OBJECTIVE
As a subtype membrane receptor of tumor necrosis factor alpha, not much is known about the link between the soluble TNF receptor-I and obstructive sleep apnea hypopnea syndrome. We hypothesized that the TNF receptor might play an important role in the inflammation in patients with OSAHS, moreover this study was undertakan to investigate the effects of multimodality therapies on its periphery blood level.
METHODS
Seventy-seven adults with habitual snoring and mean age of 34.9 +/- 11 years old consented to participate in the study. All participants were studied with overnight polysomnography, physical examination and a blood crew at baseline. According to the severity of OSAHS, they were categorized into three groups and one control group. Moderate and severe OSAHS groups returned for a repeat test of polysomnography and a blood crew at 3 months after the ENT surgery or continuous positive airway pressure (CPAP). serum levels were measured by using an immunoluminometric assay kit.
RESULTS
(1) Compared with control non-OSAHS group, serum sTNF-R I levels prior to treatment in OSAHS groups were significantly greater, with a mean serum levels at (742 +/- 258 & 340 +/- 102) pg/ml (P < 0.05), respectively. (2) Plasma solube tumor necrosis factor receptor-I responsed sensitively to the effect of comprehensive therapies when we compared its prior treatment levels with post ones. (3) Analysis was used to assess the associations adjusting for age, gender, BMI and weight ,a positive assosiation were found between apnea-hypopnea index (AHI) and sTNF-R I (r = 0.646, P < 0.01) a negative assosiation were found between lowest nadir oxygen saturation (LSaO2) and (r = 0.522, P < 0.01).
CONCLUSIONS
ln summary, independent of age, gender, BMI and weight ,our datas suggest a relationship can be found between the the severity of OSAHS and periphery blood level of soluble TNF receptor-I. Comprehensive therapies is effective in changing sTNF-R I. sTNF-R I may be recommended as a Inflammation factor of OSAHS.
