Corticosteroid-induced contact dermatitis: a pragmatic approach

Area of Science:

• Dermatology
• Allergology
• Clinical Immunology

Background:

• The allergenic potential of topical corticosteroids has gained significant recognition in the last decade.
• This understanding has crucial implications for managing patients with chronic eczematous conditions.
• Nonhalogenated topical steroids have emerged as more frequent sensitizers compared to their halogenated counterparts.

Purpose of the Study:

• To highlight the growing awareness of topical corticosteroid allergy.
• To emphasize the clinical significance of this allergy in managing chronic eczematous eruptions.
• To recommend specific allergens for patch testing.

Main Methods:

• Review of recent findings on topical corticosteroid allergy.
• Clinical observations regarding sensitization patterns.
• Recommendations for diagnostic patch testing protocols.

Main Results:

• Nonhalogenated topical steroids are identified as more potent sensitizers.
• Tixocortol pivalate and budesonide are implicated as common allergens.
• Direct testing of patient-used topical steroid products is advised.

Conclusions:

• Tixocortol pivalate and budesonide should be incorporated into standard patch test allergen series.
• Testing of the specific topical steroid products used by patients is essential.
• Positive reactions to tixocortol pivalate or budesonide warrant further comprehensive corticosteroid series patch testing.
