Childhood Immune Thrombocytopenia: A Changing Therapeutic Landscape
Bibliographic record
Abstract
Childhood immune thrombocytopenia (ITP) is generally a benign self-limiting disorder of young children with <10% of cases requiring regular platelet enhancing therapy at 1 year following diagnosis. Increasingly, children with newly diagnosed ITP, who have isolated thrombocytopenia and no atypical features in the history or physical examination, are managed with minimal investigation and observation alone. The role of up-front, short-course corticosteroid therapy without bone marrow aspiration in this subgroup of cases merits further investigation. For children with clinically significant chronic ITP, the timing of elective splenectomy and the role of splenectomy-sparing strategies such as rituximab continues to be debated. Management of children with combined autoimmune cytopenias secondary to systemic lupus erythematosus, common variable immunodeficiency, and the autoimmune lymphoproliferative syndrome is often a challenge. Splenectomy should be avoided in cases with documented immunodeficiencies because of the increased risk of overwhelming sepsis postsplenectomy. For these cases, as well as for children with resistant primary chronic ITP who have failed splenectomy, the role of therapies such as mycophenolate mofetil, sirolimus, and the thrombopoietins remains to be determined.

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.
