Overview

Cross-sectional multicenter study observes anaemia in 18.6% of patients with inflammatory bowel disease, indicating widespread undertreatment particularly among those with active disease.

Key Points

  • To determine the prevalence, clinical associations, and therapeutic management of anaemia across a broad population of patients with inflammatory bowel disease.
  • Conducted an observational cross-sectional multicentre study across 15 participating centres during a 1-month period.
  • Enrolled 1,313 adult patients with inflammatory bowel disease, comprising Crohn's disease (59%), ulcerative colitis (39%), and unclassified disease (2%).
  • Evaluated disease activity using the Harvey-Bradshaw Index for Crohn's disease and the Simple Clinical Colitis Activity Index for ulcerative colitis.
  • Anaemia prevalence was 18.6% (95% CI 16.6–20.9; 244 of 1,313 patients), with 90% presenting with mild to moderate anaemia (mean haemoglobin 11.3 ± 0.8 g/dL) and higher frequency in females (p = 0.006).
  • Anaemia was significantly more frequent in patients with active disease compared to remission (33.6% vs. 15.6%, p < 0.001) and in those taking corticosteroids (36.8% vs. other therapies, p < 0.001), with no difference between Crohn's disease (19.1%) and ulcerative colitis (17.7%; p = 0.688).
  • Only 47% of anaemic patients received specific therapy, consisting of oral iron in 67% and intravenous iron in 41% of treated cases.
