C Diff Diagnosis

Improving Early Detection of Clostridioides difficile Infections Through Electronic Reports

MGPP testing is most useful when administered at hospital admission or as an outpatient. Since MGPP is sensitive and does not distinguish between colonization and causes of diarrhea, caution is needed in interpretation of results, especially for toxin negative C. difficile and diarrheagenic gram-neg …

A group of bacterial proteases, the Pro-Pro endopeptidases (PPEPs), possess the unique ability to hydrolyze proline-proline bonds in proteins. Since a protease's function is largely determined by its substrate specificity, methods that can extensively characterize substrate specificity are valuable …

Reflex testing for a laboratory diagnosis of CDI results in rapid, systemwide decreases in the rate of HO-CDI. Additional research is needed to distinguish CDI from C difficile colonization in patients with discordant testing.

The pilW_4-plex PCR assay is an accurate and rapid method with high sensitivity and specificity for identification of ST1 and detection of toxigenic C. difficile in stool.

Our data highlight the protective role of IL-13 in protecting from more severe CDI and the association of poor responses with a dysregulated monocyte-macrophage compartment. These results increase our understanding of type 2 immunity in CDI and may have implications for treating disease in patients.

Clostridioides difficile infection (CDI) is the leading cause of healthcare-associated diarrhea, resulting in high morbidity, mortality, and economic burden. In clinical laboratories, CDI testing is currently performed on stool samples collected from patients with diarrhea. However, the diagn …

Clostridioides difficile (C. difficile) is the most common agent of antibiotic-associated diarrhea, leading to intestinal infection through the secretion of two major toxins. Not all strains of this bacterium are toxigenic, but some of them cause infection via their accessory virulence factors, such …

Allowing bedside nurses the autonomy to order testing for clostridium difficile results in faster turnaround times, researchers report.

To overcome the deficiencies of conventional methods, the potential of advanced methods for C. difficile diagnosis, their direction, perspective, and challenges ahead were discussed.

Download scientific diagram | Changes in Clostridioides difficile tests and CDI cases from January 2015 to March 2018, divided into quarters, with the dotted line indicating 2016 quarter 1 as the intervention period. (A) C. difficile test volumes for inpatients. (B) Reported HO-CDI rates. (C) Distribution of diarrheal episodes among LabID HO-CDI events. (D) Laxative use among LabID HO-CDI events. (E) Laxative use among LabID HO-CDI events with clinically significant diarrhea, defined as ≥3 unformed stools within 24 h prior to testing. (F) Numbers of reported HO-CDI events and true HO-CDI events, after removal of events with laxative use and/or insignificant diarrhea (

ML models show promise in predicting CDI incidence and outcomes. However, the observed heterogeneity in CDI definitions and the lack of real-world validation highlight challenges in clinical implementation. Future research should focus on external validation and the use of standardized definitions a …

A study presented at the Society for Healthcare Epidemiology of America (SHEA) conference evaluated adherence to laxative administration guidelines before CDI testing in Veteran Affairs (VA) hospitals and explored associated demographic and contextual factors.

To overcome the deficiencies of conventional methods, the potential of advanced methods for C. difficile diagnosis, their direction, perspective, and challenges ahead were discussed.

The diagnosis and treatment of C. difficile infection in pediatrics remain challenging and recommendations lag behind advances made in the adult field. Recent data suggests that use of fidaxomicin both as treatment of first episode or recurrences may be beneficial in pediatrics just as in adu …

Recent studies of an ultrasensitive C. difficile toxin protein assay suggest that toxin protein assays will never be able to differentiate CDI from carriage.

Nucleic acid amplification tests (NAATs) are frequently used in Clostridioides difficile research and diagnostic testing, but the effect of freezing specimens on C. difficile NAAT performance is not well characterized. This study evaluated the concordance ...

This study underscores the importance of a joint effort towards standardized surveillance practices in providing comprehensive insights into C. difficile infection epidemiology and effective prevention strategies in Swiss healthcare settings. The patient-related approach remains the gold standard fo …

Early identification of acute gastroenteritis (AGE) pathogens via PCR may improve the management of patients presenting to the emergency department (ED). In this study, we evaluated the implementation of a testing algorithm for ED patients with AGE using the BD MAX automated PCR system. Data from 13 …

Clostridioides difficile is a main cause of diarrheic infections after antibiotic treatment with serious morbidity and mortality worldwide. Research on this pathogen and its virulence has focused on bacterial isolation from clinical specimens under ...

Clostridioides difficile is a well-recognized healthcare-associated pathogen, with its significance widely recognized in adult populations. Despite this, there is limited data on the significance of detection within paediatric populations, both for individual patient management and wider tran …

Clostridioides difficileinfection (CDI) is the leading cause of hospital-acquired infective diarrhea. Current methods for diagnosing CDI have limitations; enzyme immunoassays for toxin have low sensitivity andClostridioides difficilePCR cannot differentiate infection from colonization. …

Northwestern Medicine developed a testing strategy using a two-step algorithm to improve diagnostic accuracy and treatment outcomes.

Clostridioides difficile, a gram-positive anaerobic bacterium, is one of the most frequent causes of nosocomial infections. C. difficile infection (CDI) results in almost a half a million infections and approximately 30,000 deaths in the U.S. each year. Broad-spectrum antibacterial use is a strong r …
