Gelsolin levels are decreased in ankylosing spondylitis patients undergoing anti-TNF-alpha therapy

To determine whether circulating gelsolin (GSN) levels in patients with ankylosing spondylitis (AS) undergoing TNF-α antagonist-infliximab-therapy are altered compared with controls and to establish whether disease activity, systemic inflammation and metabolic syndrome are potential determinants of...

description To determine whether circulating gelsolin (GSN) levels in patients with ankylosing spondylitis (AS) undergoing TNF-α antagonist-infliximab-therapy are altered compared with controls and to establish whether disease activity, systemic inflammation and metabolic syndrome are potential determinants of circulating GSN levels in these patients. We assessed GSN serum concentrations in a series of 30 non-diabetic AS patients without cardiovascular (CV) disease undergoing TNF-α antagonist-infliximab therapy and 48 matched controls. GSN levels were measured immediately before and after an infliximab infusion. Correlations of GSN serum levels with disease activity, systemic inflammation and metabolic syndrome were assessed. Potential changes in GSN concentration following an infusion of anti-TNF-α monoclonal antibody-infliximab were also analysed. Although at the time of the study AS patients undergoing anti-TNF-α therapy had adequate control of the disease (mean BASDAI 2.94), they showed lower GSN serum levels than healthy controls (mean±SD: 38660.42±23624.6 ng/ml versus 68975.43±31246.79 ng/ml; p

No association was found between GSN concentration and adipokines or biomarkers of endothelial cell activation. However, correlation between basal GSN levels and insulin resistance was observed.
