Abstract

Background: Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment and have become an essential part of therapy, but their use is associated with immune-related adverse events (irAE). Specifically, nephrotoxicity is well documented in adult populations but data regarding irAEs are limited in pediatric populations. This review examines the renal manifestations of ICIs and relevant clinical measures and treatments.
Materials and methods: A comprehensive review of existing literature was conducted to assess the incidence, pathophysiology, and management of ICI-associated renal injuries in pediatric and adult populations.
Results: The most common renal irAE associated with ICIs is acute kidney injury; however, ICIs have been implicated in transplant rejection and electrolyte disturbances including hyponatremia, hyperkalemia, hypophosphatemia, and metabolic acidosis. Pediatric ICI manifestation patterns are similar to those in adults, but research suggests earlier onset compared to adults. Though corticosteroids are the primary treatment for irAEs, standardized pediatric management guidelines require further improvement.
Conclusion: ICIs carry concerning risks in pediatric populations, yet research in this area is lacking. This warrants further research into the recognition, treatment, and prevention of renal irAEs, particularly for the improvement of long-term outcomes.
