Overview

Randomized trial examines iron overload and biomarkers in patients with non-transfusion-dependent thalassaemias, highlighting risk factors for increased iron absorption.

Key Points

  • This research aims to explore iron metabolism and its biomarkers in patients with non-transfusion-dependent thalassaemias (NTDT).
  • Examined 166 NTDT patients including β thalassaemia intermedia, Hb E/β thalassaemia, and Hb H syndromes.
  • Measured liver iron concentration, serum ferritin, transferrin saturation, and non-transferrin-bound iron (NTBI).
  • Analyzed correlations between biomarkers based on transfusion history and splenectomy status.
  • Elevated NTBI, TfSat, NRBCs, and SF were found in splenectomised patients compared to non-splenectomised patients.
  • Increased NTBI and risk of extra-hepatic iron distribution were linked to prior blood transfusions and TfSat >70%.
  • Plasma hepcidin levels remained similar across subgroups but decreased with more than 20 prior transfusions.
