Predictive Value of CRP, PCT and ESR on Piperacillin-Tazobactam in Treating Chronic Obstructive Pulmonary Disease with Pneumonia by BinHao Xu, Li Han

Background: The goal of this paper was to investigate the predictive value on the efficacy of C-reactive protein (CRP), procalcitonin (PCT), and erythrocyte sedimentation rate (ESR) on piperacillin-tazobactam in the treatment of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) complicated with pneumonia.
Methods: From January 2018 to May 2021, 52 AECOPD patients (AECOPD group) and 91 AECOPD patients with pneumonia (pneumonia group) were enrolled, and the levels of CRP, PCT, and ESR were compared. The pneumonia group was divided into a mild group and a severe group, and the correlation between the levels of CRP, PCT, and ESR and the severity of pneumonia was analyzed. The patients in the pneumonia group were treated with piperacillin and tazobactam, and the clinical efficacy of CRP, PCT, and ESR levels was analyzed.
Results: The pneumonia group, particularly the severe subtype, had higher CRP, PCT, and ESR than the AECOPD group. CRP, PCT, and ESR levels were related to the severity of pneumonia and were negatively associated with the efficacy of piperacillin and tazobactam. The AUC of the combined detection of CRP, PCT, and ESR levels was greater than 0.8 to evaluate the efficacy of piperacillin-tazobactam treatment. CRP ≥ 67.19 mg/L, PCT ≥ 1.73 ng/mL, and ESR ≥ 29.42 mm/hour were the related factors affecting the efficacy of piperacillin-tazobactam.
Conclusions: CRP, PCT, and ESR levels are related to the severity of AECOPD complicated with pneumonia, and have value in evaluating the efficacy of piperacillin-tazobactam.
