Allogeneic hematopoietic stem cell transplantation (HSCT) is a treatment for many diseases; however, it can induce complications such as Oral Mucositis (OM) and Graft-versus-Host Disease (GVHD). The neutrophil-lymphocyte ratio (NLR) is a peripheral biomarker of systemic inflammation and an independent prognostic factor for several inflammatory diseases.
Aim
This study aimed to evaluate the association of NLR with OM and GVHD in patients undergoing allogeneic HSCT.
Methods
Patients who underwent allogeneic HSCT at the Bone Marrow Transplant Service of the Hospital de Clínicas Complex of the Federal University of Paraná were included in the study. Socio-demographic data and blood counts were collected from patients’ medical records. The NLR was calculated and associated with OM and GVHD.
Results
45 patients were included in the study. Although NLR was higher in patients with OM and oral GVHD, no statistical difference was observed, and no relationship between OM and GVHD with NLR could be stated.
Conclusion
Although both OM and GVHD are associated with an inflammatory response as well as the immune system, it was not associated with NLR. Further investigation considering other variables related to HSCT might find possible associations, as it could favor patient management and prevention.
