Background: There is some evidence suggesting that factors other than autoantibodies to FceRI or IgE and histamine released from mast cells may play a role in skin autoreactivity that characterizes many patients with chronic urticaria (CU) and, possibly, in the pathogenesis of this disease. Objective: The effect of antihistamine treatment on autologous plasma skin test (APST) […]

Introduction: High-resolution computed tomography (HRCT) is a widespread medical imaging method for the study of thoracic diseases. In asthma it is very useful particularly when it is difficult to achieve an effective control of disease, and in severe deterioration. Aim: It was intended to evaluate the imaging changes by HRCT in asthmatic patients and to […]
Aim: to assess the accuracy and safety of a ready-to-use atopy patch test (HDM-Diallertest ®, DBV Technologies, Paris) in the diagnosis of sensitization to house-dust mite (HDM) allergens in children with or without atopic dermatitis. Patients and methods: prospective analysis of a systematic allergic work-up was carried out in 47 children, age 57.4+42 months (mean […]
Background: Carboxymethylcellulose (CMC) is used extensively in the pharmaceutical and food industries on account of its various properties. Anaphylactic reactions are rare. It has been reported principally after intra-articular infiltration of sustained-release corticosteroids containing CMC and, very rarely, after barium enema. Methods: A case of pre-lethal anaphylactic shock after barium enema was studied by prick-test, […]
The efficacy and safety of monomeric allergoid (Lofarma, Milan) have been demonstrated in adults but very few studies have examined it in children. This study therefore investigated the efficacy and safety of this sublingual immunotherapy (SLIT) at the dosage of 1000 AU five times a week without any up-dosing. Forty allergic children(17 M and 23 […]
The definition of reference normal values for urinary LTE4 still represents an open question. Aim: to assess the influence of gender and age on urinary LTE4 levels in normal individuals. Methods: after their informed consent, urinary LTE4 was measured in 124 well matched, non smoker, non atopic subjects (mean age 49.5 y±20.1 sd; range 4-85 […]
Background: Allergy to crustacean shellfish is one of the most common IgE-mediated food allergies, and tropomyosin has been identified as the major allergen. However, not all subjects affected by this allergy are IgE-positive to tropomyosin. Aims: To evaluate whether sera of patients with shrimp allergy but negative for tropomyosin react to other allergen(s); and to […]
Objective: Omalizumab (OM), an innovative biological treatment for difficult asthma with perennial sensitisations, is an humanized monoclonal anti-IgE antibody that binds free circulating IgE; inhibits mast cell and basophil activation by combining free IgE, leads to IgE receptor down-regulation, thus blocking the inflammatory cascade. AIM of the study was to assess real-world cost-utility of add-on […]
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 […]
Background: The allergenic profile of patients hypersensitive to pollen pan-allergens, profilin and polcalcin, has received little attention so far. Objective: To detect whether hypersensitivity to profilin and polcalcin follows sensitization to specific allergen sources or represents a primary phenomenon, and to examine the sensitization profiles of patients hypersensitive to pollen pan-allergens. Methods: IgE reactivity to […]
