Background: The discharge from the hospital of insulin-treated hyperglycemic patients is always challenging. This is even more so in patients requiring glucocorticoid treatment, such as those with COVID-19.
Patients And Methods: A retrospective monocentric study of 23 inpatients was conducted with newly diagnosed or already known diabetes mellitus (DM) who were naïve to insulin treatment, and who were hospitalized with COVID-19 in non-critical settings and then discharged.
Objective: Decreased renal function has been consistently included among factors prompting recommendation for surgery in primary hyperparathyroidism (PHPT). However, most retrospective studies addressing this issue did not show an improvement in renal function after parathyroidectomy (PTX). The aim of this study was to investigate changes in renal function after PTX in PHPT patients subdivided according to renal function at diagnosis.
View Article and Find Full Text PDFObjective: The recent Fourth Workshop on the Management of Asymptomatic primary hyperparathyroidism (PHPT) maintained the threshold of 60 mL/min for decreased renal function, below which surgery is recommended. This study investigated the relationship between different stages of renal insufficiency and parathyroid hormone (PTH) levels in an updated case series of PHPT patients.
Methods: This was a retrospective, cross-sectional study involving 379 consecutive PHPT patients.
Objective: (1) To evaluate the prevalence of silent nephrolithiasis in patients with primary hyperparathyroidism (PHPT) compared with controls, and (2) To characterize clinically PHPT patients with silent renal stones.
Methods: We reviewed clinical data for 141 patients with PHPT and without symptoms or history of nephrolithiasis in whom renal ultrasonography was performed at diagnosis. A total of 141 sex- and age- matched subjects with abdomen ultrasonography obtained for reasons different from urinary symptoms served as controls.
Introduction: Evidence of crosstalk between bone and insulin metabolism has been identified. In primary hyperparathyroidism (PHPT), scant data exist on this relationship.
Aim: To evaluate the relationship between insulin levels or sensitivity and bone mineral density (BMD) in PHPT.
Background: Vitamin D deficiency (VDD) is common in patients with primary hyperparathyroidism (pHPT), and this could affect the clinical expression of the disease. However, few North American or North European studies have addressed this issue, showing vitamin D repletion in only about one-third of the patients.
Subjects And Methods: Vitamin D status was evaluated both in an observational study in a series of 206 consecutive patients with pHPT at diagnosis and in a case-control analysis with 113 age- and sex-matched healthy blood donors.

Aims: Primary hyperparathyroidism (pHPT) is characterized by an increased frequency of glucose tolerance abnormalities associated with insulin resistance. Few studies evaluated the prevalence of metabolic syndrome (MetS) in pHPT and whether there are differences between asymptomatic pHPT patients and symptomatic ones. Thus, we sought to investigate the prevalence of MetS in pHPT patients in comparison to the prevalence of MetS in Italian population.
View Article and Find Full Text PDFOsteocalcin (OC) has been proposed as a regulator of insulin sensitivity in both humans and other animals. Primary hyperparathyroidism (PHPT) is characterized by high OC levels and insulin resistance. The aim of this study was to evaluate whether in PHPT the link between OC levels and blood markers of insulin resistance was maintained.

But the diagnostic value of measuring IGF-I levels has been recently revisited. It has been confirmed that normal IGF-I levels do not rule out severe GHD in adults.

The procedures of these tests generally include GH measurement every 15 min from baseline up to 90-120 min. Aim of our study was to verify if the procedure of these tests could be usefully shortened in clinical practice.
View Article and Find Full Text PDFObjective: Ghrelin, a 28 amino acid acylated peptide, is a natural ligand of the GH secretagogues (GHS) receptor (GHS-R), which is specific for synthetic GHS. Similar to synthetic GHS, ghrelin strongly stimulates GH secretion but also displays significant stimulatory effects on lactotroph and corticotroph secretion. It has been hypothesized that isolated GH deficiency (GHD) could reflect hypothalamic impairment that would theoretically involve defect in ghrelin activity.

To this goal we evaluated the GH response to GHRH (1 microg/kg iv) + arginine (ARG) (0.5 g/kg iv) test which is one of the most potent and reproducible provocative tests of somatotroph secretion, in 67 children with FSS [50 boys and 17 girls, age 10.

The aim of this multi-center collaborative study was to evaluate basal and stimulated GH secretion in a large series of adult PES patients. The study group consisted of 51 patients [41 women and 10 men, age range: 20-78 yr; (mean+/-SD) 47+/-11 yr]; results were compared with those in normal subjects (Ns) (Ns: no.

Adults with growth hormone (GH) deficiency (GHD) have impaired health, which improves with GH replacement. GHD in adulthood leads to impairment in body composition and structure functions as well as to deranged lipoprotein and carbohydrate metabolism leading to increased cardiovascular morbidity. Therefore the transition adolescent in whom severe GHD is confirmed has to continue GH replacement with an appropriate age-related dosage.
View Article and Find Full Text PDFWithin an appropriate clinical context, severe GH deficiency (GHD) in adults has to be defined biochemically by provocative testing of GH secretion. Patients with childhood-onset GHD need retesting in late adolescence or young adulthood to verify whether they have to continue recombinant human GH treatment. GHRH + arginine (GHRH+ARG) is the most reliable alternative to the insulin-induced hypoglycemia test (ITT) as a provocative test for the diagnosis of GHD in adulthood, provided that appropriate cut-off limits are assumed (normal limits, 16.

View Article and Find Full Text PDFBackground: Diagnosing GH deficiency in adults is difficult due to the age-related variations of GH/IGF-I axis and the influence of nutrition. Nowadays, GH replacement is allowed for patients with GH peak to provocative stimuli < 3 micrograms/L. Somatotrope insufficiency is present in hypopituitarism but also in obesity and hypercortisolism.

To this goal we studied the effects of rhGH and/or GHRH administration on the GH response to GHRH or hexarelin (HEX), a peptidyl GH secretagogue, in normal short children. In 34 prepubertal children (12 girls and 22 boys, age 8.
