Hundreds of studies over the last 4 decades have produced evidence to support the following: (1) risk stratification allows the identification of a subset of patients who may be safely managed as outpatients given the right health care environment; (2) antibacterial prophylaxis for high-risk patients who remain neutropenic for 7 days prevents infections and decreases mortality; (3) the empirical management of febrile neutropenia with a single antipseudomonal beta-lactam results in the same outcome and less toxicity than combination therapy using aminoglycosides; (4) vancomycin should not be used routinely empirically either as part of the initial regimen or for persistent fever, but rather should be added when a pathogen that requires its use is isolated; (5) empirical antifungal therapy should be added after 4 days of persistent fever in patients at high risk for invasive fungal infection (IFI); the details of the characterization as high risk and the choice of agent remain debatable; and (6) preemptive antifungal therapy in which the initiation of antifungals is postponed and triggered by the presence, in addition to fever, of other clinical findings, computed tomography (CT) results, and serological tests for fungal infection is an acceptable strategy in a subset of patients. Many practical management questions remain unaddressed. Evidence-based medicine creating a sometimes confusing amalgam of letters and numbers to Practicing evidenced-based medicine means “integrating individual rank the strength of a given recommendation and the quality of the clinical expertise with the best available external clinical evidence from evidence on which the recommendation is based (Table 2). For example, the very first Infectious Diseases Society of systematic research has produced evidence applicable to the particular America (IDSA) guideline for the management of febrile neutrope- case. The key point is the qualifier “best,” meaning that the evidence nia (FN) had a simple “star rating scheme similar to that used for has to be appraised, which is not easy.

This chapter provides a review and comments on a selection of the evidence-based guidelines for fever and neutropenia published The “right” hierarchy of evidence is a matter of academic debate, recently. The terminology used by the guidelines issued by the although the principles are agreed upon: a properly conducted European Society for Medical Oncology (ESMO),14 the IDSA,15 the randomized controlled trial (RCT) is usually better evidence than an National Comprehensive Cancer Network (NCCN)16 and the Ameri- observational study, which is generally better than a case series, can Society of Clinical Oncology (ASCO)17 are presented on Table 2.

These are notable for being the first fever and neutropenia guide- This example uses the ranking proposed by the Oxford-based lines that explicitly use the Grades of Recommendation Assessment, Centre for Evidence-based Medicine (CEBM). The When confronted with a clinical decision, instead of personally sieving GRADE framework (http://www. EBM’s most universal system to formulate and grade evidence-based practice important concept is that any recommendation must be supported by guidelines. It explicitly separates “strength of recommendation” evidence and that the quality of the evidence must be made explicit. Recommendations can only be “strong” or “weak” (based on Professional organizations have indeed embraced some form of whether the desirable effects of the recommendation outweigh the assessment of the evidence in their published guidelines.

NCS Page 4 of 71 Final Report Update 1 Drug Effectiveness Review Project INTRODUCTION Allergic rhinitis is a condition characterized by sneezing, watery rhinorrhea, nasal 1 itching, congestion, itchy palate, and itchy, red, and watery eyes. The prevalence of allergic rhinitis has increased significantly over the last 15 years and the disease currently affects twenty 2 to forty million Americans. It is estimated that in 2002, approximately 14 million medical office 2 visits were attributed to allergic rhinitis. Many suffering from allergic rhinitis are children and 3 young adults, whom, if treated early, may avoid later stage complications. If left untreated, this condition could lead to the development or worsening of comorbidities including chronic or 4, 5 recurrent sinusitis, asthma, otitis media, an respiratory infections. Moderate to severe allergic 3, 5 rhinitis may also lead to sleep disorders, fatigue, and learning problems. Rhinitis can be divided into 2 broad categories: allergic and non-allergic. Allergic rhinitis consists of seasonal and perennial rhinitis. Seasonal allergic rhinitis, also called hay fever, is characterized by symptoms that occur in response to specific seasonally occurring allergens. Allergens may include pollen from trees, grasses, and weeds. Perennial allergic rhinitis occurs throughout the year and is caused by allergens such as house dust mites, animal dander, cockroaches, and molds. In some geographic locations, pollen can play a role in perennial rhinitis. Patients are often sensitized to both seasonal and perennial allergens, which can be 6 termed mixed allergic rhinitis. There is a prominent genetic component involved in the development of allergic rhinitis. Individuals with both parents suffering from atopic disease have a 50% or greater chance of 5 affliction with allergic disease. The symptoms of allergic rhinitis are caused by an IgE-mediated immune response to a particular allergen.

HIV and Cardiac Diseases ACHIM BARMEYER, MARKUS UNNEW EHR With growing age and duration of the disease, the prevalence of cardiovascular dis- eases is increasing in HIV+ patients. The increase of cardiovascular morbidity results from an elevated cardiovascular risk profile as well as being a direct consequence of HIV infection itself. Knowledge of the diagnosis and therapy of HIV-associated cardiovascular disease is becoming more and more important (Neumann 2002a, Dakin 2006). Coronary artery disease (CAD) HIV+ patients show a higher prevalence of CAD (Currier 2003) and a higher inci- dence of acute coronary syndromes (ACS) (Klein 2002, Triant 2007), especially acute myocardial infarctions (MI), compared to HIV-negative individuals. It also appears that cardiovascular events occur earlier. The higher cardiovascular morbidity might be attributable to three possible major causes: negative effects of ART, a direct impact of HIV infection and a higher cardiovascular risk profile. The effect of ART on cardiovascular morbidity was investigated in a number of studies. ART was associated with a higher incidence of CAD (Currier 2003), the development of atherosclerosis (Jericó 2006, de Saint Martin 2006) and incidence of coronary vascular events (Iloeje 2005). In the D:A:D study, including more than 23,000 patients, a 26% increase in MI incidence was found with each year of ART exposure (Friis-Moller 2003, Law 2006). Antiretroviral therapy was an independent risk factor for CAD along with the classical cardiovascular risk factors like age, gender and par- ticularly smoking (Law 2006).
