Intestinal Microbiota Transplant in Alcohol-Associated Liver Disease

The purpose of this research study is to test the safety, tolerability, and effectiveness of the capsules that contain bacteria from healthy individuals when used to treat alcohol craving and drinking.

Inferior Vena Cava Pressure as Alternative to Hepatic Venous Pressure for EUS-guided Portal Pressure Gradient Measurement

This study investigates a new, simplified approach to measuring blood pressure within the liver (portal hypertension) using Endoscopic Ultrasound-Guided Portal Pressure Gradient Measurement (EUS-PPG). While this minimally invasive method traditionally relies on a hepatic vein as the baseline reference point, advanced liver scarring can make these veins twisted and highly difficult to access. To address this challenge, our study evaluates the Inferior Vena Cava (IVC)-the body's largest main vein-as an alternative reference site. Currently, it remains scientifically unproven whether the inferior vena cava or the hepatic vein provides the more reliable and accurate pressure reading for calculation, as anatomical distortion from cirrhosis can affect both areas differently. By measuring and comparing both venous compartments during a single, clinically scheduled endoscopy session, this study aims to determine if the pressures are truly interchangeable. Ultimately, this research will clarify which vessel serves as the optimal reference point, helping to establish a safer, more reliable diagnostic standard for patients with complex vascular anatomy.

Prevalence of Pain in Hospitalized Cirrhotic Patients

According to the WHO, pain is an "unpleasant sensory and emotional experience, linked to existing or potential tissue damage, or described in terms suggestive of such damage". It is a legal obligation to evaluate and take care of it (law of 03/04/2022). However, there are still areas where this is not addressed, particularly in cirrhotic patients (Piano V et al. 2023). The global prevalence of cirrhosis increased by 74.53% between 1990 and 2017 (Liu YB et al, 2022, INSERM France file and Zhai M et al. 2021). In France, the prevalence of cirrhosis is estimated to be 200,000 patients (Cohorte Constances 2017; Serfaty 2019). The causes are varied: toxic (alcohol), viral (hepatitis B, C, HIV), genetic (hemochromatosis, primary biliary cirrhosis) but also iatrogenic or linked to a metabolic syndrome, non-alcoholic fatty liver disease. The first symptoms of cirrhosis are fatigue, loss of appetite and weight, nausea and vomiting, discomfort and abdominal pain. More serious symptoms may appear such as depression, confusion, sleep disturbances, edema of the lower limbs, ascites, severe pruritus or jaundice. All of these symptoms can be the cause of the pain. However, to date, there are no studies in France on the epidemiology of pain in patients with cirrhosis (Piano V et al. 2023, Klinge M, et al, 2018). To evaluate the prevalence of pain in cirrhotic patients hospitalized at the Center Hospitalier de la Dracénie in Draguignan. Patients hospitalized at the Dracénie CH with a diagnosis of cirrhosis in its patients will be identified in the various departments by a referring doctor who will have to contact Dr PIANO. The latter, as investigating doctor, will then be able to select the patients meeting the inclusion criteria of the protocol and the informants of the existence of the research. He will explain the study to them in detail, give them sufficient time for reflection before obtaining their oral agreement and giving them the information-no-opposition letter. The research will require a single consultation lasting between 15 and 45 minutes. During the visit, the patient will be asked whether or not they are experiencing pain.

Study Evaluating the Efficacy and Safety of Belapectin for the Prevention of Esophageal Varices in NASH Cirrhosis

This seamless, adaptive, two-stage, Phase 2b/3, randomized, double-blind, multicenter, parallel-groups, placebo-controlled study will assess the efficacy, safety, and tolerability of belapectin compared with placebo in patients with nonalcoholic steatohepatitis (NASH) cirrhosis and clinical signs of portal hypertension but without esophageal varices at baseline.

Zanzalintinib in Second Line and Beyond for the Treatment of Advanced Liver Cancer

This phase Ib/II trial tests the safety, side effects, and best dose of zanzalintinib and how well it works in treating patients with hepatocellular (liver) cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Zanzalintinib is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of an abnormal protein that signals tumor cells to multiply, which may help keep tumor cells from growing. Giving zanzalintinib may be safe, tolerable, and/or effective in treating patients with advanced liver cancer.

