Abstract:

Objective: To investigate the effect of initiating insulin glargine (glargine: LANTUS), a once-daily basal insulin analogue, plus an educational programme, on glycaemic control and body weight in patients with type 1 diabetes in clinical practice.

Research design and methods: A retrospective analysis of the medical records of 65 patients (mean age: 40.7 ± 13.3 years) with type 1 diabetes was performed. Patients had previously been treated with NPH insulin (NPH; n = 54) or NPH insulin + lente insulin (NPH + lente; n = 11) and then received glargine once daily (bedtime), plus short-acting prandial insulin, for 30 months. Before initiation of glargine, patients participated in a diabetes educational programme and then received physician consultations throughout the study. Metabolic control, body weight and severe hypoglycaemia data were analysed at 9 and 30 months.

Results: Following initiation of glargine, patients showed a decrease in HbA_1c from 7.29 ± 1.1% to 7.06 ± 1.0%; p < 0.01 at 30 months. When the results were analysed by pre-treatment, both NPH-pre-treated and NPH+lente-pre-treated patients showed a significant reduction in HbA_1c of 0.14% and 0.82%, respectively, at 30 months (7.27 ± 1.2% to 7.13 ± 1.1% and 7.42 ± 1.2 to 6.60 ± 0.3%, respectively; p < 0.01). No change in body weight was observed in the overall group. No episodes of severe hypoglycaemia (blood glucose < 40 mg/dL [< 2.2 mmol/L] occurred.

Conclusions: In this retrospective study of medical records, patients with type 1 diabetes treated with insulin glargine over 30 months in combination with educational support and close clinical supervision decreased their HbA_1c levels without weight gain versus previous treatment with NPH insulin or insulin lente. Further studies in a larger cohort of patients would help to confirm these results.
