Effect of a Single-Cycle Alternative Dosing Regimen for Rituximab for Recalcitrant Pemphigus
Bibliographic record
Abstract
BACKGROUND: There is increasing evidence that a single cycle of rituximab (375 mg per square meter [corrected] of body surface area once weekly for 4 weeks) is efficacious in patients with severe pemphigus. The approved protocol in rheumatoid arthritis is 1 g on days 1 and 15. We report herein on the efficacy and safety of this latter protocol for rituximab in 9 patients with pemphigus. OBSERVATIONS: Nine patients with recalcitrant pemphigus were treated with prednisone, immunosuppressive agents, and/or intravenous immunoglobulin. Rituximab, 1 g, was infused on days 1 and 15. Each patient was observed for a minimum of 6 months. Reepithelialization of at least 50% of the affected areas occurred in all patients within 16 weeks. Three of 6 patients (50%) discontinued intravenous immunoglobulin therapy. A significant decrease in the pemphigus severity score and the mean dosage of prednisone was observed at 3 and 6 months. Relapses were observed in 4 patients between 5 and 13 months after rituximab treatment; these patients completed a second cycle of rituximab. There were no serious adverse effects observed during the follow-up period. CONCLUSIONS: A single cycle of rituximab, 1 g on days 1 and 15, is an effective treatment for pemphigus. Further studies are needed to determine the efficacy and safety of repeated treatment courses in patients who experience recurrences.

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.
