Clinical Presentation and Diagnosis of Drug Reaction with Eosinophilia and Systemic Symptoms (DReSS) in Children: A Scoping Review.

Abstract

Effective treatment of drug reactions with eosinophilia and systemic symptoms (DReSS) requires early diagnosis and close monitoring. Diagnosing DReSS is especially challenging in children due to a low incidence rate, heterogeneous clinical presentation, and a lack of (pediatric) diagnostic criteria and clinical practice guidelines. We performed a scoping review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to summarize the clinical presentation and diagnostic process of DReSS in children (aged 0-18years). Data from 644 individuals showed that DReSS manifests differently in children compared to adults. Children have a higher number of organs involved, including higher rates of cardiac and respiratory involvement compared to adults. Children < 6years of age appear more prone to develop neurologic symptoms. Conversely, eosinophilia, edema, and kidney involvement are less frequently observed in children. Anti-seizure medications are by far the most common causative drug class, but the range of implicated drugs increases as children get older. This study highlights that children with DReSS not only differ from adults but also that differences exist between children of different ages. As such, there is a need to establish pediatric-specific diagnostic criteria. These efforts will promote earlier diagnosis of DReSS and likely lead to improved clinical care offered to children and their families.
