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 ...
Rh(D) status of an individual is normally described with a positive (+) or negative (−) suffix after the ABO type (e.g., someone who is A+ has the A antigen and Rh(D) antigen, whereas someone who is A− has the A antigen but lacks the Rh(D) antigen). The terms Rh factor, Rh positive, and Rh negative refer to the Rh(D
The entire Rh blood group system involves multiple antigens and genes. For Rh factor testing, however, only the Rhesus factor correlated to the RhD antigen is assayed. The RhD gene that codes for the RhD antigen is located on chromosome 1. This chromosome contains gene instructions for making proteins in the body. [3]
Rh o (D) Immune Globulin Intravenous [Human; Anti-D] is indicated for use in non-splenectomized, Rh o (D)-positive children with chronic or acute ITP, adults with chronic ITP, and children and adults with ITP secondary to HIV infection. Anti-D must be administered via the intravenous route when used in clinical situations requiring an increase ...
Generally, HDFN becomes worse with each additional Rh incompatible pregnancy. One cause of pre-eclampsia is an abnormal immune response towards the placenta. There is substantial evidence for exposure to partner's semen as prevention for pre-eclampsia, largely due to the absorption of several immune modulating factors present in seminal fluid ...
[12] [17] Women who have a blood type of rhesus negative (Rh negative) may require Rho(D) immune globulin. [8] Pain medication may be beneficial. [12] Emotionally, afterwards, sadness, anxiety or guilt may occur. [3] [18] Emotional support may help with processing the loss. [12] Miscarriage is the most common complication of early pregnancy. [19]
The Rh factor is an inherited protein found on the surface of red blood cells. [19] If the mother is Rh negative and the father is Rh positive, a fetus has at least a 50% chance of being Rh positive. [19] Rh incompatibility occurs when a mother has Rh-negative blood and her baby has Rh-positive blood. [19]
A threatened miscarriage is signs or symptoms of miscarriage, most often including bleeding that occurs in the first 20-weeks of a pregnancy. [28] Research has shown that supplementation of progesterone can lower the rate of miscarriage, however, it did not have an effect on lowering the rate of pre-term births and live births. [29]
