Circulating S100A8 and S100A9 protein levels in plasma of patients with acquired aplastic anemia and myelodysplastic syndromes.

ABSTRACT: The alarmin family members S100A8 and S100A9 are acute phase inflammation proteins, but they also have been proposed as biomarkers in many malignant and non-malignant diseases. In this study, circulating S100A8 and S100A9 homodimers and S100A8/A9 heterodimers in plasma were systematically investigated by ELISA in aplastic anemia (AA) and myelodysplastic syndromes (MDS). Plasma was obtained from 58 severe AA (SAA) and 30 MDS patients, and from 47 age- and sex-matched healthy donors. In 40 out of the 58 AA subjects, S100A protein levels were measured before and 6 months after immunosuppressive therapy (IST). No differences were observed in AA patients at diagnosis compared to healthy controls for circulating S100A homodimers and heterodimers. After therapy, SAA-responders showed significantl
