Filter by:The Purpose of A Multicenter, Randomized, Double-blind, Placebo-controlled to Evaluate the Efficacy, Safety and Pharmacokinetics of N02RS1 600mg and 1,200mg per day in Patients With acute and acute exacerbation of chronic bronchitis for 7 days.
SPIROMICS I and SPIROMICS II are observational studies of Chronic Obstructive Pulmonary Disease (COPD). SPIROMICS I had two main aims: (1) To find groups of patients with COPD who share certain characteristics; (2) To find new ways of measuring whether or not COPD is getting worse and so provide new ways of testing whether a new treatment is working. SPIROMICS II has three primary aims. Aim 1 is to define the natural history of "Smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition. Aim 2 is to determine the radiographic precursor lesion(s) for emphysema, and identify the molecular phenotypes underlying airway disease and emphysema. Aim 3 is to advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response.
The main objective of the current trial is to investigate safety, tolerability and pharmacokinetics of BI 113608 in COPD patients with symptoms of chronic bronchitis.
A phase III multicenter randomized double blind clinical trial will be conducted. After obtaining written consent the infant will be randomized, during the first two weeks of life, to a study group to receive either 400 IU or 1,000 IU / day of vitamin D to the year of age. Baseline and all follow up visits (2, 6, and 12 months of life) will include anthropometric measurements and a questionnaire about health issues. A blood sample will be obtained at baseline for analysis of 25OH vitamin D, and at 6 and 12 months for analysis of 25 OH vitamin D, and calcium. Healthy term born infants of appropriate size for gestational age will be included. We will need to include 359 children in each group. The primary objective of the study is to decrease the proportion of infants with acute bronchitis during the first year of life by supplementation of 1,000 IU/day vitamin D. Secondary otcomes are: To check that the administration of 1,000 IU/day vitamin D decreases the proportion of infants with upper respiratory tract infections, the proportion of children under one year of age hospitalized for acute bronchiolitis, and the demand on the healthcare system due to respiratory infections and absences from work for parents and achieves a higher proportion of children with adequate blood levels 25 OH vitamin D.
Postoperative pain after cardiac surgery is a risk factor for postoperative complications. In cardiac surgery, pain is more intense during the first 48 hours and disturbs the patient's capacity of coughing, deep breathing, and early mobilisation. It may be responsible for respiratory complications such as bronchial or pulmonary infection, and may also delay the patient's rehabilitation and therefore prolong the duration of in-hospital stay. A previous pilot study performed in our department showed a sensible improvement of analgesia at movement and of rehabilitation with a continuous bilaterosternal infusion of local anaesthesia [Eljezi et al.. Reg Anesth Pain Med 2012; 37:166]. Such strategy shall be tested in a subpopulation of patients at risk for respiratory complication.
This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in December 2012. The purpose of this study is to make a event monitoring to see whether Tanreqing injection is safe and the characteristic and mechanism of anaphylactic reaction used Tanreqing injection in hospitals in China.
This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in January 2013. The purpose of this study is to make a event monitoring to see whether Reduning injection is safe and the characteristic and mechanism of anaphylactic reaction used Reduning injection in hospitals in China.
The general hypothesis is that delayed antibiotic treatment strategy present similar effectiveness, when compared with non-prescription of antibiotics or the prescription of antibiotics, in the non-complicated acute respiratory tract infections in pediatric patients.
The purpose of this research study is to examine the effects of two weeks of daily dosing of inhaled salt water mist (hypertonic saline - HS) on actual measurements of mucociliary and cough clearance in patients with the chronic bronchitis type of Chronic Obstructive Pulmonary Disease (COPD. Defective mucociliary clearance (MCC) is central to the development and/or worsening of several kinds of lung diseases, including COPD/chronic bronchitis (CB), cystic fibrosis (CF), and bronchiectasis. In each case, defective MCC leads to the development of lung infections and damage to the airways from ongoing inflammation caused by a person's inability to clear mucus from the lungs. The investigators' previous studies have shown that the administration of inhaled HS (hypertonic saline) not only acutely accelerates MCC in CF, but also that repetitive use "resets" the baseline rate of MCC within 2 weeks. It is likely that the sustained effect of HS on MCC was responsible for the ~60% reduction in the frequency of pulmonary disease exacerbations, reduced antibiotic use and improved lung function in a long-term study of HS in CF volunteers. As a result, HS has now become a standard therapy for CF lung disease and its success raises optimism that similar benefits might occur in patients with CB. In this study the investigators will use mildly radioactive particles, technetium bound to sulfur colloid, to measure and compare the sustained effects on mucus clearance of two weeks of daily dosing of 7% hypertonic saline versus a low salt control treatment for subjects with CB. We will also be collecting sputum and breath condensation to analyze for protein and inflammatory changes that might occur with exacerbations. Our long term goals are to improve our understanding of MCC in health and disease and to develop better therapies that support and/or restore MCC in patients with these diseases to reduce lung infections.
xTAG RPP assay is a PCR-based assay to detect the presence or absence of viral and bacterial DNA / RNA in clinical specimens (nasopharyngeal swabs). The objective of this study is to establish diagnostic accuracy of the xTAG RPP.
