Background and purpose: Hepatitis B virus (HBV) is a major global health problem. The prevalence of HBV infection varies throughout regions of the world. More than 350 million people live with chronic HBV infection and many different clinical symptoms are associated with it. Long-term complications of HBV infection lead to cirrhosis of the liver and hepatocellular carcinoma. Consequently, 0.5-1...
SIR, We read with interest the article by Yang et al. in a recent issue of the Journal in which they retrospectively reviewed patients with pemphigus vulgaris and dermatomyositis treated with immunosuppressive therapies including systemic glucocorticosteroid (GC). In the article, the authors suggested that four of 98 patients had developed hepatitis because of GC-induced hepatitis B virus (HBV)...
A new assay was developed for the detection of hepatitis B virus (HBV) in human serum using amplification of a short viral DNA sequence by means of the polymerase chain reaction. As little as 0.4 fg viral DNA, corresponding to about 130 genome equivalents, per ml serum could be detected after the amplification procedure. This assay detected viral DNA in a number of patients with proven or suspe...
BACKGROUND To determine clinical-pathologic variables in patients with a new diagnosis of hepatocellular carcinoma (HCC) and underlying hepatitis B vs. C infection. METHODS Patients presenting to a single urban hospital with a new diagnosis of HCC were entered into a clinical database. Variables including number and size of tumors, presence of metastases, serum alpha-Fetoprotein, hepatitis se...
This study estimated the incidence of viral hepatitis in children treated for cancer, to identify variables that could affect this incidence and to assess the role of hepatitis B virus (HBV) vaccination in preventing infection. Between September 2007 and June 2008, 256 children in the haemato-oncology unit at the Children's Welfare Teaching Hospital, Baghdad, were studied prospectively. Demogra...
We retrospectively investigated the characteristics, patterns of disease progression, outcome and difficulties in the management in 11 patients with concurrent autoimmune hepatitis (AIH) and HBV or HCV infections (5 HCV and 6 HBV including 2 with HDV co-infection) since there are scarce data on this issue. HCV or HBV diagnosis preceded that of AIH in all patients by many years. At initial clini...
Hepatocellular carcinoma (HCC) is one of the most aggressive cancers worldwide and is associated with the high rates of morbidity and mortality. α-fetoprotein (AFP) is common used in diagnosis of HCC; however, a growing body of research is questioning the diagnostic power of AFP. There is, therefore, an urgent need to develop additional novel non-invasive techniques for the early diagnosis of H...
We estimated prevalence and incidence of liver condition outcomes, and costs to the health service of diagnosed hepatitis B virus (HBV) in Tayside, UK. HBV patients were identified from electronic virology data between 1989 and 2003. The health resource costs of HBV for surface antigen-positive (HBsAg+) patients and HBV (HBsAg+ or immune, i.e. recovered) patients were calculated. A total of 633...
Chronic hepatitis B virus (HBV) infection increases the risk of developing primary hepatocellular carcinoma (HCC); about one million people die from HBV-related diseases annually. Development of new strategies for the diagnosis and treatment of chronic HBV infection is important. In a case-control study to identify markers in the HBV genome that can be associated with HCC development, the compl...
background: in patients who are hepatitis b virus (hbv) dna-positive, but hbv surface antigen (hbsag) -negative, the infection is referred to as occult hepatitis b infection (obi). occult hbv infection is harmful when other liver diseases are present, and can aggravate liver damage in in patients with chronic liver diseases. in human immunodeficiency virus (hiv) infection the suppression of vir...
