title: [Evaluation of arteriolar reactivity and blood coagulation parameters during picotamide treatment].
abstract: Thirty-two patients, nineteen males and thirteen females, mean age 59.4 +/- 11.9 years, 18 with peripheral arteriopathy Fontaine stage II and 14 with cerebral vasculopathy were submitted to treatment with picotamide, 900 mg/die. In basal conditions and after 30 and 60 days of treatment, we evaluated some blood clotting parameters concerning both platelets (circulating platelet aggregates, beta-thromboglobulin, TxB2, 6-keto-pgF1 alpha) and plasma (fibrinogen, plasminogen, ATIII, Factor VIII-C and VIII Ag, prothrombin time, activated thromboplastin time) and some instrumental parameters such as walking distance and Doppler with a post-ischaemic hyperaemia test in patients with peripheral arteriopathy and Doppler of epiaortic vessels with resistance and pressure-perfusion index evaluation in patients with cerebral vasculopathy. Treatment with picotamide significantly reduced circulating platelet aggregates, beta-TG and TxB2 levels, without change of 6-keto-PGF-alpha values, with reduction of F VIII-C and slight increase of plasminogen and ATIII levels. In patients with peripheral arteriopathy after two months, a significant increase in distance and an improvement of arteriolar reactivity were observed, as shown by increase of the perfusion-index and by reduction of the post-ischaemic recovery time. These observations, together with the good tolerance of the drug, justify the use of picotamide in the treatment of patients with atherosclerotic vasculopathy at different localizations.
