Evaluating gut microbiome in patients with POEMS syndrome and other plasma cell disorders

Gut Microbiome Studies in Patients With POEMS Syndrome and Other Plasma Cell Disorders

Observational Mayo Clinic · NCT06252948

This study looks at the gut bacteria in people with POEMS syndrome and other plasma cell disorders to see how it differs from healthy individuals and how it might change between active disease and remission.

What this trial studies

This observational study aims to investigate the characteristics and role of the gut microbiome in patients with POEMS syndrome and other plasma cell disorders, such as AL amyloidosis. Researchers will analyze stool samples from newly diagnosed POEMS patients and compare them with samples from patients with other plasma cell disorders and healthy controls. The study will also examine differences in gut microbiome signatures between active disease and remission in POEMS patients. The goal is to enhance understanding of the relationship between gut microbiome and these rare disorders.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with POEMS syndrome, AL amyloidosis, multiple myeloma, or monoclonal gammopathy of undetermined significance.

Not a fit: Patients under 18 years, pregnant individuals, or those with chronic gastrointestinal disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the gut microbiome's role in plasma cell disorders, potentially leading to new therapeutic strategies.

How similar studies have performed: While the specific focus on gut microbiome in POEMS syndrome is novel, similar studies in other conditions have shown promising results.
