BACKGROUND: Abnormal permeability and extensive epithelial injury are characteristic of colon wall damage complicating critical illness, such as sepsis, and associated with mortality. To assess mechanisms of such colon epithelial disruption, we studied expression of markers of innate immunity and intercellular junctions in patients with critical illness. METHODS: Emergency colectomy samples from 38 intensive care unit patients with sepsis, fulminant C. difficile colitis, or colon ischemia were studied...

Clostridium difficile infections are the leading cause of health care-associated infectious diarrhea, posing a significant risk for both medical and surgical patients. Because of the significant morbidity and mortality associated with C difficile infections, knowledge of the epidemiology of C difficile in combination with a high index of suspicion and susceptible patient populations (including surgical, postcolectomy, and inflammatory bowel disease patients) is warranted. C difficile infections present with a wide spectrum of disease, ranging from mild diarrhea to fulminant colitis or small bowel enteritis and recurrent C difficile infections...

Clostridium difficile infection (CDI) is a major cause of nosocomial diarrhea with the potential for significant morbidity and mortality. Colonization in a susceptible individual, with risk factors such as prior antibiotic use, advanced age, or medical comorbidities, may result in symptomatic infection. Although patients with a gynecologic malignancy may be at a higher risk of developing CDI due to an increased likelihood of having one or more risk factors, data do not consistently support the idea that chemotherapy or cancer itself are independently associated with CDI...

Clostridium difficile infection (CDI) is the most common cause of antibiotic-associated diarrhea and colitis in developed countries. The disease is mainly mediated via two major exotoxins TcdA and TcdB secreted by the bacterium. We have previously developed a novel, potently neutralizing, tetravalent and bispecific heavy-chain-only single domain (VHH) antibody to both TcdA and TcdB (designated as ABA) that reverses fulminant CDI in mice. Since ABA has a short serum half-life, in this study a replication-deficient recombinant adenovirus expressing ABA was generated and the long-lasting expression of functional ABA was demonstrated in vitro and in vivo Mice transduced with one dose of the adenovirus displayed high levels of serum ABA for more than1 month and were fully protected against systemic toxin challenges...

Clostridium difficile (C. difficile) infection (CDI) is the most common cause of -healthcare-associated infections in US hospitals. The epidemic strain NAP1/BI/ribotype 027 accounts for outbreaks worldwide, with increasing mortality and severity. CDI is acquired from an endogenous source or from spores in the environment, most easily acquired during the hospital stay. The use of antimicrobials disrupts the intestinal microflora enabling C. difficile to proliferate in the colon and produce toxins. Clinical diagnosis in symptomatic patients requires toxin detection from stool specimens and rarely in combination with stool culture to increase sensitivity...

Clostridium difficile is the most important cause of nosocomial infectious diarrhea in the western world. C. difficile infections are a major healthcare burden with approximately 500,000 new cases every year and an estimated annual cost of nearly $1 billion in the U.S. Furthermore, the infections are no longer restricted to health care facilities, and recent studies indicate spread of C. difficile infection to the community as well. The clinical spectrum of C. difficile infection ranges from asymptomatic colonization to severe diarrhea, fulminant colitis and death...

BACKGROUND: Clostridium difficile is a common cause of hospital-acquired diarrhea, which is usually associated with previous antibiotic use. The clinical manifestations of C. difficile infection (CDI) may range from mild diarrhea to fulminant colitis. Clostridium difficile should be considered in diarrhea cases with a history of antibiotic use within the last 8 weeks (community-associated CDI) or with a hospital stay of at least 3 days, regardless of the duration of antibiotic use (hospital-acquired CDI)...

Introduction. Clostridium difficile is the most common cause of healthcare associated infectious diarrhea, and its most common clinical manifestation is pseudomembranous colitis. Small bowel enteritis is reported infrequently in the literature and typically occurs only in patients who have undergone ileal pouch anastomosis due to inflammatory bowel disease or total abdominal colectomy for other reasons. Presentation of Cases. We report here two cases in which patients developed small bowel C. difficile enteritis in the absence of these underlying conditions...

The most important infectious cause of antibiotic-associated diarrhoea and colitis is Clostridium difficile, which is a Gram-positive, anaerobic, spore-forming, toxin-producing bacillus. In this overview we will discuss the diagnostic and therapeutic management of patients presenting with suspected or proven C. difficile infection (CDI). The clinical spectrum varies from asymptomatic C. difficile carriers to fulminant colitis with multi-organ failure. The onset of symptoms is usually within 2 weeks after initiation of antibiotic treatment...

Clostridium difficile infection is linked to antibiotic exposure, with elderly and immunocompromised hospitalised patients being particularly at risk. The symptoms range from mild diarrhoea to life-threatening fulminant colitis. We describe an unusual presentation of C. difficile infection after closure of ileostomy in a healthy 60-year-old man with a history of low anterior resection and defunctioning ileostomy for rectal tumour. On the third day postoperatively, the patient developed left lower abdominal pain and profuse diarrhoea...

