Association between antithyroid peroxidase antibody and recurrent miscarriage.

Area of Science:

• Reproductive Endocrinology
• Immunology
• Women's Health

Background:

• Thyroid disease is common in childbearing women, second only to diabetes.
• Thyroid autoimmunity during pregnancy is associated with adverse outcomes like miscarriage and preterm birth.

Purpose of the Study:

• To investigate the correlation between anti-thyroid peroxidase (anti-TPO) antibodies and unexplained recurrent miscarriage.

Main Methods:

• A case-control study included 124 women: 62 with unexplained recurrent miscarriages and 62 healthy controls.
• Thyroid-stimulating hormone (TSH) and anti-TPO antibody levels were measured in both groups.

Main Results:

• The prevalence of positive anti-TPO antibodies was 19.4% in women with recurrent miscarriage, compared to 6.5% in controls.
• A statistically significant association was found (p=0.03, OR=3.48).

Conclusions:

• A significant relationship exists between anti-TPO antibodies and recurrent miscarriage.
• Recommend screening for TSH and thyroid antibodies in women with recurrent miscarriages.
• Further research on levothyroxine therapy for antibody-positive euthyroid women is suggested.
