Background: Systematic exploration for anterior pituitary deficiency in patients harboring pituitary microadenomas is not well defined. So far, little is known on the involvement of pituitary function in clinically non-functioning pituitary microadenomas (CNFPM).Objective: To evaluate the prevalence of anterior pituitary insufficiency, defined as at least one hormonal deficiency, in patients diagnosed of CNFPM.Patients and methods:...

Objetive: To assess the clinical features of incidental clinically non-functioning pituitary adenoma (NFPA) and to analyze its natural history.Methods: A multicenter retrospective study in patients with NFPA followed-up from 1992 to 2015 was performed.Results: Fifty-seven patients were studied (29 women (50.9%); age 55.8±16.7 years. 43.9% were older than 60 years, 40.3% belonged to the age group of 40–60 years and 15.8% w...

Introduction: Hyperprolactinemia has been associated with several metabolic abnormalities both in glucose homeostasis, insulin sensitivity, and in lipid profile. Moreover, it has also been reported that many of them seem to improve after normalizing serum prolactin (PRL) concentrations.Objective: To study serum glucose, cholesterol and triglyceride in men with prolactinoma before and after chronic treatment with cabergoline.Patient...

Objective: To assess clinical outcome after pituitary surgery in patients nonfunctioning pituitary adenomas (NFPA) surgically treated in the past 3 decades in three tertiary referral hospitals.Methods: A multicenter retrospective study on clinical and pathological characteristics, treatment patterns, and outcome in patients with NFPA periodically followed up in specialized neuroendocrinology units who underwent surgery in the period 1982–2015 was pe...

Context: Acromegaly associated to schizophrenia was firstly reported ~60 years ago and, so far it is unclear whether this association is causal or not.Objective: We report on three new cases and discuss the potential pathophysiological mechanisms of this association.Results: We report two males and one female diagnosed with schizophrenia and treated for several years with antipsychotics who developed acromegaly due to a GH-secretin...

Aims: To evaluate the clinical features and long-term therapeutic outcome of giant prolactinoma (gPRLoma) in men and to compare them with those of a group of male patients with non-gPRL macroprolactinomas (non-gPRLomas).Patients and methods: A retrospective and multicenter study of gPRLomas in men diagnosed in a 20-year period was performed. Clinical data and treatment outcome were registered. The diagnosis of gPRLoma was established when the maximal tum...

Background: Pituitary adenomas (PA) and pheochromocytomas/paraganglioma (pheo/PGL) can occur in the same patient due to coincidence or of shared pathogenesis. There is evidence that, at least in some cases, classical pheo/PGL predisposing genes, may also play a role in pituitary tumorigenesis. A new condition called ‘the three P Association’ (3PAs) for the combination of PA with pheo/PGL has been recently described in patients with or without succinate dehydrogenase ...

Context: Ipilimumab is a human monoclonal antibody against cytotoxic T lymphocyte antigen-4 (CTLA-4), which enhances stimulation of cytotoxic T lymphocytes, resulting in an immune response against the tumour. This drug-induced hyperactivity of the immune system can lead to serious adverse effects including endocrine disorders such as autoimmune hypophysitis, thyroiditis and adrenal insufficiency.Objective: To report our experience on ipilimumab-induced h...
