Официальное название

Effect of Oral sucRosomIal Iron on exerciSE Capacity and Quality of Life in Patients With Heart Failure: a Randomized, Placebo-controlled Trial (RISE-HF)

Обзор

The goal of this study is to investigate the effect of oral sucrosomial iron on exercise capacity and quality of life in patients with heart failure (HF) and iron deficiency (ID). The main question the study aims to answer is whether oral sucrosomial iron improved exercise capacity, assessed by six-minute walk test, and quality of life, assessed by Kansas City Cardiomyopathy Questionnaire, compared with placebo. One group of participants will receive treatment with oral sucrosomial iron and the other group will receive treatment with placebo.

Подробное описание

Based on clinical trials, treatment with intravenous iron improves symptoms, exercise capacity, and may reduce HF hospitalizations in patients with HF and ID. On the contrary, treatment of ID with oral iron has no effect on exercise capacity. High hepcidin levels prevent oral intestinal absorption and blunt the response to oral iron administration. Sucrosomial iron (SI) consists of a nucleus of ferric pyrophosphate with an envelope of sucrose ester of fatty acids, which promotes intestinal absorption through paracellular and lymphatic routes, independent of hepcidin. In contrast with intravenous iron infusion, administration of oral iron may not promote oxidative stress, since the intestinal iron absorption prevent the formation of labile, non-transferrin bound, plasma iron.

The study will investigate the effect of oral SI supplementation on exercise capacity, assessed by six-minute walk test, and quality of life, assessed by Kansas City Cardiomyopathy Questionnaire, compared with placebo in patients with HF, a left ventricular ejection fraction (LVEF) \<50%. Iron deficiency was defined as transferrin saturation (TSAT) \<20%.

Вмешательства

• Пищевая добавка Sucrosomial iron
  Sucrosomial iron with the addition at a fixed dose of vitamin C to promote iron absorption (SiderAL® Forte) will be administered orally once a day for 24 weeks. The dose regimen for all participants will be calculated according to the haemoglobin (Hb) levels at baseline evaluation and to patient's body weight as follows: Hb 14-16 g/dL: 1 tablet once a day, corresponding to 30 mg/daily, for 24 weeks; Hb 10-13.9 g/dL: 2 tablets once a day, corresponding to 60 mg/daily, for 24 weeks
• Другое Placebo
  Placebo pills will be identical in shape, form and color of SI tablets; they will contain the same components of SiderAL Forte® except for sucrosomial iron and vitamin C. Placebo will be administered orally once a day for 3 months according to the same dose scheme in the intervention arm.
