Thyroid peroxidase antibodies, levels of thyroid stimulating hormone and development of hypothyroidism in euthyroid subjects

Thyroid peroxidase antibodies, levels of thyroid stimulating hormone and development of hypothyroidism in euthyroid subjects.

OBJECTIVE Thyroid peroxidase antibodies (TPOAbs) have been found to be related to the levels of thyroid stimulating hormone (TSH) and to predict future development of thyroid failure in selected populations. We investigated these relations in a euthyroid general population. DESIGN Cross-sectional investigation of the relationship of TPOAbs and levels of TSH in euthyroid subjects. Prospective ...

Ramadan Fasting and Thyroid Hormone Levels in Women with Hypothyroidism

The present study aimed to evaluate the impact of Ramadan fasting on the levels of thyroid hormones in fasting women with hypothyroidism and levothyroxine intake. Methods: Serum levels of free thyroxine (T4) and thyroid-stimulating hormone (TSH) we...

Serum cholesterol levels in middle-aged euthyroid subjects with positive thyroid peroxidase antibodies.

OBJECTIVE This study was designed to investigate serum cholesterol levels in middle-aged euthyroid subjects with positive thyroid peroxidase antibodies (TPOAbs). METHODS We screened 1607 euthyroid subjects aged 35-65 years old. All the subjects were divided into 2 groups (i.e., TPOAb-positive group, n=205; TPOAb-negative group, n=1402) according to the level of TPOAb. The subjects were then s...

The impact of thyroid-stimulating hormone levels in euthyroid women on intrauterine insemination outcome

BACKGROUND The aim of this study was to examine the effect of thyroid-stimulating hormone (TSH) levels on intrauterine insemination (IUI) outcomes among euthyroid women. METHODS A retrospective cohort study was conducted. A total of 302 women who started their first IUI cycle in our fertility center were included in this study. The patients were categorized into two groups based on their prec...
