简要总结

Atopic eczema causes significant disease burdens worldwide. Some studies reported gastrointestinal symptoms in eczema patients which could be related to gut microbiota change. A unique gastrointestinal microflora pattern has also been observed in atopic dermatitis patients when compared with healthy controls. To date, no adult formula is specific for alleviating atopic eczema-related symptoms (especially through change of gut microbiota) for adults. The investigators hypothesize that the gut microbiota of adults with atopic eczema can be modulated to decrease the severity of atopic eczema-related symptoms. A pilot study is proposed to assess the effect and safety of SIM05 on atopic eczema severity and gut microbiome of adults with atopic eczema.

详细描述

The major atopic disorders, atopic eczema, allergic rhinitis and asthma, cause significant disease burdens worldwide.

Apart from cutaneous symptoms such as dryness and itchiness in eczema patients [4], studies also reported gastrointestinal symptoms which could be related to gut microbiota change. Unique gastrointestinal microflora pattern has also been observed in atopic dermatitis patients when compared with healthy controls: decreased Bifidobacterium and Enterococci, especially Bifidobacterium bifidum and Bifidobacterium longum, and increased Faecalibacterium have been observed. Therefore, gastrointestinal microflora can serve as the disease indicator of atopic eczema. Emerging evidence also suggests that gut microbiota modulation can largely affect host immune functions in adults.

To date, no adult formula is specific for alleviating atopic eczema-related symptoms (especially through change of gut microbiota) for adults. SIM05 contains a blend of naturally occurring three food-grade probiotics strains and three prebiotics. The three probiotics belong to food-grade Bifidobacterium and Lactobacillus, which is an important group of probiotic cultures commonly used in food products. Moreover, research showed that Lactobacillus and Bifidobacteria could prevent atopic sensitisation to common food allergens and thus reducing the incidence of atopic eczema.

The investigators hypothesize that the gut microbiota of adult with atopic eczema can be modulated to decrease the severity of atopic eczema related symptoms. A pilot study of 30 adults with atopic eczema who will receive SIM05 for 16 weeks is proposed to assess the effect and safety of SIM05 on atopic eczema severity and gut microbiome.

结局指标

主要结局

Change in Eczema Area and Severity Index (EASI) across 16 weeks.

时间窗: 16 weeks

The change of score in Eczema Area and Severity Index. A score of 0 indicates clear or no eczema, 0.1 to 1.0 indicates almost clear, 1.1 to 7 indicates mild disease, 7.1 to 21 indicates moderate disease, 21.1 to 50 indicates severe disease, and greater than 51 indicates very severe disease.

次要结局

  • Change in Dermatology life quality index (DLQI) across 16 weeks.(16 weeks)
  • Percentage of subjects achieving 50% and 75% reduction in EASI (EASI-50, EASI-75).(16 weeks)
  • Changes in faecal microbial profiling across 16 weeks.(16 weeks)
  • Adverse events reported during the study period.(16 weeks)
  • Change in pruritus numerical rating scales (pruritus-NRS) across 16 weeks.(16 weeks)
