Does the Trace Element Deficiency (Vit A, D & Zinc) Have Any Role in Vulnerability to Urinary Tract Infection in Children: A Case-Control Study: Tehran, Iran

Urinary Tract Infection (UTI) is one of the most common causes of hospital admission in our young population. This prospective cohort study was carried out to assess the relation of serum levels of zinc, vitamins A and D with UTI in children with proven UTI. The serum levels of Zinc, vitamins A and D were compared between 25 proven UTI cases (admitted in 2 educational hospitals in Tehran) and 40 controls without infection (children who had undergone for elective surgery). The average age of children was 2.17 years. Atomic absorption Spectrophotometry, Radioimmunoassay, and HPLC methods were used for measuring the Zinc, Vit D and A, respectively. Although the serum levels of zinc were significantly lower in UTI cases (P=0.05), no significant differences had observed between cases and controls for vitamins A and D in sera (P=0.4 and P=0.9). Due to established lower zinc level in UTI cases (p-value = 0.05), zinc deficiency might have a role in susceptibility to UTI in studied children. Administration of zinc could be helpful in preventing UTI. To establish the role of Vitamins A and D in vulnerability to UTI, further extensive research with larger samples is needed.
