Anemia due to enzyme disorder

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 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…
