Active clinical trials for "Liver Cirrhosis"

This is a multi-center study to prospectively gather clinically-characterized plasma samples to determine the diagnostic performance characteristics (sensitivity and specificity) of the HCCBloodTest among patients with cirrhosis with and without HCC

Adult patients with chronic hepatitis B and cirrhosis of any etiology who are found to have suspected liver cancer are potentially eligible for the study. All enrolled patients will undergo two MRI scans using two different contrast agents. The type of contrast agent for the 1st MRI will be performed using hepatocyte-specific contrast agent. The participant will undergo the 2nd MRI using extracellular contrast agent. The MRI examinations will be independently interpreted by two different radiologists. The radiologists will evaluate focal hepatic lesions and categorize them according to the LI-RADS v2018 and EASL 2018. Once the diagnosis is made, the participants will be provided with the standard of care. After the initial treatment, the participants will be followed up with multi-phasic dynamic contrast-enhanced CT every 3 or 6 months for at least 2 years. Based on the prospectively written radiology reports, the diagnostic performances will be calculated and compared between MRI with hepatocyte-specific contrast agent and MRI with extracellular contrast agent, using the pathology and clinical criteria as the reference standard.

Background: The XL probe of FibroScan was recently developed to realize liver stiffness measurements (LSM) in overweight patients. Severe obese patients have a high prevalence of liver injuries and could benefit of liver evaluation prior to bariatric surgery. Objectives: Assess the FibroScan applicability, reliability and diagnostic performances in severe obese patients' candidates for bariatric surgery.

Exocrine pancreatic insufficiency (EPI) is the inability of the pancreas to perform a normal digestive function. The prevalence of IPE in patients with decompensated hepatic cirrhosis (HC) is unknown and most published series are short, old and use a single diagnostic technique with potential risk of false positives and negatives. Demonstrating IPE in a patient with HC can change their vital prognosis with the indication of pancreatic enzymes that can improve their nutritional status and help control their decompensations. Objectives: To assess the prevalence of IPE in patients with decompensated CH. To establish correlation between fecal elastase and 13C triolein breath test. Methodology: Unicentric, transversal study that will be carried out during hospitalization. Patients with HC who enter for decompensation and requiere hospitalization will be included consecutively. Exclusion criteria will include prior diagnosis of IPE, suspicion of biliary obstruction, more than 5 dep / d induced by laxatives or liquid stools. The diagnosis of IPE will be made with the combination of two techniques (13C triolein breath test and fecal elastase). Demographic, epidemiological data, clinical data as well as anthropometric parameters will be collected. A blood test will also be done to assess nutritional status and associated deficits. A multivariate analysis will be performed to assess the predictive factors of IPE

The existence of an adipose tissue microbiota causally involved in the triggering of a low grade inflammation could resemble what observed in liver fibrosis. To generate microbial hypotheses putatively responsible for the onset of liver fibrosis we sequenced the 16SrDNA gene from liver biopsies from 36 obese patients (ROLIVER cohort) and describe an original mathematical approach to decipher signatures of early stage of liver fibrosis F0, F1, F2.

Retrospective study of all patients diagnosed with primary biliary cholangitis during January 2001 to July 2016 at West China Hospital by review of medical records. The following variables will be retrospectively studied: age, sex, first symptoms, clinical characteristics, pathology, treatment, stage, complications of cirrhosis, other autoimmune diseases and long-term outcome.

Prospective multicenter cohort recruiting consecutive patients from 7 hospitals in Andalusia, southern Spain, according to following criteria: 1) HIV infection, 2) Chronic active HCV infection, 3) Older than 18 years, 4) New diagnosis of liver cirrhosis on the basis of a liver stiffness above 14 kiloPascals, 5) No previous or concomitant decompensation of liver disease. Patients are prospectively followed-up according to a uniform protocol of care. Epidemiological, clinical and laboratory variables are periodically recorded. The primary outcomes are the emergence of a liver decompensation (including hepatocellular carcinoma), liver transplant or death. The predictors of these outcomes are analyzed.

Cirrhotic patients are patients with high morbidity and mortality, it is very important for determining the prognosis of these patients. The importance increases when these patients waiting for a liver transplant. The Model for End-Stage Liver Disease (MELD) is a reliable measure of mortality risk in patients with end-stage liver disease. It is used as a disease severity index to help prioritize allocation of organs for transplant. MELD uses the patient values for serum bilirubin, serum creatinine, and the international normalized ratio for prothrombin time (INR) to predict survival. Blood tests that we use today in daily practice to evaluate the coagulation system (PT, PTT) do not check actually the functioning of the system, but examine the level of clotting factors and therefore only verify that the side of Anticoagulant of the equation and not the side of the procoagulant . To examine the coagulation system function tests have been developed, One of them is the thrombin generation. The purpose of the trial is to determine whether thrombin generation test can be a prognostic indicator in patients cirrhosis.

We hypothesize that individuals with Alpha-1 Antitrypsin (AAT) deficiency have ongoing liver injury which is not detected by the usual blood tests used to look at liver function. This ongoing liver injury leads to cirrhosis in a significant number of adults with AAT deficiency.

The purpose of this study is to evaluate the feasibility to stratify liver fibrosis in patients with chronic liver disease through non-invasive, spectral CT.
