Summary

Twice-daily Neutral Protamine Hagedorn (NPH) insulin therapy resulted in better glucose control and fewer hypoglycemic episodes compared to once-daily ultralente insulin in type 2 diabetes patients. Patients also reported higher treatment satisfaction with NPH insulin.

Area of Science:

  • Endocrinology
  • Metabolic Diseases
  • Pharmacology

Background:

  • Type 2 diabetes management often involves insulin therapy.
  • Optimizing insulin regimens is crucial for glycemic control and patient well-being.
  • Comparing different insulin formulations and dosing frequencies can improve treatment outcomes.

Purpose of the Study:

  • To directly compare the efficacy of once-daily ultralente insulin versus twice-daily Neutral Protamine Hagedorn (NPH) insulin.
  • To assess rates of hypoglycemia and metabolic control (HbA1c) in type 2 diabetes patients.
  • To evaluate patient treatment satisfaction and quality of life with each insulin regimen.

Main Methods:

  • A crossover study involving 79 type 2 diabetes patients.
  • Patients received either NPH or ultralente insulin for two 6-month periods.

  • Specialist nurses managed dosage adjustments using a protocol.

    • Main Results:

    • NPH insulin therapy achieved significantly lower HbA1c levels compared to ultralente insulin.
    • Ultralente insulin was associated with higher evening glucose levels and a greater number of hypoglycemic episodes, including those requiring third-party assistance.
    • Treatment satisfaction scores significantly improved with NPH insulin and decreased with ultralente insulin.

    Conclusions:

    • Twice-daily NPH insulin offers superior glucose control and a lower risk of hypoglycemia compared to once-daily ultralente insulin in type 2 diabetes.
    • NPH insulin therapy leads to greater patient treatment satisfaction.
    • These findings support the use of twice-daily NPH insulin for improved management of type 2 diabetes.
