Abstract: Hemophagocytic lymphohistiocytosis (HLH) is a rare complication of chimeric antigen receptor T-cell (CAR-T) therapy [ 1 , 2 , 3 ]. With the increasing use of CAR-T therapy in treating hematological malignancies, the unique phenomenon of CAR-T-associated HLH (carHLH) is increasingly recognized. Albeit rare, reported rates vary from 1–3% to 35% depending on the underlying disease, patient population and the CAR-T product [ 1 , 2 , 3 ]. Recently ASTCT has published guidelines recognizing HLH in the setting of CAR-T as immune effector cell-associated HLH-like syndrome (IEC-HS) [ 4 ]. The most extensive series to date that comprehensively described manifestations, along with patient and CAR-T specific factors associated with the development of carHLH, is that of anti-CD22 CAR-T in 21 pediatric patients with B-ALL [ 2 ]. We herein provide a detailed description of clinical presentation, treatment strategies, and outcomes in adult patients who developed carHLH across three sites at Mayo Clinic.
