[Adrenal function and lipid metabolism in asthmatic children treated with budesonide]. / Función adrenal y metabolismo lipídico en niños asmáticos tratados con budesonida.

OBJECTIVE: To assess the effect of low doses of inhaled budesonide on the adrenal function and lipid metabolism of asthmatic children. MATERIAL AND METHODS: The study included 10 asthmatic children (mean age, 8.8 years) treated with inhaled budesonide (200-300 micrograms/day) for a period longer than 3 months (group A); 15 asthmatic children (mean age, 7.8 years) without steroid treatment (group B) and 10 non-asthmatic children (group C). Basal cortisol levels, as well as postACTH, adrenal androgens, lipids and urinary cortisol were determined. RESULTS: No significant differences were detected between groups A and B in the studied variables. In asthmatic children, urinary cortisol was significantly higher than in non-asthmatic children. Triglycerides, total cholesterol, low density lipoprotein cholesterol and atherogenic index levels were higher in asthmatic children with and without budesonide treatment, compared with non-asthmatic children. CONCLUSIONS: Treatment of asthmatic children with low doses of inhaled budesonide did not modify the adrenal axis function nor lipid metabolism. Asthmatic patients showed an atherogenic lipid profile which could increase the risk of cardiovascular disease.
