Mild/Moderate Asthma Network in Italy (MANI): a long-term observational study.

Objective: The prevalence of asthma in Italy is estimated to be around 4%; it affects approximately 2,000,000 citizens, and up to 80-90% of patients have mild-to-moderate asthma. Despite the clinical relevance of mild-to-moderate asthma, longitudinal observational data are very limited, including data on disease progression (worsening vs. improvement), the response to treatment, and prognosis.

SIRM-SIAAIC consensus, an Italian document on management of patients at risk of hypersensitivity reactions to contrast media.

Hypersensitivity reactions (HRs) to contrast media (CM) can be distinguished in immune-mediated (including allergic reactions) and non-immune-mediated reactions, even if clinical manifestations could be similar. Such manifestations range from mild skin eruptions to severe anaphylaxis, making it important for radiologists to know how to identify and manage them. A panel of experts from the Società Italiana di Radiologia Medica e Interventistica (SIRM) and the Società Italiana di Allergologia, Asma e Immunologia Clinica (SIAAIC) provided a consensus document on the management of patients who must undergo radiological investigations with CM.

Urticaria: recommendations from the Italian Society of Allergology, Asthma and Clinical Immunology and the Italian Society of Allergological, Occupational and Environmental Dermatology.

Background: Urticaria is a disorder affecting skin and mucosal tissues characterized by the occurrence of wheals, angioedema or both, the latter defining the urticaria-angioedema syndrome. It is estimated that 12-22% of the general population has suffered at least one subtype of urticaria during life, but only a small percentage (estimated at 7.6-16%) has acute urticaria, because it is usually self-limited and resolves spontaneously without requiring medical attention.

IgE allergy diagnostics and other relevant tests in allergy, a World Allergy Organization position paper.

Currently, testing for immunoglobulin E (IgE) sensitization is the cornerstone of diagnostic evaluation in suspected allergic conditions. This review provides a thorough and updated critical appraisal of the most frequently used diagnostic tests, both and . It discusses skin tests, challenges, and serological and cellular tests, and provides an overview of indications, advantages and disadvantages of each in conditions such as respiratory, food, venom, drug, and occupational allergy.

Neuronal contact guidance and YAP signaling on ultra-small nanogratings.

Contact interaction of neuronal cells with extracellular nanometric features can be exploited to investigate and modulate cellular responses. By exploiting nanogratings (NGs) with linewidth from 500 nm down to 100 nm, we here study neurite contact guidance along ultra-small directional topographies. The impact of NG lateral dimension on the neuronal morphotype, neurite alignment, focal adhesion (FA) development and YAP activation is investigated in nerve growth factor (NGF)-differentiating PC12 cells and in primary hippocampal neurons, by confocal and live-cell total internal reflection fluorescence (TIRF) microscopy, and at molecular level.

Galactose α-1,3-galactose phenotypes: Lessons from various patient populations.

Objective: To review published studies on galactose α-1,3-galactose (α-gal), a carbohydrate epitope found on proteins and lipids in nonprimate mammals and present in foods (particularly organ or fat-rich red meat) and medications, where it causes delayed-onset and immediate-onset anaphylaxis.

Data Sources: A literature search for the terms galactose α-1,3-galactose and α-gal using PubMed and Embase was performed.

Study Selections: Studies on α-gal were included in this review.

The Characteristics of Severe Chronic Upper-Airway Disease (SCUAD) in Patients with Allergic Rhinitis: A Real-Life Multicenter Cross-Sectional Italian Study.

Background: There are few studies regarding severe chronic upper-airway disease (SCUAD) that represents an important socioeconomic problem for the treatment of rhinitis and associated comorbidities, particularly asthma.

Objectives: The aim of our study is to evaluate the prevalence of this pathology in patients with allergic rhinitis (AR) in real life, to phenotype allergic patients with SCUAD, and to identify which factors are related to the severity of the disease.

Methods: We studied 113 patients with uncontrolled AR despite optimal adherence to therapy according to the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines in a multicenter Italian study, analyzing comorbidity, use of additional drugs, not scheduled visits, and the number of emergency room admissions.

Music reduces pain perception in healthy newborns: A comparison between different music tracks and recoded heartbeat.

Objectives: To assess the effect of 3 musical interventions, as compared to no music, on the physiological response of healthy newborns undergoing painful medical procedures (Guthrie test and/or intramuscular antibiotic injections).

Methods: Prospective study of 80 full-term newborns, aged 1 to 3 days, randomly allocated to exposure to Mozart's Sonata for two pianos K.448, Beethoven's Moonlight Sonata, heartbeat sound recordings (70 bpm) or no music.

[New in vitro allergological diagnostic tool and its application in professional disease.].

Molecular diagnostic is a new therapeutic approach that - allows to valuate sensitization towards a single molecule in a allergenic source and to obtain relevant information on clinical features: sensitization towards molecules as alfa amylase of wheat or lipocalins of pets, Alt a 1 of alternaria spores and Hev b 6 of latex correlates with the risk to develop asthma - has a greater sensitivity in the serum IgE identification than the whole source.

