Brief Summary

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.
