Patients in long-term care facilities face an elevated risk of C. difficile infection, a life-threatening disease that could be managed more effectively with a precision medicine treatment plan. <\/p>\n
To discover new treatments for this life-threatening intestinal condition, researchers at theBiocomplexity Institute of Virginia Techhave employed a combination of algorithms, simulations, and machine learning. These novel research techniques allowed scientiststo make significant progress toward new precision medicine treatment options for patients suffering fromC. difficileinfections (CDI). <\/p>\n
TheNutritional Immunology and Molecular Medicine Laboratory(NIMML), a leading lab at the Biocomplexity Institute, has developed a computational pipeline to test and predict the efficacy of existing and novel treatments for infectious and immune-mediated diseases. The pipeline incorporates mechanistic ordinary differential equation-based models with stochastic simulation and advanced machine-learning methods. <\/p>\n
Researchers built upon an existinginteraction modelto develop the pipeline, which can now translate preclinical results in animal models to clinical outcomes, identify effective treatments, examine dosage effects, and predict patient reactions to combination therapies. The research study, recently published inArtificial Intelligence in Medicine,illustrates the development of a computational pipeline to test and predict the efficacy of existing and novel treatments for CDI. <\/p>\n
The convergence of advanced data analytics, modeling, and artificial intelligence systems with high resolution, large-scale patient data creates an opportunity to fundamentally transform how medicine will be practiced, said Josep Bassaganya-Riera, director of NIMML and CEO ofBioTherapeutics, Inc. In this study and in our continuing efforts, we aim to be a leader in this developing field of precision, personalized medicine in infectious and autoimmune diseases. <\/p>\n
Modeling systems, such as this one, have the potential to revolutionize the design of treatment regimes away from the one-size-fits-all therapeutic approaches into a golden age of personalized disease treatment. Integration of patient characteristics from large-scale electronic health records can create virtual avatars to test new therapies and for predictive analytics to identify new molecular biomarkers capable of accurately predicting a patients response to treatment. <\/p>\n
The ability to predict progression of disease and response to treatment is of particular importance in CDI. The majority of health care costs and mortality resulting from CDI are caused by high rates of recurrence that can exceed 50 percent of patients, depending on the treatment. <\/p>\n
Antibiotics are currently the standard form of treatment for CDI, which run the risk of perpetuating drug-resistant bacterial strains, ultimately worsening the disease. Virginia Tech researchers say their new study points to a promising alternative treatment for CDI: a protein called lanthionine synthetase c-like or LANCL2. <\/p>\n
Our modeling shows that we do not need to remove the pathogen nor directly influence inflammation in the case of CDI to have an effective treatment, said Andrew Leber, scientific director at BioTherapeutics. Simply restoring immune tolerance in the gut through an LANCL2, or similar immunoregulatory pathway, or boosting the gut microbiome to allow it to naturally outcompete pathogenicC. difficilestrains is effective in the absence of antibiotics. <\/p>\n
This study serves as a critical first step toward demonstrating the feasibility of constructing precision medicine tools that can optimize treatment design on a patient-by-patient basis. The application of these methods to personalized treatment of human diseases can potentially minimize undesirable side effects and maximize efficacy of treatment in response toC. difficileand other infectious and immune mediated diseases. <\/p>\n
