Active clinical trials for "Thalassemia"

Sickle cell disease (SCD) is an inherited blood disorder associated with acute illness and organ damage. In high resource settings, early screening and treatment greatly improve quality of life. In low resource settings, however, mortality rate for children is high (50-90%). Low-cost and accurate screening techniques are critical to reducing the burden of the disease, especially in remote/rural settings. The most common and severe form of SCD is sickle cell anemia (SCA), caused by the inheritance of genes causing abnormal forms of hemoglobin (called sickle hemoglobin or hemoglobin S) from both parents. The asymptomatic or carrier form of the disease, known as sickle cell trait (SCT), is caused by the inheritance of only one variant gene from one of the parents. In areas such as Nepal, β-thalassemia (another inherited blood disorder) and SCD are both prevalent, and some combinations of these diseases lead to severe symptoms. The purpose of this study is to determine the accuracy of low-cost point-of-care techniques for screening and detecting sickle cell disease, sickle cell trait, and β-thalassaemia, which will subsequently inform on feasible solutions for detecting the disease in rural, remote, or low-resource settings. One of the goals of the study is to evaluate the feasibility of techniques, such as the sickling test with low-cost microscopy and machine learning, HbS solubility test, commercial lateral-flow assays (HemoTypeSC and Sickle SCAN), and the Gazelle Hb variant test, to supplement or replace gold standard tests (HPLC or electrophoresis), which are expensive, require highly trained personnel, and are not easily accessible in remote/rural settings. The investigators hypothesize that: an automated sickling test (standard sickling test enhanced using low-cost microscopy and machine learning) has a higher overall accuracy than conventional screening techniques (solubility and sickling tests) to detect hemoglobin S in blood samples the automated sickling test can additionally classify SCD, SCT and healthy individuals with a sensitivity greater than 90%, based on morphology changes of red blood cells, unlike conventional sickling or solubility tests that do not distinguish between SCD and SCT cases Gazelle diagnostic device can detect β-thalassaemia and SCD/SCT with an overall accuracy greater than 90%, compared with HPLC as the reference test

Randomized controlled trial was conducted in post-splenectomy patients aged >12 years. Subjects are randomly assigned to two groups (zinc and placebo). 1.5 mg/kg/day (max 50 mg/day) of Zinc is administered.

Hematopoietic stem cell transplantation is currently the only way to cure thalassemia, one of its main obstacles is the rejection after transplantation, chimerism continued to decline, which eventually lead to transplant failure. chimerism is a key indicator of the succession of immune response, which is a key indicator for predicting the failure of hematopoietic stem cell transplantation and provides an important basis for early detection of rejection. Transplantation of continuous chimerism can detect early unstable chimeras and rejection.The chimerism rates after transplantation were continuously monitored using fluorescence labeled multiplex PCR amplification of short tandem repeats (STR-PCR) ,and then follow our STR different rates for early interventional therapy to prevent further reduction in chimerism leading to lead to graft failure.

Splenectomized thalassemia major subjects were provided with PCV pneumococcal vaccine (Prevenar 13®) at the start of the trial, following which they were randomly assigned to 2 groups (zinc and placebo group). After 8 weeks, the subjects received PPV pneumococcal vaccine (Pneumovax®). Zinc syrup was provided to the zinc group at a dose of 1.5 mg/kg/day (maximum of 50 mg/day). Pneumococcal IgG examinations were conducted at the start of the trial and after 12 weeks.

Iron overload is well study in Thalassemia patients and it's not only related to blood transfusions, since intestinal iron absorption is also increased in those patients. Sickle cell patients didn't develope significant clinical symptoms and signs of iron overload in spite frequent transfusions. The purpouse of this study is to assess the iron overload in Sickle cell anemia and Sickle cell Thalassemia patients using clinical parameters and cardiac T2*MRI in order to determine the cardiac and liver iron.

The CENTAurus trial is a prospective clinical study designed to address systematically some of the relevant endocrine complications in an iron overloaded thalassemic population, primary objective being the assessment of the effect of deferasirox therapy on glucose metabolism/homeostasis. Other endocrine parameters complementary or supportive to the primary objective will be assessed and analyzed during this study. A number of lab parameters related to other axes of the endocrine system will be collected and analyzed.

This study aims to: Assess the cognitive function in children with beta thalassemia Evaluate the fatigue in beta thalassemic children Assess the health related quality of life measures in children with beta thalassemia.

The primary objective is to assess the prevalence and genotypes of HCV infection in thalassemia major and thalassemia intermediate patients who have received blood transfusion in the Department of Medicine, Faculty of Medicine Siriraj Hospital. The secondary objective is to identify the effect of HCV infection as well as the risk factors of advanced liver disease and liver cirrhosis in these patients The third objective is to identify the role of serum HA level and fibrotest in the prediction of cirrhosis in these patients.

Thiotepa is a chemotherapy drug used extensively in bone marrow transplantation. Thiotepa is a prodrug that undergoes metabolic conversion in the liver by CYP2B6 and CYP3A4 to its primary active metabolite, triethylene phosphoramide (TEPA). The goal of this study is to determine what causes some children to have different drug concentrations of thiotepa and TEPA in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that certain clinical and genetic factors cause changes in thiotepa and TEPA drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.

This is a non-interventional post-authorization safety study (PASS) employing a cross sectional design to evaluate the effectiveness of the additional risk minimization measures (aRMMs) for REBLOZYL. A survey will be used to measure the knowledge and comprehension of the REBLOZYL aRMMs among European Economic Area (EEA) based healthcare professionals (HCPs). The PASS will be conducted among HCPs in a representative sample of EEA countries where REBLOZYL is commercially available, potentially including Austria, Germany, Italy, Norway, Sweden, the Netherlands, Poland, and Spain. Additional EEA countries may be included, as needed, based on commercial availability and reimbursement status.
