Abstract Objective: To observe the changes of serum interleukin-35 (IL-35) and C-C motif chemokine ligand 19 (CCL19) in children with systemic lupus erythematosus (SLE), and to analyze the association with immunological indexes. Methods: A total of 97 children with SLE in the hospital were included from January 2022 to March 2024, and 97 healthy children were selected for control study during the same time period. The changes of serum IL-35 and CCL19 levels were observed, and the correlation with immunological indexes [including anti-ds-DNA antibody, immunoglobulin (Ig), complements C3 and C4] was analyzed. Results: Compared with the healthy children, the children with SLE had a significantly lower serum IL-35 level and a significantly higher serum CCL19 level (P<0.05). Compared with the children with inactive SLE, serum levels of IL-35, C3, and C4 in the children with active SLE were significantly lower while serum levels of CCL19, anti-ds-DNA antibody, IgM, IgG, and IgA were significantly higher (P<0.05). Pearson correlation analysis showed that the serum level of IL-35 in children with SLE was negatively correlated with the levels of anti-ds-DNA antibody, IgM, IgG, and IgA, and was positively correlated with the levels of C3 and C4 (P<0.05). Serum CCL19 level was positively correlated with the levels of anti-ds-DNA antibody, IgM, IgG and IgA, and was negatively correlated with the levels of C3 and C4 in children with SLE (r=-0.314, -0.203, -0.301, -0.201, 0.318, 0.383, P<0.05). Linear regression analysis suggested that anti-ds-DNA antibody had a negative impact on IL-35 level in children with SLE (r=0.272, 0.209, 0.362, 0.202, -0.219, -0.391,P<0.05) while C3 had a positive impact on IL-35 level (P<0.05). IgG in children with SLE had a positive impact on CCL19 level (P<0.05). Conclusion: The abnormal changes of serum IL-35 and CCL19 levels in children with SLE are correlated with the levels of anti-ds-DNA antibody, IgM, IgG and IgA. There is a certain influence relationship between anti-ds-DNA antibody, C3 and IL-35, IgG and CCL19.
