Insights
Children with urinary tract infections (UTIs) have significantly lower vitamin D levels. Vitamin D screening and supplementation may help prevent UTIs and improve outcomes in pediatric patients.
Area of Science:
- Pediatrics
- Infectious Diseases
- Endocrinology
Background:
- Urinary tract infections (UTIs) are common in children.
- Vitamin D deficiency is linked to various infections, including UTIs.
- This study investigated the association between serum vitamin D and UTIs in pediatric patients.
Purpose of the Study:
- To evaluate the association between serum vitamin D levels and UTIs in children.
- To compare vitamin D levels in children with and without UTIs.
Main Methods:
- A case-control study involving 120 children (aged 2-18 years) at Amir Kola Children's Hospital.
- 60 children with UTIs (cases) and 60 healthy children (controls).
- Serum vitamin D levels measured by ELISA; statistical analysis using SPSS v.26.
Main Results:
- Children with UTIs had significantly lower mean serum vitamin D levels (17.70±8.35 ng/mL) compared to controls (37.91±12.18 ng/mL) (P<0.001).
- Pyelonephritis was associated with severe vitamin D deficiency (P=0.02).
- Female children aged 3-5 years showed a higher risk of vitamin D deficiency, but age and sex were not overall significant factors.
Conclusions:
- Vitamin D deficiency is significantly associated with UTIs in children.
- Vitamin D plays an immunoprotective role against UTIs.
- Screening and supplementation of vitamin D may be a valuable preventive strategy for pediatric UTIs.
Background:
Urinary tract infections (UTIs) are among the most prevalent infectious conditions, particularly in children. Vitamin D deficiency has been implicated in various infections, including UTIs. This study aimed to evaluate the association between serum vitamin D levels and UTIs in children at Amir Kola Children's Hospital.
Methods:
This case-control study was conducted on 120 children, aged 2-18 years, diagnosed with UTIs and referred to Amir Kola Children's Hospital, Babol, Iran. Participants were divided into two groups: 60 UTI cases and 60 healthy controls. Peripheral blood samples were collected for vitamin D analysis, measured via ELISA assay. Statistical analysis was performed using SPSS Version 26.
Results:
The mean serum vitamin D level was 17.70±8.35 ng/mL in the case group and 37.91±12.18 ng/mL in the control group, revealing a significant reduction in vitamin D levels among UTI patients (P<0.001). Additionally, pyelonephritis was associated with severe vitamin D deficiency (P=0.02). Female children aged 3-5 years exhibited a higher risk of vitamin D deficiency, although age and sex did not significantly influence vitamin D levels overall. Vitamin D status was not correlated with hospitalization duration.
Conclusion:
Given its immunoprotective role, vitamin D screening and supplementation may serve as a preventive strategy against UTIs and contribute to improved clinical outcomes in affected children.
