Successful Liver Transplants for Liver Failure Associated With Pyruvate Kinase Deficiency
Bibliographic record
Abstract
Pyruvate kinase deficiency (PKD) is the most common cause of congenital nonspherocytic chronic hemolytic anemia, and patients normally present with mild to severe anemia, unconjugated hyperbilirubinemia, and splenomegaly. Only a few reports of PKD have documented its association with severe, progressive liver failure. In all those cases, the patients died before liver transplant (LT) or immediately after transplant. We report 2 case patients with liver failure associated with PKD who successfully underwent LT and splenectomy: an infant who presented with neonatal cholestasis and a young adult with a severe form of PKD and having been transfusion dependent during childhood. After transplant, both patients have normal liver function test results and have considerably decreased their need for blood transfusion despite ongoing, mild hemolysis. We suggest that PKD can lead to severe liver dysfunction and that LT and splenectomy can be life-saving procedures in such cases.

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.
