Abstract 17623: A Case of Biopsy-proven Immunoglobulin G4-Related Disease Associated With Multiple Giant Coronary Artery Aneurysms, Peripheral Arterial Aneurysms, End Stage Renal Disease, and Heart Failure
Bibliographic record
Abstract
A 54-year-old man with remote large cell non-Hodgkin’s lymphoma in remission following R-CHOP and severe atopic dermatitis was transferred from another hospital with a non-ST elevation myocardial infarction. Over the preceding year, the patient had suffered recurrent admissions for acutely decompensated heart failure with a newly depressed left ventricular ejection fraction (LVEF) of 20% by echocardiography and rapidly progressive end-stage renal disease of unclear etiology requiring the initiation of hemodialysis. Prior workup had demonstrated an infrarenal abdominal aortic aneurysm and bilateral common iliac artery aneurysms with subsequent computed tomography (CT) additionally demonstrating a superior mesenteric artery aneurysm. The patient was taken for immediate coronary arteriography, which demonstrated giant aneurysms in the left main and right coronary arteries, as well as multivessel severe stenoses. CT coronary angiogram demonstrated significant circumferential wall thickening throughout the coronary vasculature. Given concern for IgG4-related disease (IgG4-RD), a renal biopsy was pursued that confirmed the diagnosis. 18F-fluorodeoxyglucose positron emission tomography-CT identified only mild aortic inflammation. The patient was treated with high-dose steroids and rituximab. The serological inflammatory markers improved, and he underwent coronary artery bypass grafting. Pericardial, aortic adventitial, left internal mammary artery, and saphenous vein biopsies showed cardiovascular involvement of IgG4-RD. The patient has been maintained on rituximab with normalization of his LVEF and no recurrence of chest pain over the past eighteen months. IgG4-RD is a fibroinflammatory systemic disease newly described in 2003 and only recently found to involve the cardiovascular system with several reports of peripheral aneurysmal disease. To our knowledge, the current case represents the first report of a patient successfully treated for biopsy-proven IgG4-RD associated with coronary artery disease and left ventricular systolic dysfunction. IgG4-RD may represent a novel mechanism underlying some forms of peripheral and coronary arterial disease and may offer new insights into vascular biology.

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.
