Latex-fruit syndrome in Italian children and adolescents with natural rubber latex allergy.

Approximately 30-50 percent of individuals with natural rubber latex (NRL) allergy show an associated hypersensitivity to particular plant-derived foods, which has been defined "latex-fruit syndrome" (LFS). In our population of 22 patients with IgE-mediated NRL allergy we found a relevant prevalence (36 percent) of LFS, which resulted significantly higher in the group of patients with more severe clinical manifestations of NRL allergy than in patients with contact symptoms due to NRL (78 percent vs 8 percent; less than 0.005).
