Milk Allergy is Frequent in Patients with Chronic Sinusitis and Nasal Polyposis

Abstract

In contrast to previous studies in other countries presenting a food allergy incidence of ∼75% in patients with nasal polyposis, we could not show such a high incidence. In the group with chronic polyposis 14% of the patients were positive for milk allergy compared with none of the tested healthy subjects, resulting in a strong statistical significance. Therefore, we conclude that cow's milk but not wheat allergy might be a relevant pathogenetic entity in chronic nasal polyps.
