Abstract
The results of a survey for a prospective study on the prognosis of infantile bronchial asthma are presented. In the addition, investigation into the factors associated with prognosis are also described. One hundred and thirty eight patients diagnosed as having infantile bronchial asthma in outpatients of Kudanzaka Hospital (Tokyo), during the period of 1972 to 1982, were studied. Out of 93 patients who answered the questionnaire 29 (31.2%) were in remission (no attack), 14 (15.1%) had several mild attacks every year which required no medication, 43 (46.2%) were in better condition but still had several attacks which needed medication, and the remaining 7 patients (7.5%) showed no remarkable change. On the basis of the foregoing results, the factors associated with these prognosis were investingated. There was a strong tendency toward poor prognosis in those cases which showed a high value of IgE, an IgE-RAST positive finding for house dust, milk and egg white.
