目的分析冠心病伴牙周炎患者牙周干预治疗前、后血清中炎性因子和脂联素水平的变化,探讨慢性牙周炎与冠心病的关系及牙周干预治疗对冠心病伴牙周炎患者的重要性。方法本研究包括冠心病伴牙周炎患者56例和单纯冠心病不伴牙周炎患者42例。冠心病伴牙周炎患者给予牙周干预治疗,对冠心病组及冠心病伴牙周炎组干预前、后的牙周临床指标及血清炎性因子（CRP、TNF-α、IL-6）和脂联素水平进行比较分析。结果冠心病伴牙周炎组牙周干预后牙周临床指数比干预前明显好转。冠心病伴牙周炎组干预前与冠心病组相比,所有血清炎性因子（CRP、TNF-α、IL-6）水平升高;干预3个月后明显降低（P〈0.05）。冠心病伴牙周炎组干预前水平有所降低的脂联素在干预3个月后明显升高（P〈0.05）。结论慢性牙周炎可增加冠心病的发病风险,牙周干预治疗可降低血清中炎性因子水平,提高血管保护因子水平,对冠心病病程的发展有改善作用。     

C反应蛋白基因多态性与慢性牙周炎的相关性研究

目的 研究中国汉族人群中C反应蛋白(C-reactive protein,CRP)+1444C/T、CRP+1059G/C两种基因多态性与慢性牙周炎的关系,为进一步探讨CRP在牙周炎与冠状动脉粥样硬化性心脏病相关性中的作用和意义提供依据.方法 检测126例慢性牙周炎患者(CP组)和113名牙周健康或龈炎者(对照组)的牙周临床指数(附着丧失、探诊深度和探诊出血)、CRP水平及CRP+1059G/C、CRP+1444C/T基因多态性分布情况.结果 CP组中CRP+1059C等位基因的频率为6.7%(17/252);对照组4.9%(11/226),CP组与对照组之间的基因型分布和等位基因频率的分布差异均无统计学意义(0.250.5).结论 CRP+1059G/C、+1444C/T基因可能是CRP的功能性基因,尽管牙周炎与心血管疾病显著相关且CRP+1059G/C、+1444C/T与心血管疾病有相关性,但是这两个基因位点可能对中国汉族人群牙周炎患者的血清CRP水平影响不显著.

Release of cytokines by stimulated peripheral blood mononuclear cells in chronic periodontitis

Objective

The emergence of periodontal medicine increased interest in defining the behaviour of peripheral blood cells in periodontitis subjects in comparison with healthy group. The aim of this study was to evaluate the levels of interleukin (IL)-8, tumour necrosis factor-α (TNF-α), IL-6 and IL-10 released by Escherichia coli lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMC) obtained from the peripheral blood of chronic periodontitis subjects.

Design

PBMC samples were isolated from 19 systemically healthy donors, divided into generalized chronic periodontitis (n = 10) and healthy (n = 9) subjects. Cells were incubated for 24–48 h in 500 μL wells containing RPMI 1640 and stimulated with 1.0 ng/mL of E. coli LPS. Supernatants were used to quantify the amounts of IL-8, TNF-α, IL-6 and IL-10 released using enzyme-linked immunosorbent assay (ELISA).

Results

PBMC cells from periodontitis subjects released higher levels of TNF-α and IL-6 than those from healthy subjects (P < 0.05). Conversely, the supernatants of the stimulated PBMC cells obtained from healthy subjects presented higher amounts of IL-8 than those from periodontitis (P < 0.05). No differences were observed in the levels of IL-10 (P > 0.05) between groups.

Conclusion

In conclusion, the results of the present study showed that E. coli LPS-stimulated PBMC from subjects with periodontitis present a different pattern of cytokine release when compared to PBMC from healthy subjects. This phenomenon could have implications locally, in periodontitis, as well as in systemic diseases.

Quantification of tryptase-TIM-3 double-positive mast cells in human chronic periodontitis

ObjectivesMast cells (MCs) are implicated in the pathogenesis of allergic reactions and inflammatory conditions through the release of inflammatory mediators. So far limited attention has been given to the role of MCs in periodontitis. T cell immunoglobulin mucin domain (TIM)-3 is an immunomodulatory molecule and influences MC function. However, whether TIM-3 is expressed on MCs in the process of human periodontal disease has not been reported. Therefore, we identified MCs by toluidine blue staining and examined the expression of TIM-3 on tryptase-positive MCs in different severities of human chronic periodontitis using double-immunofluorescence staining in this study.Material and methodsA total of 83 human periodontal specimens were involved in this study, including healthy control tissues (n = 25), chronic moderate periodontitis (n = 28), and chronic severe periodontitis (n = 30). The gingival specimens were fixed in 10% buffered formalin, stained with haematoxylin and eosin for histopathology, with toluidine blue for MCs, and with double-immunofluorescence for identification of tryptase-TIM-3 double-positive MCs in gingival tissues.ResultsCompared with healthy controls, the score of gingival tissue inflammation was significantly increased in the chronic moderate periodontitis (P = 0.013) and chronic severe periodontitis (P < 0.0001), and the densities (cells/mm²) of tryptase-TIM-3 double-positive MCs were significantly increased in both the chronic moderate (P = 0.011) and severe periodontitis groups (P < 0.0001). However, compared with the chronic moderate periodontitis group, both the score of gingival tissue inflammation (P = 0.012) and the density of tryptase-TIM-3 double-positive MCs (P = 0.011) in gingival tissue were significantly increased in the severe periodontitis groups.ConclusionSignificantly increased number of tryptase-TIM-3 double-positive MCs had the similar tendency as the severity of periodontitis inflammation in human chronic periodontitis. Our data suggest that TIM-3 may have a role on MCs in human chronic periodontitis.     

