Among factors which possibly influence the responses of asthmatic children to exercise, climate has received little attention. This study was performed to determine whether the level of air humidity is a factor to be considered. Twenty asthmatic (extrinsic perennial) girls and boys, 6 to 14 yr of age, with unverified history of exercise-induced asthma (EIA) took part. They rested and exercised in a climatic chamber in dry (25% relative humidity) and humid (90%) sessions at 25 degrees to 26 degrees C. One to three weeks separated the sessions, the order of which was counterbalanced. No changes in pulmonary functions (FVC, FEV 1.0, MMEF, MBC) were found following a sitting period of 60 min in either climate. Five and ten minutes following the treadmill run, however, bronchoconstriction was distinctly more pronounced in the dry than in the humid climate. Exercise heart rate and the subjective rating of effort were not affected by climate. It was concluded that, under the above experimental conditions, EIA is more likely in dry air than in humid air, possibly due to heat loss at the airway mucosa caused by evaporation. High humidity of inspired air could be the reason why EIA is less prevalent in swimming, as compared with other modes of exercise.

The bronchodilatory effect of maprotiline (Ludiomil, firm Ciba-Geigy) was investigated in 20 patients with bronchospasm (FEV %below 60%). The effect of a single dose of 75 mg maprotiline was compared with that produced by 500 mg of aminophylline, applied each time in 500 ml normal saline during 90 min, on two different days, in randomized sequence, always at the same day time. Prior to and at 5, 10, 20, 30, 60, 90, 120, 150 and 180 minutes after commencement of the infusion the following parameters of pulmonary ventilation have been determined: VC, FEV1, FEV1%., MEFR and MBC. The stated differences between the efficacy of maprotiline and aminophylline were statistically not significant (p > 0.05). In 18 patients maprotiline caused sedation and even somnolence. The authors conclude that maprotiline is an efficacious bronchodilator in patients with bronchospasm and is well tolerated by the patients.
