简要总结
Basal insulin is widely used in older patients with diabetes. Human insulin Neutral Protamine Hagedorn (NPH) has been proposed as basal insulin in older (75 years or older) frail and dependent patients due to its shorter action. However, no study has analysed the glycaemic profile in elderly subjects according to the basal insulin used, particularly in frail or disabled patients.
The aim of this study is to measure intra-day glycaemic variability according basal insulin (human NPH or long acting analogues) in older (75 and older) frail or disabled patients with diabetes using continuous glucose monitoring system.
详细描述
Increased prevalence of diabetes mellitus is in large part related to ageing: in France in 2009, 26% of patients with diabetes were 75 older or over. Moreover, diabetes prevalence is particularly high among institutionalized subjects with more than half of them treated with insulin.
Diabetes is source of activities limitations and participation restriction from the early stages of the disease and is responsible for 10% of direct health costs, with higher costs for older patients or insulin treated patients.
Older patients with diabetes may be robust (fully independent), frail or disabled. Studies with patients of 75 years or older included mainly robust subjects. Nevertheless older patients with diabetes are more frequently frail and a large proportion have a different metabolic profile than younger ones: they are leaner and present more often with beta-cellular insufficiency. Frail or dependent patients may also have different nutritional status than robust ones. Thus, this is difficult to extrapolate what is known about glycaemic profile in robust and young older (65-74 years old) insulin-treated patients to frail and dependent older ones (>74 years).
Continuous blood glucose monitoring systems give the opportunity to measure around the day the blood glucose variations in real-life and particularly nocturnal hypoglycaemia for these patients treated with various types of basal insulins.
