Abstract
Background: Allergic rhinitis is a frequent disorder during pregnancy, while in children it is triggered by significantly lower serum vitamin E level. This research aimed to investigate whether serum vitamin E level exhibited clinical significance in pregnant women with allergic rhinitis.
Methods: In this study, 37 pregnant women with allergic rhinitis and 35 healthy pregnant women were recruited. Allergic rhinitis severity was analyzed by the Total Nasal Symptom Score (TNSS) questionnaire. Blood samples were collected to evaluate serum vitamin E, interleukin (IL) and total IgE levels.
Results: In pregnant women with allergic rhinitis, serum level of vitamin E was significantly lower than in healthy pregnant women. Serum vitamin E level in pregnant women with allergic rhinitis showed negative correlation with TNSS, IL-13, IL-4, and total IgE levels.
Conclusion: In conclusion, this research has demonstrated that pregnant women with allergic rhinitis showed significantly lower serum level of vitamin E. The decreased vitamin E showed correlation with the pathogenesis of allergic rhinitis in pregnant women.
