Summary
Diabetes mellitus in thalassaemia major patients is linked to iron overload and liver disease. Early detection and monitoring are crucial for managing complications in these high-risk individuals.
Area of Science:
- Endocrinology
- Hematology
- Metabolic Disorders
Background:
- Thalassaemia major patients are at increased risk for diabetes mellitus.
- Iron overload from frequent transfusions contributes to complications.
Purpose of the Study:
- To investigate the incidence and characteristics of diabetes mellitus in thalassaemia major patients.
- To identify risk factors and complications associated with diabetes in this population.
Main Methods:
- Retrospective analysis of 448 thalassaemia major patients across seven Italian centers.
- Evaluation of clinical presentation, diagnosis age, transfusion history, iron chelation therapy, liver function, and C-peptide levels.
Main Results:
- Diabetes mellitus was diagnosed in 29 patients (6.5%), with a mean age of 17 years.
- Patients diagnosed later had a younger age at diabetes onset, higher ferritin levels, and more liver disease.
- Despite iron chelation, high ferritin levels and liver impairment were common; metabolic control was generally poor.
Conclusions:
- Haemosiderosis, liver infections, and genetic factors are critical in diabetes development in thalassaemia major.
- Thalassaemic patients with diabetes face high risks of other endocrine and cardiac complications, necessitating strict monitoring, especially for thyroid function.
