Filter by:There will be 124 patients diagnosed as hepatitis B associated acute on chronic liver failure with mild to moderate hepatic encephalopathy will be enrolled in this study according to the inclusion and exclusion criteria, and will be randomly divided into two groups as 1:1.First group is called Rifaximin group, on the basis of comprehensive treatment of liver failure, Rifaximin (Alfa Sigma S.p.A) is added, three times a day, 400 mg each time, for a total of 4 weeks, and observed until 12 weeks after withdrawal. The other group is called standard treatment group (control group), which will receive routine comprehensive treatment for liver failure. The reversal of mild to moderate hepatic encephalopathy in the two groups of patients will be observed within 4 weeks, then follow up to 12 weeks.
The objective of this observational study is to evaluate the clinical utility of the combined assay of 3 biomarkers: α-FP, α-FP-L3 and DCP (simultaneously measured by µTASWakoTM i30 automated in vitro diagnostic system) in high-risk subjects to develop this neoplasm. In particular, it aims to: - Evaluate the clinical utility of the combined use of α-FP, α-FP-L3 and DCP in predicting the onset of HEPATOCARCINOMA (HCC); - Evaluate the performance of GALAD and GALADUS scores in the early diagnosis of HCC; - Evaluate the association between the levels of the three biomarkers (individually and in combination with each other) and the stage of HCC
In summary, with the help of single-cell sequencing technology, this study aims to focus on elucidating the influence of HBV-induced hepatocellular carcinoma cell metabolic changes on microenvironment remodeling. With the help of hepatocellular carcinoma microenvironment changes, this study provide a more accurate diagnosis and treatment method for HBV-induced hepatocellular carcinoma.
The aim of this study was to developed and validated models to predict hepatic decompensation and survivals in pediatric patients with cirrhosis and compared these models with currently available models.
The objective of this protocol is the collection and testing of clinical samples to determine the clinical performance of the Access HBV serological marker assays on the DxI 9000 Access Immunoassay Analyzer. The study will involve a multicenter, prospective and retrospective collection of samples, and testing of samples with the investigational Hepatitis B Virus assays as required per the European Union Common Technical Specification. All samples collected will be anonymized or pseudo-anonymised, leftover, remnant samples. Pseudo-anonymised collection of samples will require documented patient consent (oral or written).
The aim of this study is to compare the BW and metabolic profiles of CHB patient before and after shifting to TAF therapy. In this study, investigators will enroll 100 entecavir and 100 TDF treated CHB patients who will switch to TAF and then follow for one year. Demographic, liver function tests, sugar profiles, lipid profiles, ASCVD risk score, body weight, body weight, body height, and waist circumference will be checked and recorded periodically. Investigators anticipated that body weight will change significantly after switching to TAF in both entecavir and TDF group and may associated with increased risk of cardiovascular risk.
TAF is a new prodrug of tenofovir, specifically designed to achieve higher intracellular active drug concentration allowing for dosing of only 25 mg once daily and thus can potentially lower the already relatively low risk of renal toxicity and bone loss with TDF. However, such renal and bone complications with TDF may become more pronounced in decompensated CHB patients10. In the phase 3 trials11, 12, TAF had demonstrated a compatible antiviral effect (noninferior efficacy), and a higher rate of alanine aminotransferase (ALT) normalization to TDF. TAF also demonstrated an improved renal function and less bone loss compared to TDF. Therefore, TAF was approved as the first line therapy for CHB patients with compensated liver function. The lack of data regarding TAF therapy in decompensated CHB patients raised the concern of safety and efficacy of TAF in this group of patients. A small, single arm Phase 2 switch study (GS-US-320-4035; Study 4035; NCT03180619) which has enrolled 31 subjects with CPT scores ≥7, either at time of screening or by history, who were virally suppressed on TDF and/or other oral antiviral agents is currently underway with favorable safety and efficacy results through 48 weeks.[Lim YS, Lin CY, Heo J, et al. EASL 2020, poster SAT442.] While Gilead Study 4035 will continue through 96 weeks of treatment, additional data in this population are thus needed, particularly in CHB patients who have decompensated liver disease and are not being treated and are viremic. Herein, we conduct the present study and aim to investigate the safety and efficacy of TAF in CHB patients with hepatic decompensation.
This study is a multicenter, open-label, phase II clinical study in subjects with chronic hepatitis B (CHB), to characterize the safety, tolerability, pharmacokinetic profile and preliminary anti-hepatitis B virus (HBV) efficacy of APG-1387 in combination with entecavir, and to determine the optimal dose of APG-1387 in combination with entecavir.
This is a multicenter, prospective, observational study to compare the efficacy and safety of stratified prophylaxis based on donors' and recipients' risk factors vs routine prophylaxis bases on clinical experience in living kidney transplantation from HBsAg+ donors to HBsAg- recipients. The follow-up period was 2 years after renal transplantation. The primary outcome was prevention failure of HBV transmission (any one of HBsAg - → +, HBV DNA - → +, HBeAg - → +, HBeAb - → +, HBcAb - → +, active liver function damage and death in the recipient).
This is a prospective, single-center, open-label, randomized controlled trial aimed to evaluate the efficacy and safety of entecavir and tenofovir versus entecavir alone in the antiviral treatment of HBV DNA positive B-cell lymphoma patients. This study plans to enroll about 120 participants in total. Recruitment will last for 2 years. The study visit will take place on the first day of each cycle of therapy until the end of the treatment. Participants who meet the inclusion/exclusion criteria were randomly assigned to receive entecavir and tenofovir or entecavir alone after signing the informed consent. HBV DNA will be measured before each cycle of chemotherapy or immunotherapy. When the copy count of HBV DNA drops below 1*10^3/L, entecavir single agent will be given orally, until one year after the cycle of therapy. Treatment response will be evaluated routinely after chemotherapy or immunotherapy. Within 2 years after the last participant is enrolled, participants' survival information will collected by telephone and/or clinical visit every 3 months after the last visit (i.e. date and cause of death, subsequent cancer treatment, etc.), if there is no withdrawal of the informed consent form.
