Measurement of suPAR in patients with 1 point of qSOFA score identifies patients that will benefit from antibiotic treatment

Sepsis is a deadly disease and is estimated to account for around 11 million deaths annually. Early treatment is pivotal but often not initiated, as early diagnosis is missed.

Current guidelines suggest that patients admitted to the emergency department (ED) should be treated for sepsis if they have at least two of three signs of risk for sepsis (2 or 3 points in the qSOFA score system). However, if a patient has only one sign of risk, treatment is often delayed to limit the use of unnecessary antibiotics. However, some patients with only one risk sign require early treatment to prevent progression and the challenge is to find the ones that benefit from early treatment.

In the study 1650 patients were screened for their suPAR level in the ED using suPARnostic® and 91 patients with a qSOFA score of 1 and suPAR equal to or above 12 ng/ml were randomized to receive either one dose of meropenem, an antibiotic treatment (44 patients), or one dose of placebo (47 patients). The study met its primary endpoint: Meropenem treatment guided by suPARnostic® was accompanied by significantly lower odds for progression into sepsis compared to placebo (OR: 0·28, 95% CI 0·10 – 0·76, p = 0·012). An additional significant benefit for patients treated early with meropenem was a relative decrease in their SOFA score on day 2 and a significantly faster recovery from the infection.

The study demonstrates suPAR measurement’s efficacy in identifying high-risk patients with one qSOFA point. Early meropenem treatment benefits this subgroup, aiding in sepsis management by promptly initiating antibiotics. The findings emphasize suPAR’s role in guiding antibiotic treatment for uncertain sepsis risk.
