Clinical effect and safety of clopidogrel combined with aspirin in antithrombotic therapy for children with Kawasaki disease complicated by small/medium-sized coronary artery aneurysms / 中国当代儿科杂志

ABSTRACT

OBJECTIVE@#To study the clinical effect and safety of clopidogrel combined with aspirin in antithrombotic therapy for children with Kawasaki disease (KD) complicated by coronary artery aneurysm (CAA).@*METHODS@#A total of 77 KD children who were diagnosed with multiple small/medium-sized CAAs by echocardiography between January 2013 and June 2018 were enrolled. They were randomly divided into observation group with 38 children (treated with clopidogrel and aspirin) and control group with 39 children (treated with low-molecular-weight heparin and aspirin). All children were followed up regularly, and the first 3 months of the course of the disease was the observation period. The children were observed in terms of the change of the coronary artery and the incidence of complications.@*RESULTS@#At month 3 of follow-up, among the children in the observation group, 6 had normal coronary artery, 11 had coronary artery retraction, 19 had stable coronary artery, and 2 progressed to giant coronary aneurysm; among the children in the control group, 7 had normal coronary artery, 12 had coronary artery retraction, 19 had stable coronary artery, and 1 progressed to giant coronary aneurysm; there was no significant difference in the change of the coronary artery between the two groups (P>0.05). There were 2 cases of epistaxis and 6 cases of skin ecchymosis in the observation group, and 1 case of epistaxis and 7 cases of petechiae and ecchymosis at the injection site in the control group, and no other serious bleeding events were observed in either group.@*CONCLUSIONS@#Clopidogrel combined with low-dose aspirin is safe and effective in antithrombotic therapy for children with KD complicated by CAA.
