Distal Airway Dysbiosis Present in Early RA

Image result for airway dysbiosis

Distal airway dysbiosis is present in untreated early rheumatoid arthritis (RA) and similar to that detected in sarcoidosis lung inflammation, according to a recent study. This community perturbation, which correlates with local and systemic autoimmune/inflammatory changes, may potentially drive ini...

Evidence of Gut Microbe Found in RA Patients

Subgroups of rheumatoid arthritis (RA) patients have differential IgG or IgA immune reactivity with Prevotella copri, an intestinal microbe, which appears to be specific for this disease, according to a recent study. These observations provide evidence that P. copri is immune-relevant in RA pathogen...

IgA ACPA and Plasmablasts Point to Microbiome in Pre-Clinical Rheumatoid

Serum antibodies precede the development of clinical rheumatoid arthritis (RAby) by many years, and yet we still have much to learn about this preclinical phase. Of particular interest has been the observation that IgA anti-CCP antibodies are commonly encountered in patients with RA raising question...

Gut Microbiome Shapes Risk and Response in Rheumatoid Arthritis

In Genome Medicine, Mayo Clinic researchers investigated a cohort of rheumatoid arthritis (RA) patients, their relatives and a healthy control group analyzing the gut microbiome vial16S ribosomal DNA analysis of fecal samples. They showed that RA had decreased gut microbial diversity which correlate...

Could Some Infections Protect Against Rheumatoid Arthritis?

Scientists have long suspected that certain bacterial infections may trigger RA.
Infections of the gastrointestinal and urogenital tracts appear to reduce RA risk, but prostate and respiratory infections do not.
