Examining the link between gut bacteria and chronic graft-versus-host disease after stem cell transplantation

The Association of Microbiota Composition With Chronic Graft Versus Host Disease

First Affiliated Hospital of Zhejiang University · NCT05355675

This study is trying to see if the types of bacteria in the gut can help identify patients at risk for chronic graft-versus-host disease after they receive a stem cell transplant.

What this trial studies

This observational study investigates the relationship between microbiota composition and chronic graft-versus-host disease (cGVHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT). It aims to identify microbiome markers that could help in early detection of patients at high risk for cGVHD. Participants will provide blood and stool samples for analysis, including plasma banking and microbiome studies through DNA/RNA isolation and sequencing. The study is multicenter and nonrandomized, focusing on understanding how gut microbiota may influence post-transplant complications.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 to 65 who are scheduled to undergo allogeneic hematopoietic stem cell transplantation.

Not a fit: Patients outside the age range of 18 to 65 or those not undergoing allo-HSCT will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to personalized interventions that improve treatment outcomes and reduce the incidence of severe cGVHD in patients undergoing stem cell transplantation.

How similar studies have performed: While previous studies have explored the microbiome's role in transplantation outcomes, this specific approach focusing on cGVHD is relatively novel and under-researched.
