OBJECTIVES The purpose of this study was to evaluate the impact of inappropriate antimicrobial therapy on the outcome of patients with hospital-acquired pneumonia (HAP) caused by Acinetobacter baumannii. METHODS All cases of HAP caused by A. baumannii from January 2000 to March 2006 at the Samsung Medical Center (Seoul, Korea) were analyzed(More)
OBJECTIVES To investigate the impact of imipenem resistance on the mortality rate among patients with Acinetobacter bacteraemia. METHODS A retrospective, pairwise-matched (1:1), risk-adjusted (age, Pitt bacteraemia score) cohort study was performed at three tertiary care hospitals in Korea from January 2000 to June 2005. RESULTS Forty patients with(More)
We evaluated posaconazole serum concentrations and hepatotoxicity in 12 leukemia patients who transitioned from posaconazole suspension to tablets. Patients who switched to tablets had significantly increased posaconazole concentrations (median: suspension, 748 ng/ml; tablet, 1,910 ng/ml; P < 0.01) without clinically relevant hepatotoxicity.
This study compares the effectiveness of the Pitt bacteremia score, the Charlson weighted index of comorbidity, and the Acute Physiology and Chronic Health Evaluation II (APACHE II) scoring systems for the prediction of mortality in intensive care unit (ICU) patients with sepsis using the retrospective observational method on 134 patients with ICU-acquired(More)
We investigated the characteristics of 48 carbapenem-resistant Acinetobacter baumannii isolates collected from 5 tertiary care hospitals in Korea by multilocus sequencing typing, pulsed-field gel electrophoresis, and polymerase chain reaction amplification of the antimicrobial resistance determinants. We identified 2 distinct main clones of(More)
A Gram-positive, rod-shaped bacterium, designated strain LBY(T), was isolated from the blood of a Korean patient. The organism could not be identified based on conventional clinical microbiological methods. 16S rRNA gene sequencing and phylogenetic analysis revealed that it belonged to the genus Paenibacillus, but was distinct from recognized Paenibacillus(More)
Chronic active Epstein-Barr virus (CAEBV) infection is characterized by persistent infectious mononucleosis-like symptoms, an unusual pattern of Epstein-Barr virus (EBV) antibodies, detection of the EBV genome in affected tissues or peripheral blood, and chronic illness that cannot be attributed to any other known disease. This is the first reported Korean(More)
Prevalence and characteristics of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in Korean hospitals were assessed. A total of 1484 clinical Enterobacteriaceae isolates were collected from 8 tertiary-care hospitals in various regions of Korea over a 3-month period (June to August) in 2005. Among 546 Klebsiella pneumoniae isolates, 123(More)
Aberrant activations of Fms-like tyrosine receptor kinase (FLT) 3 are implicated in the pathogenesis of 20% to 30% of patients with acute myeloid leukemia (AML). G-749 is a novel FLT3 inhibitor that showed potent and sustained inhibition of the FLT3 wild type and mutants including FLT3-ITD, FLT3-D835Y, FLT3-ITD/N676D, and FLT3-ITD/F691L in cellular assays.(More)
Although a decrease in acquired immunodeficiency syndrome (AIDS)-related mortality has been documented in highly active antiretroviral therapy (HAART) era, there are no published data comparing specific causes of death between pre-HAART and HAART era in Korea. Mortality and cause of death were analyzed in three treatment periods; pre-HAART (1990-1997),(More)
