Insights
Vitamin D deficiency is common in Egyptian children with allergic rhinitis (AR). Lower vitamin D levels correlate with increased AR severity and symptoms.
Area of Science:
- Pediatric Allergy and Immunology
- Nutritional Biochemistry
- Epidemiology
Background:
- Allergic rhinitis (AR) is a prevalent condition in children.
- Vitamin D plays a crucial role in immune system regulation.
- The association between vitamin D status and AR severity requires further investigation, particularly in diverse ethnic cohorts.
Purpose of the Study:
- To determine serum vitamin D levels in Egyptian children diagnosed with allergic rhinitis.
- To investigate the relationship between vitamin D status and the severity of allergic rhinitis.
- To explore correlations between vitamin D levels, clinical symptoms, and immunoglobulin E in pediatric AR.
Main Methods:
- Cross-sectional study involving 120 children with AR and 100 healthy controls.
- Measurement of serum 25(OH)D and 1,25(OH)2D levels in all participants.
- Statistical analysis to compare vitamin D levels and assess associations with AR severity, symptom scores, and total IgE.
Main Results:
- Children with AR exhibited significantly lower serum calcium, 25(OH)D, and 1,25(OH)2D levels compared to healthy controls.
- Patients with moderate/severe AR had significantly lower mean 25-OHD3 levels than those with mild AR.
- Negative correlations were observed between 25(OH)D levels and total nasal symptom score (r = -0.62) and total IgE levels (r = -0.27) in the AR group.
Conclusions:
- Vitamin D deficiency is prevalent in Egyptian children suffering from allergic rhinitis.
- Lower vitamin D levels are significantly associated with increased allergic rhinitis severity in this pediatric cohort.
- Findings suggest a potential role for vitamin D supplementation in managing allergic rhinitis in children.
Abstract:
Objective: This study aimed to assess the serum levels of vitamin D in an Egyptian cohort of children with allergic rhinitis (AR) and to evaluate any correlation of vitamin D status with the disease severity. Patient and methods: One hundred twenty children with AR and 100 healthy children were included in our study. We studied the serum levels of vitamin D 25(OH)D and 1,25(OH)2D in all participants. The associations between vitamin D levels and clinical characteristics of AR were examined. Results: In AR group, the serum levels of calcium, (25(OH)D and 1,25(OH)2D levels were significantly lower (p < .0001, p < .001, and p < .0001, respectively) in AR children than in controls. Furthermore, the mean 25-OHD3 levels in patients with moderate/severe AR were significantly lower than those with mild AR (p < .001). We found significant negative correlations between mean 25(OH)D levels and total nasal symptom score (r = -.62, p = .002) and total immunoglobulin E levels (r = -.27, p = .013) in AR group. Conclusions: Vitamin D deficiency is a frequent finding among Egyptian children with AR when compared to the healthy group. A significant inverse association was observed between vitamin D levels and AR disease severity.
