Abstract

Objectives

To compare the characteristics of Klebsiella pneumoniae liver abscesses (KPLA) in diabetic patients with different levels of glycaemic control.

Methods

The institutional review board approved this retrospective study. A total of 221 patients with KPLA were included. Clinical features of KPLA were compared. We divided the 120 diabetic patients with KPLA into three subgroups based on haemoglobin A_1C (HbA_1C) concentration (good, HbA_1C ≤ 7.0 %; suboptimal, 7.0 % < HbA_1C ≤ 9.0 %; poor, HbA_1C > 9.0 %). In this study, we used a semiautomated quantitative method to assess the gas and total abscess volumes in KPLA. Statistical analysis was performed with the chi-squared test and one-way analysis of variance.

Results

The mortality rate did not significantly differ between the nondiabetic and diabetic groups. However, patients with poor glycaemic control had significantly more complications and therefore a longer hospital stay (P < 0.05). In our study, CT and quantitative analyses found that patients in the group with poor glycaemic control had a significantly higher incidence of gas formation and hepatic venous thrombophlebitis and a higher gas-to-abscess volume ratio than patients with suboptimal and good glycaemic control (P < 0.05).

Conclusions

Diabetic patients with a high HbA_1C concentration (>9.0 %) have an association with hepatic venous thrombophlebitis, gas formation and metastatic infection complications associated with KPLA.

Key Points

• Poorly controlled diabetes is associated with complications in Klebsiella pneumoniae liver abscesses.

• Hepatic venous thrombosis and gas are important signs of metastatic infection.

• Hepatic venous thrombophlebitis is associated with 72.7 % of metastatic infections.
