Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Symptom severity of atopic dermatitis measured using the Severity Scoring of Atopic Dermatitis (SCORAD) index on day 0 (baseline), week 6, week 12 (end of low-molecular-weight fucoidan/placebo), and week 16 (end of the trial) | — |
Secondary
| Measure | Time frame |
|---|---|
| The following questionnaires were completed at baseline, week 6, week 12 and week 16: 1. Quality of life measured using the validated Chinese version of the Dermatology Life Quality Index (DLQI) questionnaire for patients over 16 years old, and the Children’s Dermatology Life Quality Index (CDLQI) questionnaire for patients under the age of 16 years old 2. Sleep quality measured using the validated Athens Insomnia Scale (AIS) Chinese version (CAIS-8) The following parameters related to the immune system were measured in blood samples at baseline, week 12, and week 16: 3. Parameters related to the immune system, including IgE, white blood cells, eosinophil, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), interleukin (IL)-4, IL-12, IL-13, interferon-? (IFN-?), and the percentage of CD4+ and CD8+ T cells. Blood samples from participants were sent to the department of Laboratory Medicine in Taoyuan Chang Gung Memorial Hospital for testing of IgE, WBC, eosinophil, ESR, CRP, AST, and ALT. For examination of lymphocyte subsets, samples were labeled with antibodies against CD4 and CD8 (BD Biosciences, San Jose, USA). The samples were analyzed by flow cytometry using appropriate isotype controls. Cytometry analyses were performed using BD FACSCanto™ II Clinical Flow Cytometry System equipped with FASDiva Software (BD Biosciences). Serum cytokines levels (IL-4, IL-12, IL-13, Interferon-?), were measured by an enzyme-linked immunosorbent assay (ELISA) using commercially available kits according to the manufacturer's instructions (Quantikine, R&D System, Minneapolis MN, USA). 4. The average frequency of using western medicine (steroid ointment or oral antihistamine) measured using patient-reported diaries on the days/week during baseline, weeks 1-6, weeks 7-12, and weeks 13-16 | — |
