幼年型复发性呼吸道乳头状瘤病中抑制性细胞因子与疾病严重程度的相关性研究

Correlation between inhibitory cytokines and disease severity in juvenile onset recurrent respiratory papillomatosis

目的探讨免疫调节性细胞因子在幼年型复发性呼吸道乳头状瘤病(juvenile onset recurrent respiratory papillomatosis,JORRP)患者外周及病变局部的表达变化,分析其与JORRP疾病严重程度的相关性。方法采集JORRP患者外周血,同时采集性别、年龄相匹配的健康儿童的外周血作为对照组;收取JORRP患者病变组织,同时采集扁桃体切除术患者的扁桃体前腭舌弓黏膜上皮组织作为对照组。ELISA检测血浆样本中细胞因子浓度,并对组织样本进行mRNAseq检测及RT-PCR验证分析。进一步将细胞因子表达水平和疾病严重程度进行相关性分析。结果JORRP患者血浆中白细胞介素10(IL-10)浓度显著高于对照组(P<0.05),且患者血浆中IL-10表达与初次发病年龄呈负相关(r=-0.3307,P<0.05)。IL-10 mRNA表达水平在侵袭性组较非侵袭性组显著升高(P>0.05)。JORRP患者血浆TGF-β浓度与采样时手术次数呈正相关(r=0.5144,P<0.05),且侵袭性组TGF-β浓度较非侵袭性组显著增高(P<0.05)。TGF-βmRNA表达水平在JORRP患者较对照组显著增高(P<0.001)。结论JORRP患者中抑制性免疫调节因子IL-10和TGF-β高表达且与疾病严重程度正相关。

OBJECTIVE Aims to investigate the expression changes of immunoregulatory cytokines in peripheral blood and local lesions of patients with juvenile onset recurrent respiratory papillomatosis(JORRP),and analyze their correlation with the severity of JORRP.METHODS Peripheral blood samples were collected from JORRP patients,along with peripheral blood samples from healthy children matched for gender and age as the control group.Papillomas of JORRP patients were collected,and the epithelial tissue from the palatine tonsils of patients undergoing tonsillectomy served as a control.ELISA was used to detect cytokine concentrations in plasma samples.The tissue samples were detected by mRNAseq and verified by RT-PCR.Furthermore,the correlation between cytokine expression levels and disease severity was analyzed.RESULTS The concentration of interleukin-10(IL-10)in the plasma of JORRP patients was significantly higher than that in the healthy control group(P<0.05),and it was negatively correlated with the age of onset(r=-0.3307,P<0.05).At the level of mRNA,the relative quantity of IL-10 in papillomas was significantly higher in the aggressive group compared to the non-aggressive group(P>0.05).Additionally,the concentration of TGF-βin plasma of JORRP patients was positively correlated with the number of surgeries(r=0.5144,P<0.05),and the concentration of TGF-βin the aggressive group was significantly higher than that in the non-aggressive group(P<0.05).The TGF-βmRNA expression level was significantly higher in the papillomas of JORRP patients compared to the control(P<0.001).CONCLUSION Inhibitory immunoregulatory cytokines IL-10 and TGF-βare overexpressed in JORRP patients and positively correlated with disease severity.
