RESUMO
OBJECTIVE: Asthma is a disease with elevated prevalence within the general population. Although general practitioners (GPs) are among the first health-care professionals to whom patients refer for their symptoms, there are few evaluations of this disease based on data provided by the GPs. The aim of this observational study is to assess the impact of asthma and comorbid allergic rhinitis on individual/social burden, quality of life, and disease control in asthmatic patients of Italian GPs. METHODS: Throughout Italy, 107 GPs enrolled 995 patients diagnosed with asthma and using anti-asthmatic drug prescriptions, or with asthma-like symptoms during the previous 12 months. Data were collected through questionnaires filled out by GPs and patients. RESULTS: Of the 995 asthmatic patients, 60.6% had concomitant allergic rhinitis (R+A), 39.4% had asthma alone. The latter, compared to those with R+A, showed significantly lower prevalence of intermittent asthma (37.5% vs. 55.6%) and higher prevalence of mild, moderate, and severe persistent asthma (28.4% vs. 23.2%, 28.7% vs. 18.8%, and 5.4% vs 2.4%, respectively). Individual/social burden due to asthma was frequent and increased with disease severity: 87.5% of severe persistent asthma patients reported at least one medical consultation in the last 12 months, 37.5% emergency department visits, 26.7% hospitalization, and 62.5% limitations in daily activities. Control and quality of life were inversely associated with disease severity and were worse in patients with R+A than in those with asthma alone. CONCLUSIONS: This study showed the negative impact of high severity levels and comorbid allergic rhinitis on quality of life of asthmatic patients and on individual/social burden due to asthma in an Italian GPs setting.

BACKGROUND: Although general practitioners (GPs) are frequently the first healthcare professionals whom asthma patients refer to for their symptoms, few studies have explored the extent of adherence to guidelines for asthma management based on data provided directly by GPs. Aims of the present study were to assess drug prescriptions for asthma by GPs and to evaluate prescriptive adherence to GINA guidelines (GL) and its relationship with disease control in real life. METHODS: 995 asthmatic patients (45% males, mean age 43.3⯱â¯17.7â¯yrs) were enrolled by 107 Italian GPs distributed throughout the country. Data on diagnosis, disease severity, prescribed anti-asthmatic drugs and control were collected through questionnaires filled out by GPs taking into consideration the 2009 GINA Guidelines. Data on drug use and chronic sinusitis, nasal polyposis, chronic bronchitis, emphysema were reported by patients through a self-administered questionnaire. RESULTS: The large majority of patients were classified by GPs as having intermittent (48.4%) or mild persistent asthma (25.3%); 61% had co-morbid allergic rhinitis (AR). The prevalent therapeutic regimen used by patients was a combination of inhaled corticosteroids (ICS) plus long-acting ß2-agonists (LABA) (54.1%), even in the intermittent/mild persistent group. ICS as mono-therapy or in combination with other drugs but LABA, was the second most frequently adopted treatment (14.4%). In general, the GPs adherence to GL treatment indications was 28.8%, with a significant association with a good asthma control (OR 1.85, 95% CI 1.18-2.92). On the other hand, comorbidity (OR 0.52, 95% CI 0.32-0.84), moderate (0.44, 0.28-0.69) and severe (0.06, 0.02-0.20) persistent asthma showed significant negative effects on asthma control. CONCLUSIONS: Our results show that over-treatment of intermittent/mild persistent asthma is frequent in the GPs setting while therapeutic regimens are more appropriately applied for moderate/severe asthma. In general, we found low adherence to GINA GL treatment recommendations even if its relevance in asthma control was confirmed.

PURPOSE OF REVIEW: A 1-year systematic review in the field of ocular allergy was carried out to select new information which may be useful for a practical approach to allergic conjunctivitis. RECENT FINDINGS: Out of the 56 articles listed by PubMed, 27 papers were included in the review following a consensus achieved among the authors who had independently reviewed all abstracts. Selected articles were classified according to their main focus: antihistamines, omalizumab, new treatments for vernal keratoconjunctivitis and inflammatory ocular disorders, and sublingual immunotherapy. SUMMARY: The data reviewed are discussed with the aim of underlining unmet needs and making recommendations for future studies on diagnosis and treatment of ocular allergy which may better guide clinical practice in this important area of allergy and clinical immunology.

