Kidney Adverse Events Associated with Immune Checkpoint Inhibitor Therapy: A Systematic Review and Bayesian Network Meta-Analysis.

Background: The blockade of immune regulatory sites, cytotoxic T-lymphocyte antigen 4, programmed cell death 1 (PD-1), and programmed cell death ligand 1 (PD-L1) with immune checkpoint inhibitors has revolutionized survival outcomes in patients with cancer. However, immune checkpoint inhibitors are associated with a range of immune-related adverse events. The aim of this network meta-analysis was to evaluate severe adverse kidney events in patients with oncological or hematological malignancy receiving monotherapy, dual therapy, or combined therapy treatment with immune checkpoint inhibitors when compared with either placebo or standard chemotherapy.
