The Influence of Nutritional Factors on the Prognosis of Liver Cirrhosis Patients and the Exploration of Predictive Models

Start date: November 1, 2023
Phase:
Study type: Observational [Patient Registry]

Cirrhosis is a progressive developing liver disease transforming normal hepatocytes into scar tissue with loss of function.The prevalence of cirrhosis has approximately tripled over the past two decades. With the increasing incidence of chronic liver disease, about 2 million people died from cirrhosis worldwide. Currently, D'Amico stage classification and Child-Pugh and Model for End-Stage Liver Disease (MELD) scores constitute the best tools to predict mortality in patients with Cirrhosis; however, one of their main limitations is the lack of evaluation of the nutritional and functional status. Patients with End-Stage Liver Disease (ESLD) have reduced nutritional intake, hypermetabolism, increased energy expenditure, impaired fasting adaptability, decreased hepatic glycogen reserves, and increased consumption of protein as the main energy donor that often lead to malnutrition, therefore, malnutrition is one of the most common complications in patients with Cirrhosis, is closely related to the increase in morbidity and mortality. Moreover, malnutrition is closely related to the high incidence of infection, ascites, hepatic encephalopathy, and hepatorenal syndrome, and is an independent risk factor affecting the survival rate of patients with End-Stage Liver Disease, including liver transplantation. Therefore, malnutrition should be treated as equally important complications such as ascites and hepatic encephalopathy, and accurate screening, evaluation and appropriate nutritional intervention measures should be taken to improve the prognosis of patients with Cirrhosis. This study aims to establish a nomogram model about nutritional factors to predict the prognosis of patients with Cirrhosis, verify and optimize the model, through the establishment of the model, to more comprehensively evaluate and predict the prognosis of patients with Cirrhosis from the perspective of nutrition, to provide sufficient basis and lay a solid foundation for further nutritional intervention and improve patient prognosis.

Evaluation of Cirrhotic Cardiomyopathy by Cardiac MRI in Patients Waiting for Liver Transplant.

CARDIOFIBROCIR
Start date: March 31, 2024
Phase:
Study type: Observational

The aim of this multicenter prospective observational pilot study is to describe the evolution of myocardial fibrosis in cirrhotic patients before and after liver transplantation (LT). Through multimodal analysis of myocardial function and architecture, and analysis of specific markers of inflammation, we aim to explore the following hypotheses: 1) systemic inflammation promotes myocardial fibrosis in cirrhotic patients and could be an early marker of cirrhotic cardiomyopathy; 2) LT allows resolution of myocardial fibrosis by preventing the bacterial translocation that favors the development of deleterious systemic inflammation.

Noninvasive Prediction of Portal Hypertension in Cirrhosis Using Sound Touch Viscoelastography

Start date: March 15, 2024
Phase:
Study type: Observational

The objective of this observational study is to investigate and validate the utility of the Sound Touch Viscoelastography(STVi) technique in patients with liver cirrhosis for noninvasive prediction of Portal hypertension (PH). The primary research questions it seeks to address are as follows: - What is the correlation between the liver STVi index and Portal Venous Pressure Gradient (HVPG)? - Is STVi an available tool to non-invasively predict PH in patients with liver cirrhosis? And the effectiveness and practicality of STVi will be validated. - To establish a predictive model for Clinically Significant Portal Hypertension (CSPH) utilizing liver STVi index as the primary indicator. The HVPG is considered as the gold standard in our study and STVi was employed to quantify the STVi index of the liver in patients with liver cirrhosis. Researchers will compare the two patients groups, HVPG≥10 mmHg and HVPG<10 mmHg, to see the usage of STVi in the noninvasive prediction of PH.

