Background: With transfusions and chelation therapy, the prognosis for transfusion-dependent beta thalassaemia has changed from being fatal in early childhood to a chronic disorder with prolonged survival.
Design And Methods: In this historical prospective study, we present survival, causes of death and mortality ratios compared to the general population in 1044 Greek patients with transfusion-dependent beta thalassaemia.
Results: At the age of 50years, the overall survival was 65.0%, while the cardiac death-free survival was 77%. Birth cohort had a significant effect on survival (P<0.001) with a negative trend towards past decades. The standardised mortality ratio (standardised for sex and ages 20-40years) compared to the general population improved significantly from 28.9 in 1990-1999 to 13.5 in 2000-2008, while the standardised cardiac mortality ratio reduced from 322.9 to 106.6, respectively.
Conclusions: Survival in thalassaemia has dramatically improved over the last twenty years but mortality remains significantly increased, compared to the general population.

Background: Thalassemia is one of the most common congenital hemoglobinopathies globally. Regular red blood cell (RBC) transfusion is of paramount importance in the treatment of thalassemia patients. However, this practice increases the risk of alloimmunization.

Sabah has the highest prevalence of β-thalassemia in Malaysia, with the Filipino β-deletion as the predominant mutation. Patients with the homozygous Filipino β-deletion exhibit phenotypic heterogeneity due to various genetic modifiers, yet the effects of these modifiers on the clinical phenotype remain poorly understood. This study investigated the effects of the coinheritance of α-thalassemia, I-γ rs7482144, rs766432, and 5'HS4 rs16912979 polymorphisms on the clinical phenotype of homozygous Filipino β-deletion patients in Sabah.

Background: Many patients with β-thalassaemia die prematurely due to iron overload. In this study, we aim to evaluate the efficacy and safety of the triple combination of deferoxamine, deferasirox and deferiprone on iron chelation in patients with transfusion-dependent β-thalassaemia with very high iron overload.
Methods: This open-label, randomised, controlled clinical trial was conducted at Colombo North Teaching Hospital, Sri Lanka.

Beta-thalassemia is a severe, hereditary blood disorder characterized by anemia, transfusion dependence, reduced life expectancy, and poor quality of life. Allogeneic transplantation of hematopoietic stem cells (HSCs) is the only curative treatment for transfusion-dependent β-thalassemia, but a lack of compatible donors prevents the use of this approach for most patients. Over the past 20 years, the rise of gene therapy and the development of lentiviral vectors and genome-editing tools has extended curative options to a broader range of patients.
