A case report of fatal anaphylaxis on first exposure to rasburicase just before lymphoma treatment
Bibliographic record
Abstract
BACKGROUND: Rasburicase, a recombinant urate oxidase enzyme, has potent efficacy in controlling uric acid and is widely used to prevent tumor lysis syndrome in high-risk patients owing to its low toxicity profile. However, it has been associated with a risk of anaphylaxis, especially on re-exposure, owing to its immunogenic potential. CASE PRESENTATION: A 71-year-old Japanese female diagnosed with diffuse large B cell lymphoma with a large tumor burden experienced anaphylactic shock leading to death upon initial administration of rasburicase. The pre-and postmortem examination revealed that the cause of death was a cascade of events starting with anaphylaxis-induced distributive shock leading to obstructive shock due to the collapse of the heart, which was compressed by the post-mediastinal tumor. This was further compounded by massive bleeding from the tumor and tension hemothorax, resulting in circulatory collapse. CONCLUSIONS: Although extremely rare, rasburicase can cause fatal anaphylaxis, even on first exposure.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
