Circulating levels of soluble E-selectin, ICAM-1 and VCAM-1 in bullous pemphigoid during low-dose methotrexate therapy. A prospective study.
Soluble iso-forms of cellular adhesion molecules (sCAMs) have been described and reported to be elevated in various inflammatory diseases. Elevated levels of sE-selectin have recently been detected and found to correlate with the number of blisters in bullous pemphigoid (BP) during oral corticosteroid therapy. In this prospective study we analysed levels of sCAMs in 10 elderly BP patients during low-dose oral pulse methotrexate monotherapy. We used standardised ELISA kits for soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1) and sE-selectin on 65 sera from 10 patients and 19 controls. Results were correlated with clinical parameters. Before therapy, we found significant elevation of sE-selectin (P=0.004) and sVCAM-1 (P=0.002) but not of sICAM-1. sE-selectin levels decreased during the efficient therapy and correlated with the number of blisters. Our results further support the proposition that sE-selectin might be a future clinical and predictive tool; but whether the elevation of sVCAM-1 also might reflect the disease activity in BP needs more investigation. The findings also indicate that BP might be more a cellularly mediated disease where interactions of different adhesion molecules play a crucial role.
