Partially conflicting evidence about endothelial markers and their relationships with clinical complications after BMT has been reported in the literature. Since almost all studies were carried out in adults, we evaluated some recent available markers of endothelial cell function in pediatric patients undergoing stem cell transplantation (SCT) for acute leukemia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Procedure<\/jats:title><jats:p>We studied the variation in circulating serum endothelial\u2010selectin (ES), leukocyte\u2010selectin (LS), thrombomodulin (TM), von Willebrand factor (vWF), nitrate\u2009+\u2009nitrite (NO<jats:sub>2<\/jats:sub><jats:sup>\u2212<\/jats:sup>\/NO<jats:sub>3<\/jats:sub><jats:sup>\u2212<\/jats:sup>), endothelin\u20101 (EN), and tissue factor (TF) in 21 pediatric patients undergoing SCT for acute leukemia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>ES and LS significantly lowered following SCT and returned to pre\u2010SCT levels 4 weeks after the procedure.

Also, TM and vWF increased, although such changes did not reach statistical significance. EN and TF did not appreciably change. A strong correlation was observed between white blood cell (WBC) count and both ES and LS, as well as between such selectins. TM significantly correlated with both selectins and NO<jats:sub>2<\/jats:sub><jats:sup>\u2212<\/jats:sup>\/NO<jats:sub>3<\/jats:sub><jats:sup>\u2212<\/jats:sup>. The pre\u2010conditioning levels of TM and vWF in patients undergoing major complications, considered altogether, were significantly lower and higher, respectively, than in uncomplicated patients.

Both selectins were significantly higher in allo\u2010 than in auto\u2010transplanted patients 4 weeks after SCT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our data support the hypothesis of severe endothelial damage after conditioning and SCT, particularly allogeneic. However, the increase in TM, which has strong anticoagulant properties, and metabolites of NO, involved also in protective actions, may reflect regeneration of the anti\u2010thrombotic endothelial function. This could take place after transitory functional impairment, rather than pure endothelial damage.
