Background and Aim: Hepatitis E is a viral disease transmitted through contaminated water, which is most commonly reported as an epidemic. Mental retardation among high-risk groups are at high risk of infection, Therefore, the present study was designed and conducted to evaluate the seroepidemiology of hepatitis E in mentally retarded individuals. Materials and Methods: This cross-sectional de...
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...
DNA coding for the core antigen from hepatitis B Virus (HBcAg) was amplified, cloned and propagated in E. coli. The core protein was expressed in E. coli and the product was readily detected by Western blot. This protein can be used as a diagnostic material in serum screening tests. To increase the level of expression of this antigen in bacteria, two plasmids were constructed in which the gene ...
Background and Aims: Hepatitis E virus (HEV) is considered as one of the common causes of acute viral hepatitis in the world, particularly in the developing countries. It also causes fulminant hepatitis in pregnant women. Although HEV infection in Iran is endemic, there are numerous reports of epidemics caused by this infection in this part of the world. This study aimed to determine seropreval...
type e hepatitis is caused by an unclassified virus producing acute self-limited hepatitis in different parts of the world. in order to estimate the prevalence of hepatitis e virus seropositivity in tehran blood donors, a cross– sectional study was performed by the enzyme immunoassay method from 2003 to 2004 in a group of 90 blood donors. we noticed that 7 cases (7.8%) were anti-hev ab positive...
background: hepatitis e virus is an enterically transmitted virus that is endemic in south asia and this virus is one of the most important cause of acute hepatitis in this region. although hepatitis e virus (hev) is not a leading cause for chronic hepatitis, the role of hev in exacerbation of chronic liver disease is certain. materials and methods: 100 cirrhotic cases (50 hepatitis b and 50 he...
conclusions vaccination of non-immune individuals against hav infection in high risk groups especially hemophilia and thalassemia patients is recommended. results did not show any differences about seroprevalence of hev among iranian general population. results anti-hav igg antibodies were observed more frequently in thalassemia patients (60/64; 93.8%) than in hemophilia patients (104/155; 67.1...
conclusions one in five patients undergoing maintenance dialysis in hamadan is seropositive for hepatitis e immunoglobulin g antibody. future studies are needed to investigate the factors contributing to the observed high prevalence rate and the possibility of parenteral transmission of hepatitis e. results thirty patients (19.2%), were seropositive. seropositive patients were not significantly...
BACKGROUND Hepatitis E virus infection usually causes an acute and self-resolving hepatitis. In areas where chronic hepatitis B virus infection is prevalent, acute hepatitis E virus superinfection on chronic hepatitis B virus infection occurs sporadically. In recent years, however, chronic hepatitis E virus infection has been recognized in patients under immunosuppressant therapy. To the best o...
BACKGROUND Hepatitis E is an acute viral disease of humans, occurring in explosive outbreaks in the developing world and as sporadic cases in returning travellers. Increasing recognition of indigenous transmission in Western countries suggests a zoonotic source of infection, most likely pigs. To determine if hepatitis E virus is present in Irish pigs, sera from 330 animals were examined for ant...
