Active clinical trials for "Fibrosis"

Surgery on cirrhotic patients represents a clinical challenge but intervening before these patients develop complications can prolong the likelihood of these patients making it to transplant for those transplant-eligible candidates. There is no literature on survival to transplant afforded by surgery nor 90 day and 1-year outcomes after any surgical procedures on this population. The investigator's aim is to study the principal investigator's single surgical center experience at a tertiary hospital with the largest referral center in the area for liver transplant candidates. The investigators hypothesize, that although the risk is high for patients undergoing surgery it is much lower than historically reported, may make more patients eligible for transplant and prevent complications that may lead to death for the transplant eligible, and may reveal associations that can lead to good outcomes in this high-risk population.

The aim of this study is to compare pulmonary function, respiratory muscle strength, exercise capacity and peripheral muscle strength of patients with CF, PCD and healthy childrens.

Recently, the investigators described a new mucoid phenotype of Staphylococcus aureus cultured from the airways of cystic fibrosis (CF) patients.In this observational study, the investigators plan to determine the prevalence of mucoid S. aureus in respiratory specimens of CF patients and a possible impact of mucoid S. aureus on lung disease severity.

The aim of this pilot study is to demonstrate the feasibility of viral biomolecular diagnosis in sputum compared to nasopharyngeal swab in cystic fibrosis acute respiratory infection.

The main objective of the project "MucoFong" (19021906 national french program n which Vaincre La Mucoviscidose participated: N82006/ 351) was to determine the fungi present the respiratory tract of CF patients responsible for either colonization or authentic infectious diseases. The Mucofong data allowed the team to provide for the 1st time national French guidelines for the management of CF sputum mycological analysis (MucoMicrobes work group coordinated by Prof. Plésiat published in 2015 in the REMIC book). Nevertheless, the team has a comprehensive database that it still has to analyze beyond these initial results. The main goal today is to clarify the role of fungi in the lung function degradation of these patients by studying the overall risk and estimated impact of fungal colonization in our cohort.

The aim of our study is to validate the non-invasive model which was constructed by our previous study for evaluating liver fibrosis or cirrhosis caused by hepatitis B virus in mainland China and to find a therapeutic regimen to reverse liver fibrosis and cirrhosis.

The overall objective of this study is to determine the impact early nutritional and respiratory indices have on early CF lung disease. This knowledge will guide clinical management of infants with CF, who are now primarily diagnosed through newborn screening.

The purpose of this research is to learn more about the heart and blood vessels in the lungs of people with cystic fibrosis (CF). This study will include approximately 36 children and adults with CF and 12 children and adults without CF. The study will involve one magnetic resonance imaging (MRI) . The research also includes blood samples to look at inflammation and lung tests called spirometry and Lung Clearance Index (LCI) determined by Multiple Breath Washout test. For the CF subjects, enrollment will be timed to coincide with routine scheduled computerized tomography (CT) or the CF subject may choose to have a CT for research purposes. The MRI will be compared to CT images of the lungs. The goal is to develop better imaging that does not use radiation.

This study is designed to evaluate the risk of cataracts (lens opacities) and describe the best corrected distance vision (with glasses/contacts for those who wear them) of pediatric patients with Cystic Fibrosis who are 11 years of age or younger at the time of ivacaftor treatment initiation and are receiving or planning to receive commercially-available ivacaftor in the US.

Pulmonary arterial hypertension (PAH) is a condition characterized by an increased pulmonary vascular resistance that can lead to right heart failure and death. Several diseases are known etiologies of PAH including scleroderma and cirrhosis. The presence of PAH in the context of systemic sclerosis or cirrhosis has a dramatic impact on prognosis and survival of the connective tissue or liver disease. Despite advances in the diagnosis of PAH, echocardiography remains a necessary test for screening PAH in patients with scleroderma or cirrhosis. However, echocardiography is less than ideal for diagnosing PAH and predicting treatment response. Thus, there is a pressing need to identify methodologies that can accurately and non-invasively recognize the presence of PAH in patients with scleroderma and cirrhosis. Hypothesis: To measure endothelial function and exhaled gases in patients with scleroderma and cirrhosis. To assess whether they correlate with the presence or the development of PAH. The degree of local (forearm) capillary vasodilation during treprostinil iontophoresis identifies patients who will develop PAH and in those already diagnosed PAH predicts response to PAH-specific therapies.
