Insights
Potent topical steroids can suppress the hypothalamic-pituitary-adrenal (HPA) axis in infants, leading to serious side effects like liver issues. Physicians and parents must be aware of these risks and avoid prolonged use.
Area of Science:
- Pediatric Endocrinology
- Dermatology
- Pharmacology
Background:
- Topical corticosteroids, when applied long-term, can suppress the hypothalamic-pituitary-adrenal (HPA) axis.
- Infants are at higher risk for Cushing's syndrome or adrenocortical insufficiency due to potent glucocorticoid absorption through the diaper area.
- This study reports on six infants exposed to potent topical corticosteroids without a prescription.
Observation:
- Infants aged 3-8 months were exposed to potent topical corticosteroids (clobetasol propionate, diflucortolone valerate).
- Clinical examinations and laboratory tests were performed to assess HPA axis function and other side effects.
- Abdominal ultrasonography was used to detect hepatosteatosis.
Findings:
- All infants showed HPA axis suppression confirmed by ACTH stimulation tests.
- Hepatomegaly was present in all infants, with hepatosteatosis in three.
- Elevated liver transaminases were observed in five infants; one infant died from Cytomegalovirus infection.
Implications:
- Physicians must recognize and manage the dangerous side effects of potent topical steroids in infants.
- Long-term use of potent topical corticosteroids in infants should be avoided.
- Informed consent regarding potential side effects is crucial when prescribing topical steroids for infants.
Background:
Prolonged application of topical steroids transiently suppresses the hypothalamic-pituitary-adrenal axis (HPA). Infants who are exposed to topical corticosteroids have greater risk for Cushing's syndrome or adrenocortical insufficiency caused by suppression of the HPA axis because glucocorticoids are highly absorbed through the diaper area. Here, we report six infants (four girls, two boys) aged between 3 and 8 months who were exposed to potent topical corticosteroids (clobetasol propionate and diflucortolone valerate) by the mother's application without prescription.
Methods:
We examined the HPA axis and other side effects of the potent glucocorticoid therapy in these infants. After stopping the topical corticosteroid, serum AST, ALT, lipids, morning cortisol and ACTH levels were measured. A low dose ACTH stimulation test was carried out. Hydrocortisone was started for the prevention of glucocorticoid withdrawal syndrome and the dose was gradually decreased. Abdominal ultrasonography was performed to investigate hepatosteatosis.
Results:
The ACTH stimulation test showed suppression of the HPA axis in these infants. Hepatomegaly was found in all infants and three of them had hepatosteatosis. Liver transaminase levels were elevated in five infants. Five patients have been followed for 6-14 months. One infant died due to generalized Cytomegalovirus infection.
Conclusion:
We emphasize that physicians should be alert for the dangerous side-effects of topical steroids and they should avoid long-term use. Furthermore, parents should be informed about the side-effects when topical steroid treatment is chosen.

Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.
