background: there is a controversy about the relation between anti-hepatitis b (anti-hbs) antibody level and obesity. we designed this study to compare the vaccine efficacy in obese/overweight and non-obese cases. methods: in this cross-sectional study, 242 obese/overweight and 85 non-obese individuals were participated. cases were selected from a referral clinic for obesity and a referral hepa...

Methods: Treatment naive CHC patients were enrolled. They were classified into 2 groups according to presence or absence of PHT. Patients were subjected to liver function tests (LFTs), hepatitis C virus antibody (HCV-Ab), hepatitis B surface antigen (HBs-Ag), anti-nuclear antibody (ANA), Bilharzial agglutination titer, ultrasound abdomen and oesophago-gastro-duodensocpy. Egy-Score, ASTto-Platel...

OBJECTIVE To investigate the influence of chemotherapy (CT) on HBsAb titer in patients receiving CT due to hematological malignancy. MATERIALS AND METHODS The data of 75 patients who received CT with the diagnosis of various hematological malignancies and who had serum HBsAb levels measured prior to and after the cessation of CT were evaluated retrospectively. RESULTS The median age of the ...

     Thimerosal, which is approximately 50% mercury by weight is a preservative widely used in vaccines since the 1930’s. It meets the requirements for a preservative as set forth by Pharmacopeia challenge test and has been shown to be effective against a broad spectrum of pathogens. In July 1999, the Public Health Service agencies and vaccine manufacturers agreed that thimerosal should be redu...

A study was made of latent hepatic diseases in university students. 1.4% to 1.6% of the students were positive for hepatitis B surface antigen (HBsAg), and 10.3% for anti-HBs. Of 28 students with HBs-antigenemia, 2 had chronic persistent hepatitis, and 3 minimal hepatitis, 23 being healthy carriers. Hepatitis B e-antigen (HBeAg) was detected in 44% of the students with HBsAg, and anti-HBe in 13...

BACKGROUND Hepatitis B vaccination is recommended for health care workers but has a nonresponse rate of 5% to 32% and an unknown duration of immunity. There is no standardized postvaccination protocol to confirm, monitor, and maintain immunity. OBJECTIVE To assess the hepatitis B serologic immune status in health care workers who were previously vaccinated. METHODS A convenience survey and ...

Diagnosis of hepatitis B virus (HBV) infection based on hepatitis B surface antigen (HBsAg) detection can be hampered in the setting of HBV reactivation in immunocompromized patients with prior serology indicating past cured infection, and can be associated with severe or fulminant and fatal hepatitis. We present a case of HBV reactivation in a renal transplant patient in whom HBsAg failed to b...

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...

BACKGROUND A gap exists in the literature on celiac disease populations and the response to hepatitis B vaccination. OBJECTIVE To identify pediatric patients with celiac disease who received the primary hepatitis B vaccination and investigate their response to vaccine. DESIGN/METHODS Patients underwent blood draw for hepatitis B surface antibody titers. Patients with undetectable or non-pro...

This community-based prospective study examined the effects of viral infections and lifestyle habits on hepatocellular carcinoma (HCC) risk in Japan. A baseline survey was conducted for 981 males and 2,078 females in June 1992 and evaluated hepatitis B surface antigen, second-generation hepatitis C virus antibody, and history of cigarette smoking and habitual alcohol consumption. By March 1997,...
