NCT02824471
'Sickle-shaped' anemia was first clinically described in the US in 1910, and the mutated heritable sickle hemoglobin molecule was identified in 1949. The pathophysiology of SCD is a consequence of abnormal polymerization of sickle hemoglobin (HbS) and its effects on red cell membrane properties, shape, and density, and subsequent critical changes in inflammatory cell and endothelial cell function. Our goal is to understand the impact of CMA abnormalities in SCD, by interrogating a number of recognized interactions in a range of clinical phenotypes. To date, correlative studies in SCD, by us and others, have range between clinical reports, based on tests, interventions, and chart review of individuals or groups of individuals and, at the other extreme, identification of functional gene polymorphisms based on population studies. The investigators wish to augment these studies through a systematic examination of cellular membrane properties and activation status. Of hematologic disorders, SCD may be unusually susceptible to such an examination.

NCT03948516
Sickle cell disease is very common in Nigeria. Early diagnosis is important to prevent or reduce serious complications from the disease and to enable children stay healthy. To this end, the investigators would like to test a new, simple and quick device called the HemeChip to determine if it can detect whether or not someone has sickle cell disease. The investigators will compare the results obtained with the HemeChip with a standard method of diagnosing sickle cell disease known as Isoelectric focusing (IEF) or High Performance Liquid Chromatography (HPLC).If the investigators show that the new device can differentiate between children who have sickle cell disease and those who don't as successfully as the IEF or HPLC, they estimate a sharp increase in the use of this device in many countries especially in Africa due to its lower cost
