- Abstract
Objectives: Blood–brain barrier (BBB) disruption is a critical pathological process involved in neuromyelitis optica spectrum disorder (NMOSD). Here, we characterized the profile of five cell adhesion molecules in patients with NMOSD. Methods: We measured levels of cell adhesion molecules, including ICAM‐1, ICAM‐2, VCAM‐1, PECAM‐1, and NCAM‐1, in the serum of 28 patients with NMOSD, 24 patients with multiple sclerosis (MS), and 25 healthy controls (HCs). Results: ICAM‐2 levels (median: 394.8 ng/mL) were increased in patients with NMOSD compared with MS (267.1 ng/mL, P = 0.005) and HCs (257.4 ng/mL, P = 0.007), and VCAM‐1 and ICAM‐1 levels were higher in patients with NMOSD (641.9 ng/mL and 212.7 ng/mL, respectively) compared with HCs (465 ng/mL [P = 0.013] and 141.8 ng/mL [P = 0.002], respectively). However, serum PECAM‐1 levels were lower in patients with NMOSD (89.62 ng/mL) compared with MS (106.9 ng/mL, P = 0.015) and HCs (107.2 ng/mL, P = 0.007). Receiver operating characteristic curve analysis revealed that PECAM‐1 (area under the curve (AUC): 0.729) and ICAM‐2 (AUC: 0.747) had adequate abilities to distinguish NMOSD from MS, and VCAM‐1 (AUC: 0.719), PECAM‐1 (area under the curve: 0.743), ICAM‐1 (AUC: 0.778), and ICAM‐2 (AUC: 0.749) exhibited potential to differentiate NMOSD and HCs. Serum levels of PECAM‐1 also demonstrated a negative correlation with Kurtzke Expanded Disability Status Scale scores in patients with NMOSD. Interpretation: Our results reveal possible BBB breakdown signals specifically observed in NMOSD and highlight the potential role of cell adhesion molecules as biomarkers of this disease.
