Active clinical trials for "Hepatitis"

The purpose of this study is to provide insights into the cause, development and effects of de novo autoimmune hepatitis so that prevention and treatment strategies can be developed in order to reduce post-liver transplant morbidity, the frequency of liver allograft loss and the need for re-transplantation.

The purpose of this study is to evaluate the safety and tolerability of multiple ascending doses of HM10660A in subjects with chronic hepatitis C(HCV).

Hepatitis B Virus Antibody Booster Program

The purpose of this study is to evaluate the efficacy and safety of generic entecavir monotherapy or in combination with adefovir for chronic hepatitis B patients with inadequate response to NUC therapy

This is a non-interventional study designed to evaluate the efficacy and safety of combination study drugs in the treatment of participants diagnosed with Chronic Hepatitis C (CHC). CHC participants with confirmed positive hepatitis-C virus (HCV) RNA in plasma, and who have not been previously treated with the Pegylated interferon (PegIntron) Pen, were enrolled into study.

For HIV-infected patients who have access to treatment, liver diseases are a major cause of morbidity and mortality. Hepatitis C is the most frequently encountered liver condition in this population. Both diseases allow a higher level of poisonous substances (toxins) normally produced by the bacteria present in the gut to enter the bloodstream. This leads to a chronic inflammatory state, which results in faster development of liver scars (fibrosis) and ultimately, end stage disease (cirrhosis). To prevent this from happening, the use of antibiotics has been attempted to reduce the quantity of gut flora in the hopes of lowering the amount of toxins produced. These trials have shown promising results, but the antibiotics studied had major side effects and were not designed for continuous use. Rifaximin is a non absorbable antibiotic with very few side effects. It is already used for long periods of time in cirrhotic patients to treat the effects of cirrhosis on the brain (encephalopathy). This project will try to determine if rifaximin, by reducing the level of toxins produced by the bacteria in the gut, can improve the evolution of liver fibrosis in HIV-infected patients with hepatitis C. In this pilot study, ten patients with HIV and HCV infection will be followed for one year. In addition, 10 patients with HCV mono infection will also be followed. Both populations will be included if they are starting on rifaximin, for its currently approved FDA indication (hepatic encephalopathy).

This observational study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) in patients with chronic hepatitis B who have failed antiviral treatment with nucleoside (nucleotide) analogues. Data will be collected from patients treated according to the current Summary of Product Characteristics and local standard of care and regulations during 48 weeks of treatment and 24 weeks of follow-up.

Abstract Telbivudine is a potent inhibitor of HBV but, due to a low genetic barrier to resistance, a high incidence of resistance has been observed in patients with high baseline levels of replication and in those with detectable HBV DNA after 24 weeks of therapy (A1). Telbivudine might be used in patients with good predictors of response (HBV DNA <2 X 106 IU/ ml, i.e. approximately 107 copies/ ml, or 6.3 log 10 IU/ ml at baseline) with verification of HBV DNA suppression below detection in real time PCR assay at 24 weeks.(EASL Guidelines for HBV 2009) The therapy of Pegylated-interferon-alpha-2a is considered as the standard of care for patients with chronic hepatitis b viral infection. However, recent study by Buster et al showed that a sustained viral response (SVR less than 2000 iu.ml at 6 months after treatment)) is obtained in 8 % of patients with genotype D, 30% genotype A, and 20-25% genotypes B or C (47). Vitamin D is a potent immune-modulator; and has been shown to improve SVR in combination with peg interferone in patients with chronic HCV viral infection (48). The impact of vitamin D on virologic response rates of interferon-based treatment of CHB is unknown. The aim of this study therefore was to assess whether Vitamin D, added to the conventional peg therapy in CHB, or to nucleotide analogues could improve the treatment efficacy

Hepatitis B is a vaccine preventable infection which can be transmitted through occupational exposure. Approximately 15% of patients will not respond to an initial series of vaccination. Of those re-vaccinated approximately fifty percent will respond. On the basis of poor response to a third series, repeat vaccination is not recommended and non-responders are considered vulnerable to infection. Cardell studied the use of double dose combination hepatitis A and B vaccine (Twinrix) in non responders who had received four or more doses previously and found a high response rate suggesting this vaccine and dose could be effective. The investigators study seeks to duplicate the findings of Cardell, using a more strict definition of non-responder (6 or more previous doses).

Chronic HCV infection is one of the common causes of the chronic liver disease. Approximately 6-10% of the general public is expected to be suffering from this infection. In case that these patients are not treated at an appropriate time, these patients develop the sequelae of the chronic liver disease e.g. cirrhosis of liver, Ascites, and Hepatocellular carinoma. Interferon alpha 2 a or alpha 2b injections and Ribavirin combination is the treatment of choice for people suffering from Chronic HCV infection and this combination need to be administered for 6-12 months. Interferons are biological agents and are to be administered parenterally. Interferons are expensive and are associated with number of minor and major adverse effects. Ribavirin is also associated with significant adverse effects. These compounds cannot be considered as one of the ideal forms of the treatment. In the past, quite a few natural products have been tested to assess their hepatoprotective activity and possibly anti viral activity as well. These include Vitamin C (Ascorbic acid), Vitamin E, Zinc, Silymarin, Red beet roots, crushed licorice and etc. etc. Rationale Iodine , Potassium iodide and Ascorbic acid are natural products used in the management of Thyroiditis and chronic cutaneous fungal infections. This combination of iodine compounds along with ascorbic acid is being used for the management of chronic hepatitis B & C in the central Asian states e.g. Kazakhstan etc. The investigators have conducted a feasibility study in which oral Iodine Compound {RENESSANS} was given to patients suffering HCV related Chronic Active Hepatitis and anti-viral activity and safety has been analyzed. In this study, RENESSANS containing regimen has been well tolerated by all the patients and has shown some antiviral activity. In this study the investigators will assess whether the administration of RENESSANS {oral } improves the antiviral activity in patients receiving standard interferon therapy.
