Oral allergy syndrome (OAS) is defined as the symptoms of IgE-mediated immediate allergy localized in the oral mucosa, and the characteristics depend on the lability of the antigen. Another term used for this syndrome is pollen-food allergy (PFS); the patient is sensitized with pollen via the airways and exhibits an allergic reaction to food antigen with a structural similarity to the pollen (c...

Introduction: Allergy to nonspecific lipid transfer protein (nsLTP) is the main cause of plant-food allergy in Spain. nsLTPs are widely distributed plant kingdom and have high cross-reactivity but extremely variable clinical expression. Little known about natural evolution this allergy, which complicates management. The objective study was assess development new foods nsLTP-sensitized patients ...

BACKGROUND AND OBJECTIVES The number of patients allergic to latex has increased significantly. It is crucial to recognize the cases in order to prevent and apply adequate treatment. The objective of this study was to evaluate the prevalence of allergy to latex in meningomyelocele patients. MATERIALS AND METHODS A retrospective evaluation of medical records of patients with meningomyelocele d...

According to literature, approximately 20%-70% of patients sensitized to pollen allergens experience oral allergy syndrome (OAS) symptoms after eating raw fruits and vegetables. There is no standard treatment established for OAS except avoiding implicated food. However, in patients with airborne pollen allergy treated with specific immunotherapy (SIT), an improvement of OAS symptoms has been re...

Hereditary fructose intolerance (HFI) symptoms develop at first introduction of fruit during weaning. We report on an infant with suspected HFI who presented with repeated episodes of vomiting and hypotension after ingestion of fruit-containing meals. The first episode occurred at age 4 months. Despite negative genetic testing for HFI, strict avoidance of fruit ingestion resulted in lack of rec...

Background A considerable number of pollen-allergic patients develops allergy to plant foods, which has been attributed to crossreactivity between food and pollen allergens belongs to PR-10 proteins. The majority of these patients refuse from take the foods containing PR-10 explaining bad taste or sense of itch in the mouth syndrome of oral allergy (SOA). It is assumed that the primary is sensi...

Case Report A 16-year-old boy presents to the allergy clinic with complaints of perioral itching and tingling after handling apples at his father’s fruit stall. He had experienced such symptoms on previous occasions, but this time he has developed mild lip swelling and tongue itching, as well. He has a history of seasonal allergic rhinitis that is controlled by nasal steroid spray. His father i...

Food allergy affects many young children and tree nut allergy is accountable for a large number of severe, life-threatening anaphylactic reactions. Cross-reactivity can occur not only with foods that are in the same biological family but also between certain fruits or vegetables and latex (latex-fruit syndrome). We present the case of a previous healthy 5-year-old girl referred to Pediatric/All...

The objectives of this study are 1) To review the published data and document the current knowledge on allergic manifestations to the fruit mango 2) To highlight the two distinct clinical presentations of hypersensitivity reactions caused by mango 3) To discuss the role of cross-reactivity 4) To increase awareness of potentially life threatening complications that can be caused by allergy to ma...

Background Actually, there are few reports of cross-reactivity between cassava and latex in the syndrome latex-fruit. Of allergens in the latex are identified particularly relevant to this case, recall some of them: Hev b 6.02, major allergen, Hev b 1, structural homology to papain, and Hev b 5, which could be responsible for the cross reactivity between latex and cassava by their structural si...
