Filter by:Accumulation of iron in patients with beta thalassemia major causes free radical formation which leads to damage of biological membranes. Sperm DNA damage may result from these generated antioxidants. We aimed at investigating the current DNA damage in the sperms of adult patients with beta thalassemia major and the effect generated by giving antioxidant treatment for 6 months.
This is a multi-center, long-term safety and efficacy follow-up study for subjects with transfusion-dependent β-thalassemia (TDT) who have been treated with ex vivo gene therapy drug product in bluebird bio-sponsored parent clinical studies. After completing the parent clinical study (approximately 2 years), eligible subjects will be followed for an additional 13 years for a total of 15 years post-drug product infusion. No investigational drug product will be administered in this study.
This is a phase I/II study evaluating safety and efficacy of autologous hematopoietic stem cells genetically modified with GLOBE lentiviral vector encoding for the human beta-globin gene for the treatment of patients affected by transfusion dependent beta-thalassemia
This study's goal is to determine the frequency and severity of acute graft versus host disease, to evaluate incidence of primary and secondary graft rejection, to assess event free survival and overall survival, to determine the time to neutrophil and platelet engraftment, to determine the time to immune reconstitution (including normalization of T, B and natural killer (NK) cell repertoire and Immunoglobulin G production), and to establish the incidence of infectious complications including bacterial, viral, fungal and atypical mycobacterial and other infections following CD34+ selection in children, adolescents and young adults receiving an allogeneic peripheral blood stem cell transplant from a family member or unrelated adult donor for a non-malignant disease.
β-thalassemia syndromes are a group of hereditary disorders characterized by a genetic deficiency in the synthesis of beta-globin chains. In recent studies done in β-thalassemia major patients abnormal iron deposition was evident using MRI in brain structures, cortex, putamen, and caudate nucleus . In most of the cases the neurological involvement is subclinical. Cognitive functioning was evaluated in beta thalassemia major, compared with healthy controls, using a neuropsychological battery including tests of abstract reasoning, attention, executive functions, language, constructional/visuospatial skills, and memory. Patients with beta thalassemia major, in particular those showing signs of hemosiderosis, had significantly impaired function in all neuropsychological tests. There was no relationship between cognitive performances and signs of deferoxamine toxicity, deferoxamine dosage, and levels of hemoglobin and ferritin. Event-related potentials (ERPs) are one of the most informative and dynamic methods of monitoring the information stream in the living brain. ERPs are linked in time with a physical or mental event, and are typically extracted from the scalp-recorded electroencephalogram (EEG) by means of signal averaging. ERPs have been used in the assessment of cognitive function in several disorders, including anemia and iron deficiency anemia. However, literature regarding cognitive function and ERP activity in thalassemia patients is extremely limited, especially in adults. The purpose of this study is to evaluate the cognitive and brain function in a group of 60 thalassemia patients and compare the results to healthy controls.
The purpose of this study is to determine whether one dose of the 13-valent pneumococcal conjugate vaccine (PCV13) induces immunological memory in asplenic adults and whether previously administered immunizations with the 23-valent polysaccharide pneumococcal vaccine influence the cellular immune response to PCV13 in this group.
The patient has inherited ß-thalassemia major through the genes. These genes have mistakes in them, so the body cannot make normal red blood cells. Stem cells are made in the bone marrow. They are the earliest form of blood cells. This study is being done to see if the investigators can make the stem cells produce normal red blood cells and hemoglobin. The investigators do this by collecting the stem cells. The genes with mistakes are removed from the cells. These cells are then treated so they have the corrected gene for making normal hemoglobin. These treated cells are given back to the patient through an injection (shot) in the vein. This is also known as gene transfer. In order for the body to accept these cells, the patient will need to receive a low dose of a drug called busulfan. It is a drug that will prepare the body to receive the new stem cells. This study will let the investigators know: - If it is safe to give the patient the treated stem cells - If the treated stem cells will go into the bone marrow without causing side effects. Gene transfer has been used for the past five years. It has been successful in treating many blood disorders. At least 20 patients have received the type of treatment that the patient will get on this study. This treatment for B-thalassemia major was developed here at Memorial Sloan Kettering (MSK). It was studied for a long time in the lab before being given to patients.
This is prospective randomized, double blind study designed to evaluate the use of zoledronic acid in the prevention prevention of bone loss post allogenic BMT done for beta-thalassemia major patients.
Silymarin, a flavonolignan complex isolated from Silybum marianum, has a strong antioxidant, hepatoprotective and iron chelating activities. The present study has been designed to investigate the therapeutic activity of orally administered silymarin in patients with thalassemia major under conventional iron chelation therapy. A 6-month randomized, double-blind, clinical trial was conducted in 140 beta-thalassemia major patients in two well-matched groups. Patients are randomized to receive a silymarin tablet (140 mg) three times a day plus conventional desferrioxamine therapy or the same therapy but a placebo tablet instead of silymarin. Clinical laboratory tests of iron status and liver function are assessed at the beginning and the end of the trial.
β thalassemia is an autosomal recessive hemoglobinopathy and considered as the most widespread genetic mutation. According to the World Health Organization (WHO) between 1.5-7% of the world population are carriers for this disease, and every year 60,000-400,000 birth of new patients are reported. In Israel, the incidence of carriers for β thalassemia is around 20% among the Jewish from Kurdish origin and around 5-10% among the Arab population. β thalassemia is a severe disease which requires many resources, both medical and financial. The disease is expressed by chronic hemolytic anemia which requires regular blood transfusions every 3 weeks. As a result of the blood transfusions and the iron absorption by the digestive tract, those patients suffer from severe hemosiderosis which is the main mortality cause in the disease, mainly in the second decade for life. Daily treatment with iron chelator is required. Moreover, despite the actual treatment, the quality of life of those patients is still low. Therefore the implementation of a prevention program which includes finding an effective and inexpensive way for identifying the β thalassemia carriers is a humanitary and publicly important goal. In β thalassemia carriers, laboratory tests will show hypochromic microcytic anemia. Those findings are similar in iron deficiency anemia, but the RBC number and the RDW are normal in thalassemia carriers. Few researchers tried in the past to determine cutoff point for diagnosis of β thalassemia carriers by different formulas. We used the algorithm SVM (support vector machine) to find a reliable formula that can separate patients with Iron deficiency anemia/ healthy from patients with β thalassemia minor (carriers). This formula can be inserted to any automatic blood counter and search for suspected carriers without deliberately intention and without any further blood test.
