Search for the most practical regular/NPH mixtures for type I diabetic patients

Area of Science:

• Endocrinology
• Metabolic Disorders
• Pharmacology

Background:

• Type I diabetes requires careful blood glucose management.
• Human insulin mixtures offer therapeutic options for glycemic control.

Purpose of the Study:

• To evaluate the efficacy of different human insulin mixtures (regular: NPH) in type I diabetic patients.
• To determine the optimal ratio of regular to NPH insulin for glycemic control.
• To assess the impact of meal timing on postprandial glucose excursions.

Main Methods:

• Randomized trial involving 9 type I diabetic patients.
• Administration of human insulin mixtures with varying regular insulin percentages (10%, 15%, 20%).
• Monitoring of blood glucose levels and assessment of postprandial glucose excursions.

Main Results:

• The 15:85% (regular: NPH) insulin mixture achieved a mean blood glucose range of 70-150 mg/dl.
• Significant differences in glycemic control were observed between 10:90%, 15:85%, and 20:80% mixtures at specific time points.
• Extending the pre-breakfast interval from 30 to 45 minutes mitigated postprandial glucose spikes for 15:85% and 20:80% mixtures, but not the 10:90% mixture.

Conclusions:

• The 15:85% human insulin mixture shows promise for managing type I diabetes.
• Adjusting the timing of insulin administration relative to meals can significantly impact glycemic control.
• Further research into optimal insulin ratios and administration timing is warranted for improved diabetes care.
