Etiological factors in child bronchial asthma

Available statistics regarding the different activating mechanisms of asthma vary greatly and they are a product of an era wherein only the extrinsic factors were considered to be fundamental in the etiology of bronchospasm. For the present study were selected 700 clinical case histories of children suffering from bronchial asthma. Emphasis was placed on the sex, age of onset, family history, presence of associated allergic disorders, intracutaneous tests and their relation to the anamnesis and evolution of the disease in the treatment period for no less than three years. A purely bacterial cause, without other types of sensitization involved, was present in 54% of the cases, on the contrary, purely extrinsic factors were present in 10% of the cases, summing up to 46%, if their role in the mixed group is taken into consideration. The high percentage of bacterial asthma (94.7%) was found fundamentally in children below one year of age. The results obtained in this demonstrate the great importance of the bacterial factor in child bronchial asthma.
