Acute Kidney Injury Associated with Novel Anticancer Therapies: Immunotherapy.

The landscape of cancer survival has been positively affected by the introduction and dissemination of immunotherapy with the wide usage of immune checkpoint inhibitors and chimeric antigen receptors cell therapies. The success of these novel therapies can, however, be limited to a certain extent by systemic inflammatory toxicities affecting, directly or indirectly, the kidney. In the case of immune checkpoint inhibitors, severe acute interstitial nephritis is the main adverse event and can lead to permanent discontinuation of the therapy. In turn, chimeric antigen receptor cell therapy can cause cytokine release syndrome and immune effector cell-associated hemophagocytic lympho-histiocytosis, with kidney damage through various mechanisms, and be life threatening. Prompt diagnosis and management of these entities is essential to preserve kidney function and ensure the best possible kidney and overall outcomes to patients with cancer.
