| pubmed-article:20378011 | pubmed:abstractText | Rheumatoid arthritis (RA) is associated with an excess cardiovascular morbidity and mortality, related to systemic inflammation with endothelial dysfunction (ED) and impaired flow-mediated vasodilation (FMD). We assessed the FMD response to anti-TNF-alpha treatments in 28 RA patients, aged 49.8+/-15.3 years: an unpaired FMD was found in 66.7 percent of our cases and was restored after 6 weeks of anti-TNF-á treatment (13.5+/-5.3 percent vs 4.6+/-4.1 percent, p less than 0.05). Twenty-five percent of the infliximab patients demonstrated a long term response, compared with 60 percent of etanercept and 100 percent of adalimumab patients, after 2 years (p less than 0.01). Infections (3 cases), myocardial ischemia (1 case) or loss of response (4 cases) were associated with a worsened FMD, restored by shifting to adalimumab. The present study confirms that ED is an RA systemic disease marker, responsive to anti-TNF-alpha treatment and sensitive to clinical events or to a loss of response, underlying the biological coherence between synovial and endothelial inflammation. | lld:pubmed |
