General: Systemic absorption of topical corticosteroids can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for gluco- corticosteroid insufficiency after withdrawal from treatment. Manifestations of Cushing's syndrome, hyperglycemia, and glucosuria can also be produced in some patients by systemic absorption of topical corticosteroids while on treatment.

Patients applying a potent topical steroid to a large surface area or to areas under occlusion should be evaluated periodically for evidence of HPA axis suppression. This may be done by using the ACTH stimulation, A.M. plasma cortisol, and urinary free cortisol tests.

13Pediatric Subcommittee of the AIDAC of the AIDAC October October 29-30, 2003, 2003
If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Recovery of HPA axis function is generally prompt upon discontinuation of topical corticosteroids. Infrequently, signs and symptoms of glucocorticosteroid insufficiency may occur requiring supplemental systemic corticosteroids.

15Pediatric Subcommittee of the AIDAC of the AIDAC October October 29-30, 2003, 2003
Safety and effectiveness in children and infants have not been established. Because of a higher ratio of skin surface area to body mass, children are at a greater risk than adults of HPA-axis-suppression when they are treated with topical corticosteroids. They are therefore also at greater risk of glucocorticosteroid insufficiency after withdrawal of treatment and of Cushing's syndrome while on treatment.

HPA axis suppression, Cushing's syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in pediatric patients receiving topical corticosteroids. Manifestations of adrenal suppression in pediatric patients include low plasma cortisol levels to an absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema.

Criteria per protocol for a normal adrenal response to ACTH stimulation at 30 and 60 minutes:
Criteria per protocol for a normal adrenal response to ACTH stimulation at 30 and 60 minutes:
• Post stimulation serum cortisol >20 µg/dL
• If pre-stimulation serum cortisol levels > 20 µg/dL, an incremental increase >6 µg/dL in serum cortisol
• Post stimulation serum cortisol >20 µg/dL
• If pre-stimulation serum cortisol levels > 20 µg/dL, an incremental increase >6 µg/dL in serum cortisol
27Pediatric Subcommittee of the AIDAC of the AIDAC October October 29-30, 2003, 2003
Three patients according to the protocol criteria were suppressed:
2 patients, 1 an 18 month old, had a peak response of 5 µg/dL change from baseline. 1 patient had a post-stimulation cortisol value that decreased from baseline.
At that time, the Agency agreed with an outside endocrinologist that since these 3 patients had a post-stimulation response that was greater than 20 µg/dL, although they didn't have the required incremental rise, they would not be considered suppressed.
This led to the current label that reads that "none of the 59 patients showed evidence of HPA axis suppression."

SummarySummary
• HPA axis suppression does occur with the use of topical corticosteroids
• The adrenal suppression is not limited to the super potent class of topical corticosteroids
• The type of vehicle may contribute to the extent of absorption of the active chemical moiety
• The suppression appears, in most cases, to be reversible upon cessation of drug usage
