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: Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant condition characterized by varying combinations of endocrine tumors and commonly accompanying hyperplasia within the parathyroid gland, anterior pituitary and gastrointestinal tract. Heterozygous germline mutation of the tumor suppressor gene MEN1 is the most common cause of the disease. Molecular genetic testing of menin gene, in which mutation is known to cause MEN1 syndrome, detects pathogenic...

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...

Introduction: The transcription factor 7-like 2 gene (TCF7L2) has the strongest effect on the risk of type 2 diabetes but the mechanism for this is not fully understood. Some genetic variants are associated with pancreatic B-cell function and some single nucleotide polymorphisms show a significant correlation with obesity. The aim of the study was to analyze whether TCF7L2 variants may influence body weight and body fat content, as well as postprandial glucose metabolism in no...

Objectives: GH plays a crucial role in the regulation of metabolism of human cells. Nevertheless, a direct influence of this hormone on the proliferation, maturation and differentiation of human early hematopoietic stem/progenitor cells (HSPCs) has not been investigated thoroughly. Moreover, certain deviations of hematological parameters, such as anemia or leucopenia, are commonly observed in patients with growth hormone deficiency (GHD) syndrome, which might be substantially ...

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...

Aim: It is well known that T1D is associated with other autoimmune diseases. The aim of this study was to compare the prevalence of various auto-antibodies in first-degree relatives of patients with T1D and healthy individuals with negative family history of diabetes.Material and methods: The group studied consisted of 90 relatives and 60 healthy individuals. Serum concentrations of antibodies to anti-21-hydroxylase (21-OH-Abs), anti-gastric parietal cel...

Results of metabolomic studies showed the relation of branched-chain amino acids (BCAA) and aromatic amino acids (AAA) with metabolic disorders.Basing on this observation we assessed amino acid profile in 286 professionally active men (aged 36–60 years). 141 of them met the criteria of metabolic syndrome (MS) and remaining 142 served as controls.Quantitative analysis of BCAA (leucine-LEU, valine-VAL, isoleucine- ILE) and AAA (...

Introduction: Abnormal angiogenesis may contribute to impaired wound healing and the consequence of them is non-healing diabetic ulcers development. Therefore, the aim of the study was to evaluate the number of circulating EPCs, plasma levels of VEGF-A, sVEGF-R2 and FGF-2 in diabetic patients.Materials and methods: Totally, 75 subjects were enrolled: 45 patients with type 2 diabetes (mean age 67.1 years) and 30 healthy volunteers (mean age 63.3 years). P...
