Study Title:

Food Sensitization in Medically Resistant Chronic Rhinosinusitis with or without Nasal Polyposis.

Study Abstract

BACKGROUND:

Nasal polyposis is a common nasal mass with unknown etiology. It has been assumed that allergy predisposes to polyp formation. Our objective was to compare the prevalence of food sensitization in medically resistant chronic rhinosinusitis patients with or without nasal polyposis.
METHODS:

One hundred and fifty-five patients who fulfilled the inclusion and exclusion criteria were incorporated into this study. The results of their total serum IgE and food-specific IgE levels were examined.
RESULTS:

The average age was 33 years (± 13) with 96 males and 59 females. The percentage of patients in each group that had a positive result for at least one tested allergen was 84% (88 patients in the sinusitis without polyposis group and 42 patients in nasal polyposis group). Patients without nasal polyposis reacted to an average of 4.6 foodstuffs, whereas patients with nasal polyposis reacted to 4.1. Egg white, sheefish and cherry were the most common type of sensitized food. There were no significant differences in the prevalence, type, number of positive food allergens and class level between the two groups.
CONCLUSIONS:

Food sensitization is common in medically resistant chronic rhinosinusitis. Since food sensitization prevalence, type and severity do not significantly differ between the two groups studied, food atopy is unlikely to be a major factor in nasal polyposis pathogenesis.
