Patch Test Series for Allergic Perineal Dermatitis in the Diapered Infant

Area of Science:

• Pediatric Dermatology
• Allergen Identification
• Contact Dermatitis

Background:

• Allergic perineal dermatitis (PD) in infants is often caused by diapers, wipes, or topical treatments.
• Standard patch testing for allergic contact dermatitis in children has limitations, including body surface area, patient tolerance, and false positives.
• A targeted approach is needed to effectively screen infants for allergic PD.

Purpose of the Study:

• To propose two novel patch test series designed to screen infants for allergic perineal dermatitis (PD).
• To develop a more efficient and accurate diagnostic tool for identifying the causes of allergic PD in infants.

Main Methods:

• Allergens were selected based on existing sensitization data in children.
• Published case reports of allergic PD were reviewed.
• Expert opinion from American Contact Dermatitis Society members was gathered via an electronic survey.

Main Results:

• PD series 1 comprises 23 allergens commonly found in wet wipes and topical diaper preparations.
• PD series 2 includes 10 allergens frequently present in diapers.
• These series aim to cover the most probable causes of allergic PD in infants.

Conclusions:

• The proposed patch test series are judiciously designed to enhance the detection rate of allergic PD causes.
• These targeted series minimize patient exposure to a large panel, reducing potential irritant reactions.
• The study aims to improve the diagnostic yield for allergic contact dermatitis in diapered infants.
