Filter by:The main goal of this study is to prevent liver allograft infection with Hepatitis C virus in hepatitis C positive patients undergoing liver transplantation. The hypothesis is that patients who receive ribavirin immediately before transplant and intravenous interferon alfa 2b during the anhepatic phase(while the liver is removed)will have sustained virologic response post liver transplant.
The primary objective of this study is to determine if quantitative Dynamic contrast-enhanced magnetic resonance (DCE MR) perfusion imaging accurately quantifies right and left pulmonary artery blood flow as compared with phase contrast flow velocity mapping (PC), the current gold standard of flow volume measurements.
Goal: The primary goal of this study is to longitudinally investigate, in head and neck cancer (HNC) patients, the potential fibrosis-lymphedema continuum. Specifically, we will examine the development, patterns, progression, and prevalence of late-effect fibrosis and/or lymphedema, explore potential biological correlatives including pro-inflammatory cytokines and genetic polymorphisms, and evaluate the relationship among late-effect fibrosis and/or lymphedema and select psychosocial stressors that potentially interact with cytokine pathways. H: A minimum of 20 percent of HNC patients will experience late-effect fibrosis and/or lymphedema. H: We will be able to differentiate characteristics patterns of the development of late-effect fibrosis and/or lymphedema. H: We will be able to differentiate patterns of symptoms associated with late-effect fibrosis and/or lymphedema. H: We will be able to differentiate patterns of inflammatory response and the development of late-effect fibrosis and/or lymphedema. H: Select polymorphisms will increase the likelihood of development of late-effect fibrosis and/or lymphedema. H: Incidence and severity of late-effect fibrosis and/or lymphedema will correlate with total dose of radiation to involved anatomical site. H: HNC patients with fibrosis and/or lymphedema experience greater levels of depression and social withdrawal than those without these conditions.
The purpose of this study is to evaluate the safety and tolerability of denufosol 60 mg TID in pediatric CF patients 2 to 4 years of age
The investigators research question is whether or not yoga effectively alleviates symptoms of pain, sleep disturbance, anxiety and depression in children with cystic fibrosis. If yoga does prove to be effective, the investigators will educate our CF population about the benefits they may experience if they choose to incorporate yoga into their CF therapy. The investigators will also go on to do further research of other complementary alternative medicine therapies. This is a pre/post-test study with 20 subjects. The subjects will serve as their own controls. Each subject will participate in six yoga sessions over a ten week period. Subjects' symptoms will be evaluated with the use of questionnaires. The investigators will also test cortisol levels on weeks -2, -1, 1, 6, 7, 8. Cortisol is a hormone that is affected by stress. Testing of cortisol throughout the study will help us determine the subjects' stress level throughout the study.
Patients with cystic fibrosis (CF) suffer from chronic infections of the lower respiratory tract that can be caused by one or multiple bacteria, including Pseudomonas aeruginosa, which has been particularly problematic to eradicate and been implicated as the major cause of morbidity and mortality in CF patients. Aerosol delivery of antibiotics directly to the lung increases the local concentrations of antibiotic at the site of infection resulting in improved antimicrobial effects compared to systemic administration. Decreased efficacy, intolerance and high treatment burden with currently available therapies indicate a need for additional therapies. MP-376 (Aeroquin™) is a novel formulation of the fluoroquinolone levofloxacin that has been optimized for aerosol delivery. Preclinical and clinical studies conducted to date show that aerosol doses of MP-376 are safe and well tolerated, exert an antimicrobial effect, improve lung function and reduce the need for other anti-pseudomonal antibiotics. High concentrations of levofloxacin in the lung delivered as MP-376 are active against CF pathogens including those with high minimum inhibitory concentration (MIC) levels to aminoglycosides such as tobramycin (TOBI®) and other inhaled antimicrobial agents. Inhaled MP-376 can be delivered rapidly and efficiently using a customized PARI investigational configuration of the eFlow® nebulizer system.
To date, there have been no formal clinical studies completed using tiotropium in CF patients. While there is a large body of evidence demonstrating the efficacy and safety of tiotropium in patients with Chronic Obstructive Pulmonary Disease (COPD), relatively little is known about its efficacy and safety in patients with a diagnosis of cystic fibrosis. Therefore, Boehringer Ingelheim proposed to profile the long acting anticholinergic tiotropium and to generate adequate clinical data for use as a bronchodilator in paediatric and adult CF. The phase III trial (205.438) is a part of the approved Paediatric Investigation Plan (PIP) agreed for Spiriva® Respimat® in Cystic Fibrosis.
Malnutrition, including muscle wasting commonly occurs in children with cystic fibrosis (CF), negatively influencing their quality of life and survival. At the time of a diagnosis of CF, severe protein deficits can already be present. It is important to get CF children fed adequately to prevent that their condition becomes worse or that recovery takes longer. Oral supplementation trials showed that gains in lean body mass are difficult to achieve in CF unless specific metabolic abnormalities are targeted. However, the specific needs for certain food components are not clear yet in children that are ill. Therefore, more information is necessary on the need for protein and certain amino acids in children with CF. Previous studies support the concept of essential amino acids (EAA) as an anabolic stimulus in the young and elderly and in insulin resistant states. Until yet no information is present on the anabolic effects of EAA in CF. It is therefore our hypothesis that a high-leucine essential amino acids mixture specifically designed to stimulate protein anabolism will target the metabolic alterations of pediatric subjects with CF. In the present proposal, the acute metabolic effects of this high leucine essential amino acids mixture will be examined in pediatric subjects with CF and compared to that of a regular balanced total mixture of essential and non-essential amino acids. The principal endpoints will be the extent of stimulation of whole body protein synthesis as this is the principal mechanism by which either amino acid or protein intake causes muscle anabolism, and the reduction in endogenous protein breakdown. Both endpoints will be assessed by isotope methodology which is thought to be the reference method.
The aim of this trial is to offer continuation of BIBF 1120 treatment for patients with Idiopathic Pulmonary Fibrosis (IPF) who have completed a prior clinical trial with that drug. The primary objective will be to establish the long term tolerability and safety profile of BIBF 1120 in Idiopathic Pulmonary Fibrosis (IPF). As a secondary objective the effects of long term treatment with BIBF 1120 on survival as well as safety and efficacy parameters will be investigated in an open-label, not randomized, un-controlled design.
When a patient with glaucoma who has a pressure that is too high and causing damage to their vision, despite receiving the maximum amount of medication that can be tolerated, the decision is made to have glaucoma surgery. Trabeculectomy is the most common form of glaucoma surgery used to treat open angle glaucoma. During trabeculectomy, an opening is created in the eye and partially covered with a flap of tissue. This new opening allows fluid to drain out of the eye bypassing the clogged drainage channels that are malfunctioning in patients with glaucoma. Studies have found that trabeculectomy significantly reduces vision loss and lowers eye pressure. However, many people need another trabeculectomy or other glaucoma surgery because the surgery may fail either early or much later because the body closes the drain created by the surgeon. The surgery is also less likely to work in patients with darker pigmentation, children who have congenital glaucoma, people with difficult to control glaucoma with new blood vessels growing on the iris, diabetes or persons with prior eye surgery. As a result, the investigators need to find ways to improve the longterm survival of trabeculectomy surgery in all patients.
