Risk analysis of cardiovascular toxicity in patients with lymphoma treated with CD19 CAR T cells
Bibliographic record
Abstract
BACKGROUND: Anti-CD19 chimeric antigen receptor (CAR) T cell therapy is a common, yet highly efficient, cellular immunotherapy for lymphoma. However, many recent studies have reported on its cardiovascular (CV) toxicity. This study analyzes the cardiotoxicity of CD19 CAR T cell therapy in the treatment of lymphoma for providing a more valuable reference for clinicians. METHODS: The PubMed, Embase, Cochrane library, and Web of Science databases were comprehensively searched from the time of their establishment to May 2024. The ClinicalTrials.gov English database is a comprehensive repository of the original studies of CD19 CAR T cell therapy and associated adverse outcomes, such as arrhythmia, CV events, and hypotension, in patients with lymphoma. The Cochrane Collaboration tool and the Newcastle-Ottawa Scale (NOS) were used to assess the quality of the included original studies. For RCTs, the Cochrane Collaboration tool was used to assess the risk of bias. For non-randomized studies, the risk of bias was assessed using the NOS quality assessment scale. RESULTS: A risk analysis of two randomized controlled trials and nine cohort studies, totaling 1379 patients with lymphoma receiving CD19 CAR-T, is conducted. The incidences for all-cause mortality, CV events, and hypotension were found to be 17.8%, 17.8%, and 52.8%, respectively. Additionally, the incidences of heart failure (HF), cardiomyopathy, cardiac arrest, and other CV events are 3%, 0.6%, 1.3%, and 2.5%, respectively. In addition to cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) as adverse events, patients treated with CD19 CAR T cells are also at risk of CV events. The most common CV events are arrhythmia and HF. Our further analysis showed that the incidence of CV events was 28.7% in the elderly and 13.5% in adults. The incidence of CV events in the elderly was higher than that in adults, and it was statistically significant. Furthermore, the incidence of CV events and hypotension is strongly associated with patients with CRS. CONCLUSION: Therefore, clinicians should pay close attention to the occurrence of such CV events and take timely prevention and intervention measures to further improve the safety of CD19 CAR T cell therapy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
