摘要:

目的 探讨系统性红斑狼疮(SLE)患儿血清25-羟基维生素D3[25(OH)D3]水平与淋巴细胞亚群的关系。方法 选取2022年6月—2023年6月海南省妇女儿童医学中心SLE患儿52例(SLE组)和健康体检儿童50名(正常对照组)。检测所有研究对象血清25(OH)D3水平和淋巴细胞亚群[CD3+T细胞、CD4+T细胞、CD8+T细胞、总B细胞、自然杀伤(NK)细胞百分比和CD4+/CD8+比值]。参考维生素D缺乏标准将SLE患儿分为维生素D不足组[20例,25(OH)D3<50 nmol·L-1]和维生素D正常组[32例,25(OH)D3≥50 nmol·L-1]。采用Pearson相关分析评估血清25(OH)D3水平与淋巴细胞亚群的相关性。结果 SLE组血清25(OH)D3水平和CD4+T细胞百分比、CD4+/CD8+比值、NK细胞百分比、总B细胞百分比均低于正常对照组(P<0.05),CD3+T细胞百分比和CD8+T细胞百分比高于正常对照组(P<0.05)。维生素D不足组CD4+T细胞百分比、NK细胞百分比、总B细胞百分比和CD4+/CD8+比值均低于维生素D正常组(P<0.01),CD3+T细胞百分比和CD8+T细胞百分比高于维生素D正常组(P<0.05)。SLE患儿血清25(OH)D3与CD4+T细胞、CD4+/CD8+比值、NK细胞和总B细胞均呈正相关(r值分别为0.455、0.579、0.574、0.448,P<0.001),与CD3+T细胞、CD8+T细胞均呈负相关(r值分别为-0.574、-0.466,P<0.001)。结论 SLE患儿血清25(OH)D3水平与淋巴细胞亚群有关,提示维生素D水平可能在SLE的诊治中有一定的价值。

Abstract:

Objective To investigate the relationship between serum 25-hydroxyvitamin D3 [25(OH)D3] level and lymphocyte subsets in children with systemic lupus erythematosus (SLE). Methods A total of 52 children with SLE (SLE group) and 50 healthy children (healthy control group) were enrolled from Hainan Women and Children's Medical Center from June 2022 to June 2023. Serum 25(OH)D3 level and lymphocyte subsets [CD3+T cells,CD4+T cells,CD8+T cells,total B cells,natural killer(NK)cell percentage and CD4+/CD8+ratio] were determined. According to the vitamin D deficiency standard,SLE children were classified into vitamin D deficiency group [20 cases,25(OH)D3<50 nmol·L-1] and vitamin D normal group [32 cases, 25(OH)D3≥50 nmol·L-1]. The correlation between serum 25(OH)D3 level and lymphocyte subsets was evaluated by Pearson correlation analysis. Results The serum 25(OH)D3 level,CD4+T cell percentage,CD4+/CD8+ ratio,NK cell percentage and total B cell percentage in SLE group were lower than those in healthy control group(P<0.05),and the percentages of CD3+T cells and CD8+T cells were higher(P<0.05). The percentages of CD4+T cells,NK cells,total B cells and CD4+/CD8+ ratio in vitamin D deficiency group were lower than those in vitamin D normal group(P<0.01),and the percentages of CD3+T cells and CD8+T cells were higher(P<0.05). Serum 25(OH)D3 was positively correlated with CD4+T cells,CD4+/CD8+ ratio,NK cells and total B cells in SLE children(r values were 0.455,0.579,0.574 and 0.448,P<0.001). It was negatively correlated with CD3+T cells and CD8+T cells (r values were -0.574 and -0.466,P<0.001). Conclusions Serum 25(OH)D3 level is associated to lymphocyte subsets in children with SLE,suggesting that vitamin D levels may have diagnostic and therapeutic value in the diagnosis and treatment of SLE.
