Transfusion of blood components has been associated with poor patient outcomes and, an overall increase in morbidity and mortality. Differences in the blood components arising from donor health, age and immune status may impact on outcomes of transfusion and transfusion-related immune modulation in recipients. The aim of this study was to investigate differences in inflammatory profile in donors and association with parameters including age, gender and deficiency status of pattern recognition molecule mannose-binding lectin (MBL). MBL level was determined by ELISA. Serum levels of interleukin (IL)-1α, IL-1β, IL-6, IL-8, IL-10, IL-12, tumour necrosis factor (TNF)-α, macrophage inflammatory protein (MIP)-1α, monocyte chemoattractant protein (MCP)-1, interferon (IFN)-α, and IFN-γ were examined by cytometric bead array (CBA). C-reactive protein (CRP) and rheumatoid factor (RF) were examined by immunoturbidimetry. This study demonstrated age was a parameter associated with the immune profile of blood donors, with significant increases in MCP-1 (p < 0.05) and RF (p < 0.05) and decreases in IL-1α evident in the older donors (61–76 years). Significant gender-associated differences in MCP-1, IL-12 and CRP plasma levels in the blood donor cohort were also reported. There was no significant difference in the level of any inflammatory markers studied according to MBL status. This study demonstrated that age and gender are associated with inflammatory profile in donors. These differences may be a factor impacting on outcomes of transfusion.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
