Treatment using interferon injections may be considered as well. (apollohospitals.com)
The development of oral anti-viral treatment with nucleos(t)ide analogues (NAs) has revolutionised the management of chronic hepatitis B (CHB) in the last two decades. (medscape.com)
Treatment with pegylated interferon (Pegasys) -- either alone or in combination with the antiviral drug adefovir (Hepsera) -- led to clearance of hepatitis delta virus (HDV) and improvement in liver enzyme levels, according to a small study published in the January 27, 2011, New England Journal of Medicine . (hivandhepatitis.com)
Treatment for hepatitis delta has not been extensively studied and there are currently no approved therapies. (hivandhepatitis.com)
In the present analysis, Heiner Wedemeyer and fellow investigators with the Hep-Net-International Delta Hepatitis Intervention Trial (HIDIT) Study Group investigated the safety and efficacy of 48 weeks of treatment with pegylated interferon, adefovir, or the 2 drugs combined. (hivandhepatitis.com)
Although there are effective vaccines and treatment strategies against hepatitis B (HB), it is still a significant health concern worldwide that can present in acute, permanent, severe liver failure and cancer forms resulting in high morbidity and death. (sciendo.com)
Interferon therapy is not easy to take and there are numerous side effects including malaise, chills, fever, headache, myalgia, anorexia, and fatigue in most patients during the first few weeks of treatment. (hepatitiscentral.com)
Genotypes 1 and 4 are less responsive to interferon-based treatment than are the other genotypes (2, 3, 5 and 6). (creativebiomart.net)
There are 6 major genotypes of hepatitis C virus (HCV), which vary in their response to treatment. (msdmanuals.com)

Rather than attempting to determine the exact antigen on the cancer cells themselves, an alternative approach has been to isolate and to study the immunogobulins that our bodies have produced in recognition of these foreign antigens. (oncolink.org)

These cells, such as dendritic cells, process foreign antigens and then present them to T-cells, causing their intense activation. (oncolink.org)
In fact, immature dendritic cells can actually cause the suppression of responses to antigen. (oncolink.org)

Also excluded are patients who have concomittant liver disease with Hepatitis C or delta hepatitis. (hepatitiscentral.com)
This document provides the rationale for a comprehensive strategy to eliminate transmission of HBV and ultimately reduce the incidence of hepatitis B and hepatitis B-associated chronic liver disease in the United States. (cdc.gov)

Coronavirus illness (COVID-19) induces an alteration of Interferon (IFN) genes expression probably accountable for the noticed low HLA-DR expression in circulating monocytes (mHLA-DR). (jointsjournal.eu)

Moreover, for delta hepatitis, we are finally on the road to being able to achieve the same goals as hepatitis B through the development of drugs that block viral replication with the hope that they can also be effective for a definitive recovery. (mdpi.com)
Perrillo in 1990 showed that approximately 40% of patients treated with 5 million units of interferon daily for four months, responded by decreasing viral replication characterised by a loss of Hepatitis B DNA and e antigen. (hepatitiscentral.com)
CCR5 receptor antagonism inhibits hepatitis C virus (HCV) replication in vitro. (uc.edu)

Hepatitis D or delta virus is a defective pathogen that can only replicate in the presence of hepatitis B virus (HBV). (hivandhepatitis.com)

The latter example includes hepatitis B and C (for hepatoma or liver cancer), human papilloma virus (cervical cancer), and others. (oncolink.org)

Proliferative responses are often not associated with interferon-gamma release. (ox.ac.uk)
METHODS: T cell responses were evaluated longitudinally in 80 HIV/HCV coinfected individuals by ex vivo interferon-gamma-ELISpot responses to HCV core peptides, that predominantly stimulate CD4(+) T cells. (ox.ac.uk)

With the widespread use of anti-HBV agents in the past decades, particularly interferon-based regimens and nucleos(t)ide analogs, much progress has been made on the therapy of CHB. (hindawi.com)

In certain lymphomas, the immunoglobulin antigen that the lymphoid cell is supposed to be producing becomes mutated, and hence a potential target for vaccines. (oncolink.org)

Also at this time, the tests came back negative for the E-antigen, but I was still also negative for any antibodies. (hepb.org)

PEG-IFNα: Pegylated interferon alfa. (wjgnet.com)
Patients were allocated (1:1:1) to receive either 180 mcg/week pegylated interferon alfa-2a (Pegasys) plus 10 mg/day adefovir, the same dose of pegylated interferon plus placebo, or the same dose of adefovir alone for 48 weeks. (hivandhepatitis.com)

Results: Out of 1860 patients seen in hepatogastroenterology consultation 422 had viral hepatitis B or C that is a prevalence of 22.7% and 41 patients were treated (9.7%) by Pegylated Interferon. (scirp.org)
Egypt has the highest hepatitis C virus prevalence worldwide where about 24% of the people are estimated to carry HCV and more than 50% of blood donors have anti-HCV in some towns. (springeropen.com)
Egypt has the highest hepatitis C virus (HCV) prevalence worldwide where about 24% of the people are estimated to carry HCV [ 1 ]. (springeropen.com)

The aim of this study was to evaluate the impact of biofield modality on hepatitis B virus (HBV) and hepatitis C virus (HCV) in terms of viral load as surrogate marker. (longdom.org)

Patients with acute hepatitis should be monitored with blood tests in order to document biochemical improvement (see Workup). (medscape.com)
A small section of patients with acute hepatitis may develop acute liver failure which can be fatal. (apollohospitals.com)
Hepatitis C, Acute Hepatitis C is caused by an RNA virus that is often parenterally transmitted. (msdmanuals.com)
