Active clinical trials for "Hepatitis C"

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.

A 5-year study to observe and describe long-term patient management and treatment patterns with associated outcomes of patients who previously enrolled in Protocol AI452009 (i.e., the CCgenos cross sectional phase, ClinicalTrials.gov Identifier: NCT01293279) and had their genotype characterized at diagnosis of HCV infection in a real world clinical practice in 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.

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.

Direct acting antivirals offer a new opportunity to monitor the immune response in Hepatitis C infection. In this study cytokine markers will be measured during therapy up to time point SVR 12 an correlated to clinical Parameters and regular laboratory findings.

BACKGROUND It is estimated that around 71 milion people live with chronic hepatitis C virus (HCV) infection. This may lead to the development of liver cirrhosis and hepatocellular carcinoma (HCC). Liver cirrhosis is considered as one of the most common risk factors of hepatocellular carcinoma (HCC). HCC is seventh most common cancer worldwide. The treatment of HCV with direct-acting antivirals (DAAs) has led to the increase of sustained virological response (SVR) rates to more than 90%. It is suggested that the virus eradication reduces, but not eliminates the risk of HCC. This concerns especially patients with liver cirrhosis or previous HCC history. There are reports of early occurrence of HCC after the DAA treatment. Therefore, patients undergoing successful HCV treatment should be monitored for the possibility of hepatoccelular carcinoma occurrence. AIM OF THE STUDY In this study the investigators aimed to assess the occurrence of HCC after direct acting antiviral HCV treatment and evaluate whether the course of HCC and liver function differ among the population of patients treated with DAAs and those who were not receiving the therapy with DAA. MATERIAL AND METHODS This is the observative, cohort, retrospective study which will be performed in several clinical centres in Poland. The inclusion criteria are: hepatocellular carcinoma diagnosis, age >18 years old. The investigators will collect both epidemiological (age, gender, comorbidities, alcohol abuse) and clinical data (serum bilirubin, alanine, aspartate aminotransferase, platelets, gammaglutamyltransferase, alkaline phosphatase and alpha-fetoprotein level, Child-Pugh and MELD score, imaging tests, liver biopsy and elastography, if performed). In all patients, the HCV infection and co-infections will be assessed. In those who underwent the DAA treatment, the composition of the therapy and response to the treatment will be evaluated. Statistical analysis will be performed in subgroups of patients undergoing DAA treatment and without the therapy. The distribution of continuous variables will be analysed by the Shapiro-Wilk test. Quantitative data will be analysed using the Mann-Whitney U test or Kruskal-Wallis ANOVA when appropriate. Qualitative data will be compared using the χ² test or the Fisher exact test. Correlations between quantitative variables will be assessed using the Spearman correlation coefficient. P value will be set at <0.05.

Prospective study to calculated the incidence of hepatocellular carcinoma in hepatitis C virus infected patients after stem cell therapy.

Retrospective prospective cohort study aimed at Assessing the predictors to the response to the antiviral combined therapy with pegylated Interferon (Both types: Alfa 2 A and Alfa 2 B) in hepatitis C virus infected Egyptian patients.

Vertical HCV Transmission has been extensively studied, with a risk around 5% (range: 3 to 10%). Spontaneous viral clearance in infected children during childhood can occur, but data about this phenomenon are scarse, justifying the study.

According to the centres taking part in the ALHICE survey, the number of HIV-HCV co-infected women is currently decreasing. This drop was first noted in 2006 and persisted in 2007. What might have been considered a chance phenomenon during the first year (2006) was confirmed in the beginning of 2008. In view of this information, the investigators wished to ascertain the reality of this trend and to investigate its causes, by attempting to answer the following questions: - Has the prevalence of risk factors for HCV infection changed among the general population over the past 10 years? Has the prevalence of risk factors for HCV infection changed among HIV/HCV co-infected women over the past 10 years? Is the change in the number of co-infected women who gave birth during the past 10 years related to the prevalence of certain risk factors among this population? Is the change in the number of co-infected women who gave birth during the past 10 years related to a decrease in certain risk factors for HCV infection among the general population? Have changes in addictive behaviour among women of child-bearing age played a role in the decreasing number of HCV-contaminated children? Furthermore, follow-up data from HCV-infected children born during this period will provide information concerning the course of HCV infection. The objectives are to study trends in numbers of deliveries among HCV/HIV co-infected women as well as trends in risk factors for HCV infection among women of child bearing age and lastly to create a cohort of HCV infected children.
