Uterine CD56 and CD16 Cells in Refractory Antiphospholipid Antibody-Related Pregnancy Loss and Chromosomally Intact Abortuses: A Case-Control Study.

Aim: To evaluate the role of uterine natural killer (uNK) CD56 and CD16 cells in patients with refractory antiphospholipid, antibody-mediated, recurrent, pregnancy loss.

Settings And Design: A case-control study was conducted between 2012 and 2015 at a university hospital.

Patients And Methods: A group of 118 women with a history of antiphospholipid antibody syndrome experiencing fetal loss in spite of low dose aspirin (LDA) and low molecular weight heparin (LMWH) treatment in the current pregnancy were included in this study.
