Active clinical trials for "Liver Cirrhosis"

Patients with advanced chronic liver diseases treated at the Vienna General Hospital of the Medical University of Vienna will be offered to participate in this prospective observational trial. Clinical parameters and laboratory parameters will be recorded for all patients and patients will undergo a regular follow-up schedule with clinical visits at the Vienna General Hospital. This study is linked to a biobank with serum/plasma, ascitic fluid, urine, GI tract mucosal biopsies, liver biopsies and stool collected from the study participants.

The presence of varices is a serious complication of portal hypertension in liver disease. To prevent variceal haemorrhage, screening and surveillance aims to detect high-risk varices related to varices size and determine the need for primary prophylaxis. Varices size evaluated by endoscopists might not be perfect reference, influenced by experience and machine. Endoscopic ruler is a novel tool to measure the varices size under the endoscopy. The investigators aim to evaluate the bias of varices size between endoscopists and endoscopic ruler as the reference.

The goal of this observational study is to investigate the associations between a novel inflammatory marker, high sensitivity C-reactiveprotein to albumin ratio (hsCAR), and steatosis and fibrosis of metabolic dysfunction-associated fatty liver disease (MAFLD). The main question[s] it aims to answer are: [question 1] Can hsCAR serve as a clinical indicator to determine whether a patient has MAFD? [question 2] Can hsCAR determine whether MAFLD patients are complicated with liver fibrosis?

This observational study evaluates the concentration of immune protein S100A8/A9 in different liver failure syndromes, its interaction with the immune system and validity as an immunotherapeutic target to improve survival in patients with advanced cirrhosis and/or acute on chronic liver failure.

Patients with clinically significant portal hypertension allocated to implantation of a transjugular intrahepatic portosystemic shunt (TIPS) at the Department of Medicine II of the University Medical Center Freiburg, Germany will be offered to participate in this prospective observational trial. Clinical and laboratory as well as outcome parameters will be assessed before and within the first 12 months after TIPS implantation following a regular follow-up schedule with clinical visits at the University Medical Center Freiburg. During follow-up visits, serum/plasma samples and peripheral blood mononuclear cells (PBMC) are collected and stored in a associated biobank.

Patients with established liver cirrhosis, or end-stage liver disease (ESLD), are at high risk of developing liver cancer (hepatic carcinoma; HCC), portal hypertension, and sarcopenia, all which lead to significant morbidity and mortality. In this patient group the annual incidence of HCC is c. 2-8% and these patients are therefore included in ultrasound HCC screening programs every 6 months. In this study, the investigators are aiming to assess sarcopenia, clinically significant portal hypertension (CSPH), and HCC with a single short magnetic resonance (MR) examination. A neck-to-knee MRI-examination will be acquired to derive body composition profile (BCP) measurements including visceral and abdominal subcutaneous adipose tissue (VAT and ASAT), thigh fat free muscle volume (FFMV) and muscle fat infiltration (MFI), as well as liver fat (PDFF), spleen volume, and liver stiffness. Images will be further processed by AMRA Medical AB. AMRA's solution includes FFMV in the context of virtual control groups (VCG; using AMRA's vast database) and MFI. Furthermore, the spleen volume will be used to monitor the development of portal hypertension and explored together with other BCP variables in relation to hepatic decompensation events. HCC screening will be performed using so-called abbreviated MRI (AMRI), which consists of time series of contrast-enhanced T1-weighted images. The AMRI images will be read by an experienced radiologist. In the literature the sensitivity of AMRI to detect HCC is above 80%, with a specificity of c. 95%, compared to ultrasound sensitivity of 60%. In treating ESLD there is a desire of physicians to be able to predict future decompensation events in order to initiate treatment to prolong survival. Moreover, the ability to assess processes of sarcopenia in the patient would be highly valuable for clinical practice due its severe clinical impact. Finally, ultrasound-based HCC screening has poor diagnostic performance and a MR-based screening approach would significantly improve treatment outcome as more treatable and earlier HCC may be identified.

The aims of this study will be to identify the clinical characteristics, the management and the outcomes of acute kidney injury in patients with cirrhosis worldwide. Specific aims: To establish the severity of AKI across different regions To identify precipitants of AKI across different centers To identify the phenotypes of AKI across different centers To evaluate differences in the management of AKI across different centers and their impact on clinical outcomes To assess outcomes of acute kidney injury (resolution of AKI, in-hospital mortality, 28-day mortality, 90-day mortality)

This is an observational study exploring the performance of a novel point-of-care diagnostic testing platform designed to quantitate the presence of liver function biomarkers such as bilirubin. Blood samples will be collected from participants to further development and validation of the testing platform to support FDA review. The diagnostic device is intended to provide rapid in-office test results using a finger stick of blood, a reaction test device, and a smartphone app.

The LITMUS Imaging Study is a prospectively recruited, observational study of patients with histologically characterised non-alcoholic fatty liver disease (NAFLD). It aims to evaluate the diagnostic performance of imaging biomarkers (ultrasound elastography and magnetic resonance biomarkers) against NAFLD histological scores in a cross-sectional analysis and the natural history of NAFLD in a longitudinal study.

The investigators use machine learning capabilities on massive electronic health records for the purpose of developing a model that prioritizes individuals at high risk of progressing to liver cirrhosis, and validating it with participants that the model found to be at high risk. constructing and validating a reliable model, with sufficient accuracy to justify further and expensive means of detection, will enable treating patients with damaged liver at an early enough stage to allow improvement of the liver condition.
