Active clinical trials for "Hepatitis C"

Conduct a randomized controlled trial (RCT) to test the hypothesis that offering client-centered HIV counseling and testing (HCT) to blood donor candidates will reduce the risk of HIV contamination in the blood supply and also increase appropriate referrals to preventive and care services to persons in need in São Paulo, Brazil.

With the improved prognosis of human immunodeficiency virus (HIV) infection, end stage liver disease due to hepatitis C (HCV) now represents a major cause of morbidity and mortality in people with HIV. Treatment for HCV has become increasingly important as a means of preventing the consequences of chronic HCV infection. Paradoxically, co-infected patients have low rates of treatment initiation and completion in large part because they have a high risk of developing neuropsychiatric symptoms while receiving PEG-interferon (PEG-IFN). There are a large number of co-infected individuals in Canada who could benefit from HCV therapy if tolerability could be improved. This trial will address whether prophylactic use of antidepressants in HIV-HCV infected patients initiating HCV therapy can prevent the development of neuropsychiatric side effects and thus permit more patients to receive full treatment for HCV.

A.OVERVIEW This is a 26 week study examining the ability of paroxetine (Paxil) to prevent the development of depression and neurotoxicity in patients receiving either 3 million units of subcutaneous IFN(interferon-alpha-2b) 3 times/week (plus ribavirin, 1000-1200 mg/d)) or PEG (polyethylene glycol) interferon-alpha-2b (1.5 micrograms/kg one time a week) and ribavirin (800 to 1,400 mg a day) for chronic hepatitis C (CHC). The IFN plasma half life (t1/2 of 24 to 34 hours) of PEG, a CHC treatment recently approved by the FDA, is significantly prolonged allowing for once a week dosing. Studies indicate that the side effect profile of the two forms of IFN-alpha treatment are very similar. CHC patients will be screened for study eligibility, and a total of 100 CHC patients between the ages of 18 and 65 years old will be enrolled across three sites (30 at Emory site and a combination of 30 from the University of Pennsylvania, Rush-Presbyterian-Saint Lukes Medical Center in Chicago and Montefiore Medical Center in New York.) Two weeks prior to treatment with subcutaneous IFN-alpha-2b, patients who meet inclusion and exclusion criteria will be stratified on the basis of a history of major depression and then randomly assigned to paroxetine or placebo in double blind fashion.

The purpose of this study is to compare the effects of (a) immunization setting and (b) outreach worker support on young injection drug users' (IDU) adherence to a multiple dose immunization schedule with a combined hepatitis A virus (HAV) inactivated and hepatitis B virus (HBV) recombinant vaccine.

The study is being done to study the impact of prophylactic administration of antiviral therapy as compared to initiation of antiviral therapy at the time of clinical recurrence of hepatitis C infection in liver transplant recipients.

The study will be a randomized, double blind, placebo controlled, dose rising study in Interferon alpha (IFN-alpha) non-responder HCV infected patients or HCV patients who have relapsed following IFN-alpha therapy. Eligible subjects must have compensated liver disease and serum HCV RNA concentrations above 100,000 IU/mL at screening. The study will include both a single dose period for the evaluation of acute toxicity and single dose pharmacokinetics and a consecutive multi-dose period for the determination of longer-term safety, multiple-dose pharmacokinetics and antiviral activity. The objectives of this study are to evaluate the safety, tolerability, and antiviral activity of escalating single and multiple doses of XTL 2125 in patients with chronic hepatitis C virus infection and to assess the single- and multiple-dose pharmacokinetics of XTL 2125

The purpose of this study is develop and test a cognitive-behavioral intervention to prevent depression in methadone maintenance patients receiving medical treatment for hepatitis C.

The purpose of this study is to test whether a six-session behavioral intervention for HIV and HCV seronegative injection drug users is effective in reducing sexual and injection risk behaviors that could lead to primary HIV and HCV infection.

In France, 50% of the hepatitis C virus carriers develop chronic clinical hepatitis, which may lead to cirrhosis and liver transplantation. Transplant infection by hepatitis C virus is constant after transplantation. This recurrence usually causes chronic liver disease, in 50 to 80% of the patients. The interest of a long-term treatment with ribavirin alone after transplantation has not been clearly demonstrated. The objective of our study is to evaluate the efficacy of ribavirin as a maintenance treatment after a one year interferon-α / ribavirin therapy on hepatitis C recurrence in the transplanted liver.

After a liver transplant, the hepatitis C virus (which destroyed one's own liver) eventually comes back. In many patients, this will eventually cause the loss of the new liver and can also confuse the doctors taking care of them because it is hard to tell the difference between one's body rejecting the new liver and hepatitis. This can cause serious treatment errors that can lead to more severe hepatitis or to rejection of the liver. Some of the drugs used to prevent rejection of one's new liver can cause the hepatitis to come back in a more severe form. This is especially true for the drugs known as corticosteroids. Right now, the only effective treatment against hepatitis C is a combination of two drugs called interferon and ribavirin. These drugs act by strengthening one's immune system to fight the virus and by directly reducing the reproduction of the virus. Because the treatment with these drugs is associated with many side effects, there is little experience with treating patients after liver transplantation with them. In the investigators' transplant program, they have decided to treat all patients with hepatitis C as early as possible after transplantation and to follow them closely for the development of hepatitis and side effects of the treatment. The investigators treat one's hepatitis as early as possible, before any actual damage has occurred in the new liver. This approach has been tried before but it has been hard to tell if it has worked or not. The main reason for failure was that many patients could not complete the treatment due to side effects. The investigators' purpose is to treat those side effects aggressively so that most patients can complete the treatment course. The purpose of this study is to collect all the data regarding the investigators' treatment protocol so that they will be able to learn if this form of treatment is beneficial. The study includes performing liver biopsies at scheduled times after one's liver transplant and for scheduled blood tests to see how much virus is still in the blood. If patients show signs that they are not responding to treatment they will be removed from the study.
