An immunohistochemical staining study for comparison of the T lymphocyte subgroups and the uterine natural killer cells in the decidua from spontaneous abortions and voluntary pregnancy terminations

Abstract

Aim: To investigate the role of the decidual total T lymphocyte count, T cytotoxic (Tc) and T helper (Th) sub-populations and the uterin natural killer (uNK) cells in the pathogenesis of the spontaneous abortions (SA) and recurrent pregnancy loss (RPL) cases.

Materials and Methods: We included the SA (n:29) and the voluntary pregnancy termination (n:10) cases which were undergone suction curettage between January 2003-January 2005 at the Ege University Obstetrics and Gynecology Department and their paraffin blocks were obtained. 

Results: Median CD3+ T lymphocyte cell counts were not different between the control (314; 210-489), incomplete abortions (560;183-1602) and missed abortions (426;154-1102) groups (p:0.117). Median CD4+ Th cell counts were not different between the control (143; 87-203), incomplete abortions (236;77-735) and missed abortions (236;76-677) groups (p:0.441). Median CD8+ Ts cell counts were not different between the control (179; 105-279), incomplete abortions (239;90-820) and missed abortions (197;84-560) groups (p:0.530). Median CD56+ uNK cell counts were not different between the control (634; 554-1390), incomplete abortions (714;653-2165) and missed abortions (712;306-2108) groups (p:0.099).

Conclusion: Abortions and RPL are heterogeneous groups consisting of cases representing various pathogenetic origins. Aberrant immune mechanisms could be responsible for a subgroup if not in all cases. Further studies designed by classifying the cases karyotypically and utilizing more sophisticated methods (such as flow cytometry, gene expression and receptor activation analyses) are needed to elucidate the complicated role of the immune system elements in the spontaneous abortion cases.
