To compare the characteristics of Klebsiella pneumoniae liver abscesses (KPLA) in diabetic patients with different levels of glycaemic control.
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 A1C (HbA1C) concentration (good, HbA1C ≤ 7.0 %; suboptimal, 7.0 % < HbA1C ≤ 9.0 %; poor, HbA1C > 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.
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).
Diabetic patients with a high HbA1C concentration (>9.0 %) have an association with hepatic venous thrombophlebitis, gas formation and metastatic infection complications associated with KPLA.
• 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.
