摘要:

目的探讨系统性红斑狼疮(systemic lupus erythematosus,SLE)女性患者的免疫球蛋白G N-糖基(IgG N-糖基)与红细胞分布宽度(red blood cell distribution width,RDW)之间的关系,为后续SLE联合标志物提供理论基础。方法选取2018年10月—2020年5月在山东省聊城市人民医院风湿免疫科门诊确诊及住院的341例SLE女性患者为研究对象,采集血液样本进行血常规检测并提取纯化血浆IgG,采用超高液相色谱法检测血浆IgG N-糖基水平。IgG N-糖基与红细胞分布宽度的关联性分析采用Spearman秩相关与logistic回归分析。结果RDW高水平组中的半乳糖基化及唾液酸化水平显著低于RDW低水平组。logistic回归分析结果显示,GP12、GP14、GP18与GP23为RDW升高的保护因素,高水平的GP4与GP8为RDW升高的危险因素。结论SLE女性患者IgG N-糖基与RDW存在关联性,异常的IgG N-糖基化可能是影响RDW水平升高的因素,为后续二者联合指标对疾病进行早期诊断或反映疾病情况的研究提供了理论基础。

Abstract:

ObjectiveTo explore the relationship between immunoglobulin G N-glycans (IgG N-glycans) and red blood cell distribution width (RDW) in female patients with systemic lupus erythematosus (SLE), and to provide a theoretical basis for subsequent SLE combined markers.Methods341 female patients with systemic lupus erythematosus who were diagnosed and hospitalized in the Department of Rheumatology and Immunology of Hospital from October 2018 to May 2020 were selected as the research subjects. Blood samples were collected for routine blood testing and purified plasma IgG was extracted. Ultra-high liquid chromatography was used to detect plasma IgG N-glycosyl levels. Spearman rank correlation and logistic regression analysis were used for the correlation analysis between IgG N-glycans and the distribution width of red blood cells, andP< 0.05 was considered statistically significant.ResultsThe levels of galactosylation and sialylation in the high-level RDW group were significantly lower than those in the low-level RDW group. The results of logistic regression analysis showed that GP12, GP14, GP18, and GP23 were protective factors for elevated RDW, and high levels of GP4 and GP8 were risk factors for elevated RDW.ConclusionThere is a correlation between IgG N-glycosylation and RDW in female patients with SLE. Abnormal IgG N-glycosylation may be a factor that affects the increase in RDW levels, which provides a combination of indicators for the subsequent early diagnosis of the disease or the study of the disease’s theoretical basis.
