Polyarteritis nodosa - Challenges and options in management
Bibliographic record
Abstract
Abstract Polyarteritis nodosa (PAN) was one of the first systemic necrotizing vasculitides to be described, in the late 19th century. Hepatitis B virus (HBV) was the major cause of the observed PAN cases between 1970 and the early 2000s. However, in the revised 2012 Chapel Hill Consensus Conference nomenclature, HBV-related PAN is now included with vasculitides associated with probable etiologies (and named HBV-associated vasculitis). PAN should thus now refer exclusively to primary cases, without an identified or probable cause. Besides systemic forms of the primary and “classical” PAN, which have become more rare over the past decade, isolated and/or single organs can be affected, including the skin. In this article, we review the main clinical, biological, and radiological characteristics of “classical” primary PAN and its different forms, their treatment options, and outcomes. We also discuss other possible etiologies (other than HBV) of PAN-like medium-sized vessel vasculitis and newly described PAN-like vasculopathies, such as recessive loss-of-function mutations in adenosine deaminase 2, as well as the treatment options for isolated or refractory cases and the current place of biologic agents for the treatment of PAN.

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.