PURPOSE OF REVIEW: This article intends to be a systematic review of papers published during 2003-2004 quoted in a Medline search for 'hygiene hypothesis'. The worldwide perspective of the article does not refer just to a geographical concept, but tries also to address the question of whether the consensus on the hypothesis is global or whether it applies to all types of allergic or immunologic disease, to any age sample or infectious agent. Furthermore, the article outlines those clinical and experimental studies which, in the authors' opinion, may represent significant contributions to a better understanding of the hygiene hypothesis and may guide further investigations on the subject. RECENT FINDINGS: The association between a reduced exposure to infectious agents (as a part of a changed lifestyle) and a higher prevalence of atopy seems now to be confirmed by consistent evidence. Mechanisms underlying this association, however, are not yet completely clear (immune deviation or immune regulation). SUMMARY: Further experimental and clinical studies are needed, with special reference to the time, duration and intensity of exposure to any specific infectious agent which is related to well-defined allergy outcomes. The background information for using microbial products in allergy prevention and treatment is still limited.

AIM: The aim of the study was to evaluate the link between the severity of upper and lower airways diseases in mite allergic patients with respiratory allergy. PATIENTS AND METHOD: A multicentre, observational, cross-sectional study was carried out in 556 consecutively enrolled mite allergic patients with rhinitis and asthma comorbidity attending a specialist unit. Severity assessment of rhinitis and asthma was evaluated in accordance with ARIA and GINA guidelines. RESULTS: Reliable data were available for 518 patients. The distribution of rhinitis severity was: 15.6% mild intermittent rhinitis, 4.4% moderate-severe intermittent rhinitis, 30.3% mild persistent rhinitis and 49.6% moderate persistent rhinitis. The distribution of asthma severity was: 41.3% mild intermittent asthma, 14.3% mild persistent asthma, 19.1% moderate persistent asthma and 25.3% severe persistent asthma. In patients with moderate-severe persistent rhinitis (49.5%) a significant trend (p = 0.005) was found pointing to an increased link with asthma severity. CONCLUSION: A link between respective severities of rhinitis and asthma was found in only half of mite allergic patients with rhinitis and asthma.

Skin prick testing is an essential test procedure to confirm sensitization in IgE-mediated allergic disease in subjects with rhinoconjunctivitis, asthma, urticaria, anapylaxis, atopic eczema and food and drug allergy. This manuscript reviews the available evidence including Medline and Embase searches, abstracts of international allergy meetings and position papers from the world allergy literature. The recommended method of prick testing includes the appropriate use of specific allergen extracts, positive and negative controls, interpretation of the tests after 15 - 20 minutes of application, with a positive result defined as a wheal ≥3 mm diameter. A standard prick test panel for Europe for inhalants is proposed and includes hazel (Corylus avellana), alder (Alnus incana), birch (Betula alba), plane (Platanus vulgaris), cypress (Cupressus sempervirens), grass mix (Poa pratensis, Dactilis glomerata, Lolium perenne, Phleum pratense, Festuca pratensis, Helictotrichon pretense), Olive (Olea europaea), mugwort (Artemisia vulgaris), ragweed (Ambrosia artemisiifolia), Alternaria alternata (tenuis), Cladosporium herbarum, Aspergillus fumigatus, Parietaria, cat, dog, Dermatophagoides pteronyssinus, Dermatophagoides farinae, and cockroach (Blatella germanica). Standardization of the skin test procedures and standard panels for different geographic locations are encouraged worldwide to permit better comparisons for diagnostic, clinical and research purposes.
RESUMO
AIM: To evaluate the impact of a medical education course (MEC) on the behaviour of general practitioners (GPs) to treat asthma and allergic rhinitis (AR). METHODS: Data on 1820 patients (mean age 41 yrs ± 17 yrs) with asthma or AR were collected by 107 Italian GPs: 50% attended a MEC and 50% didn't (group B). The adherence for AR and asthma treatment was evaluated according to ARIA and GINA guidelines (GL). RESULTS: AR and asthma were diagnosed in 78% and 56% of patients; 34% had concomitant AR and asthma. Regardless of the MEC, the adherence to GL was significantly higher for AR than for asthma treatment (52 versus 19%). Group B GPs were more compliant to ARIA guidelines in the treatment of mild AR, whereas group A were more compliant in the treatment of moderate-severe AR; the adherence didn't differ between the groups for AR patients with comorbid asthma. Adherence to GINA GL for asthma treatment did not differ between GPs of groups A and B, independently from concomitant AR. Though insignificantly, group A were more compliant to GINA GL in the treatment of patients with only severe persistent asthma (63 versus 46%) as group B were for patients with severe persistent asthma and concomitant AR. CONCLUSIONS: GPs often tend to treat patients independently from GL. The impact of a single MEC did not improve adherence to GL in treating less severe AR and asthma patients, while there was a trend towards the opposite attitude in more severe AR patients without concomitant asthma.
