AIMS/HYPOTHESIS Intramyocellular lipids, including ceramide, a second messenger in the sphingomyelin signalling pathway, might contribute to the development of insulin resistance. The aim of our study was to assess parameters of the skeletal muscle sphingomyelin signalling pathway in men at risk of developing type 2 diabetes. METHODS We studied 12 lean(More)
Resistin is a cysteine-rich adipokine originally described as a molecular link between obesity and insulin resistance in rodents. In this study, we hypothesised that serum resistin concentrations are elevated in patients with gestational diabetes mellitus (GDM) when compared with pregnant women with normal glucose tolerance (NGT) and related to(More)
Common polymorphisms in the transcription factor 7-like 2 gene (TCF7L2) have been associated with type 2 diabetes in different populations and recently with LADA, but not with type 1 diabetes. The aim of our study was to investigate association between the rs7903146 polymorphism in the TCF7L2 gene and LADA in Polish patients. Link between the "high risk for(More)
INTRODUCTION Autoimmune diabetes has different clinical manifestations related to the age at onset. It is divided into several subtypes, including "classical" type 1 diabetes (T1D) and latent autoimmune diabetes in adults (LADA). The LADA is considered a slowly progressing subtype of autoimmune diabetes, although the clinical picture is more similar to type(More)
AIMS AND METHODS In this study we measured: (1) serum visfatin concentrations in pregnant women with normal glucose tolerance (NGT) and gestational diabetes mellitus (GDM) between 26 and 33 weeks of gestation, using two immunoassays: EIA and ELISA; (2) serum visfatin levels (ELISA) and its mRNA expression (quantitative real-time PCR) in subcutaneous adipose(More)
BACKGROUND Visfatin, a protein secreted by adipose tissue, is suggested to play a role in pathogenesis of insulin resistance. In polycystic ovary syndrome (PCOS), insulin resistance might be involved in the development of endocrine and metabolic abnormalities. The aim of the study was to asses the relation between serum visfatin concentration and insulin(More)
OBJECTIVE To investigate the efficacy and safety of topiramate in obese subjects with type 2 diabetes treated with metformin. DESIGN This was a multicenter, double-blind, placebo-controlled trial. All subjects received a non-pharmacological program of diet, exercise and behavioral modification throughout the study; the assigned diet was 600 kcal/day less(More)
OBJECTIVE There is growing evidence that adiponectin function is related to the pathogenesis of insulin resistance. Insulin resistance might be present even in lean subjects with a strong family history of type 2 diabetes. The aim of the study was to look for adiponectin's role in the pathogenesis of insulin resistance in offspring of type 2 diabetic(More)
INTRODUCTION To assess the usefulness of circulating IL-16 and RANTES measurements as markers of Graves' orbitopathy (GO) activity and to estimate the role of these cytokines in GO pathogenesis. MATERIAL AND METHODS 42 individuals were divided into four groups: Group 1 comprised 15 euthyroid patients with clinical symptoms of GO who underwent(More)
CONTEXT Ghrelin and leptin are hormones regulating appetite and metabolic processes. Adiponectin plays an important role in the modulation of glucose and lipid metabolism. OBJECTIVE The objective of the study was to evaluate the levels of plasma ghrelin, leptin, and adiponectin in obese subjects treated with bioenterics intragastric balloon (BIB),(More)
