Investigating gut bacteria changes during stem cell transplant

Intestinal Microbiota Alteration by Antibiotics Used During Stem Cell Transplant Admission

Observational Henry Ford Health System · NCT04623424

This study is trying to see how antibiotics used during stem cell transplants affect gut bacteria and whether these changes influence complications like graft-versus-host disease and relapse rates in patients.

What this trial studies

This observational study aims to explore how antibiotic use during stem cell transplant admissions affects the composition of intestinal microbiota over time. By collecting stool samples from patients at various stages of the transplant process, researchers will analyze the relationship between antibiotic regimens and changes in gut bacteria. The study focuses on understanding the potential impact of these changes on complications such as acute graft-versus-host disease (aGVHD) and relapse rates. This research could provide insights into optimizing antibiotic use to improve transplant outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 18-80 undergoing allogenic or autologous stem cell transplants for malignant hematological conditions or bone marrow failure.

Not a fit: Patients who are not undergoing stem cell transplants or those outside the age range of 18-80 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management of antibiotic use during stem cell transplants, potentially reducing complications and enhancing patient recovery.

How similar studies have performed: While there is emerging evidence regarding the impact of intestinal microbiota on transplant outcomes, this specific approach to studying antibiotic effects on microbiota during stem cell transplants is relatively novel.
