Rheumatoid arthritis is a chronic inflammatory systemic disease. It has a worldwide distribution and can affect all age group. The peak incidence is between fourth and sixth decade. It is more prevalent in women, and it’s prevalence in the general population in North America is between 0.2-1.5%. The etiology of RA is unknown, although clusters of the disease in families and high concordance in mono-zydotic twins support genetic predisposition. The prevalence of fatty liver disease in patients with rheumatoid arthritis is currently unknown. We wish to study the link between the two conditions by performing a son graphic imaging of the liver in a cohort of RA patients. If indeed a high prevalence of NAFLD will be found in the RA patients, further support will be landed for the link between inflammation and fatty liver disease. These findings may also have implications regarding the management and follow up of RA patients.
