State-of-the-art of invasive Group A Streptococcus infection in children: protocol for a scoping review of the literature with a focus on predictors of invasive infection.

Abstract

Background: Invasive group A streptococcus infection (iGAS) is a serious, sometimes life-threatening condition, with high case fatality rates and high morbidity whose incidence is greatly increased in the last years. Despite the increasing importance and frequency of this condition, at the best of our knowledge, no previous reviews have been published focusing on the risk factors for the development of this condition and its early clinical features. This paper reports the study protocol for a scoping review that aims to analyze the early signs and clinical features of invasive group A streptococcus disease in children, to recognize the prodromal stage of the disease. Methods: Comprehensive research combining the terms pediatric and invasive group A streptococcus infection has been performed on PubMed and SCOPUS to identify potential eligible studies. The search strategy for PubMed will be available in this paper. Two reviewers will screen first the abstract and subsequently the full text to identify eligible articles according to the predefined inclusion criteria. Divergences between the reviewers will be resolved by discussion (with a third author if necessary). Two review authors will extract data independently, everyone on a different Excel spreadsheet. Each researcher will be blinded to the decision of the other researcher. When the process will be completed, in case of discordance, any disagreement will be identified and resolved through discussion (with a third author if necessary). Dissemination: The findings of this review will be published in a peer-reviewed journal.
