BACKGROUND: To evaluate if conjunctival epithelial cells' expression of HLA-DR and ICAM-1 could be helpful as early topical markers of inflammation in Graves' orbitopathy (GO).
METHODS: The ocular examination evaluated a clinical activity score (CAS) by assessment of clinical features, (e.g., eyelid or conjunctival inflammation, lid width, lid closure, proptosis, ocular motility). Conjunctival epithelial cell specimens for flow-cytometric evaluations of ICAM-I and HLADR expression were collected by impression cytology from ten eyes with active GO (CAS ≥ 4 and duration ≤ 12 months), from 15 eyes with Graves' disease (GD) without active GO (CAS 0-2) and from 15 normal specimens without any ocular disorders.
RESULTS: The percentage of HLA-DR + conjunctival epithelial cells was significantly elevated in patients with active GO comparing to GD without active GO and healthy controls, 10.7 % (8.5-17.7) and 7.78 % (3.92-10.1) (p < 0.05) vs. control 4.89 % (3.5-5.5) (p < 0.005), respectively. The expression of ICAM - 1+ conjunctival epithelial cells was greater only in patients with GO vs. controls, 5.5 % (4.8-7.03) and 1.46 % (0.69-2.51) (p < 0.005), respectively.
CONCLUSION: The percentage of HLA-DR⁺ and ICAM-1⁺ conjunctival epithelial cells in patients with the active GO may serve as a topical inflammation marker in Graves' orbitopathy.
