Checkpoint inhibitor therapy-associated acute kidney injury: time to move on to evidence-based recommendations

Tijdschriftbijdrage - Tijdschriftartikel

Immune checkpoint inhibitors (ICIs) have revolutionized cancer treatment since their introduction ∼15 years ago. However, these monoclonal antibodies are associated with immune-related adverse events that can also affect the kidney, resulting in acute kidney injury (AKI), which is most commonly due to acute tubulointerstitial nephritis (ATIN). Limited data are available on the true occurrence of ICI-associated AKI. Furthermore, evidence to guide the optimal management of ICI-associated AKI in clinical practice is lacking. In this issue, Oleas et al. report a single-center study of patients with nonhematologic malignancies who received ICI treatment during a 14-month period, experienced AKI and underwent a kidney biopsy at the Vall d'Hebron University Hospital. Importantly, they demonstrate that only a minority of ICI-associated AKI patients was referred to the nephrology service and kidney biopsy was only performed in 6.4% of patients. Although the authors add to our knowledge about ICI-associated AKI, their article also highlights the need for the development of noninvasive diagnostic markers for ICI-associated ATIN, the establishment of treatment protocols for ICI-associated ATIN and recommendations for optimal ICI rechallenge in patients with previous ICI-associated AKI.
