Six of fifteen quinoline-based derivatives demonstrated comparable low micromolar inhibitory effects on human cytosine methyltransferase DNMT1, and the bacterial adenine methyltransferases Clostridioides difficile CamA and Caulobacter crescentus CcrM. Compounds 9 and 11 w …

Asymptomatic bacteriuria is frequently encountered in clinical practice and should be treated only in pregnant women and before invasive urological procedures. Inappropriate treatment of asymptomatic bacteriuria is associated with numerous adverse effects including allergic reactions, increased anti …

The first British Society of Gastroenterology (BSG) and Healthcare Infection Society (HIS)-endorsed faecal microbiota transplant (FMT) guidelines were published in 2018. Over the past 5 years, there has been considerable growth in the evidence base (including publication of outcomes from large natio …

We observed disease resolution post IVIg therapy in over 50% of patients with refractory CDI. Our data also support a potential enhanced effect of IVIg in immunosuppressed individuals. Thus, the role of IVIg for CDI treatment, particularly in the immunosuppressed, warrants future case-control studie …

Growing evidence demonstrates the key role of the gut microbiota in human health and disease. The recent success of microbiotherapy products to treat recurrent Clostridioides difficile infection has shed light on its potential in conditions associated with gut dysbiosis, such as acute graft-v …

Since the emergence of SARS-CoV-2 in late 2019, the global mortality attributable to COVID-19 has reached 6,972,152 deaths according to the World Health Organization (WHO). The association between coinfection with Clostridioides difficile (CDI) and SARS-CoV-2 has limited data in the literatur …

Vancomycin (VAN) and metronidazole (MTR) remain the current drugs of choice for the treatment of non-severe Clostridioides difficile infection (CDI); however, while their co-administration has appeared in clinical treatment, the efficacy varies greatly and the mechanism is unknown. In this st …

Clostridioides difficile colitis is an important source of hospital-acquired diarrhea associated with antibiotic use. Symptoms are profuse watery diarrhea, typically following a course of antibiotics; however, some cases of fulminant disease may manifest with shock, ileus, or megacolon. Nonfulminant …

The gut microbiome is defined as the microorganisms that reside within the gastrointestinal tract and produce a variety of metabolites that impact human health. These microbes play an intricate role in human health, and an imbalance in the gut microbiome, termed gut dysbiosis, has been implicated in …

Fecal microbiota transplantation (FMT) is effective against recurrent Clostridioides difficile infection (rCDI), but its safety is jeopardized by the potential transmission of pathogens, so international guidelines recommend either a quarantine or a direct stool testing. Whereas reports of the quara …

Our objective was to update a clinical practice guideline for the prevention and treatment of Clostridioides difficile infection (CDI) in pediatric patients with cancer and hematopoietic cell transplantation recipients. We reconvened an international multi-disciplinary panel. A systematic rev …

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 …

Considering patient room shortages and prevalence of other communicable diseases, reassessing the isolation of patients with Clostridioides difficile infection (CDI) is imperative. We conducted a retrospective study to investigate the secondary CDI transmission rate in a hospital in South Korea, whe …

Our study demonstrates that toxin EIA-negative patients had milder laboratory findings and no complications, despite not receiving treatment. Prolonged hospitalisation and exposure to high-risk antibiotics could potentially serve as markers for the development of toxin EIA-positive CDI.

Clostridioides difficile infections (CDIs) continue to be a persistent healthcare concern despite newer antibiotic treatments, enhanced infection control practices, and preventive strategies focused on restoring the protective intestinal microbial barrier. Recent strides in gene sequencing re …

Our results suggest that for moxifloxacin, tetracycline and clindamycin, phenotypic resistance in C. difficile can be predicted by genetic indicators and used for public health purposes. However, for the other five antibiotics, the model is not accurate and further development is necessary.

Understanding the potential antimicrobial properties of natural compounds and their impacts on Clostridioides difficile virulence factors may aid in developing alternative strategies for preventing and treating C. difficile infections (CDI). In this study, we investigated the bacterici …

In this series of over 5,500 patients who had a rPCNA undergoing primary TJA, perioperative prophylaxis with cefazolin resulted in a 0.1% incidence of allergic reactions that were clinically indolent. Cefazolin can be safely administered to most patients, independent of rPCNA severity.

Fecal microbiota transplantation for recurrent C. difficile infection can be the best therapeutic option in severely immunocompromised patients depending on a case-by-case assessment of the benefit/risk ratio

Clostridioides difficile infection (CDI) is responsible for around 300,000 hospitalizations yearly in the United States, with the associated monetary cost being billions of dollars. Gut microbiome dysbiosis is known to be important to CDI. To the best of our knowledge, metatranscriptomics (MT …

A study presented at the Society for Healthcare Epidemiology of America (SHEA) conference assesses the link between antibiotic use and C difficile infection in Tennessee.

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

The long-term health care burden after Clostridium difficile (C diff) infection (CDI) is great for elderly patients. But even nonelderly patients are at risk for gastrointestinal symptoms for up to 2 years afterward.

Although no longer indicated as a first-line therapy, metronidazole still has therapeutic benefits and can serve patients in certain settings and circumstances.

Laura Gillespie, PharmD, discusses the impact of pharmacist-led initiatives on health care–associated C diff rates for health care systems.

Download scientific diagram | E-cadherin of IECs interacts with increasing C. difficile spores in TcdA- and TcdB-intoxicated cells. Differentiated Caco-2 cells were intoxicated with TcdA and TcdB for 8 h at 37°C in DMEM without serum. As a control, cells were incubated with DMEM without serum. Then, cells were infected with C. difficile spores for 1 h at 37°C. Nonpermeabilized cells were stained for accessible E-cadherin (shown as acc Ecad; green), spores (red), and nuclei (blue). (A) Representative 3D projection confocal micrograph of healthy cells infected with C. difficile spores (Ctrl). (A, Right) Magnifications of representative C. difficile spores associated or not with E-cadherin. (B and C) Plot profiles of fluorescence intensity of C. difficile spores (red line) and accessible E-cadherin (shown as Ecad, green line) performed in the white line of panel A.

Repartition of spores that were positive (Ecad+) or negative (Ecad−) associated with fluorescence signal for accessible E-cadherin was shown as the average associated/nonassociated spores with E-cadherin for each field; a total of ~500 spores were analyzed. Fluorophores were digitally reassigned for a better representation. Micrographs are representative of 6 independent fields of 3 different experiments. Error bars indicate mean ± SEM.

Our approach provides new opportunities to rationally harness live gut probiotic strains and metabolites to reduce intestinal inflammation, restore gut microbial composition, and expedite the development of safe and effective treatments for IBD.

Beneficial gut bacteria are indispensable for developing colonic mucus and fully establishing its protective function against intestinal microorganisms. Low-fiber diet consumption alters the gut bacterial configuration and disturbs this microbe-mucus interaction, but the specific bacteria and microb …

WMT demonstrated therapeutic efficacy in CD treatment, likely due to the effective reconstruction of the patient's microbiome. Multi-omics techniques can effectively help decipher the potential mechanisms of WMT in treating CD.
