Pulmonary actinomycosis complicating infliximab therapy for Crohn disease
Bibliographic record
Abstract
The use of anti-tumour necrosis factor (TNF) agents has expanded significantly over the past few years, particularly for rheumatological diseases and Crohn disease. A number of associated opportunistic infections have been observed as a result of suppression of T-cell-mediated immunity, the most frequent being tuberculosis. This report describes a case of pulmonary actinomycosis in a 52-year-old patient receiving regular infusions of infliximab, an anti-TNF agent, for Crohn disease. He presented with a 12-day history of fever, night sweats and a non-productive cough on a background of a 9-year history of Crohn terminal ileitis. There was radiological evidence of a left upper lobe non-cavitatory pneumonia and bronchoscopic lavage fluid eventually grew Actinomyces graevenitzii. The patient was hospitalised and improved with antibiotic therapy. Within 4 weeks there was almost complete radiological resolution and infliximab was restarted after 4 months without further complication.

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.
