Clostridium Difficile

Clostridium difficile is a Gram-positive, spore-forming, anaerobic bacillus bacteria. Clostridium difficile infection is considered one of the healthcare-associated infections (HAIs) and the leading cause of healthcare-associated diarrhea (antibiotic-associated pseudomembranous colitis). C. difficile exists in soil, food and colonizes the gastrointestinal tract of several animals and human beings.1 It is estimated that about 5–15% of adults, up to 84.4% of newborns and infants, and nearly 57% of long-term care facilities’ residents are carriers of C. difficile. 2

Exposure and Transmission Characteristics:

difficile-associated colitis is à toxin-mediated disease and several virulence factors have been implicated in its pathogenesis; First, modification of normal gastrointestinal microbiota by administration of antibiotics.3 Second, Acquiring a toxigenic strain of Clostridium difficile, which produces toxins: C. difficile toxins A (TcdA), B (TcdB) 4 and binary toxin (CDT).5 Third, the host immune system response.
Among individuals who are colonized by C. difficile, 10 % to 60 % will develop clinical manifestations of C. difficile-infection CDI. 6-10
Symptoms of CDI may start while the patient is on antibiotic therapy or 5 to 10 days after stopping the antibiotics; infrequently, as late as 10 weeks later. The median incubation period from C difficile acquisition to CDI to be < 7 days. CDI presents as a mild to moderate diarrhea accompanied by lower abdominal pain, and fever. This presentation is often resolved by discontinuing the responsible antibiotics. On the other hand, CDI can produces very severe colitis with or without pseudo-membrane production. This presentation is often associated with low to high-grade fever, abdominal pain and distention. Approximately 3 % of CDI cases present with acute and fulminant colitis with toxic megacolon. In addition, patients with severe disease may develop ileus and present with abdominal distention without diarrhea that may put patients at high risk of colon …show more content…

16 This CDI seasonality follows, with a lag of 2-3 months, the peak seasonality of antibiotic consumption. Moreover, in the past 10 years, the epidemiology of C. difficile has evolved to include community-acquired cases. 17,18 The proportion of community-acquired CDI cases reported ranged from 10 to 50 %. In the U.S., an investigation of the epidemiology of community-associated CDI between 2009 and 2011 showed that 82 % of patients acquiring C. difficile in the community had no recent healthcare exposure. Furthermore, that 36% of patients had not received antibiotics during the previous 12 weeks, but did have significant exposure to proton-pump inhibitor (PPI) agents.
