C Difficile

Progress made in the effort to develop new probiotics.

Scientific Reports - Combining a parsimonious mathematical model with infection data from tailor-made experiments to understand environmental transmission

Some probiotics may be beneficial in irritable bowel syndrome (IBS), but differences in species and strains used, as well as endpoints reported, have hampered attempts to make specific recommendations as to which should be preferred. We updated our previous meta-analysis examining this issue.

Lumen Bioscience's C diff therapy, LMN-201, combines four therapeutic proteins that act synergistically to neutralize both the C difficile bacterium and the toxin that causes its virulence directly in the patient’s gastrointestinal tract.

Clostridioides (formerly Clostridium) difficile is the most important infectious cause of antibiotic-associated diarrhea worldwide and a leading cause of healthcare-associated infection in the United States. The incidence of C. difficile infection (CDI) in children has increased, with 20 000 cases n …

C. difficile recurs in up to 20 percent of patients after treatment, and many of those patients die. Hence, new treatments are required.

The bacterium commonly referred to as C. diff is sometimes called “C-difficult” because it is so hard to treat, said Mohamed Seleem, director of the Center for One Health Research. Seleem and Nectagen Inc. have received a nearly $275,000 grant from the National Institute of Allergy and Infectious Diseases to study whether synthetic proteins developed by Nectagen can reduce the toxicity of the digestive bacteria.

Targeting the microbiome to improve outcomes in stem cell transplant

Disruption of the intestinal bacterial microbiota is frequently observed in the context of allogeneic hematopoietic cell transplantation (HCT) and is particularly pronounced in patients who develop graft-versus-host disease (GVHD). Donor fecal microbiota transplantation (FMT) restores gut microbial …

Dysbiosis of the gut microbiome is thought to be the developmental origins of the host's health and disease through the microbiota-gut-brain (MGB) axis: such as immune-mediated, metabolic, neurodegenerative, and neurodevelopmental diseases. Autism spectrum disorder (ASD) and attention-deficit/hypera …

The human microbiota is a complex ecosystem that colonizes body surfaces and interacts with host organ systems, especially the immune system. Since the composition of this ecosystem depends on a variety of internal and external factors, each individual harbors a unique set of microbes. These differe …

Objective Inflammatory bowel disease (IBD) is a multifactorial immune-mediated inflammatory disease of the intestine, comprising Crohn’s disease and ulcerative colitis. By characterising metabolites in faeces, combined with faecal metagenomics, host genetics and clinical characteristics, we aimed to unravel metabolic alterations in IBD.Design We measured 1684 different faecal metabolites and 8 short-chain and branched-chain fatty acids in stool samples of 424 patients with IBD and 255 non-IBD controls. Regression analyses were used to compare concentrations of metabolites between cases and controls and determine the relationship between metabolites and each participant’s lifestyle, clinical characteristics and gut microbiota composition. Moreover, genome-wide association analysis was conducted on faecal metabolite levels.Results We identified over 300 molecules that were differentially abundant in the faeces of patients with IBD. The ratio between a sphingolipid and L-urobilin could discriminate between IBD and non-IBD samples (AUC=0.85). We found changes in the bile acid pool in patients with dysbiotic microbial communities and a strong association between faecal metabolome and gut microbiota. For example, the abundance of Ruminococcus gnavus was positively associated with tryptamine levels. In addition, we found 158 associations between metabolites and dietary patterns, and polymorphisms near NAT2 strongly associated with coffee metabolism.Conclusion In this large-scale analysis, we identified alterations in the metabolome of patients with IBD that are independent of commonly overlooked confounders such as diet and surgical history. Considering the influence of the microbiome on faecal metabolites, our results pave the way for future interventions targeting intestinal inflammation.Data are available on reasonable request. Tables containing the levels of faecal metabolites and bacterial taxa abundances are provided with the manuscript.

Clostridioides difficile infection (CDI) is one of the most common diseases associated with medical care, having a more significant impact on patients with inflammatory bowel disease (IBD). The latest studies have proposed a change in management for CDI in IBD patients. This study aims to perform a systematic review that explores the risk factors associated with the infection and the most optimal approach in management. Multiple databases were used for this research, including PubMed, Google Scholar, Science Direct, and Cochrane Library. Studies published in the last five years in the English language were selected based on pre-established criteria. The quality assessment used was the Assessment of Multiple Systematic Review, the Newcastle-Ottawa Scale, and the Scale for the Assessment of Narrative Review Articles. Twelve studies met the inclusion criteria in this systematic review, including literature reviews, a case and control study, and systematic reviews and meta-analyses. Based on the findings in this research, we conclude that the treatment for an initial episode of CDI in IBD patients is the use of antibiotics, vancomycin, or fidaxomicin. For episodes of recurrent CDI (rCDI), fetal microbiota transplantation should be considered. The most common risk factors associated are gut microbiota disturbances, the use of antibiotics, and hospitalization. Due to a wide range of risk factors mentioned in some studies but disregarded in others, further research is needed to determine the most prevalent risk factors.
