AI Article Synopsis
- The study compared insulin glargine and NPH insulin regimens in 83 Japanese patients with Type 1 diabetes over 12 months.
- Findings showed no significant changes in average HbA1c levels or daily insulin requirements between the two treatments.
- Insulin glargine resulted in fewer episodes of severe hypoglycemia and allowed most patients to switch from multiple daily injections to a single daily dose, demonstrating its benefits.
Article Abstract
Objective: To evaluate the results of treatment with an insulin glargine-based regimen as compared with those of an NPH insulin-based regimen.
Methods: We reviewed the charts of 83 Japanese patients with Type 1 diabetes treated with insulin glargine for 12 months.
Patients: Median age, 56.9 years (range, 24.6-74.8 years), mean (+/-S.D.) body mass index, 21.2 (+/-2.2) kg/m2.
Results: The average HbA1c level of the cohort was 7.8 +/- 1.2% at baseline and 7.7 +/- 1.0% at the end of the 12-month treatment (P=0.34). The average insulin requirement per day in the cohort remained unchanged after the 12-month treatment (35.0 +/- 11.6 units/day versus 35.2 +/- 11.2 units/day (P=0.58). Of the 36 patients who were receiving twice or three times daily injections of NPH insulin, 30 could be switched to a single-daily injection of insulin glargine. The frequency of severe hypoglycemia with unconsciousness became lower after switching to the insulin glargine-based regimen than during treatment with the NPH-based regimen. The average ratio of the daily usage of insulin glargine to that of total insulin after 12 months was smaller than that reported from other countries (0.34 +/- 0.09).
Conclusion: These results obtained from a larger number of patients as compared to previous Japanese studies confirm earlier reports that insulin glargine provides equivalent glycemic control to human NPH insulin, with a lower incidence of severe hypoglycemia. Thus, treatment with insulin glargine provides some benefits to Japanese patients with Type 1 diabetes.

This case report presents a rare instance of a 28-year-old female patient with insulin-induced abdominal lipodystrophy, who presented to the emergency department with symptoms of an anxiety attack triggered by body image distress. She was diagnosed with type 1 diabetes at the age of eight years. For the past 10 years, she has been using insulin glargine and insulin lispro, injecting roughly five times per day.

Characterizing and mitigating factors that impact product immunogenicity can aid in risk assessment and/or managing risk following manufacturing changes. For follow-on products that have the same indication, patient population, and active product ingredient, the residual immunogenicity risk resides predominantly on differences in product and process related impurities. Characterizing differences in innate immune modulating impurities (IIRMI), which could act as adjuvants by activating local antigen presenting cells (APCs), can inform the immunogenicity risk assessment potentially reducing the need for clinical trials.

Introduction: ONWARDS 5 evaluated the effectiveness and safety of insulin icodec (icodec) titrated with a dosing guide app (icodec with app) versus once-daily insulin analogs in insulin-naive adults with type 2 diabetes. The insulin glargine U300 (glargine U300) stratum was too small to enable a robust post hoc efficacy comparison. Augmentation methodology was applied to increase the glargine U300 group size using real-world data (RWD), to facilitate efficacy comparisons of icodec with app versus glargine U300, and to demonstrate the potential of the augmentation methodology to strengthen underpowered treatment comparisons (AUGMENT study).
