In order to investigate whether soluble intercellular adhesion molecule- 1
(sICAM-1) and soluble interleukin-2 receptors (sIL-2R) were present in
scleroderma skin, and to compare their levels to concentrations measured in
plasma and clinical parameters, we examined suction blister fluid and
plasma from 13 patients with systemic sclerosis and 11 healthy volunteers.
Suction blisters and biopsies were from the transition zone between normal
skin and scleroderma, and uninvolved abdominal skin. The levels of sICAM-1
and sIL-2R were significantly increased in both plasma and suction blister
fluid from systemic sclerosis patients compared with healthy volunteers.
ICAM-1 was localized to vessels and perivascular mononuclear infiltrates by
immunohistochemical methods. IL-2R was expressed by CD3-positive cells. The
elevated levels of sICAM-1 and sIL-2R in suction blister fluid point
towards activation of endothelial cells and T cells in both the transition
zone and uninvolved skin of systemic sclerosis patients.
