A survey of clinical features of allergic rhinitis in adults
Background: Allergic rhinitis (AR) has high prevalence and substantial socio-economic burden.
Material/Methods: The study included 35 Italian Centers recruiting an overall number of 3383 adult patients with rhinitis (48% males, 52% females, mean age 29.1, range 18\u201345 years). For each patient, the attending physician had to fill in a standardized questionnaire, covering, in particular, some issues such as the ARIA classification of allergic rhinitis (AR), the results of skin prick test (SPT), the kind of treatment, the response to treatment, and the satisfaction with treatment.
Results: Out of the 3383 patients with rhinitis, 2788 (82.4%) had AR: 311 (11.5%) had a mild intermittent, 229 (8.8%) a mild persistent, 636 (23.5%) a moderate-severe intermittent, and 1518 (56.1%) a moderate-severe persistent form. The most frequently used drugs were oral antihistamines (77.1%) and topical corticosteroids (60.8%). The response to treatment was judged as excellent in 12.2%, good in 41.3%, fair in 31.2%, poor in 14.5%, and very bad in 0.8% of subjects. The rate of treatment dissatisfaction was significantly higher in patients with moderate-to-severe AR than in patients with mild AR (p<0.0001). Indication to allergen immunotherapy (AIT) was significantly more frequent (p<0.01) in patients with severe AR than with mild AR. .
Conclusions: These fndings confirm the appropriateness of ARIA guidelines in classifying the AR patients and the association of severe symptoms with unsuccessful drug treatment. The optimal targeting of patients to be treated with AIT needs to be reassessed
Intensity, duration, and frequency of post-dialysis fatigue in patients on chronic haemodialysis
Background: Although frequent and debilitating, little is known about the characteristics of post-dialysis fatigue (PDF). Objective: To characterise the intensity, duration and frequency of PDF and the associated variables in patients on chronic haemodialyses. Design: Prospective, observational and multicenter study. Patients: We studied 271 patients. Measurements: Patients were considered to be suffering from PDF if they spontaneously offered this complaint when asked the open-ended question: \u201cDo you feel fatigued after dialysis? Then, each patient was invited to rate the intensity, duration and frequency of PDF from 1 to 5. Results: One hundred sixty-four patients (60.5%) had PDF. The median [95% confidence interval (CI)] scores of PDF intensity, duration and frequency were 3 (3\u20134), 3 (3\u20134) and 4 (4-4), respectively. The median (95% CI) of the sum of the scores (Sum Score) of PDF intensity, duration and frequency was 11 (10\u201312). Seventy four patients had a Sum Score 65 12. Using multiple regression analysis, PDF intensity was associated with dialytic age and ultrafiltration rate (UFR), PDF duration with dialytic age, while PDF fatigue frequency was associated with height. The Sum Score was associated with dialytic age and recovery time and negatively associated with daily activity, height and UFR (ml/kg/h). Conclusion: The intensity, duration and frequency of PDF are high in a large percentage of patients, suggesting that PDF is an intense event in terms of quantity and quality. Understanding the relationship between the variables associated with PDF and its intensity, duration and frequency may help better understand the underlying mechanisms of this burdensome condition
Are IgE levels to food other than rosaceae predictive of allergy in lipid transfer protein-hypersensitive patients?
Background: Lipid transfer protein (LTP), the most frequent cause of primary food allergy in Italy, is a cross-reacting plant pan-allergen. Markers able to predict whether a patient sensitized to a certain food but not
yet clinically allergic will develop allergy would be extremely helpful.
Objective: It was the aim of this study to investigate the relevance of IgE levels to some plant foods other than Rosaceae as predictors of either local or systemic allergic reaction in LTP-allergic subjects.
Methods: One hundred (40 males, 60 females , mean age 29 years) peach-allergic patients monosensitized to LTP seen at 14 Italian centres in 2009 were studied. Walnut, hazelnut, peanut, tomato, rice and/or maize allergy was ascertained by interview and confirmed by positive skin prick test. IgE levels to these foods and to rPru p 3 were measured.
Results: Higher levels of IgE to Pru p 3 were associated with a higher prevalence of allergy to hazelnut, peanut and walnut. For all study foods, except rice, median IgE levels in allergic subjects significantly exceeded those in tolerant subjects, though within single allergic groups, the differences between patients reporting systemic or local (oral) symptoms were not significant. Ninety-five percent cut-off IgE levels predictive of clinical allergy were established for study foods although the marked overlaps between allergic and tolerant subjects made them of limited usefulness.
Conclusion: Specific IgE levels are only partially predictive of clinical allergy. The reasons why some individuals showing low specific IgE levels develop clinical allergy whereas others showing high IgE levels do not, despite similar exposure to the allergen, remain unclear

Epinephrine autoinjector prescription in food-allergic adults: Symptom-based only or allergen-based also? An Italian multi-centre study
Background: Epinephrine is the treatment of choice for acute food-allergic reactions but existing guidelines state that it should be prescribed uniquely to patients who already experienced at least one food-induced anaphylactic episode. Objective: We investigated whether in Italy epinephrine auto-injector is prescribed uniquely following the existing guidelines only, or is allergen-informed as well (i.e., based on the potential risk associated with sensitization to certain food allergens), and hence preventive. Methods: 1110 adult patients (mean age 31 years; M/F 391/719) with food allergy seen at 19 allergy outpatient clinics were studied. Patients with a history of probable anaphylaxis were identified. Subjects were classified as having primary (type 1) and/or secondary (type 2) food allergy and were divided into several subgroups based on the offending allergen/food. Epinephrine prescriptions were recorded and analyzed both as a whole and by sensitizing allergen. Results: Epinephrine was prescribed to 138/1100 (13%) patients with a significant difference between subjects with type-1 and type-2 food allergy (132/522 [25%] vs 6/629 [1%]; p< 0.001). The epinephrine group included most patients with a history of anaphylaxis (55/62 [89%]) or emergency department visits 106/138 (77%). In some specific subsets, namely fish-, tree nuts-, and lipid trasfer protein (LTP)-allergic patients, epinephrine was prescribed to patients without a history of systemic allergic reactions. Conclusions: Italian allergy specialists prescribe epinephrine auto-injectors both on the basis of clinical history of severe reactions and on a critical analysis of the hazard associated with the relevant protein allergens, which suggests a good knowledge of allergens as well as acquaintance with the guidelines for prescription of emergency medication
