Objective: Women with Hashimoto thyroiditis (HT) could have fertility problems. Serum anti-Müllerian hormone (AMH), which reflects functional ovarian reserve, is decreased in women with HT. The aim of the present study was to investigate the relation between serum levels of AMH and insulin resistance in women with HT compared to control group. Patients and methods: We examined 193 women: 37 subjects with HT, without previous history of treatment wit...

Aim: The aim of our study was to evaluate the influence of recombinant human thyroid-stimulating hormone (rhTSH) on the efficacy of radioiodine therapy in patients with non toxic nodular goitre with low RAIU.Materials and methods: The study was performed on 50 patients with non toxic nodular goitre (36 females and 14 males, aged 34–75 years) referred for radioiodine therapy. All patients had low RAIU (8–16%), 24 h after a diagnostic dose of I-1...

A young woman aged 23 years, with non-toxic goiter was treated in our Department. Serum levels of FT4, FT3 and TSH were within normal range, high resolution ultrasonography show very large glands (60 ml), with large nodule in left lobe and smaller one in the right lobe. Malignancy was ruled out by ultrasound-guided fine-needle aspiration biopsy. Thyroid radioiodine scintigraphy showed homogenous and diffuse uptake in the right lobe, with very low uptake i...

Before the introduction of mandatory salt iodination in 1997 the North-Eastern Region of Poland was known to be a moderate iodine deficiency area. It was also exposed to ionizing radiation after the Chernobyl accident in 1986. The aim of the present study was to evaluate the descriptive epidemiological features of incident thyroid cancers diagnosed among the residents of this area between 1996 and 2007. The Regional Cancer Surveillance Program was used to collect data on 834 n...

Aim: Clinical studies in Hashimoto thyroditis (HT) confirm, that even a minor thyroid dysfunction is related to significant changes in body mass. Betatrophin, also known as TD26/RIFL/lipasin/ANGPTL8/C19orf80, is a novel protein predominantly expressed in human liver and adipose tissue. Stimulators of betatrophin, such as thyroid hormones are usually relevant to energy expenditure or thermogenesis. The mechanisms of action of betatrophin are still unknown. In the present study ...

Introduction and aims: To date we have had some evidence that betatrophin is associated with insulin resistance. Some studies have demonstrated that betatrophin levels are elevated in type 2 diabetes, obesity and gestational diabetes. It has been shown that in mice betatrophin significantly improves beta cell function and glucose tolerance. This is the first study on betatrophin in which pregnant women were observed during all trimesters and in postpartum period to evaluate it...

Background: Interleukin-15 and -6 play a role in an inflammation, autoimmune, infectious and cancerous processes. Their increased concentrations were observed in psoriasis, asthma, multiple sclerosis and type 2 diabetes. However, the role of IL-15 and IL-6 in autoimmune diabetes (AD) pathogenesis is still unknown.Aim: The aim of our study was to assay circulating IL-15 and IL-6 levels in newly diagnosed AD patients, their I° relatives and healthy co...

Introduction and aims: TGF-β1 participates in the pathogenesis of autoimmune diseases e.g. diabetes, Hashimoto disease, autoimmune digestive system disorders. The aim of our study was to evaluate TGF-β1 levels during pregnancy and after childbirth in women who developed postpartum thyroiditis (PPT) in comparison to the healthy control group (CG) and women with positive anti-thyroid antibodies (ATA+) who did not develop PPT.Material and method: ...

Purpose: Recent reports strongly suggest that at least some cases of Hashimoto’s thyroiditis (HT) may be closely associated with IgG4-related disease. In the present study we aimed to find out, whether the measurement of serum IgG4 allows for an identification of distinct types of HT, with different clinical, sonographic and serologic characteristics.Methods: The group studied consisted of 53 patients with HT and 28 healthy individuals. All the part...

Background and aims: In patients with type 2 diabetes, elevated tumor necrosis factor α (TNFα), C-reactive protein (CRP), chemerin, fetuin-A, have been reported. However, it is not entirely clear whether these alterations in adipokine serum concentrations are already present in prediabetic states and in type 1 diabetes. The aim of the study was to investigate whether adipokine profiles (chemerin, fetuin-A, TNFα) and inflammatory markers (CRP) are associated with...
