Unexpected Rasburicase-Induced Hemolysis in a Patient With Normal Glucose-6-Phosphate Dehydrogenase Activity
Bibliographic record
Abstract
Tumor lysis syndrome (TLS) presents significant challenges in oncology, primarily due to metabolic complications such as hyperuricemia, which can lead to acute kidney injury. Rasburicase, a recombinant urate oxidase, is frequently employed to manage hyperuricemia in TLS patients. However, its use is an absolute contraindication in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency due to the risk of hemolysis. In this case, the patient developed hemolytic anemia post-rasburicase administration even though she had normal G6PD activity, which was confirmed on two separate occasions, including during an acute episode and 3 months later. This case is unique as it documents hemolytic anemia induced by rasburicase in a patient without G6PD deficiency, challenging current understandings of the drug's safety profile. It suggests the need for caution and thorough screening before rasburicase use, even in patients considered low risk for G6PD deficiency. The report highlights the importance of close monitoring for adverse effects and the potential for alternative mechanisms of rasburicase-induced hemolysis.

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.
