Filter by:To demonstrate the effectiveness of DCV 3DAA fixed dose combination with or without Ribavirin in treatment naive cirrhotic subjects.
This study will explore the relationship of different DEB025 doses in combination with RBV to pharmacokinetic, pharmacodynamic (i.e. viral load reduction) and safety profiles in chronic hepatitis C GT 2 and 3 treatment naïve patients.
This trial studies hepatitis B screening strategies of new cancer patients scheduled to undergo chemotherapy. Patients with cancer and hepatitis B virus infection are at risk of reactivation of infection after chemotherapy. Hepatitis B virus infection reactivation can be prevented by starting antivirals before chemotherapy in patients who are hepatitis B virus infection positive. Hepatitis B screening may help doctors prevent the reactivation of hepatitis B virus infection after chemotherapy.
Hypothesis: Oral administration of hyperimmune bovine colostrum enriched with anti-LPS antibodies will reduce endotoxemia, and improve pathophysiological and clinical parameters related to severe alcoholic hepatitis (SAH). IMM 124-E is safe in subjects with severe alcoholic hepatitis being treated with steroids. Aim: To perform a phase 2a "proof of concept" placebo-controlled, dose-ranging study of Imm 124-E (hyperimmune bovine colostrum enriched with IgG anti-LPS) in subjects with severe AH on steroids.
The aim of our prospective study is to construct and validate a non-invasive model consisting biochemical markers, FibroScan, and radiological parameters for evaluating liver fibrosis caused by hepatitis B virus in mainland China.
This multi-center observational study examines risk factors for HCV transmission from mother to baby.
This study is designed to support the optimal use of telbivudine by providing data to refine our understanding of telbivudine efficacy and resistance in real life clinical setting in patients with chronic hepatitis B with defined baseline characteristics and 24-week PCR negativity.
Hepatitis B virus (HBV) infection is a global health problem, especially in the endemic area like Taiwan, where there are more than 3 million chronic hepatitis B carriers. Patients with chronic HBV infection are at increased risk of developing cirrhosis, which may have disastrous complications, including hepatic decompensation, and hepatocellular carcinoma (HCC). The liver cirrhosis related complications accounts for the 8th leading cause of deaths in Taiwan; whereas, the HCC is the 2nd leading cause of deaths among all cancers. Therefore, it is prudent to develop strategies to prevent or halt the progression of liver cirrhosis. For HBV patients who have already had cirrhosis, the main treatment objective is to reduce their risk of complications. A large-scale multicenter clinical trial showed that viral suppression using lamivudine in patients with advanced fibrosis effectively decreases the risk of HCC and liver-related complications. This study highlights the importance to treat HBV-related cirrhosis patients; however, several issues remain to be addressed. The first issue is that this clinical trial only enrolled patients with positive HBeAg or HBV-DNA level >1.4 x105 IU/mL. However, the current recommended threshold for cirrhotic patients to start anti-viral treatment is 2000 IU/mL. Whether anti-HBV therapy benefits cirrhotic patients in this level is still unclear. Second, lamivudine was used in this clinical trial; however, the high resistant rate of lamivudine during treatment probably lowers its protective effect against HCC. Whether a more potent anti-HBV agent with extremely low resistance profile, entecavir, is more beneficial to HBV-related cirrhotic patients is also unclear. The Bureau of National Health Institute launched the reimbursement program for anti-HBV therapy since 2003 and extended this program to cirrhotic patients with HBV DNA level > 2000 IU/mL for long-term use since Aug, 2010. Taking this advantage, we may explore the above-mentioned clinical questions more easily. To address these issues, we will first retrospectively collect a cohort of HBV-related cirrhosis patients. All the patients will be enrolled from the time before oral anti-HBV therapy is widely used. We will determine their baseline serum HBV-DNA levels using the stored sera and enrolled those with baseline HBV-DNA levels higher than 2000 IU/mL as our historical controls. Second, we will enroll a retrospective cohort of HBV-related cirrhotic patients from 2008 who had HBV-DNA levels higher than 2000 IU/mL and received indefinite therapy of entecavir. By comparing these two cohorts, we will be able to clarify whether indefinite viral suppression by entecavir is beneficial for the cirrhotic patients. With comprehensive analysis, we wish to document that re-setting the risk level of HBV DNA from 140,000 IU/mL to 2,000 IU/mL is more beneficial for HBV-related cirrhotic patients and long-term entecavir does lower the risk of HCC further. These lines of evidence will assist in delivering appropriate and more aggressive treatment for these high-risk patients.
The Centers for Disease Control and Prevention estimates that there are approximately 3.2 million people in the United States infected with hepatitis C and a significant percentage of these patients are unaware of their diagnosis. This study will attempt to determine the point prevalence of undiagnosed hepatitis C infection in an urban hospital population. All patients admitted to the hospital on two separate days will have hepatitis C testing done on leftover serum and plasma that was collected as part of routine inpatient lab work. Our primary goal is to determine the number of undiagnosed hepatitis C infected patients in our hospitalized population. We will also compare these rates to specific demographic characteristics, such as age, race, gender, zip code and type of insurance to see if any associations exist between these demographics and undiagnosed hepatitis C infection.
- The cohort will integrate clinical, genetic, pharmacogenomics, environmental, biomarkers and behavioral data in a large number of patients and will be a leading equipment for crossdisciplinary and translational research on hepatitis. - The cohort will be the main support for estimating the relative effects of treatments and for further cost-effectiveness studies on the management and treatment options in chronic HCV (Hepatitis C Virus)and HBV (Hepatitis B virus)infections.
