口腔扁平苔藓患者血清IL-2、IL-4、IL-6水平与临床症状的相关性

目的 探讨不同类型口腔扁平苔藓(OLP)患者血清IL-2、IL-4、IL-6在OLP发病及治疗中的意义。方法 采用ELISA方法检测60例各型OLP患者血清IL-2、IL-4、IL-6的水平，记录患者的疼痛程度、充血和糜烂面积。结果 OLP患者血清IL-2、IL-4水平较对照组无显著差异，而各型OLP患者IL-6显著升高。糜烂型OLP患者IL-4水平显著高于对照。血清IL-2、IL-4水平与疼痛程度、充血面积和糜烂面积之间无相关性，而IL-6与三者呈正相关。结论 本研究支持自身免疫机制是OLP的发病机制之一的观点；在OLP的不同阶段患者的免疫状态是变化的；IL-6在OLP的发病中发挥了一定作用。血清IL-6水平也许可以作为动态监测OLP疾病进展的指标和疗效观察的指标。

口腔扁平苔藓患者血清中白细胞介素-12和白细胞介素-27表达与免疫功能的相关性

目的了解口腔扁平苔藓（OLP）患者血清中白细胞介素（IL）-12和IL-27的表达与患者免疫功能状况的相关性,探讨IL-12和IL-27在OLP免疫发病机制中的作用及意义。方法 选取对照组健康者20例和OLP组患者30例（其中网纹型15例,糜烂型15例）,通过流式细胞术分析OLP患者外周血淋巴细胞亚群CD3+、CD4+、CD8+、CD19+、CD16+56[自然杀伤细胞（NK）]的表达情况,散射比浊法检测患者体液免疫指标免疫球蛋白（Ig）G、IgA、IgM、C3、C4的表达情况。采用酶联免疫吸附试验（ELISA）方法检测血清中IL-12和IL-27的表达水平,分析IL-12和IL-27的表达与OLP患者免疫功能状况及临床特征的相关性。结果 与实验室标准值相比,OLP患者细胞免疫中CD3+、CD4+、CD8+水平降低,CD19+水平增高（P<0.05）;体液免疫中IgM水平增高,C4水平降低（P<0.05）。OLP患者血清中IL-12与IL-27表达水平均高于对照组（P<0.05）。同时相关分析显示,OLP患者血清中IL-12和IL-27的表达水平呈正相关关系（r=0.912,P<0.01）。但是IL-12及IL-27表达水平与OLP体征计分、病程计分等临床特征无相关性（P>0.05）。OLP患者中IL-12和IL-27的表达与CD16+56（NK）存在负相关关系（r₁=-0.416,P₁=0.022;r₂=-0.392,P₂=0.032）,与IgG存在正相关关系（r₁=0.445,P₁=0.014;r₂=0.549,P₂=0.002）。结论OLP患者主要以细胞免疫功能低下为主,同时伴有一定程度的体液免疫功能的紊乱。IL-12和IL-27的异常高表达可能协同引起且促进了OLP的炎症发生发展,并且通过机体代偿性负反馈作用参与了对炎症性免疫应答的调节,在OLP的发病机制中起到了一定作用。

Cellular immune correlates of clinical severity in oral lichen planus: preliminary association with mood states

OBJECTIVES: We investigated cellular immune and psycho-immune dysfunctions in patients with erosive and non-erosive oral lichen planus (OLP) lesions.
METHODS: Patients with erosive or non-erosive OLP were screened at the UCLA Dental Clinic. The profile of mood states (POMS) was administered. T lymphocyte subpopulations were monitored by dual fluorescence. T lymphocytes were stimulated with phytohemagglutinin (PHA) for assessment of markers of activation by flow cytometry and of interleukin (IL)-2 production by ELISA.Plasma cortisol and neopterin levels were assessed by radioimmunoassay.
RESULTS: Circulating T cells that express the cluster of differentiation no.4 (CD4⁺) but devoid of the CD45RA marker, and POMS score were significantly associated ( r = 0.83, P < 0.05) in the patients we studied. We found a significantly higher ( P < 0.05) per cent and absolute lymphocyte numbers of circulating CD4+CD45RA cells in the OLP patients with erosive lesions, compared to OLP patients with non-erosive lesions. The ratio of CD4⁺ CD45RA⁺ over CD4+CD45RA cells was significantly ( P < 0.05) biased toward the CD4+CD45RA subpopulation in OLP patients with erosive lesions (ratio = 0.19 ± 0.09) compared to patients with non-erosive OLP lesions (ratio = 0.47 ± 0.15). The expression of CD54, but not that of CD69, was significantly blunted ( P < 0.05) in OLP patients following CD3⁺ cell stimulation. IL-2 production and plasma neopterin were normal in these patients. There was no correlation between plasma cortisol and T cell populationS. CONCLUSIONS: We find fine differences in psycho-immune interactions between patients afflicted with non-erosive OLP lesions compared to those with erosive OLP lesions.     

