Active clinical trials for "Fibrosis"

The major causes of morbidity and mortality in Cystic Fibrosis (CF) are linked to the process of chronic inflammatory of the airway, leading to the progressive damage of the small bronchioles and subsequently to the proximal bronchi. A connection between weaknesses of respiratory muscles in CF and deficits of CFTR in the muscle has been established. Insufficient cough in CF patients may advance re-current respiratory infections. A voluntary cough flow volume (C-FVC) profile incorporates the characteristics of the forced expiratory flow volume curve (FE-VC). The study aims to explore the correspondence of voluntary cough-flow-volume and maximum expiratory flow-volume maneuvers in relation to disease complications in CF patients.

Pharmacokinetics of colimycin will be assessed during 12 hours after administration of 2M UI colimycin either as an aerosol or after IV injection, the administration being separated by 5 to 10 days intervals

The purpose of the study is to investigate the relationship between hypoxemia achieved during Hypoxia Altitude Simulation test and sea level values of pulmonary function, arterial blood gases, pulse oximetry and cardiopulmonary exercise test variables. In addition, to study the effect of slow walk in a hypoxic environment, comparable to slow walking along the aisle.

Main objective : This project aims to assess the educational needs of patients who received a lung transplantation or a simultaneous heart-lung transplantation for mucoviscidosis. Specific objectives : Evaluate the specific needs dependent on seniority transplantation : 3 to 6 months, 6 months to 2 years, more than 2 years after transplantation Secondary objectives : Assess the state of health Assess the knowledge Assess gestural know-how Assess the cognitive know-how Assess the behaviour adopted in reality by the patient Assess motivation psychosocial factors of : self-efficacy and inefficiency representation of obstacles, disadvantages of treatment sense of control over their health feeling of being supported by health professionals, by his close representation of his responsibility to take care of his health, to follow his treatment, to be active about his treatment

This study will examine bacteria and toxins in the mouth, lung and digestive system that may be the cause of various diseases or symptoms. H. pylori is a bacterium that produces various toxins that may contribute to lung problems. This study will examine specimens collected from the mouth, teeth, lung, digestive tract and blood to measure H. pylori and its toxins and their effects on cells. People 18 years of age and older with or without gastrointestinal disease may be eligible for this study. These include people without a history of lung disease as well as patients with any of the following: lymphangioleiomyomatosis, asthma, sarcoidosis, other chronic or genetic lung disease (e.g., chronic obstructive pulmonary disease, cystic fibrosis or eosinophilic granuloma). Participants may undergo the following tests: Blood and urine tests, chest x-ray. Measurement of arterial blood gases: A small needle is placed in an artery in the forearm to collect arterial blood. Lung function tests: Subjects breathe deeply and occasionally hold their breath. They may also receive a medication that expands the airways. Fiberoptic bronchoscopy with lavage and bronchial brushing: The subject's mouth and throat are numbed with lidocaine; a sedative may be given for comfort. A thin flexible tube called a bronchoscope is advanced through the nose or mouth into the lung airways to examine the airways. Saline (salt water) is then injected through the bronchoscope into the air passage and then removed by gentle suction. Next, a small brush is passed through the bronchoscope and an area of the airway is brushed to collect some cells for examination. Mouth rinsing or teeth brushing to collect cells. Endoscopy: A small needle and catheter (thin plastic tube) are placed into an arm vein to administer fluids and medications through the vein. A sedative may be given. The throat is numbed with lidocaine and a thin flexible tube called an endoscope is inserted through the mouth and down the esophagus into the stomach and upper part of the small intestine to examine those areas.

The primary objective of this registry study is to assess the durability of sustained virologic response (SVR) and clinical progression or regression of liver disease including the incidence of hepatocellular carcinoma following SVR in participants with cirrhosis after treatment with a sofosbuvir-based regimen for HCV infection.

The purpose of this study is to validate FibroScan and FibroSURE™ as equal or superior alternatives to liver biopsy for the monitoring and detection of methotrexate-induced hepatic fibrosis and cirrhosis in patients with moderate-to-severe psoriasis.

A post-treatment follow-up observational study for liver disease subjects with or without liver cirrhosis after receiving emricasan or placebo. Subjects must have been enrolled in a prior IDN-6556 study to be eligible.

The aim is to evaluate the impact of a 3-week lasting residential rehabilitation program for patients with cystic fibrosis on their nutritional status measured as BMI and body composition and pulmonary function.

The prevalence of chronic hepatopathies is high in jail. However, the medical care of these hepatopathies is few developed. This study is an observational, an epidemiologic (screening and prevalence of fibrosing hepatopathies) and an evaluating study for a better taking care of these hepatopathies in jail. The aims of the study will be to evaluate the diagnostic performance of the FibroMeter score in the screening of the hepatic fibrosis in persons with multiple risk factors for liver fibrosis (alcoholism, intravenous drug users, tattoo, and virological status) with FibroScan® as gold standard; to evaluate the feasibility of these different screening tools for chronic hepatopathies in jail and to evaluate the prevalence of the fibrosing hepatopathies with clinically significant fibrosis and theirs risk factors, alcohol and hepatitis B and hepatitis C viruses in population from Angers jail.
