Helicobacter pylori and hepatitis A virus (HAV) are thought to have similar routes of transmission and epidemiology. This study investigated the seroprevalence of these 2 pathogens among children in rural, central Taiwan. Serum samples were collected from 856 children between 2010 and 2012 and levels of anti-HAV and anti-H. pylori antibodies were measured by ELISA. Questionnaires were used to i...

  Background and Objective: The outcome of hepatitis B virus (HBV) infection may be influenced by host factors like Human Leukocyte Antigen (HLA). We have investigated HLA-A and DRB1 alleles in patients with persistent hepatitis B infection compared to subjects who had spontaneously recovered from HBV infection. To complete the findings of this study we performed another survey in certain HLA ...

Background and aims: Hepatitis B virus (HBV) is one of the important public health diseases in Iran.Therefore, to control the prevalence of the disease, knowledge is required regarding the risk factor ofHBV. Accordingly, the aim of this study was to determine the risk factors of HB transmission.Methods: A retrospective case-control study was conducted on the possible risk fact...

Hepatitis A virus (HAV) infection is common in Southeast Asia, and most of the inhabitants acquire a lifelong immunity as a result of natural infection during childhood. However, the age-specific seroprevalence is changing with development of socioeconomic and hygiene status in this area and the infection is predicted to shift to adulthood with more severe clinical manifestations in the future....

Background: Although regular frequent blood transfusion improves overall survival of multi-transfused patients like β-thalassemic ones, it carries a definite risk of infection with blood-borne viruses such as viral hepatitis. This study was done to determine seropositivity of hepatitis B virus (HBV), hepatitis C virus (HCV), and Human Immunedeficiency Virus (HIV) infections among β-th...

Background: Recently, some new viruses have been identified for their association with hepatitis which Torque Teno Mini Virus being among them. The aim of this study was to determine the frequency of Torque Teno Mini Virus in healthy individuals and hepatitis B and C patients in Isfahan, Iran. Materials and Methods: One hundred serum samples of healthy individuals from Isfahan Blood Transfusi...

results findings showed that the genotype -607a/a is associated with the susceptibility to chronic hepatitis b. furthermore, allele c at position -137 is suggested to play a protective role against development of chronic hbv infection. conclusions host genetic factors play an important role in determining the outcome of hbv infection. it is suggested that il-18 genotype -607 a/a is associated w...
