Anemia News and Research

RSS

Anemia is a decrease in normal number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency. The three main classes of anemia include excessive blood loss (acutely such as a hemorrhage or chronically through low-volume loss), excessive blood cell destruction (hemolysis) or deficient red blood cell production (ineffective hematopoiesis). Anemia is the most common disorder of the blood. There are several kinds of anemia, produced by a variety of underlying causes. Anemia can be classified in a variety of ways, based on the morphology of RBCs, underlying etiologic mechanisms, and discernible clinical spectra, to mention a few.

New gene editing approach bypasses disease-causing mutations

A new approach to gene editing using the CRISPR/Cas9 system bypasses disease-causing mutations in a gene, enabling treatment of genetic diseases linked to a single gene, such as cystic fibrosis, certain types of sickle cell anemia, and other rare diseases.

Subcutaneous injection of teclistamab drug shows promise in treating aggressive multiple myeloma

A subcutaneous injection of the immune-boosting drug teclistamab was found to be safe and elicit responses in a majority of patients with relapsed or refractory multiple myeloma, according to findings from a multi-institutional phase I study being presented by Alfred L. Garfall, MD, an assistant professor of Medicine in the division of Hematology-Oncology in the Perelman School of Medicine at the University of Pennsylvania, at the annual American Society of Hematology & Exposition Meeting on Dec. 5 (abstract #180).
