Abstract:
Objective To investigate the prognostic value of procalcitonin (PCT) and C-reactive protein (CRP) combined with sequential organ failure assessment (SOFA) score in elderly patients with sepsis induced by pulmonary infection. Methods A retrospective study was conducted. The elderly patients aged over 60 years old with sepsis induced by pulmonary infection admitted to Guangdong Provincial Hospital of Chinese Medicine from October 2015 to December 2018 were enrolled. The PCT, CRP and SOFA scores of patients within 24 hours after admission and 28-day prognosis were recorded. The patients were divided into groups according to the severity of the disease and 28-day prognosis. The differences in above parameters among all the groups were compared. Receiver operator characteristic (ROC) curve was drawn to analyze the prognostic value of the above indicators in elderly patients with sepsis induced by pulmonary infection alone or in combination. Results A total of 265 patients were enrolled in the study. According to the severity of the disease, the patients were divided into sepsis group (n = 194) and septic shock group (n = 71). According to the 28-day prognosis, the patients were divided into survival group (n = 186) and non-survival group (n = 79). Compared with the sepsis group, the PCT, CRP and SOFA scores of patients in the septic shock group were significantly increased [PCT (μg/L): 6.16 (1.94, 19.60) vs. 1.56 (0.34, 7.32), CRP (mg/L): 128.90 (54.93, 198.70) vs. 91.45 (30.15, 175.30), SOFA score: 9.0 (7.0, 12.0) vs. 4.0 (3.0, 5.0)] with significant differences (all P < 0.05). Compared with the survival group, the PCT, CRP and SOFA scores of sepsis patients in the non-survival group were significantly increased [PCT (μg/L): 4.80 (1.06, 19.60) vs. 1.82 (0.34, 7.24), CRP (mg/L): 135.20 (58.10, 225.50) vs. 91.45 (31.50, 172.53), SOFA score: 7.0 (4.0, 11.0) vs. 4.0 (3.0, 6.0)] with significant differences (all P < 0.01). ROC curve analysis showed that the area under the ROC curve (AUC) of PCT, CRP, SOFA score and CRP+PCT+SOFA score was 0.641, 0.607, 0.697, and 0.712, indicating that above parameters had certain predictive value for 28-day prognosis of elderly patients with sepsis induced by pulmonary infection, and the combined predictive value of them was the greatest with the sensitivity of 55.1% and the specificity of 80.1%. Conclusion PCT, CRP and SOFA score are commonly used to evaluate the prognosis of the elderly patients with sepsis induced by pulmonary infection, and the combination of them has higher evaluation value.
