Filter by:Patients with acute hepatitis C virus (HCV) infection usually become chronicity if viremia persists after 6 months of infection. The result of using pegylated interferon plus ribavirin combination therapy upon these patients remains to be explored
Hepatitis delta is a major health problem, not only because of the severity of the disease, but also due to the lack of effective antiviral treatment. To improve the current therapeutic options, a better understanding of the pathophysiology is essential. Reliable research in this direction is only possible with large patient study groups. However, given the geographic distribution of hepatitis delta, larger patient cohorts would only be possible through multicenter collaboration.
Fulminant hepatic failure (FHF) in children is a potentially devastating disease. The mortality rate may reach 80-90% in the absence of liver transplantation. Liver injury is considered to be mainly immune mediated with augmentation of cytolytic pathways of infected hepatocytes. For that, it is suggested that corticosteroids modulate the activity of the disease by suppressing the immune system.
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: 1. Treatment-naïve patients, with and without cirrhosis (Group 1) 2. Previous non-responders to interferon-based therapies, without cirrhosis (Group 2) 3. Previous non-responders to interferon-based therapies, with cirrhosis (Group 3)
The study aims to collect information on the current treatment patterns for Hepatitis C in participating countries. There is also a focus on patients receiving a daclatasvir-containing treatment regimen who will be followed prospectively for 12 months after treatment initiation to collect real-world data on effectiveness and safety of the treatment. Additional analysis will differentiate between selected subpopulations.
The aim of interferon therapy in HBeAg positive chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as occurred HBeAg seroconversion and HBsAg loss with sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after withdraw of treatment. In this trail, Nucleoside(acid) analogues(NA) will add on patients with HBV DNA load ≥1000copies/ml after 6 months of interferon treatment, and the efficacies of the combine therapy were evaluated by the rates of HBeAg seroconversion and HBsAg loss after 48 weeks of combined therapy, compared with control group.
The prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) in the United States (US) is relatively low. However, immigrant populations in the US from Asia and sub-Saharan Africa have substantially higher prevalence than the general population and are consequently at a significant risk for hepatocellular carcinoma (HCC). Indeed, the age-adjusted incidence rates for HCC in the US have tripled from 1975 to 2005. As the population demographics have changed, the 2000 US census estimated the number of Somalis in Minnesota at 25,000 but current estimates put the number at around 50,000 due to primary refugee arrivals as well as secondary immigration from other states. There is no available data for Somali immigrants in the US on HBV and HCV prevalence, HBV and HCV genotypes/subgenotypes, and genetic and immunologic risk factors predisposing Somalis to HBV and HCV and the subsequent development of HCC. Therefore. this study will fill these gaps in the Somali population to understand the relative importance of HBV and HCV infections in causation of HCC. Besides Somalis, Minnesota is also home to large other African immigrant communities. According to the Minnesota Department of Health (MDH), in 2013, the highest rates of chronic HBV cases where reported among Asian or Pacific Islanders (3,638 cases per 100,000 persons) followed by Black or African Americans (2,078 cases per 100,000 persons). Additionally, Minnesota receives a large number of new refugee's resettlement. It is important to improve the identification of chronic HBV and HCV infections among Somali refugees and immigrants in Minnesota through well-designed community-wide screening efforts. Since we know that African immigration to Minnesota is the third highest in the US, this unique population might be a contributing factor to the increased burden of hepatitis and liver cancer complications in the state of Minnesota. Findings from HBV and HCV screening among Somalis suggest that other immigrant African populations from high viral hepatitis endemic regions, such Ethiopia, Liberia, and Kenya, are also at substantial risk of HBV, HCV and HCC. Unfortunately, very little research has been conducted in the US on the burden of hepatitis and liver cancer in African Immigrants from areas of high endemicity of hepatitis B and hepatitis C. Therefore, the goal of is to identify HBV and HCV and the role viral genetics and immune response among African immigrant communities from Kenya, Liberia, and Ethiopia.
This trial is to assess the efficacy and safety of Polyethylene Glycol thymosin alpha1 (PEG-Tα1), a new long immunomodulator (Category 1.1 of Chemical Drugs) being developed from Hansoh Pharmaceutical of China, in combination with adefovir in HBeAg-positive patients with chronic hepatitis B.

The aim of interferon therapy in HBeAg negative chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after treatment withdraw. In this trail, entecavir will add on patients with HBV DNA load ≥1000copies/ml after 3 months of peginterferon alpha 2a treatment, and the efficacies of the combine treatment will be evaluated by the rate of sustained viral response after 48 weeks of treatment and 24 week follow up.
