A large scale survey of haemoglobinopathies and thalassaemia has been carried out in China, involving 900,000 people in 28 provinces. It has resulted in the finding of many new variants and some interesting cases of thalassaemia, and in a study on the chemical structure of abnormal haemoglobins and DNA analysis of thalassaemia. We report here data on haemoglobin disorders in the Chinese, mainly...
BACKGROUND Iron may damage sarcomeric proteins through oxidative stress. We explored the left ventricular (LV) torsional mechanics in patients with beta-thalassaemia major and its relationship to myocardial iron load. Using HL-1 cell and B6D2F1 mouse models, we further determined the impact of iron load on proteolysis of the giant sarcomeric protein titin. METHODS AND RESULTS In 44 thalassaem...
Non-transfusion-dependent thalassaemia (NTDT) refers to all thalassaemia disease phenotypes that do not require regular blood transfusions for survival. Thalassaemia disorders were traditionally concentrated along the tropical belt stretching from sub-Saharan Africa through the Mediterranean region and the Middle East to South and South-East Asia, but global migration has led to increased incid...
The study concerned the identification of the beta-thalassaemia mutations that were present in 24 patients with beta-thalassaemia major who were transfusion dependent. The application of a modified polymerase chain reaction, the amplification refractory system (ARMS) was found to be an effective and rapid method for the identification of the beta-thalassaemia mutations. Six different mutations ...
Haemoglobin Variants are genetic haematological abnormalities affecting millions of people all over the world. Hb E, Hb S and βthalassaemia are the most prevalent Hb variants in NorthEastern region of India. Identification of these disorders is immensely important to prevent the occurrence of serious haemoglobin disorders. The objective of the study was to diagnose and find the occurrence of Hb...
Thalassaemia and sickle cell disease (SCD) represent the most common forms of hereditary haemolytic anaemia and result from a partial or complete lack of synthesis of one of the major alpha- or beta-globin chains of haemoglobin A or from a single amino acid mutation (beta(6Glu-->Val)) of the beta-globin chain respectively. Although they have different pathophysiologies, patients with these cond...
BACKGROUND The UK Thalassaemia Register records births, deaths and selected clinical data of patients with thalassaemia who are resident in the UK. A study of survival and causes of death was undertaken which aimed to include the possible impact of T2* cardiovascular magnetic resonance (CMR). METHODS The Register was updated to the end of 2003, copies of death certificates were obtained, and ...
Thalassaemia major is a classical example of a disease that can be prevented by prenatal diagnosis. In Romania there are currently 300 patients with thalassaemia major under the management of specialized institutions. Prenatal diagnoses of thalassemia have offered a new dimension to the prevention of this disease, but in order to implement prenatal diagnosis, knowledge of mutations and of their...
