USE OF THE PEN DELIVERY SYSTEM FOR INTENSIVE INSULIN THERAPY IN COLLEGE-AGE STUDENTS WITH TYPE-I DIABETES

The present report describes our experience with 16 adolescents and young adults with insulin-dependent diabetes mellitus (IDDM; Type I) who switched from two injections of insulin per day to the NovolinPen and four insulin injections a day. Their mean age at the initiation of therapy was 19.2 years with a duration of diabetes of 8.9 years. Sixteen random computer-matched (for age, sex, and duration of diabetes) controls who remained on two insulin injections a day were evaluated for comparison. Most subjects were preparing to leave home for college. After a minimum of 1 year of using the pen, the mean weight gain of the test subjects was significantly greater (P < .05) than for the computer-matched controls. Glycemic control, as monitored by mean HbA1c values, were similar for the NovolinPen and the control groups (10.8 versus 10.9, respectively) after almost 2 years. The main advantage to the pen expressed by the users was a sense of freedom of lifestyle.
