Continuous subcutaneous insulin infusion in children

Insulin-dependent diabetes mellitus usually presents in childhood. Since it is generally accepted that persisting metabolic derangements contribute to the development of micro- and macrovascular complications, a primary aim of the management of children with diabetes is to achieve near normalization of metabolism. In adults continuous subcutaneous insulin infusion (CSII) has been used to optimize control. Despite a reluctance amongst paediatricians to use CSII in children, several studies with pumps have been performed in adolescents. The results of these studies are contradictory with respect to acceptability and achieved metabolic control. Thus, some authors report a near normalization of blood glucose concentrations, whereas others only find a temporary improvement. Patient selection seems to account for many of these differences. This suggests that methods ought to be developed to predict success or failure of CSII in a particular adolescent patient. For diabetic toddlers with their age-specific problems CSII may be a therapy of choice. So far, good acceptability and improved metabolic control are reported in this group. More studies are needed to confirm this. It is important that the diabetic clinic as well as the patient is organized to a high standard before starting CSII. Home blood glucose measurements, education, and a 24-h telephone service are essential factors for the management of diabetic children, treated conventionally or with CSII.
