Characteristics and Clinical Significance of Gut Microbiota in Patients With Monoclonal Gammopathy

This is an observational case-control study, aiming to systematically analyze the gut microbiome characteristics of patients with monoclonal gammopathy of undetermined significance (MGUS). The study will collect blood and stool samples from MGUS patients, non-MGUS patients (with similar diseases), and healthy controls, and perform multi-omics detection including microbiomics, peptidomics, and biochemical immunology. It will comprehensively analyze the abnormal features of the gut microbiome in MGUS patients, which may help provide new biomarkers and potential mechanisms for the diagnosis, prognosis evaluation, and treatment strategies of MGUS.

Intestinal Flora and Immunity in Monoclonal Gammopathy Patients

This study aims to investigate the characteristics of the gut microbiota and immune function status in patients with monoclonal gammopathy complicated by infection, and to analyze the correlation between the two.200 patients diagnosed with monoclonal gammopathy by MALDI-TOF MS were included, of which 100 had concurrent infections and 100 did not. An additional 100 healthy controls, matched for age and gender, were also enrolled.By comparing the composition of the gut microbiota and immune function markers (such as peripheral blood immune cell profiles and cytokine levels) between the patient groups and the control group, the study will evaluate the dysbiosis of the gut microbiota and abnormal immune status in patients with monoclonal gammopathy complicated by infection. The aim is to explore the correlation between the gut microbiome alterations and immune dysfunction, in order to provide a basis for further investigation of the underlying mechanisms.
