Assessment of Pancreatic Iron Overload in Transfusion Dependent Thalassemic Patients
Advances in the management of transfusion dependent thalassemic patients have improved the survival of these patients. The most important consequence of repeated and frequent transfusions is iron accumulation in vital organs. The magnetic resonance imaging (MRI) is a non-invasive and valid technique for the estimation of iron stores. Despite multiple studies about cardiac and liver MRI T2*, the...
متن کاملEffect of iron overload on furin expression in wild-type and β-thalassemic mice
Furin is a proprotein convertase enzyme. In the liver, it cleaves prohepcidin to form active hepcidin-25, which regulates systemic iron homeostasis. Hepcidin deficiency is a component of several iron overload disorders, including β-thalassemia. Several studies have identified factors that repress hepcidin gene transcription in iron overload. However, the effect of iron overload on furin, a post...
متن کاملHepcidin as a therapeutic tool to limit iron overload and improve anemia in β-thalassemic mice.
Excessive iron absorption is one of the main features of β-thalassemia and can lead to severe morbidity and mortality. Serial analyses of β-thalassemic mice indicate that while hemoglobin levels decrease over time, the concentration of iron in the liver, spleen, and kidneys markedly increases. Iron overload is associated with low levels of hepcidin, a peptide that regulates iron metabolism by t...
متن کاملT2-star (T2*) magnetic resonance imaging for assessment of kidney iron overload in thalassemic patients.
BACKGROUND Improved survival in thalassemic patients has lead to the manifestation of morbidities such as renal dysfunction. This involvement suggests the need for a reliable and non-invasive method to assess the degree of kidney iron overload. We conducted the present study to evaluate the relationship between serum ferritin levels, liver, heart, and kidney MRI gradient echo (T2*) relaxation t...
متن کاملIncreased oxidative stress and iron overload in Jordanian β-thalassemic children.
β-Thalassemia (β-thal) is associated with abnormal synthesis of hemoglobin (Hb). Repeated blood transfusions in patients with β-thal major (β-TM) leads to an enhanced generation of reactive oxygen species (ROS), and subjects patients to peroxidative injury. We studied the antioxidant status and oxidative damage to children with β-thal in Jordan. Samples from 40 children with β-thal and 40 healt...
