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)
BACKGROUND Clinical outcomes of spontaneous bacterial peritonitis (SBP) due to extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella species (ESBL-EK) have not been adequately investigated. METHODS We conducted a retrospective matched case-control study to evaluate the outcomes of SBP due to ESBL-EK compared with those due to(More)
The prevalence of transmitted resistance to antiretroviral drugs varies geographically, with little known about this effect in Asia. In Korea, zidovudine has been widely administered, without charge, through the National AIDS program since the early 1990s; with other potent antiretroviral agents also being introduced in the late 1990s. An analysis of 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)
To assess the effect of liver dysfunction on the production of C-reactive protein (CRP), CRP levels were evaluated in patients with Escherichia coli bacteremia with or without liver cirrhosis (LC). Thirty patients of each kind were selected as case and control groups, respectively. A matched control of 30 LC patients without acute infection was also(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)
OBJECTIVES To evaluate the incidence of early syphilis based on time from initiation of highly active antiretroviral therapy (HAART) in human immunodeficiency virus (HIV)-infected patients. STUDY DESIGN Five hundred thirty-nine HIV-positive patients undergoing HAART were followed up to 4 years to identify early (primary or secondary) syphilis. Incidence(More)
Little is known about the effect of immune reconstitution inflammatory syndrome (IRIS) on the long-term clinical outcome. Of 52 opportunistic infections (OI) occurring within one year after the start of HAART in 387 HIV patients, 33 (63%) were classified as having IRIS. The patients with IRIS showed no significant difference in the AIDS event-free survival(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)
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)
