Clinical Scorecard: Factors Affecting Peripheral Blood Metrics and Their Impact on 30-Day Mortality in Pediatric Hemophagocytic Lymphohistiocytosis: Insights from a Single-Center Retrospective Cohort Analysis Using Weighted Quantile Sum Regression

At a Glance

Key Highlights

• Significant association of RDW, MCH, HCT, and Hb with early mortality risk.
• WQS regression model indicated a protective effect of improved peripheral blood parameters.
• MCH and HCT were identified as core parameters with the highest predictive weights.
• Combined predictive model showed improved efficacy with an AUC of 0.728.
• DCA confirmed clinical net benefit of the combined model over single parameters.

Guideline-Based Recommendations

Diagnosis

• Utilize peripheral blood parameters for early identification of mortality risk.

Management

• Consider the joint effects of peripheral blood metrics in treatment planning.

Monitoring & Follow-up

• Regularly assess RDW, MCH, HCT, and Hb levels in pediatric HLH patients.

Risks

• Monitor for severe coagulopathy, CNS involvement, and refractory infections.

Patient & Prescribing Data

133 pediatric HLH patients

Early identification of high-risk patients through peripheral blood metrics.

Clinical Best Practices

• Incorporate WQS regression for evaluating joint effects of clinical variables.
• Focus on MCH and HCT as key indicators in pediatric HLH management.
