Retrospective data reveals increased iron overload and mortality in transfusion-dependent patients, highlighting chelation challenges.

This study aimed to define the prevalence and severity of iron overload in transfusion-dependent Diamond-Blackfan anemia patients.
Collected retrospective data from 53 patients with Diamond-Blackfan anemia syndrome
Measured liver iron concentration and cardiac iron using MRI technologies
Analyzed data for associations between genotype and iron overload severity
Iron overload was present in 86% of patients, while cardiac iron overload occurred in 25%
Mortality linked to severe iron overload was highlighted as significant
Deferasirox was the primary chelation therapy used in 69.8% of patients

Yvonne Harrington (2025) studied this question.
