    Aims: This case-control study aims to identify risk factors for Klebsiella endophthalmitis in patients with Klebsiella sepsis.

    Methods: This is a retrospective case control study. The study population consisted of all patients with positive blood cultures for Klebsiella, admitted to Changi General Hospital (Singapore) from August 2004 to July 2005. The cases were patients who developed Klebsiella endophthalmitis and the controls were those who did not. The potential risk factors analysed included age, sex, race, the total white cell count at presentation; the maximum temperature response; co-morbid pathologies; presence of severe infection; site of primary infection; antibiotic sensitivity of the bacteria strain; and the systemic antibiotics treatment regime.

    Results: One hundred and thirty three consecutive patients with Klebsiella bacteraemia proven by blood culture were included in this study. 5 patients (3.8%) developed endophthalmitis. Klebsiella endophthalmitis was significantly associated with liver abscesses as the primary site of infection (p<0.001); and disseminated intravascular coagulation (DIVC) (p=0.010) on both univariate and multivariate analysis. Diabetes mellitus and other co-morbid pathologies, race and the maximum temperature response were not risk factors for the occurrence of endophthalmitis.

    Conclusions: Liver abscess and disseminated intravascular coagulation are risk factors for endogenous endophthalmitis in patients with Klebsiella sepsis.
