BACKGROUND: Cytomegalovirus (CMV) retinitis is one of the most important tissue-invasive CMV diseases in immunocompromised patients. Since 1980, non-invasive diagnostic methods, notably the CMV antigenemia assay, have been widely used as adjunct tests to diagnose tissue-invasive CMV diseases. However, there are limited data on the diagnostic value of the CMV antigenemia assay for diagnosing CMV retinitis. MATERIALS AND METHODS: We performed a retrospective review of all cases of CMV retinitis at Asan Medical Center, Seoul, South Korea over a 9-year period...

BACKGROUND: The World Health Organization recommends the surveillance of influenza-like illness (ILI) and severe acute respiratory infection (SARI) to respond effectively to both seasonal influenza epidemics and pandemics. In Korea, the "Hospital-based Influenza Morbidity and Mortality (HIMM)" surveillance system has been operated to monitor ILI and SARI occurrences. MATERIALS AND METHODS: A multi-center prospective observational study was conducted. Adult patients with acute respiratory infection (ARI) were enrolled during the 2011-2012, 2012-2013, and 2013-2014 influenza seasons at the 10 university hospitals using the HIMM surveillance system...

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is an important global health problem. Furthermore, the time to identify a positive sputum culture is an important risk factor for the spread of tuberculosis, and several factors can predict a prolonged time to culture conversion. Moreover, the relationship between poor nutritional status and infectious disease is clearly established. Therefore, the present study aimed to investigate the association between body mass index (BMI) and sputum culture conversion within 3 months among patients with MDR-TB...

BACKGROUND: Although adenovirus (ADV) infection occurs steadily all year round in Korea and the identification of respiratory viral coinfections has been increasing following the introduction of multiplex real-time polymerase chain reaction tests, the clinical impact of viral coinfection in children with ADV infection has rarely been reported. MATERIALS AND METHODS: Medical records of children diagnosed with ADV infection were retrospectively reviewed. The enrolled children were divided into two groups based on the identified respiratory viruses: ADV group and coinfection group...

Varicella zoster virus (VZV) is a human neurotropic alphaherpesvirus that causes chickenpox (varicella) in children. VZV reactivation may lead to neurological complications, including transverse myelitis. However, transverse myelitis caused by VZV reactivation is rare in immunocompetent patients. Herein, we report a case of transverse myelitis caused by VZV in an immunocompetent older patient, and confirmed this case by polymerase chain reaction. A 79-year-old woman visited our service with complaints of weakness in the right lower leg, generalized vesicular eruptions, and throbbing pain in the right flank for ten days...

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne disease caused by the newly discovered SFTS Bunyavirus, and there have been no case reports of SFTS patients presenting with hemophagocytic lymphohistiocytosis (HLH) in the English literature. We report a case of SFTS presenting with HLH in a 73-year-old immunocompetent male farmer. Although the patient had poor prognostic factors for SFTS, such as old age and central nervous system symptoms, he recovered fully with supportive care...

There have been a small number of cases of scrub typhus-associated hemophagocytic syndrome (HPS), most of which were treated successfully using adequate antibiotics. Here, we report a case of Epstein-Barr virus (EBV)-associated HPS after scrub typhus infection that was not improved using antirickettsial treatment. A 73-year-old male who had been diagnosed with scrub typhus according to an eschar and a positive serology was transferred to our institution because of a persistent fever despite 7-day doxycycline therapy...

Prosthesis retention is not recommended for multidrug-resistant Acinetobacter prosthetic joint infection due to its high failure rate. Nevertheless, replacing the prosthesis implies high morbidity and prolonged hospitalization. Although tigecycline is not approved for the treatment of prosthetic joint infection due to multidrug resistant Acinetobacter baumannii, its appropriate use may preclude prosthesis exchange. Since the area under the curve divided by the minimum inhibitory concentration is the best pharmacodynamic predictor of its efficacy, we used tigecycline at high dose, in order to optimize its efficacy and achieve implant retention in 3 patients who refused prosthesis exchange...

The efficacy and safety of a single tablet regimen (STR) of elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) were analyzed in Phase 3 clinical trials in antiretroviral therapy (ART)-naïve and ART-experienced Asian subjects infected with human immunodeficiency virus (HIV)-1. Studies GS-US-236-102 and GS-US-236-103 were randomized, double-blind, placebo-controlled, 144-week studies conducted in ART-naïve subjects, comparing E/C/F/TDF versus efavirenz (EFV)/F/TDF or ritonavir-boosted atazanavir (ATV+RTV) plus emtricitabine/tenofovir DF (F/TDF), respectively...

BACKGROUND: Extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-PE) are increasingly reported as pathogens in urinary tract infections (UTIs). However, in Sri Lanka, the clinical and molecular epidemiology of ESBL-PE implicated in UTIs has not been well described. MATERIALS AND METHODS: We conducted prospective, laboratory-based surveillance from October to December 2013 at a tertiary care hospital in southern Sri Lanka and enrolled patients ≥1 year of age with clinically relevant UTIs due to ESBL-PE...

Antibiotic stewardship is a key strategy for limiting antibiotic resistance. Over the last decade the South Korean government has implemented a series of healthcare policies directed to this end, consisting of legislative separation of drug prescribing and dispensing, antibiotic utilization reviews, healthcare quality assessment, and public reporting. As a result, the proportion of antibiotic prescriptions for acute upper respiratory tract infections in primary healthcare facilities decreased from 72.9% in 2002 to 42...

BACKGROUND: The clinical and economic impact of multidrug-resistant (MDR) Acinetobacter baumannii colonization remains unclear. This study aimed to estimate and compare the mortality rates, length of stay (LOS), and hospitalization costs in the intensive care unit (ICU) for MDR A. baumannii colonized patients and a matched population. MATERIALS AND METHODS: We performed a retrospective propensity score matched cohort study comparing the outcomes of patients with MDR A...

Corynebacterium species are non-fermentous Gram-positive bacilli that are normal flora of human skin and mucous membranes and are commonly isolated in clinical specimens. Non-diphtheriae Corynebacterium are regarded as contaminants when found in blood culture. Currently, Corynebacterium striatum is considered one of the emerging nosocomial agents implicated in endocarditis and serious infections. We report a case of native-valve infective endocarditis caused by C. striatum, which was misidentified by automated identification system but identified accurately by 16S ribosomal RNA sequencing, in a 55-year-old male patient...

Abiotrophia defectiva, a nutritionally variant streptococci can cause bacteremia, brain abscess, septic arthritis and in rare cases, infective endocarditis, which accounts for 5-6% of all cases. A. defectiva is characteristically difficult to diagnose and the mortality, morbidity and complication rates are high. Here, we discuss a case of infective endocarditis caused by A. defectiva. A 62-year-old female had previously undergone prosthetic valve replacement 6 years prior to admission. She developed infective endocarditis after tooth extraction...
