BACKGROUND Serum hepatitis B virus (HBV) DNA and hepatitis B e antigen (HBeAg) liver function in patients with chronic hepatitis B (CHB) are significantly associated. A comparison of clinical significance of fecal HBV DNA and serum HBV DNA has not yet been reported. MATERIAL AND METHODS Stool and serum samples were collected from 66 patients with CHB. Fecal HBV DNA, serum HBV DNA, and intestina...
introduction: occurrence of detectable amounts of viral antigen or viral particles in the blood of infected patients with hepatitis b virus (hbv) is a significant characteristic of hbv infection. detection of hbv antigen or its dna among individuals of a community is a crucial factor to know the burden of hbv infection. hepatitis b surface antigen (hbsag) is a suitable marker of hbv infection b...
Spontaneous preterm birth is the leading cause of perinatal morbidity and mortality. In this study the spontaneous preterm birth rates in a group of hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV)-infected pregnant women without known risk factors for preterm delivery as well as the role of maternal laboratory data and hepatitis B surface antigen/HBV deoxyribonucleic acid...
Background: In spite of available, and sensitive screening assay for detection of hepatitis B virus surface antigen (HBsAg), occasional cases of post-transfusion hepatitis B virus infection are still observed. The aim of the present study was to assess the prevalence of positive anti hepatitis B core (anti-HBc) and presence of HBV-DNA in serum sample of healthy blood donors negative for both HB...
BACKGROUND There is no standard management of reactivation of hepatitis B virus (HBV) infection in HBV-resolved patients without hepatitis B surface antigen (HBsAg), but with antibodies against hepatitis B core antigen and/or antibodies against HBsAg (anti-HBs). METHODS We conducted a prospective observational study to evaluate the occurrence of HBV reactivation by serial monthly monitoring o...
Hepatitis B virus (HBV) infection remains a global public health challenge with an estimated 257 million people in 2015 living as chronic carriers. Sub-Saharan Africa has the second largest burden of these carriers HBV infection. Children sickle cell anemia (HBSS) are prone to recurrent blood transfusion attendant risk blood-borne diseases including hepatitis There several studies Nigeria on pr...
The presence of hepatitis B virus (HBV) DNA in extrahepatic tissues has been well documented. Whether HBV DNA can persist in extrahepatic tissues for long periods of time in the absence of replication in the liver has not been determined previously. Recently, two patients with end-stage liver disease secondary to chronic active HBV were treated with baboon liver xenotransplants as these animals...
Background: Entecavir (ETV) has been widely used in the clinical treatment of Hepatitis B Virus (HBV). However, whether ETV is helpful recovery T cell immune function remains unclear. Objectives: We aimed to assess effects on serum HBV-DNA, interferon-γ (IFN-γ), and pregenomic RNA (pgRNA) patients with infection. Methods: The data 300 HBV admitted from January 2017 2019 were retrospectively ana...
چکیده مقدمه: عفونت نهفته هپاتیت B شکلی بالینی از هپاتیت B است که در آن فرد بهرغم HBsAg منفی، HBV-DNA در خون محیطی دارد. هنوز علت اینکه این دسته بیماران قادر به پاکسازی کامل ویروس از بدن نیستند به طور کامل مشخص نشدهاست. به نظر میرسد تفاوتهای ژنتیک و ایمونولوژی در این مورد سهم عمدهای داشته باشند و از جمله مواردی که پاسخ ایمنی علیه ویروسها را تغییر میدهد سیستم سیتوکین است. IL-4 سیتوکینی ا...
BACKGROUND Detection of human hepatitis B virus (HBV) DNA in the urine of patients with chronic hepatitis B infection (CHB) has been reported previously, suggesting urine could provide a potential route of horizontal HBV transmission. However, it is not clear whether the HBV DNA detected in urine is indeed full-length, infectious viral DNA. The aim of this study is to assess the potential infec...
