Reversible Cardiac Hypertrophy in Pulmonary Arterial Hypertension Treated With High-Dose Epoprostenol.

ABSTRACT: Although current guidelines recommend the use of prostanoid infusion that includes epoprostenol for high-risk pulmonary arterial hypertension patients, epoprostenol has many adverse effects. We report a case of a heritable pulmonary arterial hypertension patient who had transient biventricular hypertrophy during high-dose administration of epoprostenol. In this case, biventricular hypertrophy with worsening of dyspnea was observed during the uptitration of epoprostenol. Inflammatory diseases and endocrine disorders were ruled out as causes of the ventricular hypertrophy. After epoprostenol was changed to intravenous treprostinil, the biventricular hypertrophy normalized, in connection with dyspnea improvement. The use of high-dose epoprostenol may contribute to cardiac hypertrophy.

Project description:IntroductionPulmonary arterial hypertension (PAH) is associated with poor prognosis despite significant recent advances in its treatment. An intravenous formulation of epoprostenol sodium containing glycine and mannitol (epoprostenol GM; GlaxoSmithKline, London, UK) is widely used to treat PAH. A new formulation of epoprostenol sodium containing arginine and sucrose excipients (epoprostenol AS; Actelion Pharmaceuticals Japan Ltd., Tokyo, Japan) shows better stability at room temperature after preparing diluted solutions. The primary objective of this study was to evaluate the safety and tolerability of switching from epoprostenol GM to epoprostenol AS in Japanese patients with PAH. The authors also evaluated the efficacy and treatment satisfaction after switching formulations.MethodsThis was a two-site, open-label, single-arm, Phase 3b study. Eight adult Japanese PAH patients (seven females) treated with a stable dose of epoprostenol GM for ≥30 days were switched to epoprostenol AS and followed for 12 weeks. Outcomes included safety, changes from baseline to 12 weeks in pulmonary hemodynamic factors (pulmonary vascular resistance, mean pulmonary arterial pressure, and cardiac output), and treatment satisfaction, assessed using the Treatment Satisfaction Questionnaire for Medication (TSQM-9).ResultsThe mean (range) age and time since diagnosis of PAH were 48 (25-69) years and 6.2 (0.6-13.9) years, respectively. There were no unexpected safety or tolerability concerns after switching formulations. The epoprostenol dose was maintained after switching formulations. There were no significant changes in pulmonary hemodynamic factors from baseline to week 12. Regarding treatment satisfaction, there was a significant improvement in convenience, which is demonstrated in the score of the domain increased from 51.40 ± 10.19 at baseline to 58.33 ± 12.96 at week 12 (P < 0.05).ConclusionsSwitching from epoprostenol GM to the same dose of epoprostenol AS was well tolerated over 12 weeks of treatment, and pulmonary hemodynamics were maintained. Switching to epoprostenol AS was also associated with improvements in treatment satisfaction (convenience). Clinical Trials: JapicCTI-122017.
