弥漫大B细胞淋巴瘤患者外周血白细胞介素6、白细胞介素8和白细胞介素10的表达及其临床意义

Expressions of interleukin 6,interleukin 8 and interleukin 10 in the peripheral blood of patients with diffuse large B-cell lymphoma and their clinical significances

目的探讨弥漫大B细胞淋巴瘤(DLBCL)患者外周血中白细胞介素6(IL-6)、白细胞介素8(IL-8)和白细胞介素10(IL-10)的表达及其临床意义。方法回顾性分析2018年3月至2021年3月厦门大学附属第一医院78例初治DLBCL患者的临床资料,选取同期58名健康体检者作为健康对照。采用流式微球捕获芯片技术(CBA)检测受试者外周血中IL-6、IL-8和IL-10表达水平,并分析DLBCL患者这些指标与临床特征、疾病分期和预后的关系。结果DLBCL组IL-6、IL-8和IL-10表达水平均高于健康对照组[(171.81±70.91)pg/ml比(2.71±0.28)pg/ml,(47.95±13.04)pg/ml比(3.69±0.47)pg/ml,(38.02±10.35)pg/ml比(1.77±0.23)pg/ml],差异均有统计学意义(t值分别为2.38、3.39、3.50,均P<0.05)。DLBCL患者中,骨髓侵犯、国际预后指数(IPI)评分3~5分及临床分期Ⅲ~Ⅳ期患者的IL-6、IL-8和IL-10水平均高于骨髓未侵犯、IPI评分1~2分及临床分期Ⅰ~Ⅱ期患者(均P<0.05)。DLBCL患者外周血中IL-6与IL-8、IL-6与IL-10、IL-8与IL-10表达水平均相关(r2值分别为0.93、0.89、0.89,均P<0.05)。IL-6、IL-8、IL-10均高表达的患者中,临床分期为Ⅲ~Ⅳ期、6个疗程后未缓解患者比例均高于IL-6、IL-8、IL-10单项及两项高表达患者,差异均有统计学意义(均P<0.05)。结论DLBCL患者外周血清中IL-6、IL-8和IL-10表达水平具有较高的相关性,三者表达水平升高预示DLBCL患者疾病分期较晚、预后较差。

Objective To explore expressions of interleukin 6(IL-6),interleukin 8(IL-8)and interleukin 10(IL-10)in the peripheral blood of patients with diffuse large B-cell lymphoma(DLBCL)and their clinical significances.Methods The clinical data of 78 newly diagnosed patients with DLBCL from March 2018 to March 2021 in the First Affiliated Hospital of Xiamen University were retrospectively analyzed,and 58 healthy people receiving physical examination during the same period were taken as the healthy controls.The expressions levels of IL-6,IL-8 and IL-10 in peripheral blood were tested by using cytometric bead array(CBA),and the association of the levels of IL-6,IL-8 and IL-10 with clinical characteristics,disease staging and prognosis was analyzed.Results The expression levels of IL-6,IL-8 and IL-10 in DLBCL group were higher than those in the healthy control group[(171.81±70.91)pg/ml vs.(2.71±0.28)pg/ml,(47.95±13.04)pg/ml vs.(3.69±0.47)pg/ml,(38.02±10.35)pg/ml vs.(1.77±0.23)pg/ml],and differences were statistically significant(t values were 2.38,3.39,3.50,all P<0.05).In DLBCL group,the expression levels of IL-6,IL-8 and IL-10 in patient with bone marrow invasion,international prognostic index(IPI)3-5 scores and clinical stagingⅢ-Ⅳwere higher than those in patients with bone marrow non-invasion,IPI 1-2 scores and clinical stagingⅠ-Ⅱ(all P<0.05).There was a relationship between the expression levels of IL-6 and IL-8,IL-6 and IL-10,IL-8 and IL-10 in peripheral blood of DLBCL patients(r2 value was 0.93,0.89,0.89,respectively;all P<0.05).Among patients with high expressions of IL-6,IL-8 and IL-10,the proportion of patients not receiving remission after 6 cycles of treatment in clinical stagingⅢ-Ⅳwas higher than that of patients with high expressions of IL-6,IL-8 and IL-10 alone or any two of them,and differences were statistically significant(all P<0.05).Conclusions There is a high correlation of IL-6,IL-8 and IL-10 expression levels;the increasing expression levels of them may predict the later disease stage and poor prognosis for DLBCL patients.
