Evaluation of pituitary-adrenal function in patients with chronic bronchial asthma following substitution of steroid treatment with disodium cromoglycate (Lomudal).

In a group of 32 steroid-dependent asthmatic patients an attempt was made to replace steroid treatment with disodium cromoglycate (Lomudal). Withdrawal of steroids was accompanied by a transitory stage of combined corticotropin-Lomudal treatment for 6 to 8 mo. Pituitary-adrenal function was assessed by ACTH and Metopirone test. Before treatment an impairment of pituitary-adrenal function was found in most of our patients, although in 26 patients a normal increment of plasma cortisol was found after ACTH stimulation. At the end of the combined treatment, 17 patients are now on Lomudal with normal pituitary-adrenal function, 9 patients need small quantities of steroids occasionally, and 6 patients are steroid-dependent.
