Cerebral Blood Transit in Sickle Cell Anemia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Sickle cell anemia (SCA) patients upregulate cerebral blood flow to compensate for decreased arterial oxygen content. Such hyperemic conditions can manifest as venous hyperintense signal on arterial spin labeling (ASL) MRI, which may reflect faster capillary blood transit, altered oxygen extraction fraction (OEF), and infarct risk ...

Analysis of Common Alpha-Globin Gene Abnormalities and Their Effects as Genetic Modifiers in Thai Children With β-Globin Gene Abnormalities

Anemia
Beta-thalassemia exhibits a broad phenotypic range influenced by the severity of HBB mutation and various genetic modifiers. One of the most essential modifiers is the coinheritance of α-globin gene mutation.

Heterozygous Beta‐Thalassaemia in Pregnancy: Two Rare Causes of Severe Fetal Anemia Requiring Intrauterine Blood Transfusions

Prenatal Diagnosis, EarlyView.
ABSTRACT Aim In this article, we present two cases of severe fetal hemolytic anemia based on a beta‐thalassaemia trait inherited from a single parent. Results These cases, presented at 20 and 28 weeks' gestation, necessitated intra‐uterine blood transfusions.

Diagnosis and Management of Prenatal Hereditary Pyropoikilocytosis

Prenatal Diagnosis, EarlyView.
ABSTRACT Hereditary pyropoikilocytosis (HPP) is a severe hemolytic anemia caused by variants in SPTA1, SPTB, and EPB41. These weaken horizontal interactions in the erythrocyte cytoskeleton, causing membrane fragmentation and splenic sequestration. It will readily cause fetal anemia and often hydrops fetalis. Prenatal diagnosis requires first ruling out

In Utero HSC Transplantation for Sickle Cell Disease: A Potential Therapeutic Approach That Overcomes Complications of Current Therapies

Prenatal Diagnosis, EarlyView.
ABSTRACT Sickle cell disease (SCD) affects millions worldwide but has limited treatment options, most of which carry significant side effects. At present, the only curative treatment for SCD is allogeneic or gene‐modified autologous hematopoietic stem cell (HSC) transplantation (Tx).

Diagnosis of α-thalassemia using droplet digital PCR [PDF]

, 2019
Most α-thalassemia occurs due to a large deletion in the α-globin gene. Common α-thalassemia with known mutations, such as Southeast Asian (SEA) type is readily diagnosed by Gap-PCR.
