P580 Iron deficiency anaemia and quality of life in Inflammatory Bowel Disease: Prospective cohort study of ferric derisomaltose on quality of life and work productivity in patients with IBD

Abstract

Abstract Background Iron-deficiency anaemia is a frequent complication of inflammatory bowel disease (IBD), affecting approximately 10% of patients at any one time. Quality of life scores in patients with IBD and anaemia are similar to those reported in malignancy. ECCO guidelines recommend assessment and treatment of iron deficiency anaemia, with a goal of normalising haemoglobin and iron stores. Methods We conducted a prospective observational cohort study of patients with IBD being treated for iron deficiency anaemia with ferric derisomaltose. Patients were included who were anaemic as per World Health Organisation criteria with a ferritin of <30 µg/L and/or a transferrin saturation of <18%. Variables collected included haematological parameters, the 12-item Short Form survey (SF-12) as a generic health-related quality of life measure, the Work Productivity and Activity Impairment (WPAI) questionnaire and the Short Inflammatory Bowel Disease Questionnaire (SIBDQ) as a disease-specific quality of life measure. Patients were assessed at baseline, 12 weeks and 52 weeks. We present here the outcomes at week 12. Comparative statistics have been conducted using Wilcoxon signed rank tests and Pearson’s correlation coefficient. Results We recruited 124 patients given between 700 and 1900 mg of ferric derisomaltose, each as a single infusion. Of these, 60% (74/124) were female and the median age was 43 years (IQR 31 – 58). Just under half (46%) of participants had Crohn’s disease, the remainder had ulcerative colitis (49%) or IBD unclassified (5%). Median (IQR) baseline haemoglobin was 114 (109 – 123) g/L in men and 110 (104 – 116) g/L in women. By week 12, haemoglobin, ferritin, SIBDQ, the WPAI, and both the mental and physical component scores of the SF-12 had improved significantly (all p values <0.0001; see Figure 1). Change in the physical score of SF-12 correlated positively with change in haemoglobin (r = 0.38, p<0.0001), while the change in WPAI correlated negatively with change in haemoglobin (r = -0.30, p=0.013). Conclusion Treatment with intravenous ferric derisomaltose in patients with iron deficiency anaemia and IBD was associated with significant improvements in haematological, work productivity, and quality of life parameters.
