Abstract

Patients with peach allergy due to nsLTP sensitization constitute a heterogeneous group in terms of sensitization profile and severity. This could be due to the presence of additional allergies to pollens. The aim of this study was to analyse the clinical characteristics, sensitization profile and severity of reactions in peach-allergic patients sensitized to nsLTP from two Mediterranean areas with different pollen exposure. Patients with diagnosis of LTP allergy from the Allergy Unit of Hospital Regional Universitario de Malaga (HRUM) and Hospital Clinic de Barcelona (HCB) were prospectively included and classified into two groups; (a) LTP-monoallergic: those that presented reaction only with peach and (b) LTP-Allergy: those that presented reaction with peach and at least another plant-food containing LTP. A total of 252 patients were included, 235 (93.2%) had LTP-syndrome and 17 (6.8%) were LTP-monoallergic. We found a higher percentage of anaphylaxis and delayed onset of symptoms in the LTP-monoallergic group (P = .02 and P = .04, respectively). Moreover, anaphylaxis was less frequent in patients with profilin sensitization (P = .03). The comparison of patients' data from HRUM with data from HCB showed differences in sensiti...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.
