Background: Approximately 600,000 deaths occur every year as a result of the acute and chronic consequences of hepatitis B virus infection. Ten different hepatitis B virus genotypes have been identified with distinct geographical distributions. Different clinical outcomes, including the rate of mutations, development of hepatocellular carcinoma, chronicity, response to treatment, transplantatio...

Despite the use of hepatitis B virus (HBV) vaccines and preventive measures, infection with HBV remains a major global health problem. Patients with chronic kidney disease (CKD) are at an increased risk of acquiring HBV infections from shared dialysis equipment, increased exposure to blood products, and immunodeficiency associated with CKD (1, 2). In addition, they may be more likely to develop...

This is a case report on a human immune deficiency virus (HIV) prevention trial participant who HIV seroconverted, developed hepatitis and rapidly progressed to acquired immunodeficiency syndrome (AIDS). A 24 year old HIV negative, non-pregnant participant consented to participate in the FEM-PrEP clinical trial. Her baseline parameters were normal; she was on oral contraception and was vaccinat...

Definitions. a) A matrix is called a complex matrix if all its entries are complex numbers. (In particular, any vector in C is considered a n× 1 complex matrix.) b) For any complex matrix A, we denote the matrix A T by A∗. c) Let U2 (C) be the group of all unitary 2× 2 complex matrices. In other words, let U2 (C) = { U ∈ GL2 (C) | U∗ = U−1 } . d) A complex matrix A is called Hermitian if it sat...

The incidence of cholangiocarcinoma, an aggressive malignancy with poor prognosis, is increasing. Hepatitis B and C have been well established as predisposing factors for this malignancy. availability efficacy treatment hepatitis infection has led to a substantial reduction in viral hepatitis-related cholangiocarcinoma mortality. Despite treatment, the potential developing continues exist patie...

 ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

Autoimmune hepatitis is a chronic hepatitis that occurs in children and adults of all ages. Diagnosis is based upon characteristic serologic and histologic findings and the exclusion of other forms of chronic liver disease. Guidelines issued by the AASLD suggest the following diagnostic considerations: The diagnosis should be made in patients with compatible clinical signs, symptoms, and labora...
