Intercellular Adhesion Molecule-1 (ICAM-1) is a cytokine-inducible adhesion molecule expressed on cells of multiple lineages at sites of inflammation. Recently a truncated form of ICAM-1 has been discovered to be circulating in serum. This study reports on circulating serum (cICAM-1) levels in 132 uveitis patients (HLA-B 27 pos. acute anterior uveitis (AAU); HLA-B27 neg. anterior uveitis (AU); intermediate uveitis (IU); heterochromic cyclitis Fuchs (HCF); sarcoidosis; Toxoplasmosis). Measurement of circulating ICAM-1 serum levels was performed using a monoclonal antibody based ELISA, with healthy blood donors serving as the control group. Applying multiple variance analysis and the Student Newmann-Keuls test we found a statistically significant elevation of serum cICAM-1 level in the HLA-B 27 neg. AU group (n:31), in the IU group (n:25) and in patients with sarcoidosis (n:18). Serum levels of HLA-B27 pos. AAU patients, patients with HCF and patients suffering from ocular toxoplasmosis did not differ significantly from levels of the control group.

Adhesion molecules play a critical role in leukocyte emigration to a site of inflammation. In order to assess the potential therapeutic benefit of blocking adhesion molecule function in anterior uveitis, the efficacy of antibodies to specific adhesion molecules was tested in 3 separate rabbit models of anterior uveitis. Antibodies to two different leukocyte molecules, CD11a and CD18, and antibodies to the endothelial ligand for CD11a/CD18, ICAM-1 (intercellular adhesion molecule-1, CD54), were studied in inflammation after intravitreally injected interleukin-1, intravitreally injected endotoxin, or an ocular reversed passive Arthus reaction. The CD18 antibody (2 mg/kg intravenously) reduced the cellular infiltrate with each of these 3 models. The antibody to CD11a was equally effective but was tested only in the IL-1-induced model. The antibody to ICAM-1 reduced the cellular infiltrate associated with this model, but the results did not reach statistical significance. None of the antibodies was able to reduce the associated increase in vascular permeability as measured by protein in the aqueous humor. The antibody to CD18 failed to reduce the inflammation if it was administered 24 hours after the intravitreally injected endotoxin. These observations demonstrate that leukocyte migration into the anterior segment of the eye is dependent on the CD11a/CD18 complex.
