RESUMO

BACKGROUND: Complex femoropopliteal artery disease represents a challenge. The Supera stent holds the promise of improving the results of endovascular therapy for complex femoropopliteal disease. AIMS: We aimed at appraising the early and long-term effectiveness of the Supera stent after successful subintimal angioplasty (SuperSUB strategy) for complex femoropopliteal lesions. METHODS: We conducted a multicenter, prospective, single-arm observational study including consecutive patients at participating centers in whom Supera was implanted after successful subintimal angioplasty for complex femoropopliteal lesions. RESULTS: A total of 92 patients were included Femoropopliteal arteries were the most common target, and lesion length was 261 ± 102 mm. Most procedures were technically demanding, with antegrade femoral access in 35 (38%) and retrograde distal access in 55 (60%). Supera stent length was 281 ± 111 mm, with 4, 5, and 6 mm devices being most commonly used: 32 (35%), 35 (38%), and 23 (25%), respectively. Technical success was achieved in 100% of subjects, as was clinical success (per subject), whereas procedural success (per subject) was obtained in 98%. At 24 months, freedom from clinically driven target lesion revascularization was 93%, whereas primary patency was 87%. When compared with a similar historical cohort, Supera stent use appeared to be associated with a reduction in resources. CONCLUSION: Use of Supera stent after successful subintimal recanalization of complex lower limb arterial lesions yields favorable procedural results, which are maintained over follow-up, and are associated also with a favorable resource use profile.

RESUMO

BACKGROUND: Asthma, with several phenotypes and endotypes, is considered particularly suited for precision medicine. The identification of different non-invasive biomarkers may facilitate diagnosis and treatment. Recently, Staphylococcus aureus and its enterotoxins (SE) have been found to have a role in inducing persistent type 2 airway inflammation in severe asthma, but also in such comorbidities as chronic rhinosinusitis with nasal polyposis (CRSwNP). METHODS: The aim of this retrospective study was to evaluate the prevalence of SE-IgE sensitization in a multicentric Italian cohort of severe asthmatic patients and correlate it with demographic and clinical characteristics. RESULTS: A total of 249 patients were included in the analysis, out of which 25.3% were staphylococcal enterotoxin B (SEB)-IgE positive. We found a meaningful association between SEB-IgE and female gender, a positive association was also measured between CRS and CRSwNP. No significant association was found between SEB-IgE sensitization and atopy, the occurrence of exacerbations and corticosteroid dosages. In the SEB-IgE-positive patient, blood eosinophil count does not appear to be correlated with the severity of the disease. Patients with SEB-IgE sensitization are, on average, younger and with an earlier disease onset, thus confirming the possibility to consider SEB-IgE sensitization as an independent risk factor for developing asthma. CONCLUSIONS: Our data confirm that the search for SE in the initial screening phase of these patients is helpful to better phenotype them, may predict the evolution of comorbidities and lead to a targeted therapeutic choice; in this point of view this represents a goal of precision medicine.

