Background: Rheumatoid arthritis (RA) is a chronic disease of unknown etiology, manifested primarily by inflammation of the peripheral joints. The pathogenic mechanisms responsible for the onset and maintenance of the joint inflammation in RA still make it object of investigations. We will discuss some of the aspects of the involvement of magnesium (Mg) in the pathologic processes of RA. Objectives: To estimate the blood levels of Mg in a group of

Abstract Background: During the last decade, anticyclic citrullinated peptides (anti-CCP) have been proposed as an important tool for early arthritis diagnosis. Objectives: To determine the diagnostic value, specificity and sensitivity of anti-CCP3 as a new test for RA, the prevalence of anti-CCP3 IgG in early rheumatoid arthritis patients (
