Clinical and genetic predictors of drug dependency in inflammatory bowel disease
Ďuricová, Dana ; Lukáš, Milan (advisor) ; Keil, Radan (referee) ; Špičák, Julius (referee)
IN ENGLISH Drug dependency in inflammatory bowel disease (IBD), Crohn's disease (CD) and ulcerative colitis (UC), is a specific disease phenotype which determines disease prognosis and hence may be used as a prognostic marker for treatment management. Drug dependency in IBD has been well described in corticosteroid treatment and recently also in infliximab (IFX) therapy. The aims of this thesis were: 1) to assess the occurrence of IFX dependency in paediatric and adult patients with CD; further to search for clinical and genetic predictors of IFX outcome and to evaluate the impact of IFX dependency on surgical rate; 2) to assess in CD patients the outcome of the first course of 5-ASA monotherapy with emphasis on 5-ASA dependency and to define clinical predictors of 5-ASA treatment outcome. We found that 66% of children and 29% of adults with CD became IFX dependent. The high frequency in paediatrics is in agreement with previously published studies, while the finding in adult patients indicates a lower rate of IFX dependency in the only study to date. Perianal disease and no bowel surgery prior to IFX start were predicative of IFX dependency in paediatric patients. In adult cohort, 2 genetic variants LTA c.207 A>G and CASP9 c.93 C>T were associated with IFX outcome, whereas no relevant clinical...
