title: Circulating E-selectin and tumor necrosis factor-alpha in extraarticular involvement and joint disease activity in rheumatoid arthritis.
abstract: In this cross-sectional study, we assessed the relationship between circulating TNF-alpha and E-selectin (sE-selectin) with extraarticular involvement and severity of joint disease in RA. We compared 56 patients who had RA and extraarticular involvement (ExRA) with a group of 84 patients with only articular involvement (non-ExRA). ExRA had higher circulating TNF-alpha than non-ExRA (32 +/- 9 vs. 28 +/- 6 pg/mL, P = 0.002). sE-selectin levels did not differ between both groups. sE-selectin correlated with tender joint count (rho = 0.19, P = 0.03), morning stiffness (rho = 0.19, P = 0.03), severity of pain (rho = 0.21, P = 0.02), disease activity (assessed by the patient) (rho = 0.21, P = 0.02), HAQ-DI (rho = 0.29, P = 0.004), and rheumatoid factor titers (rho = 0.31, P = <0.001). Circulating TNF-alpha had no correlation with sE-selectin or disease activity. We concluded that sE-selectin correlated with severity of joint disease, further follow-up studies should evaluate if sE-selectin is useful as prognosis marker for progression of articular damage.
