Carbapenem-resistant Acinetobacter baumannii and Ventilator-associated Pneumonia; Epidemiology, Risk Factors, and Current Therapeutic Approaches
Abstract
A BSTRACT Acinetobacter baumannii is one of the primary pathogens responsible for healthcare-associated infections. It is related to high rates of morbidity and mortality globally, mainly because of its high capacity to develop resistance to antimicrobials. Nowadays, carbapenem-resistant A. baumannii (CRAB) has increased and represents a significant concern among carbapenem-resistant organisms. It is also a key pathogen associated with ventilator-associated pneumonia. CRAB was placed on the critical group of the universal priority list of the World Health Organization for antibiotic-resistant bacteria, to mention the importance of research development and the urgency of new antibiotics. Patients with severe CRAB infections currently face significant treatment challenges. Some approaches have been taken to deal with CRAB, such as combination therapy and the synergistic effect of certain antibiotics, but the best antibiotic regimen is still unknown. In this narrative review, we attempt to clarify the issues, including epidemiology, risk factors, and current treatment options for CRAB.
