Filter by:Many studies describe the relationship between microbiota alteration and the occurrence of metabolic, alcoholic or inflammatory liver diseases. Nevertheless, the modifications of microbiota during liver transplantation (LT) as well as its implication are poorly studied. Similarly, only the intestinal microbiota is studied in this context, and no data are available on the biliary microbiota, even if it is known that bile microbiota can interfere with hepatobiliary diseases. This study proposes a clinical and biological in-depth follow-up with multiple sampling of liver transplanted patients to study biliary and intestinal microbiota alterations along LT, as well as bile acids metabolism in corresponding fluids. Indeed, in recipient samples as saliva, blood, urine, and feces can be taken before LT, and surgeons can easily perform bile sampling during LT. In donors all samples can be taken during liver removal. This offers the opportunity to have a microbiotic landscape of individuals without liver disease (donor), and patients suffering from a chronic liver disease or a liver cancer before and after transplantation. Also, in Grenoble University hospital, in case of biliary anastomotic incongruence, a biliary stent is placed during LT in 60% of recipients. This stent is removed by endoscopic retrograde cholangiopancreatography (ERCP) within 6 months after LT, offering a second opportunity to obtain bile samples in transplanted patients, after the early post-LT period. Patients who do not require a biliary stent will also be included for the study of secondary objectives, as intestinal microbiota is very poorly characterized in liver transplanted patients too. A portion of the patients without biliary stent, may also develop an anastomotic biliary stricture requiring an ERCP. If this ERCP is realized within the follow-up period of the study, the patient will also be included in the primary objective of the study. These multiple and sequential samples will allow a complete analysis of microbiota changes in LT patients and aim to answer to 3 questions: 1. What are the modifications of intestinal and biliary microbiomes during LT? 2. What is the influence of bile acids' composition on intestinal and biliary microbiota? 3. What are the relationships between microbiome alterations and the emergence of LT complications?
The aim of this study is the data collection for patients with IPF and symptom matched controls to create a database of lung auscultation sounds and basic patient characteristics.
The purpose of this study is to validate the user interface of TOBI Podhaler by establishing that the product can support safe and effective use for the intended users
The study is a randomized, double-blind, placebo-controlled, study that will be conducted at multiple centers in subjects with Cystic Fibrosis (CF) who are either homozygous for the F508del mutation or heterozygous with at least copy of the F508del mutation.
The aims of this study are to determine whether neuromuscular stimulation (NMES) of the quadriceps muscle is acceptable to patients with Idiopathic Pulmonary Fibrosis (IPF) and staff and whether it can impact clinical and healthcare resource usage outcomes. .
Cytobacteriological examination of sputum and bacteriological sampling in the middle meatus.
The purpose of this study is to determine the feasibility of a home meal delivery program for patients with cirrhosis and ascites and to determine the effectiveness of a salt-restricted (2 gram sodium) meal delivery program in reducing the need for therapeutic paracenteses and/or all-cause re-admissions for these patients. Many patients with cirrhosis don't have enough nutrients in the body and are frail and these meals may help them maintain a good diet and lead to improved quality of life.
The aim of the study is to look for risk factors of developing osteoporosis in patients with cystic fibrosis. Blood cells called monocytes will be obtained from a blood sample. These monocytes will make possible to form another class of cells called osteoclasts in the laboratory. These latter cells are responsible for bone degradation and therefore promote the increase of bone fragility. The research will focus on the characterization of these cells to better understand their potential (low, medium or high) to increase bone fragility in patients with cystic fibrosis. Finally the action of CFTR modulators on these bone cells will be tested.
A manipulation and an integral part of the pharmaceutical practice, where, in addition to the supply of medicines and personalized products, they represent an alternative to the therapeutic schemes, manipulating drugs of almost all of them as therapeutic categories. One of the products and ursodeoxycholic acid, commercially known as Ursacol, a bile acid physiologically present in human bile, approved by Agência Nacional de Vigilância Sanitária (ANVISA), among several indications, for the treatment of the symptomatic form of primary biliary cholangitis, autoimmune etiology and predominant incidence in female. This is a prospective, cross-over, interventional and open-label study, where patients attending the inclusion and exclusion criteria are attended by the Instituto Central do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (ICHC-FMUSP) Pharmacy Division in the Pharmaceutical Care sector. As patient information as well as the prescribed drugs, compiled by a data collection instrument from the ICHC-FMUSP Pharmacy Division and a semi-structured questionnaire.
An open label non-randomized study enrolling up to 20 healthy participants and up to 30 participants with cystic fibrosis to establish a healthy versus disease comparison. Each participant will receive a mixture of inert gas (perfluoropropane (PFP)) in a ratio of 79% PFP to 21% oxygen as a contrast agent to enhance visualization of the airway and alveolar spaces using magnetic resonance imaging of inert gas/oxygen mixtures. The study consists of a screening visit followed by up to 2 study visits.
