[Changes in serum levels of adipokine after treatment in children with Kawasaki disease].

OBJECTIVE: To study the changes in the serum levels of Chemerin and Omentin-1 in children with Kawasaki disease (KD) in the acute stage after intravenous immunoglobulin (IVIG) treatment and related clinical significance. METHODS: A total of 60 children who were diagnosed with KD from January 2015 to April 2019 were enrolled as subjects. Forty healthy children and 40 children with acute infectious diseases were enrolled as the healthy control group and the infection control group respectively. According to the sensitivity to IVIG treatment, the children with KD were divided into an IVIG sensitive group with 51 children and a non-IVIG sensitive group with 9 children. According to the presence or absence of coronary artery lesion, the children with KD were divided into a CAL group with 13 children and a non-CAL group with 47 children. ELISA was used to measure the serum levels of Omentin-1 and Chemerin before and after the treatment. RESULTS: The children with KD had significantly higher serum levels of Chemerin and Omentin-1 than the healthy control and infection control groups before treatment (P<0.05). After 48 hours of treatment, the IVIG sensitive group had a significant reduction in the serum level of Chemerin (P<0.05), while there was no significant change in the serum level of Omentin-1 after treatment (P>0.05). Before treatment, the non-IVIG sensitive group had a significantly higher serum level of Chemerin than the IVIG sensitive group (P<0.05), and the CAL group had a significantly higher serum level of Chemerin than the non-CAL group, while there was no significant difference in the serum level of Omentin-1 between the IVIG sensitive and non-IVIG sensitive groups, as well as between the CAL and non-CAL groups (P>0.05). CONCLUSIONS: High serum levels of Chemerin and Omentin-1 may play an important role in the development and progression of KD. Chemerin may be involved in the development of CAL in children with KD. The serum level of Chemerin may be used as a new index for predicting the sensitivity to IVIG treatment.
