Introduction: Thyroid hormones play an important role in bone metabolism. The potential action of prolonged levothyroxine therapy on bone mass reduction is still a matter of debate.Objective: The aim of the present study was to assess the effects of levothyroxine treatment on bone mineral density (BMD) and biochemical bone turnover markers.Methods: We determined thyroid function – TSH and free T4 (FT4), r...

Background: Obesity represents a cardiovascular risk factor. Monocyte chemoattractant protein-1 (MCP-1) is a known regulator of monocyte recruitment to sites of inflammation, and participates at the early phases of atherogenesis. Apolipoproteins, as part of the lipoprotein particles, are classically coupled with cardiovascular risk distinction.Aims: To assess the association of anthropometric parameters, insulin resistance and MCP-1 levels with classic l...

Background: Although acyl–ghrelin has been considered essential for ghrelin’s GH-releasing activity, several recent in vitro studies have shown that desacyl–ghrelin exhibits biological activities on metabolism and proliferation of adipocytes, myocytes, cardiomyocytes, and myelocytes. The full desacyl–ghrelin biological activity still remains a matter of debate.Aims: To assess desacyl–ghrelin circulating levels and its R51Q...

Background: Adiponectin is an adipokine with anti-diabetic properties. Recently, retinol binding protein-4 (RBP4) was identified as an adipokine associated with insulin resistance (IR) and a potential marker for type 2 diabetes (T2D) development.Aims: To compare adiponectin and RBP4 circulating levels according to presence/absence of diabetes/prediabetes, in obese women. To study the degree of association of those adipokines with indexes of IR and insuli...

Background: Adiponectin is an important adipokine to which have been attributed anti-diabetic and anti-atherogenic properties. Excess of abdominal fat deposition is undoubtedly assumed as a cardiometabolic risk factor. It has been hypothesized that peripheral deposition of fat could exert a protective effect in cardiometabolic profile.Aims: To evaluate the influence of anthropometric parameters on adiponectin levels in both obese and normal-weight premen...

Introduction: Insulin autoimmune syndrome (IAS) is a clinical condition characterized by the presence of autoantibodies to insulin or insulin receptors in patients not previously treated with insulin. This syndrome has been reported mainly in Asia, and it is a rare cause of hypoglycemia in Caucasians. So far there are no reports of IAS in patients with type 2 diabetes mellitus never treated with insulin.Case report: The authors describe a 59-year-old Cau...

Background: Obesity is related to an increased cardiovascular risk, namely coronary heart disease risk (CHDr). Type 2 diabetes (T2D) is frequently associated with obesity and, by itself, is an important CHDr factor. Interventions that induce weight loss would be expected to attenuate CHDr in obese patients.Aims: To evaluate variation in cardiovascular risk profile one year after adjustable gastric banding (AGB), in obese patients (with and without T2D); ...
