Evaluation of Hypothalamic-Pituitary-Adrenal Axis Suppression following Cutaneous Use of Topical Corticosteroids in Children: A Meta-Analysis

Abstract

Background/Aims: A meta-analysis was performed to determine the likelihood of hypothalamic-pituitary-adrenal (HPA) axis suppression following short-term cutaneous treatment of atopic dermatitis with topical corticosteroids (TCS) in pediatric patients. Methods: All published pediatric clinical trials evaluating TCS use with pre- and post-treatment HPA axis assessment by cosyntropin stimulation testing were included. Results: Of 128 eligible trials, 12 were selected for meta-analysis with a total of 522 participants. There were 20 observed cases of HPA axis suppression (3.8%, 95% CI 2.4–5.8). The percentage of HPA axis suppression with low- (classes 6–7), medium- (classes 3–5) and high-potency (classes 1–2) TCS use was 2% (3 of 148 patients, 95% CI 0.7–5.8), 3.1% (7 of 223 patients, 95% CI 1.5–6.3), and 6.6% (10 of 151 patients, 95% CI 3.6–11.8), respectively. Conclusion: There is a low rate of reversible HPA axis suppression with the use of mid- to low-potency TCS compared to more potent formulations. In pediatric clinical practice, the limited use of mid- to low-potency TCS is rarely associated with clinically significant adrenal insufficiency or adrenal crisis. In the absence of signs and symptoms of adrenal insufficiency, there is little need to test the HPA axis of these patients.
