ABSTRACT

Asthma is a public health problem; in Mexico asthma is included among the ten causes of hospital and medical care. Exacerbations of asthma (asthma attacks or acute asthma) are episodes of progressive increase in shortness of breath, coughing, wheezing, tightness in the chest, or a combination of these symptoms. It has been identified airway infections, as the major etiology of exacerbations. Microbiological study of the sputum of the 90 patients included in this study was performed. The results showed that pathogenic microorganisms associated to asthma exacerbations were isolated in almost 50% of the samples analyzed, the pathogens isolated were bacterias followed by virus. In contrast to previous studies, in this study bacterias were isolated in higher proportion than virus. However, we are not able to conclude that bacterias or virus infections are responsible of the exacerbations, because it was not possible to found a strong association between the severity of the crisis and the presence of some pathogens.
