Adherence issues related to sublingual immunotherapy as perceived by allergists

Objectives: Sublingual immunotherapy (SLIT) is a viable alternative to subcutaneous immunotherapy to treat allergic rhinitis and asthma, and is widely used in clinical practice in many European countries. The clinical efficacy of SLIT has been established in a number of clinical trials and meta-analyses. However, because SLIT is self-administered by patients without medical supervision, the degree of patient adherence with treatment is still a concern. The objective of this study was to evaluate the perception by allergists of issues related to SLIT adherence. Methods: We performed a questionnaire-based survey of 296 Italian allergists, based on the adherence issues known from previous studies. The perception of importance of each item was assessed by a VAS scale ranging from 0 to 10. Results: Patient perception of clinical efficacy was considered the most important factor (ranked 1 by 54% of allergists), followed by the possibility of reimbursement (ranked 1 by 34%), and by the absence of side effects (ranked 1 by 21%). Patient education, regular follow-up, and ease of use of SLIT were ranked first by less than 20% of allergists. Conclusion: These findings indicate that clinical efficacy, cost, and side effects are perceived as the major issues influencing patient adherence to SLIT, and that further improvement of adherence is likely to be achieved by improving the patient information provided by prescribers. © 2010 Scurati et al, publisher and licensee Dove Medical Press Ltd

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

The TRE3 research project: A hybrid timber-frame wall system for emergency housing facilities

The TRE3 research project focuses on the development of a new and innovative timber frame wall modulus for emergency housing facilities. The wall modulus, in this paper referred to as Hybrid Timber Frame (HTF) wall system, is an evolution of the traditional Light-Frame Timber (LFT) structural systems and combines the advantages and some peculiar aspects of lightweight structures to the potentialities of Cross-Laminated Timber (CLT) panels. This hybrid approach makes the HTF structural system suitable for the production of light and high-performing wall moduli, allowing an advanced prefabrication process, fast assembling procedures and a simple disassembly. The paper provides a description of the HTF wall system following a multidisciplinary approach. Particular attention is paid to the mechanical and geometrical characterisation of three HTF wall moduli, used to assemble different housing units. The structural design is carried out by considering severe loading conditions (which include snow, wind and earthquake) so that the temporary units assembled with the HTF moduli can be used in most of the Italian regions. Furthermore, in this paper, specific aspects such as logistics, architectural details and building physics are analysed and critically discussed

[Restrospective analysis of the renal biopsy activity in Piedmont]

The Piedmont Group of Clinical Nephrology has compared the activity of 18 nephrology centers in the region Piedmont/Valle d'Aosta with regard to renal biopsy (RB). Data on the RBs performed in every nephrology unit, taking into account their entire experience (in some cases spanning more than 30 years), were analyzed. 3396 RBs were performed between 1996 and 2011. Thirty to forty percent were done in patients aged >-65 years (1568 in patients >-65 years, 29 in patients >-85 years). 598 BRs were performed in children over the last 20 years. The following contraindications to RB were considered: chronic renal failure by 8 centers (44.4%), serum creatinine (SCr >3 mg/dL) by 3 centers, longitudinal renal size 2 mg/dL and 275 in patients on dialysis. The percentage of RBs performed in patients with SCr >2 mg/dL ranged from 27% to 55% between centers. As regards RB in the course of acute renal failure in an ANCA-positive context, 4 centers allowed administration of corticosteroids and 8 centers administration of immunosuppressive treatment as well, even in the absence of histological data. In drug-related nephropathies, RB was considered indicated to confirm the farhypothesis of immunoallergic interstitial nephropathy either if the responsible drug was not among the traditional ones known to induce tubulo-interstitial renal disease or if the pharmacological hypothesis seemed no longer sufficient to justify the renal presentation. All centers but one were against performing RB in case of atheroembolic disease. Three centers performed RB in the intensive care unit. As regards RB in patients undergoing treatment with anticoagulants, aspirin was discontinued 5-14 days before the procedure (mean 8 days) and given again 7-15 days afterwards (mean 11.4 days). Ten centers replaced the anticoagulants with low-dose heparin, which was discontinued the day before the procedure; 11 centers asked advice from cardiologists. RB was repeated in 113 cases after a delay of 1 month to 8 years from the first RB. Our analysis shows uniformity in the approach to RB in this Italian region, with some differences compared with the literature: particular attention was paid to severely critical patients, elderly patients, and patients treated with anticoagulant drugs

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
