propagation. Combined HDV- HBV infection produces more severe liver affection than HBV alone. HDV infection leads to both of acute and chronic liver illnesses. Acute HDV infection can occur at the same time with acute HBV infection (coinfection) or can be superimposed on the top of chronic HBV infection. About 20% to 30% of coinfections of HDV and HBV in humans develop fatal fulminant hepatitis versus 2% of patients with acute hepatitis B mono-infection. Worldwide, Hepatitis D virus (HDV) infection present in more than 15 million people and it is endemic in the Middle East . In Upper Egypt, data about the prevalence, clinical, laboratory and virological characters of Hepatitis D virus-infected patients is rare. This study aims were: 1. To estimate the prevalence of hepatitis D virus infection among HBsAg positive individuals. 2. To determine the clinical, laboratory and virological characters of HDV infected patients.
