Sepsis is a life-threatening organ dysfunction caused by the body’s toxic response to infection and can progress to septic shock, which has a mortality rate of 40%. A blood culture is the main way to check for the microbial agent (bacteria or fungi) causing the infection and will allow to diagnose the bacteremia or fungemia as well as determine the sensitivity of these microorganisms to antibiotics and antifungals. The speed at which appropriate treatment can be administered, based on the type of infection, determines the survival of the patient. Now, a new in-vitro diagnostic solution for microbial infections identifies the pathogen(s) as well as allows to identify and predict the resistance profile within 90 minutes to ensure that the appropriate anti-infective treatment can be adapted or administered quickly, reducing the risk of death in severe systemic infections.

Weezion’s (Lyon, France) Weezion dx solution is based on a proteomic approach using patented targeted mass spectrometry technology and identifies the pathogen(s) present in the clinical sample, as well as jointly detects and quantifies the proteins responsible for antibiotic resistance. Using a positive blood culture, the solution allows clinicians to identify and predict the resistance profile within 90 minutes.

Despite major advances in the last 20 years in understanding the pathophysiology of sepsis, no therapeutic revolution has yet seen the light of day. It is therefore in the diagnostic phase where progress can be made. Reducing the time to receive the results of the identification of the pathogen and its resistance profile will ensure a more rapid implementation or adaptation of a suitable anti-infective treatment. Existing identification methods, based on the molecular detection of the main pathogens and some of their resistance genes, are expensive and non-exhaustive. MALDI/TOF mass spectrometry technology has shortened the identification phase but does not provide any prediction of resistance. The rapid antibiogram from a positive blood culture vial takes several hours of incubation before validation and most of the technologies used are expensive. Therefore there is an urgent need for a resistance identification and determination tool that is rapid, more comprehensive than current methods and economically sustainable.

Designed for medical analysis hospital platforms that diagnose bacteremia, the Weezion dx solution is comprised of an operational pre-analytical sample protocol from a blood culture aliquot that requires limited manual or automated steps, in less than 10 minutes. It follows a global analytical protocol that guarantees a 90-minute diagnostic phase and allows the management of three blood culture samples per hour in order to satisfy the maximum flow of large hospital microbiology platforms. It includes prototype software to manage the decision tree of the mass spectrometry and enables identification of a panel of scout ribosomal peptides specific to microbial families or species that allows for the implementation of a decision tree to ensure accurate identification of 98% of pathogens associated with bacteremia. The Weezion dx solution also enables the identification of a panel of peptides that detects the resistance mechanisms to the three main types of antibiotics used to treat bacteremia.
