Renal disease in pregnancy

F K Beller, W R Dame, H W Intorp

    American Journal of Obstetrics and Gynecology
    |December 1, 1976
    PubMed
    Summary

    Severe pre-eclampsia can worsen underlying renal disease, leading to complications like eclamptic convulsions and fetal death. Renal biopsy is crucial for diagnosing these conditions and understanding pregnancy

    Area of Science:

    • Nephrology
    • Obstetrics
    • Pathology

    Background:

    • Severe pre-eclampsia presents diagnostic challenges, particularly differentiating it from underlying renal diseases.
    • Pregnancy can significantly exacerbate pre-existing renal conditions, impacting both maternal and fetal outcomes.

    Purpose of the Study:

    • To investigate the effects of severe pre-eclampsia on patients with pre-existing renal disease.
    • To evaluate the diagnostic utility of renal biopsy in differentiating pre-eclampsia from other renal pathologies.

    Main Methods:

    • Renal biopsies were performed on 20 patients (11 primiparous, 9 multiparous) with severe pre-eclampsia.
    • Histopathological analysis included immune fluorescence staining for immunoglobulins and fibrinogen.
    • Fluorescence angiography and laboratory data were also assessed.

    Main Results:

    • Eclamptic convulsions and fetal deaths occurred in patients with renal disease, even without primary glomerular endotheliosis.
    • Renal disease was exacerbated by pregnancy, enabling earlier diagnosis.
    • Immune fluorescence showed distinct patterns for glomerulonephritis versus primary endotheliosis/nephrosclerosis.
    • Fibrin monomer formation increased regardless of underlying renal morphology, unlike fibrinogen breakdown products.

    Conclusions:

    • Renal biopsy is essential for accurate pathological classification and understanding the interplay between renal disease and pregnancy.
    • Pregnancy can unmask or worsen underlying renal conditions, necessitating careful evaluation.
    • Laboratory data alone is insufficient for differential diagnosis between primary endotheliosis and various renal diseases.
