Abstract:
Objective To explore the clinical characteristics and features of noninfectious fever in elderly patients with aortic dilation disease.Methods A total of 599 elderly patients diagnosed with aortic dilation disease(including 274 cases of acute disease and 325 cases of chronic disease)in the Affiliated Wuxi People's Hospital of Nanjing Medical University from January 2021 to June 2024 were recruited.According to their age,the patients with acute disease were divided into aged group 1(105 cases)and non-age group 1(169 cases),and those with chronic disease were into aged group 2(231 cases)and non-age group 2(94 cases).For the 520 patients(246 cases of acute disease and 274 cases of chronic disease)subjected for endovascular repair surgery,they were assigned into aged group 3(90 cases)and non-aged group 3(156 cases)for those with acute dis-ease,and aged group 4(206 cases)and non-aged group 4(68 cases)for those with chronic disease.For the 230 patients experiencing postoperative non-infectious fever,they were divided into acute-febrile(50 cases),acute-afebrile(20 cases),chronic-febrile(106 cases)and chronic-afebrile(54 cases)groups.Their general data was compared among the groups.Multivariate logistic regression analysis was conducted to identify the risk factors for postoperative noninfectious fever.ROC curve was plotted to analyze the predictive performance of our model for postoperative noninfec-tious fever.Results The surgical rate of endovascular repair surgery was 86.81％(520/599).The aged patients had significantly lower incidences of postoperative fever and non-infectious fever than the non-aged patients(P＜0.05,P＜0.01).There were no statistical differences in the ratio of using first and second generation cephalosporins or clindamycin and the duration of postopera-tive medication between the febrile group and afebrile group(P＞0.05).Multivariate logistic re-gression analysis showed that for acute disease,implantation of polytetrafluoroethylene stents(OR=7.931,95％CI:1.945-32.337,P=0.004)was a risk factor,while administration of statins(OR=0.160,95％CI:0.032-0.807,P=0.026)was a protective factor for non-infectious fever.ROC curve analysis indicated that showed our model based on above results of multivariate logis-tic regression analysis had an AUC value of 0.836,a sensitivity of 60.0％and a specificity of 95.0％.For chronic disease,implantation of polytetrafluoroethylene stents(OR=2.558,95％CI:1.250-5.235,P=0.010)and preoperative increased temperature(OR=4.615,95％CI:1.502-14.181,P=0.008)were risk factors for non-infectious fever.Based on these results,the construc-ted model obtained an AUC value of 0.714 in ROC curve analysis.Conclusion For elderly patients undergoing aortic repair surgery,it is unnecessary to upgrade the variety of antibiotics or extend the course of treatment due to advanced age.Individualized analysis of possible infections should be conducted to promote the rational use of antibiotics.
