  Purpose

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by exacerbations and remission of intensely pruritic lesions of variable location. AD may be acute (short-term and severe) with predominantly redness, vesicles and oozing, or it may be chronic (long-term) with scaling, skin thickening, altered pigmentation and exaggerated surface markings. The condition affects mainly the creases of the elbows and knees, and the face and neck, although it can affect any part of the body. The severity of AD is variable, ranging from localized mild scaling to generalized involvement of the whole body. Itching is the predominant symptom, which can induce a vicious cycle of scratching, leading to skin damage. There is a tendency to lifelong dry sensitive skin. Skin of AD is often colonized by Staphylococcus aureus contributing to perpetuating cutaneous inflammation. AD treatment is based on skin hydration, identification and elimination of flare factors, and pharmacologic therapy. Biofunctional textiles are emerging as new and complementary tools . Chitosan is a natural polysaccharide with in vitro anti-microbial activity and regenerating properties. The investigators aim to evaluate the effect of a textile coated with chitosan in AD treatment as well as its impact on systemic inflammation and skin microbiome. The investigators hypothesize the use of biofunctional textile coated with chitosan will improve severity of AD , quality of life and diminish skin colonization with Staphylococcus aureus and some skin moulds, namely Malassezia.

Primary Outcome Measures:
  • Score of severity of Atopic Dermatitis (SCORAD) [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    Investigator rated eczema severity: clinical improvement measured by local SCORAD (score of severity of AD)(initial versus final, % of change). SCORAD is composed of three different domains (A= extension B= intensity C = subjective symptoms)

  • Quality of life [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    Changes in Quality of life. Patients are asked to answer the Portuguese version of the Dermatology Life Quality Index (> 16 years old) or the children´s Dermatology Quality of Life Index (4-16 years old) at the beginning and end of the study


Secondary Outcome Measures:
  • Participant rated symptoms of eczema [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    Participant rated symptoms of eczema: patients are asked to record the severity scores of itchiness and sleep disturbance of the previous day in a diary card (10 point scale from 0-none to 10-extreme)

  • Need of eczema treatment [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    Patients are asked to record the use of topical steroids, antihistamines, oral steroids or immunosuppressive drugs on a diary card

  • Immunological serum markers [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    Changes in serum total IgE, specific IgE to enterotoxin A,B, C and TSST (staphylococcus enterotoxins) serum eosinophil cationic protein (ECP), blood eosinophils, C reactive protein. Changes in cytokine serum levels (RANTES, Interleukin-31, IL-18, IL-16).

  • Skin microflora [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    characterize the skin microflora of 25 cm2 of popliteal, brachial intertriginous areas , interscapular and occipital region and determine the changes in number of colony forming units of Staphylococcus aureus and moulds at the beginning and end of study.

  • Genetic mutations [ Time Frame: 2 months ] [ Designated as safety issue: No ]
    Presence of the seven most common fillagrin gene mutations including R501X and c.2282del4
