View clinical trials related to Thalassemia Major.
Filter by:Patients with severe thalassemia (thalassemia major) present with severe anemia that requires life-long transfusion therapy, spleen enlargement that may lead to increased transfusion requirement, and other serious complications as early death, growth retardation, bone deformations and iron overload due to blood transfusions. Splenectomy can significantly reduce transfusion requirement in thalassemia patients, but it is associated with an increased risk of serious complications such as sepsis and thrombosis. Preliminary preclinical and clinical data suggest that JAK2 inhibition, by reducing spleen size, may improve hemoglobin levels, thereby eliminating the need for splenectomy and reducing transfusion requirement and related iron overload.

This is a multicenter observational case-control analysis lasting 12 months aimed at determining the prevalence of pulmonary hypertension (PAH) in patients with Thalassemia Major and Intermedia. The patients will be followed, treated and examined according to the best standard clinical practice dictated by the Italian Society for the study of Hemoglobinopathies (SITE), Thalassemia International Federation (TIF)and the Task Force for Diagnosis and Treatment of Pulmonary Hypertension of European Society of Cardiology (ESC); European Respiratory Society (ERS); International Society of Heart and Lung Transplantation (ISHLT) guidelines.
The proposed research project will continue the application and development of a new method (biomagnetic susceptometry) that measures magnetic fields to determine how much iron is in the liver. The amount of iron in the liver is the best indicator of the amount of iron in the whole body. Measuring the amount of iron in the body is important because either too much (iron overload) or too little iron (iron deficiency) can be harmful. At present, the most reliable way to measure the amount of iron in the liver is to remove a sample of the liver by biopsy, either by surgery or by using a needle which pierces the skin and liver. Iron stored in the liver can be magnetized to a small degree when placed in a magnetic field. In patients with iron overload, the investigators previous studies have shown that magnetic measurements of liver iron in patients with iron overload are quantitatively equivalent to biochemical determinations on tissue obtained by biopsy. In the past the investigators have developed a device to measure the amount of magnetization, which was called a SQUID (Superconducting QUantum Interference Device) susceptometer. This device was validated and in use for over 20 years. The safety, ease, rapidity and comfort of magnetic measurements make frequent, serial studies technically feasible and practically acceptable to patients. The investigators have now developed a new susceptometer, which uses very similar technology to the SQUID, but the investigators believe is more accurate and precise. This study aims to validate this new instrument. The investigators will do prospective, serial studies of the diagnosis and management of patients with iron overload, including thalassemia major (Cooley's anemia), sickle cell disease, aplastic anemia, myelodysplasia, hereditary hemochromatosis, and other disorders.

An Italian Multicentric randomized, open-label therapeutic trial evaluating the efficacy and safety of Neridronate in the treatment of Osteoporosis in patients with Thalassemia Major and Severe Thalassemia Intermedia. Efficacy and safety of the drug will be evaluated measuring at every visit this parameters: - haematological: Haemochrome - blood chemistry: creatinine, BUN, AST, ALT, Ca, P, proteins electrophoresis, total proteins. The prevalence of ectopic calcification and pseudoxantoma elasticum (PXE)-like syndrome and their follow-up will be evaluated at the beginning of the study vs 24 months through physical examination, abdominal echography and fundus oculi examination. During the trial other known risks factors for osteoporosis will be recorded, including prevalence and incidence of bone fractures and, if executed, Polimorphisms COLIA1. At the beginning of the study and at months 12 and 24 morphometry DXA will be performed to evaluate of the presence of bone deformities. Furthermore data regarding QOL and symptom pain will be evaluated trough administration of scale SF-36. At 12 months an intratrial analisis will be performed on efficacy and safety parameters in order to introduce possible amendments to the study design and to decide the prosecution of the trial During the trial all adverse events will be recorded
Background: - Thalassemia major (TM) is a chronic disorder that affects a person s ability to produce hemoglobin, resulting in anemia. Hemoglobin is a component of red blood cells that carries oxygen and nutrients to cells in the body. As a result, individuals require life-long blood transfusions and extensive medical management. Studies have shown that because of its demanding nature, TM might negatively affect an individual s quality of life, sense of self, and social integration, but little is known about affected individuals overall experiences with and perceptions of TM. - TM is caused by a genetic change in the thalassemia gene. The disease is passed to children by parents who carry one copy of the altered thalassemia gene. The parents are called carriers of the condition and have a 25 percent chance of having a child with TM. It is possible to screen for carriers of TM and use this information for pregnancy planning and management. - TM is common among people from South and South East Asia and is an important public health concern in Singapore. More research is needed to explore the lives of people with TM, and the societal perceptions that exist in Singapore about TM. Objectives: - To describe the familial, social, and professional experiences of individuals with TM. - To investigate the social messages being given out about TM in Singapore and the sources of those messages. - To explore the impact of these experiences, perceptions, and social messages on individuals who have TM. - To explore how the experiences and perceptions of individuals who have TM affect their life, sense of self, social integration, and compliance with medical treatment. Eligibility: - Residents of Singapore who are 14 years of age or older, can speak English, and currently have TM. - Parents of individuals with TM who are 14 years of age or older. Parents must be 21 years of age or older, be able to speak English, and have had caregiving responsibilities for their child at some point. Design: - All participants will have a one-time semi-structured interview, followed by a questionnaire to obtain demographic information. - Interviews will be conducted in Singapore and are expected to last for 30 to 90 minutes. - Individuals with TM will be asked about their own perceptions of TM; familial, social, and professional experiences involving TM; and their perceptions of others views and of social messages related to TM. - Parents of individuals with TM will be asked about their experiences in caring for a child with TM, talking to their child about TM, telling people about their child s TM, and interacting with health care providers.
This study aims to investigate the use of amlodipine, a drug that blocks the uptake of calcium into cells, in the prevention and treatment of iron overload in patients with thalassemia major. Since iron uses the same calcium channels to enter the heart, pancreas and other organs, blocking these channels might help to prevent the accumulation of iron in these tissues. The study will follow 10 patients with thalassemia major: 5 will openly receive amlodipine and 5 will serve as controls, not receiving any additional drugs. Patients will be monitored through one year with an additional year of follow up after the group using amlodipine stops its use. Monitoring will occur through the measurement of blood ferritin as well as live and heart T2* by MRI.
This purpose of this study is to understand the differences between people who have a good response to deferasirox (exjade) compared to people who have a poor response to this medication when used for transfusion-dependent iron overload. The hypothesis is that patients with poor responses have physiologic barriers to deferasirox that may include absorption, pharmacokinetics of drug metabolism, hepatic clearance and/or genetic factors.
Changes in chelation treatment and transfusion practices, during the past two decades, have dramatically improved the prognosis of thalassemia major patients.Deferiprone (DFP) has been compared with deferoxamine (DFO), using different schedules of treatment, in the majority of the 13 clinical trials published between 1990 and 2008.No statistically significant difference was shown between these two interventions during, at most, 18 months of treatment.Three randomised trials that compared sequential DFP-DFO treatment versus DFO alone reported controversial results but this could be due to small sample sizes and short treatment duration. In fact, no trial with treatment duration longer than 18 months15, which reported on mortality, adverse events, serum ferritin concentrations, as well as costs has so far been published. This long-term sequential DFP-DFO treatment versus DFP alone treatment trial was conducted to assess the impacts of these chelation treatments on serum ferritin concentrations, mortality, adverse events, and costs in thalassemia major patients.
