AD Patients’ Reactions to Personal Care Products

J Am Acad Dermatol; ePub 2018 Jul 24; Rastogi, et al

Atopic dermatitis (AD) patients had more positive patch test reactions to ingredients in personal care products, topical steroids, and antibiotics, according to a recent study. A retrospective chart review was performed of 502 adults (aged ≥18 years) who were patch-tested to an expanded allergen series from 2014-2017. Researchers found:

  • Overall, 108 (21.5%) had current AD and 109 (21.7%) had past AD.
  • Patients with vs without current AD had similar proportions of any positive (+/++/+++: 80 [74.1%] vs 254 [64.5%]), stronger (++/+++: 34 [31.5%] vs 102 [25.9%]), and irritant (56 [51.9%] vs 188 [47.7%]) patch test reactions.
  • AD patients had significantly higher rates of positive reactions to ingredients in personal care products and topical medications, including fragrance mix II, lanolin, bacitracin, cinnamal, budesonide, tixocortol, and chlorhexidine; relevance was established in >90% of these reactions.
  • Polysensitization occurred more commonly in patients with vs without AD (35 [32.4%] vs 75 [19.0%]).
