The Use of MRI Apparent Diffusion Coefficient Value (ADC Value) to Assess Liver Cirrhosis
Hepatitis CHepatitis is known to induce severe liver diseases. The evaluation of the severity of liver cirrhosis is very important for the selection of appropriate treatment plan and the monitoring of patient response to treatment, accurate staging of liver fibrosis is critical because it determines the indication of antiviral treatment and prognosis of patients with chronic viral hepatitis, DWI is a particularly appealing method for the diagnosis of liver fibrosis because it is easy to implement and process, without the need for contrast agents. Apparent diffusion coefficient (ADC) has been shown to be a promising marker of fibrosis and cirrhosis.
Patients With Chronic Hepatitis B and Low Viremia Not Receiving Antiviral Therapy
Hepatitis BChronicThis observational long-term follow-up study will evaluate demographic, clinical, histological, biochemical, and virological parameters of patients with chronic hepatitis B and low viremia who do not require antiviral therapy according to current guidelines. Liver stiffness values as detected by FibroScan and ARFI will also be collected if available. All data will be collected at yearly intervals (minimum). Patients included in the study are followed for up to 10 years. The target sample size is <1000.
Study of the Role of Dendritic Cells in the Recurrence of Hepatitis C After Liver Transplantation....
HCV InfectionRe-infection of the liver graft occurs universally following liver transplantation for HCV-induced end stage liver disease. Interestingly, the manifestation of HCV infection ranging from an asymptomatic carrier state to rapid progression to liver cirrhosis is extremely variable from one patient to another. The host and viral factors being responsible for the different course of HCV infection are poorly understood. Our study will focus on dendritic cells which are known to play a critical role in the control of viral infection. Viral factors (quasispecies evolution) will also be analysed and Th1 Th2 cytokines produced in the serum evaluated.Thirty liver transplanted patients will be included : 20 patients transplanted for HCV-related disease and 10 controls transplanted for non HCV-related disease. Blood samples will be taken just before transplantation and at different time -points up to 5 years after transplantation. Function of blood monocyte-derived DC will be evaluated. Circulating blood plasmacytoid (pDC) and myeloid DC (mDC) sub-populations will be enumerated. HCV quasispecies evolution will be analysed. This study may help to define prognostic markers on progression of hepatitis C in liver transplantation and allow the development of new immunotherapeutic drugs
Observational Study on Pregnant Women With Chronic Hepatitis B and Their Infants
Hepatitis BChronicThe 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.
Tenofovir Combination or Mono-therapy for MDR CHB
Chronic Hepatitis b With Multidrug ResistanceTreatment of multidrug resistant (MDR) chronic hepatitis B (CHB) is still a challenging issue. Hence, the investigators will perform a multicenter prospective cohort study for the evaluation of tenofovir disoproxil fumarate (TDF)-based therapy for MDR CHB at real life settings.
Hepatitis E Infection : Emergence Mechanisms in North-Eastern France of Polymorphic Clinical Forms....
Hepatitis E Infection in Humans and in EnvironmentThe present research aims to collect virological and clinical data on hepatitis E virus (HEV) infections, either in acute or chronic forms of HEV infection in North-Eastern France, with liver- or non liver-related symptoms, plus data on HEV circulation in the outside environment. The purpose of this study is to improve the diagnosis and care of HEV-infected patients, as well as the preventive features to take into account in order to avoid food- and environment-borne infections. At last, we will investigate HEV molecular characteristics, with the hypothesis that some advantageous HEV strains coul be more pathogenic for some tissues and/or organs.
Alcoholic Hepatitis in Latin-America: A Prospective and Multicentric Study (AH-LATIN).
HepatitisAlcoholicThe primary objective of this study is to determine the prevalence of AH in addition to its clinical characteristics and in-hospital mortality of patients that are hospitalized for AH in different hospitals across Latin American countries This study is carried out in different health centers throughout America, with all the countries belonging to the Latin American Association for the study of liver diseases (ALEH) more Canada and United States This would allow us to better understand the epidemiology of AH in our region and thus implement prevention measures with more solid data. Importantly, this would allow us to optimize therapeutic measures
Cross Sectional Survey on the Burden, Impacts and Causes of Hepatitis C Virus (HCV) Outbreak in...
Hepatitis C Virus InfectionPast or Present1 moreThis study investigates hepatitis C virus (HCV) outbreak in South West general population in Burkina Faso with three specific objectives: estimate HCV prevalence in South West Region general population in 2019; identify factors associated with recent HCV infection (in subjects younger than 20 years); and evaluate the pilot treatment strategy implemented by the national program for diagnosed cases during investigation.
VIRal Hepatitis and GAllstone Disease Study
Gallstone AttackViral HepatitisThe study aims to investigate possible associations between ongoing viral hepatitis (i.e. hepatitis A, B, C or E virus infection) and ultrasound or computed tomography-verified gallstone disease.
Chronic Hepatitis B and C Recall Northern Holland
Hepatitis BHepatitis CThe project aims to retrieve patients diagnosed with chronic hepatitis B (cHB) and hepatitis C (cHC) who are lost to follow-up.Data files of the Public Health System and microbiology laboratories will be explored for registered cases of cHB and cHC. Subsequently the investigators will compare the registered cases with the list of known cHB and cHC patients in hospital care. Patients lost to follow up will be informed and approached via either the Public Health Service (PHS) or their primary care physician. Identified patients will be invited for re-evaluation at the regional hepatitis centre (The North Western Hospital, formerly Medical Centre Alkmaar) to assess the current status of their chronic disease. Evaluation will be performed in accordance with (inter-)national guidelines, no extra interventions will be performed. After completion of re-evaluation, a final report will be made and send to both patient and primary care physician with recommendations for further follow-up.