RESUMO

BACKGROUND: Severe asthma impacts quality of life (QoL), including dyspnea, sleep, and activity limitation. Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukins-4 and -13, which are key and central drivers of type 2 inflammation. Phase 3 LIBERTY ASTHMA VENTURE (NCT02528214) and LIBERTY ASTHMA TRAVERSE open-label extension (NCT02134028) evaluated dupilumab 300 mg vs placebo every 2 weeks for 24 weeks (VENTURE) and dupilumab only for an additional 48 to 96 weeks (TRAVERSE) in patients with oral corticosteroid (OCS)-dependent severe asthma. OBJECTIVE: To assess dupilumab's impact on Asthma QoL Questionnaire (AQLQ) items related to breathing symptoms, sleep, and activity limitation, and on OCS reduction. METHODS: The proportion of patients with AQLQ scores of 6 or 7 for breathing symptoms-, sleeping-, and activity-related items in VENTURE and TRAVERSE, together with OCS dose reductions in VENTURE. RESULTS: In VENTURE, significantly greater proportions of dupilumab- vs placebo-treated patients achieved scores of 6 or 7 by week 24 in breathing symptoms-related (42.7%-60.2% vs 22.4%-39.3%), sleeping-related (45.6%-65.0% vs 27.1%-47.7%), and activity-related (44.7%-51.5% vs 22.4%-34.6%) AQLQ items. Improvements were maintained through TRAVERSE in the dupilumab/dupilumab group and increased to dupilumab treatment levels in the placebo/dupilumab group. Significant OCS dose reductions were observed in VENTURE; up to 90% and 60% of dupilumab-treated vs 65% and 41% of placebo-treated patients with AQLQ scores of 6 or 7 in breathing symptoms-, sleeping-, and activity-related items achieved greater than or equal to 50% dose reduction and eliminated OCS at week 24, respectively. CONCLUSION: In patients with severe OCS-dependent asthma, dupilumab improved QoL related to breathing symptoms, sleep, and activity limitation, and reduced OCS use. TRIAL REGISTRATION: ClinicalTrials.gov Identifiers: NCT02528214 and NCT02134028.

RESUMO

BACKGROUND: Biologics are currently one of the main treatment options for a number of diseases. The IgG4 monoclonal antibody dupilumab targets the Interleukin-4 receptor alpha chain, thus preventing the biological effects of the cytokines IL-4 and IL-13, that are essential for the Th2 response. Several controlled trials showed that dupilumab is effective and safe in patients with atopic dermatitis (AD), severe asthma and chronic rhinosinusitis with nasal polyps (CRSwNP), thus resulting in approval by regulatory agencies. Aim of the study was to evaluate the efficacy and safety of dupilumab in adult patients with CRSwNP stratified by common overlapping comorbid conditions. METHODS: We performed a multicenter, observational, prospective study enrolling adult patients with severe CRSwNP who had started dupilumab treatment in the context of standard care from January 2021 to October 2021. Data were collected from twentynine Italian secondary care centers for allergy and clinical immunology, all of which were part of the Italian Society of Allergy, Asthma and Clinical Immunology (SIAAIC). A number of efficacy parameters were used. Patient data were compared using the Wilcoxon test for paired data. All statistical analyses were performed with SPSS version 20 (IBM, Armonk, NY, USA). RESULTS: In total, 82 patients with nasal polyposis were identified. A significant improvement was detected for all the applied efficacy parameters, i.e. 22-item Sino-Nasal Outcome Test (SNOT-22) and bilateral endoscopic nasal polyp score (NPS) scores for CRSwNP, Rhinitis Control Scoring System (RCSS) and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) scores for allergic perennial rhinitis, Forced Expiratory Volume in the 1st second (FEV1) and Asthma Quality of Life Questionnaire (AQLQ) scores for asthma, Eczema Area and Severity Index (EASI) and Dermatology Life Quality Index (DLQI) scores for AD. A non-significant improvement was also obtained in the Urticaria Activity Score over 7 days (UAS7) for chronic spontaneous urticaria. Treatment with dupilumab was well tolerated. CONCLUSIONS: These data suggest that dupilumab treatment in patients suffering from CRSwNP and associated comorbidities may be suitable. Such outcome, although confirmation by trials is warranted, suggests the possibility to treat different disorders with a single therapy, with favorable effects especially under the cost-effectiveness aspect.

