Background: Foods containing flaxseed proteins rich in polyunsaturated fatty acids are new on the market. Objectives: In a population of patients attending the allergology department, we evaluated the frequency of sensitization to flaxseed, characterized allergens and looked for modifications related to industrial processing. Methods: Natural, heated and extruded flaxseeds were tested using prick-in-prick tests (PIP […]

Background: Olive pollen sensitization is surprisingly frequent in Milan, an area that is virtually both olive- and ash-free.Objective:To establish the prevalence of olive pollen sensitization north of Milan, and to investigate the allergens involved.Methods: 300 pollenallergic patients living in this area were randomly selected. Based on SPT-results, olive pollen reactors were classified as multi-sensitized, oligo-sensitized, […]
The standardization of allergen extracts is of primary relevance to the clinical efficacy. Biological standardization procedures are widely used in the commercial production of vaccines. We tested, in grass-allergic patients, the potency of three different grass extracts for sublingual immunotherapy by means of skin prick tests. Specific IgE against Phl p 1, 2, 4, 5, […]
Background: Studies suggest a link between vitamin D deficiency and development of asthma and allergic diseases. Aim: To determine a) the association between vitamin D and asthma among children , b) difference in level of vitamin D in asthmatic children and control, and c) effect of vitamin D on atopy markers. Setting: Case-control study done, […]
Background: The clinical efficacy of Monophosphoryl lipid A-adjuvanted immunotherapy (MPLA-SCIT) is ascertained, but there are no data on its possible longlasting effect. We assessed in a real-life setting the persistence of the clinical effect five years after discontinuation. Methods: Patients with parietaria-induced respiratory allergy and fulfilling the criteria for immunotherapy prescription were evaluated at baseline, […]
Knuckle pads is a syndrome characterized by the presence of multiple nodules located on the extensor side of the interphalangeal or metacarpophalangeal joints. Several conditions can be confused with Knuckle pads. We describe a case of a 47-years-old man who developed multiple bilateral roundish nodules located in the skin over the dorsal and lateral interphalangeal […]

Background: Lipid transfer protein (LTP) is a widely cross-reacting plant pan-allergen, and sensitized patients may react to many foods. Although peanut allergy is frequently reported by LTP-allergic patients, the evidence of the presence of an allergen homologous to LTP in peanuts is limited. Objective: To assess the prevalence of peanut allergy in patients sensitized to […]
Background: Natural rubber latex allergy is a condition at high risk of anaphylaxis during surgery. However, latex contains several protein allergens and not all of them may show the same clinical relevance. Objective: To investigate the clinical relevance of Hev b 8, the natural rubber latex profilin. Methods: Seven patients without a clinical history of […]

Background: Different in vivo methods are used to quantify the amount of allergens in products for skin prick testing. It is unclear how this impacts on the correct diagnosis of allergies. Aim of the Study: We compared the allergenic potency of three commercial extracts for skin prick testing and evaluated batch-to-batch differences within each product. […]
Background: Subjects with drug hypersensitivity are sometimes simultaneously reactive to several drugs. This nosological entity is defined as multiple drug hypersensivity (MDH). Urticaria and angioedema are the commonest clinical manifestations of hypersensitivity drug reactions (HDR). These clinical signs are also pathognomonic of chronic idiopathic urticaria (CIU), whose pathogenetic mechanisms are still largely unknown. The diagnostic […]
