Report of the <scp>ASFA</scp> Apheresis Registry Study on Focal Segmental Glomerulosclerosis
Bibliographic record
Abstract
ABSTRACT Focal segmental glomerulosclerosis (FSGS) is one of the causes of end‐stage kidney disease. The etiology is not fully understood, and standardized treatments are not established. We created a registry on apheresis for post‐transplant FSGS through the Renal Subcommittee in the Research Committee in the American Society for Apheresis (ASFA), and here is our first report. Members of the renal subcommittee from seven centers in the United States contributed data collection on demographic, clinical course, and overall outcomes of patients with post‐transplant recurrence of FSGS treated with therapeutic plasma exchange (TPE) between 2015 and 2020. The TPE data, including frequency and replacement fluid for TPE, are also investigated. The median age at diagnosis of FSGS and first transplantation among 26 patients was 12.7 and 21 years, respectively. The FSGS recurred at a median of 1 day after transplantation, and TPE was performed daily or every other day in the first month and continued at some frequency beyond a year in some cases. Most procedures used albumin as a replacement fluid and citrate anticoagulation, with 1–1.5 plasma volumes exchange. Twelve patients had complete/partial remission by 6 months. The median urine protein/creatinine ratio improved from 4.47 to 1.4 mg/mg within 3 months, and eGFR improved from 26 to 78 mL/min/1.73 m 2 in a year after TPE started. The study revealed some uniformity in the prescription of TPE, primarily using albumin as replacement fluid and performing 1–1.5 plasma volume exchanges. Observed complication rates were minimal. TPE can be one of the treatments to consider in this condition.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
