bioMérieux strengthens its Clostridium difficile offer with the launch of VIDAS® C. difficile GDH

26 February, 2014

bioMérieux, a world leader in the field of in vitro diagnostics, is pleased to announce that the launch of VIDAS® C. difficile GDH makes it the only company with the width to provide solutions for C. difficile according to different laboratory settings, patient conditions and medical needs. 

Clostridium difficile is a bacterium recognized as the chief infectious cause of healthcare and antibiotic-associated diarrhea, mainly in elderly patients. In this context, diagnosing C. difficile infections is key to improve patient outcome and avoid complications and septicemia. In addition, an accurate and rapid diagnosis enables to stop contaminations at hospitals and reduce high financial expenses associated with such infections.

As the leader in clinical microbiology testing, bioMérieux’s ambition is that every infectious disease laboratory will find a solution adapted to its need within bioMérieux C. difficile range of products. bioMérieux’s offering already includes chromID® C. difficile culture media and VIDAS® C. difficile Toxin A&B assay for the detection of C. difficile Toxins A&B secreted by the bacteria. In line with this long-standing expertise in C. difficile control and detection, bioMérieux recently launched VIDAS® C. difficile GDH, for the automated detection of GDH, a specific enzyme produced by C. difficile. This innovative, qualitative assay will be used as an aid in the diagnosis and treatment of C. difficile infections in complement to other C. difficile assays. The combination of tests based on GDH, then toxin detection, is recommended by leading international experts as the most valuable C. difficile diagnosis solution.VIDAS® C. difficile GDH has received CE marking and is the only automated immunoassay cleared by the U.S. Food and Drug administration (FDA).

VIDAS® C. difficile GDH was developed and is produced by bioMérieux in France at its Marcy l’Etoile site, where the Company’s global headquarters are located. VIDAS® C. difficile GDH is used on the VIDAS®, mini VIDAS® and VIDAS® 3 automated immunoassay platforms, providing clinical laboratories with a fully automated, accurate, standardized and cost-effective solution for C. difficile diagnosis and infection control. With a reputation for quality and reliability, VIDAS® is the world’s largest installed base of automated immunoassay systems in clinical laboratories.

C. difficile infections are a major concern for both health professionals and hospitalized patients, and are a leading cause of healthcare-associated infections”, said Mark Miller, bioMérieux’s Chief Medical Officer. “We are extremely pleased to enrich our VIDAS® menu with this new test, a welcome addition for our existing offer. Many clinical laboratories will now be able to perform the complete C. difficile detection, based on bioMérieux’s solutions. With this new launch, bioMérieux shows its commitment to the fight against C. difficile infections, providing clinical laboratories with a global offer for C. difficile infection diagnosis and management.”

bioMérieux now offers a full solution for C. difficile, from identification to epidemiology, in order to answer to all customer needs in all infectious disease laboratories: chromID® C. difficile culture media for identification, VIDAS® C. difficile GDH and VIDAS® C. difficile Toxin A&B for automated and cost-effective identification, Etest® for antibiotic susceptibility testing and DiversiLab®, an epidemiological tool for strain typing. This range should soon be enlarged by the FilmArray® Gastrointestinal (GI) Panel, a molecular diagnostics system enabling to rapidly identify pathogens responsible for infectious diarrhea, including C. difficile, in emergency or critical situations. This panel has just been submitted to the U.S. Food and Drug Administration (FDA) for 510(k) clearance.

About Clostridium difficile

C. difficile is the main infectious cause of healthcare-associated diarrhea, and can lead to extremely serious and incapacitating pseudomembranous colitis. C. difficile is highly contagious, due to its oral-fecal route of transmission and the persistence of spores on inert surfaces. It requires drastic measures involving patient isolation, hygiene and disinfection. It is currently ranked by the CDC (Centers for Disease Control and Prevention) as an “urgent public health threat” requiring immediate and aggressive action.2

  • In the U.S., C. difficile is responsible for an estimated 250,000 illnesses and 14,000 deaths per year2
  • In Europe, C. difficile causes 5% of all healthcare-associated infections, leading to 185,000 infections per year.3
  • The annual economic burden of CDI is estimated to be $3 billion per year in the US4 and €3 billion in Europe.5
  • In 2000, a hyper-virulent strain of C. difficile, known as type 027, emerged in Canada and many North American states, and has since spread widely in Europe. This strain type causes more severe infections and is associated with high morbidity and mortality rates (7 to 22% during epidemics in Canada). Between 2000 and 2007, deaths related to C. difficile increased 400% in the US, partly due to the increasing spread of the 027 strain.2

About VIDAS®

With about 28,000 VIDAS®, mini VIDAS® and VIDAS® 3 systems used by clinical laboratory professionals, bioMérieux has the largest installed base worldwide of automated immunoassay systems. Around the world, three VIDAS® tests are performed each second. These systems offer multi-parameter instruments using ELFA (Enzyme Linked Fluorescent Assay) technology, based on a ready-to-use single-sample test concept. The analyses may be run in a series or individually. Launched in 1992, the VIDAS® product range has earned a reputation for quality and reliability. The VIDAS® menu includes 100 parameters covering a wide range of human pathologies: identification and quantification of bacteria, viruses and parasites, antibodies measuring the immunological response to an infection and different proteins circulating in the blood, markers for selected cardiovascular diseases and certain cancers, inflammatory response and hormonal dysfunction.

VIDAS® 3, the new generation of VIDAS®, was granted CE marking in June 2013. VIDAS® 3 features enhanced automation, improved traceability and new software capabilities, as well as a quality control program in compliance with laboratory certification standards. This instrument is commercially available in Europe and the countries that recognize the CE marking. The Company plans to progressively obtain regulatory approval for commercialization in other countries, particularly the United States and China.
