Initiating insulin in primary care--the role of modern premixed formulations

Insulinization: A promising strategy for the treatment of type 2 diabetes mellitus

The aim of the present study was to assess the efficiency of the long-term use of continuous subcutaneous insulin infusion (CSII), a novel regimen known as insulinization, for the treatment of type 2 diabetes mellitus. A total of 150 subjects who fulfilled the diagnostic criteria for type 2 diabetes were included in the study. The patients were divided into eight groups according to the treatment regimens they received and were monitored for 3 months. Insulin doses were adjusted to optimize glycemic control with the simplest possible insulin regimen. The outcomes studied included the time required for glycemic control and insulin dose reduction, the total daily insulin dose, the ratio of patients not requiring the administration of oral antidiabetic drugs (OADs), the rate of hypoglycemia, and hemoglobin A1c (HbA1c) and fasting plasma insulin (FinS) levels. Patients receiving insulinization required less time to achieve optimal glycemic control and insulin decrement compared with patients receiving other treatments. The total daily insulin dose for patients receiving insulinization therapy was 0.23±0.07 U/kg/day, which was lower than that in any other group. In patients receiving insulinization, the ratio of patients that did not require OADs (43.3%) and the concentration of FinS A were higher than those in the other groups. Furthermore, insulinization resulted in a greater reduction in HbA1c levels, as well as a reduced incidence of severe hypoglycemia. Insulinization may mimic physiological insulin secretion more effectively than other therapies. This regimen is more efficient and reduces the incidence of hypoglycemia in patients with type 2 diabetes, indicating that it is likely to be a promising treatment strategy for the disease.

Intensifying treatment of type 2 diabetes mellitus: adding insulin

Treatment for patients with type 2 diabetes mellitus is typically initiated with a combination of lifestyle modification and oral drugs. This treatment provides sustained glycemic control in some patients, but many others require administration of insulin as their disease progresses and pancreatic β cells are lost. One of the most important points in long-term care for patients with type 2 diabetes is the transition to insulin therapy. Health care professionals must choose the most appropriate insulin preparations for management of patients with type 2 diabetes who cannot achieve treatment goals by using other therapies. These include basal, premixed, and basal-bolus insulin regimens. In addition, there are multiple approaches to initiation of insulin treatment, including addition of basal insulin to oral drugs, switching patients to a premixed insulin formulation, or basal-bolus treatment. The pharmacist can play a key role in the transition to insulin therapy by providing education and assisting in day-to-day management of patients with type 2 diabetes who require insulin for intensification of treatment.

Insulin detemir improves glycaemic control with less hypoglycaemia and no weight gain: 52-week data from the PREDICTIVE study in a cohort of French patients with type 1 or type 2 diabetes

AIM

PREDICTIVE (an ongoing multinational observational study) provides an opportunity to explore the impact of insulin detemir use in routine clinical practice. Here, we report on long-term (52-week) data from a French cohort of patients (n=1772), comprising 643 with type 1 diabetes and 1129 with type 2 diabetes.

METHODS

Patients were prescribed insulin detemir at their physician's discretion and assessed at various visits (baseline, 12 weeks, 26 weeks and 52 weeks). The primary endpoint was the frequency of serious adverse drug reactions, including major hypoglycaemia. Secondary endpoints included minor and nocturnal hypoglycaemia, glycaemic control (HbA(1c), fasting blood glucose and variability of fasting blood glucose) and weight change.

RESULTS

The incidence of serious adverse drug reactions was low throughout the study, seen in 10 patients with type 1 diabetes (14 events, 1.6%) and seven with type 2 diabetes (seven events, 0.6%). In both type 1 and type 2 diabetes cohorts, the overall minor and nocturnal hypoglycaemic events were reduced from baseline (P<0.001), with no clinically significant changes in weight from baseline to endpoint. After 52 weeks of treatment with insulin detemir, glycaemic control improved, with reductions in: HbA(1c), by -0.6% and -0.8% in type 1 and type 2 diabetes patients, respectively; fasting blood glucose, by -1.4mmol/L and -1.9mmol/L respectively; and FBG variability, by -0.8mmol/L and -0.3mmol/L, respectively (P<0.0001 for all).

CONCLUSION

Patients treated with insulin detemir in a clinical healthcare setting improved their glycaemic control with no increases in hypoglycaemia, adverse events or weight compared with baseline.
