Detection of circulating adhesion molecules in erythrodermic skin disease.
BACKGROUND
Diagnosis of the underlying dermatosis in erythroderma is often difficult. The cause of increased mortality in erythroderma, particularly in relation to infection, is incompletely understood.


OBJECTIVE
We investigated the potential diagnostic use of circulating intercellular adhesion molecule-1 (cICAM-1), vascular cell adhesion molecule-1 (cVCAM-1), and E-selectin (cE-selectin) levels in erythroderma.


METHODS
cICAM-1, cVCAM-1, and cE-selectin were measured by enzyme-linked immunosorbent assay in 14 patients with erythroderma of known cause and in 17 control subjects. Levels were correlated with other markers of the inflammatory response.


RESULTS
In erythroderma median cICAM-1, cVCAM-1, and cE-selectin levels were significantly elevated, but no difference was found between values in patients with eczema and values in those with psoriasis. Circulating adhesion molecule levels did not correlate with erythrocyte sedimentation rate or total white blood cell count.


CONCLUSIONS
cICAM-1, cVCAM-1, and cE-selectin were detectable in patients with erythroderma but were not differential diagnostic use in this study. Because in vitro these molecules may interfere with normal cell adhesion mechanisms, we speculate that they may contribute to the immunosuppressive state in these patients.
