Filter by:The study aims to demonstrate that antiviral therapy for patients with immune tolerance of CHB. On the basis of the original antiviral therapy of entecavir, further clarify the safety and effectiveness of entecavir combined with tenofovir amibufenamide.The investigators plan to enroll about 328 hepatitis B patients,. who are in the stage of immune tolerance. These participants will be devided into two groups randomly .Group A will receive the treatment of entecavir. Group B will be treated with entecavir and tenofovir amibufenamide. The participants in both groups will be followed up for 96 weeks. The primary endpoint is to compare the inhibition rate of HBV-DNA between two groups. The secondary endpoint includes: (1) Comparing the decrease of HBV DNA at 48 weeks between the two groups. (2) Comparing the HBeAg seroconversion rates at 48 weeks and 96 weeks between the two groups. (3) The changes of HBsAg at 48 weeks and 96 weeks between the two groups. (4) Comparing adverse side effects between the two groups.
This study aims to investigate the efficacy and safety of avatrombopag for treating thrombocytopenia in hepatitis b virus related acute-on-chronic liver failure patients receiving artificial liver support system treatment.
BACKGROUND It is estimated that around 71 milion people live with chronic hepatitis C virus (HCV) infection. This may lead to the development of liver cirrhosis and hepatocellular carcinoma (HCC). Liver cirrhosis is considered as one of the most common risk factors of hepatocellular carcinoma (HCC). HCC is seventh most common cancer worldwide. The treatment of HCV with direct-acting antivirals (DAAs) has led to the increase of sustained virological response (SVR) rates to more than 90%. It is suggested that the virus eradication reduces, but not eliminates the risk of HCC. This concerns especially patients with liver cirrhosis or previous HCC history. There are reports of early occurrence of HCC after the DAA treatment. Therefore, patients undergoing successful HCV treatment should be monitored for the possibility of hepatoccelular carcinoma occurrence. AIM OF THE STUDY In this study the investigators aimed to assess the occurrence of HCC after direct acting antiviral HCV treatment and evaluate whether the course of HCC and liver function differ among the population of patients treated with DAAs and those who were not receiving the therapy with DAA. MATERIAL AND METHODS This is the observative, cohort, retrospective study which will be performed in several clinical centres in Poland. The inclusion criteria are: hepatocellular carcinoma diagnosis, age >18 years old. The investigators will collect both epidemiological (age, gender, comorbidities, alcohol abuse) and clinical data (serum bilirubin, alanine, aspartate aminotransferase, platelets, gammaglutamyltransferase, alkaline phosphatase and alpha-fetoprotein level, Child-Pugh and MELD score, imaging tests, liver biopsy and elastography, if performed). In all patients, the HCV infection and co-infections will be assessed. In those who underwent the DAA treatment, the composition of the therapy and response to the treatment will be evaluated. Statistical analysis will be performed in subgroups of patients undergoing DAA treatment and without the therapy. The distribution of continuous variables will be analysed by the Shapiro-Wilk test. Quantitative data will be analysed using the Mann-Whitney U test or Kruskal-Wallis ANOVA when appropriate. Qualitative data will be compared using the χ² test or the Fisher exact test. Correlations between quantitative variables will be assessed using the Spearman correlation coefficient. P value will be set at <0.05.

Refractory hepatitis B is to point to although standard application nucleoside (acid) analogue treatment undertakes primary treatment and two strengthen treatment, but existence is persistent viremia. Currently, there is no consensus on salvage therapy for patients who remain virus-positive after a second round of antiviral therapy. This is the first multicenter, prospective, parallel controlled, open-label cohort study to compare the efficacy and safety of TDF/TAF combined with ETV1.0mg regimen versus continuation of the original regimen in the treatment of refractory hepatitis B.
Patients with hepatitis c showed increased level of oxidative stress. Increased level of serum lipid peroxidation leads to the production of toxic mediators as malondialdehyde (MDA) which lead to disease progression. Chronic stress shunt tryptophan which is essential amino acid toward kynurenic pathway leading to lower level of serotonin and melatonin level. Currently, direct-acting antivirals (DAAs) show well-established efficacy against hepatitis C virus (HCV).
Clinical interventions to reduce the risk of vertical transmission of hepatitis C virus (HCV) infection from mother to infant are highly limited. Direct-acting antiviral (DAA) medications have demonstrated excellent safety and efficacy in non-pregnant individuals, but there is a lack of data regarding the safety of these medications in pregnant women and the effectiveness of these medications in reducing mother-to-child transmission. Therefore, although HCV screening during pregnancy is now recommended in many countries, there is no approved treatment for HCV during pregnancy. An observational study is here proposed to assess outcomes of mother-infant pairs exposed to DAAs during pregnancy within a global clinical case registry. Data regarding the exposures and outcomes of mother-infant pairs exposed to DAAs during pregnancy will be solicited and collected from clinical providers, healthcare facilities, HCV treatment programs, and other clinical practices worldwide. Data will be shared and maintained within a secure database, and cumulative data will be analyzed at pre-determined six-month intervals. The primary outcome will be the number and proportion of mother-infant pairs with adverse pregnancy or birth outcomes. The results of this study will inform HCV treatment decisions by clinical providers and programs worldwide.
The principle is to propose dedicated monthly screening days bringing together the health personnel involved (hepatologist, addictologist, nurse in charge of the program, addictology nurse and social worker) and to propose appropriate management for each situation assessed.
Chronic hepatitis B seriously endangers the health of our people, especially the occurrence of HCC, which brings huge economic burden and life threat to our people. 84% - 92% of HCC in China is related to chronic HBV infection. How to further reduce the risk of liver cancer is an urgent problem to be solved in clinical research and an important direction. Although NAs treatment can make patients achieve the negative transformation of virus, it can not effectively reduce the level of virus antigen, and it also lacks the ability to improve the immune clearance of virus. As a result, the incidence of liver cancer in patients with long-term NA treatment is still 4.5% - 10.5%, and the incidence of HCC in patients with hypoviremia in Na treatment is higher. In current clinical practice, nearly 1 / 3 of patients treated with NAs can not reach the detection line of highly sensitive reagent. It is an important measure to make the patients with hypoviremia and inactive low virus replication treated by NAs below the detection line of highly sensitive reagent and further reduce the risk of HCC. However, it is still not enough to minimize the risk of HCC to achieve a complete viral response only through NA treatment. The long-term follow-up showed that the incidence of HBsAg disappeared by only 2.0% - 0.0% regardless of the long-term treatment of HBsAg. Therefore, the most important measure to minimize the occurrence of HCC is to optimize the treatment of NA treated patients with low virus replication and inactive patients with low virus replication to achieve complete virus response and clinical cure. The purpose of this study is to explore the optimal treatment scheme for chronic hepatitis B NA treated patients with hypoviremia and natural low virus replication patients to significantly reduce the risk of HCC.
