Filter by:This observational study will be conducted in patients with chronic co-infection with hepatitis B and D viruses, with negative PCR for HDV RNA in peripheral blood and no signs of active liver inflammation according to blood chemistry parameters, receiving background therapy with bulevirtide for more than 48 weeks and liver biopsy performed or prescribed to be performed as part of routine practice. After the patient has signed the Informed Consent, a portion of the liver biopsy collected as part of routine practice will be sent to the laboratory for PCR testing for HDV RNA, background therapy with bulevirtide will be interrupted, and the patient will be observed in the clinic in accordance with routine medical practice, but at least once times every 4 weeks, for timely detection of relapse of the hepatitis D and initiation of antiviral therapy. Once a relapse of viral hepatitis D is determined via the PCR HDV RNA, the patient's participation in the study will be terminated. The collected data will be analyzed to assess the probability of relapse-free over time. Separate tests will also be conducted for subgroups of patients based on covariates such as duration of previous background therapy with bulevirtide, duration of HDV suppression, use of any other concomitant antiviral therapy during bulevirtide treatment.
The aim is to assess the efficacy and specific safety in an observational study of patients with Chronic hepatitis D (CHD) with prospective follow-up, with antiviral treatment of 2 mg Bulevirtide (BLV) +/- PEG-IFNα-2a and +/- NA given as part of the patient's routine medical care. Also, explorative endpoints of biomarkers in peripheral blood, saliva, fecal sample and/or intrahepatic markers/signatures, and quality of life outcomes will be assessed.
The circulation of the Hepatitis D Virus (HDV) has considerably diminished in Italy, secondary to the control of the Hepatitis B Virus (HBV) with vaccination; this has led to the perception that HDV is vanishing and has reduced attention to the diagnosis of Hepatitis D. However, migratory fluxes from HDV endemic areas, fostered by labour-forces globalization, are increasingly reconstituting the reservoir of HDV in the country and hepatitis D has not yet vanished in native Italians but will remain an important medical issue for several years to come. As the epidemiologic and clinical features of HDV infection in migrant communities are largely unknown and the features of native Italians with long standing HDV infections have not been updated, this project intends to establish the contemporary epidemiological and medical context of HDV in immigrants in Italy and to determine the clinical characteristics and needs of the residual cohort of native HDV Italians, through the analysis of all HDV cases recruited in 12 months in a coordinated network of 35 Italian medical centers. The data will provide an appraisal of the burden of hepatitis D in the country and of its impact on the National Health System. They will present the paradigm of the current trend of HDV infection in high-income countries in the world.
Study is to 1. Understand the pattern of hepatitis delta screening among medical providers for Asian patients with chronic hepatitis B 2. Determine the proportion of Asian hepatitis B patients who have been screened and who have chronic hepatitis delta 3. Determine the pattern of hepatitis delta screening after education of medical providers on hepatitis delta
This is a multicenter, open-label, randomized clinical trial to Assess Efficacy and Safety of 3 Doses of Myrcludex B for 24 Weeks in Combination with Tenofovir Compared to Tenofovir Alone to Suppress HBV Replication in Patients with Chronic Hepatitis D
Ezetimibe possesses pharmacophore features to inhibit NTCP, the receptor required for HBV and HDV hepatocyte entry that include two hydrophobes and one hydrogen bond acceptor. Therapy with Ezetimibe may lead to decline in hepatitis D virus levels. The aim of the study is to evaluate the utility of Ezetimibe in patients with chronic HDV infection
The treatment of choice for chronic hepatitis D is uncertain. The investigators hypothesize that pegylated interferon (IFN) alfa-2b in combination with ribavirin (RBV) may be effective in the treatment of chronic hepatitis D patients who are also infected by hepatitis B virus (HBV). The purpose of this study is to test this hypothesis. The investigators will use pegylated IFN alfa-2b in combination with RBV for the treatment of patients with dual chronic hepatitis D virus (HDV) and HBV infection. A 24-week course of combination therapy pegylated IFN+RBV will be used.
Chronic hepatitis B is a disease of the liver caused by the hepatitis B virus. It affects nearly 1 million Americans. Approximately 25% of patients with chronic hepatitis B will develop liver cirrhosis and 5% of patients will develop liver cancer. Presently, two medications have been shown effective in the treatment of hepatitis B: lamivudine and alpha interferon. Alpha interferon (an antiviral drug that acts through the immune system) is given by injection once daily or three times a week for four to six months. Lamivudine (also known as 3-thiacytidine: 3TC) is an antiviral medication given as a pill once a day for twelve months. These treatments have been known to provide long-term improvement in one third of patients receiving them. In previous research, the drug lamivudine was shown to stop the growth of the hepatitis B virus and to lead marked decreases in the levels of hepatitis B virus and to improvements in the disease in 50 to 70% of patients. However, once lamivudine therapy was discontinued the virus returned to levels noted before the therapy began. In those studies lamivudine was given for 3 to 12 months then discontinued. This study will investigate the safety and effectiveness of long-term therapy with lamivudine. This study will select 60 patients diagnosed with hepatitis B. After a thorough medical examination and liver biopsy, subjects will be given lamivudine. The drug will be taken by mouth in tablet form (100 mg) once a day for up to 5 years. Subjects will undergo regular check-ups and after 1 year of therapy be admitted to the Clinical Center for another medical examination and liver biopsy to assess progress. Patients who have benefitted from the therapy will continue taking the medication for up to 5 years. A third liver biopsy will be done during the last year of treatment. The effectiveness of lamivudine will be determined by whether levels of hepatitis B virus decrease in the blood, whether liver enzymes improve, and whether inflammation and scarring decreases in the liver biopsies.