中、重度牙周炎与冠心病患者C反应蛋白及血脂水平的比较

目的 研究汉族人群中、重度牙周炎与冠心病的相关性并初步探讨C反应蛋白在二者相关性中的可能作用.方法 检测和分析40名健康者(健康组)、40例中、重度牙周炎患者(牙周炎组)、28例冠状动脉粥样硬化性心脏病(简称冠心病)患者(冠心病组)及47例同时患冠心病及中、重度牙周炎的患者(冠心病+牙周炎组)血清C反应蛋白水平、血脂水平(血清低密度脂蛋白、高密度脂蛋白胆固醇、总胆固醇和甘油三酯)和牙周临床指数(附着丧失、探诊深度和探诊出血).结果 单因素方差分析结果显示,健康组、牙周炎组、冠心病组及牙周炎+冠心病组的血清C反应蛋白水平分别为(1.30±0.15)、(2.44±0.18)、(5.99±0.82)和(6.88±0.71)mg/L,各组血清C反应蛋白水平间的差异具有统计学意义(P<0.001),且经协方差分析校正年龄、受教育状况、血压和体重指数后显示,各组血清C反应蛋白水平间的差异仍具有统计学意义(P<0.001).多元Logistic回归分析结果显示,中、重度牙周炎患者发生冠心病的可能性高于牙周健康者,其发生冠心病的相对风险率比值比为2.417(P=0.039;95%CI:1.126～6.659).经协方差分析校正年龄、受教育状况、血压和体重指数后,各组血清总胆固醇水平间差异仍具有统计学意义(P=0.017).结论 严重的牙周感染可能通过改变血清C反应蛋自水平继而影响全身炎症反应和冠心病的发生及发展,可能是冠心病事件的危险因素之一.     

Oxidative damage of rat liver induced by ligature-induced periodontitis and chronic ethanol consumption

Objective

Oxidative stress plays a central role in the initiation and progression of liver disease. Chronic ethanol consumption induces oxidative damage of the liver. Using a rat model, we previously showed that chronic administration of lipopolysaccharide and proteases to gingival sulcus induced both periodontal inflammation and liver injury. Periodontitis and ethanol consumption may have an additional effect on hepatic oxidative damage. The present study investigated the effects of periodontitis on ethanol-induced oxidative damage of the liver using a rat model.

Design

Male Wistar rats were divided into four groups (six rats/group). During the experimental period of eight weeks, two groups were fed an ethanol-containing liquid diet, and two groups were on a pair-fed control diet. Four weeks prior to the end of the experimental period, one group from each dietary treatment was ligated to induce periodontitis, while the other group was left unligated. In order to evaluate hepatic oxidative damage, the level of hexanoyl-lysine and the ratio of reduced form glutathione/oxidized form glutathione (GSH/GSSG) was determined. The concentration of blood hexanoyl-lysine was also measured as an index of circulating lipid peroxide.

Results

Ligature-induced periodontitis increased plasma levels of hexanoyl-lysine. In the liver, periodontitis decreased the GSH/GSSG ratio, and the combination of periodontitis and ethanol consumption induced a significant increase in hexanoyl-lysine level compared to ethanol consumption alone.

Conclusion

In the rat model, ligature-induced periodontitis increased plasma lipid peroxide, decreased the hepatic GSH/GSSG ratio and augmented ethanol-induced lipid peroxidation in the liver.     

Association between periodontitis and chronic obstructive pulmonary disease in a chinese population

