Global strategy for asthma management and prevention: GINA executive summary

Asthma is a serious health problem throughout the world. During the past two decades, many scientific advances have improved our understanding of asthma and ability to manage and control it effectively. However, recommendations for asthma care need to be adapted to local conditions, resources and services. Since it was formed in 1993, the Global Initiative for Asthma, a network of individuals, organisations and public health officials, has played a leading role in disseminating information about the care of patients with asthma based on a process of continuous review of published scientific investigations. A comprehensive workshop report entitled “A Global Strategy for Asthma Management and Prevention”, first published in 1995, has been widely adopted, translated and reproduced, and forms the basis for many national guidelines. The 2006 report contains important new themes. First, it asserts that “it is reasonable to expect that in most patients with asthma, control of the disease can and should be achieved and maintained,” and recommends a change in approach to asthma management, with asthma control, rather than asthma severity, being the focus of treatment decisions. The importance of the patient–care giver partnership and guided self-management, along with setting goals for treatment, are also emphasised.

Common characteristics of upper and lower airways in rhinitis and asthma: ARIA update, in collaboration with GA(2)LEN.

This update aimed to review the new evidence available to support or refute prior Allergic Rhinitis and its Impact on Asthma (ARIA) statements. A Medline search of publications between 2000 and 2005 was conducted, with articles selected by experts. New evidence supports previous ARIA statements, such as: (i) allergic rhinitis (AR) is a risk factor for asthma; (ii) patients with persistent rhinitis should be evaluated for asthma; (iii) most patients with asthma have rhinitis; (iv) a combined strategy should be used to treat the airways and (v) in low‐ to middle‐income countries, a different strategy may be needed. The increased risk of asthma has also been found among sufferers from non‐AR. Recent reports show AR is a global problem. Many studies demonstrated parallel increasing prevalence of asthma and rhinitis, but in regions of highest prevalence, it may be reaching a plateau. Factors associated with a reduced risk of asthma and AR have been identified, confirming previous findings of protection related to exposure to infections. Treatment of rhinitis with intranasal glucocorticosteroids, antihistamines, leukotriene antagonists or immunotherapy may reduce morbidity because of asthma. To take advantage of the paradigm of unified airways, there is a need to rationalize diagnosis and treatment to optimize management.

Pharmacologic and anti-IgE treatment of allergic rhinitis ARIA update (in collaboration with GA2LEN)

The pharmacologic treatment of allergic rhinitis proposed by ARIA is an evidence‐based and step‐wise approach based on the classification of the symptoms. The ARIA workshop, held in December 1999, published a report in 2001 and new information has subsequently been published. The initial ARIA document lacked some important information on several issues. This document updates the ARIA sections on the pharmacologic and anti‐IgE treatments of allergic rhinitis. Literature published between January 2000 and December 2004 has been included. Only a few studies assessing nasal and non‐nasal symptoms are presented as these will be discussed in a separate document.

Allergic rhinitis management pocket reference 2008

Allergic rhinitis is a major chronic respiratory disease because of its prevalence, impacts on quality of life and work/school performance, economic burden, and links with asthma. Family doctors (also known as ‘primary care physicians’ or ‘general practitioners’) play a major role in the management of allergic rhinitis as they make the diagnosis, start the treatment, give the relevant information, and monitor most of the patients. Disease management that follows evidence‐based practice guidelines yields better patient results, but such guidelines are often complicated and may recommend the use of resources not available in the family practice setting. A joint expert panel of the World Organization of Family Doctors (Wonca), the International Primary Care Airways Group (IPAG) and the International Primary Care Respiratory Group (IPCRG), offers support to family doctors worldwide by distilling the globally accepted, evidence‐based recommendations from the Allergic Rhinitis and its Impact on Asthma (ARIA) initiative into this brief reference guide.

Eosinophil chemotaxis by chemokines: a study by a simple photometric assay.

Background: The effects of a panel of 15 chemokines on eosinophil chemotaxis were studied by a new photometric assay which is both less tedious and less laborious than the conventional manual counting methods. Approximately 40 chemokines have been identified to date, but there is little information on the eosinophil migration‐inducing ability of chemokines other than CC chemokine receptor (CCR) 3 ligands.

Effect of cytokines on mediator release from human dispersed lung mast cells

To evaluate the contribution of human lung mast cells (HLMC) to allergic inflammation, we investigated whether or not cytokines, including stem‐cell factor (SCF), monocyte chemotactic and activating factor (MCAF), and RANTES, activate HLMC. SCF induced histamine release from dispersed HLMC in a dose‐dependent fashion (P<0.01). The release was 7.8 ± 1.0% at 500 ng/ml SCF (n= 9). This response was also observed in chopped lung tissue. HLMC from which surface IgE molecules had been removed by treatment with lactic acid responded to SCF, while these cells lost their response to anti‐IgE. The process was relatively rapid and reached a maximum in 5 min. This response required extracellular calcium, and it was observed at 37°C, but not at 4°C or 20°. A brief preincubation (10 min) with lower concentrations of SCF, which were ineffective in releasing histamine, enhanced anti‐IgE‐induced histamine release (P<0.05), while its enhancing effect was lost by the longer preincubation (30 min). SCF did not prime basophils to enhance stimulated‐histamine release. Interleukin (IL)‐1α, IL‐1β, IL‐3, IL‐4, IL‐5, granulocyte/macrophage‐colony stimulating factor (GM‐CSF), MCAF, and RANTES neither induced histamine release nor enhanced the release stimulated by anti‐IgE after a 10‐ or 30‐min preincubation. The combination of IL‐3 and IL‐4 showed no effect on histamine release from HLMC. Leukotriene (LT)C4/D4/E4 production by SCF was negligible, as compared with anti‐IgE‐induced LT production. SCF at 1.5 ng/ml augmented anti‐IgE‐induced LT generation significantly (536+ 117 pg/105 mast cells and 1569 ± 258 pg/105 mast cells; P<0.01). These results provide further evidence that numerous aspects of the phenotype of mast cells and basophils are heterogeneous, including structure, relevant secretagogues, and pharmacologic control.
