Active clinical trials for "Hepatitis"

This study is a two-way, non-interventional long-term dynamic follow-up clinical observational cohort study. In the Second Division of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, chronic hepatitis C patients who were treated with interferon combined with ribavirin (PR) antiviral therapy (PR treatment for 6 months or more) and / or direct acting antivirals (DAAs ), and the baseline, antiviral treatment and discontinuation follow-up data of patients before antiviral treatment were collected, and follow-up observations of patients were carried out for every 3-6 months. The clinical data such as clinical biochemistry, HCV RNA and serological indicators (anti-HCV), AFP, and liver imaging (liver ultrasound) were collected during the study period. The virological response and clinical outcomes of chronic hepatitis C antiviral therapy were observed for at least 144 weeks. The incidence of liver cancer and decompensated liver cirrhosis after discontinuation of the drug was the main evaluation index. The aim is to explore long-term virological response and clinical outcomes, and elucidate its influencing factors.

This study was a clinical observational cohort study of two-way, non-intervention long-term dynamic follow-up. Enrolled in the Department of Liver Diseases, Beijing Ditan Hospital, Capital Medical University, with interferon combined with ribavirin (PR) antiviral therapy (PR treatment greater than or equal to 6 months) and/or direct acting antivirals (DAAs) In patients with chronic hepatitis C, the baseline, antiviral treatment and withdrawal follow-up data before the antiviral treatment were collected, and the patients were followed up for 3-6 months. Clinical data such as clinical biochemistry, HCV RNA and serological markers (anti-HCV), AFP and liver imaging (liver ultrasound) were collected during the study period. At least 144 weeks of observation on the virological response and clinical outcome of anti-viral treatment of chronic hepatitis C, the main evaluation index of liver cancer and decompensated liver cirrhosis after stopping the drug, and exploring the antiviral treatment of patients Long-term virological response and clinical outcomes, clarifying their influencing factors.

Hepatitis c associated glomerulonephritis is an immune complex disease that occurs in 21% of patients who have HCV infection.

Children with clinically diagnosed leukemia may experience occult HBV infection after chemotherapy immunosuppressive therapy, which may affect the normal course of leukemia treatment. However, this is not caused by clinically relevant diagnosis and treatment measures but exists in vivo.

In this project proposal, the investigators will investigate the genetic alterations of Hepatitis B Virus (HBV) strains circulating in Belgian patients who developed end stage liver disease. Additionally, the investigators will compare and link these data sets with three genetic factors involved in immune system response.

An prospective / retrospective multicenter observational study whose objectives are to understand the interactions between hepatitis c virus and Non Hodgkin lymphomas. The characteristics , evolution and treatment of diseases will be observed from the study.

More recent studies have shown that the HBV-infected population has a greater risk of development of hepatocellular carcinoma. Nevertheless, there are still a significant number of people chronically infected by HBV who do not develop the complication. Hence, there exist biological markers that could be indicator for the disease-inducing and carcinogenic potential of the virus.

According to the guidelines for treating hepatitis C livers stiffness (LS) measurement is equivalent to liver biopsy to prove grade-2 fibrosis or more by Metavir-score. Also flares of inflammation in other viral hepatitis (B) have been reported to increase the elastography measurements. There are very few reports so far on longitudinal data in a treatment cohort. In this study investigators will follow patients who undergo active treatment for hepatitis C virus (HCV). Investigators will collect longitudinal data of liver elastography and compare this to the current status of liver inflammation by blood samples. This may be important in order to know if transcutaneous US with elastography can be used as a tool to monitor active inflammation in liver disease and to quantify how much the inflammatory component contribute to LS and finally if it is possible to reverse not only inflammation but also liver fibrosis by treating viral hepatitis. Our aim is to assess shear wave elastography (SWE) and investigate if the method can be used, not only to define the indication for treatment through LS measurements, but also if LS due to inflammation and fibrosis may be reversible in treated patients. To investigate what role frequency of measurement obtains in follow up of patients with HCV play.

to investigate the prevalence of hepatopulmonary syndrome in cirrhosis patients caused by Hepatitis B in western China

The XN-20, is a full blood count (FBC) analyser with an extended differential counting and flagging System. The XN-Series' individual channels allow real-time reflex analysis, and uses a two stage process to classify the white blood count (WBC) sub-populations and detect the presence of abnormal reactive and malignant cells. In regards to lymphocytes in the peripheral blood, the machine has the capacity to distinguish activated from non-activated T-cell subsets using a very small volume of EDTA sample (88uL) (including remnant sample from a standard full blood count) with results available in 1.5 minutes. It is a fully automated process and can be considered as an alternative rapid flow cytometry method. Objective of the SASA study: to investigate the signal pattern of white blood cells assessed using the XN-20 full blood count platform in patients with untreated viral infections i.e. HIV, HCV and HBV. The data from the analysis will be reviewed in conjunction with patient's demographic and clinical disease characteristics with the aim of detecting characteristic cell populations that can be used in the development of system flags for future studies.
