BD gains EU approval for Clostridium difficile diagnostic
test
16 July 2008
BD Diagnostics, a segment of BD (Becton, Dickinson and Company)
(NYSE:BDX), has gained EU approval for the BD GeneOhm Cdiff molecular
assay for the rapid diagnosis of patients with Clostridium difficile
infection (CDI).
The company claims it to be the first CDI diagnostic test that offers
sensitivity, simplicity and speed in one test procedure. BD has also
submitted this assay to the US Food and Drug Administration for
clearance.
CE marked under the European In Vitro Diagnostics Directive for the
identification of toxigenic Clostridium difficile directly from
stool specimens, the BD GeneOhm Cdiff assay targets the toxin B gene,
found in toxigenic Clostriduim difficile strains.
The test combines high assay sensitivity with a rapid turnaround time
of less than two hours, facilitating earlier appropriate treatment of
patients suffering from CDI and earlier implementation of infection
control interventions to prevent transmission of Clostridium
difficile to other patients.
Until now, rapid diagnosis of CDI has been difficult since
traditional methods consist of immunoassays, which lack sufficient
sensitivity, and traditional 'gold standard' tissue culture cytotoxicity
methods, which are difficult to perform and require several days to
yield results.
"The BD GeneOhm Cdiff assay provides a simple and rapid stool test
with excellent sensitivity and specificity that allows same-day
identification of toxigenic Clostridium difficile," said Dr Thomas
Davis, Professor of Pathology and Laboratory Medicine at the Clarian
Pathology Laboratory. "This test should improve patient care because it
effectively eliminates the need for multiple screening and confirmatory
assays, speeds up reporting and helps avoid unnecessary antibiotic use."
"CDI poses a significant challenge for healthcare facilities around
the world," said Jamie Condie, Vice President and General Manager, BD
Diagnostics — GeneOhm.
"The introduction of the BD GeneOhm Cdiff assay demonstrates BD's
ongoing commitment to develop a broad range of products that can help
prevent healthcare-associated infections (HAIs). BD provides molecular
tests for key pathogens associated with HAIs, including methicillin-resistant
Staphylococcus aureus (MRSA), methicillin-susceptible
Staphylococcus aureus, vancomycin-resistant Enterococci, and
now Clostridium difficile."
In the United Kingdom, Clostridium difficile infections have
risen 40% in the last three years, infecting eight times as many
patients as MRSA and killing twice as many. In the United States
annually, an estimated 500,000 people are hospitalized and more than
28,000 die from CDI. The average length of stay for a CDI patient is
nearly three times longer than the average patient and excess healthcare
costs exceed $1 billion. US rates of CDI continue to increase, driven by
a hypervirulent strain known as BI/NAP1/027. This dangerous strain has
now been isolated in at least 38 states, Canada and 14 European
countries.
