Abstract
Serious bacterial infections (SBI) can lead to devastating complications with CD19 CAR T cells and cytokine release syndrome (CRS). Little is known about consequences of and risk factors for SBI with novel CAR T-cell constructs or with CRS complicated by HLH-like toxicities. We report on three patients with B-cell acute lymphoblastic leukemia treated with CD22 CAR T cells who developed SBI and CRS-associated HLH. Serum cytokine profiling revealed sustained elevations well beyond CRS resolution, suggesting ongoing systemic inflammation. Heightened inflammatory states converging with SBI contribute to poor outcomes, and recognition and prevention of extended inflammation may be needed to improve outcomes.Entities:
