Objective To analyze the clinic and imaging features of Klebsiella pneumoniae liver abscess in diabetes mellitus patients with different levels of HbA1c.Methods One hundred and forty-six diabetes patients with KPLA were divided on the basis of their levels of HbA1c into three groups:complete glycemic controlled (HbA1c ≤ 7％);good glycemic controlled (7％ ＜HbA1c≤9 ％) ≤ bad glycemic controlled (HbA1c＞ 9 ％).Compared the patients' characteristics,clinic features,imaging features and complications among each group.Results Compared with patients in groups of complete and good glycemic controlled,patients in group of bad glycemic controlled tend to have younger age at onset[(with an average age of (59.1 ± 13.8)years],longer hospital stay[(with an average stay of (23.1 ± 7.6) day] and more experience complications such as:hyperlipoidemia(49 cases,77.8％),chronic renal failure(12 cases,19.2 ％),life-threatening clinical crisis,and higher infection rate.Patients in bad glycemic controlled also had high risk of biliary pneumatosis(18 cases,28.6 ％),hepatic venous thrombosis (20 cases,31.8 ％) and gas-forming pyogenic liver abscess(26 cases,28.6 ％)(P＜0.05).Conclusion The complications of hepatic venous thrombosis,gas-forming and infection in diabetes patients with KPLA were associated with glycemic uncontrolled.
