Autoimmune hemolytic anemia in a teenager: a wolf in sheep's clothing
Bibliographic record
Abstract
This case report describes a 14-year-old boy who presented to the emergency department with symptoms of severe anemia. He was diagnosed with autoimmune hemolytic anemia, and on further investigation, it was noted that he had no functioning T cells. Despite no antecedent history of severe infection, he was worked up for a severe combined immunodeficiency, and was found to have a compound hypomorphic mutation in an enzyme responsible for recombination of the B- and T-cell receptors. He was subsequently diagnosed with severe combined immunodeficiency, presenting with autoimmunity, and received a bone marrow transplant. As our knowledge of the immune system continues to expand, we are learning that dysregulation can occur in any one of the complex immune pathways, and may have a variety of clinical presentations. A high index of suspicion for immune defects should be maintained in cases of atypical or severe infections, autoimmunity or malignancy, particularly by the general practitioner, who is often the first to encounter these challenging patients.

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.
