With increasing clinical emergence of multidrug-resistant Gram-negative pathogens and the paucity of new agents to combat these infections, colistin (administered as its inactive prodrug colistin methanesulfonate [CMS]) has reemerged as a treatment option, especially for critically ill patients. There has been a dearth of pharmacokinetic (PK) data available(More)
Antimicrobial resistance in Streptococcus pneumoniae remains a serious concern worldwide, particularly in Asian countries, despite the introduction of heptavalent pneumococcal conjugate vaccine (PCV7). The Asian Network for Surveillance of Resistant Pathogens (ANSORP) performed a prospective surveillance study of 2,184 S. pneumoniae isolates collected from(More)
OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) is highly prevalent in hospitals in many Asian countries. Recent emergence of community-associated (CA) MRSA worldwide has added another serious concern to the epidemiology of S. aureus infections. To understand the changing epidemiology of S. aureus infections in Asian countries, we performed a(More)
RATIONALE Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) remain important causes of morbidity and mortality. Increasing antimicrobial resistance has aroused the concern of the failure of antibiotic treatment. OBJECTIVES To determine the distribution of the bacterial isolates of HAP and VAP, their antimicrobial resistance(More)
Diagnosis of dengue infection during the febrile stage has been challenging. We evaluated the accuracy of NS1 protein detection in diagnosing dengue infection in patients presenting with acute febrile illness in Bangkok, Thailand. Of the 235 subjects presented with fever of unknown source within 5 days, 132 (56.2%) were male with the median age of 17.8(More)
The distribution of Burkholderia pseudomallei in soil collected from four regions of Thailand and the frequency of B. pseudomallei infections in patients attending government hospitals throughout Thailand in 1997 were surveyed. A total of 3,585 soil samples collected from 896 sites in four regions of Thailand were cultured for B. pseudomallei using(More)
BACKGROUND Cases of ventilator-associated pneumonia (VAP) due to multidrug-resistant (MDR) Acinetobacter baumannii and Pseudomonas aeruginosa are common in hospitalized patients at Siriraj Hospital, Bangkok, Thailand. Parenteral colistimethate sodium (CMS) has been used for therapy of VAP caused by MDR A. baumannii and P. aeruginosa at Siriraj Hospital over(More)
Community-acquired pneumonia (CAP) is an important cause of mortality and morbidity amongst adults in the Asia-Pacific region. Literature published between 1990 and May 2010 on the clinical and economic burden of CAP amongst adults in this region was reviewed. CAP is a significant health burden with significant economic impact in this region. Chronic(More)
BACKGROUND New strategies in the treatment of febrile neutropenic patients have been proposed during the past decade. It is more and more widely accepted that febrile neutropenic patients are a heterogeneous population and they have varying risks for complications and death. However, most of the data have been collected from patients in Western countries.(More)
Burkholderia pseudomallei is an environmental saprophyte that has been isolated widely from soil in Southeast Asia and the relationship between environmental contamination and clinical melioidosis has been established. It has been shown that the arabinose assimilation property of B. pseudonrallei is probably one of the determinants indicating virulence of(More)
