Background Despite the radiological and analytical advances of the last decades,there is still a significant rate of diagnostic error in pediatric acute appendicitis.In recent years,multiple biomarkers have emerged as potential diagnostic tools.This study aimed to examine the diagnostic performance of serum interleukin-6 in pediatric acute appendicitis.Methods We conducted a systematic review of the literature that involved an extensive search in the main databases of medical bibliography (Medline,PubMed,Web of Science and SciELO).Two independent reviewers selected the relevant articles based on the previously defined inclusion and exclusion criteria.Methodological quality of the selected article was rated using the QUADAS2 index.Data extraction was performed by two independent reviewers.Results The research in the medical bibliography databases resulted in 68 articles.We removed 26 duplicates.Among the remaining 42 articles,we excluded 33 following the inclusion and exclusion criteria.Of the final 9 studies included in this review,8 provided measured serum interleukin-6 values,and all of them reported significant differences between groups,but inconsistent results regarding sensitivity and specificity.Conclusions The diagnostic performance of interleukine-6 alone for the diagnosis of acute appendicitis in children is lim-ited.The sensitivity and specificity of interleukine-6 for the diagnosis of non-complicated acute appendicitis in the pediatric population are moderate but increased in complicated appendicitis.There seems to be a direct relationship between serum level of interleukin-6 and the hours of evolution of abdominal pain in children with acute appendicitis.The increasingly widespread use of non-operative management of acute appendicitis warrants further exploration of the classificatory potential of this marker between complicated and uncomplicated appendicitis.We consider that this may be an avenue of research to explore in the future.
