Elevated Soluble Urokinase-Type Plasminogen Activator Receptor Levels, Organ Dysfunction, and Death in Children...

Area of Science:

• Biomarkers
• Malaria Research
• Critical Care Medicine

Background:

• Soluble urokinase-type plasminogen activator receptor (suPAR) is an emerging biomarker for critical illnesses.
• Elevated circulating suPAR levels are observed in severe malaria and correlate with mortality risk.

Purpose of the Study:

• To identify clinical predictors associated with elevated plasma suPAR levels (≥15ng/mL) in children with severe malaria.
• To assess the utility of suPAR in identifying high-risk pediatric malaria patients.

Main Methods:

• Analysis of plasma suPAR levels in 1226 Ugandan children diagnosed with severe malaria.
• Evaluation of clinical and laboratory parameters as predictors of elevated suPAR.

Main Results:

• Elevated suPAR was detected in 22.1% of the study cohort.
• High suPAR levels were independently linked to severe acute kidney injury, hyperlactatemia, and coma.
• suPAR elevation also correlated with markers of immune and endothelial activation.

Conclusions:

• Clinical predictors for elevated suPAR in severe malaria include coma and kidney injury.
• An optimized clinical decision algorithm prioritizing suPAR testing in children with danger signs may improve risk stratification.
• suPAR testing can enhance the identification of children with severe malaria at highest risk of mortality.
