Review: Infectious Esophagitis

JEM O’Donnell, U Krishnan. JPGN 2022; 75: 556-563.Infectious Esophagitis in Children

Key points:

  • Three most common causes of infectious esophagitis in children: Candida, HSV and CMV. Asperigillus (& other fungi) as well as bacterial esophagitis are rarely seen. Rare viral infections include human papilloma, varicella zoster and EBV
  • For Candida, this is typically a benign commensal organism but can become pathogenic due to changes in immunity (immunocompromised including corticosteroids), altered motility and sometimes after antibiotics (with or without PPI therapy). EoE can present with similar-appearing mucosa; thus, biopsy and/or brushing is needed.
  • With HSV, pediatric case series have reported higher rates in immunocompetent children
  • Typical treatments: fluconazole for Candida, and Acyclovir for HSV. For CMV, potential treatments include ganciclovir, valganciclovir, foscarnet or cidofovir.

My take: This is a short, good review of the infections that can cause esophagitis in children.

In a patient who presented with trouble swallowing, his endoscopy showed candida esophagitis.  “Oral antifungal therapy was initiated in the patient, and within 2 weeks after starting therapy, his pain on swallowing was reduced. A repeat endoscopy performed 12 weeks after the initiation of antifungal therapy showed a marked reduction in the number and severity of esophageal lesion.”