RESUMO

BACKGROUND: Allergic rhinitis induced by house dust mites (HDMs) is a highly prevalent but often underdiagnosed and undertreated/untreated chronic disease. It often has a negative impact on sleep, work, leisure activities, and health-related quality of life. Allergen immunotherapy is a proven, safe treatment for respiratory allergies. OBJECTIVE: We sought to assess the efficacy and safety of a 300 index of reactivity (IR) sublingual tablet formulation of Dermatophagoides pteronyssinus:Dermatophagoides farinae 1:1 extract in adolescents (aged ≥12) and adults with moderate to severe HDM-induced allergic rhinitis. METHODS: In a phase III, international, double-blind, placebo-controlled, randomized clinical trial, participants received approximately 12 months of treatment with placebo or the 300 IR tablet. The primary end point was the average total combined score during 4 weeks at the end of the treatment period. RESULTS: A total of 1607 participants were randomized, and 1476 (including 555 [37.6%] with concomitant mild controlled asthma at inclusion) comprised the full analysis set. Over the primary evaluation period, the least squares mean average total combined score in the 300 IR group (3.62) was significantly lower (P < .0001) than in the placebo group (4.35), with a relative least squares mean difference of -16.9% (95% CI, -24.0% to -9.2%). All prespecified secondary end points were consistently improved in the 300 IR group, relative to placebo. The 300 IR tablet was generally well tolerated. Treatment-related adverse events (mainly mild or moderate local reactions) were reported for 51.0% of the patients in the 300 IR group and 14.9% in the placebo group. CONCLUSIONS: The 300 IR sublingual HDM tablet is an effective, safe treatment for HDM-induced allergic rhinitis.

RESUMO

The introduction of personalized medicine (PM) has been a milestone in the history of medical therapy, because it has revolutionized the previous approach of treating the disease with that of treating the patient. It is known today that diseases can occur in different genetic variants, making specific treatments of proven efficacy necessary for a given endotype. Allergic diseases are particularly suitable for PM, because they meet the therapeutic success requirements, including a known molecular mechanism of the disease, a diagnostic tool for such disease, and a treatment blocking the mechanism. The stakes of PM in allergic patients are molecular diagnostics, to detect specific IgE to single-allergen molecules and to distinguish the causative molecules from those merely cross-reactive, pursuit of patient's treatable traits addressing genetic, phenotypic, and psychosocial features, and omics, such as proteomics, epi-genomics, metabolomics, and breathomics, to forecast patient's responsiveness to therapies, to detect biomarker and mediators, and to verify the disease control. This new approach has already improved the precision of allergy diagnosis and is likely to significantly increase, through the higher performance achieved with the personalized treatment, the effectiveness of allergen immunotherapy by enhancing its already known and unique characteristics of treatment that acts on the causes.

RESUMO

Allergen Immunotherapy (AIT) was introduced in clinical practice on an empirical basis more than 100 years ago. Since the first attempts, AIT was administered subcutaneously. Indeed, other routes of administration were proposed and studied, in particular to improve the safety, but only the sublingual route (SLIT) achieved a credibility based on evidence and was then accepted as a viable "alternative" option to the subcutaneous route. SLIT was largely used in clinical trials and clinical practice in this last 30 years. Thus, a large amount of data is available, coming from either controlled trials and postmarketing surveillance studies. It is clear that SLIT is overall effective, but it is also clear that the efficacy is not "class-related," as derived from meta-analyses, but restricted to each specific product. The 30-year lasting use of SLIT allowed to clarify many clinical aspects, such as efficacy, safety, use in asthma, regimens of administration, and optimal doses. In parallel, the mechanisms of action of AIT were elucidated, and new indications were proposed (eg food allergy, atopic dermatitis). In addition, the introduction of molecular-based diagnosis, allowed to better refine the prescription of SLIT, based on specific sensitization profiles. The present article will describe the origin and evolution of SLIT for respiratory allergy, taking into account the clinical context that suggested this form of treatment, the recently developed aspects, the future perspectives and unmet needs, This is not, therefore, a systematic review, rather a narrative historical description of the past history, and a look forward to the future opportunities.