Background: A relationship between periodontitis and chronic respiratory disease has been suggested by recent studies. The aim of this study is to explore the association between periodontitis and chronic obstructive pulmonary disease (COPD) in a Chinese population. Methods: We conducted a case-control study of 581 COPD cases and 438 non-COPD controls. Lung function examination, a 6-minute walk test, and the British Medical Research Council questionnaire were performed. Periodontal clinical examination index included probing depth (PD), attachment loss (AL), bleeding index (BI), plaque index (PI), and alveolar bone loss. A validated index for predicting COPD prognosis, the body mass index, airflow obstruction, dyspnea, and exercise capacity (BODE) index, was also calculated. Results: Participants with more severe COPD were more likely to have severe periodontal disease. PD, AL, PI, alveolar bone loss, and the number of teeth were significantly associated with all stages of COPD (all P <0.001). When compared to controls (BODE = 0), participants with higher BODE scores had significantly higher AL (P <0.001), BI (P = 0.027), PI (P <0.001), alveolar bone loss (P <0.001), and the number of teeth (P <0.001). PI appeared to be the main periodontal health-related factor for COPD, with an odds ratio (OR) = 9.01 (95% CI = 3.98 to 20.4) in the entire study population OR = 8.28 (95% CI = 2.36 to 29.0), OR = 5.89 (95% CI = 2.64 to 13.1), and OR = 2.46 (95% CI = 1.47 to 4.10) for current, smokers, and non-smokers, respectively. Conclusion: Our study found a strong association between periodontitis and COPD, and PI seemed to be a major periodontal factor for predicting COPD among Chinese adults.     

Identification of periodontal pathogens and severity of periodontitis in patients with and without chronic kidney disease

Objective

In this study of patients with chronic periodontitis (CP), the severity of the disease and the main periodontal pathogens identified in patients with chronic kidney disease (CKD) were compared with those detected in individuals without systemic disease.

Design

Nineteen patients with CP without evidence of systemic disease (control group), 25 patients with CP and CKD who were in the pre-dialysis stages (pre-dialysis group), and 22 patients with CP and CKD who were on renal replacement therapy (RRT group) were examined. The severity of CP was based on the investigation of probing depth (PD) and clinical attachment level (CAL). The definition and stage of CKD were based on the criteria proposed by the Kidney Disease Outcomes Quality Initiative of the National Kidney Foundation. Glomerular filtration rate (GFR) was estimated using the equation of Modification of Diet in Renal Disease and the identification of microorganisms in subgingival plaque was performed using polymerase chain reaction (PCR).

Results

Candida albicans, Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola were more common in patients who were on RRT and pre-dialysis than in control subjects. CP was more severe in patients with CKD. A strong association was observed between the frequency of C. albicans (P = 0.056), P.gingivalis (P = 0.008), T. denticola (P = 0.013) and CAL, when CKD patients were compared with the control group.

Conclusion

CP is more severe and is associated with increased frequency of C. albicans, P. gingivalis, T. forsythia, and T. denticola in patients with CKD.

Periodontal therapy reduces arginase activity in saliva of patients with chronic periodontitis

This present study evaluated the salivary arginase activity (SAA) in patients with chronic periodontitis and the effect of periodontal therapy on the activity of such enzyme. Thirty-six patients (mean age, 45.97 ± 14.52), 18 chronic periodontitis subjects (test group), and 18 periodontally healthy individuals (control group) participated in the study. Clinical periodontal examinations included measurements of probing pocket depth (PD), clinical attachment level (CAL), plaque (PI), and gingival (GI) indexes. The test group received periodontal therapy according to individual needs. The saliva sample was collected from all study population at baseline (both groups) and 30 days after periodontal therapy (test group). SAA was determined by measuring the l-ornithine formation from l-arginine and was expressed as mU/ml. The results showed that the mean values of SAA were statistically different between control and test groups. SAA was about 2.5 times higher in test than control groups. Thirty days after periodontal therapy, enzyme levels were 1.56 times lower than before periodontal therapy. We concluded that SAA is increased in chronic periodontitis subjects when compared to periodontally healthy individuals and that periodontal therapy significantly reduced SAA levels. It was suggested that in the near future, SAA may be used as a salivary marker of periodontal status.

Serum leveis of inflammatory markers in type 2 diabetes patients with chronic periodontitis

Diabetes has been associated with periodontitis, but the mechanisms through which periodontal diseases affect the metabolic control remain unclear.

Objective

This study aimed to evaluate serum leveis of inflammatory markers, IL-8, IL-6 and monocyte chemoattractant protein 1 (MCP-1), in type 2 diabetic patients in the presence of chronic periodontitis.

Material and Methods

Forty two individuals were enrolled in this study and assigned to one of five groups: diabetes mellitus with inadequate glycemic control and periodontitis (DMI+P, n = 10), diabetes mellitus with adequate glycemic control and periodontitis (DMA+P, n = 10), diabetes mellitus without periodontitis (DM, n = 10), periodontitis without diabetes (P, n=6), and neither diabetes nor periodontitis (H, n = 6). Periodontal clinical examination included visible plaque index (PL), gingival bleeding index (GB), probing depth (PD), attachment level (AL) and bleeding on probing (BP). Glycemic control was evaluated by serum concentration of glycated hemoglobin (HbAlc). Inflammatory serum markers IL-8, IL-6 and (MCP-1) were measured by ELISA.

Results

DMI+P and DMA+P groups presented higher PD (p=0.025) and AL (p=0.003) values when compared to the P group. There were no significant differences among groups for IL-6, IL-8 and MCP-1 serum levels.

Conclusions

Although periodontitis was more severe in diabetic patients, the serum levels of the investigated inflammatory markers did not differ among the groups.
