Serum Neuropeptide Y Levels Are Associated with TNF‐ <i>α</i> Levels and Disease Activity in Rheumatoid Arthritis

Abstract

Higher NPY levels are an independent marker of disease activity in RA. This study encourages the quantification of NPY levels as a surrogate marker for RA-active. Future studies evaluating the role of NPY levels interacting with other proinflammatory cytokines are required.
