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...

conclusions the results of this study revealed the important role injection drug use plays as the main cause of hcv spread in isfahan province. effective harm reduction programs should be implemented to prevent new hcv infections. considering the high prevalence of hcv infection among hiv patients, this group should receive special attention. results twenty-eight studies, including 6, 17, 4, an...

results the study found that 72 patients, 43 males and 29 females, had documented hcv infections. age’s ranged from 20 - 75, with a mean of 48. the largest number of patients had the 1a genotypes (41 patients = 56.9%), followed by 3a (25 patients = 34.7%), and 1b and 4a each of them (3 patients = 4.2%). conclusions the study showed that genotypes 1a and 3a are the most common genotypes in patie...

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 in each region is of great importanc...

results in patients with an svr, the serum levels of aminotransferases were decreased after hcv eradication. although general liver functional tests (albumin and total bilirubin) did not significantly change, the btr values significantly increased. however, in patients without an svr, an improvement in the btr value was not observed after ifn treatment. conclusions hcv eradication can improve t...

conclusions it is suggested that determination of the target genotype by plasma subtyping for choosing the proper antiviral therapy is essential but may result in therapy failure. hcv genotyping in pbmc samples, along with plasma specimens, might be more beneficial. therefore determining the hcv genotype in pbmcs, before beginning the therapy is useful due to the possibility of occult infection...

background: hepatitis c (hcv) is increasing worldwide including iran. hcv is more prevalent among intravenous drug abusers (idu), especially if imprisoned, mostly due to needle sharing. we determined the rate of hcv seropositivity among idu prisoners and compared it with those of non prisoners. materials and methods: a cross-sectional survey was done on consenting idu inhabiting two prisons and...

Hepatitis B is a liver inflammation caused by hepatitis B virus (HBV) and can be diagnosed in clinical stage by hepatitis B core antibody from IgM class (anti-HBcIgM). Hepatitis B core antibody from IgG class (Anti-HBcIgG) appears quickly after IgM, reaching high titers in chronic hepatitis, and remains even after cure. Since hepatitis B core antibody (anti-HBc) is the first antibody identified...

background previous studies using cell culture systems for the replication of hepatitis c virus have opened new research dimensions, and paved the ways for further and detailed studies of the virus in vitro. objectives the purpose of the present study was to cultivate hepatitis c virus in a cell culture system and evaluate viral amplification. materials and methods in order to propagate hepatit...

introduction: intravenous drug users as a serious health problem in communities have economical and social effects as well as health and hygienic complications. viral infections may be transmitted through drug injection by shared syringes among users. the aim of this study has been to determine the relative frequency of hbv, hcv and hiv infection’s markers as epidemiological data in ahvaz. mate...
