Trimethoprim-sulfamethoxazole and antineutrophil cytoplasmic antibodies-associated vasculitis
Bibliographic record
Abstract
PURPOSE OF REVIEW: In antineutrophil cytoplasmic antibodies-associated vasculitis (AAV), the treatment of choice is either Rituximab or cyclophosphamide in combination with steroids. In less extended forms of AAV, however, less toxic regimens are being used.In the current review, we will focus on the role of one of these less toxic regimens, that is trimethoprim-sulfamethoxazole monotherapy as induction treatment or as maintenance therapy in AAV. RECENT FINDINGS: A substantial portion of patients with active granulomatosis with polyangiitis (GPA) limited to the upper airways can be initially controlled with trimethoprim-sulfamethoxazole (2 × 960 mg/day) monotherapy. In patients with initially a complete response, long-term control of the disease seems possible. In addition, trimethoprim-sulfamethoxazole (2 × 960 mg/day) maintenance therapy is an option for patients with GPA that have been proven to be frequent relapsers. The mechanism by which trimethoprim-sulfamethoxazole works in GPA is at present unknown. Suppression of Staphylococcus aureus carriage and/or anti-inflammatory mechanisms has been postulated. SUMMARY: Trimethoprim-sulfamethoxazole may be considered as a safe initial treatment in GPA patients with disease localized to the ear, nose, and throat region. Furthermore, trimethoprim-sulfamethoxazole in a dose of 2 × 960 mg/day may be used to prevent relapses in GPA.

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.
