Abstract
AIMS: Type I membranoproliferative glomerulonephritis (MPGN) is an immune-complex disease with a relatively poor prognosis. It has no established treatment in adults. Our hypothesis was that this disease would respond to B cell depletion with rituximab, an anti-CD20 monoclonal antibody. METHODS: We conducted an openlabel trial, in Canada and the United States, of rituximab in 6 adult patients with Type I MPGN (4 idiopathic, 2 with cryoglobulinemia). The rituximab dose was 1,000 mg intravenously on Day 1 and on Day 15. The patients were followed for 1 year. The primary outcome was the change in proteinuria. RESULTS: Peripheral blood B cells were suppressed, after rituximab, in all patients. The mean urinary protein excretion was 3.9 ± 2.0 g/d before treatment. Proteinuria fell in all patients, at all-time points, after rituximab administration. The difference was statistically significant (p < 0.05) at 6, 9 and 12 months, but not at 3 months. The minimum mean urinary protein excretion was 1.4 ± 1.4 g/d at 9 months. There were 2 complete and 3 partial remissions among the 6 patients. The creatinine clearance did not change significantly over the course of the study. There were no adverse effects. CONCLUSIONS: Rituximab reduced proteinuria among patients with Type I MPGN. This trial suggests that B cells may play a role in this disease and that additional study of B-cell suppression is warranted.

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 it
