Brief Summary
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.

Study Arms (2)
NIPPV
EXPERIMENTALPatients will receive NIPPV with an S bilevel device during 4 nights, the equipment will be placed ad libitum, a 12 cmH2O inspiratory pressure and a 4 cmH2O expiratory pressure will be administered through a nasal mask. CRP, FEV1, exhaled fraction of nitric oxide, IL-4, IL-5, IL-13, IL-17, IgE, cell count will be measured before and after intervention.
CPAP
SHAM COMPARATORPatients will receive a 4 cmH2O continuous positive airway pressure device during 4 nights; this is the minimum pressure necessary to avoid death space with no effect on minute ventilation. The equipment will be placed ad libitum. Pressure will be administered through a nasal mask. CRP, FEV1, exhaled fraction of nitric oxide, IL-4, IL-5, IL-13, IL-17, IgE, cell count will be measured before and after sham intervention.
