Fecal microbiota transplantation (FMT) achieves the purpose of treating intestinal and extra-intestinal diseases by transplanting the functional microbes in the feces of healthy people into the patient's intestine through the upper or lower alimentary tract routes to rebuild the patient's intestinal microbiota. Recently, FMT has been widely used in the treatment of various gastrointestinal diseases, including but not limit in CDI. In this study, we focused on the demonstration of FMT action mechanism in CDI treatment.
Data on the seroprevalence of antibodies to Clostridioides difficile surface proteins and toxins are scarce. In 1983, Viscidi et al. showed that antibodies to C. difficile toxins A and B were detected in 60 to 70% of an adult population. Two-thirds of the adults tested had a serological trace, probably linked to a previous encounter with C. difficile. One of the hypotheses raised would be that exposure to this pathogen occurs very early and regularly throughout our lives. Indeed, in this study, antibodies to C. difficile toxins were detected from early childhood and persisted over time even after 60 years. The antibody response did not appear to vary with age or terrain. However, these results were only qualitative and did not allow for inter-individual variations due to the limitations of the techniques used at the time. Finally, in this work, it was important to underline that the neutralizing character of the cytotoxic effect of toxins on cell culture was not observed in all patients. Since this seminal work, several studies have shown that the host immune response plays a central role in the pathophysiology of C. difficile infections (CDI). In 2000, Kyne et al. showed that after colonization with a toxigenic C. difficile strain, patients with asymptomatic carriage had significantly higher serum levels of IgG directed against toxin A than patients who developed disease. Subsequently, they also showed in 2001 that a serum response directed against toxin A after a first episode of CDI was associated with less recurrence. Finally, Leav et al. showed in 2010 that a serum response directed against C. difficile toxin B was also associated with protection against recurrent forms. Several studies have also suggested that the host immune response, this time directed against colonization factors, could also play a major role in the evolution and prognosis of CDI. In a previous study, investigators showed a significant difference in the level of anti-SlpA antibodies (S-layer component) between CDI patients and control patients. At the same time, the epidemiology of CDI has changed since 2003 due to the emergence of a new epidemic and hypervirulent strain (PCR ribotype 027) producing a third toxin, the binary toxin. The humoral response to this toxin remains poorly described to date. On the basis of these numerous studies, new therapeutic immunization strategies (active or passive) aimed at neutralizing the action of C. difficile toxins and colonization factors have been or are being developed. However, it remains to identify the patients likely to benefit from these innovative strategies. This was the main objective of the SERODIFF study (currently being finalized), which identified certain patient profiles in which no seroconversion or isotype class switching of antibodies was observed following CDI. The absence of neutralizing antibody production would seem to correlate with recurrent forms. Thus, these patients would be those who could be eligible for a passive immunization strategy such as the administration of anti-toxin B monoclonal antibodies, bezlotoxumab, recently marketed in France. In this study, investigators aim to evaluate the seroprevalence stratified by age group, sex and by the main risk factors for CDI. Furthermore, the neutralizing and protective effect of the detected antibodies against C. difficile virulence factors will be studied.
The purpose of this study is to assess the feasibility of TrueLoo™, an Internet-connected smart toilet seat, in accurately monitoring and logging bowel movements and urinations of residents in senior living facilities across Northern California.
Clostridioides difficile infection (CDI) is one of the most common hospital-acquired infectious diseases with a high mortality rate (6-30%). The treatment of CDI, especially the recurrent form of the disease is still considered a challenge. The FILTRATE randomized controlled trial aims to investigate the safety and efficacy of fecal filtrate transplantation in the treatment of recurrent CDI and compare it with conventional fecal microbiota transplantation (FMT).
The primary objective of the study is to determine whether dietary intervention to increase fiber and decrease fat reduces C. difficile infection recurrence in a cohort of oncology patients.
Clostridioides difficile (CD) infection (CDI) is a global health threat with an urgent need for new treatment strategies. Faecal microbiota transplantation (FMT) is effective for recurrent Clostridioides difficile infection (CDI), and is currently recommended for multiple (three or more), recurrent CDI infections. The role of FMT earlier in the treatment hierarchy of CDI remains to be determined. In this randomized, double-blinded, placebo-controlled clinical trial, we compare FMT with placebo following standard antibiotic treatment for first or second Clostridioides difficile infection.
Aim: To investigate if host factors, such as composition and diversity of intestinal microbiota and/or genetic determinants, are associated with a higher risk of recurrence of Clostridioides difficile infection (CDI). To generate a predictive tool based on epidemiological, clinical, genetic and microbiologic variables aimed to identify patients at a higher risk of CDI recurrence in a context of optimized ICD management. Design: Multicenter prospective cohort study. Patients: Older than 18 years patients with CDI diagnosis, made by IDSA criteria, in the participant centers. Follow-up: A stewarship program aimed to improve CDI management, including early detection of CDI recurrence, will be implemented in the participant centers. Blood samples for genetic testing and stool samples for intestinal microbiome studies will be collected. Variables and data analysis: The primary outcome variable will be the emergence of CDI recurrence. Potential independent predictors of recurrence, including genetic and microbiological factors, will be assessed. A predictive tool based on independent predictors of recurrence will be built in a development subpopulation. The performance of the model will be assessed by ROC curves, and sensititvity, especificity, as well as negative and positive predictive values will be calculated, both in the development subpopulation and in a validation subset.
This is a prospective, clinical, multicentre study aimed to collect biological samples and study microbiota from subjects with Clostridium Difficile (CDI), subjects affected by Multi Drug Resistant Organisms (MDRO) infection, subjects with Chronic Inflammatory Bowel Disease (IBD), subjects with Irritable Bowel Syndrome (IBS), subjects with Hepatic Encephalopathy and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological) The study will allow to: - Provide biological samples (faeces, saliva, blood, urine) from healthy volunteers and patients to the first Italian microbiota biobank; - Study microorganisms using different in vitro and in vivo techniques; - Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.
Our objective of this study is to derive a real incidence of CDI in tertiary hospitals located through Korean peninsula. In order to get a close value to the truth, the study is planned to co-perform with a national study which was proposed in evaluation process to include more hospitals. Along with the incidence of CDI, clinical characteristics and outcome of CDI will be examined and microbiologic characteristics of C. difficile isolates from CDI patients are studied.
