Filter by:We hypothesize that the miRNA expression in subjects with nasal polyps and Aspirin-exacerbated respiratory disease (AERD) differs from the miRNA expressed in subjects with nasal polyps but without Aspirin-exacerbated respiratory disease (AERD).
This is an observational study that proposes to collect clinical, physiological, cellular and molecular information in an attempt to identify a set of factors that may predict the risk for persistent lung disease in babies born prematurely.
The investigators are doing this research study to find out if giving a drug called prasugrel, which is used to prevent blood clots, can reduce reactions to aspirin in people with aspirin exacerbated respiratory disease (AERD), and to learn why taking aspirin every day can work as a treatment for people with AERD. People with AERD have symptoms of asthma, severe runny nose, polyps in the nose, and develop allergic reactions if they take medications like aspirin. People with AERD can be desensitized to aspirin in order to be able to safely use it daily, but the investigators do not know if prasugrel may prevent reactions to aspirin and provide a safer way for people with AERD to tolerate aspirin. The investigators also want to understand what is different about the cells and urine from subjects who have AERD, in comparison to subjects who have asthma but do not have AERD and subjects who have allergic rhinitis but do not have asthma. Lastly, the investigators want to understand how aspirin acts differently in subjects who have AERD, in comparison to subjects who have asthma but do not have AERD.
GSK1995057 is a fully human, single domain antibody directed against the TNFR1 receptor. The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of inhaled GSK1995057 in healthy subjects. The study will be in two parts. Part 1 is a single-dose escalating design of 5 sequential cohorts of healthy subjects. Part 2 is a single-dose, parallel group design comprising 2 groups of healthy subjects assessing the effect of GSK1995057 on lung inflammation following inhaled LPS challenge. Actual dose administered in Part 2 will be determined from emerging safety and PK data from Part 1 and Study TFR110951.
The purpose of this study is to determine whether FVH1, a DNA-based influenza vaccine, will be safe and generally well tolerated in healthy elderly adult volunteers and will result in greater immunogenicity when used to prime the immune response to a dose of a trivalent inactivated seasonal vaccine.
In Sickle cell disease children, sleep respiratory abnormalities are risk factors for vaso-occlusive complications, as well as cerebral vasculopathy. A 18 months follow-up children with sickle cell disease evaluating sleep respiratory problems frequency and etiology, as well as their influence on sickle cell disease complications.
The main objective of this study is to investigate the safety, pharmacokinetics (PK) and the relationship between PK and pharmacodynamics (Minimum Inhibitory Concentration [MIC] and Mutant Prevention Concentration [MPC]) of intravenous BAYQ3939 (400 mg BID and 400 mg TID) in hospitalized patients with bacterial pneumonia or secondary infection of chronic respiratory disease with severe disease or a poor response to other antimicrobials. In addition, the efficacy of the ciprofloxacin, in terms of clinical response and microbiological response, will be investigated, but as a secondary endpoint.
The present study aims to assess the natural immunity to specific microbial antigens in healthy subjects and in subjects with stable COPD aged between 45-75 years.
This study aims to evaluate simple tests of physical function in hospitalised patients with chronic obstructive pulmonary disease (COPD) and to assess whether they can predict future hospital readmission. The Short Physical Performance Battery (SPPB) is a simple test of standing balance, usual walking speed (4-metre gait speed) and ability to stand from a chair, which reflects global physical functioning and frailty. We hypothesise that the SPPB or 4-metre gait speed can predict future hospital readmissions.
Proprioceptive weighting changes may explain differences in postural control performance. In addition, the respiratory movement has a disturbing effect on postural balance. Postural balance seems to be impaired in individuals with respiratory disorders. Besides the essential role of respiration, the diaphragm may also play an important role in the control of the trunk and postural balance. Deficits in proprioception are found in a subgroup of patients with low back pain. In addition, disorders of respiration have been identified as strongly related to low back pain. The aim of the study is to clarify whether inspiratory muscle training has a positive effect on proprioceptive postural control in individuals with recurrent low back pain.
