Investigating gut microbiota and immune function in monoclonal gammopathy patients

Correlation Analysis of Intestinal Flora and Immune Function in Patients With Monoclonal Immunoglobulinaemia Co-infection

Observational Zhujiang Hospital · NCT06539832

This study looks at the gut bacteria and immune system in patients with monoclonal gammopathy to see how they might be affected, especially in those with infections.

What this trial studies

This observational study examines the gut microbiota characteristics and immune function in patients diagnosed with monoclonal gammopathy, particularly those with concurrent infections. It includes 200 patients, split evenly between those with infections and those without, alongside 100 healthy controls matched for age and gender. By analyzing the composition of gut microbiota and immune markers, the study aims to uncover correlations between microbiome alterations and immune dysfunction, providing insights into the underlying mechanisms affecting these patients.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 45 and older diagnosed with monoclonal gammopathy who do not exhibit symptoms of infection.

Not a fit: Patients with a history of intestinal tumors, inflammatory bowel disease, or those currently on antibiotic therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of how gut health influences immune function in monoclonal gammopathy patients, potentially leading to improved management strategies.

How similar studies have performed: While the specific approach of correlating gut microbiota with immune function in monoclonal gammopathy is novel, similar studies in other conditions have shown promising results.
