The presence or absence of the Rhesus factor determines compatibility during transfusions.
c. Rh Incompatibility and Hemolytic Disease of the Newborn
Rh incompatibility poses a significant risk during pregnancy, particularly for Rh-negative mothers carrying Rh-positive fetuses.
When an Rh-negative mother is exposed to Rh-positive blood, such as during childbirth or prior blood transfusions, her immune system can develop antibodies against the Rhesus factor.
These antibodies can then cross the placenta and attack the red blood cells of an Rh-positive fetus, leading to hemolytic disease of the newborn (HDN).
This condition can cause severe anemia and other complications in the baby.
d. Prevention through RhoGAM
Before the discovery of the Rhesus factor, some people believed that the problem of the loss of babies other than the first was not a medical condition. In some quarters, it was thought to be witchcraft.
So how did the discovery of the rhesus factor affect society? To prevent Rh sensitization in Rh-negative mothers, a medication called Rho(D) immune globulin, or RhoGAM, is administered.
RhoGAM works by suppressing the mother’s immune response to the Rhesus factor, thereby preventing the development of antibodies that could harm future pregnancies.
This development has been a game-changer in ensuring the health and well-being of Rh-negative mothers and their Rh-positive babies.
e. Blood Transfusion Compatibility:
In blood transfusions, the Rh factor plays a crucial role in determining compatibility. Blood recipients must receive compatible blood to avoid adverse reactions.
For example, an Rh-negative individual can receive both Rh-negative and Rh-positive blood since they lack the Rhesus antigen.
However, an Rh-positive individual can only receive Rh-positive blood to prevent potential antibody reactions.
4. How did the discovery of the rhesus factor affect society? The Global Distribution Pattern of Blood Group: The Rhesus Factor’s Influence
The global distribution of blood groups reveals interesting patterns. It is estimated that approximately 85% of the world’s population is Rh-positive, with the remaining 15% being Rh-negative.
However, these percentages can vary significantly depending on geographical location.
For example, studies have shown that the Rh-negative blood type is more prevalent among Europeans, while Rh positivity is more common in Asian and African populations.
The evolutionary factors that have shaped the global distribution of blood groups are still being explored.
One theory suggests that the prevalence of certain blood types in specific regions is linked to protection against infectious diseases.
For instance, the higher incidence of Rh-negative blood types in Europe may be associated with resistance to certain parasites or pathogens present in that region historically.
How did the discovery of the rhesus factor affect society? In addition to its influence on disease susceptibility, the global distribution of the Rhesus factor has significant implications for blood transfusion services.
Individuals with Rh-negative blood are considered “universal donors” as their blood can be given to both Rh-positive and Rh-negative recipients.
However, Rh-negative individuals can only receive blood from other Rh-negative donors. This knowledge is crucial for ensuring safe and compatible blood transfusions worldwide.
💡 Key Takeaway: The presence or absence of the Rhesus factor has played a pivotal role in shaping the global distribution of blood groups. Understanding these patterns provides insights into human evolution, and disease susceptibility, and ensures compatibility in blood transfusion services.
