Autoimmune hemolytic anemia associated with the use of immune checkpoint inhibitors for cancer: 68 cases from the Food and Drug Administration database and review.

Background: Immune checkpoint inhibitors (CPI) are widely used in modern oncology and have improved the prognosis of lung cancer, malignant melanoma, and other malignancies. Unlike cytotoxic chemotherapy, drugs such as nivolumab, pembrolizumab, and ipilimumab are associated with immune-related adverse effects. We recently observed a patient with lung cancer who developed a fulminant warm antibody autoimmune hemolytic anemia (AIHA).
