AB  - Purpose: Obstructive sleep apnea (OSA) is characterised by increased systemic inflammation, and is often accompanied with type 2 diabetes mellitus (T2DM) and cardiovascular disease. The aim of this investigation was to evaluate gene expression of resistin, its receptor CAP1 and CD36 as the indicators of the inflammatory changes in PBMCs in relation to the severity of OSA, and the presence of type 2 diabetes mellitus (T2DM) in OSA. Methods: Severity of OSA was defined by the apnea/hypopnea index (AHI): AHI < 30: mild to moderate OSA (MM-OSA), AHI ≥ 30: severe OSA (S-OSA). Presence of T2DM was captured: OSA with T2DM (OSA + T2DM), OSA without T2DM (OSA-T2DM). PBMC resistin, CAP1, and CD36 mRNA were determined by real-time PCR. Results: Resistin mRNA was significantly upregulated in S-OSA (N = 54) compared to the MM-OSA (N = 52, P = 0.043); CAP1 and CD36 mRNA levels did not differ between the groups (P = 0.302; P = 0.166, respectively). Resistin mRNA was significantly upregulated in OSA + T2DM (N = 29) compared to the OSA-T2DM (N = 77, P = 0.029); CAP1 and CD36 mRNA levels did not differ between the groups (P = 0.662; P = 0.108, respectively). AHI and T2DM were independent predictors of resistin mRNA above the 75th percentile (OR = 3.717 [1.152–11.991]; OR = 3.261 [1.000–10.630], P = 0.042 respectively). Conclusion: Resistin gene upregulation in S-OSA indicates its possible contribution to increased inflammation in S-OSA and makes it a possible marker of the disease severity. Resistin gene upregulation in OSA + T2DM suggests that a joint effect of these two comorbidities may have a major contribution to increased inflammation and complications that arise from this state.

AB  - Objectives: Obstructive sleep apnea (OSA) is a common condition closely related to obesity, insulin resistance, dyslipidemia, and cardiovascular disease. The aim of this study was to explore the possible relationship between OSA and proprotein convertase subtilisin/kexin type 9 (PCSK9). Methods: Full-night polysomnography was performed on 150 participants who were divided into three groups: controls, OSA patients on statin therapy, and OSA patients not on statin therapy. Biochemical markers, plasma low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subclasses, and PCSK9 were determined. Results: PCSK9 was highest in OSA patients on statins compared to the control group and to OSA patients not on statins (p = 0.036 and p = 0.039, respectively), after adjustment for body mass index (BMI). LDL diameter was greater in OSA patients not on statins compared to OSA patients on statins (p = 0.032). PCSK9 was highest in the group of patients with all three risk factors (diagnosed OSA, statins, BMI ≥25 kg/m2) compared to groups with no, one, and two risk factors (p = 0.031, p = 0.001, and p = 0.029, respectively). Presence of OSA, statin therapy, and BMI ≥25 kg/m2 when combined were independently associated with higher levels of PCSK9 when adjusted for antihypertensive therapy, small dense LDL, and HDL 3c subclass (odds ratio = 2.849; interquartile range [1.026–7.912], p = 0.044). Conclusion: Statin therapy was closely related to PCSK9. OSA along with obesity and statin use induces elevation of PCSK9.

AB  - Background and aims: Obstructive sleep apnea (OSA) is closely linked to obesity and related adverse metabolic changes, including dyslipidemia. However, it is not clear whether OSA is an independent contributing factor to dyslipidemia, or the observed association is a reflection of a concomitant presence of obesity. Additionally, dyslipidemia is usually evaluated through measurement of parameters of routine lipid status, while more precise evaluation of lipid homeostasis is rarely performed in OSA. In this study, we analyzed markers of cholesterol synthesis and absorption in patients with OSA with respect to the presence of obesity and the disease severity. Methods and results: This study enrolled 116 OSA patients. Concentrations of non-cholesterol sterols (NCS), measured by LC-MS/MS, were used as markers of cholesterol synthesis and absorption. Apnea-hypopnea index (AHI) and oxygen saturation (SaO2) were utilized as markers of OSA severity. Serum lipid status parameters were determined by routine enzymatic methods. Markers of cholesterol synthesis were increased (P = 0.005), whilst markers of cholesterol absorption decreased (P = 0.001) in obese OSA patients. Cholesterol synthesis/absorption ratio was elevated in obese subjects (P < 0.001). Concentration of cholesterol synthesis marker lathosterol was significantly higher in subjects with severe OSA (P = 0.014) and we observed a trend of decreased cholesterol absorption in these patients. AHI was revealed as an independent determinant of lathosterol concentration (P = 0.022). Conclusions: Our results suggest that the presence of obesity and severe forms of OSA is characterized by elevated endogenous cholesterol synthesis. AHI was singled out as an independent determinant of the serum level of cholesterol synthesis marker lathosterol.

