Abstract:
Objective:To investigate the value of serum trimethylamine N-oxide (TMAO) level in evaluating the severity and short-term clinical prognosis of patients with sepsis.Methods:A prospective case-control study was conducted. Patients in the case group were admitted to the emergency intensive care unit of Shanghai Putuo District People′s Hospital Affiliated to Tongji University from March 2018 to December 2019. According to the diagnosis criteria of sepsis 3.0 in 2016, the patients in the case group were divided into sepsis non shock group (33 cases) and septic shock group (12 cases). They were divided into survival group and death group according to 28 day outcome; Healthy volunteers were selected as control group (30 cases). The levels of C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), Acute Physiology And Chronic Health Evaluation Ⅱ (APACHE Ⅱ) and the sequential organ failure assessment (SOFA), serum TMAO were compared. The relationship between serum TMAO, sepsis severity and short-term clinical prognosis were analyzed.Results:The serum IL-6, CRP, PCT, scores of SOFA and APACHE Ⅱ in septic shock group were significantly higher than those in normal sepsis group ( P<0.01). The serum IL-6, PCT, scores of SOFA and APACHE Ⅱ in the death group of sepsis patients were significantly higher than those in the survival group ( P<0.01). The serum TMAO level of the sepsis group on 1st day was significantly higher than that of the healthy control group ( P<0.01). The serum TMAO level in the septic shock group on the 1st, 3rd and 7 th day was higher than that in the normal sepsis group, with statistically significant difference ( P<0.01). The serum TMAO level in the septic shock group and normal sepsis group on the third day were significant different with the first day ( P<0.01). The serum TMAO level in the death group on the 1st, 3rd and 7th day was higher than that in the survival group, with statistically significant difference ( P<0.05). And the serum TMAO level in the death group and survival group on the third day were significant different with the first day ( P<0.01). The serum TMAO level of sepsis patients was positively correlated with APACHE Ⅱ score ( r=0.848, P<0.01). The level of TMAO was positively correlated with serum IL-6 ( r=0.956, P<0.01). Conclusions:Serum TMAO is closely related to the severity and recent clinical prognosis of patients with sepsis, and is a risk factor for the death of patients with sepsis.
