Abstract

SHAHAR and colleagues, Institute of Allergy, Clinical Immunology, and AIDS, Rambam Medical Center, Haifa, Israel, ed_shahar@rambam.health.gov.il, have studied the effect of vitamin E supplementation on seasonal allergic rhinitis (hay fever).

Background

Evidence from basic science studies suggests that vitamin E may reduce allergic immune responses. However, only a few clinical studies of the effect of vitamin E on allergic conditions have been performed in patients with eczema and asthma, and none have been performed in patients with allergic rhinitis. The aim of this study was to determine the effect of high-dose vitamin E supplementation in combination with standard treatment on the symptoms of seasonal allergic rhinitis.

Methodology

In this double-blinded, placebo-controlled, randomized study, 112 patients with documented hay fever received either vitamin E (800 mg/d) or placebo in addition to their regular treatment during the pollen season. Patients recorded their daily nasal and eye symptoms and their daily need for other medications.

Results

Nasal symptom scores were lower in patients who received vitamin E supplementation during the hay fever season. However, there was no reduction in the percentage of days with serious symptoms or in the percentage of days that medications were used to control allergic symptoms during the pollen season. No effect was observed on ocular symptoms.

Conclusion

Vitamin E supplementation may be a valuable addition to the treatment of patients with hay fever. However, further clinical and basic science studies are needed.
