- Abstract
The pathophysiology of AKI during tumor lysis syndrome (TLS) is not fully understood. We aimed to decipher crystal-dependent and crystal-independent mechanisms of TLS-induced AKI. Analyzing urine and blood from patients with TLS provided data on crystal-independent mechanisms of the pathogenesis of AKI during TLS. We also explored mechanisms of TLS-induced AKI in vitroand in vivoin a murine model of TLS (syngeneic mice with acute myeloid leukemia receiving chemotherapy). We found that extracellular histones released in huge amounts during TLS profoundly alter the endothelium. Nonanticoagulant heparin mitigated AKI in this model.