RESUMO

INTRODUCTION: Encephalopathy secondary to hyperammonemia due to Congenital Extra-hepatic Porto-systemic shunt (CEPS) in the absence of liver cirrhosis is an exceptionally unusual condition. We describe the case of a 54-year-old woman admitted to the Emergency Department complaining of recurrent episodes of confusion and worsening cognitive impairment. At admission, the patient displayed slowing cognitive-motor skills with marked static ataxia and impaired gait. Hyperammonemia was detected in the serum. An abdominal computed tomography (CT) excluded portal hypertension and liver cirrhosis, detecting a congenital extra-hepatic porto-systemic shunt which is a highly unusual vascular malformation. The patient was treated by interventional radiologists with a successful endovascular closure. AREAS COVERED: We have performed a review of the last three decades of the literature, starting from the introduction of CT scanning in common clinical practice. Eighteen studies (case reports) described 29 patients with encephalopathy secondary to hyperammonemia due to CEPS in the absence of liver cirrhosis: They underwent treatment similar to our case report of CEPS. EXPERT COMMENTARY: Encephalopathy secondary to hyperammonemia in the absence of hepatic dysfunction is an important diagnostic dilemma to many clinicians. An interventional radiologic approach is currently preferred.

RESUMO

BACKGROUND: Despite availability of clinical guidelines, underdiagnosis, undertreatment, and poor adherence are still significant concerns in allergic rhinitis (AR) therapeutic management. We investigated clinical practice patterns and prescribing behavior of Italian healthcare professionals (HCPs) specialized in AR. METHODS: One-hundred allergologists, 100 ear, nose and throat (ENT) specialists, and 150 general practitioners (GPs) were recruited. The survey assessed: socio-demographic, work experience, monthly caseload, prescription drivers. Next, HCPs were invited to retrospectively recover patients' clinical data to investigate: AR clinical characteristics, therapy management, prescription patterns, patient adherence. Descriptive statistics, Chi square, One-Way analysis of variance, and Two-Way Analysis of Variance were performed. RESULTS: Allergologists visited more AR patients (31% of monthly caseload) than ENTs (21%, p < 0.001), while GPs' caseload was the lowest (6%). Clinical information of 2823 patients were retrieved of whom 1906 (67.5%) suffered from moderate/severe AR (discomfort score: 7.7 ± 1.3) and 917 (32.4%) from mild AR (5.7 ± 1.9). About one-third of mild patients had a discomfort score ≥ 7. Main prescription drivers were "effective on all symptoms" (54.3% patients) and "quick symptom relief" (47.8%), whereas minor drivers were "affordable price" (13.4%) and "refundable" (8.7%). The most prescribed drugs were antihistamines and intranasal corticosteroids (79% and 55% prescriptions), followed by fixed-dose-combination of intranasal azelastine/fluticasone (19%). Polytherapy was the most common treatment strategy (59.6%). HCPs' believe that the majority of the patients was adherent to treatment (88% with score > 7). CONCLUSIONS: This survey describes the therapeutic approach adopted by Italian physicians to cope with AR and shows that HCPs underestimated AR severity and had a non-realistic perception of patients' adherence. These findings suggest that further efforts are required to improve AR clinical management in Italy.

RESUMO

Mepolizumab (anti IL-5, monoclonal antibody) is commercially available in Italy since more than one year for the treatment of severe hypereosinophilic asthma. Its efficacy and safety were evaluated in several regulatory trials. The characteristics of this drug in real life began to be assessed only recently. We describe herein the drop-out rate observed with mepolizumab in real life, because this datum can indirectly reflect the safety and tolerability aspects. The demographic and clinical data of patients receiving mepolizumab for severe asthma were collected, and the number and reasons for discontinuation of the treatment were analyzed. The database involves 143 patients (67 male, age range 19-80 year) who received at least one dose of mepolizumab. The observed discontinuation rate was 6/143 (4.2%). Five out of 6 discontinuations were due to lack of response, and one was an adverse event (urticaria) probably related to the treatment. There was no clinical difference between the drop-out group and the patients still ongoing. As compared to the clinical trials published the discontinuation rate was lower in our population, especially for adverse events (7% vs 23.7%). Thus, the tolerability of mepolizumab, as derived from discontinuations, seems to be better in real-life than in clinical trials.

