C Diff Diagnosis

Introduction. Infectious gastroenteritis is a common reason for consulting a physician. Although most cases of gastrointestinal illness are self-limiting, the identification of the etiologic pathogen by stool specimen analysis is important in cases of more severe illness and for epidemiologic …

The utilization of GI PCR panels in AGE patients has revolutionized the field of diagnostics by providing rapid and accurate identification of pathogens. In units without the possibility of GI PCR testing, CRP, procalcitonin, CRP/albumin ratio and procalcitonin/albumin ratio may be useful in the dec …

This study explored the novel application of the RTCA assay in effectively discerning clinical CDI from CDC cases.

Clostridioides difficile represents a major burden to public health. As a well-known nosocomial pathogen whose occurrence is highly associated with antibiotic treatment, most examined C. difficile strains originated from clinical specimen and were isolated under selective conditions em …

Nosocomial-associated diarrhea due to Clostridioides difficile infection (CDI) is diagnosed after sample precultivation by the detection of the toxins in enzyme immunoassays or via toxin gene nucleic acid amplification. Rapid and direct diagnosis is important for targeted treatment to prevent …

Microscopic technologies including light and fluorescent, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and cryo-electron microscopy have been widely utilized to visualize Clostridioides difficile at the molecular, cellular, community, and structural biology level. This …

For many patients with C diff, the experience of medical gaslighting is a common one because many health care providers lack education and familiarity with the disease.

Acute gastroenteritis (AGE) is a leading cause of morbidity and mortality worldwide across all age groups that disproportionally affects young children in low- and middle-income countries and immunocompromised patients in high-income countries. Regional outbreaks of AGE are typically detected by tra …

This study explored the novel application of the RTCA assay in effectively discerning clinical CDI from CDC cases.

Use of this 2-step algorithm likely results in underreporting of some NAAT+/toxin- cases with clinically relevant CDI. Disease severity and laboratory interpretive comments influence treatment decisions for NAAT+/toxin- cases.

Clostridioides difficile (C. diff) is a leading cause of diarrhea and healthcare-associated infections in the United States and recognized as an urgent threat by the Centers for Disease Control. Virulence of C. diff infections is believed to rely primarily on the production of two toxins: TcdA and TcdB. TcdA and TcdB are large homologous proteins...

The major virulence factors of Clostridioides difficile (C. difficile) are enterotoxins A (TcdA) and B (TcdB). The study of toxins is a crucial step in exploring the virulence of this pathogen. Currently, the toxin purification process is either laborious and time-consuming in C. di …

Clostridioides difficile is the leading cause of antibiotic-associated diarrhea and pseudomembranous colitis in adults. Various C. difficile strains circulate currently, associated with different outcomes and antibiotic resistance profiles. However, most studies still focus on the reference strain 6 …

In both study periods, most C. difficile isolates were not closely related, suggesting varied sources of acquisition and that spread of C. difficile within the hospital was unlikely. Current infection control precautions may therefore warrant review. Underlying risk factors for CDI wer …

Clostridioides difficile is the most common anaerobic bacterium that causes healthcare-associated infections, and prompt diagnosis and infection control are important because it causes C. difficile infection (CDI). In this evaluation, the C. difficile nucleic acid detection reagent, Sm …

Accurately diagnosing Clostridioides difficile infection (CDI) is crucial for effective patient management. A misdiagnosis poses risks to patients, leads to treatment delays, and contributes to infection transmission in healthcare settings. While using polymerase chain reaction (PCR) to ampli …

Diagnosis of Clostridioides difficile infection (CDI) can be challenging. First of all, there has been debate on which of the two reference assays, cell cytotoxicity neutralization assay (CCNA) or toxigenic culture (TC), should be considered the gold standard for CDI detection. Although the CCNA suf …

Clostridium difficile (Clostridioides difficile) is a leading cause of nosocomial infections in hospitalized patients worldwide. Stool samples were collected from 112 inpatients admitted to different hospitals and were screened for C. difficile GDH + toxin A + B by immunoassay, …

Scientific Reports - An integrated pipeline for prediction of Clostridioides difficile infection

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 of NAAT results between fresh …

Accurately diagnosing Clostridioides difficile infection (CDI) is crucial for effective patient management. A misdiagnosis poses risks to patients, leads to treatment delays, and contributes to ...

Bacteremia is a rare finding among Clostridioides difficile infections. We describe a case of a 67-year-old man with resected colorectal cancer with colostomy who presented with small bowel obstruction and was admitted for lysis of adhesions. On day 8 of admission, he developed leukocytosis a …

A retrospective cohort study of inpatient encounters from 3 hospitals in the Duke University Health System showed greater rates of testing among White patients compared to Black and NWNB patients.

White patients received more C. difficile tests than Black and NWNB patient groups when controlling for race patient days. Future studies should control for comorbidities and investigate community onset of C. difficile by race and ethnicity.

Screening for Clostridioides difficile in all admissions to ICU identified asymptomatic carriers and their risk for developing and/or transmitting infection.

Based on the results of this study, we conclude that the PCR technique is the only reliable method for the diagnosis of this pathogen.

Paediatric diarrhoea patients showed higher positivity rates than adult patients. Application of FAGIP for acute diarrhoea might lower unnecessary antimicrobial use.

Our study highlights the dominance of Toxin EIA-negative CDI specimens in a clinical setting and the high frequency of known virulent ribotypes in these specimens. Therefore, a careful reevaluation of the clinical relevance of diagnostically-discrepant specimens particularly in the context of missed …
