Obstructive sleep apnoea (OSA) is associated with increased insulin resistance. Triglyceride-glucose index (TyG) is a simple marker of insulin resistance; however, it has been investigated only by two studies in OSA. The aim of this study was to evaluate TyG in non-diabetic, non-obese patients with OSA. A total of 132 patients with OSA and 49 non-OSA control subjects were included. Following a diagnostic sleep test, fasting blood was taken for the analysis of the lipid profile and glucose concentrations. TyG was calculated as ln(triglyceride [mg/dL] × glucose [mg/dL]/2). Comparison analyses between OSA and control groups were adjusted for age, gender, body mass index (BMI) and smoking. TyG was higher in men (p < 0.01) and in ever-smokers (p = 0.02) and it was related to BMI (ρ = 0.33), cigarette pack-years (ρ = 0.17), apnoea–hypopnoea index (ρ = 0.38), oxygen desaturation index (ρ = 0.40), percentage of total sleep time spent with oxygen saturation below 90% (ρ = 0.34), and minimal oxygen saturation (ρ = −0.29; all p < 0.05). TyG values were significantly higher in OSA (p = 0.02) following adjustment for covariates. OSA is independently associated with higher TyG values which are related to disease severity in non-obese, non-diabetic subjects. However, the value of TyG in clinical practice should be evaluated in follow-up studies in patients with OSA.

Background: The interaction of obstructive sleep apnoea (OSA) with vascular risk factors is known as syndrome Z which is also known as the metabolic syndrome or the insulin resistance syndrome and these include the hypertension, central obesity, insulin resistance and hyperlipidaemia. The objective of the present study was to investigate the prevalence and severity of syndrome Z at tertiary care center.Methods: This prospective study was conducted among 40 eligible patients between May and July 2018 at the tertiary care center included adult patients >18years of age. Overnight fasting glucose and lipid levels were measured, and baseline anthropometric data recorded. All sleep studies were scored and reported by a sleep physician. OSA was deemed to be present if the respiratory disturbance index (RDI) was >5, with mild, moderate and severe categories classified according to the Chicago criteria.Results: Mean age of participants was 52.7years, 77.5% were male, Mean BMI and waist circumference were 29.2kg/m2 and 113.8cm respectively. Almost 92.5% participants were known case of HTN, 85.0% were DM and 67.5% Dyslipidemia. Around 60.0% participants were belonged to severe grade of OSAS and 7 (17.5%) patients who fulfilled all five criteria for the diagnosis of the metabolic syndrome had severe OSAS. The prevalence of OSA in the entire group was 95.0%.Conclusions: The prevalence of syndrome Z in present study participants was very high. With the help of history and polysomnogram, metabolic syndrome should be screened for OSA. Early diagnosis and treatment of OSA is the essential part in the treatment of metabolic syndrome and hence CAD.

Resting Energy

Obstructive sleep apnoea (OSA) has been associated with disturbances in energy metabolism and insulin resistance, nevertheless, the links between OSA severity, resting energy expenditure (REE) and insulin resistance (homeostasis model assessment, HOMA-IR) remained unexplored. Therefore, we investigated the effects of OSA severity on REE, and relationships between REE and HOMA-IR in patients with OSA. Forty men [mean (SD) age 49.4 (11.4) years] underwent overnight polysomnography; REE was assessed using indirect calorimetry. REE adjusted for fat-free mass (FFM) was higher in patients with moderate-to severe OSA [n=24; body mass index (BMI) 31.1 (2.7) kg.m-2; apnoea-hypopnoea index (AHI)≥15 episodes.h 1] compared to participants with no clinically significant OSA (n=16; BMI 30.3 (2.2) kg.m-2; AHI<15 episodes.h-1) [median (interquartile range) 30.4 (26.1-31.3) versus 25.8 (24.6-27.3) kcal.kg-1.24 h-1, p=0.005)]. AHI and oxygen desaturation index (ODI) were directly related to REE/FFM (p=0.001; p<0.001, respectively) and to HOMA-IR (p<0.001 for both). In stepwise multiple linear models, REE/FFM was independently predicted by ODI (p<0.001) and age (p=0.028) (R2=0.346); HOMA-IR was independently predicted by ODI only (p<0.001, R2=0.457). In conclusion, male patients with moderate-to severe OSA have increased REE paralleled by impaired insulin sensitivity. Severity of nocturnal intermittent hypoxia reflected by ODI is an independent predictor of REE/FFM and HOMA-IR.