Screening for Alcohol-related Cognitive Impairments in Cirrhotic Patients

80% of patients with alcohol use disorders (AUD) present cognitive impairments, such as memory and executive functions. These disorders may have repercussions in addiction treatment by altering the patient's adherence to care. The level of impairment is dependent on the onset of addiction, and also the duration of abstinence. A complete neuropsychological evaluation is necessary to highlight cognitive impairments. In practice, the evaluation of these disorders by practitioners, is done with the help of tools of screening like the MoCa (Montreal cognitive assesment) and the BEARNI (Brief evaluation of alcohol related neuropsychological impairment). However, none of these tools have been evaluated in patients with alcoholic cirrhosis. Indeed, some studies have suggested that liver disorders including cirrhosis may be a factor aggravating cognitive disorders. The purpose of this study is to evaluate the ability of the BEARNI tool to detect alcohol-related cognitive problems in patients with alcohol-related cirrhosis.

Evaluation of a Modified Bowel Preparation Regimen in Cirrhotic Patients Undergoing Colonoscopy

Inadequate bowel preparation compromises colonoscopy quality and diagnostic accuracy, and cirrhosis is a recognized independent predictor of poor bowel cleansing. However, no bowel preparation regimen has been prospectively validated or specifically tailored for cirrhotic patients. This multicenter, prospective, randomized, single-blind controlled clinical trial will evaluate whether the addition of adjunctive measures as an intensified bowel preparation protocol improves bowel cleansing quality in adult patients with cirrhosis undergoing elective outpatient colonoscopy. Participants will be randomized 1:1 to receive either a standard bowel preparation protocol, consisting of a 2-litre split-dose polyethylene glycol (PEG) regimen combined with a one-day low-residue diet and clear liquids the afternoon before the procedure (control), or the same split-dose regimen with the assigned adjunctive measures: 15 mg bisacodyl, a 3-day low-residue diet, and clear liquids the day before colonoscopy (intervention). The primary outcome is the proportion of patients achieving adequate bowel preparation, defined as a Boston Bowel Preparation Scale (BBPS) total score ≥6 with no individual segment score \<2. Secondary outcomes include polyp, adenoma, advanced adenoma and colorectal cancer detection rates, caecal intubation rate, patient compliance, tolerability, and adverse events. Pre-specified subgroup analyses will evaluate the influence of etiology and severity of cirrhosis and portal hypertension complications. By addressing a critical and unmet clinical need, this trial aims to generate high-quality evidence to optimize bowel preparation strategies in patients with cirrhosis, improve colonoscopy quality, and ultimately enhance colorectal cancer screening outcomes in this vulnerable population.

Preventing Liver Cancer Mortality Through Imaging With Ultrasound vs. MRI

The study is a randomized trial of two different screening methods for early detection of liver cancer in patients with cirrhosis of the liver. The goal of PREMIUM is to compare an abbreviated version of the diagnostic gold standard for HCC (aMRI) +AFP to the standard-of-care screening (US+AFP) in patients at high risk of developing HCC. The investigators hypothesize that HCC will be detected at earlier stages, allowing for more curative treatments and resulting in a reduction in HCC-related mortality.

Radiation Therapy in Treating Patients With Hepatocellular Carcinoma, Cholangiocarcinoma, or Liver Metastasis Who Have Impaired Liver Function

This phase I trial studies the side effects and the best dose of radiation therapy in treating patients with hepatocellular carcinoma, cholangiocarcinoma, or cancer that has spread from the original (primary) tumor to the liver who also have impaired liver function (liver damage caused by cirrhosis, chemotherapy, or surgery). Radiation therapy (RT) uses high energy x-rays to kill tumor cells and shrink tumors. New methods of giving RT to the liver may help control cancer.

Development of a Predictive Score for the Risk of Infection in the Immediate Post-liver-transplant Period

