BACKGROUND AND OBJECTIVES Hepatitis E virus (HEV) is a major public health concern in developing countries. HEV transmission occurs primarily by the fecal-oral route. It has also been reported that blood donors are potentially able to cause transfusion-associated hepatitis E in endemic areas. This study aimed to determine the seroprevalence of HEV infection(More)
BACKGROUND T-helper (Th) lymphocyte cytokine production may be important in the immune pathogenesis of hepatitis C virus (HCV) infections. Th1 cytokines such as; interleukin-2 (IL-2), and interferon gamma (IFN-gamma) are necessary for host antiviral immune responses, while Th2 cytokines (IL-4, IL-10) can inhibit the development of these effector mechanisms.(More)
BACKGROUND Single nucleotide polymorphisms (SNP) in the promoter region of the interleukin (IL)-10 genes have a role in determining hepatitis B virus (HBV) outcome. OBJECTIVES This study evaluates the correlation between HBV infection and SNP in IL-10 gene promoter. PATIENTS AND METHODS Ninety-six HBV-infected patients (32 chronic hepatitis B infection(More)
CONTEXT The clinical outcome of hepatitis B virus (HBV) infection is variable, ranging from spontaneous recovery to an inactive carrier state, chronic hepatitis, occult HBV infection, liver cirrhosis, or hepatocellular carcinoma. EVIDENCE ACQUISITION This variable pattern and clinical outcomes of the infection were mainly determined by virological and(More)
BACKGROUND AND OBJECTIVES Brucellosis is a zoonotic disease and it's still endemic in Iran. There are some reports regarding brucellosis infection in family members sharing same risk factors and remain unrecognized. However, few studies on the importance of family screening are available. We aimed to screen household members of index cases with acute(More)
BACKGROUND AND OBJECTIVES Tetanus and diphtheria are vaccine-preventable, infectious diseases with significant morbidity and mortality. Immunization by the diphtheria and tetanus toxoid (DT) has been applied in Iran for almost 50 years. However, there are very few data about the rate of immunity to these diseases in the adult population. the humoral(More)
cult hepatitis B infection in different high risk patients. We read with great interest the article " epidemiology of occult hepatitis B infection among thalassemia, hemo-philia and hemodialysis patients " by Arababadi et al. (1). because of our common field of interest in investigation of occult hepatitis B infection (OBI) in high risk patients such as HIV(More)
BACKGROUND AND OBJECTIVES Hepatitis C virus (HCV) infection is a worldwide concern and it is the major cause of liver disease. Several genotypes of the HCV have been reported from different regions of the world. The determination of the HCV genotypes is important for the prediction of response to antiviral treatment and clinical outcomes. So, HCV genotyping(More)
Background. Dietary supplementation has been used as a mechanism to augment the immune system. Adjunctive therapy with L-arginine has the potential to improve outcomes in active tuberculosis. Methods. In a randomized clinical trial 63 participants with smear-positive pulmonary tuberculosis in Markazi Province of Iran were given arginine or placebo for 4(More)
BACKGROUND Occult Hepatitis B virus (HBV) infection (OBI) is defined as the presence of HBV-DNA in the liver or serum with undetectable hepatitis B surface antigen (HBsAg). Hemodialysis (HD) patients are at risk of acquiring parenterally transmitted infections. OBJECTIVES The aim of this study was to assess the prevalence of OBI in HD patients. PATIENTS(More)
