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.
