Transition from intravenous (IV) epoprostenol to IV treprostinil in patients with pulmonary hypertension (PH) has traditionally been performed by gradually decreasing the epoprostenol dose while increasing the treprostinil dose. Preliminary data suggest that this transition can be performed more rapidly without the need for epoprostenol weaning. We conducted a single center, prospective clinical trial to assess the safety, efficacy, and treatment satisfaction of rapidly switching from epoprostenol to IV treprostinil.
This study included patients with PH who had rapidly transitioned from epoprostenol to IV treprostinil. Data collected included clinical status, adverse events, PH symptoms, and previously validated measures of quality of life and treatment satisfaction.
Ten patients were enrolled in this study. Exercise capacity measured by mean 6-min walk distance was maintained from baseline throughout follow-up. Severity of disease as assessed by WHO functional class was maintained or improved for the majority of patients. Adverse events were minimal during the transition, and all patients remained on IV treprostinil throughout the follow-up period. A favorable impact on quality of life and treatment satisfaction measures was observed by eight weeks following the transition from epoprostenol to IV treprostinil. Specifically, time spent on drug preparation activities decreased by 39.5% with treprostinil compared to epoprostenol.
Rapidly switching from epoprostenol to IV treprostinil can be achieved without safety concerns, with minimal patient monitoring and without the need for extended hospitalization, while favorably impacting on patients' quality of life.
肺动脉高压(PH)患者从静脉内(IV)依前列醇转换为 IV 曲前列尼尔时,传统上是通过逐渐减少依前列醇剂量同时增加曲前列尼尔剂量来完成。初步数据表明,无需进行依前列醇减药即可更快地进行这种转换。我们进行了一项单中心前瞻性临床试验,以评估从依前列醇快速转换为 IV 曲前列尼尔的安全性、疗效和治疗满意度。
这项研究纳入了从依前列醇快速转换为 IV 曲前列尼尔的 PH 患者。收集的数据包括临床状况、不良事件、PH 症状以及先前验证过的生活质量和治疗满意度衡量指标。
这项研究纳入了 10 名患者。通过平均 6 分钟步行距离测量的运动能力在整个随访期间保持基线水平。大多数患者的疾病严重程度(通过世界卫生组织功能分级评估)保持或改善。在转换过程中不良事件很少,所有患者在整个随访期间都继续接受 IV 曲前列尼尔治疗。从依前列醇转换为 IV 曲前列尼尔后 8 周观察到对生活质量和治疗满意度衡量指标的有利影响。具体而言,与依前列醇相比,使用曲前列尼尔时用于药物准备活动的时间减少了 39.5%。
从依前列醇快速转换为 IV 曲前列尼尔不会产生安全问题,患者监测最少,无需延长住院时间,同时对患者的生活质量产生有利影响。
