Active clinical trials for "Fibrosis"

This is a multicenter prospective registry of IPF patients in South Korea. The Seoul National University Bundang Hospital is the coordination center for the Korean IPF Registry built by a collaboration of the Korean Interstitial Lung Diseases (ILD) Study Group.

In 2005, The University of Alabama at Birmingham established a NIDDK-funded, interdisciplinary center of excellence in PKD-related research, with specific emphasis on recessive PKD. In the previous Core Center award period, we developed a Core Resource to capture clinical and mutational data for ARPKD patients ("Core A: ARPKD Clinical and Genetic Resource", NCT00575705). However, studies in the last several years have demonstrated that ARPKD and other single gene disorders characterized by renal cystic disease and extra-renal phenotypes share numerous pathogenic features. In the current competitively- renewed Center, we have expanded this Core resource to include other hepato/renal fibrocystic diseases. Goals for the Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource are: - Clinical Database: • Expand our comprehensive Clinical Database to include information from all patients who meet the inclusion criteria for hepato/renal fibrocystic diseases. - Mutational Database: Test children with ARPKD and other hepato/renal fibrocystic disease to identify genetic mutations, establish a DNA bank for patients with hepato/renal fibrocystic diseases and develop a Mutational Database. This Database will be capable of linking clinical and mutational information via a unique identifier in a searchable format to facilitate genetic research (e.g. genotype-phenotype correlations, new disease gene studies, and modifier gene studies), translational studies, and clinical trials. 3- Tissue Resource: Much of the research that is performed on diseases of the kidney, including recessive genetic diseases, requires human tissue from both affected as well as non-affected (controls) individuals. In this Core Resource, we are establishing an independent tissue resource which would supply investigators throughout North America with samples of hepato/renal fibrocystic disease affected tissues for studies of these disorders. 4- Educational Resource: Expand our multi-media, web-based resource to provide a reliable up-to-date, and comprehensive informational resource for ARPKD and Hepato/Renal Diseases families, their physicians, and genetic counselors. All the information regarding participation in "Core A: The Hepato/Renal Fibrocystic Diseases Translational Resource" is available at: http://www.arpkdstudies.uab.edu/.

The goal of this study is to use the tissues from the explanted lungs in order to better study the cause of pulmonary fibrosis at a cellular level.

The etiology of pulmonary fibrosis is unknown. Analyses of blood, genomic DNA, and specimens procured by bronchoscopy, lung biopsy, lung transplantation, clinically-indicated extra-pulmonary biopsies, or post-mortem examination from individuals with this disorder may contribute to our understanding of the pathogenic mechanisms of pulmonary fibrosis. The purpose of this protocol is to procure and analyze blood, genomic DNA, and specimens by bronchoscopy, lung biopsy, lung transplantation, extra-pulmonary biopsies, or post-mortem examination from subjects with pulmonary fibrosis. In addition, blood, genomic DNA, clinically-indicated extra-pulmonary biopsies, as well as bronchoscopy and post-mortem examination specimens may be procured and analyzed from relatives of subjects with hereditary forms of pulmonary fibrosis; blood, genomic DNA, and bronchoscopy specimens may be procured from healthy research volunteers....

Most of the cystic fibrosis (CF) patients are or have been pulmonary colonized with bacteria such as Pseudomonas aeruginosa or Staphylococcus aureus. Aim of this study is to detect virulence factor neutralizing antibodies in the sera of the study population followed by B cell repertoire analyses to design B cell-derived neutralizing monoclonal antibodies. The functionality of neutralizing antibodies rests on inhibition of virulence factors by binding of crucial epitopes rather than merely the induction of opsonization. Focusing on patients with bacterial colonization/chronic infections or a history of an acute infection in the past, will increase the likelihood for identification of serum with neutralizing activity as in vivo antigen contact is a prerequisite for antibody development and maturation. Since virulence factors are essential for infection, dissemination and tissue damage, inhibition of these factors by developed neutralizing antibodies might contribute to a favorable outcome of life-threatening infections.

This is a single center patient registry of patients receiving a transjugular intrahepatic portosystemic shunt (TIPS) at Hannover Medical School. By collecting and analyzing clinical data as well as blood samples, the overall aim is to optimize TIPS therapy (e.g. specify selection criteria).

80% of patients with alcohol use disorders (AUD) present cognitive impairments, such as memory and executive functions. These disorders may have repercussions in addiction treatment by altering the patient's adherence to care. The level of impairment is dependent on the onset of addiction, and also the duration of abstinence. A complete neuropsychological evaluation is necessary to highlight cognitive impairments. In practice, the evaluation of these disorders by practitioners, is done with the help of tools of screening like the MoCa (Montreal cognitive assesment) and the BEARNI (Brief evaluation of alcohol related neuropsychological impairment). However, none of these tools have been evaluated in patients with alcoholic cirrhosis. Indeed, some studies have suggested that liver disorders including cirrhosis may be a factor aggravating cognitive disorders. The purpose of this study is to evaluate the ability of the BEARNI tool to detect alcohol-related cognitive problems in patients with alcohol-related cirrhosis.

Idiopathic pulmonary fibrosis (IPF) is the most common form of chronic idiopathic diffuse interstitial lung disease (DILD) in adults. It is a fibroproliferative, irreversible disease of unknown cause, usually progressive, occurring mainly from the age of 60 and limited to the lungs. IPF is a serious disease with a median survival rate at diagnosis of 3 years. The aim of the study is to set up a biocollection of serum from patients in a context of idiopathic DILD and a possible or confirmed diagnosis of common interstitial lung disease by chest CT. Patients will be recruited at the consultations of the Rennes Rare Lung Disease Competence Centre. These will be patients in stable condition or in acute exacerbation of IPF.

Cystic fibrosis (CF) is an autosomal recessive genetic disorder caused by mutations in the gene encoding CF transmembrane conductance regulator (CFTR), which is located at 7q31.2 and encodes 1480 amino acids. CFTR protein is responsible for regulating the transport of electrolytes and chloride across epithelial and mucus-producing cell membranes.

Background: Severe aortic valve stenosis (AS) is the commonest valve disease. Aortic valve replacement (AVR) is primarily indicated when symptoms occur and/or when there is a drop in left ventricular ejection fraction. However, irreversible myocardial damage, such as replacement fibrosis, leads to increased morbidity and mortality despite treatment. Improved patient selection and timely treatment is thus warranted. T1 mapping, a non-invasive method to quantify myocardial fibrosis by cardiac magnetic resonance (CMR), could be a marker to guide treatment. Aims: To investigate the change of myocardial fibrosis* in AS patients following AVR and if these changes are associated with disease and/or procedural characteristics. Methods: This is an observational clinical trial. Approximately 60 patients with severe AS planned to undergo AVR (either surgical or transcatheter) at Rigshospitalet, Denmark will be included. Participants will undergo CMR before surgery and at a 1-year follow-up. Other assessments include clinical evaluation and blood sampling. The primary end-point is change in T1 values after AVR. Hypotheses and perspectives: The investigators hypothesize that (1) myocardial fibrosis* will regress in patients undergoing AVR as a group, (2) the degree of myocardial fibrosis is positively correlated with the degree of symptoms, (3) the regression of myocardial fibrosis is greater in patients undergoing TAVR compared to SAVR, and (4) the regression of myocardial fibrosis is greater in patients with tricuspid aortic stenosis compared to bicuspid aortic stenosis. Ultimately, T1 mapping is a potential marker for improved patient selection for the timing of AVR. * Estimated by T1 mapping
