OBJECTIVES: A body of evidence suggests the pivotal role of endothelial cells in the pathophysiology of systemic sclerosis. E-selectin is an adhesion molecule specifically expressed by activated endothelial cells. In previous studies we noticed that E-selectin was frequently expressed in the salivary gland tissue of patients with systemic sclerosis. Moreover, E-selectin expression was detectable very early in the course of the disease. To better define the role of E-selectin in the pathogenesis of systemic sclerosis, we conducted a study aimed at determining whether E-selectin expression was correlated to clinical and biological features in patients with systemic sclerosis.
METHODS: Thirty-one patients presenting with systemic sclerosis were included in the study. The following parameters were systematically assessed: duration and cutaneous extent of the disease, presence of secondary Sjögren's syndrome, antinuclear antibodies, and pulmonary and esophagus involvement. E-selectin expression was assessed by immunocytochemistry on minor labial salivary glands.
RESULTS: E-selectin expression was detected in 21 out of 31 patients (67%). The disease duration was significantly shorter in patients with E-selectin expression (mean 9.1 +/- 8.5 years versus 4.2 +/- 3.3 years, P < 0.05). No significant difference was found for other features.
CONCLUSIONS: This study shows that endothelial E-selectin expression is mainly detectable early in the course of systemic sclerosis, when active and non-cicatrical sclerosis may be evidenced. No correlation was found between E-selectin expression and immunological disorders (antinuclear antibodies, secondary Sjögren's syndrome).
