Introduction: Immune-Checkpoint Inhibitors (ICI) are frequently associated with thyroid-related adverse events (AE). Several studies analyzed thyroid disfunctions during ICI therapy, but many aspects remain to be characterized, especially for the most recent anti-PD-1 drugs. The aim of this study is to determine incidence and characteristics of PD-1 inhibitors associated thyroid dysfunction.Methods: We retrospectively analyzed data of patients with advan...

Introduction: Adrenal Insufficiency (AI) is characterized by absolute or relative deficiency of glucocorticoids and adrenal androgen precursors. Patients with AI show an impaired quality of life, metabolic status, immune function and dysregulated circadian genes. Data on sexual function are scarce and often contradictory. The aims of the present study are to evaluate sexual dysfunction (SD) in women and men patients with AI and to investigate the effects of restoring a more ph...

Introduction: The role of Angiopoietin (Ang)/Tie2 kinase pathway in neuroendocrine neoplasms (NENs) has recently received increasing attention, but its clinical role remains unclear. Tie2-receptor inactivation favours chronic inflammation. The balance between its agonist and antagonist regulates its signalling. Aim of this study was to measure serum soluble Tie2 (sTie2) and Ang-2 in patients followed at the NETTARE Unit (NeuroEndocrine TAsk foRcE of ‘Sapienza’ Univer...

Hypopituitarism is a potential complication of trans-sphenoidal adenomectomy (TSA). Prediction of pituitary function (PF) recovery would inform hormonal replacement strategies. However, the frequency of re-testing of PF is variable across centres. The aim of this study was to determine rates, time and predictors of 6-weeks (6 w) recovery of hypothalamo-pituitary adrenal (HPA) and gonadal function after TSA.Methods: We performed a single-centre, retrospec...

Background: Hypopituitarism can occur post trans-sphenoidal adenomectomy(TSA). Accurate prediction of HPA axis recovery would inform hydrocortisone replacement strategies but there are limited studies on this. In our centre, HPA axis is assessed with pre-operative short synacthen test (SST), day-8 post TSA 9am cortisol and 6-week post-TSA SST. Patients are commenced on hydrocortisone post TSA until 6 weeks review.Methods: We performed a single-centre, lo...

Adrenal insufficiency (AI) requires life-long glucocorticoid (GC) treatment, which is associated with an increased risk of metabolic syndrome (MS), probably due to cortisol overexposure for multiple drug daily doses, together with an impairment of quality of life (QoL). Moreover treatment compliance (TC) is reported to be suboptimal in AI patients. The current study aimed at investigating the impact of the switch from twice/thrice daily conventional GCs to once daily dual-rele...

Background: Cyclical Cushing’s syndrome has been considered to be a rare clinical entity, characterised by periodic increases in cortisol levels followed by regression of the Cushing’s syndrome. The cycles of hypercortisolism may occur before the establishment of the diagnosis, rendering actual diagnosis difficult, or may occur after inadequate or ineffective treatment and affect disease management. The aim of this study was to investigate the prevalence of cyclicity...

Background: Little is known about possible predictors for hormonal function following pituitary surgery. Tumor consistency has recently emerged as a key factor in surgical planning for pituitary adenomas, influencing both the surgical outcome and the onset of postoperative complications. However, its impact on postoperative endocrine function has yet to be explored.Objectives: To evaluate the impact of tumor consistency on the development of postoperativ...

Background: Experimental studies on Klinefelter syndrome (KS) reported increased intratesticular testosterone (T) levels coexisting with reduced circulating levels. Abnormalities in testicular microcirculation have been claimed; however, no studies investigated in vivo testicular blood flow dynamics in humans with KS.Objective: To analyze the testicular microcirculation in KS by contrast-enhanced ultrasonography (CEUS) and correlate vascular par...

Background: The evaluation of postoperative adrenal insufficiency (PAI) and hypothalamus–pituitary–adrenal (HPA) axis recovery in patients with adrenal incidentaloma (AI) undergoing unilateral adrenalectomy remains limited.Objectives: We aimed to identify predictive factors for PAI development and evaluate HPA axis recovery in AI patients undergoing unilateral adrenalectomy.Methods: We retrospectively analysed adrenal fun...
