Clinical Report: Predictive Model for Delayed Erythroid Recovery Post-HSCT

Overview

This study identifies independent risk factors for delayed erythroid hematopoietic recovery (DEHR) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) and constructs a predictive model. Key factors include pre-transplant ferritin levels, anemia severity, and donor-recipient ABO compatibility.

Background

Delayed erythroid hematopoietic reconstitution (DEHR) is a significant clinical issue following allo-HSCT, impacting patient recovery and outcomes. Understanding the risk factors associated with DEHR is important for identifying high-risk patients.

Data Highlights

Key Findings

• Ferritin level before transplantation is an independent risk factor for DEHR (OR = 1.001).
• Severity of anemia before transplantation significantly increases the risk of DEHR (OR = 3.740).
• Compatibility of donor and recipient ABO blood types is associated with DEHR risk (OR = 3.283).
• The predictive model achieved an AUC of 0.835, indicating good discrimination.
• Calibration curve slope approached 1, indicating good calibration of the model.
• Nagelkerke R² value of 0.349 suggests moderate explanatory power of the model.

Clinical Implications

The identification of these risk factors allows for monitoring of patients undergoing allo-HSCT.

Conclusion

The developed nomogram provides a tool for predicting DEHR after allo-HSCT, aiding in the identification of patients at high risk.
