Multidrug-resistant (MDR) bacterial infection is a common complication of severe acute pancreatitis (SAP). This study aimed to explore the association between human leukocyte antigen-antigen D-related (HLA-DR) expression and multidrug-resistant infection in patients with SAP. A total of 24 SAP patients who were admitted to Nanjing Drum Tower Hospital between May 2015 and December 2016 were enrolled in the study. The percentages of CD4+, CD8+, natural killer (NK), and HLA-DR (CD14+) cells and the CD4+/CD8+ cell ratio on days 1,7,14, and 28 after admission were determined by flow cytometry. Eighteen patients presented with the symptoms of infection. Among them, 55.6% patients (10/18) developed MDR infection. The most common causative MDR organisms were Enterobacter cloacae and Acinetobacter baumannii. The CD4+/CD8+ cell ratio and the percentage of NK cells were similar between patients with non-MDR and patients with MDR infections. In patients without infection, the HLA-DR percentage was maintained at a high level throughout the 28 days. Compared to the patients without any infection, the HLA-DR percentage in patients with non-MDR infection was reduced on day 1 but increased and reached similar levels on day 28. In patients with MDR infection, the HLA-DR percentage remained below normal levels at all-time points. It was concluded that persistent down-regulation of HLA-DR expression is associated with MDR bacterial infection in patients with SAP.
