Enteral nutrition therapy with liquid diet has been shown to be effective
in achieving clinical remission in intestinal Crohn's disease. The mechanism
of action of this therapy, however, is still poorly understood. As part of our
assessment of the action of 3 related polymeric enteral therapies, we have
used a variety of techniques to document the histological and cytokine
responses, in the mucosa and, systemically, to these treatments. The feeds
studied (AL110, Modulen IBD and ACD004 [Nestle, Vevey, Switzerland]) all have
casein as the protein source, are lactose free and are rich in transforming
growth factor β (TGF-β). They have all been shown to induce clinical
remission associated with mucosal healing. In the case of Modulen IBD, as well
as mucosal macroscopic and histological healing there was a fall in mucosal
proinflammatory cytokines: interleukin-1 mRNA in colonic and ileal,
interleukin-8 mRNA in the colon and interferon

mRNA in the ileum, but
a rise in the regulatory cytokine TGF-β mRNA in the ileum. These results
indicate that these formulas are influencing the disease process itself, and
thus suggest that the clinical remission achieved is a result of a reduction
in inflammation, rather than a consequence of some other nutrition effect.
