    Capsular serotypes K1 and K2 of Klebsiella pneumoniae are thought to the major virulence determinants responsible for liver abscess. The intestine is one of the major reservoirs of K. pneumoniae, and epidemiological studies have suggested that the majority of K. pneumoniae infections are preceded by colonization of the gastrointestinal tract. The possibility of fecal-oral transmission in liver abscess has been raised on the basis of molecular typing of isolates. Data on the serotype distribution of K. pneumoniae in stool samples from healthy individuals has not been previously reported. This study investigated the seroepidemiology of K. pneumoniae isolates from the intestinal tract of healthy Chinese in Asian countries. Stool specimens from healthy adult Chinese residents of Taiwan, Japan, Hong Kong, China, Thailand, Malaysia, Singapore, and Vietnam were collected from August 2004 to August 2010 for analysis.

    BACKGROUND: It has been unclear as to whether the Rome II criteria could be applied to patients in the Asia region with functional gastrointestinal (GI) diseases. The aim of the present study was to determine if symptoms of Asian patients with functional gastrointestinal disorders formed groups which corresponded to the Rome II diagnostic criteria.

    METHODS: A modified English version of Talley's bowel disease questionnaire was developed in collaboration with various research teams in accordance with the Rome II criteria. This instrument was translated into the local languages of the following nine Asian regions: China, Hong Kong, Indonesia, Korea, Malaysia, Singapore, Taiwan, Thailand and Vietnam. From September to December 2001, newly enrolled outpatients attending 14 GI or medical clinics in these regions were invited to complete the questionnaire. From these respondents, patients with functional gastrointestinal disorders fulfilling the '12 weeks out of 12 months' criteria were separated for further analysis. Principal component factor analysis with varimax rotation was used to identify symptom clusters or factors. These factors were compared with the existing classification of functional GI diseases derived from the Rome II criteria.

    RESULTS: Factor analysis of symptoms from 1012 functional GI patients supported the Rome II classification of the following groups of functional GI disorders: diarrhea-predominant irritable bowel syndrome, functional constipation, functional dyspepsia, functional abdominal pain syndrome, functional heartburn, and functional vomiting. Functional diarrhea was combined with functional anorectal disorders, and globus merged with functional dysphagia into one factor. Some of the functional dyspepsia, abdominal bloating and belching symptoms were loaded into one factor.

    CONCLUSIONS: Factor analysis of symptoms from a sample of Asian patients with functional GI disorders partially supported the use of the Rome II classification.

    OBJECTIVES: To determine antimicrobial stewardship (AMS) programme practices in Asian secondary- and tertiary-care hospitals.

    METHODS: AMS programme team members within 349 hospitals from 10 countries (Cambodia, India, Indonesia, Japan, Malaysia, Pakistan, the Philippines, Taiwan, Thailand and Vietnam) completed a questionnaire via a web-based survey link. The survey contained questions as to whether 12 core components deemed essential for AMS programmes were implemented.

    RESULTS: Overall, 47 (13.5%) hospitals fulfilled all core AMS programme components. There was a mean positive response rate (PRR) of 85.6% for the responding countries in relation to a formal hospital leadership statement of support for AMS activities, but this was not matched by budgeted financial support for AMS activities (mean PRR 57.1%). Mean PRRs were ≥80.0% for the core AMS team comprising a physician or other leader responsible for AMS activities, a pharmacist and infection control and microbiology personnel. Most hospitals had access to a timely and reliable microbiology service (mean PRR 90.4%). Facility-specific antibiotic treatment guidelines for common infections (mean PRR 78.7%) were in place more often than pre-authorization and/or prospective audit and feedback systems (mean PRR 66.5%). In terms of AMS monitoring and reporting, PRRs of monitoring specific antibiotic use, regularly publishing AMS outcome measures, and the existence of a hospital antibiogram were 75.1%, 64.4% and 77.9%, respectively.

    CONCLUSIONS: Most hospitals participating in this survey did not have AMS programmes fulfilling the requirements for gold standard AMS programmes in hospital settings. Urgent action is required to address AMS funding and resourcing deficits.
