Antithyroid antibodies and miscarriage. Maternal antithyroid antibodies and euploid miscarriage in women with recurrent early pregnancy loss Our study did not demonstrate an association between euploid miscarriage and maternal antithyroid antibodies in subjects with a history of REPL. Therefore testing or treatment in this cohort may not be warranted. The effect of thyroid autoimmunity TAI on the prevalence of recurrent miscarriage RM is highly debatable.
No meta-analysis has been published in the past decade to investigate the impact of TAI on women with RM. Thyroid peroxidase TPO antibodies develop when the immune system attacks the thyroid itself. One in 10 women with normal thyroid function have TPO antibodies.
Previous research showed TPO antibodies are associated with an increased risk of miscarriage and preterm birth. During pregnancy there is an increase demand for thyroid hormone.

A doubling of the miscarriage rate was reported in antithyroid microsomal antibody positive women as contrasted to women who were negative for.

22 found that women with antithyroid antibodies had a higher rate of miscarriage than women without antithyroid antibodies 17 vs. Miscarriage is associated with antibodies – even with normal TSH – there is debate about what to do but a low dose 25-50mcg of levothyroxine may decrease.
