Study Overview
Brief Summary
Sleep apnea syndrome is strongly associated to type 2 diabet, partly and this is partly due to obesity. Treatment of sleep apnea may improve hypertension, cardiovascular risk and in some studies diabetes status. Few data are available for type 1 diabetes but suggest that the prevalence of sleep apnea syndrome may be high. We plan to compare the prevalence of sleep apnea syndrome assessed by polysomnography in a sample of type 1 diabetic patients and a control group matched by age, gender and body mass index. The secondary objective is to determine if the presence of an autonomic neuropathy or poorly controlled diabetes (assessed by glycosylated haemoglobin) may or not contribute to the presence of sleep apnea in the diabetic group.
Detailed Description
Diagnostic protocol designed to evaluate if if sleep apnea syndrome is more frequent in type 1 diabetes than in general population and therefore deserves to be more systematically suspected and actively diagnosed in this patients. Sleep apnea syndrome is a heavy burden as a matter of quality of life: it is responsible for fatigue, diurnal sleepiness, cognitive impairment, poor and /or non restorative sleep, morning headaches, depressive mood...Adequate treatment provides a rapid and, most of the time, complete relief of these symptoms.
On an other hand, Sleep Apnea is and independent risk factor for cardiovascular mortality and morbidity in young and middle aged subjects, also reversed by treatment. It might be therefore important for type 1 diabetic patients who have already an increased cardiovascular risk to be properly diagnosed for sleep apnea. A systematic screening for sleep apnea is already recommended for patients with type 2 diabetes by experts.
A secondary objective is to determine if the presence of a sleep apnea syndrome in type 1 diabetic patients is associated to an autonomic neuropathy, a poor glycemic control , a poorer quality of life , a poorer quality of sleep, more severe cardiovascular consequences and biological impairment.

Outcomes
Primary Outcomes
Compare the prevalence of sleep apnea syndrome by polysomnography between type 1 diabetic patients and healthy volunteers
Time Frame: 3 months
Determine if prevalence of the sleep apnea syndrome is more raised at the patient's diabetics of type 1 (DT1) than in the general population and to collect elements to specify the determiners of this association (presence of an autonomous neuropathy and glycemic balance). sleep apnea syndrome as defined by the International Classification of Sleep Disorders 2
Secondary Outcomes
- Precise if glycemic balance as defined by glycosylated hemoglobin<7% during the last three months is associated or not to sleep apnea syndrome(3 months)
- Precise if the presence of an autonomic neuropathy (positive at 2 tests) is associated or not to sleep apnea syndrome(3 months)
- Compare the patients with or without sleep apnea regarding consequences especially cardiovascular markers and coagulation factors(3 months)
- Precise clinical symptoms in DT1 patients with Sleep apnea syndrome(3 months)
- Determine if the presence of sleep apnea syndrome has an impact upon quality of life and diabetes complications, micro or macroangiopathy(3 months)
