Abstract:
Objective To analyze the levels of serum heparin-binding protein(HBP),serum amyloid A(SAA)and C-reactive protein(CRP)in patients with chronic obstructive pulmonary disease(COPD)compli-cated with pulmonary infection,and to analyze the application effect of the three in prognosis evaluation,in or-der to provide an effective and feasible prognosis evaluation tool for clinical practice.Methods A total of 117 COPD patients complicated with pulmonary infection admitted to the hospital from January 2021 to December 2023 were selected as the observation group,and 117 COPD patients without pulmonary infection in the hospi-tal during the same period were selected as the control group.HBP,SAA and CRP levels were compared in two groups.According to the 28-day survival of the patients in the observation group,the patients were divid-ed into death group and survival group,and the related factors affecting the death of COPD patients complicat-ed with pulmonary infection were analyzed.The receiver operating characteristic(ROC)curve was used to e-valuate the efficacy of single and combined prediction of HBP,SAA,CRP for short-term prognosis in COPD patients complicated with pulmonary infection.Results The levels of HBP,SAA,and CRP in the observation group were higher than those in the control group(P<0.05).Among 117 COPD patients complicated with pulmonary infection,28 cases(23.93%)died after 28 days,and 89 cases(76.07%)survived.The age in the death group was older than that in the survival group(P<0.05),and the proportions of patients with invasive procedures,COPD duration≥10 years,and clinical pulmonary infection score(CPIS)of moderate to severe were higher than those in the survival group(P<0.05),and the levels of serum HBP,SAA,and CRP were higher than those in the survival group(P<0.05).Age,invasive procedures,COPD duration,CPIS,HBP,SAA,and CRP were independent risk factors for death in COPD patients complicated with pulmonary infec-tion(P<0.001).The area under the curve of combined prediction of HBP,SAA and CRP for short-term prognosis in COPD patients complicated with pulmonary infection was greater than that of single detection of the three(P<0.05).Conclusion The levels of serum HBP,SAA,and CRP in COPD patients complicated with pulmonary infection are closely related to the risk of death in prognosis.Analyzing the levels of these three factors could provide strong support for individualized clinical treatment of COPD patients complicated with pulmonary infection.