BACKGROUND: Fulminant Clostridium difficile colitis (fCDC) is a highly lethal disease with mortality rates ranging between 12% and 80%. Although often these patients require a total abdominal colectomy (TAC) with ileostomy, there is no established management protocol for post-operative antibiotics. In this study we aim to make some recommendations for post-operative antibiotic usage, while describing the practice across different institutions. METHODS: Multi-institutional retrospective case series including fCDC patients who underwent a TAC between January 1, 2007, and June 30, 2012...

BACKGROUND: The incidence and the severity of Clostridium difficile infection (CDI) have increased significantly over the last decade, especially in high-risk populations such as patients with inflammatory bowel disease (IBD). Surgeons must be able to both identify and minimize the risk of CDI in their own surgical patients and determine which CDI patients will benefit from surgery. PURPOSE: We sought to define the risk factors, compare the treatment options, define the surgical indications, and identify factors that affect surgical outcomes for CDI based on the currently available literature...

Clostridium difficile infection (CDI) can trigger various responses, ranging from asymptomatic carriage to fulminant colitis. Hard-to-cure CDI, such as severe CDI, multiple recurrences of CDI, refractory CDI, and hypervirulent strains of C. difficile, require new treatments, although antibiotics such as metronidazole and vancomycin are the treatment of choice for initial and first relapsing CDI. Active immunization with C. difficile toxins and faecal microbiota transplantation deserve special attention. Here we describe these strategies for difficult-to-treat CDI...

The anaerobic Gram-positive bacterium Clostridium difficile causes intestinal infections responsible for symptoms ranging from mild diarrhea to fulminant colitis. Like other bacteria, C. difficile needs to sense and integrate environmental signals in order to adapt to changes and thrive in its environment. The second messenger cyclic diguanosine monophosphate (c-di-GMP) was recently recognized as a quasi-ubiquitous phenotype coordinator in bacteria. Mostly known to be involved in the transition from motile to sessile and multicellular behaviors in Gammaproteobacteria, c-di-GMP is now known to regulate many other phenotypes from cell morphogenesis to virulence, in many Gram-negative and a few Gram-positive bacteria...

INTRODUCTION: Clostridium difficile infection (CDI) is the most common cause of hospital-acquired diarrhea. Severity of CDI is associated with advanced age and co-morbidities. The clinical spectrum varies from mild watery diarrhea to severe fulminant pseudomembranous colitis with complications. METHODOLOGY: This study conducted over a six-year period (2008 to 2013) included 510 patients treated at the University Hospital for Infectious and Tropical Diseases in Belgrade, Serbia...

Clostridium difficile is widely publicised as a problem in the health-care system. Disruption of the normal gut microbiota by antibiotic therapy allows C. difficile to colonise the colon. On colonisation, C. difficile produces two toxins that lead to disease, with symptoms ranging from mild-to-severe diarrhoea, to fulminant and often fatal pseudomembranous colitis (PMC). How C. difficile establishes initial colonisation of the host is an area of active investigation. Recently there has been increased research into the role of C...

Clostridium difficile is an anaerobic Gram-positive bacterium that causes intestinal infections with symptoms ranging from mild diarrhea to fulminant colitis. Cyclic diguanosine monophosphate (c-di-GMP) is a bacterial second messenger that typically regulates the switch from motile, free-living to sessile and multicellular behaviors in Gram-negative bacteria. Increased intracellular c-di-GMP concentration in C. difficile was recently shown to reduce flagellar motility and to increase cell aggregation. In this work, we investigated the role of the primary type IV pilus (T4P) locus in c-di-GMP-dependent cell aggregation...

Clostridium difficile is the most common cause of nosocomial infectious diarrhea. The incidence of C difficile infection (CDI) is increasing in both inpatients and outpatients, and outbreaks caused by a hypervirulent strain of C difficile are resulting in more severe disease. Moreover, community-associated CDI is occurring in persons who lack the traditional risk factors, which include antibiotic use, advanced age, and severe underlying disease. The clinical severity of CDI ranges from a mild, self-limited diarrheal illness to a fulminant, life-threatening colitis...

Clostridium difficile infection (CDI) is the most common infectious cause of healthcare-acquired diarrhoea. Outcomes of C. difficile colonization are varied, from asymptomatic carriage to fulminant colitis and death, due in part to the interplay between the pathogenic virulence factors of the bacterium and the counteractive immune responses of the host. Secreted toxins A and B are the major virulence factors of C. difficile and induce a profound inflammatory response by intoxicating intestinal epithelial cells causing proinflammatory cytokine release...
