Clinical features of ischemic hepatitis caused by shock with four different types: a retrospective study of 328 cases.


PMID 26629201

Abstract

The aim of the study was to investigate the clinical features of ischemic hepatitis due to shock with four different types (allergic shock, hypovolemic shock, septic shock, and cardiogenic shock). A total of 328 patients (200 males, 128 females, mean age, 65.84 ± 15.21 years old, range, 15-94 years) diagnosed with shock in Tongji Hospital were retrospectively investigated from Jun 2008 to Feb 2010. The parameters of liver function test, including alanine aminotransferanse (ALT), aspartate aminotransferanse (AST), lactate dehydrogenase (LDH), total bilirubin (TB), alkaline phosphatase (ALP) and γ-glutamyltransferase (γ-GT), were recorded and analyzed. Besides, the serum levels of C-reactive protein (CRP) and brain natriuretic peptide (BNP) were also measured and relevant correlation analysis was conducted. Among all the cases, 242 (73.8%) patients developed ischemic hepatitis. The mortality of shock patients combined with ischemic hepatitis was significantly higher than the total mortality (26.0% vs 23.8%, P < 0.05). The incidence of hepatic damage was highest in the septic shock (87.5%), while the lowest in thehypovolemic shock (49.4%). The sensitivity of ALT elevation was higher than that of AST. In addition, CRP was positively correlated with the levels of liver function parameters in the septic shock and BNP was positively correlated with that in the cardiogenic shock. Ischemic hepatitis is a common complication of shock, increasing the mortality of shock patients. The septic shock is the most common cause of hepatic damage in shock patients. CRP may be a useful predictor for septic shock, while BNP may be a useful predictor for cardiogenic shock.
