Abstract :

Pyogenic liver abscess (PLA) is a significant, though uncommon, cause of morbidity in the United States. Recently, Klebsiella has emerged as an important cause of PLA. We analyzed the clinical course, microbiology, and treatment outcomes of patients discharged with PLA. In addition, we sought to examine the incidence of and risk factors for Klebsiella liver abscess (KLA). We identified 49 cases of PLA. Abscess cultures were positive in 23 (48%) patients. The mean age of the pts was 56 years (range: 20–83 years). Sixty percent were male. The most frequent conditions associated with PLA were intra–abdominal infections (ten cases; 20%), diabetes mellitus (nine cases; 18%) and malignancy (nine cases; 18%). Klebsiella was the most commonly isolated species from the abscess cultures (seven cases; 30% of all positive abscess cultures). We used univariate and logistic regression analyses to identify the risk factors for KLA. Controlling for age, only malignancy was identified in our study as a risk factor for a Klebsiella liver abscess. Klebsiella is emerging as an important cause of liver abscesses. Malignancy may be an important risk factor for Klebsiella liver abscess.
