Psychiatric Status and Symptom Severity in Graft-versus-Host Disease (GvHD).

Graft-versus-host disease (GvHD) is a significant complication following allogeneic hematopoietic stem cell transplantation and is associated with substantial symptom burden, impaired quality of life, and increased psychiatric morbidity. Despite its clinical relevance, the relationship between psychiatric status and the severity of GvHD-related symptoms remains insufficiently characterized.

This prospective observational study aims to systematically assess psychiatric status, symptom severity, and health-related quality of life in patients with GvHD using standardized and validated instruments. Demographic and clinical data will be collected to establish a comprehensive patient registry. The study will evaluate the association between psychiatric disorders and the intensity of GvHD-related symptoms, as measured by the Lee Symptom Scale, and will explore the bidirectional relationship between depressive symptoms and the clinical course of GvHD. The findings are expected to inform the development of evidence-based recommendations for therapeutic support aimed at improving clinical outcomes and quality of life in patients with GvHD.
