Clinical significance of changes of serum cytokines in children with Kawasaki disease / 中华实用儿科临床杂志

ABSTRACT

Objective:To summarize the changes of serum cytokines in 301 children with Kawasaki disease(KD) and analyze their clinical significance.Methods:Three hundred and one pediatic patients with KD admitted to Beijing Children′s Hospital, Capital Medical University between June 2018 and July 2019 were enrolled and divided into the immunoglobulin sensitive group and immunoglobulin non-response group according to the therapeutic effect.The levels of interferon gamma (IFN-γ), tumor necrosis factor-alpha (TNF-α), interleukin-10 (IL-10), interleukin-6 (IL-6), interleukin-4 (IL-4), and interleukin-2 (IL-2) were compared between the 2 groups.Results:(1)Fifty (16.6%) children had no-response to immunoglobulin.Before treatment, the level of serum cytokines in the immunoglobulin non-response group and the immunoglobulin sensitive group were as follows: IFN-γ[11.32(10.88) ng/L vs. 4.52(5.09) ng/L], TNF-α[7.43(11.25) ng/L vs. 4.42(6.04) ng/L], IL-10[14.44(20.3) ng/L vs. 8.32(7.99) ng/L], IL-6[100.28(126.39) ng/L vs. 41.34(49.32) ng/L], IL-4[1.06(1.79) ng/L vs. 0.98(1.42) ng/L], IL-2[0.48(0.90) ng/L vs. 0.40(0.62) ng/L]; there were significant differences in IFN - γ, TNF - α, IL-10 and IL-6 between the 2 groups (all P<0.05); there was no significant difference of IL-4 and IL-2 between the 2 groups (all P>0.05). (2)Before treatment and after the temperature was normal, the levels of cyto-kines in the immunoglobulin non-response group were as follows: IFN-γ[11.32(10.88) ng/L vs. 1.26(2.10) ng/L], TNF-α[7.43(11.25) ng/L vs. 1.52(3.46) ng/L], IL-10[14.44(20.3) ng/L vs. 4.63(7.00) ng/L], IL-6[100.28(126.39) ng/L vs. 22.85(39.95) ng/L], IL-4[1.06(1.79) ng/L vs. 0(0.25) ng/L], IL-2[0.48(0.90) ng/L vs. 0(0.02) ng/L]. Before treatment and after the temperature was normal, the levels of cytokines in the immunoglobulin sensitive group were as follows: IFN-γ[4.52(5.09) ng/L vs. 0.79(1.53) ng/L], TNF-α[4.42(6.04) ng/L vs. 1.60(3.4) ng/L], IL-10[8.32(7.99) ng/L vs. 3.59(3.74) ng/L], IL-6[41.34(49.32) ng/L vs. 11.90(18.84) ng/L], IL-4[0.98(1.42) ng/L vs. 0(0.88) ng/L], IL-2[0.40(0.62) ng/L vs. 0(0.14) ng/L]. The levels of cytokines decreased significantly after treatment in between 2 groups (all P<0.05). (3) Logistic regression analysis showed that IFN-γ, IL-6, fever duration and albumin were independent risk factors for no-response to immunoglobulin. Conclusions:Children with abnormally high serum IFN-γ and IL-6 levels before treatment are more likely to resist immunoglobulin.Therefore, the change of the condition in such children should be closely monitored.If there is no response to immunoglobulin, immunoglobulin should be used again as soon as possible or second-line drugs should be applied to improve the prognosis.
