Despite advances in treatment, a large proportion of patients with inflammatory bowel disease (IBD) do not achieve or stay in remission even after further lines of treatment have been given. Up until now, one major obstacle has impeded our interpretation of studies focusing on patients suffering from this chronic condition: the lack of standard criteria and terminology among authors.
Under the guidance of the endpoints cluster of the International Organization for the Study of Inflammatory Bowel Disease (IOIBD), a group of experts held a consensus meeting to propose a common operative definition for “difficult-to-treat IBD.” It’s the first step to better understanding this condition and designing targeted studies and interventions.
