Active clinical trials for "Fibrosis"

The main objective is to determine the performance of the simple eLIFT blood test for advanced liver fibrosis screening in NAFLD and/or alcoholic patients in primary care.

The project is about evaluation of albumin and midodrine versus albumin alone in outcome of refractory ascites in patients with decompensated cirrhosis. Cirrhosis is a leading cause of disability and mortality worldwide. Cirrhosis occurs in 50% of patients over 10 years. Decompensated cirrhosis carries a poor prognosis because the median survival time is about 2 years and it imposes a heavy burden on health care costs mainly due to the need for repeated hospital admission. The mortality is approximately 40% at 1 year and 50% at 2 years (12.7 per 100,000 population). A lot of times the prognosis is poor and the main factors leading to it are - AKI/HRS-NAKI, Hyponatremia, Grade of ascites-Refractory ascites, Sarcopenia, low Mean arterial pressure. Post review of the literature, it is realized that there are some gap areas - It is unknown whether combination of vasoconstrictor with albumin further decreases the need for paracentesis in patients of refractory ascites. There are no studies till date on using combination of vasoconstrictor with albumin for refractory ascites. There are no studies evaluating the prevalence and incidence of HRS-NAKI using the new definitions in patients with refractory ascites and impact of combining vasoconstrictor and albumin in improving renal outcomes in these patients.

The purpose of the study is to assess the diagnostic accuracy of Endoscopic Ultrasound (EUS) shear wave elastography in liver fibrosis staging in both normal subjects and subjects with advanced liver fibrosis/cirrhosis

The primary objective of this study is to assess the clinical performance of LIVERFAStTM In Vitro Diagnostic (IVD) Tests (Fibrosis score, Activity score and Steatosis score) in NAFLD suspected patients for staging of fibrosis and for grading of inflammatory activity and steatosis, taking as reference the liver biopsy with histological classification of the elementary lesions determined according to SAF scores (Bedossa P., Hepatology 2012). The secondary objective is to assess the performance of LIVERFAStTM for the histological definition of NAFLD, including NAFL and NASH and severe NASH

CF is a complex, inherited illness that can affect many organs of the body. The investigators have found that some patients with CF have reported more problems with memory than would be expected at their age and that patients appear to be using memory strategies to overcome memory loss. The investigators intend to objectively test memory and examine MRI images of the brain of patients with CF.

The goal of this study is to define 25(OH)D3 catabolism in CF patients using gold standard pharmacokinetics studies. Specifically, the investigators will evaluate the metabolic clearance of 25(OH)D3 among participants with CF and matched control subjects. The goal of this work is to provide the first comprehensive characterization of vitamin D metabolism in CF patients and promote novel hypotheses for subsequent studies.

High resolution computed tomography (HRCT) plays a major role in the management of idiopathic pulmonary fibrosis (IPF) by identifying characteristic lesions of usual interstitial pneumonia (UIP). Though HRCT is the standard reference to describe pulmonary structural alterations using a non invasive technique, it is nonetheless a radiating exam which provides limited functional information regarding inflammation. In this trial, the investigators aimed to evaluate whether MRI (Magnetic Resonance Imaging) using ultra-short echotime could be an alternative to HRCT in the assessment of the four morphological criteria required to define an UIP pattern. The investigators also planned to study the clinical value of the additional informations derived from MRI such as contrasts and lung perfusion using functional MRI.

The purpose of this study is to determine whether magnetic resonance imaging (MRI) using inhaled hyperpolarized 129Xe gas, and conventional contrast can help visualize impaired lung function and detect changes over time in patients receiving treatment as well as those who don't. 129Xe is a special type of xenon gas and when inhaled during MRI may be able to show areas of abnormal thickening of parts of the lungs. These images combined with images taken with injected contrast agents or other types of MRI may provide a better way to look at lung structure and function in patients with IPF. The ultimate goal is to predict how a particular patient might respond to a particular therapy and to observe such responses earlier than conventional tests. The investigators anticipate that the images acquired in this study will provide more specific information about lung disease than standard lung function tests. The use of 129Xe MRI is investigational. "Investigational" means that these tests have not yet been approved by the US Food and Drug Administration and are being tested in research studies like this one. In addition, standard MRI with contrast is not typically done as standard of care for monitoring progression of IPF, therefore, its use in this study is also considered investigational. Healthy volunteers are being asked to participate in this study because the investigators need to develop a database of functional images that are representative of healthy lungs.

This trial is a pivotal trial to validate the use of a 13 C labeled substrate called methacetin and the BreathID automatic breath testing system, for determination of cirrhosis in patients with chronic liver disease.

Antiglaucoma medication have been shown to induce subclinical conjunctival inflammation in a considerable proportion of glaucoma patients. Today, trabeculectomy still remains the gold standard as surgical treatment of medically uncontrolled glaucoma disease. However, this procedure is associated with variable possible complications, of which subconjunctival fibrosis is the most frequent one. The latter results in a non-functional filtering bleb. As a consequence, either additional interventions such as laser suture lysis, needling, bleb revision or additional IOP-lowering medication is necessary. Previous studies demonstrated a benefit of the use of topical steroids postoperatively in reducing inflammation and subsequent subconjunctival fibrosis. In this perspective, we will prospectively explore the usefulness of topical NSAID or corticosteroid therapy preoperatively as compared to placebo in subjects scheduled for first-time trabeculectomy, without interrupting topical antiglaucoma therapy. This will allow us to determine wether the impact of longterm topical antiglaucoma therapy on subclinical conjunctival inflammation which possibly result in postoperative fibrosis and bleb failure can be reversed by anti-inflammatory medication before filtering surgery.
