Abstract:
Objective To investigate the clinical characteristics and risk factors of bacterial liver abscess (BLA) complicated with septicemia.Methods Fifty two BLA patients complicated with septicemia admitted in our hospital from January 2011 to December 2015 were retrospectively reviewed;and 52 cases of BLA without septicemia admitted at the same period were randomly selected as control group.The clinical manifestations, laboratory and radiographic findings, clinical outcome of these patients were analyzed.Logistic regression analysis was used to study the clinical features and risk factors of BLA complicated with septicemia.Results Compared to the control group, the BLA with septicemia group had higher prevalence rates in diabetes mellitus, malignant tumors, jaundice, albumin <35 g/L, BUN≥8.2 mmol/L, hyperglycemia, multiple abscesses and abscesses size ≥10 cm(P<0.05 or <0.01).The blood culture showed that K.pneumoniae(63.3%) was the most commonly isolated pathogen, followed by E.coli(16.7%).Univariate analysis revealed that diabetes mellitus(OR=2.200,95%CI 1.042-4.646), malignant tumors (OR=3.667,95%CI 1.023-13.143), albumin <35 g/ L(OR=2.800,95%CI 1.009-7.774), BUN≥8.2 mmol/L(OR=3.167,95%CI 1.265-7.929), hyperglycemia(OR=3.400,95%CI 1.254-9.216), multiple abscesses(OR=2.667,95%CI 1.043-6.815), abscesses size≥10 cm (OR=5.000,95%CI 1.096-22.820) were positively associated with bacterial liver abscess complicated with septicemia.Multivariate Logistic regression showed that abscesses size≥10 cm (OR=14.016,95%CI 1.354-145.070) was an independent risk factor for complication of with septicemia.Conclusion septicemia is a common complication for bacterial liver abscess, clinically effective measures shauld be taken to prevent and control risk factors associated with septicemia.
