Abstract
Chronic granulomatous disease (CGD) is an inherited defect of leukocyte phagocytic function leading to recurrent infections. Autoimmune manifestations are reported in up to 6% of patients with CGD. We report a case of CGD presenting with arthritis as the first manifestation of disease. A 12-year-old Pakistani male of consanguineous parents presented with migratory arthritis and painless oral ulcerations of 6 months duration that were minimally responsive to nonsteroidal anti-inflammatory treatment. Initial assessment demonstrated elevated inflammatory markers (ESR 62), weakly positive ANA (titer 1:40), negative anti-DsDNA, and negative RF. He presented to the emergency department with fevers and arthritis. Repeat work-up suggested early Macrophage Activation Syndrome: normocytic anemia (Hgb 95 g/L), thrombocytopenia (Plt 141 × 10 9 /L), elevated LDH 1603, ferritin 1230 mcg/L, ESR 127, CRP 9.3, hypertiglycerdemia (3.2 mmoL/L) and mild transaminitis (ALT 63, AST 87), normal bone marrow (no hemophagocytosis), but mildly elevated Soluble CD 136 (1086 ng/mL) and Soluble IL-2 receptor (CD25) (1698 U/mL). He was treated with oral prednisone with symptom resolution. The arthritis relapsed after 1 month and the patient developed fever, productive cough, and pleuritic chest pain. Chest imaging revealed multiple nodular opacities and enlarged mediastinal lymph nodes. Aspergillus fumigatus complex was isolated from induced sputum prompting screening for primary immunodeficiency. Neutrophil oxidative burst function, as assessed by a dihydrorhodamine flow cytometry based assay, was low at 1.26 and 1.48 (normal range 32–300). Genetic analysis showed a previously described mutation in the NCF1 gene confirming the diagnosis of autosomal-recessive CGD. CGD can present with an exclusively rheumatologic presentation including arthritis and oral ulceration. Statement of Novelty: This case demonstrates that CGD can present with rheumatological symptoms prior to any infectious features.

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 it
