[Clinical activity and validation of the disability disc in inflammatory bowel disease].

Background: Inflammatory bowel disease (IBD) is a chronic immune-mediated pathology that causes disability and can be assessed by the simplified IBD-Disk tool, which could be conditioned by clinical activity. Objective: Associate disability with clinical activity using the IBD-DISK tool validated in patients with IBD. Material and methods: Analytical cross-sectional study in 101 outpatients and inpatients diagnosed with IBD. After obtaining informed consent, the IBD-Disk tool for disability was validated and administered, as well as its correlation with the IBD-DI. Clinical activity was assessed with the Mayo score for chronic nonspecific ulcerative colitis (CUCI) and the Harvey-Bradshaw score for Crohn's disease (CD). The association between disability and clinical activity was performed with a regression model. Results: The reliability of the IBD-Disk was > 0.900. Patients with CUCI and moderate or severe clinical activity are 8.2 times more likely to have an IBD-Disk score > 40 compared to those in remission or with mild activity. Patients with Crohn´s disease the association was OR = 2.4 (95%CI: 0.19 - 31.52). The regression model shows that clinical activity (Mayo and Harvey-Bradshaw) is the factor that most influences the disability scales (B = 4.400). Conclusions: IBD-Disk is a reliable instrument for measuring disability in CUCI and CD. Although disability does not differ significantly between CUCI and CD, clinical activity is associated with disability (IBD-Disk).
