Filter by:This is an open-label, pilot trial to test the safety and efficacy of transplantation of livers from Hepatitis C seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the liver transplant waitlist. Treatment and prophylaxis will be administered, using a transmission-triggered approach for the first scenario (HCV Ab+/NAT- donors, arm 1) and a prophylaxis approach for the later scenario (HCV Ab+/NAT+ donors, arm 2).
This is an open-label, pilot trial to test the safety and efficacy of transplantation of kidneys from hepatitis C seropositive non-viremic (HCV Ab+/NAT-) and HCV seropositive viremic (HCV Ab+/NAT+) donors to HCV seronegative recipients on the kidney transplant waitlist. Treatment and prophylaxis will be administered using a transmission-triggered approach for the first scenario (HCV Ab+/NAT- donors, arm 1) and a prophylaxis approach for the later scenario (HCV Ab+/NAT+ donors, arm 2).
The purpose of this study is to evaluate the efficacy and safety of GC1102 in combination of Nucleo(t)ide analogues (NAs) in patients with chronic hepatitis B
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 2000 chronic hepatitis B (CHB) patients with liver biopsy performed at least 1 year after antiviral therapy are enrolled. All the patients will receive original antiviral treatment for the following 10 years. Patients will be assessed at baseline and at every six months for blood count, liver function test, alpha fetoprotein (AFP), prothrombin time, liver ultrasonography, liver stiffness measurement (LSM), Hepatitis B virus (HBV) DNA and HBV serological markers. HBV-related endpoint events, including cirrhosis decompensations (ascites, esophageal variceal bleeding and hepatic encephalopathy), hepatocellular carcinoma (HCC), liver transplantation and liver-related death, will be collected during follow-up.
The study was conducted to observe the clinical features during pregnancy in women with chronic hepatitis B virus infection and mother-to-child transmission of hepatitis B virus.
This is a clinical study for GC1102 to demonstrate preventing the recurrence of hepatitis B virus (HBV) infection following liver transplantation and a dose-finding study to determine its optional dose.
The main purpose of the CoDISEN cohort study is to propose a model of prevention and care for HIV and viral hepatitis adapted to the needs of people who inject drugs (PWID) in Dakar, Senegal.
Patients who have completed 3 years follow-up of the past Beijing Science and Technology Commission Research will receive another 7-years anti-viral therapy. Patients will be assessed at baseline and every six months for blood cell count, liver function test, HBVDNA, AFP, prothrombin time, liver ultrasonography, and Fibroscan. CT or MRI and endoscopy will be performed at baseline and 7 years. At the end of the study, the cumulative rate of clinical hepatic hard endpoint will be calculated.
Most new hepatitis B virus (HBV) infections are acquired perinatally. In this study, pregnant women with HBsAg and HBeAg will receive tenofovir disoproxil fumarate during the last trimester of pregnancy and for two months following delivery. Their infants will receive hepatitis B (HB) immunization, starting with a first dose soon after birth. We hypothesize that the risk of mother-to-child transmission of HBV will be lower than 2%. The results of the study will help define policy to manage HBV infected pregnant women to prevent perinatal transmission.
