INTRODUCTION: Anemia is a frequent complication in patients with inflammatory bowel disease (IBD). The inflammation observed in IBD negatively impact absorption of iron. This could lead to increased hospitalizations, affect growth and development, and decrease overall quality of life. This is especially pronounced in the pediatric population. The screening and treatment of iron deficiency anemia (IDA) varies between centers, and as a result, roughly 40-60% of pediatric IBD patients are iron deficient.
OBJECTIVES: The objective of this study is to assess the efficacy and safety profile of intravenous and enteral iron therapy in a population of iron deficient patients with IBD. The secondary aim of this study is to determine if oral or intravenous iron therapy can improve hematologic and iron parameters. We will also examine the longitudinal changes in gastrointestinal (GI) symptoms and quality of life in patients receiving oral and intravenous iron supplementation.
METHODS: We conducted a prospective cohort study in pediatric patients with IBD admitted to the inpatient GI service at Boston Children’s Hospital from 09/05/2017 to 03/05/2018. Forty-six IBD patients were screened, and twenty-nine (63%) were identified as iron deficient and were consented for data collection through chart review and administration of the IMPACT-III quality of life questionnaire.
RESULTS: Out of the twenty-nine IBD patients, eighteen (62%) received intravenous iron, seven (24%) received oral iron, and four (14%) were untreated and served as controls. The mean change in hemoglobin in patients receiving parenteral, oral, or no iron therapy was 1.6g/dl±0.5, 1.1g/dl±0.4, and 0.2g/dl±0.5, respectively. The change in hemoglobin was significant between the parenteral and oral iron group (P<0.05). The mean change in health-related quality of life scores in patients receiving parenteral or oral iron therapy was 11.6±11.4 and 3.8l±7.5, respectively.
CONCLUSION: Our study demonstrates that intravenous iron therapy was more efficacious than oral iron in improving hematologic and iron parameters in IBD patients. This improvement was concomitant with higher scores on the IMPACT-III quality of life questionnaire, suggesting that iron supplementation improves health-related quality of life in IBD patients with iron deficiency anemia.
