Thyroid Dysfunction in Children Exposed to Iodinated Contrast Media:A Meta-Analysis and Systematic Review

摘要

Iodinated contrast media(ICM)has the potential to cause thyroid dysfunction in some patients.However,it is unclear whether this relationship exists in children.We conducted a systematic review and meta-analysis aim to obtain a general overview of the relationship between ICM exposure and the risk of thyroid dysfunction in children.Methods:Computer search of Web of Science,EMbase,PubMed,Cochrane Library,collection of relevant literature on ICM and thyroid dysfunction in children,the search period was from the establishment of the database to July 2021.Meta-analysis was performed using Stata 14.0 software.Results:A total of 8 literatures with 3497 children.The incidence of hypothyroidism in children with ICM exposure was 0.05(95%CI:0.05,0.12),P<0.0001.Subgroup analysis showed that the incidence of hypothyroidism in ICM exposed children in the European region was 0.21(95%CI:0.13,0.30),P<0.0001,a statistically significant difference.Conclusion:The current evidence shows that children exposed to ICM are at risk for hypothyroidism,with a higher risk in neonates,especially children with congenital heart disease.