Peripheral T-cell subsets in patients with reticular and atrophic-erosive oral lichen planus

OBJECTIVE: Oral lichen planus (OLP) presents with various clinical forms that can be classified into 2 major types: reticular OLP and atrophic-erosive OLP. Our objective was to investigate immunologic differences between these 2 types. STUDY DESIGN: We investigated possible immunologic differences between 26 patients with reticular OLP and 26 patients with atrophic-erosive OLP. RESULTS: No differences were detected in serum Ig levels or complement levels. However, the mean proportions of CD4+CD45RO+ and DR+ lymphocytes were significantly higher in patients with atrophic-erosive OLP than in patients with reticular OLP, whereas the mean proportion of CD8+CD45RA+ lymphocytes was significantly lower in patients with atrophic-erosive OLP. CONCLUSION: These findings suggest that the 2 clinical types of OLP might have different immunopathogenic mechanisms.     

Serum cytokine levels in patients with oral mucous membrane disorders

Serum cytokine levels were examined in 18 oral squamous cell carcinoma (SCC), 26 lichen planus (OLP), 20 recurrent aphthous stomatitis (RAS), 8 herpetic gingivostomatitis (HGS), 16 pseudomembrane candidiasis (PMC) and 19 acute bacterial infection (ABI) cases. All SCC and most PMC patients possessed clear serum IL-3. No clear increase of IL-4 was observed in most cases though over 20 pg/ml were found in a few OLP, RAS and ABI. ABI exhibited the highest IL-6, and the cytokine level was lower in RAS, PMC, HGS and OLP in this order. Suppressed IL-6 activity was elevated with improvement of HGS lesion. TNF-alpha increased in 9 OLP, but the levels were below 100 pg/ml in all cases. Most SCC possessed higher GM-CSF activity than the controls. Increase of the cytokine corresponding with improvement of the oral lesion was seen in HGS, but not in OLP. From these results, each serum cytokine seems to reflect a characteristic pathophysiology of individual oral disorder.     

Elevated production of salivary nitric oxide in oral mucosal diseases

Nitric oxide (NO) is known to play an important role in biological systems. In this study, we measured levels of NO in the saliva of 39 patients with oral mucosal diseases: 21 had oral lichen planus (OLP) and 18 had recurrent aphthous ulceration (RAU). NO was assayed using the Griess reagent, which measures nitrite (NO2), the byproduct of NO. NO2 was detected in all tested samples, and levels in the saliva of patients were significantly increased relative to those of healthy subjects. We also examined the effect of NO on fibroblasts, keratinocytes and NA cells (an epithelial cancer cell line) in vitro. S-nitroso-N-acetyl-DL-penicillamine (SNAP) and 3-morpholinosydnonimine (SIN-1) were used as NO donating reagents. The results revealed that cell viability was significantly reduced by NO derived from SNAP and SIN-1 in a dose-dependent manner. Although the role of salivary NO in normal physiology is as yet unknown, these findings suggest that excessive salivary NO plays a potential role in modifying oral mucosal diseases as a physiopathological regulator.     

Serum immunoglobulins and autoantibodies in patients with oral lichen planus

A qualitative and quantitative determination of serum immunoglobulins was made in 34 patients (27 female, 7 male) with histologically verified oral lichen planus (OLP). The subjects ranged in age from 33 to 80 years and 28 of the cases had OLP changes of atrophic-erosive type. The possible presence of rheumatoid factors (RF), antinuclear antibodies (ANA) or antibodies to mitochondrias, renal glomeruli and smooth muscles was studied in 30 of the patients. The investigation also comprised a control group of 23 patients (17 female, 6 male) without mucosal changes. Immunoelectrophoresis showed an abnormal pattern in 10 OLP cases (29%), the most common change being a polyclonal increase of IgG in 8 persons. Elevated levels of serum IgG (greater than 15 g/l) were seen in a total of 9 OLP patients (26%), but only in 1 of the control cases (4%). The mean IgG value was significantly higher in the OLP than in the control group, 13.4 and 10.3 g/l, respectively. Regarding levels of IgA and IgM, no difference was noted between the groups. Autoantibodies were registered in 27% of the OLP patients and in 9% of the controls. The immune changes could be correlated in some respect to positive fungal cultures, allergies and decreased unstimulated saliva, but not to age, endocrine disorders or joint diseases.
