Filter by:The investigators will evaluate the efficacy of high dose vitamin C in chronic hepatitis patients whose serum liver enzymes are elevated more than upper limit.
Despite the availability of effective anti-tuberculosis agents that exist to treat this illness, hepatotoxicity during first-line drugs anti-tuberculosis medications (ATT) such as isoniazid (INH), rifampin (RIF), and pyrazinamide (PZA) is not uncommon and limit their use. There is no consensus on method of the reintroduction of anti-TB medications. The risk of reintroducing of a anti-TB medications could be hazardous. There are several differences between the guidelines from the ATS, BTS and the Task Force of the European Respiratory Society, the WHO and the International Union Against Tuberculosis and Lung Disease about the methods of reintroducing of anti-TB medications. The investigators plan to do a prospective study to evaluate the outcome and safety of reintroduction of anti-TB medications after resolution of hepatitis during anti-TB treatment among TB patients in the investigators hospital.
Antiviral treatment on Chronic Hepatitis B (CHB) patients with liver cirrhosis is compulsory and effective. Telbivudine, which is superior to lamivudine in the treatment of CHB,is considered to be appropriate for the antiviral treatment on CHB patients with liver cirrhosis.
This is a multi-center cohort study in which the Real-time Tissue Elastography® measurements will predict prospectively the incidence of hepatocellular carcinoma, the incidence and severity of gastroesophageal varices ascites and decompensated cirrhosis in hepatitis B or C patients.
This is a multi-center cross-sectional study in which the Real-time Tissue Elastography® measurements will be collected prospectively from patients with chronic hepatitis B or C virus presenting for liver biopsy.
The aims of this study are to determine: 1. the degree of immunity against hepatitis B, 2. factors associated with immunity against hepatitis B, 3. if the amount of antigen provided in a booster dose (used to measure the degree of immune memory) affects the body's response to the booster, and 4. if the age at which the vaccination was initiated during infancy affects duration of protection against hepatitis B among adolescents 16-19 years of age born in the United States who were immunized against hepatitis B as infants. These data will be important to evaluate the potential need for a possible booster dose of hepatitis B vaccine among adolescents. Study subjects eligible for enrollment will: - have blood drawn for baseline serologies - receive the hepatitis B booster dose (randomly determined to be either a 10 ug or 20 ug dose) - have blood drawn again 14 days later to determine if the booster dose has engendered an anamnestic response (a response attributed to prior immunity rather than a new response to the vaccine) The primary hypothesis is that the majority of young people will exhibit immune memory for hepatitis B in response to a booster dose of vaccine.
To explore the effect on early viral kinetics and viral load, and to determine safety, tolerability and anti-viral response for the plasmid DNA vaccine CHRONVAC-C administered i.m. in combination with electroporation followed by standard of care (SOC) in treatment naïve chronic HCV genotype 1 patients.
The objective is to assess the efficacy, dosing, safety and tolerance of Y- shaped pegylated interferon (YPEG-IFNα-2a) plus ribavirin in Egyptian patients with chronic hepatitis C and with no prior treatment for hepatitis C virus (HCV). Methods: Randomized, Open-label trial, in 3 parallel groups (each of 100 patients)
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.
More recent studies have shown that the HBV-infected population has a greater risk of development of hepatocellular carcinoma. Nevertheless, there are still a significant number of people chronically infected by HBV who do not develop the complication. Hence, there exist biological markers that could be indicator for the disease-inducing and carcinogenic potential of the virus.
