[Assessment values of procalcitonin, lactic acid, and disease severity scores in patients with sepsis].

OBJECTIVE: To investigate the assessment values of procalcitonin (PCT), lactic acid (LAC), sequential organ failure assessment (SOFA) score and acute physiology and chronic health evaluation II (APACHE II) score in patients with sepsis. METHODS: 140 patients with suspicious bacterial infection admitted to emergency department of Beijing Chaoyang Hospital of the Capital Medical University from August 2017 to June 2018 were enrolled. They were divided into three groups according to diagnostic criteria of Sepsis-3: non-sepsis group (n = 58), sepsis group (n = 66) and septic shock group (n = 16). The PCT, LAC, SOFA score, APACHE II score, 28-day prognosis, and positive detection rate of PCT and LAC were compared among three groups. Independent predictors of 28-day mortality were analyzed by Logistic regression; predictive values of PCT, LAC, SOFA score and APACHE II score for 28-day mortality in sepsis patients were analyzed by receiver operating characteristic (ROC) curve. RESULTS: = 2.45, both P < 0.01), and the performance of SOFA score was similar to PCT. CONCLUSIONS: PCT, LAC, SOFA score and APACHE II score were reliable indexes to evaluate disease severity for patients diagnosed with infection. The assessment values of APACHE II score and LAC in 28-day mortality were superior to SOFA score and PCT.
