Active clinical trials for "Hepatitis"

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.

This was a retrospective observational cohort study. The patients with chronic hepatitis B and cirrhosis who were treated with antiviral therapy in the Second Department of Liver Disease, Beijing Ditan Hospital, Capital Medical University from October 2008 to April 2020 were enrolled. Patients treated with antiviral drugs including interferon and/or nucleoside (acid) analogues lasting more than 6 months were included in the study. Interferon, nucleoside (acid) analogue monotherapy, combination therapy, sequential therapy, maintenance therapy and drug withdrawal therapy can all be included in the study. HBV DNA content, HBsAg/anti-HBs, HBeAg/anti-HBe, biochemical indexes, serum AFP and liver imaging (liver ultrasound) were collected before treatment (baseline), during treatment and after treatment. The virological response and clinical outcome after antiviral treatment for chronic hepatitis B were observed for at least 288 weeks, and the main evaluation indicators were the occurrence or reversal of cirrhosis complications, hepatocellular carcinoma and mortality. Secondary evaluation index: the influence factors of different clinical outcomes. To investigate the long-term virological response and clinical outcome of antiviral therapy in patients with chronic hepatitis B and liver cirrhosis and to clarify its influencing factors.

Granulomatous hepatitis are histopathologically defined by the presence of epithelioid and gigantocellular granulomas within the hepatic parenchyma. Hepatic granulomas are observed in 2 to 15% of liver biopsies. Causes of granulomatous hepatitis can be related to ethnic and environmental factors and in western countries granulomatous hepatitis are mostly related to sarcoidosis and autoimmune cholangitis. Infections (mycobacteria, coxiella burnetii, hepatitis C) and medications also provide granulomatous hepatitis. Sarcoidosis is a systemic disease of unknown etiology, which in third of cases has a chronic course. Five percent of patients die of their disease, mainly because of respiratory distress. Hepatic involvement is most often asymptomatic or pauci-symptomatic (moderate cholestasis and conglomerates of granulomas visible on imaging). More rarely, it can cause portal hypertension and its complications and be life-threatening. The aim of the Lyon Hepatitis Granulomatous (LHG) study is to better characterize granulomatous hepatitis and within these, severe hepatic sarcoidosis. This is a retrospective study conducted from January 2008 to December 2016 proposed to all patients with granulomatous hepatitis followed in the internal medicine and / or Hepato-gastroenterology departments (Croix-Rousse Hospital, Edouard-Herriot Hospital, Lyon Sud Hospital Center). This study will cover 596 patients who had a liver biopsy showing granulomas. The main objectives of the Lyon Hepatitis Granulomatous (LHG) study are to analyze i) the etiology of the disease and the contribution of molecular biology for infectious etiologies, ii) the contribution of nuclear imaging for sarcoidosis diagnosis versus conventional imaging, iii) treatment used and prognosis. This study will permit a better characterization of granulomatous hepatitis, and liver sarcoidosis in terms of prognosis as well as therapeutic management.

In South America, the prevalence of HBV is variable but high (> 8%) in the Amazon basin. In some areas, a third of HBsAg carriers are also infected with HDV, a major comorbidity factor. The pre-core mutations are associated with the negative HBe Ag phenotype which is associated with a more severe course. These mutations are of increasing and high frequency. French Guiana is populated by populations of African, European and Asian origins with chains of viral transmission which are not known and viruses probably of different origins with variable virulence and transmission potentials.

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.

ADDUP is an observational study of patients with alcoholic hepatitis. A structured interview is used to quantitatively estimate: Alcohol use Dietary intake Drug use (legal and illegal) in the weeks preceding onset of acute alcoholic hepatitis. After interview patients are followed up for 12 months with regard to response to therapy and survival. The study is intended to explore potential precipitants of alcoholic hepatitis.

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.

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

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.
