Vascular glycosaminoglycans (GAG) are essential components of the endothelium and vessel wall and have been shown to be involved in several biologic functions. Mesoglycan, a natural GAG preparation, is a polysaccharide complex rich in sulphur radicals with strong negative electric charge. It is extracted from porcine intestinal mucosa and is composed of heparan sulfate, dermatan sulfate, electrophoretically slow-moving heparin, and variable and minimal quantities of chondroitin sulfate. Data on antithrombotic and profibrinolytic activities of the drug show that mesoglycan, although not indicated in the treatment of acute arterial or venous thrombosis because of the low antithrombotic effect, may be useful in the management of vascular diseases, when combined with antithrombotics in the case of disease of cerebral vasculature, and with antithrombotics and vasodilator drugs in the case of chronic peripheral arterial disease. The protective effect of mesoglycan in patients with venous thrombosis and the absence of side effects, support the use of GAG in patients with chronic venous insufficiency and persistent venous ulcers, in association with compression therapy (zinc bandages, multiple layer bandages, etc.), elastic compression stockings, and local care, and in the prevention of recurrences in patients with previous DVT following the standard course of oral anticoagulation treatment.
血管糖胺聚糖(GAG)是内皮和血管壁的重要组成部分,已被证明参与多种生物学功能。中聚糖是一种天然的GAG制剂,是一种富含硫自由基且带有强负电荷的多糖复合物。它从猪肠黏膜中提取,由硫酸乙酰肝素、硫酸皮肤素、电泳迁移缓慢的肝素以及少量可变的硫酸软骨素组成。关于该药物抗血栓形成和促纤维蛋白溶解活性的数据表明,中聚糖虽然因其抗血栓作用低而未被用于治疗急性动脉或静脉血栓形成,但在血管疾病的管理中可能有用,在脑血管疾病时与抗血栓药物联合使用,在慢性外周动脉疾病时与抗血栓药物和血管扩张药物联合使用。中聚糖对静脉血栓形成患者的保护作用以及无副作用,支持在慢性静脉功能不全和持续性静脉溃疡患者中使用GAG,与压迫疗法(锌绷带、多层绷带等)、弹性压迫袜和局部护理联合使用,并在口服抗凝治疗标准疗程后预防既往深静脉血栓形成患者的复发。
