The effect of continuous subcutaneous insulin infusion (CSII) on glycaemic control and insulin binding to erythrocytes was studied in six diabetic patients. A marked improvement in blood glucose control during CSII was observed in these patients previously on conventional therapy. Specific 125I-insulin binding to erythrocytes of the diabetics before the institution of CSII was significantly lower than that of age-, weight- and sex-matched nondiabetic subjects, 6.5 ± 0.1% vs. 9.8 ± 0.3% (P < 0.05). After 4-6 months of CSII, insulin binding was restored to normal levels. This normalization in insulin binding to erythrocytes of patients on CSII was due to a 35% increase in active binding sites, together with a small change in binding affinity.
