Study Title:

Serum leptin concentration in women of reproductive age with euthyroid autoimmune thyroiditis.

Study Abstract

INTRODUCTION:

Autoimmune thyroid disease (AITD) with elevated anti-thyroid peroxidase antibody (aTPO) levels appears in 12-25% of all women, apart from thyroid dysfunction. High titers of aTPO are more common in women with polycystic ovary syndrome and endometriosis. Elevated aTPO has been associated with infertility and poorer quality of life among euthyroid women, and may be related to other factors.
OBJECTIVES:

The aim of the study was to measure differences in serum leptin concentration between AITD+ and AITD- patients. Setting, patients and main outcome measures: The sample was comprised of 74 women who were hospitalized in the Department of Gynecological Endocrinology, Medical University of Warsaw. Data collected included age, body mass index (BMI), and serum aTPO, serum thyroid stimulating hormone (TSH), serum fT4, serum follitropin (FSH), serum estradiol and serum leptin. AITD positive status was defined as serum aTPO greater than 5.6 mIU/ml.
RESULTS:

Serum leptin concentrations were significantly higher in AITD+ patients compared to AITD- patients (17.13 ng/ml [SD 7.66] versus 12.78 ng/ml [SD 7.28]; p < 0.05). No differences by AITD status were found in age, BMI, TSH, FSH, estradiol and fT4.
CONCLUSIONS:

Serum leptin concentrations were higher in patients with AITD than in patients without AITD.
