Insulin glargine maintains equivalent glycemic control and better lipometabolic control than NPH insulin in type 1 diabetes patients who missed a meal.

摘要

Our goal was to investigate blood glucose and lipometabolism control in type 1 diabetes patients who missed breakfast and the accompanying insulin injection of NPH insulin (NPH) or insulin glargine (glargine) as part of a basal-bolus regimen. This was a multi-center, open-label, controlled study in adults (> or =18 years) with HbA (1c)< or =11.5% on insulin therapy with NPH as basal insulin. Patients were randomized to receive prandial insulin plus either bedtime glargine (n=28) or NPH (n=32). Insulin was titrated to target fasting blood glucose levels 80-130 mg/dl at 06:00-07:00. Patients had no intake of insulin or food between 22:00 and 12:00 the next day. The change in blood glucose levels (07:00-11:00) was similar (27.5 mg/dl vs. 35.4 mg/dl), but the mean blood glucose level was higher with glargine vs. NPH at 22:00 (158.2 mg/dl vs. 130.2 mg/dl). During the period without insulin or food intake, blood glucose decreased with glargine (-25.8 mg/dl) and increased with NPH (+9.1 mg/dl; p=0.0284). Nonesterified fatty acid (07:00 and 09:00-12:00) and beta-hydroxybutyrate (07:00 and 10:00-12:00) levels were lower with glargine vs. NPH (both p<0.05). For patients who miss a morning meal, glargine is associated with maintained glycemic and lipometabolic control compared with NPH insulin.
