Hepatitis B viral mutants can emerge in patients as a result of selection pressure from either immune response or treatment options. Mutations that occur within the immunodominant epitopes of hepatitis B surface antigen (HBsAg) allow mutant virus to propagate in the presence of a neutralizing immune response, while wild-type virus is reduced to undetectable levels. HBsAg mutants present as fals...
The essential role of multispecific immune responses for the control of hepatitis B virus (HBV) infection implies the need of multimodal therapeutic strategies for chronic HBV infection, including antiviral chemotherapy and immunomodulation. This hypothesis was tested in the woodchuck model by a combination of lamivudine pretreatment and subsequent immunizations of woodchucks chronically infect...
OBJECTIVE To evaluate current performance on recommended perinatal hepatitis B and rubella prevention practices in New Hampshire. METHODS Data were extracted from 2021 paired mother-infant records for the year 2000 birth cohort in New Hampshire's 25 delivery hospitals. Assessment was done on the following: prenatal screening for hepatitis B and rubella, administration of the hepatitis B vacci...
PURPOSE The spontaneous seroconversion rate of hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) virus infection in children is lower than that in adults. However, few studies have investigated the rate of transition from the immune-tolerant to the early immune-clearance phase in children. METHODS From February 2000 to August 2011, we enrolled 133 children aged <18 years who ha...
A collection of 104-fecal specimens from 45 patients with hepatitis A, 14 patients with hepatitis B, 10 patients with non-A, non-B hepatitis, 6 patients with diseases other than hepatitis, and 18 healthy adults were studied for the presence of secretory immunoglobulin A and immunoglobulin M to hepatitis A virus by solid-phase enzyme-linked immunosorbent assay and immune electron microsopy. Spec...
Numerous international institutions recommend vaccination against hepatitis B for all non-immune patients that consult for a sexually transmitted disease. It is a simple and safe procedure, frequently forgotten in dermatological clinics. Hepatitis B vaccine is administered via intramuscular route in the deltoid in 3 doses (at months 0, 1 and 6). The vaccine against hepatitis A is indicated for ...
A literature search was conducted using Google Scholar, Pak Medi Net and Pubmed databases. Two thousand three hundred twenty articles were found. After exclusion of irrelevant articles, only 18 satisfied the inclusion criteria. There nine studies from Punjab, KPK six Sindh. Total number patients 15,786. Mean age 57.7 years. Male constituted 50.9% females 49.05%. Immune chromatography performed ...
The immune response to intradermal or intramuscular hepatitis B vaccine in 18 children with insulin dependent diabetes mellitus (IDDM) compared with 24 healthy children was studied. Patients were divided into responders, hyporesponders, and non-responders according to their antihepatitis B serum concentrations after hepatitis B vaccination. We also studied HLA class II antigen distribution and ...
Hepatitis E virus (HEV) is a small RNA virus and the infectious agent of hepatitis E that occurs worldwide either as epidemics in Asia caused by genotype 1 and 2 or as sporadic disease in industrialized countries induced by genotype 3 and 4. The frequency might be underestimated in central Europe as a cause of acute hepatitis. Therefore, we analyzed on liver biopsies, if cases of acute hepatiti...
