A cross-sectional study included a multivariate analysis of 30 serum inflammatory markers in patients with sarcopenia and frailty, and observed a specific pattern of inflammatory markers, with higher levels of CRP, and lower levels of IL-8, myeloperoxidase (MPO), monocyte chemoattractant protein 1 (MCP1), and platelet-derived growth factor BB (PDGF-BB). The gene discussed is CXCL8; the disease is sarcopenia.
