“…Existing studies have demonstrated that the mechanism of ICIs-related renal injury supports the "multiple hit" or "brake release" theory, affecting the immune tolerance of T cells to renal intrinsic antigen (autoimmune-related) or concomitant drugs (drug-induced) in the presence of PD 1, PD L1, and CTLA 4 inhibitors, activated T cells in ltrate in the renal parenchyma, and release cytokines leading to renal injury [1] . Its main clinical manifestation is AKI; the most common pathological type is tubulointerstitial nephritis (TIN) [2] , and other pathological changes include thrombotic microangiopathy [3] , immune complex glomerulonephritis [4] , anti-GBM glomerulonephritis [5] , glomerular minimal change disease, membranous nephropathy, immune glomerulonephritis, and IgA nephropathy [6] . If the patient has elevated serum creatinine after receiving ICIs (the patient's serum creatinine level is 1.5 times higher than before ICI treatment [7] ), the possibility of ICI-related AKI should be considered in clinical diagnosis and treatment.…”
