Active clinical trials for "Fibrosis"

Study of Urinary Predictors of Exacerbations by Biomarkers in Cystic Fibrosis

According to the U.S. CF Foundation Patient Registry, more than 25% of children and 40% of adults were treated with intravenous (IV) antibiotics for flares of lung disease in 2016. Medication for these flares is often delivered through a peripherally inserted central catheter (PICC). Case series have identified important complications of PICCs in CF patients such as blood clots and infection. The frequency of PICC-associated blood clots in CF patients ranges from 2 to 8%. Catheter-related complications may interfere with completion of therapy and lead to repeated procedures and other complex medical treatments. In some cases PICC complications may discourage patients from accepting future courses of IV antibiotics. Therefore, it is very important to identify patient- and device-related factors that are linked with more frequent complications and to figure out ways to reduce these risks. Proposed risk factors fall into several broad categories. First are catheter-related factors; second are patient factors; and third are catheter-management factors. To date, no multicenter trial has carefully studied PICC complications in a large group of adult and pediatric CF patients from the time each catheter is placed to when it is removed. The main purpose of this study is to see whether the investigators can identify important factors in each of the three categories (patient, catheter, and catheter management) that are linked to various complications.

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 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.

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.

As more and more patients with cystic fibrosis (CF) become parents, we have studied parenting concerns in this serious chronic disease in a first study (MucoPar) which is ongoing. The current study (MucoKids) is an extension of the previous MucoPar study and aims to explore and collect the perceptions, expectations and needs of children whose one parent has CF. This will be done in the context of individual interviews or in several small groups of children led by a psychologist who will encourage them to develop what constitutes to be the child of somebody with CF. The collected information should make it possible to develop and propose adapted medico-psycho-social interventions, if necessary, in connection with patient associations.

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.

To evaluate the diagnostic performance of two-dimensional shear-wave elastography (SWE) for staging hepatic fibrosis in the background liver parenchyma in patients with liver tumors before hepatic resection, using resected tissue pathology as a reference standard.

The aim of this study is to assess prospectively the critical period prior to the development of Acute-on-Chronic Liver Failure (ACLF) (1), to uncover mechanistic and pathophysiological processes associated with the development and clinical course of ACLF (2) and to identify the precipitating events of ACLF (3).