RESUMO

BACKGROUND: Severe asthma is a disease with a heavy socio-economic burden and a relevant impact on the life of patients. Mepolizumab (MEP) was recently introduced in practice. The previous data were favourable as efficacy and safety are concerned. Nowadays, we can report the clinical data after more than one year of use of MEP in the real-life setting. OBJECTIVE: To evaluate the efficacy and safety of MEP in a real life framework, mainly concerning asthma exacerbations, steroid dependence, effects on respiratory function and adverse events. METHODS: This retrospective analysis was performed on 138 patients, treated with MEP for at least 12 months, and referred to eleven severe asthma clinics in Italy. All patients met the criteria for severe uncontrolled asthma according to ATS/ERS guidelines and prescribing MEP conditions according to the Italian Drug Agency (AIFA). RESULTS: We could observe 138 patients (78 female, age 58 ±â€¯10 years). The average age of onset of asthma was 34 ±â€¯16 years. The blood eosinophil count decreased from 822 ±â€¯491/µL at baseline to 117 ±â€¯96/µL (p < .0001) after 12 months of therapy. Exacerbations decreased from 3.8/year to 0.7/year (-81%; p < .0001). Steroid-dependent patients before MEP (80%) with a daily dose of 10.1 ±â€¯9.4 mg prednisone decrease at 28% after 12 months with a mean of 2.0 ±â€¯4.2 mg/day (p < .0001). The occurrence of adverse events was overall low. CONCLUSIONS & CLINICAL RELEVANCE: In this real-life setting, MEP confirmed its efficacy and safety profile, already shown in clinical trials. This was apparent concerning exacerbation rate, systemic steroids intake and safety.

RESUMO

OBJECTIVE: Allergen-specific immunotherapy (AIT) in its subcutaneous and sublingual forms is currently a well-established and experimentally supported treatment for respiratory allergy and hymenoptera venom allergy. There have been advances in its use linked strictly to the advancement in the knowledge of the molecular mechanisms of allergy, the production of well-characterized extracts, and diagnostic techniques. The use of AIT in asthma and the application of new approaches are expanding. We briefly review the advances and concerns in the use of AIT. DATA SOURCES: PubMed and Scopus. STUDY SELECTIONS: The most recent and clinically relevant literature was selected and reviewed. RESULTS: The introduction of high-quality products supported by large dose-finding trials has yielded better defined indications, contraindications, and modalities of use. Some specific products in tablet form have recently been approved in the United States. Sublingual immunotherapy has been found to be effective in asthma, which until recently had been a matter of debate. Another promising therapy is oral and sublingual desensitization for food allergy, for which encouraging results have recently been reported. In the near future, other options will be available, including new routes of administration (intralymphatic and epicutaneous), allergoids, engineered allergens, and peptides. The use of component-resolved diagnosis techniques will further refine and target AIT prescriptions. CONCLUSION: This condensed and updated review shows that AIT remains a viable treatment option, especially after the introduction of standardized tablets for some allergens. Food allergy and new administration routes represent a promising expansion.

