Identifying Saliva Markers in Inflammatory Bowel Disease

Study Overview
=================
Brief Summary
-----------------
Under normal conditions intestinal mucosa presents a baseline physiological inflammation caused by a controlled immune response that eliminates offending dietary and microbial antigens. This inflammation disappears once the cause is eradicated. In case of inappropriate immunological response, the inflammation becomes chronic and harmful, resulting in anatomical and functional abnormalities, namely inflammatory bowel disease (IBD). Although it is critical for the IBD patients to undergo early diagnosis and management before the development of severe complications, but as IBD has vague and non-pathognomonic clinical features, the clinician is usually mislead into late suspicion and detection of IBD. Diagnosis traditionally depended on a combination of pathologic evaluation together with the histological, clinical, radiological, endoscopic, surgical, laboratory (serological) features. Recently, serological markers were identified and became of special interest as they do not only detect the occurrence of IBD but also the potential of its development and may be used as prognostic tools. More recently, stool markers were detected and used for diagnosis. Up to now, the market is still lacking a definitive, simple and non-invasive diagnostic tool. Saliva can present an alternative form of body fluids that simplify diagnostic procedures. Our hypothesis is that IBD patients have special salivary biomarkers that may be identified through salivary analysis, where later on a simple non-invasive test can be applied in the form of an easy-to-use kit, being available at the clinician's clinic for the establishment of an immediate and early diagnosis of the destructive inflammatory bowel disease.
