Novel Hematological Biomarker Adopted for Early Sepsis Detection Emerges as Predictor of Severity for COVID Infection

Area of Science:

• Hematology
• Infectious Diseases
• Critical Care Medicine

Background:

• Sepsis presents a significant global health challenge, impacting morbidity, mortality, and healthcare resources.
• Monocyte Distribution Width (MDW) is a hematological biomarker utilized for early sepsis detection.
• Observed similarities between COVID-19 and sepsis laboratory data prompted further investigation.

Purpose of the Study:

• To assess the predictive value of hematological data, including MDW, for COVID-19 disease severity and patient outcomes.
• To identify specific hematological patterns indicative of severe COVID-19 at the time of emergency room presentation.

Main Methods:

• Retrospective analysis of 130 COVID-19 patients admitted between March and April 2020.
• Inclusion of clinical, laboratory (including MDW, absolute neutrophil count (ANC), and absolute lymphocyte count (ALC)), and radiological findings.
• Evaluation of hematological biomarkers for prediction of disease severity and outcome.

Main Results:

• A distinct hematological pattern emerged in predicting COVID-19 severity and outcomes.
• Higher absolute neutrophil count (ANC) was associated with increased severity.
• Lower absolute lymphocyte count (ALC) and higher Monocyte Distribution Width (MDW) were also predictive of adverse outcomes.

Conclusions:

• The combination of elevated ANC, decreased ALC, and increased MDW serves as a valuable predictor of COVID-19 severity and outcome at initial ER presentation.
• These hematological biomarkers offer a potential tool for early risk stratification of COVID-19 patients.
• Further research can explore the integration of these markers into clinical decision-making for COVID-19 management.
