New data regarding Wet Wipe Allergens from the North American Contact Dermatitis Group!

There have been several case reports of wipe-associated contact dermatitis, however, the aim of this study was to determine the prevalence of wipe-associated contact dermatitis in a larger population This study looked at 9037 patients patch tested from 2011-2014 to determine the prevalence of wet wipes as a source of contact allergy.

What did they find?

79(0.9%) had a positive patch test to an allergen associated with a wet-wipe source. Anal/genital dermatitis was 15 times more likely in those with a wet-wipe allergy!

What were the most associated allergens

Preservatives and fragrance:

  1. Methylisothiazolinone (59.0%)
  2. Methychloroisothiazolinone (MCI)/MI (35.6%)
  3. Bronopol (2-bromo-2-nitropropane-1,3-diol) (27.4%)
  4. Iodopropynyl butylcarbamate (12.3%)
  5. Fragrance (combined) represented (12.3%)

What was their conclusion?

Although uncommon (0.9%), Wet wipes are an important source of contact allergy to consider with anal/genital dermatitis. Preservatives such as Isothiazolinones are an especially important source to consider!

  • As gluten allergy becomes more prevalent and widely-knownin society, patients with cutaneous or gastrointestinal symptoms following wheat ingestion may self-report gluten/wheat allergies, though they do not in fact have celiac disease. Almaco et al. suggested the term “non-celiac wheat sensitivity” (NCWS) to describe patients presenting with these symptoms, rather than non-celiac gluten sensitivity (NCGS), as it is not known which component of wheat causes the symptoms.
  • Non-celiac wheat sensitivity (NCWS) is a relatively new clinical finding associated with gluten-related diseases. Wheat contains nickel, a known contact allergen, which may produce systemic nickel allergy syndrome (SNAS) symptoms. Nickel is the most frequent cause of contact allergy in tested populations.
  • NCWS can mimic irritable bowel syndrome (IBS). 
  • Almacoet al. conducted a double-blind placebo-controlled (DBPC) experiment in order to evaluate the frequency of contact dermatitis due to nickel allergy.

o   NCWS patients suffering from nickel allergy were compared with a control group of NCWS patients who did not report nickel allergy.

o   NCWS patients with nickel allergy had a significantly higher percentage of atopic disease manifestations than those with irritable bowel syndrome (IBS) and NCWS patients without nickel allergy.

  • Nickel allergy (diagnosed by a confirmatory epicutaneouspatch test) may manifest with both cutaneous and gastrointestinal symptoms.

o   All NCWS patients with nickel allergy exhibited cutaneous erythema.

o   Less than 10% of NCWS patients without nickel allergy exhibited such symptoms.

  • Causes may include dietary short-chain carbohydrate load, autoimmune disorders, and non-immunoglobulin E – mediated wheat allergies.
  • This study did not allow for evaluation of the frequency of nickel allergy in NCWS; nickel patch testing was only performed on patients who self-reported contact dermatitis. Nickel allergy could have been present in patients who did not report nickel allergy.
  • Selection bias was a result of patients referred to tertiary centers.
  • Alcamo et al. suggest that patients with NCWS who exhibit cutaneous erythema should be tested for nickel allergy.
