A prospective, multicenter, cross-sectional study was published on October 7, 2017 in the Journal of Clinical Medicine in an article entitled, “Diagnostic Accuracy of FebriDx: A Rapid Test to Detect Immune Responses to Viral and Bacterial Upper Respiratory Infections.” This clinical trial enrolled adults and children with upper respiratory infections (URIs) to evaluate the diagnostic accuracy of the FebriDx test to identify clinically significant bacterial infections with host response and acute pathogenic viral infection in patients who presented with a history of fever in the outpatient setting.

This study enrolled 370 patients, 205 symptomatic patients with URI and 165 asymptomatic patients from 10 clinical sites in the U.S. For bacterial detection, agreement between FebriDx and the reference standard was 92%, with FebriDx having a sensitivity of 80% and specificity of 93%. Bacterial sensitivity increased further in patients that had a confirmed fever at the time of enrollment. Most importantly, FebriDx demonstrated a negative predictive value (NPV) of 97% for bacterial infection. For viral detection, agreement was 84%, sensitivity ranged between 86-87%, specificity was 83-88%, and the NPV was 93-95% depending on the comparator method. Additionally, 38% of viral infections generated elevated CRP and would lead to antibiotic overtreatment if the CRP result was used independently of MxA.

As reported in a recent article by the International Business Times UK (IBTimes UK), “without any solution, it is estimated that antibiotic resistance will lead to the loss of 10 million lives a year around the world by 2050.”

IBTimes UK highlighted breaking research published this week in Scientific Reports from a team of scientists who have identified the underlying agents that potentially trigger a high level of resistance to vancomycin. Vancomycin has become a critical line of defense in treating some of the most severe infections (think pneumonia, meningitis, sepsis), so understanding what causes this bacterial resistance can potentially lead to future research that disrupts this pattern.


According to the article, “the scientists hope that their work will provide scientists with new tools to win the global fight against antibiotic resistance.”

As antibiotic resistance continues to spread worldwide, it is critical to protect our current antibiotics through research, accelerate the development of new antibioitics, and also introduce diagnostic tests, like FebriDx®, to foster stronger antibiotic stewardship.
