Active clinical trials for "Hepatitis A"

The study will assess the efficacy of PPI-668 (USAN: ravidasvir hydrochloride) in combination with sofosbuvir, with or without ribavirin, in the following Egyptian HCV gt-4 patient populations: Treatment-naïve patients, with and without cirrhosis (Group 1) Previous non-responders to interferon-based therapies, without cirrhosis (Group 2) Previous non-responders to interferon-based therapies, with cirrhosis (Group 3)

Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, cytokines played a vital role. This study was aimed at investigating the changes of cytokines during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, the investigators wanted to verify whether Peg-IFN-α therapy resulted in the secretion of cytokines.

This trial will study the effect of a polyherbal capsule in lowering the viral load of patients with chronic Hepatitis B infection and record the incidence of from Hepatitis B surface antigen elimination in 12 months

Since the implementation of universal vaccination in 1984, the chronic HBV carier rate in our general population reduced from 15-20%, down to < 1% in the post-vaccination population. However, children born to HBeAg positive mothers still may be infected with HBV despite immunization. To further reducing the HBV infection in our people, strategies in reducing infection rate in this high risk group are mandatory. Previous small scale studies using lamivudine treatment in pregnant woman in the third trimester has proved effective in reducing children infection rate. The aims of the present study are to conduct a clinical trial in using Tenofovir (category B) to reduce mother-to-infant transmission, and to monitor the hepaitits B viral status and mother hepatitis occurrence. The clinical trials will screen cases of HBsAg positive pregnant women aged 20 to 40 years at gestational at 20-32 weeks. They will be tested for HBsAg and HBeAg. In whom both markers are positive, HBV viral load will be tested. An estimated 180 pregnant women with high HBV viral load (>10^8 copies/mL) will be recruited in the study; including 80-100 subjects treated with Tenofovir 300 mg daily starting from 30-32 weeks of gestation (3rd trimester) and continued to 1 month after delivery; and 80-100 pregnant women are enrolled as controls with no drug given to the mother. The newborn babies are given with HBIG within 24 hours after delivery, and HBV vaccines at 0, 1 and 6 months. Maternal complete blood count (CBC) data tested in the first prenatal examination will be recorded. Plasma AST、ALT levels and HBV DNA are tested before Tenofovir treatment, 1 month after treatment, at the time of delivery, and at 1, 2, 4 and 6 months after delivery. HBsAg、HBeAg、anti-HBs and AST、ALT are tested in the children at day 1, 6 moths and 1 year after birth. The primary outcome is reduction of the HBsAg carrier rate of the children at 6 months of age. The secondary outcome is HBsAg carrier rate of the children at 12 months of age, the change of liver function, HBeAg, and viral load in pregnant mother after treatment. A follow-up study for investigating safety of mothers and children that has been exposed to maternal tenofovir disoproxil fumarate (TDF) during pregnancy in reducing mother-to-infant hepatitis B virus (HBV) transmissions is conducted. The follow-up study included mother-children pairs 2-4 years after delivery of the children.

The investigators will investigate the clinicopathological features of chronic hepatitis B patients with severe exacerbation selected by uniform criteria, and treated with early introduction or reintroduction of corticosteroids and anti-allergenic therapy, in order to clarify the benefits and limitations of the effects of corticosteroids and anti-allergenic therapy for amelioration of clinically severe exacerbation of chronic hepatitis B. The investigators also observe the immune index in the change before and after the treatment, in order to searching for some prognostic index.

Hypothesis Combination of Boceprevir with Ribavirin in treatment-naïve patients with genotype 4 chronic hepatitis C infection will increase the proportion of patients achieving sustained viral response compared to standard treatment alone.

Chronic hepatitis C is endemic in Egypt with a high prevalence of the resistant genotype 4. Conventional standard of care treatment has modest response with only 50% sustained virologic response. Recent reports have suggested an augmented response with the addition of vitamin D. This is a prospective randomized trial to assess the effectiveness of adding vitamin D to standard of care for chronic hepatitis C genotype 4.

The purpose of the study is to determine how effective preemptive tenofovir therapy is in preventing the re-activation of Hepatitis B infection, in patients who are receiving rituximab-based chemotherapy for Non-Hodgkin's Lymphoma or CLL/SLL. The rate of re-activation will be compared between patients who receive preemptive tenofovir and patients who receive tenofovir as needed.

Entecavir (ETV) has shown superior ability to suppress hepatitis B virus (HBV) replication, histology improvement as well as low rate of emergence of resistant mutants. Out of range of clinical recommendations for treatment of chronic hepatitis B (CHB), chronic HBV carriers with persistently normal ALT and viral load more than 10^5 copies/mL have progression of liver disease during long-term follow-up. In addition, certain proportions of these patients do have significant inflammation and fibrosis in liver histology. This study will be able to identify who are at risk of liver disease progression and evaluate efficacy of ETV regarding improvement of liver histology during short-term (1-year) and long-term ETV treatment (3-year).

The purpose of this study is to assess the long-term persistence of immunity to hepatitis A and B in adults who were vaccinated 16-20 years earlier with the combined hepatitis A and hepatitis B vaccine, Twinrix.
