Brief Summary

Soluble Urokinase Plasminogen Activation Receptor (SUPAR) is a validated biomarker with applications in the study of inflammation and infection.

Elevated levels of SUPAR have recently been linked to a higher mortality in patients suffering from undifferentiated sepsis, pneumonia, and more recently, COVID-19 infection.

Large randomized controlled trials have been conducted on patients admitted to the emergency department (ER), regardless of the reason for admittance.

These studies have stratified risk based on three cutoffs at initial measurement:

• Low risk : < 3 ng/mL
• Intermediate risk : entre 3 et 6 ng/mL
• High risk : > 6 ng/mL Low levels of SUPAR are associated with low risk of mortality in the short and long term in patients presenting to the ED, no matter the reason for admittance. Risk stratification could be an added decision-making tool for clinicians to comfort hospital discharge.

To the best of our knowledge, there is no available data on the added value of SUPAR for predicting mortality in abdominal sepsis and abdominal pain.

Abdominal pain is responsible for 10 to 30 % of ER admissions. Consequently, abdominal pain is then responsible for roughly 10 % of admissions into medical and surgical wards. Mortality varies depending on patient factors. Mortality is usually stratified on age. In patients under 50 years of age, it is near 8%, but it reaches 19 % in patients over 50.

Diagnostic accuracy also decreases drastically with age, reaching approximately 30 % patients over 75.

Taking this into account, integrating a measure of SUPAR levels into the current standard of care could stratify the risk of complications in patients admitted to the ER with abdominal pain.
