  • Title: Life-threatening clostridial infections.
    Author: Stevens DL, Aldape MJ, Bryant AE.
    Journal: Anaerobe; 2012 Apr; 18(2):254-9. PubMed ID: 22120198.
    Abstract:
    Life-threatening soft tissue infections caused by Clostridium species have been described in the medical literature for hundreds of years largely because of their fulminant nature, distinctive clinical presentations and complex management issues. The Clostridium species perfringens, septicum and histolyticum are the principal causes of trauma-associated gas gangrene and their incidence increases dramatically in times of war, hurricanes, earthquakes and other mass casualty conditions. Recently, there has also been an increased incidence of spontaneous gas gangrene caused by Clostridium septicum in association with gastrointestinal abnormalities and neutropenia. Similarly, over the last 15 years there has been increased recognition of a toxic shock-like syndrome associated with Clostridium sordellii in individuals skin-popping black tar heroin, in women undergoing childbirth or other gynecologic procedures including medically-induced abortion. Like their cousins Clostridium tetanus and Clostridium botulinum, the pathogenesis of these clostridial infections is largely the consequence of potent exotoxin production. Strategies to inhibit toxin production, neutralize circulating toxins and prevent their interaction with cells of the innate immune response are sorely needed. Recent studies have elucidated novel targets that may hold promise for newer therapeutic modalities.