Liver transplantation (LT) is the only curative treatment option for patients with severe liver disease. Since 2007, the implementation of the MELD score in liver transplant allocation guidelines has led to a change in the profile of transplant recipients, notably with an increase in the proportion of patients receiving transplants for severe liver failure. Thus, in 2023, nearly 40% of liver transplant recipients whose primary indication for LT was cirrhosis had a MELD score greater than 35 (ABM Scientific Report 2023). These patients with severe pre-transplant liver failure often present with associated organ failure (Acute-on-Chronic Liver Failure, ACLF). Infections are the leading cause of death at 1 year post-transplant for patients transplanted with ACLF and are a major concern for all patients, representing one of the leading causes of death at 3 months post-transplant. Another common complication following LT is acute cellular rejection. Although frequent, this complication is reversible with treatment and results in graft loss in fewer than 5% of cases. The expression of the HLA-DR marker by monocytes (mHLA-DR) is correlated with immunoparesis and the risk of secondary infection and mortality in patients admitted to critical care. In a prospective, single-center pilot study of 99 liver transplant recipients, the Hepatology and Gastroenterology service at the Croix Rousse Hospital, Hospices Civils de Lyon, demonstrated that the kinetics of mHLA-DR levels measured immediately after transplantation could predict the risk of early significant infection (\< 1 month) after transplantation and 1-year post-transplant mortality. The early post-transplant kinetics of mHLA-DR expression recovery appeared to be a more relevant predictor of the risk of early post-transplant infection than a single-point-in-time value. The profile of immune recovery kinetics, as well as a pre-LT MELD score \> 30, were associated in multivariate analysis with the risk of developing an infection at 1 month post-LT and with 1-year post-LT survival. PREDITH study team hypothesize that the implementation of mHLA-DR testing immediately post-LT would enable the development of a predictive score for early post-LT infection combining clinical and biological risk factors for post-LT infection and immune monitoring.

Bumetanide vs. Furosemide in Cirrhosis

Patients with cirrhosis are frequently hospitalized due to an acute decompensation of their liver disease including bleeding, jaundice, encephalopathy, and volume overload. Volume overload is associated with increased mortality from acute hypoxic respiratory failure, hemorrhage from esophageal varices, and spontaneous bacterial peritonitis. Clinical practice guidelines describe sodium restriction and diuretics as first-line treatment, combined with regular body weight monitoring to assess response. In patients with suboptimal response to furosemide, alternative loop diuretics like torsemide or bumetanide may improve natriuresis. Bumetanide has a theoretic advantage over furosemide due to its more rapid and complete intestinal absorption, combined with a prolonged half-life in patients with hepatic dysfunction. In this pragmatic study, the aim is to compare the efficacy of diuresis with bumetanide versus furosemide among hospitalized patients with cirrhosis.

Decompensation of Cirrhosis and Iron Metabolism

Iron is a crucial metal whose metabolism is tightly regulated. Iron deficiency or iron overload are both deleterious at the cellular, organic and systemic levels. In line with the major role of the liver in iron homeostasis, links between iron metabolism and acute on chronic liver failure have been highlighted. Nevertheless, due to the difficulty of accurately assessing iron metabolism in this situation, therapeutic intervention on iron metabolism in this setting is currently not codified. A better understanding of these mechanisms is therefore essential, in particular by characterizing the impact of exposure to non-transferrin-bound iron in acute on chronic liver failure on short-term mortality. Overall, a better understanding of the physiopathological mechanisms of iron should allow to optimize the martial balance in this condition and also improve therapeutic approaches.

The Impact of Liver Cirrhosis on Outcomes in Trauma Patients

Given that there are only a few studies on the effects of cirrhosis on trauma patients and none have addressed the impact cirrhosis has on the incidence of infections, it is important that we study this to determine the mortality in cirrhotic trauma patients and ascertain the incidence of infectious complications in these patients. We hypothesize that trauma patients with cirrhosis will have higher rates of mortality and infectious complications.

mSEPT9 Biomarker for Predicting Hepatocellular Carcinoma Occurrence in Patients With Cirrhosis

This study aims to evaluate the role of the circulating epigenetic biomarker mSEPT9 in predicting the risk of hepatocellular carcinoma (HCC) in patients with cirrhosis. HCC is a primary liver cancer that frequently develops in individuals with cirrhosis, and early detection is critical for improving outcomes. This research involves 400 patients with cirrhosis who will be followed every six months for up to 60 months. During these visits, blood samples will be collected to analyze mSEPT9 levels. By identifying changes in this biomarker, the study seeks to improve early diagnosis and personalize surveillance strategies, potentially enhancing patient survival and quality of life.

Technology Enabled Strategies to Promote Treatment Adherence in Liver Transplant

Liver transplantation is increasingly performed for older adults with multiple comorbidities. Medication adherence is key to maintaining proper function of the transplanted liver and optimize health; however, adhering to post-transplant treatment is complex. This trial will study how available technology combined with transplant center resources and caregiver support can optimize medication adherence, quality of life, and health outcomes among new liver transplant recipients at 3 centers.

Liver Cirrhosis Network Rosuvastatin Efficacy and Safety for Cirrhosis in the United States

This is a double-blind, phase 2 study to evaluate safety and efficacy of rosuvastatin in comparison to placebo after 2 years in patients with compensated cirrhosis.

