Transient Cerebral Ischemic Attack and Delirium Heralding the Vasculitic Phase of Eosinophilic Granulomatosis With Polyangiitis (Churg-Strauss Syndrome)
Bibliographic record
Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome, is a rare systemic vasculitis characterized by a prodromic history of allergic asthma and sinusitis for many years, followed by an eosinophilic phase and a vasculitic phase. Central nervous system (CNS) involvement associated with EGPA is very rare, in particular as first sign of the vasculitic phase. We describe a patient with transient cerebral ischemic attack and delirium heralding the vasculitic phase of EGPA. We report a case of EGPA (Churg-Strauss syndrome) in a 76-year-old Italian woman with acute neurologic and neuropsychiatric symptoms and history of asthma and sinusitis. She was admitted in stroke unit with acutely developing aphasia, ataxia and delirium without acute lesions on neuroimaging. When she was transferred in neurorehabilitation unit, an anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis was suspected on the basis of anamnesis, facies (saddle nose) and presence of systemic inflammation. She was finally diagnosed with EGPA because of the presence of subclinical demyelinating polyneuropathy, interstitial pulmonary disease and increased myeloperoxidase-specific ANCA (MPO-ANCA). The patient’s neurologic symptoms were, therefore, attributed to a vasculitic process, and they improved with steroid treatment. CNS involvement associated with EGPA is very rare and, in this case it represented the first sign of systemic vasculitis after many years of prodromic phase, and it should be considered in patients with acute cerebrovascular disease associated with systemic inflammation or eosinophilia and anamnestic asthma or sinusitis.

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.
