Public Workshop on Emerging Clostridial Disease, May 11, 2006, Atlanta, Georgia

On May 11, 2006, the FDA, the CDC and the NIH held a joint workshop on emerging clostridial diseases (summary and other documents below).

The primary goal of this public workshop was to bring together scientific and public health experts to identify research needs and priorities in order to enable progress in understanding the virulence, pathogenesis, host factors, and nonantimicrobial risk factors contributing to reports of morbidity and mortality associated with Clostridium sordellii and Clostridium difficile.  These infections include cases and clusters of C. sordellii toxic shock syndrome following treatment with mifepristone and misoprostol, C. sordellii sepsis associated with skin grafts, and rapidly fatal toxin-mediated cases of community-associated C. difficile infection.

Three panels, consisting of medical and/or public health representatives from federal government, state governments, and academia, presented data and discussed a number of the complex issues surrounding these two related anaerobic bacteria.

There appeared to be a broad consensus that additional research is necessary to improve the clinical understanding of both C. sordellii and C. difficile.  Participants also stressed that surveillance and communication efforts should continue to be refined and focused on enhancing the epidemiological data about, and awareness among clinicians of both diseases.  The workshop served as an important first step in advancing the understanding of some of the most critical underlying questions surrounding mifepristone, C. sordellii-related deaths, and any potential association between the two.  The workshop also identified that additional important questions remain, for example, the role of toxin production and potential antibiotic use in association with mifepristone.  FDA is committed to continuing to work with others, both within and outside of the federal government, to improve the knowledge of these dangerous diseases and the public health concerns they raise. 

Comments:  Written or electronic comments will be accepted after the workshop until June 15, 2006. The administrative record of the workshop will remain open until June 15, 2006.
