Abstract:
BackgroundCurrent research indicated the comprehensive investigation of Annexin A3 (ANXA3) in sepsis patients remain uncertain. The aim of this research is to investigate the potential of ANXA3 as a biomarker for prediction of sepsis.MethodsWe performed a meta-analysis utilizing public datasets from Gene Expression Omnibus (GEO) and Array Express database to summarize and evaluate the expression of ANXA3 in sepsis patients. Then, we conducted a retrospective study to explore the role of plasma ANXA3 in 153 critically ill patients. Furthermore, the predictive ability of ANXA3, procalcitonin (PCT), interleukin-6 (IL-6) and Sequential Organ Failure Assessment (SOFA) score for the occurrence of sepsis were evaluated using the Area Under the Curve (AUC).ResultsTotally, the meta-analysis including 3241 sepsis and 1088 controls indicated sepsis patients were with markedly higher levels of ANXA3 mRNA expression (SMD = 2.01(1.54-2.48); P < 0.001). Meanwhile, sepsis deaths (n = 552) were with limited higher expression of ANXA3 mRNA than sepsis survivors (n = 2004) (SMD = 0.14(0.04-0.24); P < 0.01). Furthermore, our results indicated increased plasma ANXA3 on admission were significantly associated with the incidence of sepsis in critically ill patients (OR = 2.41(1.75-3.32), P < 0.001). As a predictive biomarker, plasma ANXA3 resulted in a better AUC 0.815(0.745-0.886) than PCT (0.673(0.584-0.761)) and IL-6 (0.672(0.585-0.759)) and SOFA score (0.668(0.577-0.759)). Additionally, patients with higher plasma ANXA3 had a poorer overall 28-day survival in critically ill patients (HR = 2.16(1.09-4.28); P < 0.05), but not for sepsis patients (HR = 1.63(0.65-4.06); P > 0.05).ConclusionsOur study indicated increased ANXA3 obtained a good predictive ability for sepsis. Meanwhile, plasma ANXA3 was associated with mortality of critically ill patients, but not sepsis patients. The use of ANXA3 as a biomarker in sepsis patients require further evaluation in larger studies.
