Post-prandial insulin lispro vs. human regular insulin in prepubertal children with Type 1 diabetes mellitus.

Abstract

AIMS:

To study whether post-prandial insulin lispro (PL) could be used as a part of insulin therapy instead of premeal human regular insulin (HR) in prepubertal children with Type 1 diabetes mellitus (Type 1 DM).

PATIENTS AND METHODS:

In this open, randomized cross-over study patients used either PL or HR at breakfast and at dinner. After a 1-month screening period, patients were randomized to treatment with PL or HR for 3 months and then they crossed over to the other insulin for an additional 3 months. The patients were 24 prepubertal children with Type 1 DM (median age 6.2 years, duration of diabetes 37 months). Home monitoring of 1-day glucose profiles at meals (premeal, 1 h and 2 h after breakfast and after dinner) and HbA1c were measured before randomization, before cross-over, and at the last visit. Data on hypoglycaemic episodes were collected at each of the seven visits. The variables were compared between the two treatments.

RESULTS:

Of the patients 22/24 completed the study. There were no major differences in the glucose excursions between PL and HR after breakfast (mean +/- SD: 1-h PL 3.7 +/- 4.7 vs. HR 2.9 +/- 3.9 mmol/l, P = 0.3; 2-h -0.9 +/- 5.4 vs. 0.3 +/- 4.5 mmol/l, P = 0.2, respectively) or after dinner (1-h PL -2.5 +/- 4.8 vs. HR -0.4 +/- 3.7 mmol/l, P = 0.07, 2-h -4.1 +/- 5.2 vs. -0.7 +/- 5.0 mmol/l, P = 0.05, respectively). Mean change of HbA1c was similar in both treatment groups (PL 0.2 +/- 0.8% vs. HR -0.4 +/- 0.7%, P = 0.1). The frequency of hypoglycaemic episodes was 4.9 per patient per month during treatment with PL, and 4.4 during HR (P = 0.3).

CONCLUSION:

Treatment with post-prandial lispro as a meal insulin is as effective and safe as traditional treatment with regular insulin in young children.
