Filter by:At the Department of Infectious Diseases, Aarhus University Hospital, continuous infusion with piperacillin/tazobactam for a period of 2 weeks, has been used for several years in patients with cystic fibrosis, suffering from acute pulmonary exacerbations (APE). It is an outpatient treatment. To assess the efficacy and quality of the treatment, a blood test every 3rd day is taken to determine the concentration of Piperacillin in blood-plasma.
This study will test the hypothesis that treatment with laparoscopic anti-reflux surgery in subjects with idiopathic pulmonary fibrosis (IPF) and abnormal gastroesophageal reflux (GER) will slow the decline of forced vital capacity (FVC) over 48 weeks.
This is an 6 month multi-centre, prospective, randomized, placebo controlled, double blind clinical trial followed by conversion of each arm to active nintedanib for an additional 6 months comparing the effect of nintedanib 150mg bis in die (BID twice daily) on the progression of IPF measured by using High Resolution Computerized Tomography(HRCT), lung function, functional component (6MWT), biomarkers, and PRO component (PROs) with continued treatment and assessments for up to 18 months.
Most Cystic fibrosis (CF) patients now commonly live well into adulthood, this means they are progressively accumulating damage to the insulin-secreting cells inside their pancreas. This explains why most adult patients have some degree of abnormal sugar regulation & rates of diabetes rise significantly with age. CF related diabetes is categorically different from other types of diabetes & its development is serious as it heralds a faster decline in lung function & a reduced life expectancy. The hallmark of abnormal sugar handling in CF is high glucose levels after meals as the damaged pancreas responds abnormally slowly. Over 70% of the initial response of a healthy pancreas is induced, not by glucose alone, but by hormones released from the bowel known as incretins. We want to establish whether incretins are important in blood sugar handling in CF as specific drugs that enhance their effect are now available. The study hypothesis is that the incretin system will function normally in patients with Cystic Fibrosis. To show this we will measure how much insulin secretion is dependant on incretin hormones in CF patients by comparing levels after a sugary drink test and then an intravenous glucose drip test (run at a rate that mimics the blood sugar levels obtained during the first test to make it a fair comparison ) - as incretins will only be produced in the first test when the sugar passes through the bowel any extra insulin produced will be due to these hormones. To detect resistance to the incretin hormones we will separately measure responses to direct infusions of the hormones themselves. We will explore which components of meals cause incretin hormone release from the bowel wall by measuring blood levels after different types of meals are consumed. Finally we will measure levels of the enzyme that breaks down the incretin hormones (DPP-4) to know if they are deactivated more quickly in people with CF. By describing the incretin system in CF we will considerably improve our understanding of this important condition as well as potentially highlighting new ways to treat it.
The purpose of this study is to test the hypothesis that early viral infections alter the bacterial flora and inflammatory profile in the airway and accelerate progression of pulmonary disease in infants with cystic fibrosis.
Recent research studies have suggested that proteins called antibodies that are produced by the immune system might be involved in the lung damage of idiopathic pulmonary fibrosis (IPF). Antibodies produced by the immune system normal help to fight infections by attacking bacteria and viruses without harming our own tissues. In patients with IPF, there is evidence that certain antibodies (called autoantibodies) attack the lung and contributes to the injury and scarring that occurs in IPF. Our recent studies have found that many IPF patients appear to have excessive autoantibody levels in blood and lungs that might make their disease worse. Rituximab is a medication approved by the Food and Drug Administration (FDA) for the treatment of autoantibody diseases such as rheumatoid arthritis. Rituximab works by destroying B cells, a type of white blood cell, called a B-lymphocyte, which produce autoantibodies. In this research study, rituximab will be given into a vein to reduce the autoantibody levels that we believe might be contributing to the lung damage in IPF. This study is being conducted to determine if rituximab provides beneficial effects for IPF patients by decreasing further lung injury.
The aim of our prospective study is to construct and validate a non-invasive model consisting biochemical markers, FibroScan, and radiological parameters for evaluating liver fibrosis caused by hepatitis B virus in mainland China.
Cystic fibrosis (CF) is a complex systemic disease that mainly involves the respiratory and gastrointestinal (GI) tracts. The polymicrobial community composition of respiratory and GI tracts is influenced by both genetic and environmental factors. Children with CF may harbor an abnormal intestinal microflora, because of altered Cystic fibrosis transmembrane conductance regulator (CFTR) function and heavy drug load (antibiotics, pancreatic enzymes and acid suppressors). The investigators previously demonstrated that intestinal inflammation is highly frequent in CF children, being a major feature of intestinal involvement. In addition, specific probiotics significantly improved airway and GI inflammation in a preliminary trial. The aim of the study is to characterize intestinal and respiratory microflora in CF patients and to investigate the effects of daily Lactobacillus GG (LGG) supplementation on both GI and airway microflora and the eventual relationship between probiotic assumption and clinical and inflammation markers. The aim is to study the effect of microflora modification on intestinal and extraintestinal inflammation to eventually improve the quality of life of CF patients, who often suffer from intestinal and respiratory progressive disease, through a non invasive intervention consisting in the supplementation of probiotic bacteria.
To enhance understanding of supplemental oxygen—its utility in and adoption by patients with pulmonary fibrosis—by examining how patients perceive it and by determining how perceptions and patient-centered outcome measures change from before to after supplemental oxygen is prescribed.
Cirrhosis is associated with a reduction in muscle mass and exercise capacity. This has an impact on morbidity and mortality. Regular aerobic exercise training is a proven effective therapy to improve exercise capacity in healthy and clinical populations. The effect of this training has not yet been evaluated in the decompensated cirrhosis patient population. The safety of this intervention also requires further study. Using a randomized controlled design, the investigators aim to determine the safety and efficacy of eight weeks of aerobic exercise training on aerobic capacity, functional performance, and muscle mass in decompensated cirrhosis patients.
