Introduction: To assess the safety and efficacy of an oral immunotherapy regimen in patients with allergy to lipid transfer proteins (LTPs).

Materials And Methods: Prospective study of 24 patients allergic to LTP with positive skin test and a history of anaphylaxis. All patients underwent a desensitization protocol with commercial peach juice.

Background: Whether the observed clinical pattern of non-specific lipid transfer protein (nsLTP)-mediated food allergies is attributable to a primary sensitization by Pru p 3 from peach and subsequent cross-reactivity with Rosaceae- and non-Rosaceae-derived foods expressing homologous allergens is still unclear.

Objective: To investigate the allergenic properties of nsLTPs from Rosaceae and non-Rosaceae foods.

Methods: In peach-, cherry- or hazelnut-allergic patients, prevalence of sensitization, IgE-binding capacity, cross-reactivity and allergenic potency of Pru p 3 was compared with Pru av 3 (cherry) and Cor a 8 (hazelnut).

Background: A considerable number of pollen-allergic patients develops allergy to plant foods, which has been attributed to cross-reactivity between food and pollen allergens. The aim of this study was to analyze the differences among pollen-allergic patients with and without plant food allergy.

Methods: Eight hundred and six patients were recruited from 8 different hospitals.

Background: Plant food allergy in the Mediterranean area is mainly caused by non-specific lipid transfer proteins (nsLTP). The aim of this study was to characterize peanut nsLTP in comparison with peach nsLTP, Pru p 3, and assess its importance in peanut allergy.

Methods: Peanut-allergic patients from Spain (n=32) were included on the basis of a positive case history and either a positive skin prick test or specific IgE to peanut.

Alternaria alternata (AA) is an important mould in respiratory allergic diseases. The objective is to determine the prevalence of AA sensitization in respiratory allergic patients and to examine the annual variation of Alternaria spores. 824 patients between 5 and 65 years old with allergic rhinitis and /or asthma were enrolled.

Total tear IgE has been considered to play an important role in allergic conjunctivitis, and measurement has been considered useful for diagnosis. The aim of this study was to ascertain whether Lacrytest(®), a new commercialised method to detect IgE levels in lacrimal fluid, could constitute a screening test for the diagnosis of allergic conjunctivitis. This was a cross-sectional study.

Allergen extracts have been used for diagnosis and treatment of allergy for around 100 years. During the second half of 20th century, the notion increasingly gained foothold that accurate standardization of such extracts is of great importance for improvement of their quality. As a consequence, manufacturers have implemented extensive protocols for standardization and quality control.

Article Synopsis
  • Human seminal plasma (HSP) allergy is rare but can lead to severe reactions, often appearing during or after the first sexual encounter, with prostate-specific antigen (PSA) being identified as a key allergen.
  • Researchers investigated potential IgE cross-reactivity between allergens in dog epithelium and HSP in patients with dog allergies, using various testing methods.
  • The study found that 24% of patients with dog allergies had IgE that recognized PSA, and preincubation with dog dander completely inhibited IgE-binding, confirming a cross-reactivity between dog allergens and PSA.

Background: Hazelnuts are a common cause of food allergic reactions. Most hazelnut allergic individuals in central and northern Europe are sensitized to Cor a 1, a member of the PR-10 protein family, while the lipid transfer protein Cor a 8 acts as a major allergen in the south of Europe. Other allergens, including profilin and seed storage proteins, may be important in subgroups of patients.

Background: IgE sensitisation to non-specific lipid transfer proteins (nsLTP), e.g., Pru p 3 the major allergen from peach and most important allergenic LTP, is strongly associated with severe symptoms in food allergic patients.

Background: Birch pollen-specific immunotherapy (SIT) decreases allergy to foods containing birch pollen-homologous allergens. Cross-reactivity was also observed between plane tree pollen and some vegetable foods.

Objective: The aim of this study was to evaluate the outgrowing of food allergy by patients suffering from vegetable food allergy associated with plane tree pollinosis (rhinoconjunctivitis and/or asthma) during plane tree pollen SIT.

Background: An association between plane tree pollen allergy and plant food allergy has been described, but the cross-reacting allergens have not yet been identified. The aim of this study was the identification of homologous non-specific lipid-transfer proteins (nsLTPs) in plane pollen, and to investigate its immunological relationship with the peach LTP, Pru p 3.

Methods: Three different patient groups were recruited in Spain: 22 plane pollen-allergic patients without food allergy (A), 36 plane pollen-allergic patients with peach allergy (B) and 10 peach-allergic patients without plane pollen allergy (C).

Background: Plane tree pollen allergy is a clinical disorder affecting human population in cities of Europe, North America, South Africa, and Australia.

Objective: To compare IgE-reactivity of the natural and recombinant forms of two major plane allergens, Pla a 1 and Pla a 2, with the reactivity of Platanus acerifolia pollen extract.

Methods: Forty-seven patients with P.

Background: Lipid transfer proteins (LTPs) are relevant allergens in certain plants. The role of the LTP of Hevea brasiliensis in the latex-fruit syndrome is widely unknown.

Objective: To study IgE reactivity with recombinant Hevea LTP in sera of fruit-allergic adults with and without natural rubber latex (NRL) allergy.

Purpose Of Review: Food allergy may be life threatening and its management continues to consist of avoiding relevant allergens and, in the case of accidental ingestion, initiation of appropriate emergency therapy. The aim of this article is to describe current treatment approaches and discuss attempts to use specific immunotherapy for food-allergy treatment.

Recent Findings: A recent study reports the use of sublingual immunotherapy for hazelnut food allergy in hazelnut-allergic patients.

Human seminal plasma allergy in women is an uncommon phenomenon. A great variety of reactions ranging from local swelling to generalized systemic reactions have been described, and local symptoms have often been misdiagnosed as chronic vulvovaginitis. Sperm barriers, such as condoms, are the most widely advocated method for avoiding these reactions; however this is not acceptable to couples who wish to have children.

Although furry animals are known sources of respiratory allergy, scaly animals are assumed not to be allergenic. Exotic animals such as iguanas are becoming increasingly common pets. Nevertheless, these animals are not suspected to be allergenic.

Background: Food allergy to cherry occurs throughout Europe, typically with restricted oral reactions in the central and northern parts but with frequent systemic reactions in the Mediterranean region. Previous studies have demonstrated insufficient sensitivity of commercially available cherry extract reagents in the diagnosis of cherry allergy.

Objective: To assess the diagnostic performance of specific IgE tests based on recombinant cherry allergens in comparison with an extract-based assay and to skin prick test (SPT).