Critical aspects in dog allergen immunotherapy (DAI). May Component Resolved Diagnosis (CRD) play a role in predicting the efficacy?

We hypothesize that a pivotal condition determining the efficacy of dog allergen immunotherapy (DAI) might be the mono-sensitization to dog lipocalins (Can f 1-2) in individuals not directly or indirectly exposed to other furry animals. In fact, the concomitant sensitization to lipocalins and/or albumins, especially in those patients directly exposed to furry animals, may potentially stimulate patient's airways by inducing persistent inflammation and, thus, clinical symptoms. In these conditions, it is likely that DAI alone could be inadequate to reduce airway inflammation mediated by inhalation of dog allergens in patients with simultaneous exposure to other furry animals.

Chronic Urticaria Patient Perspective (CUPP): The First Validated Tool for Assessing Quality of Life in Clinical Practice.

Background: There is a need for validated tools to assess health-related quality of life (HRQoL) in routine clinical practice.

Objective: The aim of this study was to validate the Chronic Urticaria Patient Perspective (CUPP) for assessment of patients with chronic urticaria (CU) in clinical practice.

Methods: A provisional CUPP was developed from candidate items identified by following an iterative process in a retrospective analysis of 249 Chronic Urticaria Quality of Life Questionnaire questionnaires.

Which immunotherapy product is better for patients allergic to Polistes venom? A laboratory and clinical study.

Background: Venom immunotherapy (VIT) is highly effective in preventing allergic reactions to insect stings, but the appropriate venom must be used to achieve clinical protection. In patients with multiple positive results to venoms, molecular allergy diagnostics or CAP-inhibition may identify the causative venom. Concerning allergy to venom from Polistes spp.

Is allergic sensitization relevant in severe asthma? Which allergens may be culprit?

Severe asthma is a major health concern. The allergic (IgE-mediated) form of asthma is well known from a pathogenic viewpoint. We searched the available literature to identify which allergens are most frequently associated with severe, refractory or life threatening asthma.

Potential of molecular based diagnostics and its impact on allergen immunotherapy.

Molecular based in vitro technologies greatly changed the diagnostic approaches in allergy. At present, sensitization profiles can be dissected according to IgE subsets, which are specific for genuine or cross-reacting components and potentially dangerous or virtually harmless components. The identification of IgE in components with specific characteristics has a direct impact on the accuracy of the diagnosis (indeed, it is possible at present to not only identify the allergen derived from a given allergen source but also the family of molecules to which the patient is sensitized), on the prognosis of the patient's allergy, and on the prevention activities to be implemented.

Appropriateness in allergic respiratory diseases health care in Italy: definitions and organizational aspects.

In a historical period in which sustainability of the National Health Service is mandatory because of the international economical situation, the limited available resources at national level and the tendency of passing from a "population medicine" model towards the concept of "individualized medicine", the debate on appropriateness of medical and surgical procedures is of central importance. The choosing wisely campaign, started in United States in 2012 and then spread all over the world, tries to summarize which are the most inappropriate procedures for each medical and surgical speciality; as far as allergic respiratory diseases, the most relevant Italian societies and the American Academy defined the allergological procedures with the highest probability of inappropriateness. In Italy, a recent decree of the Ministry of Health defined a list of more than 200 procedures that will be considered as inappropriate in certain conditions; many of these procedures concern allergology, including allergic respiratory diseases.

Comparing the ability of molecular diagnosis and CAP-inhibition in identifying the really causative venom in patients with positive tests to Vespula and Polistes species.

Background: Cross-reactivity among Hymenoptera venoms is an important issue when prescribing venom immunotherapy (VIT). Using all venoms eliciting a positive response results in treatment excess and unjustified cost increase. The first in vitro method that helped to identify the really causative venom was RAST-inhibition, but in latest years also molecular allergy (MA) diagnostics, that detects specific sIgE to single venom allergens, was introduced.

How far from correct is the use of adrenaline auto-injectors? A survey in Italian patients.

Self-administered adrenaline through an auto-injector is the main out-of-hospital treatment for anaphylaxis, and patients should be trained to promptly and correctly use the device. The aim of the study was to verify the proper use of the device and the correct drug administration, and to identify possible misuse by patients. In seven Italian Allergy clinics, patients who were previously provided with self-injectable adrenaline were recruited at the follow-up visit required for the renewal of their prescription.

Association between a low IgE response to Phl p 5 and absence of asthma in patients with grass pollen allergy.

Background: The introduction of component-resolved diagnosis was a great advance in diagnosis of allergy. In particular, molecular allergy techniques allowed investigation of the association between given molecular profiles and clinical expression of allergy. We evaluated the possible correlation between the level of specific IgE (sIgE) to single components of Phleum pratense and clinical issues such as the severity of allergic rhinitis (AR) and the presence or absence of asthma.
