Liver Diseases

Researchers are interested in determining whether it is safe to reduce anti-rejection medication by approximately 50% after liver transplantation and whether special blood tests called biomarkers can identify early signs that the body is starting to attack the new liver before it gets hurt.

The overall aim of this study is nephroprotection based on a calcineurin inhibitor (CNI)-free therapy beyond year one after orthotopic liver transplantation (OLT) in highly pre-selected patients with low rejection risk.

This is an open-label, non-randomized trial that will be conducted at three clinical sites, Thomas Jefferson University (TJU), the Hospital of the University of Pennsylvania (HUP) and University of Bern (UB). Enrollment will be allocated into one of 4 different cohorts depending on the inclusion criteria for each cohort. Cohort 1: Patients scheduled for hepatic vein pressure gradient (HVPG) measurements will subsequently undergo two consecutive SHAPE (subharmonic aided pressure estimation) procedures using different ultrasound contrast agents (Definity \[Lantheus Medical Imaging, N Bilerica, MA, USA\] and Sonazoid \[GE Healthcare, Oslo, Norway\] in randomized order) to estimate portal pressures with a Logiq E10 scanner (GE Healthcare, Waukesha, WI, USA) and determine the reproducibility of the SHAPE algorithm. Cohort 2: Patients identified as having clinically significant portal hypertension (CSPH) will be monitored by SHAPE with Sonazoid for the duration of this project (18-24 months on average). These subjects will have follow-up ultrasound scans every 6 ± 2 months to check for hepatocellular carcinoma (HCC) (using the Barcelona-Liver Cancer staging system) as well as ascites and at those times a repeat SHAPE examination will be performed. Liver stiffness values will be measured with elastography as well. This cohort will examine if serial SHAPE can accurately predict development of ascites and other liver related events in patients with compensated cirrhosis undergoing routine HCC surveillance in a multi-center setting. Cohort 3: Subjects newly diagnosed with portal hypertension and starting treatment with non-selective β-blockers will be monitored with SHAPE and results compared to elastography measurements of liver stiffness with standard assessments (e.g., serum liver function tests and measurement of spleen size as well as platelet count). This cohort will establish if SHAPE can be used to monitor treatment response in patients identified with portal hypertension. Cohort 4: Patients with compensated advanced chronic liver disease scheduled for an endoscopy examination for screening of varices relative to the Baveno VI and the expanded-Baveno VI criteria as well as the AST to Platelet Ratio Index will undergo a SHAPE examination. This cohort will compare the predictive ability of SHAPE for allocating patients with compensated advanced chronic liver disease to screening of varices compared to the current standard of care.

This study integrates and evaluates a series of novel MRI methods for quantifying blood perfusion and tissue microstructure. The proposed perfusion and microstructure measures may provide biomarkers for fibrosis, cirrhosis, portal hypertension, and response to treatment. The precision of these methods will be evaluated in 110 participants, including healthy volunteers, people with chronic liver disease (CLD), and people with liver fibrosis.

This study is conducted to evaluate the pharmacokinetics and safety of INCB161734 in participants with hepatic impairment.

Greater advances are needed in two separate but related areas in healthcare: 1) the Clinical Decision Support Systems that complement the EHR use in support of routine patient care, population management and disease management; and 2) the use of the point-of-care observational data from the provider-patient encounter that support realworld medical research and healthcare quality measure assessment. Real-world evaluations of treatments of chronic diseases in the context of comorbid conditions and special populations (minorities, women, mentally ill, and those with addiction) are limited. The purpose of the OPERA database is to help address this unmet need in clinical research.

This cross-sectional study aims to determine the frequency, pattern, and predictors of liver function test abnormalities among children and adolescents with type 1 diabetes mellitus attending Assiut University Children Hospital.

This is an exploratory, international, prospective, interventional, multicenter clinical investigation that will take place in 1 Hong Kong site and 3 French sites and 309 adults patients will be included. The study objective is to assess the LSM reproducibility between the FibroScan examination performed with the Single Probe (SP) and the FibroScan examination performed with the reference probes (M and XL).

This is an European, prospective, interventional, multicenter clinical investigation that will take place in 2 French sites. 153 adults patients will be included. The study objective is to develop a new method for measuring liver stiffness using FibroScan.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide and is frequently diagnosed at an advanced stage, resulting in limited therapeutic options. Despite the advances in immunotherapy, a substantial proportion of patients fail to respond adequately due to mechanisms of immune resistance. The gut microbiota plays a crucial role in modulating the response to immune checkpoint inhibitors (ICIs), and fecal microbiota transplantation (FMT) has demonstrated the ability to enhance their efficacy in other tumors, such as melanoma. In patients with HCC and cirrhosis, intestinal dysbiosis, characterized by a reduction in beneficial bacteria (e.g., Bifidobacterium, Akkermansia) and increased inflammation, is associated with an immunosuppressive profile. Furthermore, a dysbiosis index has been correlated with response to ICIs. In this context, FMT represents a promising strategy to enhance the efficacy of immunotherapy in HCC, although data regarding its efficacy and safety are still limited.

