Total IgE level in respiratory allergy: study of patients at high risk for helminthic infection.

Objective: Eosinophilia and increased serum IgE levels are indicators of atopy; however, other factors can also play a key role, such as intestinal parasitic infections. This study assesses the relationship between total serum IgE, eosinophil count, and anti-Ascaris IgE in individuals with asthma and/or allergic rhinitis.

Methods: A cross-sectional study was carried out in adolescents with asthma and/or allergic rhinitis.
