[Role and modalities of insulin treatment in type 2 diabetics].
BACKGROUND
The natural history of type 2 diabetes mellitus is characterized by an inescapable and gradual worsening of a decrease in insulin secretion. Thus after several years of progress, less than half of type 2 diabetic patients have good glycemic control. This explains the increase in insulin prescription to type 2 diabetic patients in France in recent years. This work's objective is to take into account recent publication data to clarify the status of and adjustments in insulin therapy.


BACKGROUND
The benefit of insulin treatment-mediated glycemic control optimization on microvascular complications is now proven. However, there is still controversy concerning macrovascular complications. Hypoglycemic risk in type 2 diabetic patients is limited and the main problem with insulin treatment is weight gain. Following failure with treatment by tablets, the most suitable treatment in terms of metabolic improvement, weight gain limitation and treatment adhesion is to add an intermediate insulin injection at bedtime. The next step remains several injections a day, with metformine addition if possible.


CONCLUSIONS
Therapeutic treatment in type 2 diabetes mellitus may become an earlier start of insulin therapy to preserve the remaining pancreatic insulin reserve. The role of brief and long-lasting insulin analogues, as well as inhaled insulin, which will soon be available, should be specified.
