Risk factors for the emergence of multidrug-resistant organisms in liver cirrhosis

•This study gives information about multidrug-resistant organisms (MDROs) infections in liver cirrhosis (LC) focusing on its risk factors.•Use of proton pump inhibitors (PPI), antibiotics and hospitalization increase the risk of MDROs infections.•Our manuscript creates an opportunity for future studies of other risk factors predisposing to the emergence of MDROs in LC.•This is the first study that identifies PPI as risk factors for MDROs infections in LC and a statistical association between MDROs infection and 90-day mortality.
