Lanolin allergenicity is the focus of the “Contact Allergen of the Year” article in the peer-reviewed journal Dermatitis, the official journal of the American Contact Dermatitis Society (ACDS).
Lanolin and its derivatives are widely used in topical formulations for skin, lips, nails, and hair; they also have many industrial uses. Lanolin’s allergenicity remains controversial, and appropriate patch testing to detect lanolin allergy remains a topic of dispute.
Coauthors Blair Jenkins, MD, PhD and Donald Belsito, MD, MBA, from Columbia University Irving Medical Center, examine how common lanolin allergy is in the general population, and what is the appropriate screening allergen for lanolin. Although they describe lanolin as a “weak sensitizer,” they identify special populations for which the concern for lanolin allergy may be greater. These include people with stasis dermatitis/chronic venous insufficiency, chronic leg ulcer, or perianal and genital dermatitis, patients with atopic dermatitis, children, and the elderly.
“Detection of lanolin allergy by patch testing is challenging because ‘allergic’ patients may tolerate lanolin on healthy skin yet develop contact dermatitis when products containing lanolin are used on inflamed skin. This article succinctly describes the properties of this fascinating allergen and the challenges of confirming the diagnosis of lanolin allergy,” stated Editor-in-Chief of Dermatitis Anthony Gaspari, MD, from the Sidney Kimmel Medical College of Thomas Jefferson University.
Dermatitis® is a peer-reviewed scientific journal in contact dermatitis, publishing research in atopic, contact, occupational, environmental,and drug dermatitis. International in scope, the journal publishes research related to immunobiology of atopic dermatitis therapy, descriptions of important findings that result from clinical, translational, or basic research related to the mentioned types of dermatitis, epidemiology and population studies, health care disparities, skin of color, and allergy/patch testing in atopic dermatitis. It is the Official Journal of the American Contact Dermatitis Society (ACDS).
