Hepatitis B virus (HBV) surface antigen (HBsAg) was found in 9.2% of 1,186 pregnant women from Gabon, of whom 10.1% had the HBe antigen and 89.9% had anti-HBe antibodies. Antibodies to the hepatitis delta virus (HDV) were found in 15.6% of the HBsAg-positive women. The HBV strains were of the A3 and E genotypes. The HDV strains belonged to HDV clades 1 and 8. These results provide clear evidenc...

The simultaneous development of acute hyperparathyroidism and viral hepatitis B infection in a 72 year old male is described. Resolution of the hepatitis was accompanied by improvement in the parathyroid hormone mediated hypercalcaemia. It is postulated that antibodies to the hepatitis B virus may have altered the calcium 'set point' allowing uncontrolled synthesis and release of parathyroid ho...

measles, rubella, mumps, hepatitis b virus (hbv) and varicella zoster virus (vzv) cause infectious diseases that can be effectively prevented by vaccination. vaccination of medical students is important, because they are more likely to become exposed and infected by these viruses. a total of 180 students, consisting of 90 women and 90 men, were serologically screened for measles, rubella and mu...

Result: Thirty-one patients (48.4%) were diagnosed with hemophilia A,eighteen patients (28.1%) had von Willebrand disease, eleven patients (17.9%) had Hemophilia B and four patients had other factor deficiencies. Elevenpatients with Hemophilia A and one patient with Hemophilia B had severe disease. The prevalence of hepatitis C virus infection was 5%. All patients were negative for hepatitis B ...

context hepatitis b and hepatitis c (hbv and hcv) infections are both major causes of hepatocellular carcinoma (hcc). however, hcc caused by each of these two viruses has unique characteristics that should be studied independently to that of another one. while hbv- and hcv-related hccs share similar host and environmental risk factors such as male gender, age above 50 years old, family history ...

background: because dental staff members are in continuous contact with blood and contaminated fluids of patients, they are considered as a high risk group. their knowledge about standard precautions is thus important in preventing infectious diseases such as hepatitis and human immunodeficiency virus (hiv). the purpose of this study was to estimate the injuries that occur in dental staff and t...

background and aims: recently, a novel dna virus was isolated from the serum of a patient with post-transfusion non a-g hepatitis and named tt virus. the aim of this study was to determine the prevalence tt virus among cirrhotic patients due to hepatitis b & c in infection ahwaz. methods: the prevalence of ttv infection was studied in 41 patients with liver cirrhosis. ttv dna was detected by se...

OBJECTIVES To evaluate the prevalence of occult hepatitis B viral infections (OBIs)  among blood donors considering the clinical and epidemiological importance of identifying OBIs. METHODS A cross-sectional study conducted at King Khalid University Hospital, Riyadh, Saudi Arabia between January 2011 and January 2012. Blood donors (n=8501) were screened for Hepatitis B virus surface antigen (H...

BACKGROUND We have constructed and clinically evaluated a hypoallergenic vaccine for grass pollen allergy, BM32, which is based on fusion proteins consisting of peptides from the IgE binding sites of the major grass pollen allergens fused to preS (preS1+preS2), a domain of the hepatitis B virus (HBV) large envelope protein which mediates the viral attachment and entry. Aim of this study was the...