AB  - Obstructive  sleep  apnea  (OSA)  as  a  worldwide  prevalent  condition  carries  risk  for cardiovascular  and  metabolic  diseases,  ultimately  increasingoverall  mortality  rates.  Non-alcoholic fatty liver disease  (NAFLD) can be considered as the primary metabolic  disease,  but also as a coexisting OSA comorbidity. Although prevalence of NAFLD covers quarter of world population, it increases with OSA presence. It can be speculated that chronic intermittent hypoxia (CIH)  and  sympathetic  nervous  system  overactivity  are  involved  in  NAFLD  pathogenesis  and progression   from   simple   steatosis throughsteatohepatitis   to   fibrosis.   CIH   provides   the environment  for  liveroxidative  stress,  inflammation  and  increases  the  expression  of  genes involved in cholesterol and fatty acids synthesis. Catecholamines increase β-oxidation in liver and release free fatty acids from adipose tissue in plasma which inhibit insulin effects. Obesity and insulin resistance as key playersin NAFLD development and advancement, deepen vicious circle of oxidative stress, inflammation and dyslipidemia. If not treated, OSA in NAFLD patients has been  associated  with inflammation, hepatocytes’ necrosis,  and  fibrosis.  Continuous  positive airway pressure (CPAP) represents gold standard for OSA therapy, allowing the unimpeded air passage through upper parts of respiratory system. However, it has been demonstrated that CPAP therapyhave beneficial effects on cardiometabolic outcomes and slowliver degeneration
AB  - Opstruktivna apneja u snu (OSA) kao oboljenje prevalentno u svetu nosi rizik za nastanak kardiovaskularnih i metaboličkih bolesti, povećavajući ukupnu smrtnost. Bolest nealkoholne masne jetre (eng. non-alcoholic fatty liver disease -NAFLD) se može smatrati primarnom metaboličkom bolešću, ali kao i komorbiditet OSA. Iako prevalenca NAFLD obuhvata četvrtinu svetske populacije, ona se povećava sa prisustvom OSA. Pretpostavlja se da su hronična intermitentna hipoksija (eng. chronic intermittent hypoxia -CIH) i prekomerna aktivnost simpatičkog nervnog sistema uključeni u patogenezu NAFLD i progresiju od steatoze preko steatohepatitisa do fibroze. U jetri CIH stvara uslove za oksidativni stres, inflamaciju i povećava ekspresiju gena koji učestvuju u sintezi holesterola i masnih kiselina. Kateholamini stimulišu b-oksidaciju masnih kiselina u jetri i oslobađaju slobodne masne kiseline iz masnog tkiva u plazmu, koje inhibiraju dejstva insulina. Gojaznost i insulinska rezistencija kao ključni faktori u razvoju i napredovanju NAFLD produbljuju začarani krug oksidativnog stresa, inflamacije i dislipidemije. Ako se ne leči, OSA kod pacijenata sa NAFLD je povezana sa inflamacijom, nekrozom hepatocita i fibrozom. Kontinuirani pozitivni pritisak vazduha (eng. continuous positive airway pressure -CPAP) predstavlja zlatni standard u terapiji OSA, koji omogućava neometani prolaz vazduha kroz gornje delove respiratornog sistema. Međutim, CPAP terapija je pokazala da ima povoljne efekte na kardiometaboličke ishode i da usporava degeneraciju jetre.

Although prevalence of NAFLD covers quarter of world population, it increases with OSA presence. It can be speculated that chronic intermittent hypoxia (CIH)  and  sympathetic  nervous  system  overactivity  are  involved  in  NAFLD  pathogenesis  and progression   from   simple   steatosis throughsteatohepatitis   to   fibrosis.   CIH   provides   the environment  for  liveroxidative  stress,  inflammation  and  increases  the  expression  of  genes involved in cholesterol and fatty acids synthesis. Catecholamines increase β-oxidation in liver and release free fatty acids from adipose tissue in plasma which inhibit insulin effects. Obesity and insulin resistance as key playersin NAFLD development and advancement, deepen vicious circle of oxidative stress, inflammation and dyslipidemia. If not treated, OSA in NAFLD patients has been  associated  with inflammation, hepatocytes’ necrosis,  and  fibrosis.  Continuous  positive airway pressure (CPAP) represents gold standard for OSA therapy, allowing the unimpeded air passage through upper parts of respiratory system. However, it has been demonstrated that CPAP therapyhave beneficial effects on cardiometabolic outcomes and slowliver degeneration, Opstruktivna apneja u snu (OSA) kao oboljenje prevalentno u svetu nosi rizik za nastanak kardiovaskularnih i metaboličkih bolesti, povećavajući ukupnu smrtnost. Bolest nealkoholne masne jetre (eng. non-alcoholic fatty liver disease -NAFLD) se može smatrati primarnom metaboličkom bolešću, ali kao i komorbiditet OSA. Iako prevalenca NAFLD obuhvata četvrtinu svetske populacije, ona se povećava sa prisustvom OSA. Pretpostavlja se da su hronična intermitentna hipoksija (eng. chronic intermittent hypoxia -CIH) i prekomerna aktivnost simpatičkog nervnog sistema uključeni u patogenezu NAFLD i progresiju od steatoze preko steatohepatitisa do fibroze. U jetri CIH stvara uslove za oksidativni stres, inflamaciju i povećava ekspresiju gena koji učestvuju u sintezi holesterola i masnih kiselina. Kateholamini stimulišu b-oksidaciju masnih kiselina u jetri i oslobađaju slobodne masne kiseline iz masnog tkiva u plazmu, koje inhibiraju dejstva insulina. Gojaznost i insulinska rezistencija kao ključni faktori u razvoju i napredovanju NAFLD produbljuju začarani krug oksidativnog stresa, inflamacije i dislipidemije. Ako se ne leči, OSA kod pacijenata sa NAFLD je povezana sa inflamacijom, nekrozom hepatocita i fibrozom. Kontinuirani pozitivni pritisak vazduha (eng. continuous positive airway pressure -CPAP) predstavlja zlatni standard u terapiji OSA, koji omogućava neometani prolaz vazduha kroz gornje delove respiratornog sistema. Međutim, CPAP terapija je pokazala da ima povoljne efekte na kardiometaboličke ishode i da usporava degeneraciju jetre.",
