Active clinical trials for "Liver Cirrhosis"

Use of Ribavirin could affect hematologic profile of the patients negatively. With advent of new antiviral therapy, the preexisting hematologic changes may alter or corrected after treatment. However, this point is still not properly studied.

Hospitalized cirrhotic patients are at high risk of complications and adverse outcomes. This study aims to determine the current practice and outcomes in these following areas: Community-acquired infections Nosocomial infections Development of second infections Factors predicting ICU care, organ failure, death, and disability Patterns and adequacy of albumin use in infected and non-infected patients Per and post-liver transplant outcomes Quality-assurance and adequacy of management of complications of cirrhosis such as hepatic encephalopathy, variceal bleeding, hyponatremia, and hypernatremia Regional variations in outcomes and therapeutic strategies

Liver biopsy is the reference method for the measurement of liver fibrosis. But it has many limitations, such as sampling error and individual variation in interpreting the results. Currently, serum liver fibrosis markers have been employed as non-invasive diagnosis of liver fibrosis and evaluation of the severity of liver fibrosis. They include laminin (LN), hyaluronic acid (HA), collagen type IV (CIV), and N-terminal propeptide of collagen III (PIIINP). However, few study was conducted to explore the role of these liver fibrosis markers in evaluating the prognosis of liver cirrhosis. Our hypothesis is that LN, HA, CIV, and PIIINP in combination or alone can predict the prognosis of liver cirrhosis.

A single-center randomized controlled study comparing endoscopic or interventional therapy guided by the hepatic venous pressure gradient (HVPG) , to standard endosopic variceal ligation plus nonselective beta-blocker therapy (NSBB) in patients with esophageal varices due to liver cirrhosis with a history of esophageal variceal hemorrhage.Primary study outcome of the study is variceal rebleeding episodes occurring within the first years after interventions. Second study outcomes of the study are hepatic encephalopathy occurrence, mortality occurrence, liver transplantation or other cirrhosis-related complications.

aimed to develop a scoring system to assess risk of developing HCC in a large cohort of chronic hepatitis C (CHC) patients with advanced hepatic fibrosis (F3) or cirrhosis (F4) with sustained virological response (SVR) after receiving direct acting antivirals (DAAs).

The investigators will assess the ability of ultrasound (US) to measure liver stiffness (cirrhosis) and liver fat content (steatosis).

A defect of the immune response has been described in patients with severe liver disease. This immune-paresis is partly driven by a compensatory anti-inflammatory response following a systemic inflammatory response syndrome and affects the innate immune response. The innate immune defect has been described in patients with advanced cirrhosis and more significantly in patients with acute liver failure or acute on chronic liver failure (ACLF). The monocytes/macrophages pro-inflammatory response and finally the antimicrobial response are thus strongly impaired, leading to higher sepsis risk. The monocytes/macrophages phenotype associated with these functional alterations has been widely described, with a weaker expression of Human Leukocyte Antigen - DR isotype (HLA-DR) on the monocytes surface, correlated with poor outcomes. The low monocytic expression of HLA-DR, its functional and clinical impact has been widely described in the context of septic shock with similar pathophysiological mechanisms. Liver transplantation (LT) is often the only therapeutic option for patients with advanced liver failure. Post-transplant survival of the most severe patients is similar to the survival in the whole population of LT patients, but the complication rate remains higher, with a major risk of infection. Currently used immunosuppression protocols do not take into account the quality of pre-transplant immune response. Some treatments, such as corticosteroids, which are widely used for the induction of post-transplant immunosuppression, may affect the innate immune response. However, it has been shown that low expression of post-transplant monocyte HLA-DR was associated with a greater risk of septic complication. The general objective of this study is to focus on the evolution of a robust marker of immune dysfunction, HLA-DR monocyte expression, before and following LT, and to analyse its post LT expression depending on the level of pre-transplant expression as well as its association with post-transplant complications. This study will bring new insights for the design of a prospective study on the relevance of adapting post-transplant immunosuppression protocols to HLA-DR expression on monocytes surface, which is a robust marker of the innate immune response. Evaluation of innate immune dysfunction pre-LT by quantification of monocytic HLA-DR expression and monitoring of its post-LT kinetics may be relevant for assessing post-transplant immune status and adapting immunosuppressive therapy. A descriptive, observational study associating clinical and biological data is needed to confirm the relevance of HLA-DR expression quantification on the surface of monocytes in a population of selected patients, before and after LT. These data will allow setting up a prospective interventional study reporting the possible benefit of post-transplant immunosuppressive treatment modulation, according to the HLA-DR monocyte dosage and its kinetics evolution. The main objective of this study is to describe the association between evolution of monocytic HLA-DR expression on monocytes/macrophages surface during the first month after LT and the occurrence of one of the 2 following clinical events reflecting a post LT immune dysfunction (acute cell rejection and sepsis).

The aims of this study are to assess the performance of the non-invasive Electrical Impedance Technology (EIT) in evaluating the liver fibrosis stage in patients with chronic liver diseases, in comparisons with a liver biopsy and/or Shear wave elastography and Liver Ultrasonography. The second aim is comparing between Liver Ultrasonography and Electrical Impedance Technology (EIT) to quantify the hepatic steatosis grade in patients with Non Alcoholic Fatty Liver Disease (NAFLD) .

Malnutrition and muscle wasting are common consequences of life-threatening, chronic diseases of the gastrointestinal tract. Such diseases include liver cirrhosis, chronic pancreatitis and short bowel syndrome. Malnutrition and muscle wasting increase the risk of complications, reduce the life expectancy and impair the quality of life. The development of malnutrition and muscle wasting is different, as is the diagnosis and nutritional treatment. There are also different mechanisms of origin for the underlying diseases. The aim of the study is to compare data related to nutrition and physical condition of patients with liver cirrhosis, chronic pancreatitis and short bowel syndrome. Malnutrition and muscle wasting within the specific diseases will be characterized and possible correlations will be identified. For this, malnourished and non-malnourished patients of the different diseases are compared with controls patients with non-specific complaints of the gastrointestinal tract as well as with healthy study participants. Data on food intake, physical activity, body composition and body measurements as well as muscle strength and muscle function are recorded. Blood values as well as transport and barrier properties of the intestine will also be examined.

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent condition, and when fatty liver is associated with inflammation and hepatocellular injury (steatohepatitis), it can lead to fibrosis, cirrhosis, liver failure and hepatocellular carcinoma. Liver biopsy is the gold standard for NAFLD assessment but has several drawbacks. Several drugs for NASH are now in phase 2-3 trials, and if medical treatments become available, non-invasive tools to identify patients who may benefit from a therapeutic intervention will be strongly needed. Some imaging methods have shown promising potential in fibrosis and NASH diagnosis. This study aims to evaluate the diagnostic accuracy of non-invasive imaging methods, including ultrasound (US) and Magnetic Resonance (MR) techniques, in diagnosing NASH and fibrosis in patients with or at high risk of NAFLD, using liver biopsy as the reference standard. Consecutive patients with a clinical indication for liver biopsy assessment of NAFLD are enrolled in this non-inferiority study. They undergo both a liver US and a multiparametric unenhanced liver MR examination. As reference standard, histological diagnosis of fibrosis and steatohepatitis made according to the fatty liver inhibition of progression (FLIP) algorithm is used. Sensitivity and specificity of imaging parameters alone or in different combinations will be calculated with the aim of finding one or more tests with at least 90% sensitivity/specificity compared to liver biopsy.
