A 75-year-old man was admitted with abdominal pain and fresh rectal bleeding. Significantly, he had no risk factors for Clostridium difficile infection. An abdominal CT demonstrated colonic thickening, and flexible sigmoidoscopy identified pseudomembranous colitis-like lesions. After initial treatment as C. difficile colitis, a stool sample revealed Escherichia coli O157:H7 infection. Antibiotic therapy was stopped due to the risk of lysis-mediated toxin release, but unfortunately, the patient continued to deteriorate...

Antibiotic-associated colitis is a gastrointestinal complication of antibiotic use commonly seen in hospitalised patients, with Clostridium difficile (C. difficile) colitis being the most common type. We present a case of haemorrhagic colitis secondary to Klebsiella oxytoca following self-initiated amoxicillin-clavulanic acid use. An 85-year-old woman presented to the emergency department with abdominal pain and mucobloody diarrhoea. History was notable for an ongoing 5-day course of amoxicillin-clavulanic acid use...

Clostridioides difficile (formerly Clostridium difficile) is a major nosocomial pathogen with an increasing number of community-acquired infections causing symptoms from mild diarrhea to life-threatening colitis. The pathogenicity of C. difficile is considered to be mainly associated with the production of genome-encoded toxins A and B. In addition, some strains also encode and express the binary toxin CDT. However; a large number of non-toxigenic C. difficile strains have been isolated from the human gut and the environment...

BACKGROUND: Fulminant Clostridium difficile colitis (fCDC) occurs in 2%-8% of patients with CDC and carries a high death rate. Prompt operation may reduce death. Our aim was to determine whether a standardized hospital-wide protocol for surgical referral in CDC would result in earlier surgical consultation, earlier identification of patients who could benefit from surgical therapy, and reduced deaths from fCDC. METHODS: A multidisciplinary team developed consensus criteria for surgical consultation...

Fecal microbiota transplantation (FMT) has evolved from a case report in the medical literature to the basis of major innovations in the treatment of Clostridium difficile infection (CDI) and, potentially, inflammatory bowel disease (IBD). In the clinical setting, FMT was noted to significantly lower the risk of recurrent CDI, likely by increasing microbial diversity and altering the metabolic environment in the intestinal tract of recipients. In parallel, advances in the ability to quantify and characterize microbial communities in fecal samples led to the association of IBD with a state of intestinal dysbiosis...

Extraintestinal Clostridium difficile is rare. A 74-year-old man with a history of ulcerative colitis presented after a fall. Trauma work-up showed liver cirrhosis. Two days later he developed abdominal pain, distension, diarrhoea and leucocytosis. Stool tested positive for C. difficile CT abdomen showed pancolitis with toxic megacolon. Total abdominal colectomy and ileostomy with a rectal stump was performed. He was discharged, but was readmitted with sepsis. CT abdomen showed a 10.4×7.2 cm fluid collection in the pelvis...

BACKGROUND: It is a challenge to diagnosis Clostridium difficile colitis. OBJECTIVES: To determine, among patients who developed nosocomial diarrhea, whether serum procalcitonin (PCT) can distinguish between C. difficile toxin (CDT)-positive and CDT-negative patients. METHODS: This prospective study included 50 adults (>18 years) who developed diarrhea during hospitalization, 25 with a positive fecal test for CDT (study group) and 25 CDT negative (control group)...

Clostridium difficile is the leading cause of hospital-acquired diarrhea and pseudomembranous colitis worldwide. The organism produces two homologous toxins, TcdA and TcdB, which enter and disrupt host cell function by glucosylating and thereby inactivating key signalling molecules within the host. As a toxin-mediated disease, there has been a significant interest in identifying small molecule inhibitors of the toxins' glucosyltransferase activities. This study was initiated as part of an effort to identify the mode of inhibition for a small molecule inhibitor of glucosyltransferase activity called apigenin...

