Background: The human microbiome is crucial in regulating intestinal and systemic functions. While its role in cardiovascular disease is better understood, the link between intestinal microbiota and valvular heart diseases (VHD) remains largely unexplored.
Methods: Peer-reviewed studies on human, animal or cell models analysing gut microbiota profiles published up to April 2024 were included.
Introduction: The introduction of CAR-T cell treatment for relapsed/refractory (r/r) mantle cell lymphoma improved survival rates of these patients. Along with its introduction in clinical routine, long-term events after CAR-T cell treatment are increasingly emerging.
Case Presentation: We report the case of a patient developing acute erythroid leukemia with biallelic inactivation occurring 26 months after CAR-T therapy with brexucabtagene autoleucel (brexu-cel) for r/r mantle cell lymphoma.
