SOLIS, Marco et al. Evaluación del uso de corticoides inhalados en altas dosis para el tratamiento de crisis asmática. Rev. am. med. respir. [online]. 2016, vol.16, n.1, pp.4-10. ISSN 1852-236X.

Introduction: Asthma is a heterogeneous disease characterized by chronic inflammation of the airways. Its more common respiratory symptoms such as wheezing, breathlessness, chest tightness and cough vary in time and intensity, in addition to displaying variable airflow limitation. Asthma affects 1 to 18% of the world population. Evidence suggests that inhaled corticosteroids may show early therapeutic effects (<3 hours). This quick response would be linked to a local effect (vessel constriction of the airway mucosa) due to the potentiation of the adrenergic effect that modifies the postsynaptic receptors. Materials and methods: A prospective, randomized, analytical and experimental longitudinal cohort study in patients with acute asthma treated at the emergency services of the Respiratory Rehabilitation Hospital Maria Ferrer, Buenos Aires. Results: A total of 71 patients were evaluated over a period of 10 months who had agreed to participate in the study by signing an informed consent. Both the study and the control groups had a 63% significant response (FEV₁> 60%) within 30 minutes of starting treatment (p = 0.72). At the end of the observation (180 minutes), three patients of the control group (Salbutamol + ipratropium bromide) did not achieve the objective of FEV1> 60% compared to 2 patients in the study group treated with high-dose inhaled corticosteroids (P group: 0.97). Conclusion: Currently the use of high-dose inhaled corticosteroids in asthma attack is a therapeutic option for patients with moderate to severe crisis. The results of our study do not provide significant evidence in support of the use of this medication to reduce the incidence of hospitalizations or improve the lung function.
