Filter by:This prospective study focuses on the interest of the echocardiography for cirrhotic patients, who present acute kidney injury corresponding to the criteria of hepatorenal syndrome. This echocardiography will be done before the volemic expansion and the final diagnostic of hepatorenal syndrome or prerenal azotemia. The primary endpoint is to describe the hemodynamic characteristics of this population at the time of acute kidney injury and their association with diagnostic of hepatorenal syndrome or prerenal azotemia. Patients with elevated filling pressure, predicting poor outcome of volemic expansion will be excluded of the study after the echocardiography and will not undergo volemic expansion but appropriate management.
Transition from tacrolimus based triple therapy with Mycophenolate Mofetil (MMF) and steroids in stable renal transplant patients to low intensity tacrolimus, everolimus and prednisone will be associated with improvement in Glomular Filtration Rate (GFR) and allograft fibrosis.
Idiopathic pulmonary fibrosis (IPF) is a disease of unknown cause in which areas of normal lung tissue are replaced by scars. As a result it becomes harder for the lungs to extract oxygen from the air. IPF is commonly progressive, and around 50% of patients diagnosed with the disease die after approximately 3 years. The most common, troublesome symptoms of IPF are breathlessness on exertion, and cough. No drug treatments have been unequivocally shown to improve the death rate, or to significantly impact upon symptoms, in IPF. In recent years it has been recognised that cough can be caused by small amounts of liquid coming up from the stomach and "going down the wrong way" into the lungs, a process commonly known as "reflux". As liquid in the stomach is usually acidic, patients' lungs may repeatedly be exposed to small amounts of acid. Reflux is unusually common in IPF and could potentially contribute to the debilitating cough found with the disease. However there are many potential causes for cough in IPF. Stomach acid can be efficiently "switched off" by drugs called "proton pump inhibitors", one of which is called omeprazole. If reflux of stomach acid does contribute to cough in IPF, omeprazole might be expected to reduce cough. The purpose of this study is therefore to test whether omeprazole does reduce cough in patients with IPF. Sixty patients with IPF will be randomly allocated to have 3 months of omeprazole or a placebo. Neither the patient nor the doctor will be aware which treatment has been given, ie this is a randomised "double-blind", placebo--controlled trial. Patients' cough frequency will be measured before and after treatment and the change in cough frequency compared in those receiving omeprazole and those receiving placebo. Change in cough frequency is the main thing we aim to compare, but a range of other measurements will be assessed such as the numbers of patients eligible to take part, agreeing to randomisation and providing outcome data, patients' lung function, symptom scores, the amount of reflux, and the amount of inflammation in the lungs.
With the use of Non invasive ventilation the patients with cystic fibrosis will have better lung function (FEV1).
This is a multi-centered, randomized, controlled study to assess the efficacy, indications and adverse reactions of combined administration of nebulized amikacin in patients with acute exacerbation of non-cystic fibrosis bronchiectasis and to evaluate whether inhaled antibiotics are more likely to cause bacterial resistance.
The purpose of this study is to determine if abatacept (Orencia) is effective in patients with primary biliary cirrhosis who do not respond adequately to standard treatment with ursodeoxycholic acid (UDCA, Urso, Ursodiol, Actigall).
The purpose of this study is to determine if zinc therapy: (1) strengthens your intestine's defensive barrier preventing damaging substances from reaching your liver, (2) decreases liver injury (inflammation, oxidative stress, cell death) and scarring, and (3) improves your liver-related health. Based on our preliminary animal data and other published reports, we expect zinc therapy to achieve all of these goals. Zinc is affordable, available over the counter or by prescription, and has an excellent safety profile. Positive results from this study will show that zinc is a significant therapy for millions of Americans with alcoholic liver disease.
The objective of this study was to evaluate the safety and efficacy of VX-661in combination with ivacaftor in participants with cystic fibrosis (CF) who are homozygous for F508del cystic fibrosis transmembrane conductance regulator (CFTR) mutation
This is a clinical study to characterise the lung function, airway morphometry, pharyngometry and inhalation profiles in patients with mild to severe Idiopathic Pulmonary Fibrosis (IPF) over a period of up to 6 months. Inhalation profiles will be recorded from patients with IPF as they inhale during tidal breathing, and following two sets of instructions (maximal effort and 'long, steady and deep' inhalation), across a range of airflow resistances that reflect those of typical inhalers used to deliver medication to the lungs. Mouth and throat dimensions will be measured using an acoustic reflectance Pharyngometer. Measurements of lung function will be made using conventional sprirometry, plethysmography and diffusion, whilst Low Dose High Resolution Computed Tomography (HRCT) will be used to scan the airways at two lung volumes; functional residual capacity (FRC) and total lung capacity (TLC). Data from HRCT will be used to reconstruct airway morphometry, and model inhaled particle deposition within the lung. Overall, the study allows a further understanding of the IPF patient population, using the data to assist in the development of new inhaled products for this disease. Following up the patients with additional HRCT scans at 3 and 6 months will enable the sensitivity of CT based criteria of disease progression to be compared with lung function criteria. No investigational product will be used in this study.
Cystic fibrosis (CF) has many health consequences. A reduction in the ability to perform exercise in patients with CF is related to greater death rates, steeper decline in lung function, and more frequent lung infections. However, the physiological mechanisms for this reduced exercise capacity are unknown. The investigators laboratory recently published the first evidence of systemic vascular dysfunction in patients with CF. Therefore, it is reasonable to suspect that the blood vessels are involved with exercise intolerance in CF. This study will look at how 1) blood flow and 2) artery function contribute to exercise capacity in CF.
