The correlation of HBeAg, anti-HBe, Dane particles and results of light microscopy of liver biopsies have been studied in 109 patients with chronic HBV infection and in 21 HBsAg carriers. The following conclusions may be drawn: 1. There is a good correlation between the presence of HBeAg and Dane particles. 2. Patients with both of these markers often have chronic active or lobular hepatitis. 3. The presence of anti-HBe points in 80% of these cases to a carriership or chronic persistent hepatitis. 4. 60% of patients without an HBe-marker and 20...

The authors have looked for the markers of HBV by R.I.A. method (HBsAg, anti HBsAg, HBeAg, anti HBeAg, anti HBcAg), of HAV (by measurement on two samples of HAVab or by measurement of HAVab IgM), the immune-complexes (I.C.C.) by C1q solid-phase binding assay method with E.L.I.S.A. with determination after division I.C.C. of HBsAg by R.I.A. method in 33 cases of HBsAg negative acute viral hepatitis. The 9% (3 cases) were HAV acute hepatitis, the 42,4% (14 cases) no A no B acute hepatitis, the 36,3% (12 case) were HBV acute hepatitis, in 9 anti H...

Two batches of a new hepatitis A/hepatitis B combined vaccine were tested in 242 healthy students. Three injections, given at 0, 1 and 6 months, produced seroconversion rates and hepatitis A virus (HAV) and hepatitis B surface antigen (HBsAg) antibody levels comparable to those reported after administration of separate monocomponent vaccines. The vaccine proved to be safe and well-tolerated. Influence of host factors, such as elevated body mass index or gender, were investigated and proven to be of little influence on the immunoresponse.

Fourteen children with biopsy-proven membranous nephropathy associated with hepatitis B virus (HBV-MN) were evaluated biochemically and serologically and compared to 45 children with idiopathic nephrotic syndrome (INS). The mean ages of the two groups were similar (4.9 +/- 1.6 vs. 4.6 +/- 2.6 years). Serum albumin levels were similar in both groups, but serum cholesterol was significantly reduced in children with HBV-MN compared to INS. Serum C3 was also significantly depressed in children with HBV-MN compared to INS, but no differences in C4 l...

Aim: The aim of this study was to compare the clinical applicability of quantitative serum hepatitis B surface antigen (HBsAg), hepatitis B e-antigen (HBeAg) and hepatitis B virus (HBV) DNA for predicting virological response (VR) to pegylated interferon (PEG-IFN) therapy. Methods: Thirty HBeAg-positive chronic hepatitis B patients who received PEG-IFN-alpha-2b for 48 weeks were enrolled. Quantitative HBsAg, HBeAg and HBV DNA were measured before, during and after the therapy. Paired liver biopsies were performed before and after treatment for ...

The objective of this study was to evaluate the role of hepatitis B virus (HBV) precore mutations in patients with anti-HBe-positive chronic hepatitis B with or without previous known HBe antigen (HBeAg) viremic phase, and to assess the potential implication of precore mutants in HBeAg-negative reactivation after loss of HBeAg. Nineteen patients were studied: 7 had a previous HBeAg-positive phase and had spontaneous or therapeutically induced loss of HBeAg (group A); 12 had no previous HBeAg-positive phase (group B). Direct sequencing of PCR pr...

Sporadic non-A, non-B hepatitis is the most common indication for liver transplantation in patients presenting with fulminant and subacute liver failure. This study used serological, histological, and molecular biological techniques to examine specimens from 23 consecutive patients transplanted for sporadic non-A, non-B hepatitis. No evidence was found of hepatitis C virus, hepatitis E virus, or 'cryptic' hepatitis B virus infection.

