Active clinical trials for "Hepatitis"

This is a retrospective, non-interventional study. Investigators from infectious diseases and gastroenterology departments will participate this study. Patients data will be collected from hospital medical records.

Background: Chronic hepatitis D is a serious liver disease caused by a virus. Currently, no medications are approved to treat chronic hepatitis D. Objective: To test a combination of 3 drugs in people with chronic hepatitis D. Eligibility: People 18 years or older with chronic hepatitis D. Design: Participants will be in the study about 2 years. They will have 3 inpatient stays of 3 to 5 days. Participants will be screened. They will have a physical exam with blood tests. They will have a test of their heart function and an ultrasound: a wand that uses sound waves to create images of the liver will be rubbed over the skin on their torso. Participants will stay in the clinic for a 3-day baseline visit. They will have imaging scans, an eye exam, and a visit with a reproductive specialist. They will have a liver biopsy: about 1 inch of liver tissue will be removed, either with a tube inserted through a vein in the neck, or with a needle inserted through the participant s side. Participants will take the study drugs for 48 weeks. Two of them are tablets taken twice a day at home; 1 is a shot administered once a week. Participants will begin taking the drugs during a 5-day stay in the clinic. Then they will have 15 outpatient visits while taking the drugs and 7 more after they finish. The last 3-day clinic stay will be 6 months after participants finish taking the drugs. The liver biopsy, imaging scans, and other tests will be repeated.

This study aims to assess the efficacy and safety of bulevirtide (BLV) in chronic hepatitis D patients treated in Greek liver centers.

The main goal of this study is to collect post marketing data from patients with chronic hepatitis D virus (HDV) infection who are treated with bulevirtide to describe the long-term effects of bulevirtide treatment and evaluate the safety of participants treated with bulevirtide.

Background: The COVID-19 global pandemic killed more than 6 million people worldwide. Several vaccines have been developed against the virus that causes this disease. These vaccines are effective at preventing severe symptoms and death from COVID-19. Some people with chronic liver disease, especially those with an advanced condition called cirrhosis, do not respond to many vaccines as well as healthy people do. The goal of this natural history study is to find out how well people with chronic liver disease respond to the COVID-19 vaccines. Objective: To learn how chronic liver disease affects the body s immune response to vaccination against COVID-19. Eligibility: People aged 18 years or older with chronic liver disease. They must also be enrolled in protocol 91-DK-0214 or 18-DK-0091. Design: Participants will have 3 visits, each spaced 6 months apart. Each visit will last 2 hours. Participants will have their vital signs recorded. These include age, sex, race, height, and weight. They will give their medical history. At each visit, participants will have blood drawn through a needle inserted into a vein in the arm. The sample drawn at each visit will be from 1 to 8 tablespoons. At each visit, participants will fill out a questionnaire. They will answer questions about whether they have been vaccinated against COVID-19; whether they have had COVID-19; and whether they have been exposed to someone who had COVID-19. The questionnaire will take 10 to 15 minutes. Researchers will also look at results of past blood tests from other research studies.

CB06-036 is an investigational drug developed by Shanghai Zhimeng Biopharma Inc. for the treatment of Chronic Hepatitis B.

To acquire blood samples from subjects for various purposes, including: i) determining the sensitivity and specificity of select DNA methylation markers for the detection of various types of cancer, ii) identifying benign conditions that may induce false positive or false negative results, and iii) defining the effects of potential interfering substances, such as chemotherapy drugs.

Using peripheral blood mononuclear cells (PBMC) and serum collection from HBV and HCV infected patients in a number of different immunological assays, the investigators hope to identify any changes in the number and function of these immune cells and to investigate how these changes contribute to viral persistence and disease progression.

The purpose of the Antiretroviral Pregnancy Registry (Registry) is to detect any major teratogenic effect involving any of the Registry drugs when administered to pregnant women. Registration is voluntary and confidential with information obtained from the health care provider. A Registry-assigned identifier allows for follow-up capability. Information on subjects is provided to the Registry prospectively (prior to the outcome of pregnancy being known) through their health care provider, with follow-up obtained from the health care provider after the outcome is determined. Providers are strongly urged to enroll their patients as early in pregnancy as possible to maximize the validity of the data. In addition, the Registry is very interested in assembling a group of providers who are willing to make a commitment to report all of their site's antiretroviral pregnancy exposures to the Registry, thereby assuring all cases can be considered prospective. Providers are encouraged to contact the Registry for more information about this group. The Registry is informed in its analysis by other data, for example, retrospective reports and clinical studies. Given the increasing number of medications and more aggressive approach to therapy, more HIV- and hepatitis B-infected women may be treated during pregnancy or become pregnant while under treatment. The paucity of data on use and infant outcomes of antiretroviral therapies during pregnancy makes this Registry an essential component of the ongoing program of epidemiologic studies of the safety of these therapies. Each year the Registry has enrolled approximately 1300-1700 pregnant women in the US exposed to antiretroviral drugs. This number represents approximately 15% of the 8,700 HIV positive women who give birth to live infants annually in the US.

The goal of this observational study is to describe the clinical features and long-term prognosis in patients diagnosed with autoimmune hepatitis (AIH) in China and assess the effectiveness and safety of AIH treatment options in a real-world setting.
