Active clinical trials for "Liver Cirrhosis"

The purpose of this study is to determine the effect of transjugular intrahepatic portosystemic shunt on gut microbiota and associated inflammatory factors in cirrhotic patients.

AIM To evaluate the role of real time elastography (ARFI and Hitachi elastography) in noninvasive diagnosis of liver fibrosis in patients with chronic hepatitis

This study is intended to be a prospective observational study at multiple sites, not a randomized controlled trial (RCT). The uses of the biomarkers has been approved by government regulations and adopted for surveillance programs in some countries, thus an RCT which compares patients followed by US alone with patients followed by both US and the biomarkers would raise an ethical conflict, especially in countries where the biomarkers have been routinely used. For this study, enrolled patients will be followed by US and the biomarkers at regular intervals and classified after completing the study to evaluate the clinical effectiveness of the biomarkers. The comparisons of sensitivity, specificity, and other parameters with respect to tumor characteristics will be made among US alone, the biomarkers, and combined use of US and the biomarkers. Also economical effectiveness of using the biomarkers will be investigated in this study. Requirement status is monitored every month.

Primary Objective: To evaluate the long-term outcomes including liver related morbidity, mortality and hepatocellular carcinoma (HCC) development as compared to those of historical control with interferon(IFN)-based treatment. Secondary Objective: To access liver fibrosis progression/regression in CHC patients after sofosbuvir-based treatment. To investigate the long-term outcomes of extrahepatic manifestations of the sofosbuvir-based treated cohort as compared to their pretreatment status.

Patients with cirrhosis of viral etiology (HCV/HBV); Patients with cirrhosis of any other etiology (alcohol, idiopatic, autoimmune). Planned Number of cirrhotic subjects 200 patients Inclusion Criteria Subjects (18 yr old) with liver cirrhosis of any etiology, Exclusion Criteria All patients should not have hepatocellular carcinoma or other malignant tumors, they should not be treated with anticoagulant / antiplatelet agents, not affected by PVT already diagnosed and not suffering from congenital coagulation disorders (haemophilia A / B, von disease Willebrand, another congenital deficiency of coagulation factors) or severe thrombocytopenia (<30,000 Plt / μL). Subject has participated in another clinical study within 30 days prior to study enrollment or is scheduled to participate in another clinical study on cirrhosis Primary Objective To describe the prospective modification of ADAMTS-13 level and other coagulation variables (e.g. FVIII, VWF:Ag/VWF:act) in cirrhotic patients during 18 months from the enrolment and to verify their predictive role as biomarker of development of portal vein thrombosis (PVT) Secondary Objectives To describe prospectively the modification of ADAMTS-13 level as a function of the etiology of cirrhosis Statistical analysis The total duration of the study will be of 12 months. The sample size of 200 subjects will be selected as a feasible number of patients to be recruited in a period of six months. The patients will be consecutively enrolled and followed for 18 months. As a result, in a follow up period of 18 months about 20-25 cases of PVT are expected. Continuous variables will be expressed as means ± standard deviations. In addition to descriptive statistics (location parameters), univariate analysis will be performed on each parameter and development of PVT during the follow up period. In previous observational studies both 1) a reduced PV flow [prospectively] and 2) a reduction of ADAMTS-13 are significantly associated with PVT. These associations will be investigated prospectively and analyzed simultaneously by a multivariate analysis and ROC curve to establish the sensitivity and specificity of these parameters as predictors of PVT development. Analyses will be performed using available data

The spleen could be considered a neglected organ. To date, it has been deemed an ancillary organ in portal hypertension or an organ localization in lymphoproliferative diseases. Hypersplenism is a common disorder characterized by an enlarged spleen which causes rapid and premature destruction of blood cells. It can result from any splenomegaly. It is most common with splenomegaly secondary to portal hypertension and hematological disorders. Portal Hypertension is an important cause of splenomegaly in most tropical countries This work will involve a series of studies aiming to: Assess the prevalence and pattern of hypersplenism, and grade the severity of cytopenias in patients with cirrhosis and portal hypertension. Elucidate the relationship between hypersplenism, in these patients, and: The severity of liver cirrhosis as assessed by Child's and the Model of End-stage Liver Disease (MELD) scores. The presence and grade of gastroesophageal varices as assessed by upper endoscopy. The presence of hepatocellular carcinoma Portal hemodynamics and portal vein thrombosis as assessed by Doppler Ultrasound. Test the hypothesis that leucopenia in cirrhotic patients may be caused, at least in part, by apoptosis of polymorphnuclear leucocytes.

patient with liver cirrhosis was supposed to have autoanticoagulation which approved to be wrong, with absence of conventional method to detect all abnormalities in coagulation state. Thromboelastography (TEG) give a broad picture for the coagulation defects. In addition to that no guidelines prescribed anticoagulants for venous thromboembolism in cirrhotic, so the investigators will do a study to demonstrate frequency and risk factors for acute venous thromboembolism in cirrhotic patients, find a conventional laboratory method and test TEG to assess risk of thrombosis in cirrhotic patients.Also, to validate current algorithm for use of anticoagulant and antiplatelet for thromboembolism for non cirrhotic in cirrhotic patients.

The aim of this study is to evaluate the diagnostic performance of FEUrea for the differential diagnosis of AKI in patients with cirrhosis and ascites Specifically, the ability of FEUrea to distinguish between ATN versus Pre renal azotemia and HRS.

This is a national, investigator-initiated, multicenter, prospective, observational, web-based registry in hospitalized patients with cirrhosis across China. The overarching aim of this study is to investigate the epidemiology and clinical impact of bacterial/fungal infections in hospitalized patients with liver cirrhosis in China within the collaborative network. We also aimed to build up the national prospective cohort of hospitalized cirrhosis in China to stand in the future for the backbone of various research programs focused on infection, other complications of cirrhosis, organ failure, the ACLF syndrome, end-stage liver disease and beyond.

The study aims to evaluate the feasibility of transnasal endoscopy in patients with portal hypertension, cirrhotic and non-cirrhotic. The incidence of the procedure's adverse effects, the patient's tolerance and his/her opinion about the exam are analyzed. In addition, the interobserver matched for the discoveries found in the study is carried out.
