The role of the gut flora in health and disease, and its modification as therapy.

Hart AL, Stagg AJ, Frame M, Graffner H, Glise H, Falk P, Kamm MA.

The gut flora is a vast interior ecosystem whose nature is only beginning to be unravelled, due to the emergence of sophisticated molecular tools. Techniques such as 16S ribosomal RNA analysis, polymerase chain reaction amplification and the use of DNA microarrays now facilitate rapid identification and characterization of species resistant to conventional culture and possibly unknown species. Life-long cross-talk between the host and the gut flora determines whether health is maintained or disease intervenes. An understanding of these bacteria-bacteria and bacteria-host immune and epithelial cell interactions is likely to lead to a greater insight into disease pathogenesis. Studies of single organism-epithelial interactions have revealed the large range of metabolic processes that gut bacteria may influence. In inflammatory bowel diseases, bacteria drive the inflammatory process, and genetic predisposition to disease identified to date, such as the recently described NOD2/CARD15 gene variants, may relate to altered bacterial recognition. Extra-intestinal disorders, such as atopy and arthritis, may also have an altered gut milieu as their basis. Clinical evidence is emerging that the modification of this internal environment, using either antibiotics or probiotic bacteria, is beneficial in preventing and treating disease. This natural and apparently safe approach holds great appeal.


PARA's SUMMARY

THIS PAPER SUGGESTS THAT IN LIGHT OF THE FACT THAT NOD-2 IS RESPONSIBLE FOR HOST RESPONSE TO BACTERIAL PATHOGENS THAT MODIFICATION OF THE INTESTINAL FLORA VIA PROBIOTICS AND/OR ANTIBIOTICS WOULD BE BENEFICIAL FOR THE TREATMENT OF CD. AGAIN, SUGGESTING THAT CD IS INITIATED BY A MICROORGANISM
