BACKGROUND Enterically-transmitted acute viral hepatitis is caused predominantly by hepatitis A virus (HAV) and hepatitis E virus (HEV). The prevalence of HEV and HAV infections varies in different geographical regions. OBJECTIVES This study was conducted to determine the prevalence of HEV and HAV infections among Iranian healthy individuals in southern Iran. PATIENTS AND METHODS Totally, 1...

Hepatitis A vaccines prepared by formalin inactivation of purified cell-culture grown hepatitis A virus are licensed in several European countries. The potencies of these vaccines are expressed in units unique to each manufacturer. Standardisation of potency statements requires establishment of an international reference material. At its 1999 meeting, the ECBS(2) established a preparation coded...

Background: The prevalence of hepatitis B and C in Iranian children with chronic kidney disease is limited. Therefore, the present study intends to assess the prevalence of hepatitis B and C in children with chronic kidney disease (CKD).Method: The present study is a historical cohort study which was conducted in a window period of 25 years in Children’s Medical Center in Tehran, 1991-2016. Dat...

Hepatitis A virus (HAV) is transmitted via the fecal-oral route from contaminated food or water. As part of the most recent survey of viral hepatitis burden in Thailand, we analyzed the current seroprevalence of HAV in the country and compared with data dating back to 1971. From March to October, 2014, a total of 4,260 individuals between one month and 71 years of age from different geographica...

BACKGROUND/AIMS The aim of the study was to determine the epidemiological shift that may have occurred in the last 11 years of Hepatitis A virus (HAV) seroprevalence. MATERIALS AND METHODS In 1998, we reported the anti-HAV seroprevalence in 711 children aged between 2 and 16 years children in Adana city center. Eleven years later we repeated the same study at the same locations in a similar p...

BACKGROUND/AIMS The nonspecific clinical presentation of acute hepatitis A (AHA) mandates the detection of anti-hepatitis A virus IgM antibodies (IgM anti-HAV) in the serum for obtaining a definitive diagnosis. However, IgM anti-HAV might not be present during the early phase of the disease. The aim of this study was to determine the optimal time for repeating the IgM anti-HAV test (HAV test) i...

Background: SEN virus (SENV) is the latest virus proposed as a cause of unknown hepatitis cases. Among nine detected genotypes of the virus, genotypes D and H are more frequent in hepatitis cases of unknown origin. The aim of this study was to determine the frequency of SENV-D and SENV-H genotypes in the sera of healthy individuals and hepatitis B and C patients. Methods: Totally, 200 serum sam...

psychosis, a relatively common condition that affects 3%-5% percent of the population, occurs in a variety of diagnostic contexts. various medical conditions may lead to the development of psychotic symptoms. to date psychotic disorders due to infection with hepatitis a virus (hav) have â been â rarely reported. in this paper, we described an acute psychotic disorder in an 18-year-old male diag...

conclusions it appears that anti-hav antibody seroprevalence has declined among children below 15 years with and without chronic liver disease, and it is likely that more children would be susceptible to hav infection. therefore, it is important to employ preventative strategies against hav in chronic liver diseases. results seroprevalence of hav was 17.8% and 10% in the first and second study,...
