Pre-transplant microRNA serum profiles and association with acute graft-versus-host disease in allogeneic hematopoietic stem cell transplantation
To evaluate whether serum miRNA expression profiles obtained prior to transplantation can serve as a predictive tool for aGVHD in allo-HSCT recipients, focusing on early detection.
Key Findings:
18 patients (23%) developed aGVHD grade II–IV, highlighting the clinical relevance of early prediction.
ROC analysis identified eight pretransplant miRNAs associated with aGVHD development.
A predictive model based on these miRNAs achieved an AUC of 0.855, decreasing to 0.692 after bootstrap validation.
Hierarchical clustering separated patients into two clusters with significantly different aGVHD risks, emphasizing the potential for tailored interventions.
Interpretation:
Pre-transplant serum miRNA signatures can predict aGVHD risk and severity, suggesting potential for early patient stratification and future research directions.
Limitations:
Study cohort was limited to 78 patients.
Further validation in independent cohorts is warranted.
The retrospective nature of the study may introduce bias.
Conclusion:
Pre-transplant serum miRNA profiling may guide personalized GVHD prophylaxis and monitoring, potentially improving patient outcomes.
