Hepatitis C virus (HCV) infection is highly prevalent in thalassemic patients, and this may decrease the serum antibody response to hepatitis B virus (HBV) vaccine. There is also some alteration of the immune system in multi-transfused thalassemic patients, as a consequence of iron overload. We investigated whether HCY infection may reduce the effectiveness of HBY vaccine in multi - transf...

Certain red blood cell (RBC) disorders, including thalassemia, have been associated with an innate protection against malaria infection. However, many in vitro correlative studies have been inconclusive. To better understand the relationship between human RBCs with thalassemia hemoglobinopathies and susceptibility to in vitro infection, we used an in vitro coculture system that involved biotin ...

When prepared for transplantation with busulfan (BU) 14 mg/kg and cyclophosphamide (CY) 120 to 160 mg/kg, patients with thalassemia in risk class 3, aged younger than 17 years, who receive transplants from HLA-identical donors, had a 30% incidence of transplant rejection with recurrence of thalassemia. This, relatively poor, outcome was ascribed to insufficient immune suppression or to inadequa...

Genes for two lethal diseases, thalassemia and sickle cell anemia, are favored by evolution because, in their heterozygous form, they protect against cerebral malaria. Rosette formation, the binding of uninfected red cells (RBCs) to Plasmodium falciparum-infected RBCs (PRBCs), has previously been found to be associated with cerebral malaria, the most important severe manifestation of P falcipar...

Antioxidant phytochemicals are investigated as novel treatments for supportive therapy in beta-thalassemia. The dietary indicaxanthin was assessed for its protective effects on human beta-thalassemic RBCs submitted in vitro to oxidative haemolysis by cumene hydroperoxide. Indicaxanthin at 1.0-10 microM enhanced the resistance to haemolysis dose-dependently. In addition, it prevented lipid and h...

To define the quality and relative quantity of beta and alpha messenger RNA in human nonthalassemic and thalassemic reticulocytes, intact cells were incubated with [(35)S]methionine. The relative amounts of beta- and alpha-nascent chains on polysomes of different sizes were measured by tryptic digestion of pooled polysomes and by determination of the specific activities of beta and alpha peptid...

Thalassemia is a hematological disorder caused by gene mutation that leads to defective synthesis of hemoglobin complex. One the complications thalassemia hypocalcemia which presented with paresthesia, muscle spasm, low-serum calcium, and intracranial calcification. Hypocalcemia can affect thalassemic patients via various mechanisms. Blood transfusion-related transfusion-independent iron overlo...
