Congenital nonspherocytic hemolytic anemia

This study tests whether giving blood transfusions more liberally (when hemoglobin drops to 9 g/dL) versus more restrictively (when it drops to 7.5 g/dL) reduces death and serious complications like heart attack, stroke, or kidney injury in patients aged 70 and older undergoing n…

This study tested a drug called mitapivat (AG-348) in 52 adults with pyruvate kinase deficiency, a rare genetic condition that causes red blood cells to break down too quickly, leading to anemia. The goal was to see if different doses of the drug are safe and help control the dis…

This study tested two different chemotherapy drugs (Treosulfan and Busulfan) given before a stem cell transplant in 106 children with serious non-cancer diseases like immune disorders, metabolic diseases, blood disorders, and bone marrow failure. The goal was to see which drug le…

This study looked at the long-term safety and effectiveness of the drug mitapivat in 90 adults with pyruvate kinase deficiency, a rare genetic blood disorder that causes red blood cells to break down too quickly. Participants had already completed earlier studies of mitapivat and…

This phase 1 trial tested a gene therapy called RP-L301 in 4 people with pyruvate kinase deficiency, a rare inherited blood disorder that causes severe anemia and often requires frequent blood transfusions. The treatment uses the patient's own blood stem cells, which are modified…

This study looked at how often people with certain blood cancers or related conditions have an acquired deficiency of an enzyme called pyruvate kinase, which can cause anemia. Researchers took a single blood sample from 18 participants to measure enzyme activity and check for rel…

This study explored whether low hemoglobin (anemia) is linked to an enlarged heart (cardiomegaly) in children up to 18 years old. Researchers used chest X-rays and echocardiograms to check for heart enlargement in 56 anemic children. The goal was to better understand how anemia a…

This study screened 8,400 people living in Chattogram, Bangladesh to find out how common abnormal hemoglobin types are. Researchers used a blood test called HbA1c capillary electrophoresis to detect conditions like HbE trait. The goal was to understand the prevalence of these inh…

This completed study looked at how often hemoglobin disorders (like thalassemia and sickle cell disease) occur in people visiting a hospital in Chattogram, Bangladesh. Researchers tested blood samples from 760 volunteers using advanced methods to find different hemoglobin types. …

This completed study checked how often inherited blood disorders (hemoglobinopathies) occur in people from Mardan, Pakistan, and nearby areas. Researchers analyzed blood samples from 839 people using special lab tests. The goal was to gather local data to help improve public heal…
