Barriers to Asthma Treatment in the United States: Results From the Global Asthma Physician and Patient Survey

BACKGROUND: The Global Asthma Physician and Patient (GAPP) survey evaluated the perceptions of both physicians and patients on the management of asthma. Here we present the results from the United States (US) subpopulation of the GAPP survey. METHODS: The GAPP Survey was a large, global study (physicians, n = 1733; patients, n = 1726; interviews, n = 3459). In the US, 208 adults (aged ≥ 18 years) with asthma and 224 physicians were recruited. Respondents were questioned using self-administered online interviews with close-ended questionnaires. RESULTS: Physician and patient responses were found to differ in regard to perception of time spent on asthma education, awareness of disease symptoms and their severity, asthma medication side effects, and adherence to treatment and the consequence of nonadherence. Comparison of the US findings with the global GAPP survey results suggest the US physician-patient partnership compared reasonably well with the other countries in the survey. Both patients and physicians cited a need for new asthma medication. CONCLUSIONS: Similar to the global GAPP survey, the US-specific findings indicate that in general there is a lack of asthma control, poor adherence to therapy, and room for improvement in patient-physician communication and partnership in treating asthma

Vasoactive intestinal peptide in human nasal mucosa

Vasoactive intestinal peptide (VIP), which is present with acetylcholine in parasympathetic nerve fibers, may have important regulatory functions in mucous membranes. The potential roles for VIP in human nasal mucosa were studied using an integrated approach. The VIP content of human nasal mucosa was determined to be 2.84 +/- 0.47 pmol/g wet weight (n = 8) by RIA. VIP-immunoreactive nerve fibers were found to be most concentrated in submucosal glands adjacent to serous and mucous cells. 125I-VIP binding sites were located on submucosal glands, epithelial cells, and arterioles. In short-term explant culture, VIP stimulated lactoferrin release from serous cells but did not stimulate [3H]glucosamine-labeled respiratory glycoconjugate secretion. Methacholine was more potent than VIP, and methacholine stimulated both lactoferrin and respiratory glycoconjugate release. The addition of VIP plus methacholine to explants resulted in additive increases in lactoferrin release. Based upon the autoradiographic distribution of 125I-VIP binding sites and the effects on explants, VIP derived from parasympathetic nerve fibers may function in the regulation of serous cell secretion in human nasal mucosa. VIP may also participate in the regulation of vasomotor tone

Recommendations for Competency in Allergy Training for Undergraduates Qualifying as Medical Practitioners: A Position Paper of the World Allergy Organization

The global increased prevalence of allergy is such that between 20-30% of the world's population now suffers from some form of allergic disease, with considerable and continuing increases in prevalence over the last three decades [1]. Although the specialty of allergy is practiced and recognized in most developed countries, even some developed countries lack adequate resources to manage the local burden of allergic disease. In many developing countries there are few or no allergy specialists due to either the prevailing healthcare infrastructure, to socio-economic reasons, and/or to the lack of recognition of allergy as a clinical specialty. There is often minimal or no inclusion of allergy education/training in the undergraduate medical curriculum, and this shortfall must be addressed if the increasing burden of allergic diseases is to be managed. The majority of patients with common allergic diseases around the world are treated by primary care physicians, and not by trained specialists. However, a lack of appropriate education and training in allergy at the undergraduate level leaves many medical graduates with low baseline knowledge and skills in the science and practice of allergy. In addition, because it is a relatively new discipline, education and training in allergy in medical schools has lagged behind scientific and clinical developments in this field, and there are few allergy specialists available to teach this multidisciplinary subject. This phenomenon is described by the World Health Organization as the knowledge/practice gap. Unless allergy training is included as an essential part of undergraduate medical education at the clinical level, many physicians will qualify with inadequate competency to manage the diagnosis and treatment of allergic diseases at the primary care level. Thus, a cycle of lack of basic knowledge about the most common allergic diseases, lack of recognition of allergic disease at the clinical level, and inadequate knowledge and skills in the diagnosis and treatment of allergic diseases will be perpetuated. To help break this cycle the World Allergy Organization (WAO) presents broad guidelines for the curriculum of education and training of medical students in the immune mechanisms of allergic responses, and the commonest manifestations of clinical allergy. Inclusion of these educational guidelines into curriculum development will provide medical graduates with the basic knowledge required to recognize and treat common allergic diseases during postgraduate training or as a general practitioner (care level 1), and the knowledge of when to refer the more complex problems to appropriate organ-based or allergy specialists (care levels 2 and 3) [2]. These guidelines outline optimal curriculum content, and are offered for consideration and modification to meet local needs and healthcare provision structures. Although certain immunodeficiency states may accompany allergies or may need to be considered in the differential diagnosis of allergic diseases, this document is not intended to provide a comprehensive guideline on the teaching of immune deficiencies to medical students

Classification of Nonallergic Rhinitis Syndromes With a Focus on Vasomotor Rhinitis, Proposed to be Known henceforth as Nonallergic Rhinopathy

Many patients have nasal syndromes that are nonallergic and noninfectious and not caused by mechanical or anatomic abnormalities. There are at least 8 recognized nonallergic rhinitis syndromes: drug-induced rhinitis including rhinitis medicamentosa, gustatory rhinitis, hormonally induced rhinitis including the rhinitis of pregnancy, nonallergic rhinitis with eosinophilia syndrome, senile rhinitis, atrophic rhinitis, cerebral spinal fluid leak, and vasomotor rhinitis. Few studies have explored etiologic causes. These syndromes are distinguished by clinical characteristics, recognized triggering conditions, and concomitant observations such as nasal eosinophilia or cerebral spinal fluid leak. Until more specific subjective clinical characteristics and/or objective measures can better define and differentiate underlying causes for these disparate diseases, they will remain a murky group of overlapping syndromes.
