BACKGROUND Recurrent pregnancy loss (RPL) is defined as two or more consecutive pregnancy losses before twenty weeks of gestation. It is caused by a variety of genetics and non-genetics factors. Thyroid autoimmunity could associate with pregnancy loss. OBJECTIVE To investigate the effectiveness of Levothyroxine in treatment of RPL in women with high auto-thyroid antibodies. MATERIALS AND ME...

Thyroid peroxidase (TPO) deficiency, caused by biallelic TPO mutations, is a well-established genetic form of congenital hypothyroidism (CH). More than 100 patients have been published, and the patients have been diagnosed mostly in the frame of newborn screening (NBS) programs. Correlation between clinical phenotypes and TPO activity remains unclear. Here, we report clinical and molecular find...

Thyroid peroxidase (TPO) autoantibody epitopes are largely restricted to an immunodominant region (IDR) on the extracellular region of the native molecule. Localization of the IDR has been a longstanding and difficult goal. The TPO extracellular region comprises a large myeloperoxidase-like domain, linked to the plasma membrane by two smaller domains with homology to complement control protein ...

We thank Professor Kim, who read our manuscript and provided helpful comments and advice. In our study published in volume 30, issue 3 of Endocrinology and Metabolism, we reported that there were no differences in mean concentrations of ghrelin among the three groups (hyperthyroid, hypothyroid, and euthyroid group) [1]. Prof. Kim suggested that it might be helpful to consider thyroid peroxidase...

The aim of this study was to evaluate thyroid peroxidase (TPO) mRNA expression in peripheral blood of patients with benign and malignant thyroid disease. Included were 120 thyroid cancer patients, 85 patients with goitre or Graves' disease (GD) and 54 healthy volunteers. TPO mRNA expression was analysed in peripheral blood by nested RT-PCR. In cancer patients, RT-PCR results were compared with ...

In this study we describe a novel mutation of the thyroid peroxidase (TPO) gene that resulted in a total iodide organification defect. TPO activity and thyroxine formation in thyroglobulin in the thyroid gland of the patient were below the limits of detection. However, TPO mRNA was detectable at a similar size and concentration as compared with normal thyroid tissues when measured by Northern b...

Correspondence to Dr Shaoke Chen; [email protected] ABSTRACT Objectives: Defects in the human thyroid peroxidase (TPO) gene are reported to be one of the causes of congenital hypothyroidism (CH) due to dyshormonogenesis. The aim of this study was to examine the TPO mutation spectrum and prevalence among patients with CH in the Guangxi Zhuang Autonomous Region of China and to define the rela...

We analyzed the kinetics of CD4 cells, human immunodeficiency virus (HIV) viral load, and autoantibodies in acquired immune deficiency syndrome patients with Graves' disease (GD) after immune restoration on highly active antiretroviral therapy (HAART; retrospective study). Five patients (median age, 41 yr) were diagnosed with GD after 20 (range, 14-22) months on HAART on the basis of clinical a...

BACKGROUND Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease caused by immune system-mediated tissue damage. Autoimmune thyroiditis (AT) is an organ-specific disease associated with production of a variety of antibodies such as antinuclear antibodies, anti-double-stranded DNA, anti-Ro antibodies and anti-cardiolipin antibodies. OBJECTIVES The aim of this study was to ev...

BACKGROUND The concept is now emerging that higher thyroid-stimulating hormone (TSH) and lower thyroid hormone levels within the euthyroid range may adversely affect atherosclerosis. The aim of this study was to investigate the potential association between thyroid parameters and lipids profile in a cohort of euthyroid diabetic subjects. METHODS Four hundred and sixty-two euthyroid type 2 dia...
