高聚金葡素联合化学药物治疗口腔癌的疗效与免疫功能观察

目的　评价高聚金葡素 (HAS)联合化疗治疗口腔癌的疗效 ,以及免疫治疗在肿瘤化疗中的应用价值 ,着重从机体免疫状况以及细胞因子的调控方面 ,探讨其作用机理。方法　对 2 6例口腔癌进行颞浅动脉逆行插管术 ,分别进行化疗和 HAS联合化疗两种方式。观察疗效和药物毒副作用 ,并采用流式细胞技术、EL ISA法等测定其免疫状态。结果　治疗组总有效率为 80 % (8/ 10 ) ,无明显毒副作用 ,并减轻化疗所致的毒副作用。口腔癌患者细胞免疫受到不同程度地抑制 ,而体液免疫功能处于正常范围内 ,CIC值的升高与肿瘤免疫抑制相关。观察两组治疗前后免疫学指标 ,发现 HAS可刺激 T- CD+4 细胞增殖 ,并能分泌大量细胞因子如 IL - 2 ,进一步促进细胞免疫应答。化疗对免疫功能有明显的抑制作用 ,而经 HAS治疗后 CD4、CD4/ CD8比值、IL - 2升高较化疗组明显 (P<0 .0 5 )。所以使用 HAS可避免因化疗和手术等所致的术后早期免疫功能下降。但 HAS治疗组术后第二个月免疫功能受到抑制 ,与超抗原所致的免疫耐受有关。结论　高聚金葡素联合化疗疗效显著 ,可减少化疗所致的毒副作用。HAS主要通过刺激 T细胞增殖 ,调节细胞因子的分泌 ,达到增强免疫功能和抗癌目的 ,是一种治疗口腔癌的新型免疫化疗方法     

Assessment of Interleukin‐6 Receptor Inhibition Therapy on Periodontal Condition in Patients With Rheumatoid Arthritis and Chronic Periodontitis

Background: Overproduction of interleukin (IL)‐6 may play a pathologic role in rheumatoid arthritis (RA) and chronic periodontitis (CP). The present study assesses IL‐6 receptor (IL‐6R) inhibition therapy on the periodontal condition of patients with RA and CP. Methods: The study participants were 28 patients with RA and CP during treatment with IL‐6R inhibitor, and 27 patients with RA and CP during treatment without IL‐6R inhibitor. Periodontal and rheumatologic parameters and serum levels of cytokine and inflammatory markers and immunoglobulin G against periodontopathic bacteria were examined after medication with IL‐6R inhibitor for 20.3 months on average (T1) and again 8 weeks later (T2). Results: No differences were observed between the groups in any parameter values at T1, except for serum IL‐6 levels. The anti–IL‐6R group showed a significantly greater decrease in gingival index, bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and serum levels of IL‐6 and matrix metalloproteinase (MMP)‐3 from T1 to T2 than the control group (P <0.05). A significant correlation was found between changes in serum anticyclic citrullinated peptide levels and those in PD and CAL in the anti–IL‐6R group (P <0.05), whereas both groups exhibited a significant association between changes in serum MMP‐3 levels and those in BOP (P <0.05). Conclusion: Changes in periodontal and serum parameter values were different between the patients with RA and CP during treatment with and without IL‐6R inhibitor.

Chemerin as a Novel Crevicular Fluid Marker of Patients With Periodontitis and Type 2 Diabetes Mellitus

