Abstract
Background and aims: A multicentre, retrospective, non-interventional, patient chart review study was conducted to investigate deep (DR) and histological remission rates during maintenance therapy with biological agents in inflammatory bowel disease (IBD). Methods: We reviewed clinical, endoscopic, and histological findings, and laboratory markers such as C-reactive protein (CRP) and faecal calprotectin (FC) on average of nine years after the initiation of anti-TNF-therapy. DR was defined as no clinical symptoms (The physicians' global assessment scores; PGA = 0) with endoscopic remission (the Simple Endoscopic Score for Crohn's Disease [SES-CD] <= 2 or Mayo endoscopic subscore <= 1). Histological activity was defined as normal if only architectural alterations without cellularity changes occurred. Results: Of 117 IBD patients on maintenance therapy, 72 (62%; CD n = 55 [56%], UC n = 17 [85%]) patients were in DR. Of patients in DR, 76% were also in histological remission. 77% of patients remained on initiated biological treatment. UC patients achieved DR significantly more often than CD patients (p = .016). Both median CRP and FC levels were significantly lower in patients with DR. Conclusion: Reassuringly, almost two thirds of the IBD patients on maintenance therapy with biological agents maintained DR in the long-term, and more than two thirds of patients in DR achieved also histological remission. CD patients in DR had fewer surgical operations due to CD than patients not achieving DR.
