Multicenter, open-label, non-randomized, non-interventional observational study of safety of treatment initiation with a biphasic insulin aspart.

ABSTRACT

BACKGROUND: Type 2 diabetes mellitus is characterized by hyperglycaemia. Incidence and progression of microvascular complications have been shown to undergo reduction with lowered glucose levels. METHODS: This is an open-label, non-randomized, non-interventional, observational study of safety and efficacy of BiAsp 30, enrolling 2223 patients with type 2 diabetes mellitus. Patients previously treated with oral antidiabetic drugs and/or human insulin were recruited, provided they had been hospitalized for at least 3 days. Data were collected during a single multi-stage visit lasting up to 6 days, during the patient's hospitalization period. A mild hypoglycaemic episode was defined as blood glucose measurement < 56 mg/dL (3.1 mmol/L). A severe hypoglycaemia was hypoglycaemic episode requiring assistance of another person. RESULTS: The total number of hypoglycaemic episodes decreased over time of follow-up. The intensity of severe hypoglycaemic episodes decreased by almost a third from day to day (IRR = 0.64, 95%, p < 0.001). However, intensity of mild hypoglycaemic episodes was the same over the subsequent days of follow-up (IRR = 0.97, p > 0.1). Mean blood glucose concentration decreased from 202.0 mg/dL to 157.8 mg/dL after 3 days and to 138.3 mg/dL after 6 days (p < 0.001). CONCLUSION: This study highlights the safety, efficacy and ease of initiation of insulin BiAsp 30 therapy for treatment of type 2 diabetes mellitus.
