An example of anti-Jra

J E Tritchler

    Transfusion
    |March 1, 1977
    PubMed
    Summary

    Anti-Jra antibodies are detected in individuals lacking the Jra antigen. One case involved a newborn experiencing hemolytic disease, identified during prenatal screening.

    Area of Science:

    • Immunology
    • Transfusion Medicine
    • Neonatal Care

    Background:

    • The Jra antigen is a high-frequency antigen in the red blood cell system.
    • Alloimmunization can occur in individuals lacking specific red blood cell antigens.
    • Antibodies against red blood cell antigens can cause hemolytic transfusion reactions and hemolytic disease of the fetus and newborn (HDFN).

    Observation:

    • Anti-Jra antibody was identified in a pregnant woman during routine prenatal screening.
    • The presence of Anti-Jra was noted in individuals who naturally lack the Jra antigen.
    • A hemolytic process was suspected in the newborn of the identified woman.

    Findings:

    • The study confirms the existence of Anti-Jra antibodies in individuals lacking the Jra antigen.
    • This antibody has been detected in at least 15 individuals.
    • The case highlights a potential association between Anti-Jra and hemolytic processes in newborns.

    Implications:

    • This finding is significant for blood banking and transfusion practices, particularly in prenatal screening.
    • Further investigation is warranted to understand the clinical significance and prevalence of Anti-Jra.
    • Awareness of Anti-Jra can improve the management of HDFN and guide compatible blood transfusions.
