An experimental clinical trial was carried out using heparan sulphate in order to assess its antithrombophilic, profibrinolytic and possibly hemorheological characteristics. Twenty patients with stage 2 obliterating arteriopathy of the lower limbs were enrolled in the study. Patients were fully informed regarding the experimental protocol: a controlled, crossover and double-blind study. The population sample included 20 subjects, male and female, mean age 60.9 years who received heparan sulphate at a dose of 200 mg/die (one 100 mg tablet twice a day): treatment continued for 120 days (60 days of treatment with heparan sulphate and 60 days with placebo). The results obtained were in favour of medical therapy which was significantly more effective than placebo in relation to a number of parameters: compared to basal values, walking parameters were improved, recovery times were more rapid and gait was longer. Significant changes in hemocoagulative and hemorheological parameters were also observed (euglobulin lysis time, fibrin degradation products, erythrocytic filtration, hematic viscosity) and their positive trend may account for peripheral hematic perfusion, as shown by photoplethysmographic tests, velocimetric tests and the modification of the Windsor index. Therapeutic efficacy and the good tolerance (one case of gastralgia, two of pyrosis) as well as broad safety margins offered by the drug justify the use of heparan sulphate in all clinical conditions characterized by thrombophilia and local ischemia, above all those which require long-term treatment.

The antianginal efficacy of metoprolol OROS has been investigated in comparison with that of atenolol in a multicenter double-blind cross-over trial carried out in patients with stable effort angina. OROS (ORally OSmotic) is a new semi-permeable delivery system with very slow osmotic release of the active drug, which is maintained at virtually constant plasma levels throughout the 24 hours. At the end of a 2-week run-in period, 53 patients with chronic coronary artery disease and documented ischemia during bicycleergometric exercise test were given, on double-blind condition, metoprolol OROS 21/285 and atenolol 100 mg in random order for 4 weeks each. On the last day of each cross-over period, patients underwent a bicycleergometric exercise test 24 hours after the last drug intake. The mean number of anginal attacks (2.54 during the 2-week run-in period) decreased under both metoprolol OROS (1.29 and 1.13 after 2 and 4 weeks of treatment, respectively) and atenolol (1.29 and 0.73 after 2 and 4 weeks of treatment, respectively), with no difference between the two beta-blockers. The same behaviour was observed as regards the nitroglycerin tablets consumption. The exercise test variables (i.e. duration of exercise, maximum workload and peak exercise values of systolic and diastolic blood pressure, heart rate and ST-segment depression) did not differ between the two treatments and did not show a time-effect. The percentage of patients reporting adverse effects was low with both treatments. Two patients were withdrawn from the study during atenolol (gastralgia and heartburn, respectively), and one during metoprolol OROS (gastralgia).(ABSTRACT TRUNCATED AT 250 WORDS)

Bowel atherosclerotic ischemia is one of the type of clinical presentation of this general inflammatory arterial disease. In this article was depicted a case of 58-year-old female with clinical presentation of chronic bowel ischemia, e.g., chronic stomach pain, defecation disturbance and cachexia. Diagnostic process, difficulties during diagnostic and therapy were presented. The patient was referred to the surgery The diagnostic process and surgical treatment performed in our hospital were compared with actual recommendations of specialists and standards.
