Active clinical trials for "Liver Cirrhosis"

Primary biliary cirrhosis (PBC) is a chronic liver disease primarily affecting middle age women. It is characterized by immune-mediated damage to cells lining the tiny bile ducts within the liver. Although the underlying cause of PBC is likely to be multifactorial, the epidemiologic/population data indicate a very important role for genetic predisposition, meaning that the disease seems to run in families. Susceptibility genes for PBC have not been identified possibly due to limitations such as small sample size in prior studies. The primary objective of this study is to identify these genes. This study involves obtaining clinical and demographic data as well as collecting DNA samples from patients and their parents, and siblings to screen for a select set of candidate genes as well as the full genome for variants associated with PBC.

This a prospective observational study in Chronic Liver Disease patients admitted or seen in OPD, Department of Hepatology, Institute of Liver and Biliary Sciences, India. The study will be conducted in a period of three months starting September 2016 in sample size of 80 . A detailed proforma including history and examination and routine blood investigations will be noted. The patients will undergo close follow up at 0, 7, 15, 30, 45, 60, 90 days and similar activities will be repeated at every visit.

Liver fibrosis is the main feature in early chronic liver diseases. If identified early, liver fibrosis is reversible. The current gold standard for diagnosing liver fibrosis is invasive liver biopsy. Existing non-invasive methods still have significant limitations. T1rho imaging is a promising non-invasive technology evaluating liver fibrosis. It does not require exogenous contrast agent or extra hardware. However, it remains challenging to perform T1rho measurements of the liver. The rich blood signal in the liver introduces quantification errors of liver parenchyma. The existing black blood MRI technologies are based on Cartesian FSE acquisitions, which are not optimal for liver imaging. The residual blood signal is often observed which confounds the measurement. Current T1rho measurement of the liver is mostly performed in two-dimension. 3D coverage of liver is desirable. However, 3D T1rho imaging of liver suffers from long scan time due to increased spatial coverage, reduced scan time efficiency from motion compensation, and high specific absorption rate (SAR). The investigators aim to overcome these challenges by developing 3D T1rho imaging technologies based on magnetization prepared spiral FSE acquisition. Compared to Cartesian FSE, Spiral FSE traverses k-space more efficiently per unit of time, and has reduced SAR due to significantly decreased number of radiofrequency pulses in the echo trains. Spiral acquisition has zero gradient moment at the kspace center, which substantially reduces its sensitivity to respiratory motion. The residual motion manifests as benign incoherent artifacts in the image domain rather than detrimental structured artifacts. Differently to Cartesian FSE, Spiral FSE provides flexibility to design and optimize flow-sensitizing gradients throughout the echo trains to achieve superior suppression of blood signal. The investigators will evaluate the proposed pulse sequences in both healthy controls and patients with liver fibrosis. This project will provide new black blood imaging technologies and a 3D diagnostic tool for early detection of liver fibrosis. This will improve clinical outcomes for patients with chronic liver disease, and provide a springboard for further development of MRI technology for other purposes.

The study will be conducted on patients admitted to Department of Hepatology from MARCH 2015 to DECEMBER 2016 at ILBS, New Delhi.All patients presenting to ILBS fulfilling the inclusion criteria will be included in the study and will be categorized and evaluated. The patient will followed over a period of 3 months.

This is a prospective study designed to examine the role of transient elastography as a predictor of clinical decompensation in patients with early cirrhosis. The study objective is to determine if changes in measurements of liver stiffness with transient elastography can identify patients that will have a more rapid progression of cirrhosis and the development of clinical decompensation. The target population is patients with early stage, well-compensated cirrhosis. Participants of this study will be asked to complete the following procedures: read and sign the informed consent, medical records review (complete medical history, physical examination, laboratory evaluation, endoscopic findings, radiographic findings), undergo transient elastography to measure liver stiffness every three months until the development of clinical decompensation (ascites, variceal bleeding, hepatorenal syndrome, overt hepatic encephalopathy) for up to 2 years.

The purpose of this study is to determine the extent to which severe burn injuries affect the morphology and function of liver, pancreas and thyroid. The evaluation of the liver will be performed non-invasively with liver fibrosis scores based on standard blood parameters and the measurement of liver stiffness (correlated with liver fibrosis) and controlled attenuation parameter (CAP, correlated with hepatic steatosis) via transient elastography (FibroScan©, Echosens SA, Paris, France). The thyroid and the pancreas will be assessed via ultrasound (GE Medical Systems, Waukesha, USA) and standard blood parameters, respectively.

This study evaluates the supervivence of cirrhotic patients that develop portal vein thrombosis in comparison to cirrhotic patients that do not develop portal vein thrombosis.

The investigators will investigate the usefulness of biannual ultrasonography versus annual non-contrast magnetic resonance imaging for surveillance of hepatocellular carcinoma in single arm patients.

The purpose of this study is to perform a multicentre registry of cirrhotic patients who had been submitted to an imagining technique in recent years (angio-CT scan or abdominal MRI), in order to collect anatomical and clinical information. The main objective will be focused on the study of portosystemic shunts and their relation with portal hypertension. Patient with liver cirrhosis submitted to an abdominal angio-CT scan or a MRI from year 2010 to 2014 will be included in the study. The chosen imaging technique will be angio-CT preferably, but MRI data will also be available. Patients will be identified in every hospital by means of the registry of coded diagnoses and the lists of complementary tests performed. Clinical and radiological data of every patient will be collected. The clinical variables will be obtained from reviewing the patient clinical history. The radiological parameters will be gathered by means of the systematic review of the angio-CT or MRI.
