Risk of ketosis during intensive insulin therapy in pre-school-age diabetic children

P Brambilla, E Artavia-Loria, JL Chaussain and PF Bougneres

The risk of ketosis and its relationship to the mode of insulin therapy were studied in a subset of pre-school-age diabetic children. These five children, who initially responded poorly to standard in-hospital diabetes management, were selected for a program of intensified therapy directed at achieving more stable blood glucose control. Optimized conventional therapy was first employed for 16 +/- 5 mo and did not improve substantially blood glucose level or stability. During this period, there was an average of almost one episode of ketonuria per patient per month, and three diabetic ketoacidosis episodes were observed. Because of its limited efficacy, the treatment was then changed to continuous subcutaneous insulin infusion. This mode of therapy had a rapid favorable effect on blood glucose control, with no concomitant increase of the frequencies of ketonuria or diabetic ketoacidosis, most of which occurred during the first months of insulin pump therapy. Deliberate cessation of either conventional or subcutaneous insulin infusion therapy for 7 h under close in-hospital control resulted in similar metabolic changes: a slight nonconstant increase of blood glucose, and an abrupt rise of blood 3-hydroxybutyrate to 3 mM, with massive ketonuria. The management of these young diabetic children with insulin pump therapy was thus not associated with an increased frequency or an accelerated rate of development of ketosis. However, the possible failures originating from the infusing device and the rapid increase of ketosis in young ages require special vigilance from the parents, based on twice-daily urine testing for ketones and appropriate insulin supplementation.
