INTRODUCTION: Organ dysfunction remains a major cause of morbidity after trauma. The development of organ dysfunction is determined by the inflammatory response, in which neutrophils are important effector cells. A femoral fracture particularly predisposes for the development of organ dysfunction. This study investigated the chronologic relation between neutrophil characteristics and organ dysfunction in trauma patients with a femoral fracture.
METHODS: Patients with a femoral fracture presenting at the University Medical Center Utrecht between 2007 and 2013 were included. Data of neutrophil characteristics from standard hematological analyzers were recorded on a daily basis until the 28th day of hospital stay or until discharge. Generalized Estimating Equations were used to compare outcome groups.
RESULTS: In total 157 patients were analyzed, of whom 81 had polytrauma and 76 monotrauma. Overall mortality within 90 days was 6.4% (n = 10). Eleven patients (7.0%) developed organ dysfunction. In patients who developed organ dysfunction a significant increase in neutrophil count (P = 0.024), a significant increase in neutrophil cell size (P = 0.026), a significant increase in neutrophil complexity (P < 0.004), and a significant decrease in neutrophil lobularity (P < 0.001) were seen after trauma. The rise in neutrophil cell size preceded the clinical manifestation of organ dysfunction in every patient.
CONCLUSION: Patients who develop organ dysfunction postinjury show changes in neutrophil characteristics before organ dysfunction becomes clinically evident. These findings regarding post-traumatic organ dysfunction may contribute to the development of new prognostic tools for immune-mediated complications in trauma patients.
LEVEL OF EVIDENCE: Level II, etiologic study.
