Comparative analysis of mortality patterns and treatment strategies in thalassaemia and sickle cell disease patients: A 12-year study.

This study examined mortality rates among 2475 patients with thalassaemia and sickle cell disease (SCD) per year over 12 years in Greece, recording 335 deaths (27.92/year), with an overall mortality rate of 1.13% per year. The primary aim was to identify causes of death, comorbidities, treatment efficacy and iron overload prevalence. Of the deaths, 239 were attributed to thalassaemia and 96 to SCD. For thalassaemia patients, cardiac failure, hepatocellular carcinoma and sepsis were the leading causes of death, with no neoplasms observed in β+/β+ genotypes. In SCD, sepsis, liver failure and stroke were the predominant causes, with sepsis-related deaths higher in frequently transfused patients. The median age of death was significantly lower in thalassaemia (50 years) compared to SCD (58.49 years, p < 0.001). Differences in comorbidities and treatment effectiveness highlight the need for improved management strategies. Addressing iron overload, optimizing chelation therapy and expanding hydroxyurea use in SCD patients could enhance survival and quality of life. Strengthening treatment protocols and monitoring may reduce mortality, emphasizing the importance of targeted interventions in haemoglobinopathies.
