The Benefits of Identifying and Treating Adrenal Suppression in Adult Difficult Asthmatics: A Case Series

Abstract

We present 7 adults atopic asthmatics that were referred due to repeatedly relapsing asthma requiring oral courses of prednisolone. All were steroid responsive yet steroid dependant and were screened for adrenal insufficiency after changes to inhaled therapy and other standard anti-asthma treatments failed to improve the situation. All were deemed to be compliant. 4 used long-term intranasal steroids in addition to inhaled corticosteroids. No topical steroid creams were used by these patients. Adrenal suppression was examined via a 9 am cortisol level and a short synacthen test (using intravenous tetracosactide 250 mcg) along with measurement of ACTH (Adreno-Cortico-Trophic Hormone). The tests were performed in periods off prednisolone. We report the observed beneficial effects after treatment of the adrenal insufficiency with hydrocor-tisone acetate replacement therapy in these cases, and the benefit to their exacerbations, hospital admission and the requirement for prednisolone courses. These patients would have been stepped up to yet higher doses of inhaled steroids and even referred for anti-IgE treatment etc. Adrenal suppression is well described in the medical literature for asthmatics, but the beneficial outcomes of treating this are unknown. These 7 cases have been followed for up to 3 years since hydrocorti-sone replacement therapy. Most improved to a stable asthma without frequent exacerbations nor requirement for prednisolone and only 1 had a hospital admission.
