Abstract

OBJECTIVE:

To describe our clinical experience with U500 insulin in insulin-resistant patients, including change in glucose control, body weight, insulin dose, and hypoglycemic episodes.

METHODS:

In September 2010, we undertook a retrospective chart review of patients who had U500 insulin in their medication list in the preceding 2 years who were treated in the endocrinology section at Dartmouth Hitchcock Medical Center. Glycosylated hemoglobin (A1C), body weight, and insulin dosage were documented before U500 insulin introduction, after 6 months of U500 insulin use, and at the last clinic visit when the patient was still taking U500 insulin. Hypoglycemic episodes and number of daily injections were recorded.

RESULTS:

Records of 53 patients were analyzed, one of the largest reports of U500 insulin use published to date. The mean A1C level decreased from 10.1% before U500 insulin was initiated to 9.1% after 6 months of U500 use to 8.6% at the last follow-up visit (mean follow-up was 36.6 ± 24 months). At the last charted visit, body weight increased by a mean of 6.8 kg and insulin dosage increased by a mean of 0.44 units/kg. We observed a significant increase in the number of nonsevere hypoglycemic episodes and a decrease in the number of daily injections.

CONCLUSION:

Patients with uncontrolled, severely insulin-resistant diabetes can be satisfactorily treated with U500 insulin with the potential to improve glycemic control. An increase in body weight, insulin dosage, and the number of nonsevere hypoglycemic episodes was observed.
