Physiology and Pathologies Linked to Human Splenic Function : Direct and Ex-vivo Perfusion Explorations
Human splenic physiology remains poorly understood due to lack of functional exploration. However, through its ability to recognize alterations or modifications in circulating cells and to trigger an innate and adaptive response in response to these anomalies, the spleen plays a central role in several diseases affecting blood cells, directly …
Enablers and Barriers to Hydroxyurea Use for Sickle Cell Disease Jamaica
Sickle cell disease (SCD) is associated with a lifetime of medical and socio-behavioural complications that require coordination of care from multidisciplinary teams. Access to adequate care for SCD is important as inadequate access can contribute to increased acute care utilization, disjointed care delivery, and earlier mortality for many SCD patients. …
Data Collection Study of Patients With Non-Malignant Disorders Undergoing UCBT, BMT or PBSCT With RIC
This is a data collection study that will examine the general diagnostic and treatment data associated with the reduced-intensity chemotherapy-based regimen paired with simple alemtuzumab dosing strata designed to prevented graft failure and to aid in immune reconstitution following hematopoietic stem cell transplantation.
Study of Erythrocyte Parameters and Hypercoagulability in Sickle Cell Disease (SCD-TGA)
Sickle cell disease (SCD) is an inherited haemoglobinopathy disorder caused by mutations in HBB gene with amino-acid substitution on β globin chain. The consequence is synthesis of altered haemoglobin S (HbS) which polymerises in red blood cell (RBC) at deoxygenated state. SCD is associated with chronic haemolytic anaemia, vaso-occlusive crisis …
Hydroxyurea Exposure Limiting Pregnancy and Follow-Up Lactation
The purpose of this research study is to document and understand the effects of hydroxyurea exposure for women with SCD and their babies, during both gestation and lactation.
Arterial Function Parameters and Transcranial Doppler Velocity in Paediatric Patients With Sickle Cell Disease
Structural and functional changes in arteries are increasingly being recognized as significant features of sickle cell disease. This study aims to determine whether there are differences in arterial function parameters between children with sickle cell disease with normal and abnormal transcranial Doppler velocity. After informed consent is obtained, participants will …
Biological, Genetic and Environmental Involved in the Complications of Sickle Cell Disease
The objective of the study is to refine our knowledge on the physiopathology of the symptoms and the complications for the patients affected by a drepanocytic syndrome. The establishment of risk factors and indicators of severity will allow to target better the patients requiring an adequate strategy in order to …
Brain Structure and Neurocognitive Development in Sickle Cell Disease; a Longitudinal Cohort Study (BRICK Study)
Sickle cell disease (SCD) is an autosomal recessive red blood cell blood disorder. One especially vital organ affected in SCD is the brain. Individuals with SCD have an increased risk of both overt cerebral infarctions and silent infarctions. The latter are brain lesions without apparent neurological sequelae. Since cortical neurons …
Observational Study to Deeply Phenotype Major Organs in Sickle Cell Disease After Curative Therapies
Background:People with sickle cell disease (SCD) have problems with their heart, brain, kidneys, liver, and lungs as they age. These problems may improve after transplant. Researchers want to learn how and why this happens.Objective:To study the benefits of treatments that are intended to cure SCD.Eligibility:People aged 18 and older with …
Lung Ultrasound in Pediatric Acute Chest Syndrome
Sickle-cell disease is a common disease with serious complications, in particular acute chest syndrome (ACS), which can be life threatening. The pathophysiology of ACS is poorly understood, but alveolar hypoventilation appears to play an important role. Pulmonary ultrasound is increasingly used in pediatrics to diagnose ACS. The management of ACS …
