Systemic inflammation in humans may be triggered by infection, termed sepsis, or non-infective processes, termed non-infective systemic inflammatory response syndrome (SIRS). MicroRNAs regulate cellular processes including inflammation and may be detected in blood. We aimed to establish definitive proof-of-principle that circulating microRNAs are differentially affected during sepsis and non-infective SIRS. Critically ill patients with severe (n?=?21) or non-severe (n?=?8) intra-abdominal sepsis; severe (n?=?23) or non-severe (n?=?21) non-infective SIRS; or no SIRS (n?=?16) were studied. Next-generation sequencing and qRT-PCR were used to measure plasma microRNAs. Detectable blood miRNAs (n?=?116) were generally up-regulated in SIRS compared to no-SIRS patients. Levels of these 'circulating inflammation-related microRNAs' (CIR-miRNAs) were 2.64 (IQR: 2.10-3.29) and 1.52 (IQR: 1.15-1.92) fold higher for non-infective SIRS and sepsis respectively (p?
