To explore the hypothesis that there is an increased metabolic rate in cystic fibrosis, resting energy expenditure was measured by indirect calorimetry in 23 subjects with cystic fibrosis in a stable clinical state and in 42 normal control subjects. Resting energy expenditure was found to be elevated by an average of 0.45 MJ/24 h [95% confidence interval(More)
The diets of 20 children with cystic fibrosis were analysed for energy and nutrient content with simultaneous measurement of energy losses in stools. Median energy intakes were in excess of the WHO estimated daily requirements (118.2%) when expressed as MJ/kg/24 hours, the excess almost accounted for by energy losses in the stools. When expressed as MJ/24(More)
Plasma cortisol was measured every 20 min and sleep was monitored in nineteen asthmatic children, twelve of whom were receiving various doses of inhaled beclomethasone dipropionate (BDP). Children receiving inhaled BDP had lower cortisol secretion during the night than those who were not taking inhaled BDP, a delayed rise from the nocturnal nadir, and low(More)
BACKGROUND Allergic bronchopulmonary aspergillosis is a serious complication of cystic fibrosis and may be difficult to diagnose. The aim of this study was to define the usefulness of measuring total IgE compared with other major criteria in the diagnosis of allergic bronchopulmonary aspergillosis in children with cystic fibrosis. METHODS A retrospective(More)
BACKGROUND Radiological estimates of hyperinflation are used in several clinical and radiographic scoring systems for cystic fibrosis, but it is not known if these estimates of hyperinflation are related to measured total lung capacity. METHODS Comparison was made of independent clinical estimates of hyperinflation from chest radiographs with objective(More)
BACKGROUND Manufacturers of ionisers claim many benefits from the use of their devices, including the relief of asthma. Particles removed from the air are likely to include airborne allergens, so ionisers may achieve an effect by reducing the allergen load. METHODS The effect of ionisers on airborne concentrations of house dust mite allergen Der p I was(More)
The parents of all children attending the Royal Brompton National Heart and Lung Hospital cystic fibrosis paediatric clinic were asked to complete an anonymous postal questionnaire addressing attitudes towards prenatal diagnosis and population carrier screening for cystic fibrosis (CF); 65% (170/261) of parents responded. Of the respondents, 92% would(More)
The safety of inhaled corticosteroids in the treatment of chronic asthma has been questioned. In a prospective crossover study asthmatic children not controlled on other medications were commenced on beclomethasone dipropionate (BDP) or budesonide (BUD), both administered at the dose of 200 micrograms twice per day for 2 wk each in randomized order.(More)
We have previously demonstrated dose-dependent nocturnal cortisol suppression by inhaled beclomethasone and budesonide in asthmatic children. This has now been confirmed in a controlled study. Eighteen healthy adults inhaled either a single evening dose of 400 micrograms budesonide or placebo or 400 micrograms budesonide twice daily for 2 wk. Overnight(More)
OBJECTIVES Despite improved nutrition and intensive treatment, subjects with cystic fibrosis have difficulty in maintaining anabolism during intercurrent infections, which can result in reduced body mass index and impaired skeletal growth. Insulin-like growth factor-I (IGF-I) and its binding protein IGFBP3 are sensitive to changes in nutritional status. The(More)
