OBJECTIVE: Study of the association between immunoglobulin-G (IgG) subclass deficiency and nasal polyposis.
MATERIAL AND METHODS: Longitudinal study (5 years) in a prospective cohort of 161 nasal polyposis patients. Analysis of the association between humoral immunodeficiency, rhinologic symptoms, endoscopy score and prescribed doses of local and systemic corticosteroids.
RESULTS: The prevalence of IgG subclass deficiency was 13.7% (22/161). One patient was diagnosed with common variable immunodeficiency (CVID). No significant differences were observed between the groups with and without pre-treatment deficiency for symptom severity, endoscopic score or local or systemic corticosteroid regimens at baseline or during the 5 years, following initiation of medical and surgical treatment. Only the Lund-Mackay CT score was significantly higher in the pre-treatment deficiency group.
CONCLUSION: There was no correlation between the presence of humoral deficiency and either symptom evolution after medical and surgical treatment or the dose of corticosteroids needed to control disease. Thus, a link between IgG subclass deficiency and nasal polyposis seems unlikely.
