On May 22, 2021, the Expert Board met in St. Petersburg to discuss their position on immunological aspects of determination of an adequate biological treatment sequence for inflammatory bowel diseases (IBD). The Expert Board aimed at discussion of current strategies, development of a consensus on determination of an adequate biological treatment sequence for IBD. The main topics of the agenda were the contribution of immune system to the pathophysiology of Crohn's disease, ulcerative colitis and their complications, efficacy of genetically engineered biological agents (GEBA) at various stages of IBD management. Participation of the leading Russian experts in IBD, as well as involvement of other specialties, made it possible to consider the topic by a multidisciplinary team, with an in-depth analysis of IBD pathophysiology, to better understand the course of the disease in some contradictory situation, for instance, when clinical remission is not associated with an endoscopically confirmed remission. One of the expected effects of this Expert Board meeting would be an improvement of GEBA administration in clinical practice, mostly due to the modification of clinical guidelines. This would ascertain and confirm the algorithms for GEBA administration for IBD, including the optimal treatment sequence depending on an agent’s mechanism of action and the patient profile. The clarification of the optimal GEBA sequence in the clinical guidelines could lead to more frequent GEBA administration in local medical clinics and institutions in the regions, where GEBA are used insufficiently due to little experience and absence of their precise positioning in the clinical guidelines.
