Daptomycin (6 mg per kilogram daily) is not inferior to standard therapy for S. aureus bacteremia and right-sided endocarditis. (ClinicalTrials.gov number, NCT00093067 [ClinicalTrials.gov].).
This is part of the series of practice guidelines commissioned by the Infectious Diseases Society of America (IDSA) through its Practice Guidelines Committee. The purpose of this guideline is to provide assistance to clinicians in the diagnosis and treatment of two specific types of urinary tract infections (UTIs): uncomplicated, acute, symptomatic bacterial cystitis and acute pyelonephritis in women. The guideline does not contain recommendations for asymptomatic bacteriuria, complicated UTIs, Foley catheter-associated infections, UTIs in men or children, or prostatitis. The targeted providers are internists and family practitioners. The targeted groups are immunocompetent women. Criteria are specified for determining whether the inpatient or outpatient setting is appropriate for treatment. Differences from other guidelines written on this topic include use of laboratory criteria for diagnosis and approach to antimicrobial therapy. Panel members represented experts in adult infectious diseases and urology. The guidelines are evidence-based. A standard ranking system is used for the strength of the recommendation and the quality of the evidence cited in the literature reviewed. The document has been subjected to external review by peer reviewers as well as by the Practice Guidelines Committee and was approved by the IDSA Council, the sponsor and supporter of the guideline. The American Urologic Association and the European Society of Clinical Microbiology and Infectious Diseases have endorsed it. An executive summary and tables highlight the major recommendations. Performance measures are described to aid in monitoring compliance with the guideline. The guideline will be listed on the IDSA home page at http://www.idsociety.org It will be evaluated for updating in 2 years.
OR DECADES, INFECTIVE ENDOCARditis (IE) caused by Staphylococcus aureus has been viewed primarily as a community-acquired disease, especially associated with injection drug use. [1][2][3][4][5][6][7] In contrast, patients with nosocomial or intravascular catheterassociated S aureus bacteremia were considered to be at low risk for IE. 5,6,[8][9][10][11] S aureus IE is relatively infrequent at any individual institution, and observations of its characteristics were based primarily upon relatively small samples, 1,3,6,9,[12][13][14] single-center experiences, 5,6,8,9,[13][14][15][16] or retrospectively identified patients. 2,7,8,15,16 Patient characteristics, treatment practices, and outcomes in these single-center studiesoftendifferedconsiderably.Moreover, because no large, prospectively col-See also pp 3022 and 3061.
Dental treatment does not seem to be a risk factor for infective endocarditis, even in patients with valvular abnormalities, but cardiac valvular abnormalities are strong risk factors. Few cases of infective endocarditis would be preventable with antibiotic prophylaxis, even with 100% effectiveness assumed. Current policies for prophylaxis should be reconsidered.
In this large, prospective, multinational cohort, more than one half of all cases of non-HACEK gram-negative bacillus endocarditis were associated with health care contact. Non-HACEK gram-negative bacillus endocarditis is not primarily a disease of injection drug users.
S. aureus is an important and common cause of IE. The outcome of SA-NVIE is worse than that of non-SA-NVIE. Several clinical parameters are independently associated with mortality for patients with SA-NVIE. The clinical characteristics and outcome of SA-NVIE vary significantly by geographic region, although the reasons for such regional variations in outcomes of SA-NVIE are unknown and are probably multifactorial. A large, prospective, multinational cohort study of patients with IE is now under way to further investigate these observations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
