IntroductionCytokines compose a network and play crucial roles in the pathogenesis and prognosis of sepsis. Adipose tissue is an important immune endocrine organ that releases adipocytokines. This study aimed to evaluate adipocytokines in sepsis from a network perspective.Materials And MethodsThis retrospective study of 37 patients with sepsis and 12 healthy controls was conducted from February 2014 to July 2015. Blood samples were collected from patients on days 1 (within 24 h of diagnosis), 2, 4, 6, 8, 11, and 15 and from healthy controls. Adipocytokines (adiponectin, leptin, resistin, chemerin, visfatin, vaspin, CXCL-12/SDF-1, angiotensinogen), inflammatory cytokines (IL-1β, IL-4, IL-6, IL-8, IL-10, IL-12/IL-23p40, TNF-α, monocyte chemotactic protein [MCP-1]), and plasminogen activator inhibitor-1 were measured. Acute Physiology and Chronic Health Evaluation II score was evaluated on day 1, and Sequential Organ Failure Assessment (SOFA) score and Japanese Association for Acute Medicine (JAAM) and International Society of Thrombosis and Hemostasis overt disseminated intravascular coagulation (DIC) scores were assessed at the times of blood sampling.ResultsHierarchical clustering analysis showed the cluster formed by resistin, IL-6, IL-8, MCP-1, and IL-10 on days 1, 2, and 4 represented the cytokine network throughout the acute phase of sepsis. Each cytokine in this network was significantly associated with SOFA and JAAM DIC scores over the acute phase. A Cox proportional hazards model focusing on the acute phase showed a significant relation of these five cytokines with patient prognosis.ConclusionsAdipocytokines and an inflammatory cytokine profile assessed over time in sepsis patients showed that resistin was involved in an inflammatory cytokine network including IL-6, IL-8, IL-10, and MCP-1 in the acute phase of sepsis, and this network was associated with severity and prognosis of sepsis.Copyright © 2021 by the Shock Society.