Background: The objectives of the present study are to: 1) determine whether gingival crevicular fluid (GCF) chemerin is a novel predictive marker for patients with chronic periodontitis (CP) with and without type 2 diabetes mellitus (t2DM); 2) analyze the relationship between chemerin and interleukin (IL)‐6 in periodontally healthy individuals and in patients with CP and with and without t2DM; and 3) evaluate the effect of non‐surgical periodontal therapy on GCF chemerin levels. Methods: Eighty individuals were split into four groups: 20 who were systemically and periodontally healthy (CTRL), 20 with t2DM and periodontally healthy (DM‐CTRL), 20 systemically healthy with CP (CP), and 20 with CP and t2DM (DM‐CP). Individuals with periodontitis were treated with non‐surgical periodontal therapy. GCF sampling procedures and clinical periodontal measures were performed before and 6 weeks after treatment. Enzyme‐linked immunosorbent assay was used to measure chemerin and IL‐6 levels. Results: Greater values for GCF chemerin and IL‐6 levels were found in CP groups than in periodontally healthy groups, in DM‐CP than in CP, and in DM‐CTRL than in CTRL (P <0.008). GCF chemerin and IL‐6 levels decreased following therapy in CP groups (P <0.02). A comprehensive overview of all groups showed a statistically significant positive correlation of chemerin with IL‐6, glycated hemoglobin, sampled‐site clinical attachment level, and gingival index (P <0.05). Conclusions: In this study, periodontitis and t2DM induced aberrant secretion of chemerin, and non‐surgical periodontal therapy influenced the decrease of GCF chemerin levels in patients with CP with and without t2DM. Furthermore, it suggests GCF chemerin levels may be considered a potential proinflammatory marker for diabetes, periodontal disease, and treatment outcomes.     

Changes in Inflammatory and Metabolic Parameters After Periodontal Treatment in Patients With and Without Obesity

Background: Non‐surgical periodontal treatment decreases serum levels of inflammatory cytokines in patients with and without obesity. However, the changes in metabolic parameters in association with these decreases in levels of inflammatory markers by periodontal treatment have not been evaluated in patients with obesity. The aim of this study is to evaluate the short‐term changes in systemic inflammatory, lipid, and glucose parameters in the presence of obesity after periodontal treatment. Methods: The study included 22 dyslipemic patients with obesity and 24 healthy individuals without obesity with generalized chronic periodontitis. The periodontal parameters, anthropometric measurements, and serum levels of triglyceride, total cholesterol, high‐density lipoprotein cholesterol, low‐density lipoprotein cholesterol, and lipoprotein‐a, high‐sensitive C‐reactive protein, fasting blood glucose, insulin, interleukin‐6 (IL‐6), tumor necrosis factor‐α (TNF‐α), and leptin were measured. A homeostasis model assessment of the insulin resistance (HOMA‐IR) score was calculated before and 3 months after non‐surgical periodontal treatment. Results: Both groups responded well to the periodontal treatment in terms of periodontal parameters. The treatment was also associated with a decrease in serum TNF‐α and IL‐6 levels and HOMA‐IR scores in individuals with obesity and with a decrease in IL‐6 levels in patients without obesity. Conversely, there were insignificant decreases in lipid profiles and serum fasting glucose of patients with obesity. Conclusion: The non‐surgical periodontal treatment causes a decrease in the levels of some circulating proinflammatory cytokines and may be associated with a decrease in insulin resistance in the obese population.     

The influence of surgical treatment of periodontal disease on selected lymphocyte subpopulations important for cellular and humoral immune responses

BACKGROUND: Periodontal disease is a complex pathological process involving a wide spectrum of immunological reactions. The aim of the study was to evaluate the influence of surgical periodontal treatments on peripheral blood lymphocyte subpopulations. METHODS: The study was performed in 40 generally healthy individuals diagnosed with generalized chronic periodontitis and a control group of 36 persons without periodontitis. Peripheral blood lymphocyte subpopulations were examined in both groups. Periodontal treatment was performed, using four different surgical procedures, in the study group. Peripheral blood lymphocyte subpopulations were re-evaluated again after 6 months. RESULTS: Periodontal treatment resulted in a significant improvement of all measured clinical parameters, regardless of the surgical procedure. When evaluated in the study group as a whole, percentages of all but CD8+ T lymphocyte subpopulations were significantly different from the control group at baseline. Values in both groups after treatment were similar. Correlation analysis suggests a connection between the presence of CD25+ cells and selected clinical parameters of periodontal disease (probing depth and clinical attachment loss). CONCLUSIONS: Statistically significant differences in the percentages of selected lymphocyte subpopulations in the peripheral blood of patients and healthy controls were found. The results suggest a correlation between selected clinical periodontal parameters and percentage of activated cells expressing the interleukin (IL)-2 receptor. Periodontal treatment resulted in significant improvement in the measured clinical and immunological parameters. It seems that the type of surgical treatment has little effect on the normalization of quantitative disturbances of the examined peripheral blood lymphocytes.
