Hydatidiform mole and HLA. Methods for HLA-A,B,C determination.

H E Hansen, L O Vejerslev

    Journal of Immunological Methods
    |November 7, 1985
    PubMed
    Summary

    This study investigated genetic markers in hydatidiform moles, finding agreement between HLA-A,B types and chromosome origins. Researchers developed two HLA typing methods for molar tissue, with the cytotoxic technique proving more sensitive.

    Area of Science:

    • Reproductive biology
    • Genetics
    • Immunology

    Background:

    • Hydatidiform moles are abnormal pregnancies requiring accurate diagnosis.
    • Understanding the genetic origin of molar tissue is crucial for clinical management.
    • Histocompatibility antigen (HLA) typing can provide insights into tissue origins.

    Purpose of the Study:

    • To examine histocompatibility between patients, spouses, and molar tissue using genetic markers.
    • To develop and compare techniques for human leukocyte antigen (HLA)-A,B determination in molar tissue.
    • To correlate HLA-A,B typing results with chromosomal markers to elucidate the origin of molar tissue.

    Main Methods:

    • Development of two techniques for HLA-A,B determination: a cytotoxic microtechnique for cultured molar cells and a microabsorption method for frozen molar tissue.
    • Examination of 22 cases using either molar cell cultures or frozen tissue.
    • Comparison of HLA-A,B typing results with chromosomal markers.

    Main Results:

    • A general agreement was observed between the HLA-A,B type and the origin of the chromosomes in the examined cases.
    • The cytotoxic microtechnique for cultured molar cells demonstrated higher sensitivity compared to the microabsorption method for frozen tissue.
    • Both techniques provided valuable data for understanding the genetic basis of hydatidiform moles.

    Conclusions:

    • HLA typing, in conjunction with chromosomal analysis, is a valuable tool for determining the origin of hydatidiform moles.
    • The cytotoxic microtechnique is recommended for HLA typing of molar tissue due to its superior sensitivity.
    • Further research can build upon these findings to improve diagnostic accuracy and patient care for molar pregnancies.
