Context and objective: Insulin glargine (Lantus (R)) stimulates growth of MCF-7 cells stronger than human insulin. We investigated if serum from diabetic patients treated with glargine versus human insulin may display a similar effect.Methods: Pairs of serum samples from 31 C-peptide negative type-1 diabetic patients were investigated. In cross-over fashion, 23 patients were treated with glargine plus rapid-acting insulin analogues, and similar doses of human NPH and rapid-acting insulin. For comparison, eight patients were treated with insulin detemir (Levemir (R)) and human NPH. MCF-7 cells were incubated with 10% serum and proliferation was assessed after 72 hours.Results: Serum containing insulin glargine was 1.11(95% CI 1.05-1.18) fold more mitogenic than human insulin-containing serum (p < 0.005); mitogenicity of serum containing detemir was 0.99(95% CI 0.98-1.02) fold that of human insulin-containing serum.Conclusion: The serum of diabetic patients was slightly stronger mitogenic when using glargine as compared to human insulin or detemir for treatment.
