Treatment of Thrombotic Thrombocytopenic Purpura Using Solvent Detergent Treated Plasma.
Bibliographic record
Abstract
Abstract Background: Patients with Thrombotic Thrombocytopenic Purpura require immediate therapy with large volumes of plasma. They have been reported to respond well to plasma exchange (PE) with FFP (78%)1 and CSP (95%)2. We initiated a randomized prospective trial with CSP and solvent detergent treated plasma (SDP) intended to show non inferiority. Methods: Patients were randomized to receive either of the exchange fluids at 1.5 PV x 3 days then 1 PV x 4–6 days. Laboratory values were followed with ADAMTS-13 levels measured according to Furlan3. The primary end point was survival at 6 months. Results: A total of 62 of the required 280 patients entered the study then the supply of SDP was discontinued. 3/35 patients receiving CSP and 1/27 on SDP died before 1 month. These values are not significant but the study is underpowered so statistical analysis is not possible. FVIII and vWF levels were elevated in all patients at entry. 34/50 patients tested also had antibodies to CD36. 9 patients had no ADAMTS-3 at entry, 19 had between 5–50%, 9 patients had 50–100% and 15/62 patients tested had normal levels. Inhibitors were present at between 5–50% levels in 22/50 patients tested whereas 9 patients had complete inhibition of ADAMTS-13 and 18 had normal enzyme activity. Conclusions: Patients with TTP appear to respond well to SDP thereby offering a relatively safer therapeutic option for PE. An insufficient number of patients were entered to achieve statistical significance. Both the ADAMTS-13 and the inhibitor levels show great variation and are not prognostic.

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.
