Cardiac Chamber Hypertrophy following Hematopoietic Stem Cell Transplantation for Primary Immunodeficiency
Bibliographic record
Abstract
Children with primary immune deficiency (PID) who receive hematopoietic stem cell transplantation (HSCT) often suffer from graft-versus-host disease (GVHD), which is commonly treated with corticosteroids (CS). CS may cause hypertension, development of cardiac chamber hypertrophy (CCH), and left ventricular outflow tract obstruction (LVOTO). We followed the development of CCH and LVOTO by serial echocardiograms in 10 children with PID before and 6 to 12 weeks after HSCT, and correlated their development with age of transplant, GVHD, use of CS and hypertension. CCH developed in all 4 children transplanted before 1 year of age who received high dose CS treatment for grade III or IV acute GVHD (aGVHD), but not in the 6 children who were transplanted at later ages or who had not received high-dose CS (P = .07). Significant correlation (P < .002) was found between CCH and blood pressure measurements that deviated above the 99th percentile. One child also suffered from severe LVOTO. CCH and LVOTO improved when CS treatment was discontinued and blood pressure normalized. We conclude that following HSCT, young children who suffer from aGVHD, treated with high CS doses, and have excessive hypertension are at risk of developing CCH.

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.
