Therapeutic plasma exchange (TPE) or plasmapheresis has been used in various life-threatening diseases as a primary treatment or in combination with other therapies. It was first successfully employed in the 1960s for diseases like Waldenström's disease and myeloma. Since then, TPE techniques using apheresis membranes have been introduced. Apheresis therapies separate plasma components from blood using membrane screening or centrifugation methods. TPE aims to remove substances involved in the pathophysiology of diseases. It selectively removes high-molecular-weight molecules, substances with prolonged half-life, and those associated with disease pathogenesis. TPE can be performed using membranes or centrifugation, with replacement of extracted plasma volume using albumin or fresh frozen plasma. TPE requires specific competencies in nephrology and can be prescribed and monitored by nephrologists and performed by dialysis nursing staff. TPE can be combined with adsorption-based therapies to enhance its effect, and this approach is called plasma filtration adsorption. Another variation is double plasma filtration, which selectively removes substances based on molecular size. TPE can also be combined with lipoprotein removal strategies for managing familial hypercholesterolemia. TPE is an affordable extracorporeal therapy that benefits patients with life-threatening diseases. It requires collaboration between nephrologists and other specialists, and our results demonstrate successful TPE without anticoagulation in general hospitalization or outpatient settings.
治疗性血浆置换(TPE)或血浆分离术已被用于各种危及生命的疾病中,作为主要治疗方法或与其他疗法联合使用。它于 20 世纪 60 年代首次成功应用于瓦尔登斯特伦病和骨髓瘤等疾病。从那时起,使用血浆分离膜的 TPE 技术已经问世。血浆分离疗法使用膜筛选或离心方法将血浆成分与血液分离。TPE 的目的是去除疾病病理生理学中涉及的物质。它选择性地去除高分子量分子、半衰期长的物质以及与疾病发病机制相关的物质。TPE 可以使用膜或离心来进行,使用白蛋白或新鲜冷冻血浆替代提取的血浆体积。TPE 需要肾病学方面的特定专业知识,可由肾病学家进行处方和监测,并由透析护理人员进行操作。TPE 可以与基于吸附的疗法结合使用以增强其效果,这种方法称为血浆滤过吸附。另一种变化是双血浆滤过,它根据分子大小选择性地去除物质。TPE 还可以与脂蛋白去除策略结合使用,以治疗家族性高胆固醇血症。TPE 是一种负担得起的体外治疗方法,可使患有危及生命疾病的患者受益。它需要肾病学家和其他专家之间的协作,我们的结果表明,在一般住院或门诊环境中,无需抗凝即可成功进行 TPE。
