RESUMO

A asma de esforço ou asma induzida pelo exercício (AIE), é uma síndroma que afecta não só os doentes com asma brônquica (AB), clínicamente reconhecida, como em menor percentagem, a população em geral. O diagnóstico é geralmente simples, se o médico estiver sensibilizado para os sintomas subtis que podem estar presentes durante ou após o esforço.

Há uma evidência crescente de que o arrefecimento e secura das vias aéreas, induzem uma mudança na osmolaridade, com consequente libertação de mediadores inflamatórios e redução do calibre das vias aéreas.

A prova de esforço deve ser executada para estabelecer o diagnóstico. Pode ser realizada em laboratório ou corrida ao ar livre. A propósito da metodologia diagnóstica, é efectuada uma breve revisão com o objectivo de sensibilizar a importância da AIE, por vezes subdiagnosticada, por utilização não criteriosa do tipo de prova laboratorial seleccionada.

ABSTRACT

The exercise-induced asthma (EIA), is a syndrome that affect not only the asthmatics patients, recognized clinically as in smaller percentage, the general population. The diagnosis is usually easy, if the doctor will be sensitized for the subtle’s symptoms, that can be present during or after the exercise.

The respiratory heat loss as well as respiratory water loss, have been proposed as current explanation of EIA, with consequent libertation of preformed and newly generated spasmogenic mediators and reduced the airway lumen.

The exercise test, must be used to establish the diagnosis. It can be realized in laboratory or free-running test. The purpose of the methodology is effectuate a brief revision with the aim of to enhance the importance of EIA, sometimes subdiagnosed for criterions not utilized of pattern’s laboratorial test choosed.
