The eight genotypes of hepatitis B virus (HBV) have different geographical distributions, virological characteristics, and clinical manifestations. A unique subtype of HBV genotype A (HBV/A) was reported in sub-Saharan Africa, raising the possibility that patients infected with this subtype (HBV/Aa ["a" for African and Asian]) may have different clinical outcomes than other HBV/A isolates (HBV/...
The discovery of novel antivirals to treat hepatitis B virus (HBV) infection is urgently needed, as the currently available drugs mainly target viral proteins at replication step, whereas host factors also play significant roles in HBV infection. Although numerous studies have reported candidate for treatment, there remains a need find new drug that may other steps life cycle. In this study, by...
چکید ه سابقه و هدف رایج ترین مارکر مورد استفاده جهت تشخیص عفونت hbv در اهداکنندگان خون، غربالگری hbsag است که عدم شناسایی آن، به عللی مانند دوره پنجره، موتاسیون در ژن s و یا کاهش ساخت این ag ، ممکن است در گیرندگان این فرآورده ها ایجاد بیماری نماید. از آن جایی که شیوع anti-hbc در جمعیت ها با شیوع hbsag متناسب است، بنابراین لازم است در مناطقی با شیوع بالای hbv ، مطالعه هایی در زمینه ارزیابی ش...
Hepatitis B virus (HBV) recurrence after liver transplantation for HBV-associated liver diseases results in decreased patient and graft survival. Herein we have reported two cases of HBV recurrence following relapse of hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT). Both cases had LDLT for end-stage liver disease secondary to HBV infection with nodules of HCC exc...
Epidemiological data on hepatitis delta virus (HDV) infection in Belgium are lacking. A multicenter questionnaire-based registry on HDV infection was collated between March 1, 2008 and February 28, 2009. It consisted of patients coinfected with hepatitis B virus (HBV) and HDV. The data samples were compared to those of a concurrent registry on HBV infection. Prospective data of patients with HB...
UNLABELLED Occult HBV infection is characterized by the persistence of HBV DNA in the liver of individuals negative for HBV surface antigen (HBsAg). Occult HBV may exist in the hepatocytes as a free genome, although the factors responsible for the very low viral replication and gene expression usually observed in this peculiar kind of infection are mostly unknown. Aims of this study were to inv...
مقدمه: سیروز جبران نشده ناشی از هپاتیت مزمن B باعث کاهش چشمگیری در بقای این بیماران می شود.تجویز اینترفرون آلفا به این بیماران ممنوع است چندین مطالعه اثربخشی لامی وودین را در کاهش علائم ناشی از این عدم جبران نشان داده اند. هدف: هدف از انجام این مطالعه تعیین اثر لامی وودین برروی عملکرد کبدی و وضعیت بالینی مبتلایان به سیروز جبران نشده ناشی از HBV مراجعه کننده به مرکز حمایت بیماران کبدی یابستری...
During previous studies of susceptibility to hepatitis B virus (HBV) infection, HBV DNA was detected in 2/6 wild-caught baboons. In the present study, HBV DNA was amplified from 15/69 wild-caught baboons. All animals were negative for HBV surface antigen and antibody against HBV core antigen. Liver tissue from 1 baboon was immunohistochemically negative for HBV surface antigen but positive for ...
AIM To describe the characteristics of people diagnosed with acute and chronic hepatitis B virus (HBV) infection in British Columbia (BC). METHODS We used data from the BC Hepatitis Testers Cohort (BC-HTC), which includes all individuals tested for hepatitis C virus (HCV) or human immunodeficiency virus (HIV) or those diagnosed with HBV or active tuberculosis in BC since 1990. These data were...
Hepatitis D, also referred to as hepatitis D virus, or delta virus (HDV) is considered be a subviral satellite because it can propagate only in the presence of B (HBV) (WHO, 2020). There are uncertainties about epidemic patterns HDV infection and its contribution burden liver disease. defective that completes life cycle with (HBV). The HBV super-infection has been one most severe forms chronic ...
