The aim of this study was to characterise the dynamic immune profile of paediatric burn patients for up to 18 months post‐burn.

Flow cytometry was used to measure 25 cell markers, chemokines and cytokines which reflected both pro‐inflammatory and anti‐inflammatory immune profiles. Peripheral blood mononuclear cells from 6 paediatric burn patients who had returned for repeated burn and scar treatments for > 4 timepoints within 12 months post‐burn were compared to four age‐matched healthy controls.

While overall proportions of T cells, NK cells and macrophages remained relatively constant, over time percentages of these immune cells differentiated into effector and proinflammatory cell phenotypes including Th17 and activated γδ T cells. Circulating proportions of γδ T cells increased their expression of pro‐inflammatory mediators throughout the burn recovery, with a 3 …