Primary sclerosing cholangitis (PSC) is a rare liver disease that damages the liver's bile ducts. Bile ducts are tiny tubes that carry bile from the liver to the small intestine. Bile is a liquid produced by the liver that helps us absorb and use the nutrients in the food we eat. In people with PSC, the bile backs up into the liver and will damage it, causing scarring of the liver. The purposes of this study are to: * Collect medical and other data to learn more about PSC, how it progresses, and identify factors that may cause the disease to progress more quickly. * Ask questions about how PSC symptoms affect your child's life to learn more about its impact on your child's daily functioning * Children with PSC who are seen at one of the participating clinical sites in the Childhood Liver Disease Research Network (ChiLDReN) will be asked to contribute information, DNA, and other specimens. The information and specimens will be available to investigators to carry out approved research aimed at learning more about the possible causes and long-term effects of PSC.

Advanced liver disease is a serious illness that disproportionately affects Veterans, many of whom hope for curative liver transplantation. However, too few receive a transplant and most continue to suffer from increasing symptoms and hospitalizations. The proposed project uses a whole person, Veteran-centered approach that identifies Veterans with advanced liver disease using a population-based health management system and integrates curative and early supportive care using a telemedicine-based nurse care counselor to (1) discuss patient's understanding of illness severity and prognosis, (2) identify priorities and care preferences and (3) align curative and supportive care options to achieve patient priorities. Study outcomes include changes in (1) rates of consideration for liver transplantation, and (2) completion of serious illness discussions. Findings will inform adaptations to the intervention and facilitators for its dissemination.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease globally. While weight loss through lifestyle modification is the standard treatment, most patients regain weight limiting ultimate improvement in liver disease. On the other end of the spectrum, bariatric surgery has shown promise in the treatment of MASLD/metabolic dysfunction-associated steatohepatitis (MASH) due to its efficacy in inducing weight loss. Nevertheless, its adoption has been hindered by the perceived invasiveness of surgery. Over the past decade, endoscopic sleeve gastroplasty (ESG) has gained recognition as a promising minimally-invasive approach to weight loss. The procedure involves utilizing a Food and Drug Administration (FDA)-authorized endoscopic suturing device to reduce the gastric volume by 70%. Studies reveal that ESG is associated with approximately 18.2% weight loss at one year after the procedure, with sustained results for at least 10 years. Nevertheless, the effect of ESG on MASH remains unknown. In this study, the investigators will compare ESG + lifestyle modification versus lifestyle modification alone in treating histologic MASH. The study will randomize patients to one of two different treatment options: ESG + lifestyle modification or lifestyle modification alone.

This study will be conducted to assess the safety and pharmacokinetics of INCB123667 when administered orally to adult participants with moderate or severe hepatic impairment.

The main objective of this study is the comparison of the profile of the pro-inflammatory cytokines at the patients suffering from an alcoholic hepatitis to that of two groups witnesses: patients suffering from an alcoholic cirrhosis and unhurt patients of chronic liver disease

This study is led by the Department of Hepatobiliary Surgery of the First Affiliated Hospital of the University of Science and Technology of China (USTC), in close collaboration with multiple participating centers nationwide. The primary objective is to establish a standardized, large-scale clinical cohort database specifically for metastatic liver cancer. By collecting comprehensive data on patient demographics, primary tumor characteristics, systemic therapies, and local interventions, this registry aims to elucidate the clinical patterns and prognostic factors of secondary liver malignancies. This database will serve as a robust platform for conducting high-quality real-world studies and advancing evidence-based clinical research in the management of metastatic liver cancer.

The goal of this clinical trial is to learn if the robotic surgical system producted by Shenzhen Edge Medical Company has a non-inferior textbook outcome in liver surgery in the field of remote surgery compared to local robotic surgery. It will also learn about the safety of remote liver surgery. The main questions are: Does remote liver surgery not lower the textbook outcomes in liver surgery compared to the local robotic surgery? What complications do participants have when taking remote liver surgery? Investigators will compare remote liver surgery to local robotic liver surgery to see if remote liver surgery doesn't lower the textbook outcome in liver surgery. Participants will: Undergo remote or local robotic liver surgery according to the random program; Visit the clinic in 3, 28 and 42 day after surgery for checkups and tests; Keep a diary of their postoperative complications.

This is a prospective, single-arm, non-randomized interventional study nested within the existing ELEGANCE cohort. Patients eligible for the RE-BALANCE study will be selected from the ELEGANCE cohort based on predefined high-risk criteria, specifically a low 12-non-hydroxy/12-hydroxy bile acid ratio indicative of elevated hepatocarcinogenic risk. The study comprises Baseline Assessments (Visit 1), Intervention Visits (Visit 2-8), and Follow-up Assessments (Visit 9-11).

