ALEX³ Case No. 7

Ayleen, 16 years from China

Clinical history

Since age 1: atopic dermatitis, successfully treated; dry, itchy skin during viral illness. Since age 13: blemished skin with small itchy pustules; multiple washes and creams ineffective; diagnosed as hormonal acne, high-dose vitamin C prescribed, but no improvement.

Present situation

Ayleen still suffers a lot because of her blemished skin. Therefore, she consults a dermatologist who orders an ALEX³® allergy test.

Analysis

Malassezia sympodialis

  • Sensitisation to Malassezia sympodialis was detected
  • Mala s 11 is able to induce autoreactive T cells: plays an important role in atopic dermatitis

Aspergillus fumigatus

  • Sensitisation to spores of Aspergillus fumigatus was found that can cause allergic symptom like rhinoconjunctivitis or allergic asthma

Summary

  • Patient suffers from Malassezia allergy
  • Malassezia sympodialis is a yeast fungus commonly found in patients with atopic dermatitis
  • Especially seborrhoeic skin areas (e.g., head, neck) are preferred habitats
  • Consistent skin care is the basis of AD therapy
  • In case of skin inflammation in AD episodes, anti-inflammatory treatment is necessary
  • AD patients may benefit from antifungal therapy
  • Due to the strong cross-reactivity of Mn-superoxide dismutases, sensitisation to Aspergillus fumigatus could also be detected – but as Ayleen has no respiratory symptoms, therapy does not have to be considered
