Recalcitrant steroid-resistant EGPA with multisystem involvement
Bibliographic record
Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA) is a multisystem disorder classically characterized by sequential histopathologic and clinical disease phases. An eosinophilic tissue infiltration phase typically precedes the development of a systemic small-vessel vasculitic phase. The contribution of these two pathogenic mechanisms to disease course and the boundaries between them are often blurred. We report the case of a 49-year-old man with established p-ANCA positive EGPA presenting acutely with central and peripheral nervous system dysfunction, diffuse alveolar hemorrhage, biopsy-proven myositis, and myocarditis resistant to steroids. The patient’s clinical course was marked by unremitting abdominal pain associated with significant weight loss. Although eosinophilic infiltrates were not observed on gastrointestinal mucosal biopsy, samples stained heavily for eosinophil peroxidase, indicating prior degranulation of eosinophils. Complete remission of eosinophil-mediated tissue infiltration and vasculitic phases was achieved only after the addition of intravenous cyclophosphamide to corticosteroid therapy. This case report demonstrates both: a) the importance of recognizing eosinophilic degranulation in addition to intact eosinophils in tissue and b) a unique presentation of a rare disease, underscoring the multifaceted and heterogeneous nature of EGPA and its overlapping disease phases.

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.
