ABSTRACT
BACKGROUND: Screening for iron deficiency anemia (IDA) is important in managing pediatric patients with inflammatory bowel disease (IBD). Concerns related to adverse reactions may contribute to a reluctance to prescribe intravenous (IV) iron to treat IDA in this population. AIM: To track the efficacy and safety of IV iron therapy in treating IDA in pediatric IBD patients admitted to our center. METHODS: A longitudinal observational cohort study was performed on 236 consecutive pediatric patients admitted to our tertiary IBD care center between September 2017 and December 2019. 92 patients met study criteria for IDA, of which 57 received IV iron, 17 received oral iron, and 18 were discharged prior to receiving iron therapy. RESULTS: Patients treated with IV iron during their hospitalization experienced a significant increase of 1.9 (± 0.2) g/dL in mean (± SE) hemoglobin (Hb) concentration by the first ambulatory follow-up, compared to patients who received oral iron 0.8 (± 0.3) g/dL or no iron 0.8 (± 0.3) g/dL (P = 0.03). One out of 57 (1.8%) patients that received IV iron therapy experienced an adverse reaction. CONCLUSION: Our findings demonstrate that treatment with IV iron therapy is safe and efficacious in improving Hb and iron levels in pediatric patients with IDA and active IBD.
ABSTRACT
BACKGROUND: The 2003 Joint Task Force on Practice Parameters recommended standardizing allergen subcutaneous immunotherapy (SCIT). Data from longitudinal surveillance survey in North America reported a systemic reaction (SR) rate of 0.1% to 0.2% of injection visits. The rate of SR to standardized SCIT in pediatric patients has not been well evaluated. OBJECTIVE: The objective of this study was to evaluate the rate of SRs to standardized SCIT in pediatric patients aged 5 to 18 years in a single tertiary care center in the United States. METHODS: A retrospective chart review was conducted in 2 groups: group 1 started SCIT within a period extending from January 2009 to June 2012, whereas group 2 started SCIT within a period extending from January 2013 to June 2016. The protocol was modified in group 2 such that updosing and maintenance doses were adjusted in the spring for tree and grass pollen and in the fall for weed pollen. RESULTS: There were a total of 128 patients in group 1 and 118 patients in group 2. The rate of SR was 0.429% in group 1 and 0.364% in group 2, which was not significant. There was no difference in the severity of SR in the 2 groups with no-fatal or near-fatal SR noted. Asthma was a significant risk factor in the younger age subgroup aged 5 to 11 years. CONCLUSIONS: Standardized SCIT appears to be associated with an SR rate of 0.429% to 0.364% of visits in pediatric patients. Protocol modification did not lead to a significant drop in SR. Larger multicenter studies are required to further evaluate the rate of SRs from standardized SCIT.
