Incidence and outcome of ischemic hepatitis complicating septic shock.

ABSTRACT

AIM: The specific incidence of ischemic hepatitis in septic shock patients remains unknown. The aim of this study was to evaluate the incidence of ischemic hepatitis in septic shock and its relationship with mortality. METHODS: We retrospectively studied 181 patients with septic shock admitted to the intensive care unit (ICU). We defined ischemic hepatitis as having a value of serum aminotransferases equal to or higher than 1000 IU/L. We recorded the age, sex, comorbidity, site of infection, the Sequential Organ Failure Assessment (SOFA) score on admission to the ICU, maximum SOFA score and inadequate antibiotic therapy. RESULTS: Twenty-five (13.8%) patients developed ischemic hepatitis. In-hospital mortality was 57% (103 patients). In the ischemic hepatitis group, mortality increased up to 84.0% (21 patients) compared with 52.6% (82 patients) in patients without ischemic hepatitis (control group) (odds ratio [OR] 4.7; 95% confidence interval [CI] 1.6-14.4; P = 0.003). The development of ischemic hepatitis, age, maximum SOFA score and inadequate antibiotic therapy were independently associated with an increased risk of death. The odds of death increased by 247% in ischemic hepatitis (OR 3.47; 95% CI 1.02-11.8; P = 0.047). CONCLUSION: Ischemic hepatitis is a common complication in septic shock patients, associated with a high mortality.
