Hemoglobinopathies are inherited disorders that affect haemoglobin and pose a considerable global health challenge. This research addresses the knowledge gap regarding the prevalence of a typical haemoglobin fraction within urban populations by testing the HbA1c test in capillary electrophoresis. Participants will be recruited with careful ethical considerations and informed consent will be obtained. The screening will utilize laboratory techniques to detect abnormal haemoglobin fractions through testing. Statistical methods will be used for data analysis to assess prevalence rates and pinpoint specific haemoglobin variants while considering demographic factors. The project's milestones include planning the study, collecting data (from January 2021 to June 2025), conducting analyses, preparing reports and sharing the findings.
NCT05236764
Patients with medical conditions requiring allogeneic hematopoietic cell transplantation (allo-HCT) are at risk of developing a condition called graft versus host disease (GvHD) which carries a high morbidity and mortality. This is a phase I/II study that will test the safety and efficacy of hematopoietic cell transplantation (HCT) with ex-vivo T cell receptor Alpha/Beta+ and CD19 depletion to treat patients' underlying condition. This process is expected to substantially decrease the risk of GvHD thus allowing for the elimination of immunosuppressive therapy post-transplant. The study will use blood stem/progenitor cells collected from the peripheral blood of parent or other half-matched (haploidentical) family member donor. The procedure will be performed using CliniMACS® TCRα/β-Biotin System which is considered investigational.

NCT06831799
Patients with red blood cell disorders (RBCDs), such as Sickle cell disease (SCD) and Thalassemia, are chronic, life-threatening conditions that can become multi-organ complications over time, and are likely at an increased risk of COVID-19-related complications. Patients at the highest risk include the elderly (\>50 in our population), those with a history of respiratory or cardiac disease and those with other comorbidities. Several patients affected by RBCDs undergo splenectomy as therapeutic option to improve their level of hemoglobin concentration. Splenectomized patients, or in the case of SCD with functional hyposplenism, are more vulnerable to bacterial infections / superinfections after viral infection. Acute pulmonary syndrome (ACS) is the main cause of morbidity in SCD in middle-high income countries, and is often triggered by infectious events. Currently, there is no literature on the subject. Thus, any recommendation available comes from the experience gained with previous Coronaviruses infections. Accordingly, the correct treatment and management of infection by Coronavirus SARS-COV-2 (COVID-19) in patients affected by RBCDs may be challenging given the rapid spread of the pandemic and limited literature so far, especially in some countries. Accordingly, there is an urgent need to pool evidence in a unique repository on patients affected by RBCDs and COVID-19 in order to reach critical numbers to facilitate the medical decision making process across Europe. The Registry on patients with rare RBCDs and COVID-19 is an initiative conceived in the core of the European Reference Network on Rare Hematological Diseases (ERN-EuroBloodNet, FPA 739541, www.eurobloodnet.eu) aiming at supporting medical practice of COVID-19 in these patients by gathering evidence on pediatric and adult COVID-19 confirmed cases in RBCDs across Europe.

NCT01850108
Allogeneic blood or marrow transplantation (alloBMT) is a curative therapy for a variety of hematologic disorders, including sickle cell disease and thalassemia. Even when it is clear that alloBMT can give to these patients an improvement in their disease, myeloablative transplants have important toxicities and mortalities associated. The lack of suitable donors continues to be a limit to access to transplantation. Substantial progress has been made recently in the development of pre-treatment regimens that facilitate the sustained engraftment of donor marrow with reduced toxicity. Most of these regimens incorporate highly immunosuppressive drugs, which allow the reduction or elimination of myeloablative agents or total body irradiation without endangering the sustained engraftment of HLA-identical allogeneic stem cells. Preliminary results of non-myeloablative allogeneic stem cell transplantation suggest that the procedure can be performed in patients who are ineligible for myeloablative alloBMT, and that sustained remissions of several hematologic malignancies can be obtained.
NCT02065869
This study will evaluate pediatric patients with malignant or non-malignant blood cell disorders who are having a blood stem cell transplant depleted of T cell receptor (TCR) alfa and beta cells that comes from a partially matched family donor. The study will assess whether immune cells, called T cells, from the family donor, that are specially grown in the laboratory and given back to the patient along with the stem cell transplant can help the immune system recover faster after transplant. As a safety measure these T cells have been programmed with a self-destruct switch so that they can be destroyed if they start to react against tissues (Graft versus host disease).
NCT00000588
To demonstrate the safety and effectiveness of orally-administered pyridoxal isonicotinoyl hydrazone (PIH) for the chronic treatment of iron overload.
NCT03609814
Fludarabine and clofarabine are chemotherapy drugs used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of clofarabine and fludarabine 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 clinical and individual factors cause changes in clofarabine and fludarabine drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
NCT00102245
This study will examine blood for factors that may cause or prevent diseases involving iron or red blood cells. Iron is an important nutrient for human health that is needed to produce red blood cells. Red blood cells carry oxygen to body tissues.