Intra-Hepatic Microbiota in Alcoholic Hepatitis

HepMAH
Start date: June 2024
Phase:
Study type: Observational

Alcoholic hepatitis (AH) is a serious complication of alcoholic liver disease (ALD). The histological presentation of AH is characterized by neutrophilic lobular inflammation, macrovesicular steatosis, hepatocyte ballooning and necrosis and the presence of Mallory bodies. In cases of severe HA, defined by a modified Maddrey score of 32 or above, mortality at 1 month is estimated at between 10 and 50%. The only treatment to reduce early mortality is corticosteroid therapy. However, only 60% of patients respond to corticosteroids, and no benefit has been demonstrated on late mortality. Identifying new therapeutic targets is therefore a major challenge in this disease. Numerous pre-clinical studies and human data suggest the involvement of the intestinal microbiota in the pathogenesis of AH. Translocation of viable bacteria and microbial products from the digestive tract to the liver contributes to local and systemic inflammation, hepatocyte death and fibrogenesis. However, the intrahepatic microbial environment has never been characterized in HA. The study hypothesis is that the intrahepatic microbiota is modulated by bacterial translocation and is associated with clinical outcomes. The aim of this study is to determine the composition of the intrahepatic (obtained from transjugular liver biopsy), blood and fecal microbiota in patients with suspected severe AH from a monocentric prospective cohort in the Hepatology Department at Croix-Rousse Hospital (Lyon). Fifty consecutive patients with clinical suspicion of AH and indication for transjugular liver biopsy will be included. About thirty-five patients are expected in the confirmed AH group, and 15 in the group "alcoholic liver disease with no AH", based on data from the literature. The composition of the various microbiota will be determined by sequencing the 16S rRNA gene, and the results will be correlated with clinical data (corticosteroid sensitivity, overall survival, transplant-free survival, MELD score in particular) and histological data. This exploratory study will enable to analyze the intra-hepatic microbiota, and to study its link with intra-hepatic inflammation and the clinical course of patients with AH. The data generated by HepMAH will thus help identify potential new therapeutic targets linked to the gut microbiota, and provide a scientific basis for the development of therapeutic interventions targeting the microbiota in HA.

The Efficacy of Aerobic Exercise Training on Autonomic Nervous System and Endothelial Function in Patients With Compensated Cirrhosis

Start date: March 5, 2024
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to explore the impact of a 16-week aerobic exercise regimen on the autonomic nervous system and endothelial function in patients with compensated cirrhosis who maintain sedentary lifestyles. The primary research question is: 1) What effect does 16 weeks of aerobic exercise have on changes in the autonomic nervous system and endothelial function in cirrhotic patients? Additionally, the secondary research questions are: 1. How does a 16-week aerobic exercise program influence changes in muscle mass, muscle strength, and physical performance in cirrhotic patients? 2. Is there a correlation between muscle mass and parameters of the autonomic nervous system in cirrhotic patients? Participants in the intervention group will undergo 150 minutes of moderate aerobic exercise per week for 16 weeks, accompanied by a personalized nutritional plan (1.2 grams of protein per kilogram of ideal body weight per day and a calorie intake of 35 kilocalories per kilogram of ideal body weight per day). The control group will solely receive nutritional guidance and maintain their sedentary lifestyle. The researchers will compare outcomes between these two groups.

Efficacy and Durability of Hepatitis A Vaccination in Patients With Advanced Fibrosis and Cirrhosis

Start date: February 29, 2024
Phase: Phase 4
Study type: Interventional

The hepatitis A virus (HAV) is a significant global public health concern. The hepatitis A virus is transmitted primarily by the faecal-oral route, leading to acute hepatitis. Symptoms include low-grade fever, anorexia, jaundice, and typically resolve without complications. However, HAV infection in patients with chronic liver disease, especially those over 50 years old, may result in more severe outcomes, including fulminant hepatitis, with a higher mortality rate compared to the general population HAV vaccination is a cornerstone of prevention, especially in high-risk groups. Currently, there is a recommendation to vaccinate patients with chronic liver disease against HAV infection. However, these patients often have compromised immune responses, leading to lower vaccine efficacy compared to the general population. The goal of this randomized controlled trial is to compare the efficacy and safety of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen with an intensive 3-dose (0, 1, 6 months) schedule in patients with advanced fibrosis and cirrhosis. The main questions it aims to answer are: - Compared the seroconversion rate of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis. - Compared the antibody levels against the hepatitis A virus (Anti-HAV IgG) of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis.

