Nipocalimab is an experimental high affinity, fully human, aglycosylated, effectorless immunoglobulin G (IgG) anti-FcRn monoclonal antibody. [1]For hemolytic disease of the newborn (HDFN), nipocalimab works by decreasing levels of alloantibodies and other circulating IgG antibodies in the mother without impacting immune function.
Hemolytic disease of the fetus and newborn (HDN) is a condition where the passage of maternal antibodies results in the hemolysis of fetal/neonatal red cells. The antibodies can be naturally occurring such as anti-A, and anti-B, or immune antibodies developed following a sensitizing event. [ 12 ]
Ravulizumab, sold under the brand name Ultomiris, is a humanized monoclonal antibody complement inhibitor medication designed for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome. It is designed to bind to and prevent the activation of Complement component 5 (C5). [8] [7]
The risk of hemolytic disease (including due to RhD) significantly increases if the mother has had a past transfusion of Rh-positive blood. [ 10 ] Exposure to fetal blood cells that can cause RhD alloimmunization can happen during normal pregnancy and delivery, miscarriage, amniocentesis, cordocentesis, chorionic villus sampling, external ...
Rh disease (also known as rhesus isoimmunization, Rh (D) disease, or rhesus incompatibility, and blue baby disease) is a type of hemolytic disease of the fetus and newborn (HDFN). HDFN due to anti-D antibodies is the proper and currently used name for this disease as the Rh blood group system actually has more than 50 antigens and not only the ...
Hemolytic disease of the newborn (anti-Rhc) can range from a mild to a severe disease. It is the third most common cause of severe HDN. Rh disease is the most common and hemolytic disease of the newborn (anti-Kell) is the second most common cause of severe HDN. It occurs more commonly in women who are Rh D negative.
The AAP recommends "In isoimmune hemolytic disease, administration of intravenous γ-globulin (0.5-1 g/kg over 2 hours) is recommended if the TSB is rising despite intensive phototherapy or the TSB level is within 2 to 3 mg/dL (34-51 μmol/L) of the exchange level .
