Abstract
Immune-related nephrotoxicity (ir-N) is a rare adverse event of immune-checkpoint(s) inhibitors (ICI) therapy and its clinical management is still debated. Among 501 consecutive ICI-treated patients at our Institution, 6 who developed an ir-N with clinical signs suggestive for an acute kidney injury underwent kidney biopsy. Histology showed an acute tubule-interstitial nephritis, simulating the scenario of acute T-cell–mediated kidney transplant rejection. Thus, the management of allograft kidney rejection routinely utilized at our clinic was implemented, leading to rapid renal function improvement. Histologic features supporting the definition of an immune-mediated acute kidney injury in ICI-treated patients may help optimizing the clinical management of ir-N.Keywords
