Detection of Dysbiosis and Increased Intestinal Permeability in Brazilian Patients with Relapsing-Remitting Multiple Sclerosis.

Dysbiosis, associated with barrier disruption and altered gut-brain communications, has been associated with multiple sclerosis (MS). In this study, we evaluated the gut microbiota in relapsing-remitting patients (RRMS) receiving disease-modifying therapies (DMTs) and correlated these data with diet, cytokines levels, and zonulin concentrations. Stool samples were used for 16S sequencing and real-time PCR.

Detection of Increased Relative Expression Units of and , and Decreased in Stool Samples from Brazilian Rheumatoid Arthritis Patients: A Pilot Study.

Interactions between gut microbes and disease modifying antirheumatic drugs (DMARDs) have been proposed. The aim of the present study was to evaluate the presence of some specific bacteria in stool samples from Brazilian RA patients receiving DMARDs and correlate these data with diet, clinical parameters, and cytokines. Stool samples were used for gut bacteria evalutation by qPCR.
