MRI to Assess the Effect of Non-selective Beta-blocker in Patients With Cirrhosis
Portal HypertensionCirrhosis5 moreBackground: Standardization and new therapeutic treatments of variceal bleeding has significantly reduced the mortality the last 25 years, but there is still a high 6-week mortality around 15-20% and 1-year mortality of about 40%. Cirrhotic patients without prophylactic treatment suffer a risk of 60% of re-bleeding within the first year after the first bleeding episode. Variceal ligation and NSBB are the standard therapy as secondary prophylaxis, while only non-selective beta-blocker (NSBB) is offered as first-line therapy in primary prophylaxis. If portal pressure is reduced to a value below 12 mmHg or by 20% (10% if assessed by intravenous administrations), the risk of bleeding is substantially reduced, but not all patients respond to the treatment with propranolol (40-50%). Hence, patients who are non-responders to NSBB should be offered alternative treatment with e.g. carvedilol, which is a combined alpha-beta-receptor blocker or endoscopic band ligation. Currently, the response to NSBB is assessed invasively during a liver vein catheterization (LVC). Unfortunately, only a few centres in the world can perform this procedure and there are no reliable non-invasive alternatives to assess the respond to NSBB, which is of extreme importance, since non-responders have three fold increased risk of a new variceal bleeding episode. Aim: In general the aim of the project is to develop faster and non-invasive methods to evaluate portal hypertension and individual pharmacological response of NSBB in patients with cirrhosis. Furthermore, we expect to detect changes in liver and spleen stiffness as measured by MR-Elastography (MRE) after NSBB and that these depend on the drug-related effects on portal pressure. Study design and patients: 39 patients with cirrhosis and esophageal varices that require NSBB (propranolol) treatment. Patients are assessed with LVC, MR-scans, echocardiography and biochemical tests. LVC is the gold standard method to test if patients respond to propranolol treatment. At visit 1. the response to NSBB is defined as a reduction of HVPG ≥10%, or to a HVPG< 12mmHg after intravenous NSBB administrations during LVC. MRI-scan with intraveneus NSBB administration is performed at visit 2. Minimum 5 days of NSBB wash out between visit 1 and 2.
Gastric Variceal Ligation Versus Gastric Variceal Obturation for Secondary Prophylaxis of Gastric...
Gastroesophageal VaricesLiver CirrhosisThe investigators establish a randomized controlled clinical trial, comparing the efficacy and prognosis of GVL and GVO in secondary prevention of GVs, especially in patients with portosystemic shunting, and exploring the endoscopic treatment selection of different types of GVs. Outcome expectations: Compared with glue injection, endoscopic ligation for secondary prevention of gastric varices is safe and effective, especially in patients with portosystemic shunting.
The Effects of Early Enteral Nutrition on Endoscopic Therapy of Esophagogastric Varices in Liver...
Liver CirrhosisEsophageal and Gastric VaricesThe purpose of this study was to evaluate the safety of early enteral nutrition on endoscopic therapy of esophagogastric varices in Liver Cirrhosis ,and to assess the impact of different eating times on patients, so as to determine the best time for patients to obtain nutrition after surgery.
NAFLD and Liver Fibrosis in Obese Adolescents
Liver FibrosisLiver Steatosis1 moreNonalcoholic fatty liver disease (NAFLD) is a chronic liver disease resulting from excessive fat accumulation in the liver. Due to its close association with obesity, it has become the most common liver disease in children in the United States. NAFLD can result in progressive fibrosis and lead to end-stage liver disease. Best practices in management of pediatric NAFLD are not clearly defined. Our aim is to clarify the natural history of NAFLD in obese children after weight loss surgery compare to lifestyle intervention. Our secondary aim is to investigate the added value of elastography for the screening and diagnosis of NASH with fibrosis.

Efficacy Study Of Oral Glecaprevir/Pibrentasvir Tablet In Pediatric (12 Years and Older) And Adult...
Hepatitis C Virus (HCV)Hepatitis C Virus (HCV) infection is among the most common of all chronic liver diseases. HCV predominantly affects liver cells and causes the liver to become inflamed and damaged. This can lead to cirrhosis (scarring of the liver) and liver cancer leaving trial participants with need for liver transplant. The purpose of this study is to see how effective Glecaprevir/Pibrentasvir (GLE/PIB) is in a real world setting of participants with chronic HCV genotypes 1 to 6 and liver cirrhosis who have never received any treatment for HCV. GLE/PIB is a drug developed for the treatment of HCV infection. This is a prospective (future), observational study in treatment-naive (those who have not received treatment) participants with HCV genotypes 1 to 6 and compensated cirrhosis. All study participants will receive GLE/PIB as prescribed by their study doctor in accordance with approved local label. Pediatric (12 years and older) and adult participants with a diagnosis of HCV genotypes 1 to 6 and compensated cirrhosis will be enrolled in the study in Russian Federation. Participants will receive GLE/PIB tablets to be taken by mouth daily according to their physicians' prescription. The total duration of the study is 20 weeks, with a treatment period of 8 weeks and a follow up period of 12 weeks. There is expected to be no additional burden for participants in this trial. All study visits will occur during routine clinical practice and participants will be followed for 12 weeks.

ADAMTS-13 and Von Willebrand Factor Levels and Activities in Children With Cirrhosis and/or Portal...
Coagulation DisorderCirrhosis1 moreHemostasis-related disorders are common in cirrhosis and portal hypertension. However, it is not known whether the net effect of changes in hemostasis in the sense of predisposition to hemorrhagic or thrombotic state. It is suggested that increasing the concentration and activities of Von Willebrand factor (vWF) and decline ADAMTS-13 (A Disintegrin and Metalloproteinase with Trombospondin type 1 motif, member 13) may cause thrombophilic changes in cirrhosis and portal hypertension. The aim of this study was to investigate the changes in ADAMTS-13 (A disintegrin and metalloproteinase with thrombospondin motifs 13) and von willebrand factor (vWF) levels and activities in patients with cirrhosis and portal hypertension.
The Utility of Breath Biopsy as a Screening Tool for HCC
HCCCirrhosis1 moreThe aim of this pilot study is to examine whether there is a discriminating ability of the breath sample analysis to capture biomarkers specific to the HCC in the breath of affected individuals. If positive, our research could open up a new horizon for cost-effective and feasible screening tools.
Relationship Between HbA1c and Chronic Glycemia in Patients With Cirrhosis
CirrhosisDiabetes Mellitus1 moreCirrhosis and advanced liver disease have been associated with an increased risk for hyperglycemia and type 2 diabetes mellitus (T2DM). The diagnostic yield of common tests used to define diabetes and insulin resistance in the general population differs significantly from the one observed in patients with liver disease. Glycosylated hemoglobin A1c (HbA1c), a reliable test to assess chronic glycemia and recommended both for the diagnosis and monitoring of T2DM, is neither accurate nor reliable in patients with cirrhosis. A validation study has not been performed to define its true usefulness in the setting of cirrhosis. The study aims to determine the level of HbA1c that better corresponds to the diagnosis of T2DM - as determined by an oral glucose tolerance test (OGTT) - and to correlate the levels of HbA1c with the average glucose over a 12-week period in patients with cirrhosis and known T2DM, in cirrhotic patients with different degrees of liver impairment as compared to patients with T2DM and no liver disease.
