Immunologic testing and immunotherapy in recurrent spontaneous abortion.

J A McIntyre, W P Faulk, V R Nichols-Johnson

    Obstetrics and Gynecology
    |February 1, 1986
    PubMed
    Summary

    Couples with recurrent pregnancy loss showed distinct immune differences. Immunotherapy improved live birth rates in primary aborters, suggesting immune factors impact recurrent spontaneous abortions.

    Area of Science:

    • Reproductive Immunology
    • Immunogenetics

    Background:

    • Recurrent spontaneous abortion (RSA) affects numerous couples.
    • Immune system dysregulation is implicated in RSA.
    • Understanding immune profiles in RSA is crucial for effective management.

    Purpose of the Study:

    • To investigate immunogenetic and immunological differences between primary and secondary RSA couples.
    • To evaluate the efficacy of immunotherapy and heparin therapy in RSA.

    Main Methods:

    • Analysis of human leukocyte antigen (HLA) sharing, antipaternal antibodies, and mixed lymphocyte reactions (MLR) in 161 RSA couples.
    • Categorization into primary and secondary aborters.
    • Immunotherapy with leukocyte infusions for primary aborters and heparin therapy for secondary aborters.

    Main Results:

    • Primary aborters exhibited increased HLA sharing with partners compared to controls.
    • Secondary aborters frequently had lymphocytotoxins and sera-inhibiting MLR.
    • Immunotherapy resulted in an 89% success rate for live births in primary aborters.
    • Heparin therapy showed mixed results in secondary aborters.

    Conclusions:

    • Distinct immunological profiles differentiate primary and secondary RSA.
    • Immunotherapy shows significant promise for improving pregnancy outcomes in primary RSA.
    • Further research is needed to optimize treatments for secondary RSA.
