BACKGROUND Persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is associated with high mortality rates, but no treatment strategy has yet been established. We performed this study to evaluate the efficacy of linezolid with or without carbapenem in salvage treatment for persistent MRSA bacteremia. METHODS All adult patients with(More)
BACKGROUND Blood levels of voriconazole, a first line therapy for invasive aspergillosis, may correlate with adverse events and treatment response. However, no randomized controlled studies have been conducted to evaluate the clinical utility of routine therapeutic drug monitoring (TDM) of voriconazole. This study aimed to determine whether routine TDM of(More)
STUDY DESIGN We performed a retrospective review of 126 cases of infectious spondylodiscitis over a 4-year period. OBJECTIVE Differentiation between pyogenic spondylodiscitis (PS) and tuberculous spondylodiscitis (TS) is essential for deciding on the appropriate therapeutic regimen. The aim of this study was to compare the characteristics of the 2 forms(More)
Human leukocyte antigen allele (HLA)-B*5701 is associated with abacavir hypersensitivity. However, the carriage rate of HLA-B*5701 has rarely been studied in Asians. In 534 Korean patients with human immunodeficiency virus infection, HLA-B*5701 status was determined by polymerase chain reaction with HLA-B*5701-specific primers. No patients had the(More)
The whole-blood interferon-gamma enzyme-linked immunosorbent assay (QuantiFERON-TB Gold [QFT-G]; Cellestis, Carnegie, Australia) has been studied mainly for diagnosing active pulmonary tuberculosis (TB) or latent TB. We prospectively evaluated its diagnostic usefulness in patients suspected with extrapulmonary TB (EP-TB). Of the 100 adult patients with(More)
BACKGROUND High prevalence of severe atazanavir-associated hyperbilirubinemia in Asians with low prevalence of the UDP-glucuronosyltransferase (UGT)1A1*28 polymorphism suggests the importance of genetic factors other than UGT1A1*28 for atazanavir-associated hyperbilirubinemia in these populations. METHODS Serum bilirubin levels were measured in 129 Korean(More)
We used several molecular typing methods to analyze 196 methicillin-resistant Staphylococcus aureus (MRSA) and 139 methicillin-susceptible S. aureus (MSSA) isolates collected between 1996 and 2005. The sequence type 72 MRSA has increased in frequency in the community in the Republic of Korea and in hospitals in recent years.
Information about the genotype of varicella-zoster virus (VZV) is useful to monitor outbreaks of vaccine strains. However, in South Korea, where varicella vaccine was introduced in 1988, there are limited data about the genotype of VZV. VZV was isolated from vesicular lesions of patients with herpes zoster or varicella in South Korea between January 2007(More)
BACKGROUND The low reactivity of the tuberculin skin test limits its clinical use in immunocompromised patients with extrapulmonary tuberculosis. A recently developed T-cell-based assay for diagnosing tuberculosis infection gave promising results. However, there were few data on the usefulness of this assay for diagnosing extrapulmonary tuberculosis in(More)
We investigated the kinetics of serologic responses to Middle East respiratory syndrome coronavirus (MERS-CoV) infection by using virus neutralization and MERS-CoV S1 IgG ELISA tests. In most patients, robust antibody responses developed by the third week of illness. Delayed antibody responses with the neutralization test were associated with more severe(More)
