Effectiveness of factor VIII infusions in haemophilia A patients with high responding inhibitors
Bibliographic record
Abstract
We report here the efficacy of factor VIII (FVIII) infusions in two haemophiliacs with inhibitors using clot waveform analysis on the MDA II system, which was possible to detect very low levels of FVIII activity < 1.0 U dL(-1). In the presence of type 1 inhibitors at the level of 6.2 (patient 1) and 14.4 (patient 2) Bethesda Units mL(-1), 3.2 and 6.5 U dL(-1) of FVIII:C remained 30 min after the infusion of FVIII (100 U kg(-1)), respectively. Moreover, 0.9 U dL(-1) of FVIII:C remained 24 h after infusion in patient 2. In both cases, these changes were reflected by qualitative improvement in the aPTT clot waveform and quantitative changes in the minimum value of the second derivative of the aPTT waveform (Min2) that reflects clot acceleration. These results suggest that FVIII infusion may be continued with clinical benefit in some haemophiliacs with high responding inhibitors. Furthermore, the haemostatic response may be monitored accurately and efficiently by clot waveform analysis.

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.
