Changes of circulating inflammatory factors after operation in children with obstructive sleep apnea hypopnea syndrome

Abstract

Objective To observe the changes of circulating tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) levels in children with obstructive sleep apnea-hypopnea syndrome (OSAHS) before and after operation,and to assess the effect of surgical treatment on the levels of these inflammatory factors. Methods Forty-five children with OSAHS underwent adenoidectomy and tonsillectomy were selected as OSAHS group and matched for age and sex to 45 health children control group. Serum levels of TNF-α and IL-6 were detected by high sensitivity ELISA. The hs-CRP was measured by latex-enhanced turbidometry. The serum levels of these factors in OSAHS group before operation were compared with those of the control group and OSAHS group 6 months after operation. Results Serum levels of TNF-α, IL-6, and hs-CRP in OSAHS group were higher than those in the control group (P<0.01), and the levels in OSAHS group 6 months after operation were significantly lower than those before operation (P<0.01). All the serum parameters were correlated positively with AHI, and negatively with LSaO2. Conclusions Operative treatment can effectively correct circulating serum levels of TNF-α,IL-6 and hs-CRP in children with OSAHS. The changes of TNF-α,IL-6 and hs-CRP levels can be a valuable measure in treatment follow-up.
