Comparison of Efficacy and Safety of Different Preparations of Intravenous Human Immunoglobulin for Kawasaki Disease Treatment in Children
OBJECTIVE To investigate the efficacy and safety of different preparations of intravenous immunoglobulin(IVIG)for Kawasaki disease treatment in children.METHODS A retrospective analysis of medical records of pediatric Kawasaki disease patients at our institution in recent three years was conducted.Patients were divided into preparation A group and preparation B group based on the type of IVIG preparations used.Both groups received IVIG(2 g·kg-1)in conjunction with aspirin therapy following Kawasaki disease diagnosis.Changes in body temperature,white blood cell count,platelet count,C-reactive protein levels,IVIG cost,length of hospital stay,and adverse events were compared.RESULTS According to the drug labeling,there are certain differences between preparation A and preparation B.Preparation B exhibited a significantly shorter duration of fever resolution compared with preparation A(P<0.005),and at the first temperature test after infusion,the body temperature of preparation B group was signifi-cantly lower than that of preparation A group(P<0.05).Furthermore,preparation B demonstrated a more significant reduction in white blood cell count following treatment(P=0.010).In terms of hospital stay duration and IVIG monotherapy costs,preparation B had significantly shorter hospital stay(P<0.05)and lower per-unit IVIG expense(P<0.001).No significant differences were ob-served between the two groups in terms of adverse events,including rashes,infusion interruptions due to high fever,liver injury,and coronary dilation.CONCLUSION There is significant difference in efficacy between different preparations of intravenous immuno-globulin in the treatment of Kawasaki disease in children,but the safety is similar.