RESUMO

BACKGROUND: Allergic Rhinitis (AR) is a high-prevalence disease. In Europe about 25% of the general population is affected, and in Italy the prevalence is estimated to be 19.8%. The Allergic Rhinitis and its Impact on Asthma (ARIA) international document underlined that the prevalence of severe or refractory or overlapping rhinitis is increasing and represents a non-negligible socio-economic burden. In general, despite the social healthcare costs, allergic rhinitis remains underestimated, not sufficiently controlled and often undertreated. AIM OF THE STUDY: In this multi-center Italian observational and prospective study we assessed the control of AR in patients (> 16 years) without previous asthma diagnosis, referred to Allergy Centers. METHODS: Patients of both sexes and older than 16 with rhinitis symptoms and without asthma were studied. A Visual Analogue Scale (VAS) and the CARAT (Control of Allergic Rhinitis and Asthma Test) were used as patient reported outcome. The possible causes of poor control of AR, as per protocol, were assessed accordingly. RESULTS: We observed 250 patients in a real-life setting: more than 60% of them had an uncontrolled AR, only about 50% used multiple medications, and only a minority were receiving allergen immunotherapy. CONCLUSION: This survey, conducted in a real-life setting, confirmed that AR is overall poorly controlled. The VAS assessment well correlates with the structured CARAT questionnaire and with the relevant symptoms of AR.

RESUMO

ABSTRACT: Allergen immunotherapy (AIT) is the only disease-modifying treatment approved for allergic rhinitis and allergic asthma and represents a suitable therapeutic option, especially in childhood, to modify the progression of respiratory allergic diseases. Starting from the previous "generic class effect" evaluation, as testified by the numerous meta analyses, AIT is now considered a product-specific pathogenic-oriented treatment. BACKGROUND: AIT was empirically proposed more than one century ago in the subcutaneous form (SCIT), but the IgE-mediated mechanism of allergy was elucidated only after 50 years of clinical use of the treatment. The sublingual administration (SLIT) was developed during the 1980 ties, to achieve an improvement in safety and convenience. While SCIT is approved in the United States for the treatment of asthmatic patients with more than 12 years, so far few trials evaluated the clinical efficacy and safety of SLIT in children with allergic asthma, although the indications and some aspects remain unclear. Certainly, due to compliance problems, the age below 3 years may be reasonably considered a practical contraindication. CONCLUSIONS: Given that some specific AIT products are effective and approved as drugs (AIFA, EMA, FDA), the use in children is still debated. Some aspects still need robust confirm: (a) the safety of AIT in asthma; (b) the optimal regimen of administration; (c) the role of AIT as preventative treatment for asthma development.

RESUMO

BACKGROUND: Saline nasal irrigation is labelled as an add-on treatment in patients with allergic rhinitis (AR). The primary aim of this study was to compare the efficacy of 21-day use of buffered hypertonic saline (BHS) versus normal saline solution (NSS) on reducing nasal symptoms in children with seasonal AR (SAR). Comparing their efficacy on nasal cytology counts (NCC), quality of life, and sleep quality was the secondary aim. METHODS: In this 21-day, open-label, randomized controlled study, 36 SAR children (aged 6-13 years) with a Total 5 Symptom Score (T5SS) ≥5 received twice-daily BHS or NSS delivered through a nasal douche. Efficacy measures were least square mean changes (LSmc) in T5SS, NCC, Paediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ), and Pittsburgh Sleep Quality Index (PSQI) scores. RESULTS: BHS improved the T5SS total score to a greater extent than NSS (LSmc -6.45 vs. -5.45, p < 0.001). Concerning NCC, BHS significantly reduced the scores of neutrophils (LSmc -0.76, p = 0.004) and eosinophils (LSmc -0.46, p = 0.018), while NSS did not. Similarly, only BHS yielded a significant improvement in the PRQLQ score (LSmc -0.57, p = 0.009), whereas the improvement in PSQI score was comparable between the BHS (LSmc -0.77, p = 0.025) and NSS (LSmc -1.39, p < 0.001) groups. Overall, BHS was well tolerated. CONCLUSIONS: In children with SAR, BHS is effective in improving nasal symptoms and NCC, with an associated beneficial effect on quality of life.

