Principal-component analysis for sTNFR1 and five neuropeptides in serum from 21 patients with long-standing RA, and for the ESR. BN/GRP, bombesin/gastrin-releasing peptide; CGRP, calcitonin-gene-related peptide; ESR, erythrocyte sedimentation rate; NPY, neuropeptide Y; RA, rheumatoid arthritis; SP, substance P; sTNFR1, soluble tumour necrosis factor receptor 1; VIP, vasoactive intestinal peptide. |
