results it was found that the positive hepatitis b surface antigen (hbsag), the high baseline hbv dna level, the positive hepatitis b virus e antigen (hbeag), and an absent or low hepatitis b surface antibody (hbsab) titer prior to starting treatment are the most important viral risk factors. furthermore, rituximab, anthracycline, and different types of tnf-α inhibitors were identified as the h...

results the mean age of children was 6.5 ± 4.2 years. the frequency of positive results for hbsag, anti-hbs and anti-hcv in all age groups were 12 (3.6%), 47 (14.2%) and 2 (0.6%), respectively. anti-hiv was not detected in any of the children's serum samples. the frequency of positive results for hbsag was significantly higher in children older than six years than in other age groups. conclusio...

context hepatitis b vaccination of hemodialysis patients is performed all over the world. there are also recommendations from world health organizations to vaccinate patients with chronic kidney disease (ckd) prior dialysis commencement, but the implementation of a hepatitis b vaccination program is less common and not well organized. evidence acquisition this review article summarizes data ind...

background and aims: lamivudine is amongst the antiviral for drug chronic hepatitis b treatment. during therapy with lamivudine, variants may emerge with ymdd mutation in the reverse transcriptase (rt) region of polymerase gene. this mutation might have a role in drug resistant for hbv. materials and methods: hbv dna extraction from serum sample of 88 patients, were subjected to nested pcr for ...

background: generally, a number of people with î²-thalassemia are susceptible to hbv since they receive multiple blood transfusions. these people have high infection rates despite vaccination against hbv. in this study, we explore the seroprevalence and risk factors of hbv infection in thalassemic patients who reside in ardabil. materials and methods: hospital in ardabil. patients' demographic ...

the aim of this study was to investigate the prevalence of hepatitis b virus (hbv) genotypes in isparta, southwest of turkey, as well as the clinical features and transmission route for patients with hbv infections. methods: patients (n = 135) with hbv infection were included in the study. epidemiological and clinical data were obtained. hbv genotypes were determined with a pres2 epitope elisa ...

background: blood transfusion plays a great role in public health and the blood safety still has remained a main concern. hbv has been considered as one of the most prevalent blood borne infections. it is estimated that chronic hbv affects 350-400 million people worldwide. comprehensive knowledge about hbv has high importance in iran due to high number of blood dependent patients. material and ...

the most frequently studied association between a hepatitis virus and non hodgkin lymphoma (nhl) has been with hepatitis c virus (hcv). association with hepatitis b virus (hbv) is less studied. in this regard mixed cryoglobulinemia (mc) is more commonly associated with hcv than hbv. still rarer is cryofibrinogenemia in these patients.   lack of symptoms in addition its rarity delays the diagnos...

introduction: occurrence of detectable amounts of viral antigen or viral particles in the blood of infected patients with hepatitis b virus (hbv) is a significant characteristic of hbv infection. detection of hbv antigen or its dna among individuals of a community is a crucial factor to know the burden of hbv infection. hepatitis b surface antigen (hbsag) is a suitable marker of hbv infection b...

conclusions in our study, only hbv genotype d was found among all the positive hbsag and occult hbv infection. moreover, high prevalence (40.7%) of occult hbv infection was determined among patients suffered from cryptogenic cirrhosis. results eleven (40.7%) out of 27 hbv cryptogenic cirrhosis and all 11 hbsag-positive patients were positive for hbv dna. the seroprevalences of hepatitis b virus...
