Hyperbilirubinemia is frequently observed in Caucasian HIV patients treated with atazanavir. UDP-glucuronosyltransferase 1A1 polymorphism, UGT1A1*28, which is associated with atazanavir-induced hyperbilirubinemia, is less common in Asians than in Caucasians. However, little is known about the incidence of atazanavir-associated hyperbilirubinemia in Asian(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)
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)
Six men (mean age: 36.3 +/- 29 years) infected with the human immunodeficiency virus (HIV), four Japanese and two from Myammar, were admitted to our hospital for treatment of tuberculosis. In five, HIV positivity on serologic testing was first found when tuberculosis was diagnosed. The mean CD4 cell count was 37.3 +/- 29.6/microliters. Results of tuberculin(More)
The purpose of this study was to establish a prediction rule for severe illness in adult patients hospitalized with pandemic influenza A (H1N1) 2009. At the time of initial presentation, the baseline characteristics of those with severe illness (i.e., admission to intensive care unit, mechanical ventilation, or death) were compared to those of patients with(More)
The incidence of specific intracranial parenchymal lesions of HIV-infected patients varies considerably between countries. In the Republic of Korea, the number of HIV-infected patients is increasing, but little is known regarding the spectrum of intracranial parenchymal lesions in these patients. The aim of the present study was to obtain this information.(More)
BACKGROUND Healthcare-associated (HCA) infection has emerged as a new epidemiological category. The aim of this study was to evaluate the impact of HCA infection on mortality in community-onset Klebsiella pneumoniae bloodstream infection (KpBSI). METHODS We conducted a retrospective study in two tertiary-care hospitals over a 6-year period. All adult(More)
BACKGROUND Asymptomatic bacteriuria (ABU) is common and often leads to unnecessary antimicrobial use. Reducing antibiotic overuse for ABU is therefore an important issue for antimicrobial stewardship. We performed this study to investigate the appropriateness of ABU management and to evaluate physicians' knowledge and practice regarding ABU. METHODS We(More)
Disseminated aspergillosis is very rare in immunocompetent hosts and is typically associated with a poor prognosis. We describe the case of a 66-year-old, immunocompetent man who developed pneumonia, endophthalmitis and probable spondylitis caused by Aspergillus species. The patient was successfully treated with antifungal drugs. We reviewed the(More)
Penicillin is the first b-lactam antibiotic and a member of the most widely used group of antibiotics. It has effects against many kinds of microorganisms. Although many types of bacteria are now resistant, penicillin is still one of the most useful antibiotics. Many kinds of adverse reactions to penicillin, such as interstitial nephri-tis, are well known;(More)
