Filter by:INTRODUCTION: Asthma is a disease characterized by inflammation of the airway and secondary contraction of smooth muscle. Treatment for the crisis consist in the use of local and / or systemic bronchodilators and anti-inflammatories, and it has been shown that mechanical ventilation to the airway through non-invasive positive pressure ventilation (NIPPV) decreases bronchial hyperreactivity and contractility of smooth muscle. OBJECTIVES: To assess the effect of nocturnal NIPPV on local inflammation, systemic inflammation and the state of hypersensitivity in patients with asthma attack. MATERIALS AND METHODS: We will include patients with severe asthma attacks requiring hospitalization, without indication for acute NIPPV, and will be randomized to receive NIPPV with an spontaneous (S) bilevel or continuous positive airway pressure (CPAP, control group), all patients will receive standard treatment; gasometric exchange, local inflammation (FEV1 and Exhaled fraction of nitric oxide), systemic inflammation (C reactive protein, IL-4, IL-5, IL-13 and IL-17 in peripheral blood) and the hypersensitivity state (eosinophilia and IgE) between both groups will be compared after 4 days of treatment.
This study aims to assess the feasibility of capturing data on exhaled breath compounds during an acute asthma exacerbation. In addition to assessing the feasibility of such a study the investigators will collect data on exploratory outcomes including the ability of breath biomarkers to distinguish between controlled and exacerbated states and their ability to differentiate between triggers of exacerbation.
