Active clinical trials for "Liver Cirrhosis"

Non-Alcoholic Fatty Liver Disease (NAFLD) and Non-Alcoholic SteatoHepatitis (NASH), are a frequent complication of type 2 diabetes and obesity. This disease has been linked with an increased morbidity and mortality, in particular cardiovascular disease and hepatic complications (cirrhosis and hepatocellular carcinoma). NAFLD is covered different liver damage in ascending order: steatosis, Non-Alcoholic SteatoHepatitis (NASH), fibrosis, and finally cirrhosis. Mostly, fibrosis has a determining role in the patient's status health. The fibrosis prevalence rate may reach up to 15 % of people with type 2 diabetes. The purpose of the study is to screen hepatic fibrosis for patient with type 2 diabetes. To be sure of the status of the disease, the gold standard procedure remains liver biopsy. However, it's an invasive procedure and it's a challenge to perform this kind of medical procedure to every patient with NAFLD. Some alternative procedure exists, called FibroScan that gives some indication of liver fibrosis status. Unfortunately, every diabetologist hasn't this equipment in his medical office. The investigators propose to evaluate two non-invasive biological fibrosis tests, called eLIFT and FibroMeter. The results of these two diagnostic tests will be compared to FibroScan and to liver biopsy results.

Acute kidney injury (AKI), or worsening kidney function, is a common complication after liver transplantation (20-90% in published studies). Patients who experience AKI after liver transplantation have higher mortality, increased graft loss, longer hospital and intensive care unit stays, and more progression to chronic kidney disease compared with those who do not. In this study, half of the participants will have their body temperature cooled to slightly lower than normal (mild hypothermia) for a portion of the liver transplant operation, while the other half will have their body temperature maintained at normal. The study will evaluate if mild hypothermia protects from AKI during liver transplantation.

The primary objective of the SOPRANO study is to compare two blood fibrosis tests, the eLIFT and the FibroMeter, for the screening of advanced liver fibrosis in patients with NAFLD and/or ALD from primary care centers.

Machine perfusion technology is nearing the point of rescuing discarded liver grafts in the hope of proving them to be or improving them to the point of being transplantable. However, there are no validated metrics to determine transplantability after machine perfusion. This study involves collecting biopsies from transplanted livers before and after implantation to correlate metabolite and gene expression with post-transplant function. This data will help develop a viability index for machine perfused livers.

Hepatocellular carcinoma (HCC) is the fifth most common cancer. Patients with HCCs usually have a poor prognosis. Hepatocarcinogenesis is an intricate and multistep process. Detecting and staging early HCC in patients with liver cirrhosis are still challenging for imaging techniques. Contrast-enhanced ultrasonography (CEUS) and gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) are widely used in clinical practice. EOB-MRI has advantages of high detecting rate for small lesions, high sensitivity of hepatobiliary phase and extensive image information. Sonazoid has the advantage of offering a unique post-vascular phase, also called the Kupffer phase. Therefore, malignant tumors with few or no Kupffer cells appear as contrast defects, with respect to the relatively well-enhanced surrounding liver in the postvascular phase. The diagnostic efficacies of these two imaging methods have not been well studied. Therefore, the purpose of this study is to compare the efficacies of Sonazoid-CEUS and EOB-MRI in patients with high risk of HCC, and to compare the detection ability for malignant tumors by Kupffer phase and hepatobiliary phase.

Background: During the hepatology evaluation, vibration-controlled transient elastography (VCTE) is often used as a clinical decision aid to target high-risk patients for liver biopsy. The enhanced liver fibrosis (ELF) test is expected to be approved in the US. We tested the hypothesis that making the ELF results available to the treating hepatologist will result in more appropriate and targeted use of liver biopsy in patients with elevated liver enzymes or fatty liver, and will result in more cases of advanced fibrosis/cirrhosis being diagnosed. Methods: During the hepatology evaluation for elevated liver enzymes or fatty liver at the University of Kansas Medical Center, the hepatologists (8 total) make a clinical decision on whether patients shall receive VCTE. At the end of the clinic visit, patients were enrolled and randomized to receiving an ELF test. Patients with liver biopsy within the last five years or decompensated cirrhosis were excluded. The primary outcome is the rate of a diagnosis of F3-4 fibrosis based on liver biopsy or clinical diagnosis of cirrhosis with the initiation of hepatocellular carcinoma surveillance. Four hundred fifty patients are to be enrolled over two years.

