Filter by:HBeAg-negative chronic hepatitis B (CHB) patients with low Level HBsAg were enrolled. After giving informed consent, patients were treated with nucleoside analog(s) (NAs) once a day and weekly subcutaneous injections of peginterferon alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week for 12 weeks. At week 12, the decrease of HBsAg was evaluated. ①If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/ mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. ②If the decrease of HBsAg is less than 50% compared to baseline level. The combination therapy of NAs and peginterferon alfa was extended to week 24. Then, the decrease of HBsAg was evaluated again. If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. If the decrease of HBsAg is less than 50% compared to baseline level. Peginterferon alfa was stopped, patients were treated with NAs once a day and then followed up for 48 weeks. Patients who maintained the original NAs treatment served as a control group.
A total of 80 adult chronic hepatitis B patients with advanced liver fibrosis (including fibrosis stage 3 and cirrhosis), who are currently on nucleot(s)ide analogs (except tenofovir alafenamide) therapy with detectable HBV DNA after 52 weeks of therapy will switch prior NUCs to TAF 25 mg/day for 96 weeks
The study is looking at the potential of utilizing a "point of care" test and treat pathway; using the DDA called Zepatier for achieving SVR in an homeless population who have tested positive for genotype 1 or 4 HCV.
The primary objective of this study is to evaluate the efficacy and safety of fixed dose combination (FDC) bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in adults coinfected with both HIV-1 and hepatitis B. As this is a switch study, all eligible subjects enrolled will be switched from their current antiretroviral regimen to B/F/TAF will be followed on treatment for 48 weeks.
HBV(hepatitis B virus) /HCV(hepatitis C virus) co-infection may accelerate liver disease progression and increase the risk of HCC(Hepatocellular Carcinoma)development. It is reported HCV co-infection harmfully affects liver fibrosis in HBV patients, while decompensated cirrhosis is increased in co-infected patients compared with HBV- or HCV- mono-infected patients. One meta-analysis having pooled 39 studies performed in China reported that around 5% of HCC was associated with HCV infection alone and 6% with co-infection of HBV + HCV. However, the exact prevalence of HCV infection in HBsAg(Hepatitis B virus surface antigen)(+) cohort is actually unknown. It is estimated to be between 0.7% and 16%, a percentage that varies over a wide range among several studies from literature, mainly depending on different geographical distribution and study population. However, in regions where HBV is endemic, such as China with a HBsAg positive rate of 7.18%, the probability of co-infection increases due to a similar transmission route, especially in patients with high risk of HCV infection, like dialysis, HIV infection, organ transplantation, sex workers, drug abuser, tattoo, piercing, blood donation, history of scaling or dental filling, HCV family history and so on. As for China, the awareness of HCV infection is much lower than HBV because the occult of HCV infection, also because governments as well as medical authorities didn't input enough resources to disease education. Up to now, the national HCV elimination in China is daunting because of barriers in HCV awareness/link to care, and lack of well-established strategies. On the contrary, HBV infection has been widely known and educated to general population. As an add-on benefit, it might be relatively easier to conduct HCV screening test among those HBsAg-positive population. HCV elimination in high-risk subgroups from the basis in HBV population can be achieved with greater possibility and such model could be further shared to health care societies.
To Identify the collected cases who can stop NAs safely with satisfactory clinical outcome including sustain viral remission and HBsAg clearance among chronic hepatitis B(CHB) patients.
Hepatitis C virus (HCV) infects an estimated 185 million individuals worldwide and 3.4 million to 4.4 million people in the United States. Approximately 80% of acutely infected HCV patients progress to chronic infection, 20% of whom develop cirrhosis within 25 years, with 25% of patients with cirrhosis developing hepatocellular carcinoma and/or decompensated liver disease. Hepatitis C virus is the primary cause of liver transplantation in the United States. There are 6 known genotypes of HCV. The most common genotypes in the United States are genotype 1 (subtypes 1a and 1b), 2, and 3, which together comprise 97% of all infections. In chronic kidney disease (CKD) patients, the prevalence of HCV infection is higher than in the general population. Patients with impaired kidney function have limited therapeutic options. The US Food and Drug Administration (FDA) recently approved Elbasvir/Grazopevir for treatment of genotype 1 and 4 infection in CKD patients including those on hemodialysis. At our institution, the Multidisciplinary Approach to the Treatment of Chronic Hepatitis C (MATCH) Initiative is a program which was first implemented to increase screening, diagnosis and treatment of HCV by actively incorporating primary care providers (PCP) at every step of the HCV care process. Following implementation of MATCH, early data indicates, marked increase in screening high risk and baby-boomer cohorts, as well as safe and effective treatment of HCV cases at the primary provider setting. The initiative proved that active participation of PCPs in the care of HCV reduced the treatment lag by 71% compared to traditional care of referring HCV cases to specialized care (Gastroenterology or Hepatology) while keeping similar SVR. We intend to expand the program to improve quality of care for HCV patients in dialysis center. We propose active involvement of dialysis clinical staff including nephrologist, to increase HCV screening rate, promote timely diagnosis and treatment of CHC in patient with end-stage renal disease. This study is being conducted to evaluate real-world effectiveness of HCV DAA therapy in CHC hemodialysis patients when the DAA-treatment is managed and monitored by the clinical staff of hemodialysis center. Primary objective: To determine sustained virologic response (SVR) rates attained with open-label Zepatier administered through hemodialysis center under the supervision of a nephrologist in chronic hepatitis C infected (CHC) patient currently on hemodialysis. Secondary objective: 1. To estimate prevalence of HCV infection, severity of fibrosis (using non-invasive measures), and HCV detection rate in patients with End stage renal disease on hemodialysis. 2. To calculate the average treatment-lag time (time from HCV diagnosis to submission of treatment approval).
Open label multi center study for the donation of HCV positive kidneys to HCV negative recipients with interventional treatment to prevent HCV transmission upon transplantation.
Open-label, extension study to evaluate the safety and efficacy of combination therapy and its effect on sustained viral response biomarkers.
Renal impairment is common in patients with chronic hepatitis B infection. For those taking nucleotide analogues, renal toxicity of adefovir disoproxil (ADV) and tenofovir disoproxil fumarate (TDF) is a significant concern in chronic hepatitis B (CHB) patients. Early observational clinical data suggested that telbivudine (LdT) might have renoprotective effects. In this prospective study, consecutive CHB patients on combined lamivudine (LAM)+ADV/TDF are switched to LdT+ADV/TDF at recruitment and are followed up for 24 months. Estimated glomerular filtration rate (eGFR) is calculated with the Modification of Diet in Renal Disease (MDRD) equation. The effects of LdT on cell viability and expression of kidney injury or apoptotic biomarkers are investigated in cultured renal tubular epithelial cell line HK-2.
