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...

methods and materials: hepatitis b virus dna was detected by conventional pcr in some of the serum samples obtained from hbsag-positive chronic hepatitis b (chb) patients who were referred to health centers of shahrekord for routine monitoring of the disease. subsequently, using real-time pcr, the dna samples were used for genotyping and analysis of resistance to lamivudine. results: the dna wa...

conclusions in conclusion, occult hbv was found in 36% of patients with negative results for hbsag, but positive results for hcv. detection of hbv-dna in both pbmcs and plasma together in comparison with plasma alone provided more true identification of obi.the svr rate was significantly higher in coinfected patients than mono-infected ones. background occult hepatitis b virus (hbv) infection (...

background and aims: many studies have provided evidence for the role of hepatitis b and c viruses in the development of liver cancer. although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with hbv and hcv. this study was performed to determine the frequency of hbv/hcv-coinfection in mashhad, north-east of iran. mat...

background : hepatitis b virus (hbv) and hepatitis c virus (hcv) infections are major global public health problems. this study was conducted to investigate the incidence rate of these infections over six successive years in hamadan province, the west of iran. methods: this retrospective cohort study was conducted on the database of hepatitis registry. in this study, 1257 subjects infected by h...

background : hepatitis b virus (hbv) is one of the most popular causes of chronic liver diseases through the world. there are approximately 350 million individuals infected with the hbv that 15 to 20 million of them are co-infected with hdv. it is known that co-existent infection with hdv tends to accelerate the progress of chronic hbv infection to chronic hepatitis, cirrhosis and hepatocellula...

background: the clinical significance of antiphospholipid antibodies in patients with chronic hepatitis c virus (hcv) and some other viral infections is controversial. objective: to study the prevalence of anticardiolipin antibody (acla) and antibeta2glycoproteini antibody (antibeta2gpi antibody) in hcv and hepatitis b virus (hbv) infected patients and its association with liver clinical parame...

context several risk factors play the role in the development of hepatocellular carcinoma (hcc) from which chronic hepatitis b and c infections are the most important ones. dna integration of hepatitis viruses alters the function of critical genes promoting malignant transformation of virus-infected liver cells. evidence acquisition there are remarkable geographic differences in prevalence of c...
