R.F. is a 48-year-old white man with type 1 diabetes since age 24. He was
initially seen at the Utah Diabetes Center in Salt Lake City on 15 September
2006. The patient had been treated with NPH insulin, 2 units at bedtime;
ultralente insulin, 3 units twice a day; and lispro insulin, 2-3 units at each
meal. The patient corrected elevated blood glucose levels with 1 unit of
lispro for blood glucose readings > 200 mg/dl and about 2 units of lispro
for blood glucose readings > 300 mg/dl. His hemoglobin A1c (A1C) was 9.2%,
and he described losing control of his diabetes progressively through the
years.
The patient often developed nocturnal hypoglycemia, most likely as a result
of the combination of NPH and ultralente insulins taken at bedtime, and his
blood glucose levels often dropped by 50-80 mg/dl through the night. The fear
of nocturnal hypoglycemia and the patient's inability to control postprandial
blood glucose levels were very frustrating to him. He had no evidence of
microvascular complications. His blood pressure and lipids have always been
within the normal range.
R.F.'s basal insulin regimen was changed to detemir insulin twice daily,
and he was also given an insulin-to-carbohydrate ratio to determine lispro
doses at mealtimes and a correction scale to aggressively correct
hyperglycemia. He also received intensive diabetes education. By 7 April 2007,
his A1C was 7.8%, and he had gained much more confidence as his blood . . . [Full Text of this Article]
