Energy intake and energy expenditure in prepubertal males with asthma.

This study aimed to measure energy intake (EI) and total energy expenditure (TEE) of asthmatic males and to validate diet history as a method of estimating their energy requirements. EI was assessed by dietary history and TEE by the heart-rate monitoring method in a group of asthmatic and nonasthmatic males. Resting energy expenditure (REE) adjusted for fat-free mass was higher in asthmatic than in nonasthmatic males (5,037 versus 4,839 kJ x day(-1), p<0.05). TEE (93+/-1.8 versus 8.4+/-1.4 MJ x day(-1), respectively; p=NS) and EI (9.2+/-15 versus 8.8+/-15 MJ x day(-1), respectively, p=NS) were not statistically different in asthmatic and nonasthmatic male. EI was not statistically different from TEE in both groups of males. Asthmatic males showed an acceptable agreement between TEE and EI at the individual level (range of agreement: -3.2 to 2.9 MJ x day(-1)), and a good agreement at the group level (95% confidence interval for the bias, - 1.1 to 0.8 MJ x day(-1)). Males with mild-to-moderate asthma have a higher metabolic activity per unit fat-free mass than nonasthmatic males. This increased requirement is apparently well compensated by an adequate energy intake. Diet history is a suitable method for estimating energy requirements in males with mild-to-moderate asthma.

Inhaled formoterol in the prevention of exercise-induced bronchoconstriction in asthmatic children.

The duration and magnitude of the effect of inhaled formoterol (12 micrograms) against exercise-induced bronchoconstriction (EIB) was compared with that of inhaled salbutamol (200 micrograms) and that of placebo in 15 children with asthma and EIB in a double-blind, double-dummy, within-patient, placebo-controlled study. The treatments were given by metered dose aerosol on three different days. The exercise test was performed at the 3rd and the 12th hour after dosing. The magnitude of the blocking effect was assessed both by evaluating the lowest FEV1 reading obtained within an hour after each exercise test and by considering the percent decrease below the baseline FEV1 measured before drug administration. Comparison of the lowest values obtained during the hour after each exercise test shows that formoterol was significantly better than both salbutamol (p = 0.022), and placebo (p = 0.001) in limiting exercise-induced bronchoconstriction after the first exercise test (3 h after dosing), while no difference was observed between salbutamol and placebo (p = 0.198). After the second exercise test (12 h after dosing), formoterol again proved to be more effective than both salbutamol (p = 0.008) and placebo (p = 0.001), and no significant difference was observed between salbutamol and placebo (p = 0.391). The evaluation of the mean percentage decrease in FEV1 confirmed the results in favor of formoterol in both the exercise tests. No adverse effects were reported in any treatment group. The protection against EIB is significantly more prolonged after formoterol than after salbutamol, and persists for 12 h after dosing.
