The correlation between serum HIF-1 α,VEGF,sTREM-1 and inflammatory factors and incision infection after anal fistula surgery
Objective To investigate the correlation between serum hypoxia inducible factor 1 alpha(HIF-1α),vascular endothelial growth factor(VEGF),soluble triggering receptor expressed on myeloid cells-1(sTREM-1),and inflammatory factors and incision infection after anal fistula surgery.Methods A retrospective analysis was conducted on the clinical data of 120 patients who underwent anal fistula thread hanging surgery at the First People's Hospital of Shuangliu District,Chengdu from June 2022 to April 2023.The patients were divided into an infected group(36 cases)and a non infected group(84 cases)based on their postoperative incision infection status.The differences in serum HIF-1 α,VEGF,sTREM-1 and inflammatory factors[C-reactive protein(CRP),interleukin-6(IL-6),tumor necrosis factor α(TNF-α)]between the infected and non infected groups were compared,and the correlation between CRP,IL-6,TNF-α,HIF-1 α,VEGF,sTREM-1 and postoperative infection of anal fistula was analyzed by Pearson correlation coefficient;The correlation between CRP,IL-6,TNF-α and HIF-1 α,VEGF,sTREM-1.And the efficacy of serum HIF-1 α,VEGF,sTREM-1,inflammatory factors and their individual and combined diagnosis of incision infection after anal fistula surgery was analyzed by receiver operating characteristic(ROC)curve analysis.Results The levels of serum HIF-1 α,sTREM-1,CRP,IL-6,and TNF-α in the infected group were higher than those before surgery and higher than those in the uninfected group 3 days after surgery;VEGF levels were lower than preoperative levels and lower than those in the non infected group(all P＜0.05).Pearson correlation analysis showed that HIF-1α,sTREM-1,CRP,IL-6,TNF-α were positively correlated with postoperative infection in anal fistula(r=0.456,0.494,0.455,0.510,0.363,all P＜0.05),while VEGF was negatively correlated with postoperative infection in anal fistula(r=-0.462,P＜0.05).CRP,IL-6,TNF-α were positively correlated with HIF-1 α and sTREM-1(r=0.574/0.611/0.653,0.661/0.608/0.610,all P＜0.05),while CRP,IL-6,TNF-α were negatively correlated with VEGF(r=-0.200,-0.207,-0.254,all P＜0.05).The area under the curve(AUC)of HIF-1 α,VEGF,sTREM-1,CRP,IL-6,and TNF-α for diagnosing incision infection after anal fistula surgery were 0.716,0.787,0.741,0.678,0.792,and 0.688,respectively.The AUC of the combined diagnosis of inflammatory factors and 6 data points for postoperative incision infection in anal fistula surgery were 0.836 and 0.921,respectively.Conclusions Serum levels of HIF-1 α,sTREM-1,CRP,IL-6,and TNF-α are abnormally high in patients with incision infection after anal fistula surgery,while VEGF is abnormally low in expression.HIF-1 α,VEGF,sTREM-1,and inflammatory factors can be used as effective indicators for clinical diagnosis of incision infection after anal fistula surgery,and their combined diagnostic value is better.HIF-1 α and sTREM-1 are positively correlated with inflammatory factors,while VEGF is negatively correlated with inflammatory factors.
