Filter by:Hepatitis B vaccine is a safe and effective vaccine used widely throughout the world. Because of this it is a useful vaccine in which to develop new methods for studying immune responses. Measuring the immune response to vaccines helps us to understand how they work and whether they are likely to protect any individual against infection. For most vaccines we measure the immune system's production of antibody after a vaccine has been given. The investigators want to develop new methods that give a far more detailed picture of the antibody response to vaccines than has previously been possible. These methods will investigate the genetic instructions used by each antibody producing cell to make antibody. These methods have the potential to give new insights into the way vaccines work, which could be applied to studying vaccines and vaccine schedules in the future.
After successful screening, first the investigators first treat patients of severe alcoholic hepatitis with steroids for 7 days. Patients who are found to be unresponsive as per Lille's score [>0.45] would be randomized into either placebo group or G-CSF group. Responders to steroids will continue on steroids for 28 days followed by 2 weeks of tapering. Non responders will be randomized to receive G-CSF for 28days.
The prevalence of HBsAg carriage in pregnant women varies in France, according to the native country, with highest rates in those originating from sub-Saharan Africa and Asia (5 to 8 % in Parisian area). The level of HBV-DNA varies according to HBe status and geographical origin, and is strongly predictive of the risk of HBV mother-to-child transmission (MTCT). It has been shown that the rate of vertical transmission (Chinese study by Yuan J et al) was 0 % in newborns to mothers whom HBV-DNA was < 105 copies/mL and up to more than 40 % in newborns to mothers with high viral loads > 108 copies/mL, despite HBIg and vaccine at birth. Thus, data are needed concerning the current practices about the prevention of HBV MTCT in France, and their results.
This study will compare two different treatments of acute alcoholic hepatitis. The current standard of care is treatment with corticosteroids (methylprednisolone). This will be compared to treatment with anakinra, pentoxifylline, plus zinc sulfate. The participants will be treated and followed for 6 months and the two treatment groups will be compared for differences in death rates and laboratory tests that measure liver and gut function.
Background: - GS-7977, GS-5885, GS-9669, and GS-9451 are new drugs for treating hepatitis C virus (HCV) infection. GS-7977 may help treat the infection when used with other treatments like interferon therapy. GS-5885, and GS-9669, and GS-9451 also lower the amount of HCV in the body. Researchers want to see whether GS-7977 can be combined with any of the other three drugs to treat HCV infection. Some participants will take GS-7977 and GS-5885. Others will take GS-7977, GS-5885 and GS-9669 or GS-7977, GS-5885 and GS-9451. Objectives: - To see whether GS-7977 with GS-5885 alone or in combination with either GS-9669 or 9451 can be used to treat HCV infection. Eligibility: Individuals at least 18 years of age who have chronic HCV infection and have never been treated for it. Individuals at least 18 years of age who have chronic HCV infection and have not responded to interferon therapy. Individuals at least 18 years of age who have chronic HCV infection with advanced liver disease and have never been treated for HCV Design: Participants will be screened with a physical exam and medical history. Blood samples will be collected. A liver biopsy may also be performed. Some participants will take the two study drugs and some will take three study drugs. Those who take GS-7977 and GS-5885 will have one daily tablet named fixed dose combination or FDC. Those who take GS-7977 and CS-9669 will have three daily tablets taken once daily. Those who take GS-7977 and GS-5885 and GS-9451 will take 2 pills once a day. GS-7977 and GS-5885 will be combined in one pill and GS-9451 will be in another pill. Treatment will be monitored with frequent blood tests. These tests will check liver function and the level of HCV infection. Participants may have other blood tests as needed for treatment. Participants will have 6, 8, or 12 weeks of treatment depending on which study drugs are scheduled to take. After they complete their schedule, they will stop treatment with the study drugs. They may also have another liver biopsy. Participants will have regular follow-up visits over the next 48 weeks. They will have physical exams and provide blood samples....
