The purpose of this study is to study the clinical effects of taking probiotics in patients
who have moderate to severe atopic dermatitis. There has been several studies showing
improvement in the severity of atopic dermatitis after taking probiotics. The mechanism of
this improvement is currently unknown. We propose that probiotics improve atopic dermatitis
by stimulating, or increasing, the activity of a special type of cell called the T Regulatory
cell--which can suppress the activity of allergic disease.
