Increased complications and morbidity in children with hemophagocytic lymphohistiocytosis undergoing hematopoietic stem cell transplantation
Bibliographic record
Abstract
BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is the only curative option for patients with primary hemophagocytic lymphohistiocytosis (HLH) and for patients with secondary HLH who fail to respond to therapy. METHODS: Retrospective study of HSCT for HLH with focus on complications and outcome. RESULTS: Eighteen children (10 males), with a median age of 1.2 yr (5 months-16 yr), received HSCT for HLH. Fourteen children had primary HLH. Four children underwent transplant while not in remission. Sixteen received myeloablative and two received reduced intensity conditioning regimen. A high incidence of complications was found: 13 (72%) children had 22 episodes of culture-proven infections; seven (38%) had hepatic veno-occlusive disease; nine (50%) developed respiratory complications; and nine (50%) required intensive care unit admission. Eight children had acute graft-versus-host disease (GVHD), and three developed chronic GVHD. Three patients died from multi-organ failure before day +100, and another patient died from pulmonary hemorrhage after day 100. Three patients failed to engraft (two developed recurrent HLH and died from complications after a second HSCT). Three of four children not in remission at the time of transplantation died. Actuarial survival at three yr was 61%. CONCLUSION: HSCT for HLH carries significant risks with high infection, organ dysfunction, and ICU admissions rates.

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.