Portal hypertension (PH) is a group of syndromes characterized by abnormal changes in the portal blood flow system, mostly caused by cirrhosis. It is an important factor affecting the clinical prognosis of cirrhotic patients, and its severity determines the occurrence and development of cirrhotic complications. Clinically, measurement of portal venous pressure directly is highly invasive, and factors such as intra-abdominal pressure changes can interfere with the results, limiting its clinical application. Hepatic venous pressure gradient (HVPG) is the gold standard for assessing PH in cirrhosis. The normal range of HVPG is 3~5 mmHg, and HVPG ≥5 mmHg indicates the presence of PH. AASLD stated that HVPG ≥10 mmHg is defined as clinically significant portal hypertension (CSPH), and the risk of decompensation events is significantly increased at this stage. However, HVPG is an invasive test, which is unacceptable to some patients, such as being expensive, difficult to repeat, and poor patient compliance. Non-invasive tests for PH include serological tests, anatomical imaging and combination models. Imaging evidence of portal collateral circulation or hepatic blood flow in the portal venous system based on ultrasound Doppler, CT or magnetic resonance imaging techniques can assist to diagnose PH. In addition, elastography techniques such as transient elastography, point shear wave elastography, two-dimensional shear wave elastography and magnetic resonance elastography can be used to measure liver stiffness and spleen stiffness to assess PH. Some biochemical markers are also considered as non-invasive tests for PH. However, the available biomarkers are not yet a substitute for the HVPG accurately, and therefore, there is an urgent need for the development of biomarkers associated with HVPG in clinical practice. Metabolomics is a method to analyze the concentrated changes of endogenous small molecule metabolites under the combined effect of genetic, biological and environmental factors with the help of various high-throughput technologies. Metabolites are at the end of the biological information flow, and their changes are the ultimate expression of the information from the coordinated action of each group, objectively reflecting the overall changes of the organism. Currently, metabolomics techniques have been widely used in screening biomarkers of liver diseases. Wang et al. applied GC-TOF/MS and UPLC-QTOF/MS to study the urinary metabolomics of patients with hepatitis B cirrhosis and showed that α-hydroxymaurolate, tyrosine-betaine, 3-hydroxyisovaleric acid, knife-serine succinate, estrone and GUDCA were significantly altered in different Child-Pugh grades of cirrhosis, suggesting that these metabolites are potential biomarkers to identify different pathological stages of cirrhosis. Therefore, metabolomics is a reliable and valid tool for biomarker discovery. In conclusion, this study analyzed significantly altered metabolites in patients with hepatitis B cirrhosis using metabolomics to explore potential differential metabolites that are highly correlated with HVPG. Further, serological biomarkers were identified as an alternative to HVPG testing through model construction and validation.

The main trial objective, is to ascertain whether the transport activity, given by the maximum concentration (Cmax) and the area under the curve (AUC0-24) values for the different components in the transporter cocktail are similar or different in F4 liver cirrhosis patients on standard therapy compared to healthy subjects.

Haemorrhoids are the most common proctologic disease, affecting up to 36% of people in the developed world. Sclerotherapy is defined as the injection of sclerosing agents at the apex of the internal hemorrhoidal complex, above the dentate line, leading to scarring, fibrosis, and fixation of the hemorrhoids. Sclerotherapy as a treatment of internal hemorrhoids has been used for a long time by surgeons, using proctoscopic exposure. Even though flexible instruments can be expected to have better manoeuvrability and target site exposure. There is no consensus amongst the major guidelines as to which grade of haemorrhoid that sclerotherapy should be used, whether it is equivalent or inferior to rubber bad ligation (RBL), whether sclerotherapy should be used at all for the treatment of IH, what is the effect of PHT on hemorrhoid prevalence and propensity to bleed, differentiation of internal hemorrhoids from rectal varices, data on EBL or EST in cirrhotics with hemorrhoids, safety of endotherapy with underlying coagulopathy and concerns for infectious complications.

This clinical trial is a Phase 1, multiple administration, dose-escalasion clinical trial of human umbilical cord-derived mesenchymal stem cells for the treatment of decompensated cirrhosis. The primary objective of this study is to assess the safety of intravenous infusion of human umbilical cord-derived mesenchymal stem cells in patients with decompensated cirrhosis.
