Asociaciones entre concentraciones de inmunoglobulinas en ni？os, factores ambientales de riesgo y morbilidad respiratoria

the objective of this paper was to identify the possible association between the concentrations of immunoglobulins, the exposure to environmental risk factors and the indicators of respiratory morbidity. 224 children from the zone exposed to the air pollution caused by transportation and 159 from the non-exposed zone were studied. parents were interviewed and a survey was done on the environmental risk factors, family history of respiratory disorders and respiratory symptomatology during the last 12 months. iga, igg, igm and ige were quantified. it was found a strong association of the elevated ige concentrations with the family pathological history of asthma, respiratory symptoms suggesting bronchial asthma and other respiratory diseases. the low igg concentrations were associated with the exposure to air pollution produced by transportation.
