Introduction: Diabetic nephropathy is the main global cause of end stage renal disease. According to the annual report from the Portuguese National Diabetes Observatory, in 2013, the prevalence of diabetes mellitus (DM) in new cases of chronic kidney disease was 31.2 and 11.1% in kidney transplant patients.Aim: To characterise the population of type 2 diabetic patients admitted in diabetes and kidney transplant consult (DKTC), comparing those admitted be...

Introduction: Diabetes mellitus is a common metabolic complication after kidney transplantation, occurring with a frequency of 15–30% in the first year. However, despite the high incidence, there are described few cases of diabetic nephropathy with nodular glomerulosclerosis of the allograft.Case: Female patient, 49, with autosomal dominant familial renal poliquistose diagnosed at 17 and progression for chronic end-stage renal disease, underwent ren...

Introduction: Risk of vertebral fracture (VFx) is in part independent of bone mineral density (BMD) in primary hyperparathyroidism (PHPT). The aim of this study was to examine whether other factors, including the genotype of common polymorphisms in the calcium-sensing receptor (CASR) gene, are associated with VFx.Patients and methods: In 266 Caucasian PHPT patients, serum calcium, phosphate, creatinine, total alkaline phosphatase, intact PTH, 25-hydroxyv...

Background: Pegvisomant(PegV) and Pasireotide LAR(Pasi) are commonly used in acromegaly patients resistant to first-generation SRLs. Predictors of response to therapy with PegV and Pasi in this subset of patients are still unclear. These findings may be useful in choosing the most appropriate therapeutic option for the personalized treatment of patients affected by more aggressive disease. We aimed to identify individual predictors of responses.Methods: ...

Pasireotide (PAS) has a safety profile similar to first-generationsomatostatin analogues (SSA), except for a higher frequency of hyperglycaemia-related adverse events (AEs). However, consensus on the best management of PAS-induced hyperglycaemia in acromegalic patients has still to be defined. The current study aims at investigating the effects of long-term PAS treatment on glucose metabolism, by evaluating the clinical management of hyperglycemia-relatedAEs in acromegalic pat...

Introduction: The need of a long-term follow-up in adrenal incidentalomas (AI) is debated and data on cardiovascular events (CVE) are lacking.Methods: In this retrospective study all patients referred to seven Italian Endocrine Centers for AI, without signs of hypercortisolism at baseline and with a ≥5 years follow-up (80.7±30 months, range 60–286), were enrolled. From 171 patients (121 F) aged 59.5±10.2 years (range 25–79) the ...

The fracture risk in primary hyperparathyroidism (PHPT) is partially independent of bone mineral density (BMD) and seems to depend on decreased bone quality, which is still reliably assessed only with invasive techniques. Trabecular bone score (TBS) is a grey-level texture measurement acquired during a dual X-ray absorptiometry (DXA) lumbar spine scan and it has been recently proposed as index of bone quality. This study is aimed to assess the role of TBS in predictin...

Objective: In patients with adrenal incidentalomas (AI) the metabolic effect of the recovery of subclinical hypercortisolism (SH) is debated. The aim of this study was to determine the effect of the surgical and conservative approaches on the metabolic syndrome in AI patients with and without SH.Patients: One hundred and eight AI patients were studied; SH was diagnosed in the presence of >2 out of: urinary free cortisol >70 μg/24 h (193 nmol...

Objective: Subclinical hypercortisolism (SH) has been associated with increased prevalence of hypertension, type 2 diabetes mellitus, dyslipidemia, central obesity, osteoporosis and vertebral fractures. We aimed to investigate the accuracy of different SH diagnostic criteria in predicting the concomitant presence of these complications.Patiets: In this retrospective study we evaluated data of 231 patients (120 females and 111 males) affected with adrenal...

The cytochrome P450 2W1 (CYP2W1) is an orphan enzyme able to activate anticancer pro-drugs and to metabolise endogenous substances as fatty acids and lysophospholipids. Aim of the study was to evaluate the frequency of CYP2W1 polymorphisms in patients with adrenocortical carcinoma (ACC) and correlate it with the sensitivity to mitotane, which represents the only approved drug for the treatment of advanced ACC.Methods: A multicenter retrospective study in...
