Inherited Immunodeficiency: A New Association With Early-Onset Childhood Panniculitis
Bibliographic record
Abstract
We report on 4 children who presented with aseptic panniculitis associated with inherited immunodeficiency. Three patients had a B-cell immunodeficiency resulting from mutations in the TRNT1 and NF-κb2 genes (no mutation was found in the third patient), and 1 had a T-cell deficiency (mutation in the LCK gene). Panniculitis occurred before the age of 2 years in the 4 patients and preceded the onset of recurrent infections because of immunodeficiency in 2. It presented either as nodules, which resolved spontaneously within 1 to 2 weeks (3 patients), or chronic ulcerative lesions (1 patient) associated with unexplained fever and elevated acute phase reactants, without evidence of infection or high-titer autoantibodies. Febrile nodules relapsed in 2 patients, and recurrent attacks of unexplained fever (without relapse of panniculitis) occurred in the third. Skin biopsy revealed predominantly lympho-histiocytic or septal neutrophilic panniculitis in 1 and 3 patients, respectively. Panniculitis was associated with dermal involvement in the 4 patients. Patients with B-cell deficiency received monthly intravenous immunoglobulin replacement. Two patients who underwent bone marrow transplant died of bone marrow transplant-related complications. The 2 remaining patients had persistent, mild autoinflammatory disease, which did not require specific treatment. In these cases, the need for careful immunologic evaluation of patients who present with unexplained panniculitis, especially early-onset panniculitis before the age of 2 years, is highlighted.

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.
