The correlation between intestinal colonization and infection of carbapenem-resistant Klebsiella pneumoniae: a systemactic review
Journal of Global Antimicrobial Resistance(2024)
Abstract
As a widely spread Gram-negative bacteria, klebsiella pneumoniae mainly causes acquired infections in hospitals, such as lung infections, urinary tract infections, bloodstream infections, etc. In recent years, the number of multidrug-resistant K. pneumoniae strains has increased dramatically, posing a great threat to human health. Carbapenem-resistant Klebsiella pneumoniae (CRKP) can be colonized in human body, especially in gastrointestinal tract, and some colonized patients can be infected during hospitalization, among which invasive operation, underlying disease, admission to intensive care unit, antibiotic use, severity of the primary disease, advanced age, operation, coma and renal failure are common risk factors for secondary infection. Active screening and preventive measures can effectively prevent the occurrence of CRKP infection. Based on the epidemiological status, this study aims to discuss the correlation between colonization and secondary infection induced by carbapenem-resistant Klebsiella pneumoniae and risk factors for their happening, and provide some reference for nosocomial infection prevention and control.
