A new study could explain some of the factors behind recurrent miscarriages, and help determine appropriate course of treatment:
The search for an effective treatment has been the cause of significant controversy in the field of medical research, centering on the role of natural killer cells (or NK cells) and the ability of steroids to prevent miscarriage.
Scientists have been uncertain about how these NK cells could contribute to a miscarriage and this has raised doubt over their importance in causing pregnancy loss.
Led by Professor Jan Brosens of Warwick Medical School, the team found that elevated uterine NK cells in the lining of the womb indicate deficient production of steroids. Deficient steroid production in turn leads to reduced formation of fats and vitamins that are essential for pregnancy nutrition.
This study, published in The Journal of Clinical Endocrinology & Metabolism, is the first of its kind to provide an explanation for why high levels of NK cells can cause miscarriage.
