Factores que determinan el mal pronóstico y la exacerbación del asma en ni？os que asisten a consulta de alergología pediátrica

asthma is one of the diseases with a greater impact on pediatric practice. this descriptive, cross-sectional study was undertaken to identify those factors determining the exacerbation and poor prognosis of bronchial asthma in children. forty five patients with diagnosis of bronchial asthma were studied. the crises were developed at home in 76 % and at school in 24 % of the children. triggering causes of acute crises of bronchial asthma were: exercise (73 %), respiratory infections (57 %), and rhinitis (55 %). the factors of poor prognosis most frequently found were: rhinorrhea without cold (60 %), male sex (51%), three or more episodes of wheezes in previous months (42 %), and asthma in parents (37 %). the presence of exacerbations and the criteria of poor prognosis influence on the control and quality of life of the asthmatic children, and they should be detected at the primary care level.