Simvastatin in Preventing Liver Cancer in Patients With Liver Cirrhosis

This phase II trial studies how well simvastatin works in preventing liver cancer in patients with liver cirrhosis. Simvastatin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

The Efficacy of Aerobic Exercise Training on ANS and Endothelial Function in Compensated Cirrhosis

The goal of this randomized controlled trial is to investigate whether a 16-week structured aerobic exercise program combined with nutritional consultation can improve autonomic and endothelial function in patients with compensated cirrhosis. Study Design: This assessor-blinded, parallel-group randomized controlled trial will be conducted at King Chulalongkorn Memorial Hospital, Bangkok, Thailand. Fifty adults with compensated (Child-Pugh class A) cirrhosis will be recruited during routine hepatology clinic visits. Eligible participants are aged 45-75 years, have a sedentary lifestyle (\<150 minutes of moderate or \<75 minutes of vigorous physical activity per week), and have abstained from alcohol for at least six months. Exclusion criteria include active or recently treated hepatocellular carcinoma (within three months), severe portal hypertension complications (untreated large varices, prior variceal bleeding, or severe gastropathy), transjugular intrahepatic portosystemic shunt (TIPS), unstable cardiac disease, orthopedic limitations, morbid obesity (BMI \>35 kg/m²), or current use of alpha- or beta-blockers that affect autonomic function. Intervention: Participants will be randomly assigned to either the intervention or control group. Both groups will receive nutritional consultation and individualized dietary guidance at baseline, week 8, and week 16. Nutritional goals are set at 35 kcal/kg/day and 1.2 g/kg/day of protein intake. If targets are unmet, the dietitian will provide individualized recommendations to support adequate intake. The intervention group will participate in a 16-week aerobic exercise program consisting of brisk walking at moderate intensity (50-70% of maximal heart rate), totaling 150 minutes per week. The program includes two phases: * Phase 1 (Weeks 1-4): Combined hospital-based (1 session per week) and home-based exercise under physical therapist supervision, with gradual intensity titration. * Phase 2 (Weeks 5-16): Fully home-based exercise following prescribed intensity and frequency, with weekly follow-up via telephone or messaging to monitor adherence, safety, and exercise log completion. The control group will maintain their usual physical activity levels while receiving the same schedule of nutritional consultations and weekly follow-up for monitoring compliance and adverse events. Outcomes: Primary outcomes include changes in autonomic and endothelial function after 16 weeks. * Autonomic function will be assessed using the Ewing autonomic battery test (HR response to standing, deep breathing, and Valsalva maneuver; BP response to posture and sustained handgrip) and heart rate variability (HRV) indices (SDNN, RMSSD, LF/HF ratio). * Endothelial function will be evaluated using flow-mediated dilation (FMD) of the brachial artery, analyzed via Cardiovascular Suite™ software to assess nitric oxide-dependent vasodilation. Secondary outcomes include: 1. Splanchnic hemodynamics: Changes in celiac and superior mesenteric artery (SMA) blood flow measured via mesenteric Doppler ultrasound (Vivid IQ, GE Healthcare). Time-averaged mean velocity (TAMV), vessel diameter, and blood flow will be recorded at baseline and post-intervention. 2. Sarcopenia-related measures: Muscle mass (DEXA, BIA), muscle strength (handgrip dynamometry), and physical performance (6-minute walk test). 3. Laboratory outcomes: Serum ammonia, liver function tests, fasting glucose, albumin, renal function, and coagulation profile. 4. Correlative analyses: Associations between (a) muscle mass and serum ammonia, and (b) muscle mass and autonomic parameters (e.g., HRV indices).

Effect of Laparoscopic Splenectomy on Renal Function in Cirrhotic Patients With Hypersplenism (2-Year Follow-Up)

Patients with liver cirrhosis often have impaired or at-risk kidney function due to the close link between liver and kidney (hepatorenal syndrome). Laparoscopic splenectomy is commonly used to treat splenomegaly and hypersplenism in these patients, but its impact on kidney function over 2 years is unclear. This study will follow patients undergoing laparoscopic splenectomy to measure changes in kidney function before and after surgery, identify risk factors for kidney damage and whether laparoscopic splenectomy can improve kidney function in the long term, and help improve care to protect kidney function in cirrhotic patients .

