The term "Rhesus Isoimmunizations" refers to the process by which a mother's immune system produces antibodies against her baby's blood cells if they have a different Rh factor. The pronunciation of this term is [ ˈriːsəs aɪsoʊɪmjʊnɪˈzeɪʃənz ], where the first syllable is pronounced as "ree-sus" and is stressed. The second syllable "iso" is pronounced as "eye-so", and the final syllable is pronounced as "mun-i-zay-shuns." It is vital to spell medical terms correctly to ensure accurate communication and proper treatment.
Rhesus isoimmunization, also known as Rh isoimmunization or Rh incompatibility, is a medical condition that occurs when there is an incompatibility between the blood types of an expectant mother and her developing fetus. Specifically, it refers to the body's immune response to an antigen present on the surface of red blood cells, known as the Rh factor.
In most cases, this condition occurs when a woman with Rh-negative blood type becomes pregnant with a fetus who has Rh-positive blood type, inherited from the father. During pregnancy or childbirth, small amounts of the baby's Rh-positive blood may enter the mother's bloodstream. This exposure to the Rh antigen triggers the mother's immune system to produce antibodies against the Rh factor.
If a woman has been sensitized to the Rh factor due to a previous pregnancy or transfusion, her immune system will produce antibodies that can cross the placenta and attack the red blood cells of a subsequent Rh-positive fetus. This immune response can lead to a condition called hemolytic disease of the newborn (HDN) or erythroblastosis fetalis, which can cause anemia, jaundice, and other serious complications in the baby.
To prevent Rhesus isoimmunization, Rh-negative women are often given Rh immunoglobulin (RhIgG) injections during pregnancy. This medication helps prevent the mother's immune system from reacting to the Rh factor, reducing the risk of sensitization. However, if isoimmunization has already occurred, close monitoring and medical intervention, such as intrauterine transfusion, may be necessary to manage the condition and ensure the well-being of the baby.
The term "Rhesus Isoimmunizations" is derived from two main components: "Rhesus" and "Isoimmunizations".
1. Rhesus: The word "Rhesus" refers to the Rhesus monkey. The monkey was named after the Rh blood group system, which was discovered in Rhesus monkeys before being identified in humans. The Rh blood grouping system refers to a specific antigen called Rh factor found on the surface of red blood cells. The monkey name was then applied to the antigen system, and subsequently to related medical terms.
2. Isoimmunizations: The term "isoimmunizations" is formed from two components - "iso" and "immunizations".
- "Iso" is a prefix derived from the Greek word "ísos", meaning "equal" or "same". In medical terminology, it often represents "equal" or "uniform".
