[Invasive liver abscess syndrome caused by Klebsiella pneumoniae, case series].

Primary liver abscesses caused by Klebsiella pneumoniae and their related systemic complications produce the invasive liver abscess syndrome due to Klebsiella pneumoniae. To describe the clinical, epidemiological and evolution characteristics in our center. A retrospective cohort of hospitalized adults in Hospital Italiano de Buenos Aires between January 1st, 2001 and May 1st, 2020. We included patients with diagnosis of abscess in any organ with rescue in culture or positive blood culture for Klebsiella pneumoniae. Epidemiological, clinical characteristics and prognosis of those with hepatic primary localization were analyzed. 10 patients were included. Two (20%) patients were Oriental. Median age was 69 years (interquartile range 64-79), nine (90%) were men. The most frequent comorbidity was type 2 diabetes (40%). Four (40%) patients had spread to other organs. The median hospitalization was 21.5 days (IIC 15-43), 60% (n: 6) were hospitalized in the intensive care unit and 30% (n: 3) died. The invasive liver abscess syndrome due to Klebsiella pneumoniae is a rare life-threatening disease. Our study reports the characteristics of patients with this syndrome in our population.
