Evaluation of Molecular Mechanisms of Non-response to Therapy in Patients With Inflammatory Bowel Disease

Inflammatory bowel diseases (IBD) represent a group of immune-mediated disorders, in which currently unidentified trigger factors drive the manifestation of chronic relapsing- remitting destructive inflammatory episodes in the gut. IBD comprise two main disease entities, ulcerati\\ie colitis (UC) and Crohn s disease (CD). The diseases differ in anatomical distribution, with continuous, uniform inflammation restricted to the colon in UC, and multifocal inflammation extended throughout the entire gastrointestinal tract from mouth to anus in CD. Clinical symptoms of IBD may include bloody stools, abdominal pain, fatigue, diarrhoea, fever and weight loss. Extra-intestinal symptoms occurring in up to 40% of patients, e.g. anaemia, skin lesions (e.g. erythema nodosum, pyoderma), arthritis and uveitis, and other complications directly related to the disease organ, such as fistula in CD are considered to reflect an overwhelming systemic inflammatory state. Disease onset typically manifests at age 15-35 years, men and women are almost equally affected. In addition, paediatric forms of IBD that often represent complex, se\\/ere monogenic forms of the disease, are seen. The incidence rates of IBD in Europe are about 6.3 (CD) and 11.8 (UC) per 100.000 persons. With growing incidence rates and overall reduced mortality the lifetime prevalence of IBD is expected to rise. The estimated lifetime prevalence of 0.3%-0.5% of the European population corresponds to estimates of 1.5-2 million pati…
