Filter by:Myocardial fibrosis is recognized as the pathologic entity of extracellular matrix remodeling. Diffuse, reactive fibrosis is increasingly recognized in a variety of conditions despite the absence of ischemia. Regardless of the etiology, fibrosis leads to increased myocardial stiffness thereby promoting cardiac dysfunction. This dysfunction may present clinically with symptoms of cardiac failure although this is often a subclinical disease. Various imaging modalities and collagen biomarkers have been used as surrogate markers to assess the presence, extent, and turnover of myocardial fibrosis. Techniques using echocardiography, cardiac magnetic resonance, and nuclear imaging have been developed to detect early features of systolic and diastolic left ventricular dysfunction and impaired contractile reserve. Further identification of diffuse reactive fibrosis may be possible with evolving cardiac magnetic resonance and molecular techniques. The goal of this protocol is to validate cardiac magnetic resonance imaging as a new tool for fibrosis quantification against histology as standard of reference.
Evolution of medical care for patients with cystic fibrosis appeared in recent years: prolongation of life expectancy with consequently increased comorbidities and the use of lung transplantation, systematic neonatal screening of new born since 2002, prescription of expensive new molecules or new presentation. This evolution justifies to realize an update of statistics of costs of care and to assess adherence to treatment
This is a pilot cross-sectional study of measured transcutaneous CO-oximetry in children with inflammatory and non-inflammatory conditions.
The purpose of this study To evaluate the safety and efficacy of PRI-724 administration in patients with cirrhosis due to hepatitis C by 12-month follow-up.
Liprotamase consists of 3 soluble, non-porcine digestive enzymes, lipase, protease, and amylase, combined in a fixed ratio. Liprotamase is stable in the stomach and can be formulated without enteric coating for administration either as a capsule or as a dosing solution dissolved in water or juice.
Ursodeoxycholic acid (UDCA) has been the only treatment for primary biliary cirrhosis (PBC) approved by US and European drug administrations. Long-term use of UDCA(13-15 mg/kg/day) in patients with PBC improves serum liver biochemistries and survival free of liver transplantation However, about 40% of patients do not respond to UDCA optimally as assessed by known criteria for biochemical response. Those patients represent the group in need for additional therapies, having increased risk of disease progression and decreased survival free of liver transplantation. Both lab research and some clinical studies suggest that fenofibrate could improve cholestasis in multiple ways including reduce of bile acid synthesis, increase of biliary secretion and anti-inflammation effect. Here we start a random, open and parallel clinical research to explore the effect of fenofibrate in the PBC treatment.
Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). A recent treatment option known as Orkambi, which combines the drugs lumacaftor and ivacaftor, may be used in patients with CF to help improve lung health. However, the effects of this combination therapy on dyspnea and exercise performance, a known predictor of survival in CF, are not clear. The investigators aim to understand the effects of Orkambi on these symptoms and to gain new insight into the potential health improvements in CF from using this treatment option.
Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with a high mortality. Health-related quality of life (HRQL) is impaired in patients with IPF. Little is known about the properties of recently developed HRQL questionnaires and about the longitudinal changes in HRQL, including factors with an impact on HRQL. Comorbidities have an impact on patients with IPF, but reports differ in incidence and prevalence. The impact of comorbidities on HRQL and disease progression has only been studied sparsely. Also, the association between biomarkers and disease progression need to be examined further.
With improved survival, the clinical spectrum of cystic fibrosis (CF), a complex multi systemic disease, continue to evolve. A major emerging complication is CF related diabetes (CFRD) which is occurring in 40-50% of adults. Patients who develop CFRD are at increase risk of morbidity and mortality and they are also facing an increased medical burden with insulin therapy, the only recommended treatment. Accelerated decline in weight and/or pulmonary function start 2 to 4 years before CFRD onset and this period is characterized by frequent Post-Prandial Glycemic (PPG) excursions. Higher PPG excursions are associated with lower pulmonary function and it predicts future CFRD risk. To the improved nutritional status, lung function and survival of patients, the nutritional approach for patients with CF focuses on high-energy high-fat diet and a pancreatic enzyme supplementation. However, such diet also contributes to increased PPG excursions. Based on the beneficial effects of nutrition therapy to improve PPG in other forms of pre-diabetes and diabetes, extending such benefits to patients with CF is important. The investigators aim to test the feasibility and the effectiveness of a viscous fiber supplement to reduce PPG in adult patients with CF. Using a randomized crossover design, the investigators will study the impact of two doses of a viscous fiber supplement as compared to a placebo.
The academic investigator - initiated trial will evaluate in a postapproval setting whether, and if yes, to what extent and variability, the treatment with lumacaftor in combination with ivacaftor reverses the p.Phe508del CFTR - mediated basic defect in p.Phe508del homozygous subjects with cystic fibrosis under real life conditions.
