Filter by:Hepatic encephalopathy is the most common complication after TIPS, and hepatic encephalopathy occurs in almost all portosystemic shunts. For patients with severe upper gastrointestinal bleeding or refractory ascites in the decompensated chronic hepatitis B, transjugular intrahepatic portosystemic shunt (TIPS) is a very effective treatment. However, due to the severe complications such as hepatic encephalopathy after TIPS, the clinical application of TIPS is limited. Literature studies have shown that the incidence of encephalopathy after TIPS is about 35%. TIPS reduces the portal vena blood flow into the liver by establishing a new channel. But at the same time, the toxic substances from the gastrointestinal tract and other organs do not enter the liver to detoxify, and are more likely to enter the brain, leading to hepatic encephalopathy. Moreover, studies have found that the liver and the intestine originate from the same germ layer and are closely related to each other in anatomy and function. There are a large number of microorganisms living in the intestinal tract. Normally, the intestinal tract, as the first defense of the human body, can effectively prevent bacteria and their products from entering the bloodstream. In cirrhosis and portal hypertension, blood return disorder causes intestinal damage. A series of microbes and product endotoxins such as gram-negative bacteria will enter the blood through the injury, and the toxins in the peripheral blood will enter the brain and cause hepatic encephalopathy happened. The research team's early treatment plan with integrated traditional Chinese and Western medicine proved that it greatly reduced the incidence of hepatic encephalopathy after TIPS. And improve the clinical symptoms and signs of patients with liver cirrhosis, and improve the quality of life and survival of patients.
Hepatitis B (HBV) and hepatitis C (HCV) are prevalent all over the world, which seriously threatens public health. In 2016, the World Health Organization(WHO) put forward the goal of eliminating the threat of viral hepatitis to public health by 2030. However, at present, the diagnosis rate and treatment rate of chronic HBV and HCV in China are still far from the goal put forward by WHO. Therefore, for China, the elimination of viral hepatitis is still a public health problem that needs a long time to face. This study aims to screen and follow up HBV and HCV patients in Danzhou City, Hainan Province, so as to understand the epidemiological characteristics and long-term prognosis of HBV/HCV patients.
The anti-HBs produced after hepatitis B vaccination will decrease over time. College students are vaccinated with hepatitis B vaccine at birth, and their antibodies may have decreased significantly. In addition, college students are sexually active population, which has a high risk of HBV infection. It is necessary to study the anti-HBs level of college students, and analyze the strengthening immunization for this special group. This study will analyze the immunogenicity, immune persistence, and safety of booster dose of intramuscular 20 µg recombinant hepatitis B vaccines. Different booster vaccination including one-dose (0 month), two-dose (0, 1 months), or three-dose (0, 1, and 6 months) was given according to the antibody production level after booster vaccination among college students.
This prospective cohort study is initiated to evaluate the compliance improvement to the standardized follow-up and clinical management in the population of compensatory hepatitis B cirrhosis with a mobile health application (APP). Patients were enrolled and divided into APP self-management group (APP only ) and APP intelligent-management group (APP and online interaction). The compliance to the standardized follow-up and clinical management (every six months) under the two clinical management modes would be evaluated and compared with the history data extracted from the platform of China Registry of Hepatitis B (CR-Hep B).
In this study, treatment-naïve HBV-related cirrhosis patients were retrospectively enrolled at the first episode of decompensation (ascites or variceal hemorrhage). Patients were followed up every 6 months until death /liver transplantation or for 5 years. Clinical data from medical records about past history, first decompensated events, second /further decompensated events, HCC, and death/ liver transplantation were retrospectively collected. In this retrospective study, the incidence of re-compensation and its clinical characteristics were mainly explored.
In a population of cirrhotics patients who did not responde to an anti-HBV vaccination according to the recommended vaccination, the goal is to : Describe the proportion of patients with HBs antibody levels greater than 10mUI/mL at 1 month of the last injection of vaccine ; with a M0-M1-M6 vaccine regimen using 3 vaccines strategies : - After simple intramuscular vaccine (IM) ( Control group ) - After simple intradermal vaccine - after IMIQUIMOD's application followed by intradermal vaccine administration The main hypothesis of this study is : IMIQUIMOD acts as an immunity booster, so the combination of IMIQUIMOD with an intra-dermal injection of the anti-HBV vaccine allows better acquisition of post-vaccination immunization.
China has the world's largest burden of hepatitis B virus (HBV) infection and will be a major contributor towards the global elimination of hepatitis B disease by 2030. One of the main issues in the management of patients with chronic HBV infection (CHB) is to maximize the individuals who need the treatment engaged and retained in care. However, our investigation revealed that 21.1% patients were treatment eligible but not treated based on Chinese 2019 CHB treatment guidelines, while only 213 (13.9%) patients were indicated-but-not-treated according to AASLD 2018 Hepatitis B guidance in a real-life cohort study. To maximize the individuals who need the treatment engaged and retained in care, integrated intervention strategies to address these treatment barriers are urgently needed. Therefore, we aim to propose a study to narrow the gap between in accordance with guidelines and consent to treat CHB population in EAST of China.
To investigate the safety and efficacy of tenofovir alafenamide (orally 25 mg per day) treated in inactive chronic hepatitis B virus (HBV)-infected pregnant women with high viral load from the late pregnancy until the delivery date or postpartum 1 month.
Development of preclinical translational models for chronic liver tumors and diseases study, such as spheroids cultured in autologous medium and murine xenograft models to test the efficacy of new therapeutic strategies.
This study is an open-label, randomized, single dose, crossover study to evaluate the pharmacokinetics, safety and tolerability of CKD-388 in healthy subjects
