Sequential assessment of an antidrug antibody response in a patient with a systemic delayed-onset sulphonamide hypersensitivity syndrome reaction
Bibliographic record
Abstract
A 19-year-old man was treated with trimethoprim-sulphamethoxazole intermittently over 4 weeks. He developed a rash and fever. Despite treatment with low-dose methylprednisolone, his condition worsened. He developed a confluent erythematous macular eruption, elevated liver enzymes, lymphadenopathy, polyserositis and eosinophilia. A tentative diagnosis of sulphonamide hypersensitivity syndrome reaction (SHSR) was made and a serum sample (acute) was obtained to screen for antibodies associated with SHSR. Intravenous methylprednisolone sodium succinate (250 mg every 6 h for 48 h) was administered. The patient's condition improved, and he was discharged with oral prednisone. A convalescent serum sample was obtained 14 weeks later. By Western blotting and enzyme-linked immunosorbent assay (ELISA), antisulphamethoxazole IgG antibodies were detected in the acute serum sample, supporting the clinical diagnosis of SHSR. Contrary to expectations, antibodies were not detected in the convalescent serum sample by immunoblotting. Antisulphamethoxazole antibodies were detected by ELISA in the convalescent serum, but the titre was decreased approximately 45-fold. One possible explanation for the decrease in antibody concentration in the convalescent sample was the administration of high-dose glucocorticoids to the patient following collection of the acute serum sample.

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.