RESUMO

The recent advances in the knowledge of immunological aspects of many pulmonary diseases, allowed to identify cells, biological functions, cytokines, and receptors that are preferentially involved in each disease. This is the case of asthma, where IL-13 (together with IL-4) is recognized as a central mediator. The role of IL-13 is strictly related, via complex signaling pathways, to eosinophil recruitment and activation, to mucus secretion, periostin generation and to fibrogenic processes (which are part of the remodeling process). These peculiar roles of IL-13 have suggested the hypothesis of its role in Idiopathic Pulmonary Fibrosis, and consequently of its antagonists in the treatment of such disease. We review herein the immunological roles of IL-13 in asthma and IPF, and the currently ongoing attempts to treat IPF by IL-13 antagonism strategies.

RESUMO

OBJECTIVE: Pharmacists play a relevant role in the real-life management of asthma because they are a first-line referral for patients. In fact, the role of pharmacies has been underlined and evidenced also in guidelines. Nonetheless, the true effect of pharmacy-based management of asthma has been assessed in only a few studies. We review the available literature on asthma management in a territorial pharmacy setting. DATA SOURCES: The literature was searched for the keywords pharmacy, bronchial asthma, control, and management. STUDY SELECTIONS: The available studies were subdivided into observational and interventional and described. RESULTS: Seven observational studies and 14 interventional trials were found, involving approximately 20,000 individuals. Most of those studies were performed in Europe and Australia. A high proportion of patients had poorly controlled asthma in the observational studies. The active involvement of pharmacists, in the interventional trials, consistently led to an improvement of the quality of life, a better inhalation technique, and a reduction of exacerbations. CONCLUSION: The literature analysis confirms the relevance of the role of pharmacists in the real-life management of bronchial asthma and underlines the need for a more specific training for those health care professionals.

RESUMO

Asthma, allergic rhinitis (AR) and atopic dermatitis are very common in young people, but in the latest decades it was increasingly recognized that also individuals of higher ages, including the population over 65 years, are concerned. Actually, it is now acknowledged the aging does not considerably alter the immune response to allergens. Allergen immunotherapy (AIT) is the only treatment that works on the causes of allergy, but elderly people are commonly excluded from AIT, except the cases of insect sting allergy. A number of recent studies showed that aged individuals also successfully respond to AIT for respiratory allergy. Therefore, there is no reason to exclude elder patients from AIT. Anyhow, clinical conditions that are considered absolute or relative contraindications are quite frequent in this aged population, thus the risk/benefit ratio must be carefully evaluated for each patient, taking into account that the more frequent occurrence of co-morbidities and the consequent need of daily-based multidrug regimen can favor adverse effects. An important issue concern the ability of AIT, and particularly of sublingual immunotherapy, to significantly improve the quality of life, that often is particularly impaired in the elderly, reducing symptoms and drugs consumption.

RESUMO

Life expectancy and the number of elderly people are progressively increasing around the world. Together with other pathologies, allergic diseases also show an increasing incidence in geriatric age. This is partly due to the growing emphasis on a more accurate and careful diagnosis of the molecular mechanisms that do not allow to ignore the real pathogenesis of many symptoms until now unknown, and partly to the fact that the allergic people from 20 years ago represent the elderly population now. Moreover, environmental pollution predisposes to the onset of allergic asthma and dermatitis which are the result of internal pathologies more than the expression of allergic manifestations. At the same time the food contamination permits the onset of allergic diseases related to food allergy. In this review we provide the state of the art on the physiological changes in the elderly responsible for allergic diseases, their biological characteristics and the major immunological and extra immunological mechanisms. Much emphasis is given to the management of several diseases in the elderly, including anaphylactic reactions. Moreover, some new features are discussed, such as management of asthma with the support of physical activity and the use of the AIT as prevention of respiratory diseases and for the purpose of a real and long lasting benefit. The mechanisms of adverse reactions to drugs are also discussed, due to their frequency in this age, especially in polytherapy regimens. Study of the modifications of the immune system is also of great importance, as regards to the distribution of the lymphocytes and also the presence of a chronic inflammatory disease related to the production of cytokines, especially in prevision of all the possible therapies to be adopted to allow an active and healthy aging.
