Gut Microbes Associated with Presence of Rheumatoid Arthritis

 

New-onset rheumatoid arthritis (NORA) has been found to correlate with presence of Provotella copri microbes in the gut of untreated patients. The presence of P. copri was associated with lower levels of beneficial microbes such as Bacteroides. P. copri levels in patients with established RA were the same as those in healthy individuals, leading researchers to believe that the microbe requires an inflammatory environment to survive since patients already undergoing treatment with anti-inflammatory medications would not have this type of gut environment.
