OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA), originally restricted to hospitals, has emerged as a significant pathogen in the community. Although MRSA accounts for over 60% of S. aureus in tertiary hospitals in Korea, little is known about the epidemiology of community-associated MRSA (CA-MRSA). METHODS From January to July 2005, a(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)
Staphylococcus aureus, one of the most frequently isolated pathogens in both hospitals and the community, has been particularly efficient at developing resistance to antimicrobial agents. As methicillin-resistant S. aureus (MRSA) has prevailed and, furthermore, as S. aureus with reduced susceptibility to vancomycin has emerged, the therapeutic options for(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)
The proportion of tuberculosis manifested by immune reconstitution inflammatory syndrome (IRIS) after HAART has not been established. We describe the incidence and clinical features of tuberculosis manifested by IRIS after HAART in an intermediate tuberculosis burden area. The findings suggest that a significant proportion of the tuberculosis occurring(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)
Korea is a low prevalence country for human immunodeficiency virus (HIV) infection and has an intermediate tuberculosis (TB) burden. We previously reported that the incidence of TB in HIV-infected patients was 9.6 cases per 100 person-years (P-Y) between 1988 and 1997. The aims of the present study were to measure any change in incidence from the previous(More)
Methicillin-resistant Staphylococcus aureus (MRSA) accounts for more than 70% of S. aureus isolates from tertiary hospitals in Korea. Clinical isolates of S. aureus were collected from eight provincial, university-affiliated hospitals during the period from June 1999 to January 2001 for nationwide surveillance. All isolates were screened for reduced(More)
OBJECTIVE Tuberculosis (TB) is an important opportunistic infection in HIV patients. Immune responses to Mycobacterium tuberculosis in HIV/TB patients were evaluated. METHODS Fifteen patients with HIV/TB, ten with HIV, four with TB, and five controls were enrolled. Peripheral blood mononuclear cells were isolated and stimulated with mycobacterial antigen(More)
