Abstract

Clostridium difficile (C. difficile) is the most frequent cause of nosocomial antibiotic-associated diarrhea. The incidence of C. difficile infection (CDI) has been rising worldwide with subsequent increases in morbidity, mortality and health care costs. Asymptomatic colonization with C. difficile is common and a high prevalence has been found in specific cohorts, e.g. hospitalized patients, adults in nursing homes and in infants. However, the risk of infection with C. difficile differs significantly between these cohorts. While CDI is a clear indication for therapy, colonization with C. difficile is not believed to be a direct precursor for CDI and therefore does not require treatment. Antibiotic therapy causes alterations of the intestinal microbial composition, enabling C. difficile colonization and consecutive toxin production leading to disruption of the colonic epithelial cells. Clinical symptoms of CDI range from mild diarrhea to potentially life-threatening conditions like pseudomembranous colitis or toxic megacolon. While antibiotics are the still the treatment of choice for CDI, new therapies have emerged in recent years such as antibodies against C. difficile toxin B and fecal microbial transfer (FMT). This specific therapy for CDI underscores the role of the indigenous bacterial composition in the prevention of the disease in healthy individuals and its role in the pathogenesis after alteration by antibiotic treatment. In addition to the pathogenesis of CDI, this review focuses on the colonization of C. difficile in the human gut and factors promoting CDI.

  • Clostridioides difficile can be carried asymptomatically throughout life, and only cause problems in older age when the host is immunocompromised and treated with antibiotics.

    “Clostridioides difficile can be carried asymptomatically throughout life, and only cause problems in older age when the host is immunocompromised and treated with antibiotics 19 .”

    From Human microbiome myths and misconceptions (2023) · cites this paper as [19]

    The Asymptomatic Colonization section reports symptom-free carriage in infants and adults, while Extrinsic Risk Factors > Age says infection is more common and more severe in older people and discusses immune responses and antibiotic use as possible contributors (page numbers unavailable). The paper does not establish that an individual carries C. difficile throughout life or that illness occurs only in older, immunocompromised people treated with antibiotics; its Epidemiology of CDI section also reports infection in infants.

  • It is not evidence-based to conclude that a characteristic 'pathobiome' has a role in most diseases.

    “It is, therefore, a leap that is not yet evidence-based to conclude that a characteristic 'pathobiome' has a role in most diseases.”

    From Human microbiome myths and misconceptions (2023) · cites this paper as [19]

    The Host Factors section discusses how changes in intestinal microbiota can favor C. difficile infection, and the Conclusion says the progression from colonization to infection is not completely understood. Neither passage addresses whether evidence supports a characteristic pathobiome in most diseases. Searches for “pathobiome most diseases” and for a characteristic disease-associated microbial community found no passage making that broader assessment. (LLM, conf=0.73)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
