Early recognition of life-threatening otolaryngologic complications in pediatric epstein-barr virus infectious mononucleosis: a systematic review and meta-analysis

Year: 2026

Type: review

Study designs: Systematic Review, Meta-Analysis

Abstract: Objective: To systematically synthesize evidence on life-threatening otolaryngologic (ENT) complications of pediatric Epstein-Barr virus (EBV) infectious mononucleosis (IM), quantify clinically compatible upper-airway outcomes, assess certainty, and develop a cautious evidence-informed clinical framework. Methods: PubMed/MEDLINE was searched from January 1, 1990 to September 8, 2026 in accordance with PRISMA 2020. Eligible English-language observational studies and case series included at least four patients and reported severe ENT manifestations of EBV-IM. Evidence was classified as direct pediatric when the analyzed cohort was restricted to patients aged ≤18 years and as mixed-age supportive when relevant pediatric/adolescent observations were embedded within a broader age range and could not be fully separated. Mixed-age studies did not contribute to the primary pediatric meta-analysis. Design-specific JBI tools and outcome-level GRADE were used. Quantitative pooling was restricted to studies with clinically compatible populations, denominators, and outcome definitions. Results: = 0.091; k = 3). Suppurative/deep neck complications, candidate warning features, biomarkers, imaging findings, and treatment effects were not pooled because populations, denominator directions, sampling frames, or outcome definitions were incompatible. Certainty was low that UAO is a clinically important complication in hospitalized pediatric IM and very low for the pooled numerical proportion and the remaining evidence streams. Conclusions: UAO is the most consistently documented life-threatening ENT manifestation of pediatric EBV-IM, while suppurative/deep neck complications are clinically important but quantitatively heterogeneous. By separating directly pediatric evidence from mixed-age supportive data and preserving outcome-specific denominators, this review provides a structured synthesis of the limited evidence to support clinical awareness and hypothesis generation, while defining priorities for prospective pediatric validation.
