Liver Abscess Metastatic Syndrome Caused by Hypermucoviscous <i>Klebsiella</i> Pneumoniae in a Canadian Patient of Vietnamese Origin
Bibliographic record
Abstract
Klebsiella pneumoniae liver abscess syndrome (KLAS) is an emerging infection caused by hypermucoviscous strains (K1, rmpA, mgA) with a particular virulence at risk of metastatic dissemination. We describe a case of metastatic KLAS in a Canadian immunocompetent patient of Vietnamese origin who presented with fever and abnormal liver function tests. Imaging studies revealed unique liver and pulmonary abscesses. Blood and liver abscess cultures showed colonies of K.pneumoniae with hypermucoviscous phenotype, a K1 serotype and the presence of a rmpA gene confirming biomolecular features of the invasive syndrome. Mostly reported in patients of Asian origin, KLAS has been reported in Canada since 2007. Prompt identification and treatment prevents severe complications such as endophthalmitis, meningitis, lung abscess and spondylodiscitis.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
