The present study was undertaken to evaluate glutathione and its related enzymes in beta-thalassaemia major and to elucidate the effect of splenectomy on glutathione metabolism. The study includes three groups, those are: healthy individuals (n= 35) taken as control, a group of beta-thalassaemia major children with intact spleen (n= 29) and a group of splenectomized beta-thalassaemia major chil...
Nineteen children and adolescents receiving repeated transfusions and subcutaneous desferrioxamine treatment were investigated in an attempt to quantitate iron overload non-invasively. Before patients were started on desferrioxamine individual relationships were correlated for 12 to 36 months between transfused iron, absorbed iron estimated gastrointestinally, and increasing serum ferritin conc...
OBJECTIVE To provide a synopsis of current thalassaemia major patient care in Hong Kong. DESIGN Retrospective study. SETTING All haematology units of the Hospital Authority in Hong Kong. PATIENTS All patients with thalassaemia major with regular transfusion. RESULTS To date, there were 363 thalassaemia major patients under the care of the Hospital Authority. Prenatal diagnosis has helpe...
The provision of a prenatal diagnosis service for thalassaemia is becoming more demanding. In an ethnically-diverse community, the number of mutations has increased. Requests for prenatal testing continue to come at advanced stage in pregnancy, often without the underlying mutation having been identified. Although controls are included in PCR assays, errors can still occur. The alternative to D...
A hospital-based survey was undertaken to investigate the relationship between the incidence and severity of malaria infection and various red cell disorders in Myanmar. The mean parasitaemia levels of patients with alpha- or beta-thalassaemia trait or with severe glucose-6-phosphate dehydrogenase (G6PD) deficiency were lower than those of individuals with normal haemoglobin AA or with heterozy...
This study investigated the prevalence of iron-deficiency anaemia, glucose-6-phosphate dehydrogenase (G6PD) deficiency and β-thalassaemia trait among Arab migrating nomad children in southern Islamic Republic of Iran. Blood samples were analysed from 134 schoolchildren aged < 18 years (51 males, 83 females). Low serum ferritin (< 12 ng/dL) was present in 17.9% of children (21.7% in females and ...
Alpha-thalassaemia is a very rare disease in Northern Europe in contrast to hereditary spherocytosis that is associated with red blood cell membrane defects. We report here alpha-thalassaemia case who was also found to bear the erythrocyte membrane protein 4.2 gene mutations. mRNA relative quantification of red cell membrane protein genes in a Polish patient with alpha-thalassaemia trait indica...
In the south-east of Sicily 23 children from 14 unrelated families have been diagnosed as suffering from haemoglobin Lepore. Such a high incidence shows that Sicily is an important focus of haemoglobin Lepore. The results of haematological and biosynthetic studies in 18 carriers of Hb Lepore and in five double heterozygotes for Hb Lepore and beta-thalassaemia are presented. In the carriers the ...
α-Thalassaemia is the most common inherited disorder of Haemoglobin (Hb) production in southeast Asia, resulting from deficient synthesis of the α-globin chain component of the haemoglobin molecule due to deletion or inactivation of one or more of the normal four alpha-chain genes. The severity of the condition depends on the number of genes inactivated. The severest form is Hb Barts hydrops fe...
BACKGROUND In the UK about 4.5% of the population carry cystic fibrosis, whilst in the inner city areas an even higher proportion carry one of the haemoglobin disorders such as thalassaemia. Couples who both carry the same recessive disorder have a 1 in 4 risk of an affected child in every pregnancy. OBJECTIVES To assess GPs' confidence in their ability to provide initial prenatal advice for ...
