Predictive Value of Red Blood Cell Distribution Width, Platelet Count to Lymphocyte Count Ratio, and Neutrophil Count to Lymphocyte Count Ratio Values for the Detection of Postoperative Infection in Patients Undergoing Liver Transplantation

The red blood cell distribution width (RDW) value is a simple and fast parameter that shows an elevation in the presence of infectious disease. It is thought that proinflammatory signals cause changes in the cell wall of the erythrocytes. In our study, we aimed to investigate the prognostic value of RDW and other parameters in patients undergoing liver transplantation. We retrospectively investigated 200 patients who underwent liver transplantation (LT) in our center. The study group was 100 patients who underwent LT and developed a postoperative abdominal or catheter-related infection in the early period between the first and second weeks of hospitalization. The control group comprises 100 patients who underwent LT and were discharged without complications. In 4 different periods, inflammatory markers and RDW, platelet count to lymphocyte count ratio, and neutrophil count to lymphocyte count ratio (NLR) values were compared in the 2 groups. In our study, we found RDW and NLR parameters to be elevated in correlation with infection in patients who underwent LT (P < .05). Other markers were elevated but not significantly correlated with infection. These parameters can be simple and effective additional tools to implement in patients suspected of infection. Further prospective studies with larger patient groups and varying infection states are required for validating RDW and NLR as additional diagnostic markers.
