Abstract
- Obstructive sleep apnoea syndrome (OSAS) is a sleep disorder that leads to metabolic abnormalities and increased cardiovascular risk. This study aimed to define the expression and clinical significance of biomarkers involved in oxidative stress in patients with OSAS. A prospective study was designed to compare outcomes of oxidative stress laboratory tests in three groups of subjects. The study involved the recruitment of three groups of subjects, 10 patients with obstructive sleep apnoea syndrome with AHI30; 10 patients suffering from snoring at night with AHI15; 10 patients with nasal respiratory impairment with AHI5. Patients were subjected to skin prick tests for common aero-allergens, nasal endoscopy, active anterior rhinomanometry, fibrolaryngoscopy and polysomnography; and extra-routine diagnostic tests and procedures; analysis of oxidative and antioxidant (plasma thiol groups) biomarkers in blood and urine samples. No statistical differences in age, sex distribution or body mass index were present between the three groups (p0.05). There were significant differences in AHI among the three groups of patients (p0.05). No statistical significance was found in the Analysis of Variance (ANOVA) test (p0.05) between the levels of biomarkers of oxidative stress in the three populations studied. The results of our study show that the nose can play a role in the pathogenesis of OSAS through the production of biomarkers of oxidative stress.La sindrome delle apnee ostruttive del sonno (OSAS) è una malattia che può portare ad alterazioni metaboliche e a un’aumentata incidenza di patologie cardiovascolari. Questo studio ha lo scopo di definire l’espressione e il significato clinico di biomarkers coinvolti nello stress ossidativo nei pazienti con diagnosi di OSAS. I risultati degli esami di laboratorio dello stress ossidativo sono stati confrontai prospetticamente in tre gruppi di soggetti: 10 con sindrome delle apnee ostruttiva del sonno con Apnea Hypopnea Index (AHI)30; 10 con roncopatia notturna e AHI15 e 10 con insufficienza respiratoria nasale e AHI5. I pazienti sono stati sottoposti a test cutanei per aero-allergeni comuni, rinoscopia anteriore, rinomanometria anteriore attiva, fibrolaringoscopia e polisonnografia. Per la ricerca dei biomarkers dello stress ossidativo sono stati effettuati test diagnostici in campioni di sangue e urine. I gruppi sono risultati omogenei per età, sesso e distribuzione del Body Mass Index (BMI) (p0.05). Ci sono state differenze significative nell’AHI tra i tre gruppi di pazienti (p0.05). Nessuna significatività statistica è stata identificata (p0.05) tra i livelli di biomarkers di stress ossidativo nelle tre popolazioni studiate. I risultati del nostro studio hanno mostrato che il naso può svolgere un ruolo nella patogenesi dell’ OSAS, attraverso la produzione di biomarkers di stress ossidativo.
