Filter by:To determine the prevalence, genetic and environmental determinants, and potential clinical, personal, and societal impact of iron overload and hereditary hemochromatosis, in a multi-center, multiethnic, primary care-based sample of 100,000 adults. The study is conducted by the Division of Epidemiology and Clinical Applications of the NHLBI, the Division of Blood Diseases and Resources of the NHLBI, and the Ethical, Legal, and Social Implications (ELSI) Research Program of the NHGRI.
Patients with beta-thalassemia (Cooley's Anemia) continue to suffer from the transfusion-induced iron overload due to the inadequacies of current iron-chelation therapy. Compliance with the use of the only FDA-approved drug for removing excess iron from patients (Desferal) continues to be a major problem despite convincing evidence that it markedly reduces morbidity and prolongs life. The full potential of iron-chelation therapy will not be realized until an orally-effective drug is available. This small trial is testing the premise that a combination of drugs as a new approach to iron chelation therapy may reduce side effects and increase efficacy. If both drugs can be given orally, there may be a better chance of finding a suitable alternative to Desferal. Several combinations of experimental iron chelating drugs are being used in this trial.
Iron overload (hemochromatosis) is a condition which causes the intestines to take too much iron into the body from food or pills. The extra iron can build up in the liver, heart, joints, pancreas, sex organs, and other organs. Patients with iron overload can feel well initially, but the iron will eventually damage organs and may lead to an early death. The condition is believed to be passed down from generation to generation. Many studies have been conducted on the condition as it affects Caucasian Americans, few have addressed the condition in African Americans. Researchers believe it is important to find out as much as possible about the iron overload in African Americans. The goal of this study is to determine the pattern of inheritance of primary iron overload in African American families and to identify the genetic defect causing the condition. The study will use various tests from simple blood testing (transferritin saturation and serum ferritin levels) to complex genetic tests (segregation analysis and polymerase chain reaction [PCR]). The tests will help researchers deterimine iron levels in the blood, presence of antigens that may help trace inheritance, and detect changes in genes that are known to cause iron overload in Caucasians. The study may not directly benefit the patients participating in it. However, this study may lead to improved methods to diagnose iron overload in the African American population as a whole.
The purpose of the TCRN is to accelerate research in the management of thalassemia, standardize existing treatments, and evaluate new ones in a network of clinical centers in North America. The emphasis will be on clinical trials that help identify optimal therapy. Therapeutic trials may involve investigational drugs, drugs already approved but not currently used, and drugs currently used.
To determine whether deferoxamine prevented the complications of transfusional iron overload.
To demonstrate the safety and effectiveness of orally-administered pyridoxal isonicotinoyl hydrazone (PIH) for the chronic treatment of iron overload.
