摘要
目的探讨不同病理类型、不同病程狼疮肾炎(LN)患者的Th1和Th2失衡情况。方法采用酶联免疫吸附试验(ELISA)法测定16名正常人及18例LN患者外周血浆白细胞介素(IL)-18及IL-13水平,同时应用免疫组织化学检测6名正常人肾组织和18例LN患者肾组织IL-18及IL-13的表达量。结果无论在肾组织或外周血,LN患者IL-18水平及IL-13水平均较正常对照组显著上升(P均<0.001),Ⅳ型LN患者血浆IL-18/IL-13较正常对照组显著增高(P<0.05),V型LN患者较正常对照组有降低趋势,但未达统计学意义(P>0.05),而Ⅱ型LN患者其比率数值与正常对照组极其接近;在肾组织局部,不同病理类型LN患者之间IL-18/IL-13比率差异无显著性(P>0.05);血浆IL-18/IL-13比率与肾组织狼疮活动指数(AI)呈正相关(P<0.05),肾组织IL-18/IL-13比率与AI无相关关系(P>0.05)。结论LN患者免疫紊乱状态似乎不能简单的按Th1优势/Th2优势进行二分法分类,其免疫紊乱状态远较此复杂,不同活动状态,不同部位及不同病理类型的狼疮的免疫紊乱状态是不同的。
Objective To investigate the state of Th1/Th2 cytokine imbalance in patients with lupus nephritis (LN) and its role in the pathogenesis. Methods Plasma level of interleukin-18 and interleukin-13 in 18 patients with active LN and 16 normal controls were measured by enzyme-linked immunoadsordent assay (ELISA). IL-18 and IL-13 expression in the renal tissues from 18 patients and 6 normal renal tissues were also detected by immunohistochemical assay. The ratio of plasma and renal IL-18/IL-13 was then calculated. Results Plasma levels and renal expression of IL-13 and IL-18 in patients with LN were increased significantly compared to those of normal controls (P<0.001 respectively). The ratio of plasma IL-18/IL-13 was increased significantly in patients with type Ⅳ LN compared to that of normal controls. It was decreased in patients with type Ⅴ LN and was not significantly different compared to normal controls (P>0.05). The ratio of renal IL-18/IL-13 was not significantly different among all types of LN and normal controls. The ratio of plasma IL-18/IL-13 was positively correlated with LN renal tissue activity index (AI), but no correlationship could be found in renal IL-18/IL-13 ratio. Conclusion It seems that the immune disturbance in systemic lupus erythematosus (SLE) can not be simply divided into Th1 predominant and Th2 predominant. It seems far complicated than this Th1/Th2 paradigm. It may be affected by the state of disease activity, the lesion location and the type of pathology.
