Bone Marrow Aplasia after CAR-T-Cell Therapy for Relapsed/Refractory Burkitt's Lymphoma.

Chimeric antigen receptor T-cells (CAR-T) are now a standard approach for treating relapsed/refractory B-cell lymphomas. Immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome (IEC-HS) is a newly described entity that can manifest following CAR-T. Bone marrow (BM) aplasia is an uncommon manifestation of IEC-HS reported after CAR-T-cell therapy and is defined as the reduction or absence of hematopoietic progenitor cells resulting in severe pancytopenia.

Higher Weight-Based Doses Are Required to Achieve and Maintain Therapeutic Voriconazole Serum Trough Concentrations in Children.

Objective: Children require weight-based voriconazole doses proportionately larger than adults to achieve therapeutic serum trough concentrations (1-6 mcg/mL). The objective of this quality improvement project was to determine the initial dose, proportion of patients achieving target concentrations with initial dosing, and subsequent therapeutic drug monitoring and dose modifications needed to achieve and maintain therapeutic voriconazole concentrations in children.

Methods: This retrospective study evaluated children aged <18 years treated with voriconazole during the study period.
