title: Tailoring Treatment to the Individual Patient - Will Inflammatory Bowel Disease Medicine Be Personalized?
abstract: Personalized medicine is variably defined as a new system aimed at providing optimal medical care by using comprehensive pathophysiology-based information on all aspects and components of a disease process to prevent, diagnose and treat in ways that are custom-made for the individual patient. The need for personalized medicine derives from the realization that today's most challenging medical conditions are chronic complex diseases with multiple pathogenic components that interact with each other. Complexity and interaction together create unique molecular pathways that are only relevant to certain disease subtypes, but not to the entire population of patients with the same diagnosis. Thus, complex diseases cannot be properly controlled, and much less cured, by modulating single components at sporadic time points in the course of the disease or administering the same treatment to all patients, as we currently do in the management of inflammatory bowel disease (IBD). The implementation of personalized medicine requires entirely novel and methodologically sophisticated bioinformatics-based approaches that use comprehensive and detailed information on the various components ('omes') of the disease process. This requires identifying the key controllers ('hubs') of pathogenic pathways in a totally unbiased fashion and discovering highly specific agents that can selectively block or even revert pathogenic events. IBD is a perfect example of a condition with multiple causes and multiple mechanisms, and IBD patients will unquestionably benefit from the adoption of personalized medicine in the near future.