Timing of Endoscopic Intervention for Acute Variceal Hemorrhage: an RCT

Acute variceal upper gastrointestinal hemorrhage remains a hot potato in cirrhotic patients. The purpose of this study is to figure out whether urgent endoscopy (within 6h after gastroenterological consultation) is superior to non-urgent endoscopy (between 6h and 24h after gastroenterological consultation) in reducing rebleeding for these patients. This is a multi-centered, prospective, randomized, and controlled trial. 400 patients with suspected variceal bleeding will be randomized in a 1:1 ratio to receive endoscopic intervention either within 6h or 6-24h. Randomization is conducted by permuted block randomization stratified by age, systolic blood pressure (SBP), and pulse rate. The primary efficacy endpoint is rebleeding within 42 days after control of acute variceal hemorrhage. This trial will provide valuable insights into the efficacy between the urgent endoscopy group and the non-urgent endoscopy group.

Microplastics, Cirrhosis and Portal Hypertension

Cirrhosis and portal hypertension are associated with an hyperdynamic circulation and hepatic inflammation, leading to complications like ascites, variceal bleeding, acute kidney injury, and higher infection risk. Microplastics (MPs) are a global plastic pollution issue, and studies have found plastic MPs or nanoparticles (NPs) contaminating human, animal and environmental ecosystems.It has been noted that the accumulation of MPs increases with a reduction in size of the plastic particle. MPs are categorized into primary particles such as manufactured plastics including pellets and cosmetic microbeads and secondary particles which originate from mechanical and ultraviolet disruption of large plastic particles. MPs can be ingested via food or beverages, especially plastic packaged comestibles or inhaled as environmental pollutants. Contamination of medications such as antibiotics, intravenous fluids, albumin and medical devices is another source of exposure to microplastics in patients with chronic liver disease (CLD)In particular exposure to endoscopic interventions, liver biopsy, and invasive procedures such as paracentesis and interventional radiology procedures can lead to plastic exposure and deposition of MPs in the liver and other tissues in patients with cirrhosis. It may be hypothesized that these may contribute to hepatic inflammation and progression of cirrhosis and portal hypertension. Globally, there is new research on the influence of MPs on the environment, plant and animal ecosystems and human health. Polystyrene (PS) microspheres that concentrate in the liver, intestine and the kidneys of mammals disrupt lipid and energy metabolism, impair mucus secretion, and alter the microbiome. Therefore, studies are required to assess how and to what extent, MPs impact human health, and affect chronic diseases like cirrhosis and reduce longevity. The study investigators will assess the presence of MPs in the liver, kidneys and intestine of patients with liver cirrhosis and compare it with those without underlying liver disease and determine the impact on portal hypertension and fibrosis, and cardiovascular and metabolic function.

DICE Study- Diastolic Improvement With Carvedilol & Empagliflozin in Patients With Cirrhosis

1. This proposed double-blind placebo controlled randomized controlled trial incorporates recent advances in management of heart failure and portal hypertension using the SGLT-2 inhibitor i.e. EMPAGLIFLOZIN. The drug has been found to be useful in large trials on heart failure with preserved ejection fraction in the general population with improvement in MASLD progression, with improvement in body weight and hepatic steatosis but no change in liver fibrosis. 2. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been shown to reduce the development and progression of heart failure in patients with type 2 diabetes and in those with heart failure and a reduced and preserved ejection fraction. In patients with cirrhosis safety of empagliflozin in a dose of 10 mg has been demonstrated. 3. Prevention of decompensation related events in cirrhosis is the key endpoint of any liver-directed therapy as the median survival in the compensated state exceeds 10 years but median survival in the decompensated state approximates 1.5 years. Previous data has demonstrated the risk of hepatic decompensation acute kidney injury and poor survival in patients with cirrhosis and heart failure with preserved ejection fraction (HFpEF) i.e. LVDD a large subset of whom meet criteria for CCM.

Rifaximin vs Placebo for the Prevention of Encephalopathy in Patients Treated by TIPS

TIPS has been used for 20 years, as a means of reducing portal pressure in patients with cirrhosis and portal hypertension related complications. TIPS proved more effective than alternative treatments in controlling or preventing variceal bleeding and refractory ascites. The main drawback of the TIPS procedure is progressive overt hepatic encephalopathy (OHE). Three risk factors for post-TIPS OHE have been identified: age over 65 years, history of previous episodes of OHE, and Child-Pugh score equal to or over 10. However, the incidence of post-TIPS OHE in patients fulfilling these criteria remains close to 35 %.

Durvalumab (MEDI4736) and Tremelimumab for Hepatocellular Carcinoma in Patients Listed for a Liver Transplant

Immunotherapy can safely downstage patients and achieve durable systemic disease control to improve clinical outcomes in HCC patients undergoing liver transplant.
