background viral hepatitis is a systemic infection affecting the liver predominantly. almost all cases of acute viral hepatitis are caused by one of five viral agents: hav, hbv, hcv, hdv and hev. the present study aimed to find out the frequency of various forms of viral hepatitis (hav, hbv, and hcv), route of transmission, the history of vaccination against hepatitis b, and clinical findings i...
hepatitis b virus (hbv) infection is the 10th leading cause of death worldwide. the most important diagnostic and screening marker for hbv infection is hepatitis b surface antigen (hbsag), and the most widely used hbsag screening test is enzyme-linked immunosorbent assay (elisa). in this study, an elisa assay has been developed for detection of hbsag using two novel monoclonal antibodies (mab) ...
background to evaluate the strength of association and to determine the best prediction of response in terms of sensitivity and specificity among quantitative baseline hbv-dna levels in blood serum in patients with chronic hepatitis b (chb) infection who treated with interferon-alpha-2b. patients and methods totally, 78 chb patients with serum hbv-dna>105 copies/ml were treated with interferona...
viral hepatitis is one of five infectional factors cause early death in all over the world. every day at least one million people die because of viral hepatitis. six hepatitis viruses have been known until now. they are a, b, c, d, e, g, and it is probable that at least two other kinds i.e. f, and h, will be known soon. only hepatitis b is a dna virus, and the others are rna viruses. all viruse...
Abstract Background: Hepatitis B virus infection is an important cause of liver morbidity and mortality worldwide. HDV changes the natural course of HBV. The prevalence of HDV infection wasn’t determined in the various groups of HBV infection (carriers, acute hepatitis, chronic hepatitis, cirrhosis and HCC) in Iran. We aimed to research the prevalence of hepatitis D virus infection in v...
Background and purpose: Viral hepatitis is a systemic infection that mainly affects the liver. We studied the prevalence of skin lesions and infectious diseases including hepatitis A and B virus infection in patients attending Qaemshahr Razi Teaching Hospital, Iran 2013-2015. Materials and methods: In this retrospective descriptive study, records of patients diagnosed with hepatitis were inv...
800x600 background : hepatitis b and c infections have remained major global health burdens during the most recent century. the viral agents responsible for these diseases share common modes of transmission with human immunodeficiency virus (hiv) such as needle-sharing in iv drug abusers. coinfection of hepatitis b or c with hiv increases the rate of progression of chronic liver disease. given ...
Introduction: Prison, as the most important place for the transmission of infectious diseases, has particular importance, and prison populations are at high risk for infectious diseases like Hepatitis B & C. This study aimed to determine the prevalence of Hepatitis B & C among male inmates in six prisons of different provinces in Iran in 2012. Methods: In...
conclusions although the frequency of hbsag seropositivity in the present study was close to that observed in the overall iranian population, the seroprevalence of anti-hbc was higher, possibly due to the exposure of the elderly to more risk factors. the risk factors were similar. these included a history of blood transfusions, cupping, hospital admission, endoscopy, or familial hbv/hcv infecti...
background it is important to differentiate whether isolated anti-hbc is due to false positive results or the prior exposure to hepatitis b virus, because individuals with false-positive anti-hbc can benefit from vaccination and their blood can be safely transfused. to distinguish between these two conditions, we evaluated the serologic response to hepatitis b vaccine. methods ninety subjects w...
