Adverse clinical outcomes associated with multidrug-resistant organisms in patients with infected pancreatic necrosis
2019
Abstract Background Multidrug-resistant organisms (MDROs) is becoming a serious worldwide threat to public health. However, the impact of MDROs on the outcomes of the patients with infected pancreatic necrosis (IPN) remains unclear. This study aims to evaluate the roles of MDROs in IPN. Methods A prospectively maintained database of 188 patients with IPN between January 2010 and May 2019 was analyzed. The microbiology profile of organisms isolated from wall-off necrosis (WON) was specifically investigated to correlate with the outcomes of the patients. Results Of the 188 patients with IPN, 108 patients (57.4%) had MDROs detected in aspirates from WON. Carbapenem-resistant Klebsiella pneumoniae (CRKP) accounted for 43.5% of the MDROs isolated (60/138), followed by Carbapenem-resistant Acinetobacter baumanii (CRAB) (34.8%, 48/138) and Escherichia coli producing an extended-spectrum beta-lactamase (ESBLp) (6.5%, 9/138). MDROs infection was associated with higher mortality (35.2% vs 11.3%, P Conclusions MDROs infection was prevalent among patients with IPN and associated with adverse clinical outcomes and increased mortality.