A multicenter, open-label, randomized, controlled study. It is proposed to evaluate the treatment plan of receiving 930mg polyene phosphatidylcholine injection one day before the operation, twice a day, and 930mg polyene phosphatidylcholine injection twice a day,combined with 100mg of magnesium isoglycyrrhizinate injection once a day,from the 1st to the 5th day after the operation. Compared with the monotherapy regimen of no liver protection treatment before the operation and receiving magnesium isoglycyrrhizinate injection 100mg once a day from the 1st to the 5th day after the operation.The efficacy and safety of treating postoperative liver function injury in patients undergoing laparoscopic hepatectomy for hepatocellular carcinoma were compared.

This single-center, non interventional cohort study investigates whether chronic iron overload influences the incidence of liver complications in adults who are at least 10 years beyond allogeneic hematopoietic stem cell transplantation (allo HSCT). Approximately 400-500 survivors transplanted at Hôpital Saint Louis between January 2004 and December 2014 will be evaluated. Transplant characteristics, prior iron overload therapy, and historical hepatic events will be collected through the Promise database. At the same time, the prospective visit will include laboratory panels and non invasive liver stiffness measurement by FibroScan or shear wave elastography. The study's primary objective is to assess the impact of iron overload on the incidence of hepatic complications in patients more than 10 years after an allogeneic hematopoietic stem cell transplantation. Secondary aims include describing the spectrum and frequency of hepatic complications, determining risk factors (including graft versus host disease, conditioning regimen, and comorbidities), and evaluating the long term effectiveness of previous iron reduction treatments (phlebotomy or chelation). Results will clarify whether monitoring and treating iron overload in long term allo HSCT survivors can prevent late hepatic morbidity.

The goal of this study is to find out if quality assessment by normothermic machine perfusion can be used to safely increase the number of usable donor livers, helping more people get transplants faster and with better results. This process keeps a donated liver working outside the body before transplantation, allowing surgeons to assess whether livers previously considered unsuitable can still be used. The main questions this study aims to answer are: * Does this method help patients get a transplant sooner? * Can this method make more livers available for transplant? * Does it improve survival and health after transplant? Participants in this study must be on the waiting list for a liver transplant with a ReMELD-Na-Score of 21 or less (equivalent to MELD ≤25) and must not qualify for certain special exceptions. Participants will be randomly placed into one of two groups: * Experimental group: In addition to regular organ offers, these participants may receive a liver that was initially not considered for transplantation but meets quality standards after at least four hours of machine perfusion. * Control group: These participants will receive a liver through the usual transplant process. The main measure of success is how quickly participants receive a transplant. Researchers will also look at other important factors, such as survival rates, quality of life, hospital stay, and complications after transplant. This study may help improve liver transplantation by making better use of available donor livers, reducing waiting times, and improving patient outcomes.

The purpose of this study is to identify individuals who have suffered a liver injury arising as an idiosyncratic reaction to a prescription drug or a complementary and alternative medicine. Recently added acute cases enrollment that meets criteria to the protocol. Also added Fibroscans to the protocol that will be completed at baseline and follow-up on chronic subjects.

The purpose of this study is to assess the safety of autologous Adipose-Derived Mesenchymal Stem Cell for use in End-Stage Liver Disease patients undergoing the creation of a duct-to-duct anastomosis during Living Donor Liver Transplantation.

With the accumulation of multimodal clinical data such as medical imaging and electronic health records (EHRs), efficient utilization of multi-source information to achieve precise diagnosis and intelligent decision-making has become a core direction of medical artificial intelligence (AI). Although traditional unimodal algorithms have yielded outcomes in specific tasks, their inability to model the semantic correlations among imaging, textual, and laboratory data leads to insufficient stability and limited interpretability of diagnostic results, making it difficult to meet the needs of comprehensive decision-making in complex clinical scenarios. In recent years, multimodal large models have demonstrated excellent cross-modal understanding and knowledge transfer capabilities in natural images and general vision-language tasks, providing a new paradigm for medical AI. However, direct application in medical scenarios still faces challenges: first, the medical semantic system differs significantly from general language models, hindering the accurate representation of disease characteristics and imaging details; second, the complex morphology of lesions and uneven sample distribution in medical data increase the difficulty of model generalization; third, clinical data involves privacy, so data security and ethical compliance serve as prerequisites for research. The research on medical multimodal large models aims to integrate multi-source heterogeneous medical data, establish a unified semantic representation and reasoning mechanism, and realize full-process intelligent analysis including disease identification and lesion localization. This approach can not only improve the efficiency and accuracy of clinical diagnosis but also provide clinicians with interpretable and traceable auxiliary decision support, boasting broad application prospects. Based on the hospital's clinical data resources and the research team's algorithmic foundation, this study intends to construct a multimodal large model system for medical imaging diagnosis, enabling closed-loop intelligent analysis from multimodal information fusion to diagnostic report generation. The research will strictly adhere to medical ethical standards, protect patients' right to information, right to privacy, and data security. Before the official launch of the project, ethical review must be passed, and relevant regulations shall be followed to ensure the unity of scientific research and ethics, laying a compliant foundation for subsequent clinical validation and promotion.

The purpose of this trial is to see if providing patients with alcohol-related liver disease with tailored alcohol use treatment options will increase engagement with treatment and correct possible misconceptions.
