BACKGROUND Delamanid (OPC-67683), a nitro-dihydro-imidazooxazole derivative, is a new antituberculosis medication that inhibits mycolic acid synthesis and has shown potent in vitro and in vivo activity against drug-resistant strains of Mycobacterium tuberculosis. METHODS In this randomized, placebo-controlled, multinational clinical trial, we assigned 481(More)
RATIONALE The increasing worldwide incidence of extensively drug-resistant tuberculosis (XDR-TB) has emerged as a threat to public health and tuberculosis (TB) control. Treatment outcomes have varied among studies, and data on long-term survival are still scarce. OBJECTIVES To retrospectively assess the burden, clinical characteristics, treatment(More)
BACKGROUND Treatment of multidrug resistant tuberculosis (MDR-TB) is lengthy, toxic, expensive, and has generally poor outcomes. We undertook an individual patient data meta-analysis to assess the impact on outcomes of the type, number, and duration of drugs used to treat MDR-TB. METHODS AND FINDINGS Three recent systematic reviews were used to identify(More)
The influx of macrophages into the lungs is the major component of the granulomatous response to infection with Mycobacterium tuberculosis. In this investigation we used flow cytometric analysis to define macrophage populations entering the airways and lung tissues of infected mice. We demonstrate that by the judicious use of cell surface markers,(More)
Linezolid is used off-label to treat multidrug-resistant tuberculosis (MDR-TB) in absence of systematic evidence. We performed a systematic review and meta-analysis on efficacy, safety and tolerability of linezolid-containing regimes based on individual data analysis. 12 studies (11 countries from three continents) reporting complete information on safety,(More)
To determine whether long-term outcome differs between acute respiratory distress syndrome (ARDS) resulting from pulmonary (ARDSp) and extrapulmonary (ARDSexp) causes. Observational study. Medical intensive care unit of a university hospital. Twenty-nine ARDS patients (16 ARDSp and 13 ARDSexp) who survived over 6 months after diagnosis. The two groups did(More)
BACKGROUND Acute exacerbation (AE) in idiopathic pulmonary fibrosis (IPF) is increasingly recognized as a relatively common and highly morbid clinical event. However, clinical data on AE in non-IPF interstitial pneumonia are sparse. This study was performed to find the frequency, clinical features, and outcome of AE in non-IPF interstitial pneumonia.

OBJECTIVES A recently developed bronchoalveolar lavage (BAL) galactomannan (GM) assay shows promising results. We evaluated the diagnostic performance of this assay and analyzed risk factors for false-positive results. METHODS A prospective cohort study was performed in a tertiary hospital over a 9-month period. We reviewed all adult patients who(More)
This study was conducted to evaluate treatment outcome, mortality, and predictors of both in patients with multidrug-resistant tuberculosis (MDR-TB) at 3 TB referral hospitals in the public sector of Korea. We included MDR-TB patients treated at 3 TB referral hospitals in 2004 and reviewed retrospectively their medical records and mortality data. Of 202(More)
BACKGROUND We investigated the prevalence of latent tuberculosis infection (LTBI) among the health care workers (HCWs) and analyzed its risk factors in South Korea. METHODS A standard questionnaire regarding the baseline demographics and risk factors for LTBI was given to each participant and tuberculin skin test (TST), QuantiFERON-TB GOLD In-Tube(More)
