Low plasma SHBG levels in overweight individuals are a biomarker for the metabolic syndrome and are predictive of type 2 diabetes and risk of cardiovascular disease. There are no in vivo models to study SHBG expression and regulation during obesity development. The main reason for this is that the obesity-prone rodent models cannot be used to study this issue since rodents unlike humans do not express the SHBG gene in their livers. We have developed by crossi...

Low circulating sex hormone-binding globulin (SHBG) is an independent risk factor for cardiovascular disease. Mediterranean diet has been associated with a decreased risk of cardiovascular disease. We have recently shown that olive oil consumption is associated with elevated SHBG serum levels and that PPARγ downregulation induced by oleoyl-CoA is an important underlying mechanism of such regulation. Red wine is also an important component of the Mediterranean diet and its...

Low plasma SHBG is an independent risk factor of cardiovascular disease. Our recent work has shown that SHBG gene expression can be regulated indirectly through HNF4α gene expression. In this regard, we have identified that an increase in hepatic palmitate induced by high carbohydrate diets and pro-inflammatory cytokines (TNFα and IL1β) was able to reduce hepatic HNF4α protein levels which, in turn, decreased SHBG production. The Mediterranean diet, in whic...

Human sex hormone-binding globulin (SHBG) is produced and secreted by the liver and it binds androgens and estrogens with high affinity. In blood, SHBG acts as a carrier of these sex steroids and regulates their bioavailability. Low plasma SHBG levels are associated with obesity, abdominal adiposity and metabolic syndrome, and predict the development of type 2 diabetes. In addition, an inverse relationship between plasma SHBG levels and risk of cardiovascular disease has been ...

Background: The aim of this case report is to underline the possible etiological link between paroxysmal supraventricular tachycardia (PSVT) and hypothyroidism, although supraventricular arrhythmias are ordinary features of hyperthyroidism. We present the case of a patient with repetitive episodes of PSVT whose autoimmune hypothyroidism was diagnosed and thyroxin replacement therapy leaded to remission of arrhythmia.Methods: A 47 year old women with a lo...

The empty sella syndrome (ESS) is caused by the herniation of the suprarahnoidian space into the sella turcica, generating the compression of the pituitary gland and, in most cases, a remodelling of the sella. The purpose of this study was to evaluate the etiology, the degree of hormonal deficit and the occurrence rate of the signs and symptoms accompanying ESS.Material and methods: We performed a descriptive, retrospective study by analysing the medical...

Low plasma SHBG levels are present in patients suffering chronic metabolic diseases, including obesity and non-alcoholic fatty liver disease (NAFLD). In overweight individuals, low plasma SHBG levels are a biomarker for the metabolic syndrome and predict a higher risk of suffering type 2 diabetes and cardiovascular disease. Our recent results demonstrate that SHBG is more than sex hormone carrier and its reduction in obese subjects play an active role in obesity and NAFLD deve...

This is a case of a patient diagnosed with small cell lung carcinoma after presenting with severe hyponatremia due to syndrome of inappropriate antidiuretic hormone secretion (SIADH) who was readmitted 7 months later with refractory hypokalemia and hyperglycaemia due to ectopic adrenocorticotrophic hormone secretion (EAS). A 65 year-old man presented in November 2018 with symptoms of nausea, vomiting, headaches and blurred vision. On examination he was clinically euvolemic. La...

It has been established in recent years that androgens are involved in the progression of castration resistant prostate cancer (CRPC). Although androgen deprivation therapy reduces the level of androgens and inhibits the androgen receptor, there are studies reporting that the androgen signaling axis is still involved in the development of CRPC. We have in a previous study shown that low level of β2-adrenergic receptor (ADRB2) is associated with shorter time to ...

Context: Hypothalamic obesity, subsequent cardiovascular disease (CVD), and relapses/progression have major impact on prognosis in childhood-onset craniopharyngioma (CP). We analyzed nuchal skinfold thickness (NST) on magnetic resonance imaging (MRI) performed for follow-up monitoring as a novel parameter for body composition (BC) and CVD in CP.Objective: Identify association of NST with body mass index (BMI), waist-to-height ratio (WHtR), caliper-assess...
