Abstract:
Immune checkpoint inhibitors have been approved for a variety of cancer species. Renal complications in use of these agents are not very common compared with other immune-related adverse events (irAE). However, it is crucial for physicians to recognize and manage renal manifestations of irAE. In this review, we will summarize the up-to-date knowledge of the clinical presentation, pathologic features, and management of renal irAE. In addition, we will discuss the safety of immune checkpoint inhibitors in patients with chronic kidney disease as well as in kidney transplant recipients.
Insights
Immune checkpoint inhibitors can cause rare kidney problems. This review covers how to identify, manage, and prevent these immune-related adverse events (irAE), including in patients with existing kidney disease.
Area of Science:
- Oncology
- Nephrology
- Immunology
Background:
- Immune checkpoint inhibitors (ICIs) are increasingly used for various cancers.
- Renal immune-related adverse events (irAEs) are uncommon but significant complications of ICIs.
- Early recognition and management of renal irAEs are crucial for patient outcomes.
Purpose of the Study:
- To provide a comprehensive review of renal irAEs associated with ICIs.
- To summarize current knowledge on clinical presentation, pathology, and management strategies.
- To discuss ICI safety in patients with pre-existing chronic kidney disease and kidney transplant recipients.
Main Methods:
- Literature review of clinical studies and case reports on renal irAEs.
- Analysis of data on incidence, clinical features, and histopathology.
- Synthesis of current guidelines and expert opinions on management.
Main Results:
- Renal irAEs manifest in diverse clinical and pathological patterns.
- Prompt diagnosis and appropriate immunosuppressive therapy can lead to favorable outcomes.
- Specific considerations are necessary for managing patients with chronic kidney disease and transplant recipients.
Conclusions:
- Renal irAEs are a manageable toxicity of ICIs.
- Physicians must be vigilant in monitoring for and treating renal complications.
- Further research is needed to optimize ICI use in vulnerable kidney populations.
