Clinical characteristics and prognosis of patients with early sepsis-related liver injury in Northeast China.

Sepsis-associated liver injury (SALI) occurs in about a third of septic patients, and it is often a poor prognostic factor. However, there are few studies on early SALI and its impact on the clinical course of sepsis. Here we explored the clinical characteristics, risk factors, and prognosis of early SALI. Two hundred and one patients with confirmed sepsis were divided into those with and without early SALI (on admission) based on liver function. The clinical characteristics and prognosis were compared between groups and associated factors identified by multivariable regression analysis. Sepsis-related liver injury was present in 18.9% of septic patients on admission. High aspartate transaminase (AST), high direct bilirubin, and low plasma thromboplastin antecedent (PTA, factor XI) were risk factors for sepsis with SALI: the area under the AST curve was 0.825, corresponding to a sensitivity of 0.67 and a specificity of 0.93 (cutoff 91.6 U/L), the area under the direct bilirubin curve was 0.86, corresponding to a sensitivity of 0.83 and a specificity of 0.71 (cutoff 8.35 μmol/L), and the area under the PTA curve was 0.678, corresponding to a sensitivity of 0.47 and a specificity of 0.93 (cutoff 54.0). Septic patients with early SALI have early-onset coagulation disorders that must be recognized to instigate early intervention and halt sepsis progression. Elevated AST, PTA, and direct bilirubin may be independent risk markers of sepsis-related liver injury, and extra clinical vigilance is required when these factors are noted in patients with sepsis.