The microbiome is increasingly recognized as an important influence on human health and many of the comorbidities that affect patients after solid organ transplantation (SOT) have been shown to involve changes in gut bacterial populations. Thus, microbiome changes in an individual patient may have important health implications after SOT but this area remains understudied. We describe changes in the composition of the fecal microbiome from a pediatric heart transplant recipient before and >2.5 years after he underwent repeated fecal microbiota transplantation (FMT) for recurrent Clostridium difficile infection (CDI)...

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...

BACKGROUND: Clostridium difficile is an important cause of infectious colitis among hospitalized patients across the globe. The pathogenic potential of C. difficile in producing significant morbidity and mortality is mainly due to production of toxins A and B. The outbreaks of C. difficile infection (CDI) are due to changes in the genetic sequences of the organism. There is hardly any molecular study reported on the prevalent types of C. difficile strains in India. Toxinotyping and sequencing of locally circulating C...

A 62-year-old man developed a blood stream infection and meningitis due to Listeria monocytogenes, 20 days after an episode of pseudo-membranous colitis. The patient, hospitalized for the first time for transurethral prostatectomy, was readmitted 20 days later with watery diarrhea. Pseudo-membranous colitis was diagnosed and treated successfully, without testing for Clostridium difficile infection (CDI). After 15 more days, the patient developed again diarrhea, fever and confusion. Hospitalized again, blood and cerebrospinal fluid cultures resulted positive for L...

Enteric glial cells (EGCs) are components of the intestinal epithelial barrier essential for regulating the enteric nervous system. Clostridium difficile is the most common cause of antibiotic-associated colitis, toxin B (TcdB) being the major virulence factor, due to its ability to breach the intestinal epithelial barrier and to act on other cell types. Here we investigated TcdB effects on EGCs and the activated molecular mechanisms. Already at 2 hours, TcdB triggered ROS formation originating from NADPH-oxidase, as demonstrated by their reduction in the presence of the NADPH-oxidase inhibitor ML171...

Breast milk has many beneficial properties and unusual characteristics including a unique fat component, termed milk fat globule membrane (MFGM). While breast milk yields important developmental benefits, there are situations where it is unavailable resulting in a need for formula feeding. Most formulas do not contain MFGM, but derive their lipids from vegetable sources, which differ greatly in size and composition. Here we tested the effects of MFGM supplementation on intestinal development and the microbiome as well as its potential to protect against Clostridium difficile induced colitis...

The clinical spectrum of Clostridium difficile infection can range from benign gastrointestinal colonization to mild diarrhea and life threatening conditions such as pseudomembranous colitis and toxic megacolon. Extraintestinal manifestations of C. difficile are rare. Here, we report a patient with a history of an endovascular aortic aneurysm repair (EVAR) presenting with an endovascular leak complicated by C. difficile bacteremia and a mycotic aneurysm. He was successfully treated with an explant of the EVAR, an aorto-left renal bypass, and aorto-bi-iliac bypass graft placement along with a six-week duration of intravenous vancomycin and oral metronidazole...

Clostridium difficile is a serious epidemiological problem and particularly dangerous microorganism causing hospital infections. Currently, the treatment of C. difficile infections is the use of metronidazole or vancomycin. However, in some patients, recurrent infection difficult to treat occurs. Fecal microbiota transplantation (FMT) is a new method used to treat the recurrent CDI. FMT consists in the infusion of the fecal suspension from a healthy donor into the gastrointestinal tract of a patient with CDI to restore the natural intestinal microflora...

Clostridium difficile (C. difficile) is a spore-forming, toxin-producing, gram-positive anaerobic bacterium that is the principal etiologic agent of antibiotic-associated diarrhea. Infection with C. difficile (CDI) is characterized by diarrhea in clinical syndromes that vary from self-limited to mild or severe. Since its initial recognition as the causative agent of pseudomembranous colitis, C. difficile has spread around the world. CDI is one of the most common healthcare-associated infections and a significant cause of morbidity and mortality among older adult hospitalized patients...
