Anaemia in Children Receiving Home Parenteral Nutrition: A Common Problem?

Children receiving home parenteral nutrition (HPN) are at risk of iron deficiency anaemia. Our aim was to determine the incidence of iron deficiency anaemia in paediatric HPN and efficacy of each therapeutic approach.

Retrospective data collection from children receiving HPN at a tertiary referral centre over a 12-month period (2015). Full blood count, and whenever available, ferritin and C-reactive protein were collected at least 3 times for each patient. Liver function tests were checked at the beginning and end of the study and number of blood transfusions/iron infusions recorded.

Forty-one HPN patients (61% girls; 51% motility disorder, 29% enteropathy, 20% short bowel syndrome) were identified. Eighty-three percent of children were anaemic at the beginning of the study with the number decreasing to 73% by the end. Iron deficiency anaemia was most commonly seen and treated with blood transfusion in 46% of cases and iron infusions in 29%. There was no statistical difference in the level of haemoglobin improvement between the 2 treatments (50% vs 33%, P  = 0.657) nor a significant difference in haemoglobin (g/L) level achieved. The results for both were, however, more favourable in the infusion group. Patients receiving transfusions had a significantly higher incidence of abnormal liver function compared with those who hadinfusions (93% vs 37%, P = 0.009).

Iron deficiency anaemia is common in children receiving HPN. A large proportion of patients still receive blood transfusions as first-line therapy but intravenous iron can be a suitable alternative. Treatment guidelines are required.
