Markedly upregulated serum interleukin-12 as a novel biomarker in POEMS syndrome

Abstract

Our findings suggest that serum IL-12 is a biomarker of the disease activity in POEMS syndrome. The overproduction of IL-12, as well as VEGF, is likely to play an important role in the pathogenesis of the disorder, and could contribute to the peripheral nerve demyelination in POEMS syndrome.
