Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.
