Insights
Children with vernal keratoconjunctivitis (VKC) have lower serum vitamin D levels and higher body mass index (BMI) compared to healthy children. This study highlights a potential link between vitamin D deficiency, elevated BMI, and VKC in pediatric patients.
Area of Science:
- Ophthalmology
- Pediatrics
- Endocrinology
Background:
- Vernal keratoconjunctivitis (VKC) is a severe allergic eye disease affecting children.
- Vitamin D deficiency and obesity are increasingly recognized as global health issues with potential systemic implications.
- The relationship between VKC, vitamin D status, and body mass index (BMI) requires further investigation.
Purpose of the Study:
- To investigate the association between serum 25-hydroxyvitamin D [25(OH)D3] levels and body mass index (BMI) in children diagnosed with vernal keratoconjunctivitis (VKC).
Main Methods:
- A comparative study involving 46 children with VKC and 40 healthy, non-atopic children.
- Serum 25(OH)D3 levels and BMI values were measured and statistically analyzed between the two groups.
Main Results:
- Children with VKC exhibited significantly lower mean serum vitamin D levels (14.06±5.02 ng/mL) compared to healthy controls (19.01±5.66 ng/mL).
- The VKC group presented with a significantly higher mean BMI (17.1±2.5 kg/m² ) than the control group (16.5±2.3 kg/m²).
- A significant negative correlation was found between serum vitamin D levels and BMI in the study population (Spearman's rho=-0.275; p=0.01).
Conclusions:
- Children suffering from VKC demonstrate lower serum vitamin D concentrations and elevated BMI compared to their healthy peers.
- These findings suggest a potential role for vitamin D deficiency and higher BMI in the pathophysiology or exacerbation of VKC in children.
- Further research is warranted to explore the clinical implications and potential therapeutic strategies targeting vitamin D and BMI in VKC management.
Objectives:
The purpose of this study was to evaluate the body mass index (BMI) value and serum 25-hydroxyvitamin D [25(OH)D3] level in children with vernal keratoconjunctivitis (VKC).
Methods:
A total of 40 healthy, non-atopic children (control group) and 46 children with VKC (study group) were included in the study. The serum vitamin D [25(OH)D3] levels and BMI values were measured and compared between the 2 groups.
Results:
The mean vitamin D level measured in the healthy children (mean: 19.01±5.66 ng/mL, range: 9-33.09 ng/mL) was significantly different from the mean vitamin D level in the VKC-affected children (mean: 14.06±5.02 ng/mL, range 4.37-31 ng/mL) (p<0.001). The mean BMI in the VKC group (17.1±2.5 kg/m2) was significantly higher than the mean BMI of the healthy children (mean: 16.5±2.3 kg/m2; p=0.046). A negative correlation (Spearman's rho=-0.275; p=0.01) was observed between the vitamin D level and the BMI value.
Conclusion:
The results indicated that children with VKC had a lower serum vitamin D level and a higher BMI value compared with healthy, age- and sex-matched children.
