Abstract

Thalassemia major (TM) is a hereditary disease caused by defective globin synthesis. Because of the significant increase in life expectancy, these patients are suffering from various health conditions, including endocrinopathies and low bone mineral density. The aim of the present study was to investigate the correlation between clinical and biochemical parameters as well as to identify possible relations in a genotype to phenotype pattern. Sixty-four patients with TM (32 men and 32 women) participated in a cross-sectional study design. The patients were recruited from "Aghia Sofia" Children's Hospital. Clinical and biochemical parameters were evaluated as well as specific mutations were identified. We have found significant correlations between biochemical parameters and iron chelation, hormone replacement treatment as well as TM genotype and hematocrit and T-score. To conclude, the current study showed that clinical parameters of TM patients correlate significantly with both biochemical factors and genotypical patient parameters. Our present study showed that there is a connection between genotype and phenotype as, for example, the identified relation between hematocrit and T-scores and TM-specific mutations. This connection indicates that there is still much more to learn about the role of mutations not only in the disease itself but also in the underlying comorbidities.

Keywords: Biochemical parameters; Mutation frequency; T-score; Thalassemia.
