An Adolescent Female With Concurrent Presentation of Autoimmune Hepatitis and Secondary Syphilis
Bibliographic record
Abstract
We describe concurrent diagnoses of autoimmune hepatitis (AIH) and secondary syphilis in a 17-year-old adolescent with jaundice, with possible syphilitic hepatitis (SH) excluded after a thorough investigation. Our patient presented with a several-day history of malaise, progressive jaundice, and vomiting. She disclosed being sexually active and requested testing for sexually transmitted infections. Her subsequent investigations demonstrated acute hepatitis with a positive antinuclear antibody and elevated IgG. She also tested positive for syphilis with a reactive rapid plasma regain and treponema pallidum particle agglutination assay. We considered 2 etiologies for her elevated liver enzymes: syphilitic hepatitis and AIH. AIH was confirmed on liver biopsy, establishing the first reported pediatric case of concurrent AIH and secondary syphilis. Syphilis is hypothesized to be an infectious trigger for AIH.

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.
