20 Insulin resistance is associated with abdominal obesity

21 Fat overflow hypothesis Caloric intake Saturated fat SC fat Free fatty acids Abdominal fat Free fatty acids adipokines Intrahepatic fat Intramyocellular fat Insulin resistance Beta-cell dysfunction

22 Why??

23 The usual suspects.. Ageing population Urbanization Obesogenic cultures Change in lifestyle Change in psychosocial environment?

45 Obstructive sleep apnea in diabetes 305 Americans referred for sleep AHEAD obese (BMI 36.5 kg/m2) Foster et al, Diab Care no moderate AHI: < >30 86 % 279 Americans unselected obese (BMI 33.5 kg/m2) Einhorn et al, Endocrine Prac %

46 OSAID Obstructive sleep apnea in diabetes Aim: To estimate the prevalence of OSA in type 2 diabetes patients in Denmark Patients: Unselected clinic based cohort of all newly referred patients with type 2 diabetes Design: 3 step approach Collaboration between: - Patientcare center at Steno Diabetes Center - Clinical Research Unit at SDC - Respiration Center East, Rigshospitalet

47 OSAID 3 step approach: 1) Berlin questionnaire 2) ApneaLink 3) Referral for sleep clinic

48 OSAID status (9.marts 2011) 143 Berlin questionnaires 57 without symptoms of OSA 77 ApneaLink handed out 57 % 21 without signs of OSA 43 referred to sleep clinic 34 % 10 / 11 has OSA AHI: 18 (5-43) CPAP indicated!!!

49 Health, social and economical consequences of OSA - in Denmark Higher rates of - health related contact - medication use - unemployment Annual excess (direct/indirect cost): DKK pts with type 2 diabetes - 34% has OSA - ~ 2.5 mia DKK per year Jennum and Kjellberg, Thorax 2011

55 DIABOSA study Background OSA is associated with: hyperglycaemia insulin resistance in non-diabetic subjects hypertension dyslipidaemia CPAP treatment improves insulin sensitivity in non-diabetic subjects reduces nighttime blood glucose in T2DM no change in HbA1c or insulin resistance in T2DM

56 NT-proBNP in type 2 diabetes Elevated in type 2 diabetes with BP, UAE, LVDD and dysfunction Independent predictor of all cause mortality cardiovascular mortality Risk marker for CVD and heart failure in type 2 diabetic patients with microalbuminuria
