P.031 Intravenous immunoglobulins (IVIG) therapy in chronic inflammatory demyelinating polyneuropathy (CIDP): time to maximal recovery
Bibliographic record
Abstract
Background: The response of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) to Intravenous Immunoglobulins (IVIG) treatment is well established . However, determination if patients not responding to 2 IVIG treatments or those whose condition stabilizes (ICE Trial) may benefit from additional doses remains unclear. We aim to identify time period required to reach maximal strength gains from IVIG treatment. Methods: Retrospective chart review of 14 patients with CIDP was performed. Change in Grip strength (GS), Knee extension (KE), Elbow Flexion (EF) and Dorsflexion(DF) was analyzed with a dynamometer during IVIG therapy. Averages for : percent change from baseline(Max%Δ),cumulative grams(g) of IVIG and time in weeks(w) required for maximal strength recovery was determined per function (+/−SEM).Anciliary therapy for all patients was recorded. Results: Strongest improvement was observed for DF(124+/−30%,p<0.001), followed by KE(113+/−19%,p<0.01),GS(100+/−21%,p<0.001) and EF(98+/−14%p<0.05).GS improved the fastest(19.1+/−3w) followed by DF(29.5+/−7w),KE(29.6+/−4w) and EF(31+/−6w). Cumulative IVIG dose to reach Max%Δ was highest for EF(869+/−201g) and lowest for GS(573+/−78g). Conclusions: Our study has demonstrated effectiveness of multiple treatments with IVIG to reach significant improvement in strength. Different muscle groups manifested different time-dependency ,reflecting variable amounts of IVIG required. Improvement was identified to be present on a ongoing basis ,with therapy lasting between 19.1-31 weeks,requiring between 869-573g of IVIG.

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.
