Filter by:The purpose of this study is determination of the efficacy of combination of hydroxyurea with L-carnitine or magnesium in improving hematologic parameters and cardiac status in patients with β-thalassemia intermedia in comparison with hydroxyurea alone .
Myocardial iron overload is the leading cause of death in patients with beta-thalassemia major (TM). Therapy with deferoxamine (DFO) combined with deferiprone (DFP) reduces myocardial iron and improves cardiac function. However, the prognosis for TM patients with established cardiac disease switched from DFO monotherapy to combined DFP/DFO chelation is unknown. Twenty-eight TM patients with cardiac disease were enrolled in a prospective study lasting 42±6 months. Fifteen (9 high-ferritin and 6 low-ferritin) were placed on DFP/DFO (DFP, 75 mg/kg t.i.d.; DFO, 40-50 mg/kg over 8-12 h at night 5-7 d/wk), while 13 (5 high- and 8 low-ferritin) received DFO alone. No cardiac events were observed among high-ferritin patients on combination therapy, whereas 4 cardiac events (p=0.0049), including three deaths, occurred in high-ferritin patients on DFO monotherapy. These findings demonstrate that in TM patients with well-established cardiac disease combined iron-chelation therapy with DFP/DFO is superior to DFO monotherapy.
The purpose of this study is to evaluate the safety and tolerability of HQK-1001 administered daily for 8 weeks in subjects with beta thalassemia intermedia
Hypercoagulable state is well recognized in patients with β-thalassemia. Evidences of hypercoagulability include abnormal expression of phosphatidylserine on red blood cell (rbc) surface and consequent increased platelet activation and thrombin generation. In addition, a reduction of anticoagulants i.e. proteins C and S and antithrombin (AT) was demonstrated. However, coagulable state in patients with β-thalassemia following stem cell transplantation (SCT) has not been characterized.
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.
The primary objective is to determine the feasibility of attaining acceptable rates of donor cell engraftment (>25% donor chimerism at 180 days) following reduced intensity conditioning (RIC) regimens in pediatric patients < 21 years receiving cord blood transplantation for non-malignant disorders.
This study will summarized the clinical and laboratory data and the outcome of all the patients suffering from Sickle Cell Anemia (Including Sickle cell thalassemia) admitted to the pediatric ward.
This study intends to analyze the clinical characteristics of teenagers admitted to pediatric wards due to organic illness and non organic diagnosis, including patients suffering from chronic diseases and comorbidity.
Since 1987, a screening for β Thalassemia in pregnant women is carried on in northern Israel, and from 1999 all the samples were tested also for Hgb S, Hgb C, Hgb D, Hgb O Arab and others. In this study, the investigators intend to summarize the results of this preventive program aiming to detect couples at risk for having offspring with Thalassemia or SCA, the compliance regard to genetic counseling and prenatal diagnosis and the incidence of new affected babies born.
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.
