Active clinical trials for "Clostridium Infections"

The goal of this research is to compare alterations of gut microbiota and fecal metabolomics alterations between inflammatory bowel disease patients infected with or without Clostridioides difficile. The main questions it aim to answer are: which bacterial genus or fecal metabolites can discriminate IBD patients infected or more likely to be infected with Clostridioides difficile and their role in the pathogenesis of Clostridioides difficile. type of study: observational study participant population/health conditions population diagnosed with Ulcerative colitis or Crohn's disease Having diarrhea Participants will be included in this research. If there is a comparison group: Researchers will compare healthy people without IBD or any diarrhea to see if disease or diarrhea would affect the gut microbiota and metabolites.

The purpose of this study is to determine whether a single strain capsulated probiotic, when used after standard C. difficile antibiotic therapy, is effective in reducing the risk of infection recurrence mediated by a decrease in colonization by toxigenic C. difficile. This study will include adults with a history of two episodes of C. difficile infection (CDI).

To establish optimal dosing of lyophilized Fecal microbiota transplantation (FMT) product in the treatment of recurrent C. difficile infection

Study to evaluate the safety of ridinilazole in adolescent subjects and how ridinilazole is metabolized.

The primary purpose of this study is to compare the clinical outcomes of cure and recurrence of Clostridium difficile infection in spinal cord injured patients who are treated with oral Fidaxomicin vs. oral Vancomycin. The secondary aim of this study is to compare the overall costs of treatment of Clostridium difficile infection in the two study groups.

Clostridium difficile (C. difficile) can cause symptoms ranging from mild diarrhea to life-threatening colitis. Illness from C. difficile most commonly affects patients in hospitals and long-term care facilities and typically occurs after a patient has received antibiotics. In vitro data indicate Calcium Aluminosilicate Anti-Diarrheal (CASAD) has the potential to bind TNFα, IL-1, IL-6, and IL-10 in the intestines and, therefore, may act to reduce severity of fever, leukocytosis, and bowel injury in patients with C. difficile infection. This would likely occur in conjunction with neutralization of C. difficile toxins A&B by CASAD. Computer modeling of CASAD performed by Phillips et al. at Texas A&M University supports this hypothesis. The investigators hypothesize that adding CASAD 1.5 grams po tid to any standard-of-care therapy will reduce the duration and severity of diarrhea and other symptoms in patients with C. difficile infection.

Clostridium difficile has become one of the leading causes of hospital acquired infections, and is associated with increased mortality. Patients with C. difficile associated disease (CDAD) possess deficiencies in 'normal' fecal microbial composition, most likely as a result of earlier antibiotic usage. The current standard of care treatment for severe C. difficile, which consists of antibiotics, does not restore the microbiota. Restoration of the normal colonic microbiota by fecal microbiota transplantation (FMT) may enable reversion colonic microbial population to a more 'normal'state and lead to cure. A few patients develop severe CDAD which may be complicated by adynamic ileus, or toxic megacolon. The management in this context is based on limited data, and for some the only available option is sub-total colectomy. Although FMT is by no means a new therapeutic modality, there is limited information on its use for the treatment of acute CDAD, including severe CDAD. Because of the high morbidity and mortality associated with treatment of patients with severe CDAD, and because the evidence supporting the current recommendations is weak and based upon the demonstration that FMT is an effective strategy to re-establish a balanced intestinal microbiota with resultant cure of recurrent CDAD, we propose to study the efficacy and safety of FMT for severe CDAD. Patients with severe CDAD can be divided into two operational groups; those that have diarrhea and those that suffer from adynamic ileus. We propose to apply FMT through colonoscopy for all patients because current data suggest that the overall success rate of FMT for recurrent CDAD with lower gastrointestinal tract FMT was higher than FMT through the upper gastrointestinal tract. In addition, for patients with adynamic ileus and toxic megacolon (i.e., the population with the highest CDAD-associated morbidity and mortality), intra-colonic FMT administration is the preferred alternative.

Approximately 65 patients will be entered into this study taking place in North America. The aim of this study is to evaluate the safety, efficacy and absorption of an investigational drug in patients with C. difficile-associated diarrhea (CDAD). All study related care is provided including doctor visits, physical exams, laboratory tests and study medication. Total length of participation is 6 weeks.

The overarching objective of this study is to address the knowledge gap regarding the short-term and long-term safety of fecal microbiota transplants (FMT). The design will be a prospective, open-label, multi-center longitudinal cohort study to assess the short- and long-term safety of FMT as well as the clinical resolution of diarrhea among 150 patients with 3 or more episodes of clostridium difficile infection (CDI defined as 3 unformed stools over 24 hours for 2 consecutive days and either a positive stool test for CDI or pseudomembranes on colonoscopy/sigmoidoscopy). Subjects will be adult outpatients referred to one of the study centers after at least three recurrent episodes of CDI and previous treatment with at least one 10-day course of oral vancomycin or fidaxomicin. After FMT by colonoscopy/sigmoidoscopy or enema, patients will be followed prospectively and monitored for clinical resolution and adverse events at: 3 days (telephone), 3 weeks (clinical assessment), 8 weeks (telephone), 6 months (telephone), and 12 months (telephone) after FMT. Subjects who recur will be offered a second FMT by colonoscopy with a different donor. Microbiome analysis will be conducted from stool samples at baseline and each of the 5 follow-up intervals.

The primary objective is to compare fidaxomicin versus vancomycin for the sustained clinical cure of Clostridium difficile Infection (CDI) in adult patients receiving immunosuppressive therapy.
