BACKGROUND/OBJECTIVE: Alteration of intestinal flora was involved in the pathogenesis of atopic dermatitis. Patients with atopic dermatitis were less colonized with Lactobacilli or Bifidobacterium, whereas they were more colonized with Staphylococcus aureus or Enterobacteria. Consequently, fecal levels of bacterial metabolite (polyamines) were reduced. In contrast, stress also induced intestinal mucosal dysfunction against bacteria and impaired intestinal barrier function. We studied the effect of relaxation by viewing humorous films on fecal flora and fecal levels of polyamines.

METHODS: Twenty-four healthy individuals and 24 patients with atopic dermatitis either viewed seven control nonhumorous films or seven humorous films sequentially for 7 days. Before and after viewing, feces were obtained, and fecal flora and fecal levels of polyamines were assessed.

RESULTS: Neither viewing humorous films nor viewing control nonhumorous films had any effect on healthy individuals. In contrast, viewing humorous films
(i) increased colonization with lactobacilli and bifidobacterium,
(ii) decreased colonization with S. aureus and Enterobacteria, and
(iii) increased fecal levels of polyamines;
whereas viewing control nonhumorous films failed to do so in patients with atopic dermatitis.

CONCLUSION: Viewing humorous films may modulate fecal levels of polyamines by restoring intestinal flora in atopic dermatitis.
