About this study

Official title: The Effect of Alpha-tocopherol in Hemolysis and Oxidative Stress Marker on the Red Cell

The accumulation of unpaired α-globin chains in β-thalassemia major patients may clinically create ineffective erythropoiesis, hemolysis, and chronic anemia. Multiple blood transfusions and iron overload cause cellular oxidative damage. However, α-tocopherol, an antioxidant, has been known as a potent scavenger of lipid radicals in the red cell membrane of β-thalassemia major patient. By this randomized controlled trial, the investigators would like to evaluate the effects of α-tocopherol in hemolysis and oxidative stress on the red cell membrane of β-thalassemia major.

Read the detailed description

Background: The accumulation of unpaired α-globin chains in β-thalassemia major patients may clinically create ineffective erythropoiesis, hemolysis, and chronic anemia. Multiple blood transfusions and iron overload cause cellular oxidative damage. However, α-tocopherol, an antioxidant, has been known as a potent scavenger of lipid radicals in the red cell membrane of β-thalassemia major patients.

Purpose: To evaluate the effects of α-tocopherol in hemolysis and oxidative stress on the red cell membrane of β-thalassemia major.

Methods: In this randomized controlled trial, the investigators allocated subjects in the placebo and α-tocopherol groups. Doses of α-tocopherol were based on the recommendation of Institute of Medicine: 4-8 years old 200 mg/day; 9-13 years old 400 mg/day; 14-18 years old 600 mg/day. Hemolysis, oxidative stress, and antioxidant variables were evaluated before and after 4 weeks of consuming either α-tocopherol or placebo, performed prior to blood transfusions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The effects of α-tocopherol in hemolysis marker on the red cell membrane of β-thalassemia major

    The plasma haptoglobin and hemolysis as hemolysis marker on alpha-tocopherol treatment were assessed by ELISA using Haptoglobin and Hemopexin kit for human

    Measured: 4 weeks

Secondary outcomes (2)
  1. The effects of α-tocopherol in oxidative stress marker on the red cell membrane of β-thalassemia major

    The malondialdehyde plasma level as oxidative stress marker on alpha-tocopherol treatment was assessed by Spectrophotometry using TBARS method.

    Measured: 4 weeks

  2. The effects of α-tocopherol in endogenous antioxidant on the red cell membrane of β-thalassemia major

    The Glutathione as endogenous antioxidant marker on alpha-tocopherol treatment was assessed by ELISA method by using GT40 for Glutathione kit

    Measured: 4 weeks

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The effects of α-tocopherol in hemolysis marker on the red cell membrane of β-thalassemia major (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03948737, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