The etiology of sporadic acute hepatitis was studied in 334 consecutive patients from Taiwan (237 men and 97 women, aged 16-81 years), with emphasis on the role of hepatitis C virus (HCV), hepatitis E virus (HEV), and GB virus-C/hepatitis G virus (GBV-C/HGV) in acute non-A, non-B (NANB) hepatitis and in HBsAg carriers with superimposed acute hepatitis. According to the conventional diagnostic criteria, there were 12 cases (3.6%) of acute hepatitis A, 17 cases (5.1%) of acute hepatitis B, 128 cases (38.3%) of acute NANB hepatitis, and 177 cases ...

BACKGROUND: Several studies have shown that hepatitis B immunoglobulin (HBIG) imposes a selection pressure on the hepatitis B virus (HBV) S gene, and that the emergence of mutations in this region would make reinfection after orthotopic liver transplantation (OLT) possible. AIMS: This study was undertaken to analyze the presence of HBV S-gene mutations in the different stages of HBV infection and the relationship between HBIG therapy and the emergence of mutations in liver transplant recipients. METHODS: The frequency and location of mutations ...

To assess the significance of cell-mediated immunity, T cells were derived from the peripheral blood and liver tissue of hepatitis B virus (HBV)-infected patients and controls. The analysis of the 3H-thymidine-uptake in response to a panel of recombinant HBV antigens revealed that peripheral blood mononuclear cells (PBMC) of the 25 viremic patients with inflammatory active, chronic hepatitis B, 16 with wild-type and nine with HBe-minus HBV mutant infection, showed stronger proliferative responses to HBc and HBe antigens than 16 asymptomatic non...

Sera from 102 black patients with primary hepatocellular carcinoma (PHC) and hepatitis B surface antigenemia were tested for immunoglobulin M antibody against hepatitis B core (IgM anti-HBc), hepatitis B e antigen (HBeAg), and hepatitis B viral (HBV) DNA. Their prevalences were compared to those of a control group of 124 age and sex matched black HBV carriers without tumor. IgM anti-HBc was present in 68.6%, HBeAg in 32.3%, and HBV-DNA in 26.7% of the patients. In the control population, IgM anti-HBc was present in 45%, HBeAg was detected in 3....

A 22-year-old male Taiwanese was admitted to the hospital for acute hepatitis B associated with fulminant hepatic failure. After receiving supportive treatment, the patient's clinical condition improved and the results of liver function tests (including prothrombin time) gradually improved. However, in spite of seroconversion from hepatitis B surface antigen to antibody, hepatitis relapsed and serum alanine aminotransferase levels were persistently abnormal during the 3-year follow-up period. Liver biopsy performed 2 years after the onset of il...

BACKGROUND: The association and profile of surface gene mutations with viral genotypes have been studied in patients with chronic hepatitis B virus (HBV) but not in subjects with occult HBV infection. AIM: This study aimed to investigate the association of surface gene mutations with viral genotypes in occult HBV infection. MATERIALS & METHODS: Of 293 family contacts of 90 chronic HBV index patients, 110 consented for the study. Of 110 subjects, 97 were hepatitis B surface antigen (HBsAg) negative. HBV genotyping was done using direct DNA seque...

We describe here a severe flare of hepatitis caused by lamivudine-resistant hepatitis B virus(HBV) in an HIV/HBV co-infected individual.Lamivudine-resistant HBV was detected 6 months before the development of severe hepatitis. Sequencing of the HBV genome isolated from the patients' serum did not identify compensatory mutations in the HBV polymerase that may have restored viral replication. However, a strong HBV-specific CD8 T-cell response was identified and may have resulted in the severe hepatitis.

The hepatitis D virus (HDV) infection plays a major role in severe liver damage caused by hepatitis. To establish the prevalence of HDV infection in haemophilic patients and patients without haemophilia, 87 patients with chronic hepatitis B virus (HBV) infection were examined for serological evidence of delta hepatitis. In addition HBV, HDV and human immunodeficiency virus type 1 (HIV) infection markers were compared to clinical and histopathological outcome of hepatitis. Out of 46 haemophiliacs 30 (65%) were anti-HD-seropositive; 10 out of 30 ...
