N-Acetylcysteine’s Potential Role in Prophylaxis and Treatment of Pediatric Urinary Tract Infections: From Evidence to Patient-Side Research

Urinary tract infections (UTIs) are the most common bacterial infections in children, occurring both in children with normal urinary tracts and in ones with urinary tract abnormalities. Children with UTIs can present relevant clinical symptoms and risk long-term consequences. Current recommended preventive measures include chemoprophylaxis and dietary supplements such as cranberry, probiotics and vitamins A and E. Although chemoprophylaxis still represents the gold standard, it raises concerns about antimicrobial resistance. N-acetylcysteine (NAC), a precursor of the antioxidant glutathione, has been proven both to inhibit biofilm formation and to destroy developed biofilms. In adults, NAC has been demonstrated to prevent UTIs and to improve the effect of antibiotics, but so far it has not been analyzed as an antimicrobial option for pediatric UTIs. In this work, we aim to discuss the current applications of NAC in adult urology and its future possible evolutions in pediatric urology.
