Systemic lupus erythematosus associated with development of macrophage activation syndrome and disseminated aspergillosis
Bibliographic record
Abstract
PURPOSE: Macrophage activation syndrome (MAS) is a rare illness, especially in critically ill adults. The diagnosis of MAS is challenging, requiring the expertise of multiple specialists, and treatments for MAS can be associated with catastrophic complications. CLINICAL FEATURES: We describe the case of a 31-yr-old Vietnamese student who was diagnosed with cutaneous systemic lupus erythematosus (SLE) in November 2020 and was initiated on treatment with low-dose corticosteroids and hydroxychloroquine as an outpatient. Ten days later, she presented to hospital with decreased consciousness, fever, periorbital swelling, and hypotension necessitating intubation. Computed tomography angiography (CTA) and lumbar puncture did not show a stroke or central nervous system infection. Serology and clinical presentation were consistent with MAS. She was initially treated with 4.5 g pulse methylprednisolone and subsequently with the interleukin-1 receptor antagonist, anakinra, and maintenance corticosteroids because of persistently elevated inflammatory markers. Her intensive care unit stay was complicated by aspiration, airway obstruction due to fungal tracheobronchitis necessitating extracorporeal membrane oxygenation (ECMO), and ring-enhancing cerebral lesions, and, ultimately, massive hemoptysis resulting in death. CONCLUSIONS: Four features of this case merit discussion, including the: 1) infrequent association of SLE with MAS; 2) short interval between SLE diagnosis and critical illness; 3) manifestation of fungal tracheobronchitis with airway obstruction; and 4) lack of response to antifungal treatment while receiving ECMO.

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.
