维族绝经妇女龈沟液IL-6、血清雌二醇水平与牙周炎的关系

The association between gingival cervicular fluid Interleukin-6 level, serum estradiol status and periodontitis in Uyghur postmenopausal women

目的:探讨维吾尔族绝经早期的牙周炎患者龈沟液IL-6及血清雌二醇(E2)水平与牙周炎的关系。方法:共79例绝经年限均≤5a的妇女纳入本研究。采集30颗牙周健康牙和49颗牙周炎患牙的龈沟液(GCF),记录牙周临床观察指标。采集慢性牙周炎患者的血样本。应用放射免疫分析法检测GCF中IL-6和血清中E2的浓度。结果:牙周健康组GCF中IL-6浓度为(1088.10±102.33)pg/ml;慢性牙周炎组GCF中IL-6浓度明显高于牙周健康牙组(P<0.005);慢性牙周炎患牙GCF中IL-6浓度与GI、PPD、CAL均呈正相关(r=0.564,P<0.005;r=0.335,P<0.05;r=0.324,P<0.05)。血清E2≤30pg/ml组的妇女牙周炎患牙牙周临床指标、GCFIL-6浓度与E2>30pg/ml组无显著差异(P>0.05)。结论:健康牙GCF中含有微量IL-6。牙周炎患牙GCF中IL-6的水平反映了牙周炎症的严重程度,可以尝试作为判断维族妇女牙周病变程度的一个指标。绝经早期患慢性牙周炎的维族妇女,血清E2水平与牙周炎患牙的病变程度及GCF中IL-6的水平无关。

PURPOSE: The purpose of this investigation was to analyze by cross-sectional design the association between GCF IL-6 level, serum E2 level and common clinical measurements of periodontitis in Uyghur postmenopausal women. METHODS: 79 subjects within 5 years after menopause were enrolled in the study. 30 GCF samples were harvested from healthy sites, 49 GCF samples from chronic periodontitis sites. Clinical measurements of each tooth were recorded after obtaining GCF samples. GCF IL-6 and serum E2 levels were measured by radioimmunoassay (RIA). RESULTS: The mean concentration of GCF IL-6 from healthy sites was (1088.10±102.33)pg/ml.The mean concentration of IL-6 from chronic periodontitis sites was significantly higher than that of healthy sites (P<0.005). Positive correlation was found between GCF IL-6 level and clinical measurements (GI, PPD and CAL) (r=0.564, P<0.005; r=0.335, P<0.05; r=0.324, P<0.05). Clinical measurements and GCF IL-6 levels of chronic periodontitis subjects were not different between E2-deficient and E2-sufficient subjects. CONCLUSIONS: These findings suggest that there is lower IL-6 level in GCF from healthy sites; the increasing production of IL-6 may be associated with the initiation and progress of periodontitis. IL-6 may be a valuable indicator of the severity of periodontitis; E2 level is not associated with clinical measurements and GCF IL-6 level of chronic periodontitis of Uyghuy woman in early menopause.
