Active clinical trials for "Liver Cirrhosis"

Through the parameters of liver stiffness and spleen stiffness obtained by combi-elastography technique, summarize and analyze the warning index of esophagogastric variceal bleeding in patients with cirrhosis, so as to provide a new and valuable technique for clinical diagnosis.

To address the existing deficiencies in the knowledge regarding liver involvement and spectrum of clinical presentation and the impact of COVID-19 infection in patients of liver disease was planned. The present study will be a hospital based and the cases of confirmed COVID-19 infection will be evaluated in relation to liver involvement irrespective of pre-existing liver disease. The primary objective was to address the clinical presentation, biochemical alteration and outcomes of COVID-19 infection in subjects with chronic hepatitis, cirrhosis in comparison to those having infection in the absence of pre-existing liver disease

Human immunodeficiency virus (HIV) infection is a major global health issue with up to 40 million people infected worldwide. Due to highly active antiretroviral therapy, mortality related to acquired immunodeficiency syndrome (AIDS) has been reducing in the last decades. However, liver disease remains as an important cause of severe complications and death. Hepatic fibrosis progression is the main responsible for liver-related outcomes in HIV-positive patients. Co-infection by hepatitis B (HBV) or hepatitis C virus (HCV) is highly prevalence in HIV patients. Chronic viral co-infection induces faster liver fibrosis progression compared to mono-infected HIV. However, published data have been reporting presence of significant liver fibrosis in HIV without HBV or HCV infection. This might be related to direct action of HIV in hepatocytes or association with others factors, such as non-alcoholic fatty liver disease (NAFLD). NAFLD is associated with metabolic factors, such as obesity and type-2 diabetes mellitus. However, antiretroviral drugs may induce abnormal body fat distribution (lipodistrophy) and insulin resistance playing an important role on this process. Liver biopsy has been historically considered as the gold standard to evaluate liver injury. However, this painful method presents several limitations. Therefore, several non-invasive methods for estimation of liver fibrosis, such as biomarkers (APRI, FIB-4, FibroTest and FibroMeter) and transient elastography by Fibroscan, have been developed as an alternative to liver biopsy. The diagnostic performance and prognostic value of biomarkers and transient elastography have been validated in patients with chronic liver diseases. However, few data are available in HIV patients, especially in those without chronic viral co-infection. Therefore, patients, medical doctors and scientific community will be beneficiated by the future application of non-invasive methods for estimation of liver injury in clinical practice in HIV patients.

This is a single-center and prospective study to identify specific biomarker in order to predict development of decompensation in cirrhotic patients. The duration of the study is 36 months and it provides a cohort of 200 patients.

Nutritional status in patients with cirrhosis has been shown to have a direct influence on the prognosis of these patients, it is related to higher mortality and it has been linked to the developement and perpetuation of certain complications such as hepatic encephalopathy, ascites and spontaneous bacterial peritonitis. Despite the importance of nutritional status in this patients, most of the methods for its assessment are still not completely reliable or not easily accessible; therefore, evaluating nutritional status in the daily clinical practice is still a complex task.

This study is to establish a noninvasive diagnostic platform based on hemodynamic information for the assessment of liver fibrosis, liver cirrhosis and portal hypertension.

Nowadays, the morbidity of Nonalcoholic fatty liver disease (NAFLD) show ascending trend year by year, which has become an important public health problem in China. As NAFLD can progress to Non-alcoholic steatohepatitis (NASH), cirrhosis and Hepatocarcinoma, the identification and quantitative evaluation of liver steatosis and its dynamic changes are crucial. While liver biopsy is still the gold standard in the diagnosis of NAFLD, its application is limited because of the invasive procedure.The Transient Elastography(TE) combined with the Controlled Attenuation Parameter(CAP) is a new non-invasive diagnostic method for fatty liver and liver fibrosis. In order to evaluate the diagnostic value of non-invasive assessment for the degree of liver steatosis and staging liver fibrosis, this non-invasive method will be assessed by the golden standard of liver biopsy among 400 NAFLD patients.The treatment protocols will be decided by doctor and patient both (treatment protocols and medicine are not required). Blood routine, blood biochemistry, abdominal ultrasound and Transient Elastography(TE) combined with the Controlled Attenuation Parameter(CAP) are detected during the follow-up.

Hepatitis is known to induce severe liver diseases. The evaluation of the severity of liver cirrhosis is very important for the selection of appropriate treatment plan and the monitoring of patient response to treatment, accurate staging of liver fibrosis is critical because it determines the indication of antiviral treatment and prognosis of patients with chronic viral hepatitis, DWI is a particularly appealing method for the diagnosis of liver fibrosis because it is easy to implement and process, without the need for contrast agents. Apparent diffusion coefficient (ADC) has been shown to be a promising marker of fibrosis and cirrhosis.
