P.063 Refractory pediatric CIDP converting to full recovery with rituximab
Bibliographic record
Abstract
Background: Chronic inflammatory demyelinating polyradiculoneuropathies (CIDP) is a rare, acquired polyneuropathy, especially in children, affecting the peripheral nervous system. It most commonly presents in a symmetric, proximal and distal, sensorimotor fashion. Immunosuppression and immunomanipulation are treatment modalities. We present a case of a 14 year old male with severe progressive CIDP who became refractory to steroid and IVIg but responded to Rituximab. Methods: Case presentation: A 14-year-old male with a history of asymmetric quadriparesis was diagnosed with CIDP. He had an initial partial response to IVIG and prednisone but then rapidly became refractory to even weekly IVIG and prednisone. Rituximab was therefore started. Results: Within 12 weeks his strength improved from quadriplegia to walker-assisted gait. By 22 weeks he achieved independent ambulation. His JAMAR hand grip increased from 0 to 28 kg. His worst recordable median conduction velocity (CV) improved from a nadir (MRC 0/5) of 14% of normal to 52% at full recovery (MRC 5/5). Conclusions: This case highlights several important clinical points. Dramatic improvement is possible in cases of quadriplegic CIDP. Strength recovery is not linearly related to CV recovery. There appears to be a role for polytherapy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
