Continuous subcutaneous insulin infusion benefits quality of life in preschool-age children with type 1 diabetes mellitus

Abstract

To compare medical, nutritional, and psychosocial outcomes of continuous subcutaneous insulin infusion (CSII) therapy and multiple daily insulin injections (MDI) in preschoolers with type 1 diabetes mellitus (T1DM) in a randomized controlled trial. Sixteen children (mean age 4.4 +/- 0.7 yr, range 3.1-5.3 yr) with T1DM were randomly assigned to CSII or MDI. Hemoglobin A1c (HbA1c) was measured monthly for 6 months. Glucose variability was measured at baseline and at 6 months using continuous blood glucose sensing. Quality of life, adverse events, and nutrition information were assessed. Parents of the CSII group reported a significant decrease in diabetes-related worry, while parents of the MDI group reported an increased frequency of stress associated with their child's medical care. Mean HbA1c levels from baseline (CSII 8.3 +/- 1.4%, MDI 8.0 +/- 0.8%) to 6 months (CSII 8.4 +/- 0.8%, MDI 8.2 +/- 0.4%) remained stable, and group differences were not significant. There were no significant group differences in duration of hypo- or hyperglycemic events or frequency of adverse events. For young children with T1DM, CSII therapy is comparable to MDI therapy with regard to glucose control but is associated with higher treatment satisfaction and improved quality of life.
