Core Tip
Core Tip: Recurrent urinary tract infections (UTIs) promote the progression of kidney damage in children with congenital anomalies of the kidney and urinary tract, potentially leading to chronic kidney disease. The rising burden of antimicrobial resistance highlights the need for effective nonantibiotic preventive strategies. This randomized, double-blinded, placebo-controlled trial explores oral bovine colostrum (BC), a bioactive prebiotic with immunomodulatory properties, as an adjuvant therapy in these children. Although overall UTIs reduction was not statistically significant, BC significantly reduced cystitis, and showed delayed, month-specific reductions in UTIs, alongside fewer respiratory and gastrointestinal infections. These findings suggest a potential cumulative immunomodulatory benefit of BC in vulnerable pediatric populations.
