Abstract
Skeletal maturation in severe bronchial asthma was studied in 15 children during and after treatment with depot tetracosactrin and in 6 children during treatment with prednisolone. Attained skeletal maturity before treatment was below the reference mean in the majority of children. Skeletal maturation was enhanced during treatment with depot tetracosactrin, which led to more advanced attained skeletal maturity at withdrawal than at start of treatment. There was a tendency towards larger increases of skeletal maturity than of height. The influence of adrenal androgens, released by ACTH-stimulation and good control of the disease are probably relevant factors for the acceleration of skeletal maturation. After withdrawal of depot tetracosactrin the rate of skeletal maturation normalized. During prednisolone treatment there was a delay of skeletal maturation leading to a progressive relative decrease of attained skeletal maturity, and closely related to a delay in linear growth. Treatment with depot tetracosactrin may thus induce enhancement of skeletal maturation, but with the treatment regimen found to be efficacious in bronchial asthma, the effect is not very pronounced and does not perceptibly affect the ultimate outcome of growth.
