Long-term effects of prematurity were airway obstruction and a lower CO diffusing capacity compared with control subjects, although mean lung function parameters were within the normal range. Ex-preterms had a lower exercise level, which could not be explained by impaired lung function or smoking habits, but might be due to impaired physical fitness.

In a randomized double-blind multicenter clinical study, 116 children with asthma were randomly assigned to treatment with an inhaled beta-2-agonist (salbutamol 0.2 mg) plus an inhaled corticosteroid (budesonide 0.2 mg) three times a day (BA+CS) or to an inhaled beta-2-agonist (salbutamol 0.2 mg) plus a placebo three times a day (BA+PL). After a median follow-up time of 22 months, 26 patients receiving BA+PL (45%) had withdrawn from randomized treatment, mainly because of asthma symptoms, compared with three withdrawals in the patients receiving BA+CS (p less than 0.0001). The FEV1, expressed as a percentage of the predicted value for age, sex, and height, showed an absolute increase of 7.0% after 2 months of BA+CS compared with a decrease of 4.0% after 2 months of BA+PL. This 11% difference in percent predicted FEV1 (95% confidence interval, 7 to 15%; p less than 0.0001) was then maintained after a median follow-up period of 22 months. Postbronchodilator FEV1 showed an absolute increase of 3.7% predicted within 2 months in patients receiving BA+CS and an absolute decrease of 1.1% predicted in children receiving BA+PL (p = 0.0005). Thereafter, this difference between the two treatment groups was maintained. Average peak expiratory flow rate (PEFR) increased from baseline by 36.6 L/min in the BA+CS group compared with 3.7 L/min in the BA+PL group (p = 0.003). This difference then remained for the median follow-up time of 22 months.(ABSTRACT TRUNCATED AT 250 WORDS)

The FAQLQ-CF is the first self-administered disease-specific HRQL questionnaire for food-allergic children. This questionnaire has a strong internal consistency and cross-sectional validity. It discriminates between children who differ in number of food allergies, and it was short and easy to use in the population studied. Therefore, the FAQLQ-CF may be a useful tool in clinical research.

HRQL is impaired in food allergic adolescents and adults, compared to the general population, and it is intermediate in magnitude between DM and RA, asthma and IBS. Children show the least impact on generic HRQL from food allergy.

Studies in adults revealed that addition of salmeterol to a moderate dose of inhaled corticosteroid resulted in better symptom control and higher PEF compared with doubling the dose of inhaled corticosteroid. The aim of this three group study was to compare the effects of a moderate dose of beclomethasone, the same dose of beclomethasone with salmeterol, and a doubling dose of beclomethasone on lung function and symptoms in children with moderate asthma. A total of 177 children already treated with inhaled corticosteroids, were randomized in a double-blind parallel study either to salmeterol 50 microg twice daily (BDP400+salm), beclomethasone 200 microg twice daily (BDP800), or placebo (BDP400) in addition to beclomethasone 200 microg twice daily. No significant differences between groups were found in FEV1, PD20 methacholine, symptom scores, and exacerbation rates after 1 yr. Salmeterol resulted in slightly better PEF in the first months of treatment. FEV1, and PD20 methacholine significantly improved in all groups. After 1 yr mean changes in FEV1, percent predicted were 4.3% (95% CI 1.3; 7.2), 5.8% (95% CI 2.9; 8.7), and 4.3% (95% CI 2.1; 6.5) for BDP400+salm, BDP800, and BDP400, respectively. Changes in airway responsiveness were 0.60 (95% CI 0.05; 1.14), 1.30 (95% CI 0.73; 1. 87), and 0.80 (95% CI 0.33; 1.27) doubling doses. Growth was significantly slower in the BDP800 group. We conclude that no additional benefit was found of adding either salmeterol or more beclomethasone to a daily dose of 400 microg beclomethasone in this group of children with excellent compliance of medication.
