Abstract:
Objective:To analyze the clinical features of patients with invasive Klebsiella pneumoniae liver abscess syndrome (IKLAS). Methods:The clinical data of 12 patients diagnosed as IKLAS in Zhuzhou Central Hospital from January 2020 to January 2023 were retrospectively analyzed.Results:Among 12 patients there were 6 males and 6 females with an mean age of 65.3±12.2 years (49-90). Nine patients were complicated with type 2 diabetes. The main clinical manifestations were fever ( n=9), chill ( n=6), shiver ( n=4), nausea and vomiting ( n=2), upper abdominal pain ( n=2), fatigue and anepithymia ( n=2), cough and expectoration ( n=1), disturbance of consciousness ( n=1) and hemoptysis ( n=1). The leukocyte count was increased in 8 cases, lymphocyte count decreased in 10 cases, and platelets count decreased in 3 cases. C-reactive protein and procalcitonin levels were elevated, while serum albumin levels were lowered in all patients. The alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were increased in 7 cases each. Liver abscess was located in the right lobe in 8 cases, in the left lobe in 1 cases, and in both lobes in 3 cases. There were 7 patients with single abscess, and 5 patients with multiple abscesses. The etiology was confirmed by liver pus culture ( n=10) and blood culture ( n=5), respectively. The main sites of invasion were lung and blood stream ( n=10 and n=5, respectively). The majority of Klebsiella pneumoniae isolates were antibiotic sensitive strains and the overall drug resistance rate was relatively low. All patients were given antibiotics, and 10 of them also received liver abscess puncture drainage. After treatment, 11 patients were discharged, and 1 died of septic shock. Conclusions:Patients with IKLAS exhibit diverse clinical symptoms, most patients are complicated with diabetes, and the main sites of invasion are in the lungs and blood stream. Timely diagnosis, active screening of extrahepatic infection sites, effective drainage of abscess and appropriate antibiotic treatment can improve the survival of patients.
