Cardiometabolic Profile

Obstructive sleep apnoea (OSA) is positively associated with cardiometabolic diseases; however, high levels of physical activity could decrease the incidence of OSA and associated comorbidities.In this study we aimed to examine the incidence of OSA in relation to physical activity, and its role as a protective factor in individuals with OSA on the incidence of cardiometabolic diseases, in an 8–9-year follow-up study. We analysed data of 658 volunteers from the São Paulo Epidemiologic Sleep Study (EPISONO), a cohort study of individuals aged 20–80 years, collected through polysomnography, the International Physical Activity Questionnaire and an assessment of cardiometabolic profile.Active subjects had a lower risk of developing OSA compared with nonactive subjects (relative risk 0.877, 95% CI 0.296–0.855) and there was a reduced risk of developing type 2 diabetes mellitus in active/apnoeic subjects (relative risk 0.493, 95% CI 0.252–0.961) compared with nonactive subjects. Metabolic equivalent was negatively associated to cardiometabolic markers, such as C-reactive protein (exp(B)=0.720; p=0.001), interleukin-6 (exp(B)=0.991; p=0.03), insulin (exp(B)=0.982; p=0.03), triglycerides (exp(B)=0.997; p<0.001), homeostasis model assessment for insulin resistance (exp(B)≤0.946; p<0.024), quantitative insulin sensitivity check index (exp(B)=992.4; p<0.001) and mean arterial pressure (exp(B)=0.987; p=0.001).Physical activity was a protective factor against type 2 diabetes mellitus in apnoeic individuals; moreover, being active reduced the risk of developing OSA and was associated with a better cardiometabolic profile.

ObjectiveWe estimated the prevalence of nocturnal intermittent hypoxia, a surrogate marker of obstructive sleep apnoea, among type 2 diabetes mellitus (T2DM) patients and examined the association between nocturnal intermittent hypoxia and microvascular diseases.Design and methodsWe recruited 513 Japanese patients (292 men and 221 women) with T2DM. Nocturnal intermittent hypoxia was diagnosed using the 3% oxygen desaturation index, with less than five events per hour corresponding to normal and five events or more per hour corresponding to nocturnal intermittent hypoxia.ResultsThe prevalence of nocturnal intermittent hypoxia was 45.4% among T2DM patients. The nocturnal intermittent hypoxia group was older and had a higher BMI, greater weight change since the age of 20 years, higher smoking rate and increased prevalence of hypertension, hyperlipidaemia, microalbuminuria and macroalbuminuria. Microalbuminuria (model 1: odds ratio (OR), 3.41; 95% CI, 1.85–6.40; model 2: OR, 3.69; 95% CI, 1.85–7.59 and model 3: OR, 3.12; 95% CI, 1.45–6.95) and nephropathy (model 1: OR, 4.51; 95% CI, 1.58–15.1; model 2: OR, 7.31; 95% CI, 2.11–31.6 and model 3: OR, 5.23; 95% CI, 1.45–23.8) were derived as factors from all the three statistical models and constantly associated with nocturnal intermittent hypoxia only in women.ConclusionsNocturnal intermittent hypoxia was highly prevalent among T2DM patients and may be an independent associated risk factor for microalbuminuria in Japanese women with T2DM.

AbstractObstructive sleep apnoea (OSA) is associated with type 2 diabetes mellitus (T2DM). However, mechanisms mediating association between these two conditions remain unclear. This study investigated, whether the OSA-associated changes in adipose tissue lipolysis might contribute to impaired glucose homeostasis in patient with T2DM. Thirty-five matched subjects were recruited into three groups: T2DM + severe OSA (T2DM + OSA, n = 11), T2DM with mild/no OSA (T2DM, n = 10) and healthy controls (n = 14). Subcutaneous abdominal adipose tissue microdialysis assessed spontaneous, epinephrine- and isoprenaline-stimulated lipolysis. Glucose metabolism was assessed by intravenous glucose tolerance test. Spontaneous lipolysis was higher in the T2DM + OSA compared with the T2DM (60.34 ± 23.40 vs. 42.53 ± 10.16 μmol/L, p = 0.013), as well as epinephrine-stimulated lipolysis (236.84 ± 103.90 vs. 167.39 ± 52.17 µmol/L, p < 0.001). Isoprenaline-stimulated lipolysis was unaffected by the presence of OSA (p = 0.750). The α2 anti-lipolytic effect was decreased in T2DM + OSA by 59% and 315% compared with T2DM and controls (p = 0.045 and p = 0.007, respectively). The severity of OSA (AHI) was positively associated with spontaneous (p = 0.037) and epinephrine-stimulated (p = 0.026) lipolysis. The α2-adrenergic anti-lipolytic effect (p = 0.043) decreased with increasing AHI. Spontaneous lipolysis was positively associated with Insulin resistance (r = 0.50, p = 0.002). Epinephrine-stimulated lipolysis was negatively associated with the Disposition index (r =  − 0.34, p = 0.048). AHI was positively associated with Insulin resistance (p = 0.017) and negatively with the Disposition index (p = 0.038). Severe OSA in patients with T2DM increased adipose tissue lipolysis, probably due to inhibition of the α2-adrenergic anti-lipolytic effect. We suggest that dysregulated lipolysis might contribute to OSA-associated impairments in insulin secretion and sensitivity.
