Background:Concerns have been raised about the efficacy of intravenous immunoglobulin and corticosteroids in pediatric myocarditis;however,the relationship between the risk and efficacy of these two therapies in children with myocarditis varies.Methods:A systematic review on seventeen studies was conducted in July 2020,which included 1,960 subjects at the baseline,with 788 receiving intravenous immunoglobulin and 142 receiving corticosteroids.The mean difference(MD)or odds ratio(OR)with 95%confidence intervals(Cis)was calculated to assess the prognostic role of both treatments using dichotomous and continuous methods with random or fixed-effect models.Results:The use of intravenous immunoglobulin was significantly associated with a lower mortality rate or heart transplantation in children with myocarditis(OR,0.55;95%CI,0.40-0.77,^<0.001)compared with the control group.However,corticosteroids were not significantly associated with the same parameters(OR,0.72;95% CI,0.31-1.63,p=0.43).The use of intravenous immunoglobulin was not significantly related to improving left ventricular ejection in children with myocarditis(OR,2.30;95% CI,-9.65-14.25,p=0.71)and so were corticosteroids(MD,5.17;95% CI,-0.26-10.60,p=0.06).Conclusion:The use of intravenous immunoglobulin might have an independent risk relationship with a lower mortality rate or heart transplantation and is recommended in children with myocarditis to prevent complications.