Metobolomics in the Characterisation of HE

METABO-EH
Start date: March 1, 2024
Phase:
Study type: Observational

Hepatic encephalopathy is (HE) defined by the neurological and/or neuropsychological symptoms caused by an acute or chronic liver disease and/or a portosystemic shunt. Its pathophysiology is still debated, although the synergic role of hyperammonemia and inflammation is now admitted for years. Several additional mechanisms have been suspected, one of them being an altered permeability of the brain blood barrier (BBB). Nevertheless, many aspects remain poorly understood. The rise of "-omics" techniques, and especially metabolomics, allowed to identify more precisely the different metabolic pathways that are involved in the pathophysiology of HE. Using a high flow chemistry technique and multivariate data analysis, metabolomics is an accurate way to understand the pathophysiology and pathogenesis of multifactorial diseases such as HE. Several studies have been published in cirrhosis. It has been suggested that serum metabolites at admission, as well as thyroxine, can predict advanced HE in patients without brain failure. In a cohort including more than 600 patients, a higher microbially-derived metabolites, together with a lower thyroxine level, were associated with further development of brain failure. In another study from the same team, serum and urinary metabolites were significantly different in hospitalised patients who had developed poor outcome or not. Another study conducted in the CANONIC cohort as also found changes in metabolites of patients with cirrhosis and acute-on-chronic liver failure (ACLF), revealing mitochondrial dysfunction in peripheral organs that may contribute to organ failures. Last, our team previously analysed plasma and cerebrospinal fluid (CSF) samples of patients with cirrhosis and HE hospitalised in intensive care unit (ICU), showing alteration in ammonia and amino-acids metabolism, and also in energy metabolism. However, in the latest study, ALCF grading was not available. As many of these patients were in a severe condition, one could hypothesize that the metabolomic changes observed in these patients may have been confounded by an ACLF profile. Therefore, the objective of this study is to characterize the metabolomic fingerprints of HE in patients with cirrhosis, using 4 different groups of patients: patients with or without HE, with or without ALCF.

Endoscopic Ultrasound-Guided Portosystemic Pressure Gradient Measurements

EUSPREM
Start date: January 10, 2023
Phase: N/A
Study type: Interventional

Portal hypertension (PHT) is the main consequence of advanced chronic liver diseases (ACLD) and is often associated with severe complications leading to increased morbidity and mortality. Currently, the gold standard for the evaluation of the severity of PHT is the hepatic venous-pressure gradient (HVPG). The disadvantage of using the HVPG, besides the availability of the technique only in referral centres, is in the case of patients with vascular liver disorders because the HVPG underestimates the severity of PHT. Recent studies have evaluated the feasibility of the pressure gradient measurement through endoscopic transgastric and transhepatic access using special kit with a 25-gauge FNA needle (Cook Medical, Winston-Salem, NC, USA) and a compact manometer (Cook Medical, Bloomington, Ind, USA) that has the disadvantage of high purchase cost, no tracing of pressure possible and has not yet been properly correlated with the gold standard HVPG measurement or PPG measurement thus limiting its use in current practice. The aim of the study is 1. to assess and compare the correlations in the porto-systemic gradient measurement between a) direct portal vein puncture during TIPS insertion, b) direct portal and hepatic pressure measurements using a 22 Gauge FNA needle during endoscopic ultrasound procedure and c) indirect portal vein pressure measurements using the interventional radiology based hepatic HVPG procedure in patients with cirrhosis submitted to TIPS procedure for complications of portal hypertension and 2. To evaluate and compare the porto-systemic gradient obtained by direct portal and hepatic pressure measurements using a 22 Gauge FNA needle during endoscopic ultrasound and indirect measurement through HVPG measuring in patients with presinusoidal hypertension and those with portal vein thrombosis.

3D-MRE and 2D-MRE for Assessing Cirrhosis and Portal Hypertension

Start date: August 16, 2022
Phase:
Study type: Observational

How to construct a novel, non-invasive, accurate, and convenient method to achieve prediction of hepatic venous pressure gradient (HVPG) is an important general problem in the management of portal hypertension in cirrhosis. We plan to compare the ability of three demensional-magnetic resonance elastography (3D-MRE) to two demensional-magnetic resonance elastography (2D-MRE) to establish a risk stratification system and perform tailored management for portal hypertension in cirrhosis.
