Аннотация
BACKGROUND: Obstructive Sleep Apnea Syndrome (OSAS) affects approximately 1-5% of children and is linked to cardiovascular, metabolic, and neurobehavioral complications. Dysregulation of inflammatory process and sympathetic nervous system overstimulation leading to increased catecholamine production may contribute to OSAS pathogenesis. Polymorphonuclear Neutrophils (PMN), key cells in the inflammatory process, express adrenergic receptors, including β2-adrenergic receptor (ADRB2), which modulate their functions through an autocrine/paracrine loop. In this pilot study, we aimed to investigate the relationship between OSAS severity, ADRB2 expression in PMN and patient's inflammatory profile before and after adenotonsillectomy.
PATIENTS/METHODS: In this pilot study we enrolled OSAS pediatric patients in which ADRB2, IL-6 and IL-8 mRNA expression levels were evaluated in circulating PMN by RT-PCR.
RESULTS: 9 OSAS pediatric patients, ranged from 3 to 8 years of age, were enrolled in the study. We found that adenotonsillectomy significantly reduced ADRB2 as well as IL-6, IL-8 mRNA expression levels in PMN.
CONCLUSIONS: These findings offer valuable insights into the underlying immune and inflammatory mechanisms of OSAS and open the way for the development of novel therapeutic approaches.
