Abstract
Allergic rhinitis is a common and chronic immunoglobulin E-mediated inflammation of nasal mucosa induced after allergen exposure. Allergic rhinitis is a global health problem that causes major illness and affects patient's social life, sleep, school and work performance. Various studies have implicated the association between low serum vitamin D levels and allergic diseases. Active form of Vitamin D3 has been shown to have immunoregulatory effect on both innate and adaptive immunity, which can significantly affect the outcome of allergic responses in allergic rhinitis. The study aims to evaluate effectiveness of Oral Vitamin D3 supplementation as an adjunct to standard therapy, in the management of allergic rhinitis. The present study is a prospective study in which 80 subjects were recruited and were randomly divided into two groups. The study group received oral vitamin D3 (60,000 IU) along with intranasal steroid spray while control group received only intranasal steroid spray for 4 weeks. The response in both the groups was compared by evaluating total nasal symptom score (TNSS). Subjects of allergic rhinitis showed deficiency in vitamin D indicated by mean serum vitamin D levels of 15 ± 2.42 ng/ml in the study group and 14.72 ± 2.64 ng/ml in the control group. The pre treatment mean TNSS score was 10.45 ± 3.1 in the study group and 11.43 ± 2.35 in the control group. The post treatment mean TNSS score was 2.1 ± 0.21 in the study group and 3.85 ± 0.76 in the control group. A significant reduction in symptoms score was observed after 4 weeks of oral vitamin D3 supplementation. The difference between two groups was found to be statistically significant (p value < 0.05).
