Understanding the immune response to Clostridioides difficile infection
Official title: CORE 1: The Clinical Data and Biospecimen Repository Core
Funded at Vanderbilt University Medical Center · NIH-11044215 · Data updated 2026-11-12
This study is looking at how your immune system responds to Clostridioides difficile infection (CDI) by collecting stool and blood samples from people diagnosed with CDI, so we can learn more and find better ways to treat and prevent it.

Who could benefit from this research
✓Could help
Ideal candidates for this research include individuals of all ages diagnosed with Clostridioides difficile infection.
✕Less likely to help
Patients who do not have Clostridioides difficile infection or those who are not willing to provide biospecimens may not benefit from this research.
What this research studies
This research focuses on Clostridioides difficile infection (CDI), a leading cause of antibiotic-associated diarrhea. It aims to evaluate the immune response to CDI by collecting patient biospecimens and clinical data from individuals diagnosed with the infection. Patients will be recruited from a large medical center, where trained personnel will gather stool samples and blood at various intervals after diagnosis. The goal is to enhance understanding of the immune response to CDI and improve future treatment and prevention strategies.
Why it matters
Potential benefit: If successful, this research could lead to better treatments and vaccines for Clostridioides difficile infection, reducing recurrence rates and improving patient outcomes.
How similar studies have gone: Previous research has shown promise in understanding immune responses to infections, but this specific approach to CDI is relatively novel.
