چکیده
OBJECTIVE To evaluate the degree of blood-brain barrier disruption in patients with neuromyelitis optica (NMO) and to clarify whether the levels of soluble intercellular adhesion molecule 1 (sICAM-1) and soluble vascular cell adhesion molecule 1 (sVCAM-1) in patients with NMO can be useful biomarkers for blood-brain barrier breakdown. DESIGN Descriptive historical cohort. SETTING Department of Neurology, Graduate School of Medicine, Chiba University. PATIENTS The levels of sICAM-1 and sVCAM-1 in 25 patients with NMO, 21 patients with multiple sclerosis, and 20 patients with other noninflammatory neurologic disorders in the serum and cerebrospinal fluid (CSF) were measured using a multiplexed fluorescent magnetic bead-based immunoassay. MAIN OUTCOME MEASURES Levels of the soluble adhesion molecules in serum and CSF and their associations with blood-brain barrier disruption. RESULTS The CSF levels of sICAM-1 and sVCAM-1 increased in patients with NMO compared with patients with multiple sclerosis and other noninflammatory neurologic disorders (P < .001), and serum levels of sICAM-1 increased in patients with NMO compared with healthy control individuals (P = .003). The CSF sICAM-1 levels from patients with NMO were correlated with the albumin quotient (P = .02) and the presence of lesions detected via gadolinium-enhanced magnetic resonance imaging. CONCLUSIONS Severe blood-brain barrier breakdown occurs in patients with NMO. Measuring adhesion molecules is useful to evaluate this barrier disruption.

Increased plasma levels of soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular cell molecule-1 (sVCAM-1) associated with disease severity in a primate model for severe human malaria: Plasmodium coatneyi-Infected Japanese macaques (Macaca fuscata).
In the present study, we investigated plasma levels of soluble intercellular adhesion molecule-1 (sICAM-1) and vascular cell adhesion molecule-1 (sVCAM-1) in seven Japanese macaques (Macaca fuscata) infected with Plasmodium coatneyi. Concentrations of sICAM-1 and sVCAM-1 were significantly elevated in the severe phase; the levels were maximally increased up to six times and three times those be...

BACKGROUND Elevated levels of soluble cellular adhesion molecules have been linked to the development of occlusive coronary events in otherwise healthy individuals. It is not certain, however, whether similar relationships exist for the development of early systemic atherosclerosis. METHODS AND RESULTS In a prospective, nested case-control study conducted among 14 916 middle-aged men, we eval...
متن کاملPerfusion with sickle erythrocytes up-regulates ICAM-1 and VCAM-1 gene expression in cultured human endothelial cells.
Sickle cell anemia is characterized by periodic vasoocclusive crises. Increased adhesion of sickle erythrocytes to vascular endothelium is a possible contributing factor to vasoocclusion. This study determined the effect of sickle erythrocyte perfusion at a venous shear stress level (1 dyne/cm(2)) on endothelial cell (EC) monolayers. Sickle erythrocytes up-regulated intercellular adhesion molec...

Background & Aims : Aging and the loss of endogenous estrogen production after menopause are accompanied by increases in blood pressure and endothelial dysfunction. Exercise training improves endothelial function in patients with hypertension. The aim of this study was to examine the effect of aerobic training on some markers of endothelial function in hypertensive postmenopausal women. M...
