Abstract
Background: S100 plays an important role in diagnosis and prognosis of acute ischemic stroke. The objective was to investigate the effects of clinical heparins administrations on serum S100 concentrations in patients with cerebrovascular diseases.
Methods: Forty cases were enrolled in this study, including 10 patients with percutaneous carotid intervention receiving intravenous unfractionated heparin (UFH) at the beginning of stenting (group A1), 10 patients with carotid angiography receiving UFH-free therapy (group A2), 10 patients with cerebral infarction receiving subcutaneous low molecular weight heparin (LMWH) anticoagulation therapy (group B1) and 10 patients with cerebral infarction receiving LMWH-free therapy (group B2). S100 concentrations were analyzed before and after heparin administrations.
Results: A rapid increase of serum S100 (median, 1.74–fold, p<0.05) was observed in group A1 within 15 min of UFH administration. In group B1, S100 significantly increased (median, 1.44-fold, p<0.05) at 3 h after LMWH injection.
Conclusions: Both intravenous UFH and subcutaneous LMWH administration induced increases in serum S100 concentrations. It should be taken into account when using S100 as a biomarker of cerebrovascular diseases.
Keywords: heparin; heparin, low-molecular-weight; injections, intravenous; injections, subcutaneous; S100 protein
