The Association between Vitamin D Levels and Urinary Tract Infection in Children

Area of Science:

• Pediatric Nephrology
• Nutritional Immunology
• Infectious Diseases

Background:

• Urinary tract infections (UTIs) are common in children.
• Vitamin D plays a crucial role in immune function.
• The association between vitamin D levels and UTI risk in children requires further investigation.

Purpose of the Study:

• To investigate the relationship between serum 25-hydroxyvitamin D [25(OH)D3] levels and the occurrence of urinary tract infections (UTIs) in children.
• To determine if vitamin D deficiency is a risk factor for UTIs in pediatric patients.

Main Methods:

• A case-control study was conducted involving 82 children with a first UTI episode and 64 healthy controls.
• Serum levels of 25-hydroxyvitamin D [25(OH)D3] and other biochemical markers were measured.
• Multivariate analysis was used to assess the association between 25(OH)D3 levels and UTI.

Main Results:

• Children with UTI had significantly lower mean serum 25(OH)D3 levels compared to controls (11.7 vs. 27.6 ng/ml).
• Lower 25(OH)D3 levels were observed in acute pyelonephritis and in girls compared to boys.
• Serum 25(OH)D3 levels below 20 ng/ml were associated with an increased risk of UTI (OR 3.503).

Conclusions:

• Vitamin D deficiency is significantly associated with an increased risk of urinary tract infections in children.
• These findings suggest that maintaining adequate vitamin D levels may be important for preventing UTIs in pediatric populations.
• Further research is warranted to explore the therapeutic potential of vitamin D supplementation in UTI prevention.
