牙周非手术治疗对2型糖尿病伴牙周炎患者糖代谢及血清白细胞介素6的影响

目的 观察牙周非手术治疗对2型糖尿病伴慢性牙周炎(chronic periodontitis,CP)患者牙周状况、糖代谢及血清白细胞介素6(IL-6)的影响,探讨其可能的影响机制.方法 选取2型糖尿病伴慢性牙周炎(type 2 diabetes mellitus with chronic periodontitis,DMCP组)和不伴有全身系统性疾病的CP患者(CP组)各55例进行牙周非手术治疗,其中DMCP组中糖化血红蛋白(glycated hemoglobin,HbA1c)＜7.00%的患者为血糖控制较好组(A1组),HbAlc≥7.00%的为血糖控制较差组(A2组).在治疗前及治疗后6周、3个月时分别记录全口探诊深度(probing depth,PD)、附着丧失(attachment loss,AL)、出血指数(beeding index,BI)和菌斑指数(plaque index,PLI),并检测空腹血糖(fasting plasma glucose,FPG)、HbA1c及血清IL-6水平.结果 DMCP组和CP组PD、AL、BI、PLI和血清IL-6水平在治疗后6周及3个月时均显著降低(P＜0.05),其中DMCP组血清IL-6从(3.47±0.33)ng/L(治疗前)显著降至(3.21±0.66)ng/L(治疗后6周),再降至(3.03±0.54)ng/L(治疗后3个月).DMCP组治疗后3个月HbA1c水平[(6.80±1.21)%]与治疗前[(7.35±1.73)%]相比显著降低(P＜0.05),其中A2组HbA1c水平从治疗前的(8.72±1.51)%显著降至治疗后3个月的(7.59±1.28)%(P＜0.05),而A1组HbA1c水平则无明显变化(P＞0.05).结论 牙周非手术治疗能够降低DMCP患者血清IL-6水平,并在一定程度上改善患者糖代谢状况;该治疗能显著改善血糖控制较差者的糖代谢,而对血糖控制较好者的糖代谢则无明显影响.

Abstract：

Objective To evaluate the effect of non-surgical periodontal therapy on periodontal status, glycemic control and the level of serum interleukin(IL)-6 in type 2 diabetic patients with chronic periodontitis (DMCP). Methods Fifty-five DMCP and 55 systemically healthy patients with chronic periodontitis(CP) were recruited in this study. The diabetes were classified into two groups, the wellcontrolled group [glycated hemoglobin (HbA1c) ＜ 7.00%]and the poorly controlled group (HbA1c ≥7.00%). All subjects received non-surgical periodontal therapy. Periodontal clinical parameters including periodontal probing depth (PD), attachment loss (AL), bleeding index (BI) and plaque index (PLI) were recorded at baseline, 6 weeks and 3 months after the treatment. Fasting plasma glucose(FPG), HbA1c and the concentration of serum IL-6 were measured. Results At 6 weeks and 3 months after treatment, PD,AL, BI, PLI and the concentration of serum IL-6 of both groups significantly reduced(P ＜ 0. 05). The level of IL-6 in diabetic patients reduced significantly from (3.47 ±0.33) ng/L to (3.21 ±0.66) ng/L and to (3.03 ± 0. 54) ng/L. The HbA1c of diabetic patients reduced significantly 3 months after treatment [(6.80±1.21%]compared with the baseline[(7.35 ± 1.73)%, P ＜0.05]. HbA1c of the poorly controlled group reduced significantly(P ＜0. 05), while HbA1c of the well-controlled diabetes did not show any apparent reduction (P ＞ 0. 05). Conclusions Non-surgical periodontal therapy can effectively reduce the concentration of serum IL-6, thereby improving glycemic control in type 2 diabetes patients with chronic periodontitis. However, there was no any significant reduction of HbA1c in the well-controlled diabetes.
