IgG4-related aortitis/periaortitis and periarteritis: a distinct spectrum of IgG4-related disease

Abstract

IgG4-RD with PAO/PA was distinct from non-PAO/PA in demographic features, organ involvement distribution, inflammatory markers, and serum IgG4 and IgE. The most common affected vessel was the abdominal aorta, and most patients responded well with treatment.
