Background: Beta-thalassemia major is the most common chronic hemolytic anemia among children and adolescents across the world. Several studies have demonstrated that thalassemic patients who have preserved left ventricle systolic function could still have subtle systolic dysfunction. Among patients with beta-thalassemia, early detection of transfusion-induced myocardial iron loading and its intervention with aggressive chelation therapy may delay or reverse heart failure.

Iatrogenic iron overload, which is not uncommon in patients undergoing long-term haemodialysis, arises from a combination of multiple red cell transfusions and parenteral iron infusions that are administered to maintain a haemoglobin concentration of approximately 10 g/dL. Although iron overload due to genetic haemochromatosis is conventionally managed by phlebotomy, patients with haemoglobinopathies and chronic transfusion-induced iron overload are treated with iron-chelation therapy. However, the management of iron overload in our patient who presented with hepatic dysfunction and immunosuppressive drug-induced mild anaemia in the post-renal transplant setting posed unique challenges.

The VIII ICET-A International Symposium was held in Muscat (Sultanate of Oman) on the 20th of December, 2014. The symposium included four sessions on a wide range of topics covering growth disorders and endocrine complications in thalassaemia. Despite the fact that endocrine complications are very common in multi-transfused thalassaemia patients a recent survey conducted by the International Network of Clinicians for Endocrinopathies in Thalassemia and Adolescent Medicine (ICET-A) in 2014 in Acitrezza (Catania, Italy) showed that the major difficulties reported by hematologists or pediatricians experienced in thalassaemias or thalassaemia syndromes in following endocrine complications included: Lack of familiarity with medical treatment of endocrine complications, interpretation of endocrine tests, lack of collaboration and on-time consultation between thalassaemic centres supervised by haematologists and endocrinologists.

Many patients with bone marrow failure syndromes need frequent transfusions of red blood cells, and most of them eventually suffer from organ dysfunction induced by excessively accumulated iron. The only way to treat transfusion-induced iron overload is iron chelating therapy. However, most patients have not been treated effectively because daily/continuous administration of deferoxamine is difficult for outpatients. Read More

Beta-thalassemia is a genetic, red blood cell disorder affecting the beta-globin chain of the adult hemoglobin gene. This results in excess accumulation of unpaired alpha-chain gene products leading to reduced red blood cell life span and the development of severe anemia. Current treatment of this disease involves regular blood transfusion and adjunct chelation therapy to lower blood transfusion-induced iron overload. Read More

We postulated that patients with hereditary hemochromatosis (HH) absorb increased quantities of lead, as do iron-deficient subjects. To test this hypothesis, whole blood lead concentration ([blood Pb]) was quantified by atomic absorption spectrometry in HH homozygotes (n = 44), obligate heterozygotes (n = 19), normal control subjects (n = 33), and abnormal controls, with transfusion-induced iron overload (n = 8). HH homozygotes had higher [blood Pb] than did normal control subjects (5. Read More

Transfusion-induced hemosiderosis is a serious and potentially life-threatening complication for some patients with sickle cell anemia. The use of high-dose intravenous deferoxamine (DFO) has become widespread in spite of a paucity of published data on safety and efficacy. We report a randomized double-blind study of the dose-response relationship of intravenous DFO in six subjects with sickle cell anemia and severe transfusion-induced hemosiderosis (serum ferritin 4100 to 14,176 ng/ml).

The heme oxygenase inhibitor tin (Sn4+)-mesoporphyrin, administered to two 17-year-old Crigler-Najjar type I patients during a 400-day study to lower plasma bilirubin levels, also produced changes, beginning approximately 50 days after initiation of treatment, in hematological and iron metabolism indices consistent with the development of iron deficiency anemia. These indices were responsive to iron supplementation and reverted to normal after termination of inhibitor treatment. Tin-mesoporphyrin enhances biliary heme excretion and inhibits intestinal heme oxygenase when administered orally or parenterally; the changes in blood indices could thus reflect, in part, blockade of heme catabolism and therefore of uptake of heme-derived iron, by intestinal epithelium.
