Insights
Insulin glargine significantly improved glycemic control and reduced blood sugar variability in type 1 diabetes patients. This long-acting insulin analogue demonstrated effectiveness without altering basal insulin doses.
Area of Science:
- Endocrinology
- Metabolic Disorders
- Pharmacotherapy
Background:
- Type 1 diabetes mellitus (DM) management requires effective glycemic control.
- Long-term insulin analogues offer potential improvements in diabetes management.
Purpose of the Study:
- To evaluate the clinical experience with insulin glargine in type 1 diabetes patients.
- To assess the impact of insulin glargine on glycemic control and variability.
Main Methods:
- Retrospective analysis of 136 type 1 DM patients over one year.
- Monitoring of HbA1c levels at baseline and at 3, 6, and 12 months post-treatment.
- Comparison of glycemic variability using standard deviation of glucose readings before and after glargine therapy.
Main Results:
- Significant reduction in HbA1c from 7.4% to 7.1% after one year (p < 0.01).
- Marked decrease in glycemic variability (standard deviation) from 4.9 to 4.5 mmol/l (p < 0.001).
- Reduction in total daily insulin dose and bolus insulin dose, with no change in basal dose.
Conclusions:
- Insulin glargine treatment leads to significant improvements in HbA1c and glycemic variability.
- The daily dose of insulin glargine is comparable to NPH insulin.
- Insulin glargine is an effective therapeutic option for type 1 diabetes management.
Objective:
To assess the experience obtained by a diabetes centre in the treatment of patients with type 1 diabetes with the long-term insulin analogue glargin.
Patient Sample And Method:
136 patients with type 1 diabetes mellitus (DM) were evaluated on a retrospective basis for the period from March 2004 to march 2005. We monitored HbA(1c) before the treatment with glargin, after 3 months, again after 6 months, and finally after 1 year of therapy. We evaluated the effectiveness of treatment with glargin insulin based upon diabetes compensation at the start of treatment. We also compared glycaemia variability in the 6 months prior to treatment initiation and the 6 months after the application of glargin insulin, this was done using the standard glycaemia deviation obtained from the patients' glucometers. In addition we evaluated the changes in total, basal and bolus daily dose of insulin after the change in therapy.
Results:
The results were evaluated in the form of a median and the percentile of 25 and 75. Before the glargin therapy started, HbA(1c) was 7.4 (6.5-8.5)%. It decreased dramatically to 7.0 (6.2-8.1)% after 3 months of therapy (p < 0.01), to 7.2 (6.3-8.2)% after 6 months of therapy (p < 0.05), and reached the level of 7.1 (6.1-8.2)% after one year (p < 0.01). Analysis of glycemic profiles during the 6 months before and 6 months after transfer to glargin insulin therapy showed a significant decrease in the variability as evaluated by the decrease in standard deviations from the original 4.9 (4.3-5.6) mmol/l to 4.5 (3.9-5.1) mmol/l (p < 0.001). The total daily dose of insulin prior to treatment and after 6 months of therapy with glargin decreased from 44 (35-56) IU/day to 42 (34-53) IU/day (p = 0.01). There was no change in the basal dose of insulin after the change in therapy--it remained at 20 (12-28), (16-26) IU/day. The dose of bolus administered insulin decreased from 24 (18-32) to 21 (17-29) IU/day (p < 0.01).
Conclusion:
A dramatic improvement in HbA(lC) and a dramatic decrease in glycaemia variability are associated with glargin insulin treatment. The dose ofglargin insulin does not differ from that of NPH.
