Abstract |
Objective |
Study of the association between immunoglobulin-G (IgG) subclass deficiency and nasal polyposis.
Material and methods |
Longitudinal study (5years) 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 5years, 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.
