[Advances in the treatment of infection in children].

infection (CDI) is a major cause of hospital-acquired gastrointestinal infections in children. Current treatment for pediatric CDI primarily involves antibiotics; however, some children experience recurrence after antibiotic treatment, and those with initial recurrence remain at risk for further recurrences following subsequent antibiotic therapy. In such cases, careful consideration of treatment options is necessary. Fecal microbiota transplantation has been shown to be effective for recurrent CDI and has a high safety profile. This article reviews the latest research on the pathogenesis, risk factors, diagnosis, and treatment of pediatric CDI domestically and internationally, with a particular focus on fecal microbiota transplantation therapy.
