    Background & ObjectivesConventionally, biphasic human insulin (30/70, BHI) is used twice daily for the management of patients with diabetes. However, this regimen is suboptimal to control post-lunch and/or pre-dinner hyperglycaemia in some patients. This study was undertaken to compare the efficacy and safety of thrice-daily biphasic human insulin (30/70, BHI) versus basal detemir and bolus aspart (BB) in patients with poorly controlled type 2 diabetes mellitus (T2DM).MethodsIn this open labelled randomized pilot study, 50 patients with uncontrolled T2DM on twice-daily BHI and insulin sensitizers were randomized either to BHI thrice-daily or BB regimen. HbA1c, six point plasma glucose profile, increment in insulin dose, weight gain, hypoglycaemic episodes and cost were compared between the two treatment groups at the end of 12 wk.ResultsMean HbA l c (± SD) decreased from 9.0 ± 0.9 per cent at randomization to 7.9 ± 0.8 per cent in BHI (P<0.001) and from 9.4 ± 1.3 to 8.2 ± 1.0 per cent in BB regimen (P<0.001) after 12 wk of treatment. The mean (± SEM) weight gain in patients in the BHI regimen was 1.5 ± 0.33 kg compared to 1.4 ± 0.34 kg in the BB regimen. Insulin dose increment at 12 wk was significantly more in the BB regimen 0.46 ± 0.32 U/kg/day compared to 0.15 ± 0.21 U/kg/day in the BHI regimen (P<0.001). The incidence of major as well as minor hypoglycaemic episodes was not different in both the regimen. The BB regimen was more expensive than the BHI regimen (P<0.001).Interpretation & ConclusionsThe thrice daily biphasic human insulin regimen is non-inferior to the basal bolus insulin analogue regimen in terms efficacy and safety in patients with poorly controlled T2DM. However, these data require further substantiation in large long term prospective studies.
