Tea and Recurrent Clostridium difficile Infection
Background and Aims. Studies have shown effects of diet on gut microbiota. We aimed to identify foods associated with recurrent Clostridium difficile infection (CDI). Methods. In this cross-sectional survey, consecutive patients diagnosed with CDI were identified by electronic medical records. Colitis symptoms and positive Clostridium difficile assay were confirmed. Health-care onset-health-car...
متن کاملVaccination against Clostridium difficile using toxin fragments
Clostridium difficile is a major cause of antibiotic associated diarrhea. Recently, we have shown that effective protection can be mediated in hamsters through the inclusion of specific recombinant fragments from toxin A and B in a systemically delivered vaccine. Interestingly while neutralizing antibodies to the binding domains of both toxin A and B are moderately protective, enhanced survival...
متن کاملClostridium difficile toxin A induces a specific antisecretory factor which protects against intestinal mucosal damage.
Peroral challenge with toxin A from Clostridium difficile induced the formation of antisecretory factor in rats. The animals were given 100 micrograms of the toxin, which was followed by a pronounced diarrhoea and by the appearance of antisecretory factor in the pituitary gland. In electrofocusing, the induced antisecretory factor separated in two peaks (pI 5.4 and 5.0); both fractions showed a...
متن کاملTreatment Strategies for Recurrent Clostridium difficile Infection.
BACKGROUND Recurrent Clostridium difficile infection represents a major clinical challenge. Treatment is often based on empiric selection from relatively few options supported by limited clinical evidence. OBJECTIVE To review and evaluate the literature on therapeutic alternatives for recurrent C. difficile infection. DATA SOURCES The MEDLINE, PubMed, Embase, and Cochrane databases were sea...
متن کاملIntraluminal Administration of Resiniferatoxin Protects against Clostridium difficile Toxin A-Induced Colitis
Clostridium difficile toxin A is a colonic inflammatory agent that acts partially by activation of TRPV1 (transient receptor potential vanilloid type 1). Resiniferatoxin (RTX) is an excitotoxin that activates TRPV1 at low concentrations and defunctionalizes TRPV1 at high concentrations. RTX at various doses was injected intraluminally into isolated ileal segments in anesthetized rats. After 3 h...
