Anecdotal data suggest that the amount of vitamin D available in the environment either from sunshine exposure or diet may be an important factor affecting the development of inflammatory bowel disease (IBD) in humans. We tested the vitamin D hypothesis in an experimental animal model of IBD. Interleukin (IL)-10 knockout (KO) mice, which spontaneously develop symptoms resembling human IBD, were made vitamin D deficient, vitamin D sufficient or supplemented with active vitamin D (1,25-dihydroxycholecalciferol). Vitamin D-deficient IL-10 KO mice rapidly developed diarrhea and a wasting disease, which induced mortality. In contrast, vitamin D-sufficient IL-10 KO mice did not develop diarrhea, waste or die. Supplementation with 50 IU of cholecalciferol (5.0 microgram/d) or 1, 25-dihydroxycholecalciferol (0.005 microgram/d) significantly (P < 0. 05) ameliorated symptoms of IBD in IL-10 KO mice. 1, 25-Dihydroxycholecalciferol treatment (0.2 microgram/d) for as little as 2 wk blocked the progression and ameliorated (P < 0.05) symptoms in IL-10 KO mice with already established IBD.
