Checkpoint inhibitors are increasingly used to treat different types of malignancy and have been associated with renal toxicities. In this issue, Izzedine et al. report on the incidence of pembrolizumab-associated renal toxicity in a French single-centre nephrology referral centre. They report an estimated incidence of pembrolizumab-related renal toxicities of 1.77% and most notably the most common histologic lesion was acute tubular injury (not acute tubulo-interstitial nephritis). This study further highlights the importance of performing a thorough nephrological workup including kidney biopsy in patients experiencing renal toxicities while receiving pembrolizumab treatment.status: publishe
