Interaction of endothelial cells and neutrophilsin vitro: kinetics of thrombomodulin, intercellular adhesion molecule-1 (ICAM-1), E-selectin, and vascular cell adhesion molecule-1 (VCAM-1): implications for the relevance as serological disease activity markers in vasculitides
SUMMARYRecently markers of endothelial cell activation or injury gained increasing interest as serological parameters of disease activation in vasculitides. Among these, soluble serum thrombomodulin, ICAM-1, VCAM-1 and E-selectin are of particular interest. However, only thrombomodulin showed the expected close correlation. The objective of this study was to investigate in vitro the kinetics of these endothelial cell receptors after interaction of unstimulated or cytokine-activated polymorphonuclear neutrophils (PMN) and endothelial cells in order to find evidence explaining these different clinical findings. Over the time period of up to 48 h of incubation the kinetics of thrombomodulin, I…
Serum thrombomodulin—a reliable marker of disease activity in systemic lupus erythematosus (SLE): advantage over established serological parameters to indicate disease activity
SUMMARYTo date no specific serological parameter is available to assess disease activity in SLE. Soluble serum thrombomodulin is a new marker of endothelial cell injury and vasculitis. The objective of this study was to compare in vivo soluble thrombomodulin as marker of disease activity in SLE with established and recent serological parameters. One hundred and twenty-four sera of 30 patients with proven SLE with different disease activities were tested for serum levels of thrombomodulin, intercellular adhesion molecule-1 (ICAM-1), E-selectin, vascular cell adhesion molecule-1 (VCAM-1), IL-2R, IL-6, IL-10, dsDNA by ELISA and dsDNA additionally by radioimmunoassay (RIA). C-reactive protein (…
Comparison of a 48-Hour Infusion of 5-Fluorouracil without Folinic Acid with 24-Hour Folinic Acid/5-Fluorouracil in Patients with Metastatic Colorectal Cancer Refractory to Bolus Folinic Acid/5-Fluorouracil
<i>Background:</i> Out of various high-dose 5-fluorouracil (5-FU) regimens given with or without folinic acid (FA), the optimal 5-FU schedule has still to be defined as treatment for metastatic colorectal cancer (CRC). Consequently, we compared toxicity, response and survival following two FA/5-FU regimens in 55 CRC patients refractory to bolus FA/5-FU. <i>Methods:</i> Twenty-eight patients (group A) received 5-FU (60 mg/kg body weight) for 48 h, and 27 (group B) received 2-hour infusions of FA (500 mg/m<sup>2</sup>) and 24-hour infusions of 5-FU (2,600 mg/m<sup>2</sup>) until disease progression. <i>Results:</i> Both groups were a…
